I have gone through this question and this question. But with the help of this library i can now get the list of foreground tasks using following code.
if (B
The "apps with usage accesse" feature sometimes can meet your needs
So here is an update. Tested in 5.0 and 5.1.1 device. Working perfectly.
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) { //For versions less than lollipop
ActivityManager am = ((ActivityManager) getSystemService(ACTIVITY_SERVICE));
List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(5);
top = taskInfo.get(0).topActivity.getPackageName();
Log.v(TAG, "top app = " + top);
}else{ //For versions Lollipop and above
List<AndroidAppProcess> processes = ProcessManager.getRunningForegroundApps(getApplicationContext());
Collections.sort(processes, new ProcessManager.ProcessComparator());
for (int i = 0; i <=processes.size()-1 ; i++) {
if(processes.get(i).name.equalsIgnoreCase("com.google.android.gms")) { //always the package name above/below this package is the top app
if ((i+1)<=processes.size()-1) { //If processes.get(i+1) available, then that app is the top app
top = processes.get(i + 1).name;
} else if (i!=0) { //If the last package name is "com.google.android.gms" then the package name above this is the top app
top = processes.get(i - 1).name;
} else{
if (i == processes.size()-1) { //If only one package name available
top = processes.get(i).name;
}
}
Log.v(TAG, "top app = " + top);
}
}
}
Thanks to this library
Now i'm able to get foreground task in Android 5.0+
