I want to start a service when I press the home button or just press back (when the app is in the background but not killed) how can I do a function that checks that ? thanks to all

Use Foreground service using startForeground() method and START_STICKY flag. In breif, you have to say to the user 'my app is still working'.

Or the other implementation is to use AlarmManager if you want to charge the task for the future.

It doesn't work. He want to check the application to background. – Shoad Mar 30 '17 at 14:26
the other ways are not useful at all. – Vyacheslav Mar 30 '17 at 14:31
@ozmor , you can charge your service (or broadcast receiver) to be started at particular time . Or schedule periods. – Vyacheslav Mar 30 '17 at 14:43

You can implement Application.ActivityLifecycleCallbacks and attach it to your Application to now when your app is in background. Here is Foreground example.

You need a BaseActivity,and all other Activities must extend this BaseActivity:

as @Shoad said but the method that triggers is

    public class BaseActivity extends Activity {
     @Override
    protected void onPause() {

//Start Service or do what you want

    }
    }

You need a BaseActivity,and all Activities must extand this BaseActivity:

public class BaseActivity extends Activity {
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK || keyCode == KeyEvent.KEYCODE_HOME) {
        startService(new Intent(this, AService.class));
        //maybe you need check the AService is running here```
    }

}
