How can I determine permission of Running apps programmatically in android?

Question

I want to see the permission of running apps of android in my software.

For this reason ,I have the following code :

   List<App> apps = new ArrayList<App>();
   ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);

   PackageManager packageManager = getPackageManager();

   List<RunningAppProcessInfo> l = am.getRunningAppProcesses();
   Iterator<RunningAppProcessInfo> i = l.iterator();

   PackageManager pm = this.getPackageManager();
   int row_count = 0 ;

   while(i.hasNext()) {
     ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
     try 
     {
       CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
       App app = new App();
       app.setTitle(c.toString());
       app.setPackageName(l.get(row_count).processName);

       PackageInfo packageInfo =  packageManager.getPackageInfo(l.get(row_count).processName, PackageManager.GET_PERMISSIONS);
       String[] reqPermission= packageInfo.requestedPermissions;
       app.set_Permission_Info(reqPermission);

    //   app.setVersionName(p.versionName);
     //  app.setVersionCode(p.versionCode);
      // CharSequence description = p.applicationInfo.loadDescription(packageManager);
     //  app.setDescription(description != null ? description.toString() : "");
       row_count++;
       // app.setSize(p.s)
       apps.add(app);

     }

     catch(Exception e){}

But there is a problem.

When I run my apps ,I find that the app name and app's package name are not consistent . Why has this problem introduced?

The main problem is described follow:

Let us suppose an apps named "EBOOK_Reader" and "Camera" is running in my device . The package name is "com.a.b" and "com.c.d" respectively. The problem of this code is the appropriate package name is not with appropriate apps name .

It shows the package name Of "com.a.b" to "Camera " and "com.c.d" to "EBOOK_Reader" which is not desired .

Any idea of how can the problem be solved? ThankYou

The app name and app's package name are normally different. You better use the package name as this is unique throughout the device.

Update: Now I understand your problem. Thanks for clarifying. It is because of the variable row_count. Basically you're are using two different iterator variables. That's why your getting 2 different results. You don't need row_count because you already have interator for i. Try the updated code below:

Basically l.get(row_count).processName was replaced by info.processName.

List<App> apps = new ArrayList<App>();
   ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);

   PackageManager packageManager = getPackageManager();

   List<RunningAppProcessInfo> l = am.getRunningAppProcesses();
   Iterator<RunningAppProcessInfo> i = l.iterator();

   PackageManager pm = this.getPackageManager();
   // int row_count = 0 ; // no need for this. feel free to delete

   while(i.hasNext()) {
     ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
     try 
     {
       CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
       App app = new App();
       app.setTitle(c.toString());
       app.setPackageName(info.processName);

       PackageInfo packageInfo =  packageManager.getPackageInfo(info.processName, PackageManager.GET_PERMISSIONS);
       String[] reqPermission= packageInfo.requestedPermissions;
       app.set_Permission_Info(reqPermission);

    //   app.setVersionName(p.versionName);
     //  app.setVersionCode(p.versionCode);
      // CharSequence description = p.applicationInfo.loadDescription(packageManager);
     //  app.setDescription(description != null ? description.toString() : "");
       //row_count++; // no need for this. feel free to delete
       // app.setSize(p.s)
       apps.add(app);

     }

     catch(Exception e){}
