A应用

package visizen.com.a;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    private Button btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btn = (Button) this.findViewById(R.id.button);

    }


    public void broadCast(View view) {
        Intent intent = new Intent();
        intent.setAction("a");
        //无序
        //sendBroadcast(intent);

        //有序
       //sendOrderedBroadcast(intent,null);

        //最终都会有一个接收者接收消息
        sendOrderedBroadcast(intent,null,new FinalReceiver(),null,0,null,null);
    }
}
