Android Lollipop Sends Multiple BroadcastReceivers for Telephone State Changes

Question

Up to android kitkat phone state broadcast receiver works fine. In android lolipop phone state broadcast receiver sending multiple broadcast. Is there any thing changed in Android Lolipop.

public class PhoneStateBroadcastReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
    String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
    Log.d("PhoneState", state);
  }
 }  
} 

  <receiver android:name="com.phonestate.PhoneStateBroadcastReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
    </receiver>

i noticed there is an extra sent with the intent called subscription, and seems to be either 1 or 9223372036854775807. My guess is, a bug? — gerfmarquez, Feb 24 '15 at 16:51
the number is Long.MAX_VALUE. Have you find why this is happening? — Muzikant, Mar 25 '15 at 11:14

It gets worse... with the Android 5.1 update the `subscription` extra is now Integer and gets the value of Integer.MAX_VALUE (2147483647) — Muzikant, Apr 14 '15 at 06:47

I would recommend this solution:

public void onReceive(Context context, Intent intent) {
  long subId = intent.getLongExtra("subscription", Long.MIN_VALUE);
  if(subId < Integer.MAX_VALUE) {
    // hurray, this is called only once on all operating system versions!
  }
}

it works on both 4.x a 5.x and should be forward-compatible. For more details please refer to my blog:
