Checking by code whether android app is foreground or background on device

Question

I wants to determine whether my app is in foreground or background on device. In my app, When i get push notification on device then it is require to me that identify 1. whether app is in background or foreground? 2. What is/was the current/last opened activity of app.

and one more thing, I also wants to find out the check box value(checked/unchecked) of "show notifications" checkbox of app setting(find it by going setting->app manager->select my app from list). According to the value of this checkbox, different code will execute in my app.

Yours help is appreciated,

Thanking you.

You can use the method onwindowFocusChanged() to determine whether your window (activity) gained (foreground) or lost (background) focus. This is the function:

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    // TODO Auto-generated method stub
    super.onWindowFocusChanged(hasFocus);

//write your code here

}

You can add this to your activities

public boolean IsAppForeground(Context context){

ActivityManager activityManager = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE); List appProcesses = activityManager.getRunningAppProcesses(); if (appProcesses == null){ return false; } final String packageName = context.getPackageName(); for (RunningAppProcessInfo appProcess : appProcesses) { if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals(packageName)) { return true; } }return false; }
