Android中使用命令 adb shell am broadcast 發(fā)送廣播。

代碼：

注冊(cè)一個(gè)廣播接收器，用來監(jiān)聽廣播，如果收到了自己監(jiān)聽到的廣播，則打印一條log：

public class MyBroadcastReceiverextends BroadcastReceiver {
    
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("MyBroadcastReceiver","onReceive: start...");
        throw new UnsupportedOperationException("Not yet implemented");
    }
}

監(jiān)聽的廣播內(nèi)容在AndroidManifest.xml設(shè)置：
讓廣播接收器MyBroadcastReceiver去監(jiān)聽一條com.chen.broadcasttest.MY_BROADCAST的廣播

        <receiver
            android:name=".MyBroadcastReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="com.chen.broadcasttest.MY_BROADCAST"/>
            </intent-filter>
        </receiver>

MainActivity只打印一條log

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.d("MainActivity", "starts...");
    }
}

啟動(dòng)app后，在cmd中輸入

adb shell am broadcast -a com.chen.broadcasttest.MY_BROADCAST com.chen.broadcasttest

其中參數(shù) -a表示action;
com.chen.broadcasttest.MY_BROADCAS是廣播接收器想要監(jiān)聽的廣播名稱
com.chen.broadcasttest是app的包名。在我的環(huán)境中，不加入包名則無法發(fā)送廣播，不知道為什么。

執(zhí)行：

C:\Users\chen>adb shell am broadcast -a com.chen.broadcasttest.MY_BROADCAST com.chen.broadcasttest
Broadcasting: Intent { act=com.chen.broadcasttest.MY_BROADCAST flg=0x400000 pkg=com.chen.broadcasttest }
Broadcast completed: result=0

Android Studio中l(wèi)ogcat的結(jié)果：
