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 :

powershell 复制代码

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

具体修改如下

java 复制代码

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");
    }

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