Myujth

I am trying to be able to make an aspect of my application lock other apps should they visited, using the code I have seen from the sites below. My issue here is that the app is not detecting other apps that I have opened and only outputs com.sec.android.app.launcher when I have not got the main lock application open. I have used the permission below as the others found were depreciated. Atm I understand that my program will only go to the lockscreen activity should I be on my lock app but if I change that to another package it doesnt work.

I have used these links and various others to try remedy the situation but am quite stuck, I dont understand what I am doing wrong.

Android lock application

Blocking android apps programmatically

 <uses-permission xmlns:tools="http://schemas.android.com/tools"

 public class MyService extends Service{
CountDownTimer check;
@Override
public IBinder onBind(Intent arg0) 
 return null;


public void heh()
 check = new CountDownTimer(5000, 5000) 
 @Override
 public void onTick(long millisUntilFinished) 
 //Do nothing here

 

 @Override
 public void onFinish()

 Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
 mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
 List<ResolveInfo> appList = packageManager.queryIntentActivities(mainIntent, 0);
 Collections.sort(appList, new ResolveInfo.DisplayNameComparator(packageManager));
 List<PackageInfo> packs = packageManager.getInstalledPackages(0);
 for (int i = 0; i < packs.size(); i++) 
 PackageInfo p = packs.get(i);
 ApplicationInfo a = p.applicationInfo;
 if ((a.flags & ApplicationInfo.FLAG_SYSTEM) == 1) 
 continue;
 
 // skip system apps if they shall not be included

 

 ActivityManager mActivityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
 List<ActivityManager.RunningTaskInfo> RunningTask = mActivityManager.getRunningTasks(1);
 // List<ActivityManager.RunningAppProcessInfo> RunningApp = mActivityManager.getRunningAppProcesses();
 // ActivityManager.RunningAppProcessInfo apr = RunningApp.get(0);
 ActivityManager.RunningTaskInfo ar = RunningTask.get(0);
 String activityOnTop = ar.topActivity.getPackageName();
 // String activityOnTops = apr.processName;
 Toast.makeText(MyService.this, "Activity is: " + activityOnTop, Toast.LENGTH_LONG).show();
 if (activityOnTop.contains("com.example.heh.lock")) 

 Intent lockIntent = new Intent(MyService.this, LockScreen.class);
