Android Lock Application

Im trying to make an app that Locks all applications with a password because 'Kiosk Mode' cant be done as you can see in my question here ( disabling and hiding android navigation

Solution 1:

First of all , if your service isn't even starting , then check in AndroidManifest.xml for this

<serviceandroid:name=".MyService"android:enabled="true" />

If it's starting then from what i understand , you are checking which apps are running when your service is started.

For now , just to test your code , implement an CountDownTimer , Which will check TOP Activity every 5 Second like

Protected CountDownTimercheck=newCountDownTimer(5000, 5000)
        {

            @OverridepublicvoidonTick(long millisUntilFinished)
            {
                //Do nothing here

            }

            @OverridepublicvoidonFinish()
            {
                PackageManagerpackageManager= getPackageManager();
                IntentmainIntent=newIntent(Intent.ACTION_MAIN, null);
                mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
                List<ResolveInfo> appList = packageManager.queryIntentActivities(mainIntent, 0);
                Collections.sort(appList, newResolveInfo.DisplayNameComparator(packageManager));
                List<PackageInfo> packs = packageManager.getInstalledPackages(0);
                for(int i=0; i < packs.size(); i++) 
                {
                    PackageInfop= packs.get(i);
                    ApplicationInfoa= p.applicationInfo;
                    // skip system apps if they shall not be included//apps.add(p.packageName);
                }   

                ActivityManagermActivityManager= (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
                List<ActivityManager.RunningTaskInfo> RunningTask = mActivityManager.getRunningTasks(1);
                ActivityManager.RunningTaskInfoar= RunningTask.get(0);
                StringactivityOnTop= ar.topActivity.getClassName();


                if(!activityOnTop.equals("com.example.lock"))
                {
                    IntentlockIntent=newIntent(this, LockScreen.class);
                    lockIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    this.startActivity(lockIntent);
                }
                this.cancel();
                this.start();
           }
};

Don't forget to start the countdowntimer from onCreate of service

check.start();
