android - 每次在三星设备上更新应用程序时小部件都会消失

Question

我的应用程序中有 2 个小部件。两者具有完全相同的功能，但布局不同。它们在每台设备上都运行良好，但在三星设备上似乎存在问题。每次我发布新版本的应用程序时，小部件都会从用户屏幕上删除。看起来这是一个 Samsung TouchWiz 错误，但用户告诉我其他应用程序没有这个问题。知道发生了什么事吗？

顺便说一句，我想了一下，我在这篇博文中找到了修复它的方法:https://medium.com/the-wtf-files/the-mysterious-case-of-the-disappearing-widget-f4177a8e2c2b但我没有手动调用

updateIntent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);

我调用

ComponentName cn = new ComponentName(context, clazz); AppWidgetManager.getInstance(context).updateAppWidget(cn, views);

更多我的代码:

    public static final int layout = R.layout.widget_large_layout;
    public static final BitmapQualityEnum thumbnailQuality = BitmapQualityEnum.HIGH_RES;
    public static final Class<?> clazz = LargeWidgetProvider.class;

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        if (context != null && appWidgetIds != null && appWidgetIds.length > 0) {
            // To prevent any ANR timeouts, we perform the update in a service
            context.startService( new Intent(context, LargeWidgetProvider.UpdateService.class));
        }
    }


    @Override
    public void onReceive(Context context, Intent intent) {
        if (context != null && intent != null) {
            boolean doUpdate = true;
            if ("android.appwidget.action.APPWIDGET_UPDATE".equals(intent.getAction())) {
                final int[] widgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);
                doUpdate = (widgetIds != null && widgetIds.length > 0);
            }

            if (doUpdate) {
                WidgetProviderHelper.receive(context, intent, clazz, layout, thumbnailQuality);
            }
            super.onReceive(context, intent);
        }
    }

public static class UpdateService extends Service {

        private int serviceStartId = -1;

        @Override
        public boolean onUnbind(Intent intent) {
            stopSelf(this.serviceStartId);
            return true;
        }

        @Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            this.serviceStartId = startId;
            // Push update for this widget to the home screen
            updateData(this);
            return START_STICKY;
        }

        @Override
        public void onConfigurationChanged(Configuration newConfig) {
            super.onConfigurationChanged(newConfig);
            //          int oldOrientation = this.getResources().getConfiguration().orientation;
            //          if (newConfig.orientation != oldOrientation) {
            // Update the widget) {
            updateData(this);
            //          }
        }


        @Override
        public IBinder onBind(Intent intent) {
            // We don't need to bind to this service
            return null;
        }
    }

我终于设法解决了我的问题。小部件提供者接收器需要导出!!

    <receiver
        android:name=".widget.HorizontalWidgetProvider"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
            <action android:name="com.customEvent" />
        </intent-filter>

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