应用程序进程终止后无法单击 Android 小部件

Question

我编写了一个带有两个按钮的 Android 小部件。如果我启动 "Activity" 一切正常，我可以单击这些按钮。但是如果我锁定 phone，进程会在几秒后终止

然后我尝试再次单击这些按钮，没有任何反应，除了 LOGCAT：

I/ActivityManager: filter receiver for action = ButtonRefresh

updateAppWidget，通过 @Override onUpdate(...):

调用

private final static String BUTTON_REFRESH = "ButtonRefresh";

public static void updateAppWidget(final Context context, final AppWidgetManager appWidgetManager,
                                   final int appWidgetId) {

    final RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.myclasslayout);

    //Click listener depending on @this (getPendingSelfIntent)
    views.setOnClickPendingIntent(R.id.button_refresh, getPendingSelfIntent(context, BUTTON_REFRESH));

    [...]

    appWidgetManager.updateAppWidget(appWidgetId, views);
}

getPendingSelfIntent():

private static PendingIntent getPendingSelfIntent(Context context, String action) {
    Intent intent = new Intent(context, MyClass.class);
    intent.setAction(action);
    return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}

onReceive():

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);

    if (BUTTON_REFRESH.equals(intent.getAction())) {
        Log.i("MyLogtag", "Refresh"); //This never shows up in LOGCAT
    }
}

AndroidManifest.xml:

[...]
<receiver android:name=".MyClass">
    <intent-filter>
        <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
    </intent-filter>
    <meta-data
        android:name="android.appwidget.provider"
        android:resource="@xml/myclass_info" />
</receiver>
[...]

onReceive never 在应用进程 dead...

时被调用

Answer 1

我明白了...

我必须改变

private final static String BUTTON_REFRESH = "ButtonRefresh";

到

private final static String BUTTON_REFRESH = "com.example.mypackage.BUTTON_REFRESH";

和AndroidManifest:

 <receiver android:name=".MyClass">
<intent-filter>
    <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
    <action android:name="com.example.mypackage.BUTTON_REFRESH"/>
</intent-filter>
<meta-data
    android:name="android.appwidget.provider"
    android:resource="@xml/myclass_info" />
</receiver>
