java - 为了捕获 BOOT_COMPLETED，只需在 `AndroidManifest.xml` 中注册 BroadcastReceiver 就足够了吗？

Question

为了抓android.intent.action.BOOT_COMPLETED事件，只注册 BroadcastReceiver 就够了吗？在 AndroidManifest.xml ？像这样:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.myDomain.myApp"
          android:installLocation="internalOnly">
    <!-- ... stuff ... -->
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <!-- ... stuff ... -->
    <application ...>
        <!-- ... stuff ... -->
        <receiver android:name=".bgServices.MyBootBroadcastReceiver">
        </receiver>
        <!-- ... stuff ... -->
    </application>
</manifest>

BroadcastReceiver :

package com.myDomain.myApp.bgServices;

// imports ...

public class MyBootBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("my-log", "MyBootBroadcastReceiver.onReceive()");
        Toast.makeText(context, "YEAY!", Toast.LENGTH_LONG).show();    
    }
}

我问是因为我要发送:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -n com.myDomain.myApp/.bgServices.MyBootBroadcastReceiver

但是什么也没发生。

(我运行应用程序，而不仅仅是将其推送到设备)

Answer 1

将以下 IntentFilter 添加到您的 BroadcastReceiver:

<receiver android:name=".bgServices.MyBootBroadcastReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <action android:name="android.intent.action.QUICKBOOT_POWERON" />
    </intent-filter>
</receiver>

虽然 android.intent.action.BOOT_COMPLETED 应该足够了，但似乎有些设备还需要 android.intent.action.QUICKBOOT_POWERON。

有关更多信息，您应该查看developer's guide在 Intent 和 IntentFilter 上。
