Android app接收来自adb发送的广播的实例学习

Android app接收来自adb发送的广播的实例学习

简单介绍：通过命令行执行adb shell am broadcast发送广播通知。

adb shell am broadcast 后面的参数有：


[-a ]
[-d ]
[-t ] 
[-c [-c ] ...] 
[-e|--es ...] 
[--ez ...] 
[-e|--ei ...] 
[-n ]
[-f ] []


例如：
adb shell am broadcast -a com.android.test --es test_string "this is test string" --ei test_int 100 --ez test_boolean true


说明：蓝色为key，红色为alue，分别为String类型，int类型，boolean类型

一、app 主要代码

1、MainActivity.java

package com.example.receiverbroadcastsendbyadb;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

public class MainActivity extends Activity {
	private TextView Recevier_Text;
	 private final BroadcastReceiver mReceiverBroadCast = new BroadcastReceiver() {
	      @Override
	      public void onReceive(Context context, Intent intent) {
	      	   String msg = intent.getStringExtra("msg");  
	           Recevier_Text.setText("great!Received a Broadcast! "+"msg="+msg);
	      } 
	  };

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		IntentFilter filter = new IntentFilter(); 
		filter.addAction("android.intent.action.BROADCAST_FORM_ADB");
		Recevier_Text=(TextView)findViewById(R.id.textView1);
		Recevier_Text.setText("wait a Broadcast.....");
		registerReceiver(mReceiverBroadCast, filter);
		
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle action bar item clicks here. The action bar will
		// automatically handle clicks on the Home/Up button, so long
		// as you specify a parent activity in AndroidManifest.xml.
		int id = item.getItemId();
		if (id == R.id.action_settings) {
			return true;
		}
		return super.onOptionsItemSelected(item);
	}
}

2、AndroidManifest.xml代码

二、执行

1、运行app，中间的文本显示等待接收adb发过来的广播。

2、执行adb shell am broadcast -a  android.intent.action.BROADCAST_FORM_ADB   --es msg "i love tanghanyue"

3、执行上面的命令后：

 4、测试结果接收到adb发过来的广播。

三，当然可以发送系统广播等，例如亮屏广播adb shell am broadcast -a Intent.ACTION_SCREEN_ON，然后在接收端接收这个广播就可以，测试ok。
