Android11之前的 在Android系统中设置默认Launcher启动器是一个涉及系统权限和配置的过程。通常这个过程不是通过简单地修改几个文件或设置就能完成的因为它需要系统级别的权限。不过我可以概述一下在Android源码级别如何设置或允许用户选择默认Launcher的大致步骤。
第一部分、android10之前
一.多个launcher 启动设置默认launcher的核心类
代码路径frameworks/base/core/java/com/android/internal/app/ResolverActivity.java
2.多个launcher 启动设置默认launcher的核心功能实现和分析
通过在系统中内置其他Launcher时在系统进入启动Launcher的过程中会在ResolverActivity.java中首先查询系统中由几个Launcher,当有多个Launcher时会让用户选择启动的Launcher,然后作为默认启动Launcher. 所以就来分析该怎么设置默认Launcher,而不用用户选择启动Launcher. 先来看下ResolverActivity.java的相关源码 UiThreadpublic class ResolverActivity extends Activity { Overrideprotected void onCreate(Bundle savedInstanceState) {// Use a specialized prompt when were handling the Home app startActivity()final Intent intent makeMyIntent();final SetString categories intent.getCategories();if (Intent.ACTION_MAIN.equals(intent.getAction()) categories ! null categories.size() 1 categories.contains(Intent.CATEGORY_HOME)) {// Note: this field is not set to true in the compatibility version.mResolvingHome true;}setSafeForwardingMode(true);onCreate(savedInstanceState, intent, null, 0, null, null, true);}/*** Compatibility version for other bundled services that use this overload without* a default title resource*/UnsupportedAppUsageprotected void onCreate(Bundle savedInstanceState, Intent intent,CharSequence title, Intent[] initialIntents,ListResolveInfo rList, boolean supportsAlwaysUseOption) {onCreate(savedInstanceState, intent, title, 0, initialIntents, rList,supportsAlwaysUseOption);}protected void onCreate(Bundle savedInstanceState, Intent intent,CharSequence title, int defaultTitleRes, Intent[] initialIntents,ListResolveInfo rList, boolean supportsAlwaysUseOption) {setTheme(R.style.Theme_DeviceDefault_Resolver);super.onCreate(savedInstanceState);// Determine whether we should show that intent is forwarded// from managed profile to owner or other way around.setProfileSwitchMessageId(intent.getContentUserHint());try {mLaunchedFromUid ActivityTaskManager.getService().getLaunchedFromUid(getActivityToken());} catch (RemoteException e) {mLaunchedFromUid -1;}if (mLaunchedFromUid 0 || UserHandle.isIsolated(mLaunchedFromUid)) {// Gulp!finish();return;}mPm getPackageManager();mPackageMonitor.register(this, getMainLooper(), false);mRegistered true;mReferrerPackage getReferrerPackageName();final ActivityManager am (ActivityManager) getSystemService(ACTIVITY_SERVICE);mIconDpi am.getLauncherLargeIconDensity();// Add our initial intent as the first item, regardless of what else has already been added.mIntents.add(0, new Intent(intent));mTitle title;mDefaultTitleResId defaultTitleRes;mUseLayoutForBrowsables getTargetIntent() null? false: isHttpSchemeAndViewAction(getTargetIntent());mSupportsAlwaysUseOption supportsAlwaysUseOption;if (configureContentView(mIntents, initialIntents, rList)) {return;}final ResolverDrawerLayout rdl findViewById(R.id.contentPanel);if (rdl ! null) {rdl.setOnDismissedListener(new ResolverDrawerLayout.OnDismissedListener() {Overridepublic void onDismissed() {finish();}});if (isVoiceInteraction()) {rdl.setCollapsed(false);}rdl.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);rdl.setOnApplyWindowInsetsListener(this::onApplyWindowInsets);mResolverDrawerLayout rdl;}mProfileView findViewById(R.id.profile_button);if (mProfileView ! null) {mProfileView.setOnClickListener(this::onProfileClick);bindProfileView();}initSuspendedColorMatrix();if (isVoiceInteraction()) {onSetupVoiceInteraction();}final SetString categories intent.getCategories();MetricsLogger.action(this, mAdapter.hasFilteredItem()? MetricsProto.MetricsEvent.ACTION_SHOW_APP_DISAMBIG_APP_FEATURED: MetricsProto.MetricsEvent.ACTION_SHOW_APP_DISAMBIG_NONE_FEATURED,intent.getAction() : intent.getType() : (categories ! null ? Arrays.toString(categories.toArray()) : ));}
在ResolverActivity.java中的onCreate中首先读取系统中的Home属性的Launcher列表然后在 ResolveListAdapter中展示Launcher的列表所以可以在这些直接设置默认的Launcher然后finish掉这个页面直接进入默认Launcher页面 具体修改为
--- a/frameworks/base/core/java/com/android/internal/app/ResolverActivity.javab/frameworks/base/core/java/com/android/internal/app/ResolverActivity.java-278,9 278,53 public class ResolverActivity extends Activity {intent.setFlags(intent.getFlags()~Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);return intent;}
-private void setDefaultLauncher(String defPackageName,String defClassName) {if ((defPackageName ! null defPackageName.trim().length() 1) (defClassName ! null defClassName.trim().length() 0)) {IntentFilter filter new IntentFilter();filter.addAction(android.intent.action.MAIN);filter.addCategory(android.intent.category.HOME);filter.addCategory(android.intent.category.DEFAULT);Intent intentnew Intent(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_HOME);ListResolveInfo list new ArrayListResolveInfo();list getPackageManager().queryIntentActivities(intent, 0);final int N list.size();ComponentName[] set new ComponentName[N];int bestMatch 0;for (int i0; iN; i) {ResolveInfo r list.get(i);set[i] new ComponentName(r.activityInfo.packageName,r.activityInfo.name);if (r.match bestMatch) bestMatch r.match;}ComponentName preActivity new ComponentName(defPackageName, defClassName);getPackageManager().addPreferredActivity(filter, bestMatch, set,preActivity);}}Overrideprotected void onCreate(Bundle savedInstanceState) {boolean firstBoot (Settings.Global.getInt(getApplication().getContentResolver(),default_home_launcher, 0) 0);String defPackageName Settings.Global.getString(getContentResolver(),launcher_pkgname);String defClassName Settings.Global.getString(getContentResolver(),launcher_classname);Log.e(TAG,pkgname:defPackageName---defClassName:defClassName);if(firstBoot !TextUtils.isEmpty(defPackageName)){try {setDefaultLauncher(defPackageName,defClassName);Intent defIntent new Intent();defIntent.setClassName(defPackageName, defClassName);defIntent.setAction(android.intent.action.MAIN);defIntent.addCategory(android.intent.category.HOME);defIntent.addCategory(android.intent.category.DEFAULT);startActivity(defIntent);Settings.Global.putInt(getApplication().getContentResolver(),default_home_launcher,1);this.finish();} catch (Exception e) {e.printStackTrace();}}ActivityDebugConfigs.addConfigChangedListener(mDebugConfigListener);// Use a specialized prompt when were handling the Home app startActivity()-1291,7 1335,6 public class ResolverActivity extends Activity {setContentView(mLayoutId);
在onCreate中的增加setDefaultLauncher(String defPackageName,String defClassName)这个设置默认Launcher的方法而PM的addPreferredActivity设置默认Launcher就实现了功能
二 在自定义服务里面设置默认Launcher
public class MdmManagerService extends IMdmManager.Stub {private static String TAG MdmManagerService;private Context mContext;private Handler mHandler new Handler(Looper.getMainLooper());public MdmManagerService(Context context){this.mContext context;mHandler.postDelayed(mRunnable, 0);//IntentFilter mintentnew IntentFilter(com.sprd.settings.action.apistart);//mContext.registerReceiver(mBroadcastReceiver,mintent);}private BroadcastReceiver mBroadcastReceiver new BroadcastReceiver() {Overridepublic void onReceive(Context context, Intent intent) {Log.e(TAG,action);//mHandler.postDelayed(mRunnable, 500);}};private Runnable mRunnable new Runnable() {Overridepublic void run() {Log.e(TAG, actionRun);try {//setStatusBarExpandPanelDisabled(true);String defaultLauncher SystemProperties.get(persist.sys.ployer.default.launcher, );if(TextUtils.isEmpty(defaultLauncher)){setDefaultLauncher(com.android.launcher3, com.android.launcher3.Launcher);//setDefaultLauncher(com.ployer.interfacedemo, com.ployer.interfacedemo.MainActivity);}} catch (Exception e) {e.printStackTrace();}}};private void setDefaultApplication(String roleName, String packageName) {RoleManager roleManager mContext.getSystemService(RoleManager.class);Executor executor mContext.getMainExecutor();ConsumerBoolean callback successful - {if (successful) {Log.e(TAG, setDefaultApplication packageName:packageName successful);}};roleManager.addRoleHolderAsUser(roleName, packageName, 0, android.os.Process.myUserHandle(), executor, callback);}public void setDefaultLauncher(String packageName, String className) throws RemoteException {Log.e(TAG, setDefaultLauncher:packageNamepackageName--className:className);final long ident Binder.clearCallingIdentity();try {if (isPkgInstalled(mContext, packageName)) {Settings.Global.putString(mContext.getContentResolver(),launcher_pkgname,packageName);Settings.Global.putString(mContext.getContentResolver(),launcher_classname,className);String value packageName / className;SystemProperties.set(persist.sys.ployer.default.launcher, value);setDefaultApplication(android.app.role.HOME,packageName);} else {Log.e(TAG, setDefaultLauncher packageName is not exist);}} catch (Exception e) {e.printStackTrace();}finally {Binder.restoreCallingIdentity(ident);}}private boolean isPkgInstalled(Context context, String packageName) {if (packageName null || .equals(packageName))return false;ApplicationInfo info null;try {info context.getPackageManager().getApplicationInfo(packageName, 0);return info ! null;} catch (Exception e) {Log.e(TAG, apk is not installed packageName: packageName);return false;}} 第二部分、android10之后
一、Launcher应用内置并设置为默认Launcher
主要利用ResolverActivity.java或ActivityManagerService.java来实现接下来我将分别举例说明
1.通过ResolverActivity.java设置为默认Launcher 主要是由addPreferredActivity设置默认Launcher实现。 改法一
代码路径frameworks/base/core/java/com/android/internal/app/ResolverActivity.java
以下基于Android11代码
protected void onCreate(Bundle savedInstanceState, Intent intent,CharSequence title, int defaultTitleRes, Intent[] initialIntents,ListResolveInfo rList, boolean supportsAlwaysUseOption) {setTheme(appliedThemeResId());super.onCreate(savedInstanceState);//addif(mResolvingHome){setDefaultLauncher();finish();return;}//add...}private void setDefaultLauncher() {try {final PackageManager pm getPackageManager();String defPackageName com.android.launcher3;//默认launcher包名String defClassName com.android.searchlauncher.SearchLauncher;//默认launcher类名IntentFilter filter new IntentFilter();filter.addAction(android.intent.action.MAIN);filter.addCategory(android.intent.category.HOME);filter.addCategory(android.intent.category.DEFAULT);Intent intent new Intent(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_HOME);ListResolveInfo list new ArrayListResolveInfo();list pm.queryIntentActivities(intent, 0);final int N list.size();ComponentName[] set new ComponentName[N];int bestMatch 0;for (int i 0; i N; i) {ResolveInfo r list.get(i);set[i] new ComponentName(r.activityInfo.packageName,r.activityInfo.name);if (r.match bestMatch) bestMatch r.match;}ComponentName preActivity new ComponentName(defPackageName, defClassName);pm.addPreferredActivity(filter, bestMatch, set, preActivity);} catch (Exception e) {e.printStackTrace();}}
改法二
代码路径frameworks/base/services/core/java/com/android/server/am/ActivityManagerService.java
boolean startHomeActivityLocked(int userId, String reason) {setDefaultLauncher();//调用设置默认launcher方法SystemProperties.set(persist.sys.boot.bootcomplete,1);if (mFactoryTest FactoryTest.FACTORY_TEST_LOW_LEVEL mTopAction null) {// We are running in factory test mode, but unable to find// the factory test app, so just sit around displaying the// error message and dont try to start anything.return false;}......
}private void setDefaultLauncher() {boolean mFirstLaunch true;String packageName 包名;//launcher包名String className 类名;if ((packageName ! null packageName.trim().length() 1) (className ! null className.trim().length() 0)) {if(mFirstLaunch){IPackageManager pm ActivityThread.getPackageManager();ArrayListIntentFilter intentList new ArrayListIntentFilter();ArrayListComponentName cnList new ArrayListComponentName();mContext.getPackageManager().getPreferredActivities(intentList, cnList, null);IntentFilter dhIF;for(int i 0; i cnList.size(); i){dhIF intentList.get(i);if(dhIF.hasAction(Intent.ACTION_MAIN) dhIF.hasCategory(Intent.CATEGORY_HOME)) {mContext.getPackageManager().clearPackagePreferredActivities(cnList.get(i).getPackageName());}}Intent intent new Intent(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_HOME);ListResolveInfo list new ArrayListResolveInfo();try {list pm.queryIntentActivities(intent,intent.resolveTypeIfNeeded(mContext.getContentResolver()),PackageManager.MATCH_DEFAULT_ONLY,UserHandle.getCallingUserId()).getList(); //add .getList()}catch (RemoteException e) {throw new RuntimeException(Package manager has died, e);}IntentFilter filter new IntentFilter();filter.addAction(Intent.ACTION_MAIN);filter.addCategory(Intent.CATEGORY_HOME);filter.addCategory(Intent.CATEGORY_DEFAULT);final int N list.size();ComponentName[] set new ComponentName[N];int bestMatch 0;for (int i 0; i N; i){ResolveInfo r list.get(i);set[i] new ComponentName(r.activityInfo.packageName,r.activityInfo.name);if (r.match bestMatch) bestMatch r.match;}ComponentName launcher new ComponentName(packageName, className);try{pm.addPreferredActivity(filter, bestMatch, set, launcher,UserHandle.getCallingUserId());} catch (RemoteException e) {throw new RuntimeException(Package manager has died, e);}}}}
2.通过ActivityManagerService.java设置为默认Launcher 主要修改getHomeIntent()将其替换成需要默认的Launcher即可。
代码路径frameworks\base\services\core\java\com\android\server\am\ActivityManagerService.java
改法一(常规)
Intent getHomeIntent() {
//addSettings.Global.putInt(mContext.getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1);Settings.Secure.putInt(mContext.getContentResolver(), Settings.Secure.USER_SETUP_COMPLETE, 1);String defStartPkg 你的包名;Intent queryIntent new Intent();final PackageManager mPm mContext.getPackageManager();queryIntent.addCategory(Intent.CATEGORY_HOME);///没有home可去掉queryIntent.addCategory(Intent.CATEGORY_LAUNCHER);queryIntent.setAction(Intent.ACTION_MAIN);ListResolveInfo homeActivities mPm.queryIntentActivities(queryIntent, 0);if(homeActivities ! null) {int activityNum homeActivities.size();ComponentName[] set new ComponentName[activityNum];for(int i 0; i activityNum; i){ResolveInfo info homeActivities.get(i);set[i] new ComponentName(info.activityInfo.packageName, info.activityInfo.name);if(defStartPkg.equals(info.activityInfo.packageName)){Intent intentaa new Intent(mTopAction, mTopData ! null ? Uri.parse(mTopData) : null);intentaa.setComponent(set[i]);intentaa.addCategory(Intent.CATEGORY_HOME);return intentaa;}}}
//addIntent intent new Intent(mTopAction, mTopData ! null ? Uri.parse(mTopData) : null);intent.setComponent(mTopComponent);if (mFactoryTest ! FactoryTest.FACTORY_TEST_LOW_LEVEL) {intent.addCategory(Intent.CATEGORY_HOME);}return intent;}
改法二(简化
Intent getHomeIntent() {Intent intent new Intent(mTopAction, mTopData ! null ? Uri.parse(mTopData) : null);//add//intent.setComponent(mTopComponent);intent.setComponent(new ComponentName(包名, 类名));//addintent.addFlags(Intent.FLAG_DEBUG_TRIAGED_MISSING);if (mFactoryTest ! FactoryTest.FACTORY_TEST_LOW_LEVEL) {intent.addCategory(Intent.CATEGORY_HOME);}return intent;}
二、普通应用内置并设置为默认Launcher
因为这类应用通常没有android.intent.category.HOME这个Category故无法使用上述常规方式来设置为默认应用使用需要我们另辟蹊径这边也是为各位提供两种方法。
1.强制替换 首先将应用设置为默认开机启动但因为没有android.intent.category.HOME这个Category所以提供通过ResolverActivity.java设置是不行的需要通过修改ActivityManagerService.java来实现只要把改法一中的queryIntent.addCategory(Intent.CATEGORY_HOME);注释掉即可
Intent getHomeIntent() {
//addSettings.Global.putInt(mContext.getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1);Settings.Secure.putInt(mContext.getContentResolver(), Settings.Secure.USER_SETUP_COMPLETE, 1);String defStartPkg 你的包名;Intent queryIntent new Intent();final PackageManager mPm mContext.getPackageManager();//queryIntent.addCategory(Intent.CATEGORY_HOME);///没有home可去掉queryIntent.addCategory(Intent.CATEGORY_LAUNCHER);queryIntent.setAction(Intent.ACTION_MAIN);ListResolveInfo homeActivities mPm.queryIntentActivities(queryIntent, 0);if(homeActivities ! null) {int activityNum homeActivities.size();ComponentName[] set new ComponentName[activityNum];for(int i 0; i activityNum; i){ResolveInfo info homeActivities.get(i);set[i] new ComponentName(info.activityInfo.packageName, info.activityInfo.name);if(defStartPkg.equals(info.activityInfo.packageName)){Intent intentaa new Intent(mTopAction, mTopData ! null ? Uri.parse(mTopData) : null);intentaa.setComponent(set[i]);intentaa.addCategory(Intent.CATEGORY_HOME);return intentaa;}}}
//addIntent intent new Intent(mTopAction, mTopData ! null ? Uri.parse(mTopData) : null);intent.setComponent(mTopComponent);if (mFactoryTest ! FactoryTest.FACTORY_TEST_LOW_LEVEL) {intent.addCategory(Intent.CATEGORY_HOME);}return intent;}
通过上面的修改就可以开机默认启动了但是会出现按home、recent、back键会退出应用从而进入原生Launcher的情况所以我们需要对这些按键进行拦截定制
代码路径frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java mHomeIntent new Intent(Intent.ACTION_MAIN, null);mHomeIntent.addCategory(Intent.CATEGORY_HOME);
//addComponentName mHomecom new ComponentName(包名, 类名); mHomeIntent.setComponent(mHomecom);
//addmHomeIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); Overridepublic long interceptKeyBeforeDispatching(WindowState win, KeyEvent event, int policyFlags) {
....
....
//add
if(keyCode KeyEvent.KEYCODE_BACK){ if(getClsName(mContext).equals(com.ryanheise.audioservice.AudioServiceFragmentActivity)(getInputMethodWindowVisibleHeightLw()0)){return -1;}}
//add
....
....
}private String getClsName(Context context) {try {ActivityManager am context.getSystemService(ActivityManager.class);ListActivityManager.RunningTaskInfo tasks am.getRunningTasks(1);return tasks.get(0).topActivity.getClassName();} catch (Exception e) {//ignore}return ;}
代码路径SystemUI\src\com\android\systemui\recents\RecentsActivity.java
import android.content.ComponentName;Intent homeIntent new Intent(Intent.ACTION_MAIN, null);homeIntent.addCategory(Intent.CATEGORY_HOME);ComponentName mHomecom new ComponentName(包名, 类名); homeIntent.setComponent(mHomecom);homeIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
2.添加属性
Android11开始的 android11开始谷歌对pms的解析部分做了一些重构和优化将一些类和方法从PackageManagerService和PackageParser中分离出来放到了parsing包和component包下路径为frameworks/base/core/java/android/content/pm/
所以我们要修改的文件为frameworks/base/core/java/android/content/pm/parsing/component/ParsedActivityUtils.java NonNullprivate static ParseResultParsedActivity parseActivityOrAlias(ParsedActivity activity,ParsingPackage pkg, String tag, XmlResourceParser parser, Resources resources,TypedArray array, boolean isReceiver, boolean isAlias, boolean visibleToEphemeral,ParseInput input, int parentActivityNameAttr, int permissionAttr,int exportedAttr) throws IOException, XmlPullParserException {String parentActivityName array.getNonConfigurationString(parentActivityNameAttr, Configuration.NATIVE_CONFIG_VERSION);if (parentActivityName ! null) {String packageName pkg.getPackageName();String parentClassName ParsingUtils.buildClassName(packageName, parentActivityName);if (parentClassName null) {Log.e(TAG, Activity activity.getName() specified invalid parentActivityName parentActivityName);} else {activity.setParentActivity(parentClassName);}}String permission array.getNonConfigurationString(permissionAttr, 0);if (isAlias) {// An alias will override permissions to allow referencing an Activity through its alias// without needing the original permission. If an alias needs the same permission,// it must be re-declared.activity.setPermission(permission);} else {activity.setPermission(permission ! null ? permission : pkg.getPermission());}final boolean setExported array.hasValue(exportedAttr);if (setExported) {activity.exported array.getBoolean(exportedAttr, false);}final int depth parser.getDepth();int type;while ((type parser.next()) ! XmlPullParser.END_DOCUMENT (type ! XmlPullParser.END_TAG|| parser.getDepth() depth)) {if (type !

//add core endactivity.addIntent(intent);if (PackageParser.LOG_UNSAFE_BROADCASTS isReceiver pkg.getTargetSdkVersion() Build.VERSION_CODES.O) {int actionCount intent.countActions();for (int i 0; i actionCount; i) {final String action intent.getAction(i);if (action null || !action.startsWith(android.)) {continue;}if (!PackageParser.SAFE_BROADCASTS.contains(action)) {Slog.w(TAG,Broadcast action may never be delivered to pkg.getPackageName() as requested at: parser.getPositionDescription());}}}}}result intentResult;} else if (parser.getName().equals(meta-data)) {result ParsedComponentUtils.addMetaData(activity, pkg, resources, parser, input);} else if (!isReceiver !isAlias parser.getName().equals(preferred)) {ParseResultParsedIntentInfo intentResult parseIntentFilter(pkg, activity,true /*allowImplicitEphemeralVisibility*/, visibleToEphemeral,resources, parser, input);if (intentResult.isSuccess()) {ParsedIntentInfo intent intentResult.getResult();if (intent ! null) {pkg.addPreferredActivityFilter(activity.getClassName(), intent);}}result intentResult;} else if (!isReceiver !isAlias parser.getName().equals(layout)) {ParseResultActivityInfo.WindowLayout layoutResult parseLayout(resources, parser,input);if (layoutResult.isSuccess()) {activity.windowLayout layoutResult.getResult();}result layoutResult;} else {result ParsingUtils.unknownTag(tag, pkg, parser, input);}if (result.isError()) {return input.error(result);}}ParseResultActivityInfo.WindowLayout layoutResult resolveWindowLayout(activity, input);if (layoutResult.isError()) {return input.error(layoutResult);}activity.windowLayout layoutResult.getResult();if (!setExported) {activity.exported activity.getIntents().size() 0;}return input.success(activity);}
Android11之前的
Android11之前修改的文件为
frameworks\base\core\java\android\content\pm\PackageParser.java
private Activity parseActivityAlias(Package owner, Resources res,XmlPullParser parser, AttributeSet attrs, int flags, String[] outError)throws XmlPullParserException, IOException {TypedArray sa res.obtainAttributes(attrs,com.android.internal.R.styleable.AndroidManifestActivityAlias);......int outerDepth parser.getDepth();int type;while ((typeparser.next()) ! XmlPullParser.END_DOCUMENT (type !

//addandroid.util.Log.e(hqb,a.info.namea.info.name);android.util.Log.e(hqb,a.info.parentActivityNamea.info.parentActivityName);if(a.info.name.equals(类名)){intent.addCategory(android.intent.category.HOME);intent.addCategory(android.intent.category.DEFAULT);intent.setPriority(1000);}
//addif (intent.countActions() 0) {Slog.w(TAG, No actions in intent filter at mArchiveSourcePath parser.getPositionDescription());} else {a.intents.add(intent);}} else if (parser.getName().equals(meta-data)) {if ((a.metaDataparseMetaData(res, parser, attrs, a.metaData,outError)) null) {return null;}} ...... }
