禁止某个app通过开机广播自启动，覆盖住Launcher

代码位置 :

frameworks/base/services/core/java/com/android/server/am/ActivityManagerService.java

具体修改如下

public final int startActivityAsUser(IApplicationThread caller, String callingPackage,Intent intent, String resolvedType, IBinder resultTo, String resultWho, int requestCode,int startFlags, ProfilerInfo profilerInfo, Bundle bOptions, int userId,boolean validateIncomingUser) {enforceNotIsolatedCaller("startActivity");// for disable MQlAUNCHER begin  开始if (isMoreLauncherConfig()) {Log.d("youdianxs", "MQ CONFIG");try{ActivityInfo aInfo = resolveActivityInfo(intent, STOCK_PM_FLAGS, userId);Log.d("youdianxs", "callingPackage = " + callingPackage);Log.d("youdianxs", "callingPackageactivity = " + aInfo.taskAffinity);//判断包名if (MQ_PACKAGE.equals(callingPackage)){Log.d("youdianxs", "MQ START===" + isProhibitLauncherTime());if (isProhibitLauncherTime() && isNoMqLauncher()) {Log.d("youdianxs", "MQ lanjie");//核心代码  所有条件成立start cancelreturn ActivityManager.START_CANCELED;}}}catch(Exception e){Log.d("youdianxs", "e.getMessage = " + e.getMessage());}}// for disable MQlAUNCHER end   结束userId = mActivityStartController.checkTargetUser(userId, validateIncomingUser,Binder.getCallingPid(), Binder.getCallingUid(), "startActivityAsUser");// TODO: Switch to user app stacks here.return mActivityStartController.obtainStarter(intent, "startActivityAsUser").setCaller(caller).setCallingPackage(callingPackage).setResolvedType(resolvedType).setResultTo(resultTo).setResultWho(resultWho).setRequestCode(requestCode).setStartFlags(startFlags).setProfilerInfo(profilerInfo).setActivityOptions(bOptions).setMayWait(userId).execute();}//判断是否开机前十分钟之内private boolean isProhibitLauncherTime() {Log.d("youdianxs", "MQ time====" + (SystemClock.elapsedRealtime() / 1000 / 60));return (SystemClock.elapsedRealtime() / 1000 / 60) <= 10;}//判断此Activity是不是默认Launcherprivate boolean isNoMqLauncher() {final ArrayList<ResolveInfo> homeActivities = new ArrayList<>();ComponentName currentDefaultHome = mContext.getPackageManager().getHomeActivities(homeActivities);if (currentDefaultHome != null) {Log.d("youdianxs", "currentDefaultHome.flattenToString()====" + currentDefaultHome.flattenToString());return !currentDefaultHome.flattenToString().equals(MQ_PACKAGE + "/" + MQ_ACTIVITY);}return true;}//判断配置成立private boolean isMoreLauncherConfig() {return SvtGeneralProperties.getBoolProperty("SVT_ZC_MORE_HOME_CONFIG");}

总结 条件成立时 --------> return ActivityManager.START_CANCELED;
