关闭广播接收器中的活动

Question

I have a broadcast receiver to check the internet connectivity, in which i have validated if no internet connection I am displaying an error screen through intent. Now i need to close the error screen when the network is reconnected and display the previous screen from which the network was gone.

private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        isConnected = intent.getBooleanExtra(ConnectionDetector.CONNECTED_KEY, false);
        if(isConnected){
            System.out.println("A1");
            finish();
        }
        if (intent.getAction().equals(CONNECTION_BROADCAST_ACTION)) {
            System.out.println("A2");
            No_Network.this.finish();
        }
    }
};

This is my code inside the error screen activity. How to close the activity here? finish() is not working.

How to close the activity here? finish() is not working

It is "not working" because you are not using it correctly. The correct approach is to notify the activity and tell it to finish() itself. You can do that by sending intent with "magic" code of yours directly to your activity (if it is in singleTop launch mode then startActivity() + onNewIntent() would suffice). Alternatively use event bus for communication.
