Answer 1

Check if your app is running then only abort broadcast receiver else not

//define this variable above onReceive() with default value as false;
boolean appRunningInBack=false;

ActivityManager am = (ActivityManager) mContext.getSystemService(Activity.ACTIVITY_SERVICE);
String packageName = am.getRunningTasks(1).get(0).topActivity.getPackageName();

if(packageName.equalIgnoreCase("your app package name") || appRunningInBack)
{    
    appRunningInBack=true;
    abortBroadCast();
} else {

}

Also add Permission in AndroidManifest.xml

<uses-permission android:name="android.permission.GET_TASKS" />

After this when your app goes in background.or while running .this variable will be true.
