2)Dynamic Registration

B

Answer 1

I am going to show you difference static and dynamic broadcast receivers via coding:

a) Define UI for both kind of receviers:

b) DynamicBroadcastReceiver.java

 public class DynamicBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Toast.makeText(context, "Dynamic Broadcast", Toast.LENGTH_SHORT).show();
}

}

c) StaticBroadcastReceiver.java

public class StaticBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Toast.makeText(context, "Static Broadcast", Toast.LENGTH_SHORT).show();
}

}

d) MainActivity.java

 public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
//////////////////=================Starts Dynamic Broadcast Receiver
DynamicBroadcastReceiver dynamicBroadcastReceiver = new DynamicBroadcastReceiver();

public void registerBroadcastReceiverDynamically(View view) {
    IntentFilter filter = new IntentFilter();
    filter.addAction("MY_BROADCAST");
    registerReceiver(dynamicBroadcastReceiver, filter);
}

public void sendUsingDynamicallyRegisteredBroadcastReceiver(View view) {
    Intent i = new Intent();
    i.setAction("MY_BROADCAST");
    sendBroadcast(i);
}

@Override
protected void onDestroy() {
    if (dynamicBroadcastReceiver != null) {
        unregisterReceiver(dynamicBroadcastReceiver);
    }
    super.onDestroy();
}

//////////////////=================Ends Dynamic Broadcast Receiver


//////////////////=================Starts Static Broadcast Receiver
public void sendUsingStaticallyRegisteredBroadcastReceiver(View view) {
    Intent i = new Intent();
    i.setAction("MY_BROADCAST_STATIC");
    sendBroadcast(i);
}

}

e) Manifest File:
