Question

我创建了一个Android小部件在运行Android 4.4.4的Genymotion Nexus 4模拟器中，一切运行良好在运行Android 4.4.4的Nexus 4设备上，我将小部件放在主屏幕上，然后变成了Google App小部件然后它变成我的小部件，然后再次进入Google App小部件，依此类推。在我从主屏幕中删除小部件之前，它会执行此操作此外，我使用parse.com作为在线存储，在我的手机上似乎没有获得数据。我无法确定，因为小部件不断变化我的小部件包含3个文件扩展应用程序类的一个：

public class MyApp extends Application
{
    private MyModel model;

     @Override
    public void onCreate() {
        Parse.enableLocalDatastore(this);
        ParseObject.registerSubclass(GdbdData.class);
        Parse.initialize(this, "-", "-");

        if(model == null) {
            Intent intent = new Intent(this,GdbdWidgetProvider.class);
            intent.setAction(WidgetUtils.WIDGET_REFRESH_STORAGE);
            intent.putExtra("userId",123);
            sendBroadcast(intent);
        }

        super.onCreate();
    }

一个WidgetProvider：

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);
    final String action = intent.getAction();
    if (action.equals(WidgetUtils.WIDGET_REFRESH_STORAGE))
    {
        MyApp app = ((MyApp)context.getApplicationContext());
        int userId = intent.getIntExtra("userId",0);
        TryGetModelFromRemoteStorage(userId,context);
    }

}


static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId)
{
    MyApp app = ((MyApp)context.getApplicationContext());
    MyModel model = app.getModel();

    // Construct the RemoteViews object
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.the_widget);

    PendingIntent clickerPendingIntent = buildButtonPendingIntent(context);

    // I change some textviews and imageviews inside the widget here

    appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
}

public static PendingIntent buildButtonPendingIntent(Context context) {

    // initiate widget update request
    Intent intent = new Intent();
    intent.setAction(WidgetUtils.WIDGET_UPDATE_ACTION);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
    return pendingIntent;
}

一个处理窗口小部件按钮的广播接收器：

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(WidgetUtils.WIDGET_UPDATE_ACTION)) {
        updateWidget(context);
    }
}

private void updateWidget(Context context) {


    MyApp app = ((MyApp)context.getApplicationContext());
    MyModel model = app.getModel();

    //I update some fields in the model based on some business rules at this point

    MyWidgetProvider.SendUpdateMessageToWidgets(context);


}

有谁知道我做错了什么？

编辑1：按要求添加清单文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.my.app.main" >

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:name="MyApp"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <receiver android:name=".GdbdWidgetProvider" >
            <intent-filter>
                <action android:name="android.appwidget.action.APPWIDGET_ENABLED" />
                <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />

            </intent-filter>

            <meta-data
                android:name="android.appwidget.provider"
                android:resource="@xml/the_widget_info" />
        </receiver>
        <receiver
            android:name=".TapMarkDayIntentReceiver"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="com.my.app.intents.UPDATE_WIDGET" />
            </intent-filter>

            <meta-data
                android:name="android.appwidget.provider"
                android:resource="@xml/the_widget_info" />
        </receiver>
    </application>

</manifest>

编辑2，添加了widget xml文件：

  <?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
    android:minWidth="140dp" android:minHeight="140dp"
    android:updatePeriodMillis="1000000"
    android:previewImage="@drawable/example_appwidget_preview"
    android:initialLayout="@layout/the_widget" android:widgetCategory="home_screen"
    android:initialKeyguardLayout="@layout/the_widget"></appwidget-provider>

Answer 1

很抱歉没有回答最后的评论，但我真的很忙感谢大家的帮助。
发生的事情是我在WidgetProvider的onUpdate，onEnabled，onDisabled和orReceive方法中返回了语句，显然这是一件坏事。一旦我删除它们就不再发生了。

Android小部件在模拟器中运行良好，但在手机上它变成了Google App小部件
