Android9禁止某个app启动

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
1

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 cancel
					return 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Launcher
    private 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");
    }
