Android部件停止工作随机 [英] Android Widget stops working randomly

问题描述

我一直在努力解决这个问题了三天，现在我已经看了每一个问题就在这里的回答。我上有一个按钮，一个小部件，所有我想它做的是启动服务每次被点击。问题是，该按钮停止工作随机。在所有我能不能重新创建它，我不知道是什么原因造成的。我的服务电话stopSelf（）;但我有这个问题，一个广播接收器也，所以我认为是在小部件，而不是在服务的问题。这里是code

 公共无效的OnUpdate（上下文的背景下，AppWidgetManager appWidgetManager，INT [] appWidgetIds）
{

Log.i（小部件，的onupdate）;

最终诠释N = appWidgetIds.length;

    的for（int i = 0; I＆n种;我++）
    {

        INT appWidgetId = appWidgetIds [I]

        Log.i（小部件，onUpdateLoop）;


        意向意图=新的意图（背景下，ServiceWidgetAction.class）;
        intent.setAction（Long.toString（System.currentTimeMillis的（）））;
        intent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;

        PendingIntent pendingIntent = PendingIntent
                .getService（背景下，0，意向，PendingIntent.FLAG_UPDATE_CURRENT）;

        RemoteViews意见=新RemoteViews（context.getPackageName（）
               R.layout.widget）;

        views.setOnClickPendingIntent（R.id.widgetButton，pendingIntent）;

        views.setTextViewText（
                R.id.widgetTextView，
                一些文本）;

        appWidgetManager.updateAppWidget（appWidgetId，意见）;

    }

}
 

我检查这个code一遍又一遍，我不知道为什么它是这样做的。它这样做是在3个不同的手机，我不能重新创建它。我试过力停止的应用程序，从任务管理器清除它添加新部件等，以获得部件停止工作，也不会。但是今天早上当我醒来的小工具不再有效。任何帮助将不胜AP preciated。

解决方案

我最终找出问题

。我正在更新从其他地方的小部件的应用程序，我没有完整的code的每一个。换句话说我的应用程序更新textviews在这样的小部件

  RemoteViews意见=新RemoteViews（context.getPackageName（）
           R.layout.widget）;

    views.setTextViewText（
            R.id.widgetTextView，
            一些文本）;

    appWidgetManager.updateAppWidget（appWidgetId，意见）;
 

但它需要整个code保持注册这样的按钮：

 意向意图=新的意图（背景下，ServiceWidgetAction.class）;
    intent.setAction（Long.toString（System.currentTimeMillis的（）））;
    intent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;

    PendingIntent pendingIntent = PendingIntent
            .getService（背景下，0，意向，PendingIntent.FLAG_UPDATE_CURRENT）;

    RemoteViews意见=新RemoteViews（context.getPackageName（）
           R.layout.widget）;

    views.setOnClickPendingIntent（R.id.widgetButton，pendingIntent）;

    views.setTextViewText（
            R.id.widgetTextView，
            一些文本）;

    appWidgetManager.updateAppWidget（appWidgetId，意见）;
 

每当你从你的应用程序中更新部件，确保它看起来酷似code在小部件本身那么底线是。不要留下任何东西了。

I have been working with this problem for three days now and I've looked at every single question on here for an answer. I have a widget with a button on it and all I would like it to do is start a service everytime it is clicked. The problem is that the button stops working randomly. I can't recreate it at all and I have no idea what causes it. My service calls stopSelf(); but I have had this problem with a broadcast receiver also so I believe the problem to be in the widget and not in the service. Here is the code

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[]     appWidgetIds) 
{

Log.i("Widget", "onUpdate");

final int N = appWidgetIds.length;

    for (int i=0; i<N; i++) 
    {

        int appWidgetId = appWidgetIds[i];

        Log.i("Widget", "onUpdateLoop");


        Intent intent = new Intent(context, ServiceWidgetAction.class);
        intent.setAction(Long.toString(System.currentTimeMillis()));
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        PendingIntent pendingIntent = PendingIntent
                .getService(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

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

        views.setOnClickPendingIntent(R.id.widgetButton, pendingIntent);

        views.setTextViewText(
                R.id.widgetTextView,
                "Some text");

        appWidgetManager.updateAppWidget(appWidgetId, views);

    }

}

I've checked this code over and over and I have no idea why it is doing this. It does this on 3 separate phones and I can't recreate it. I've tried force stopping the app, clearing it from a task manager adding new widgets etc. to get the widget to stop working and it won't. However when I woke up this morning the widget no longer works. Any help would be GREATLY appreciated.

解决方案

I ended up figuring out the problem. I was updating the widget from other places in the app and I did not have the complete code for each one. In other words my app updated the textviews in the widget like this

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

    views.setTextViewText(
            R.id.widgetTextView,
            "Some text");

    appWidgetManager.updateAppWidget(appWidgetId, views);

But it needed the entire code to keep the button registered like this:

    Intent intent = new Intent(context, ServiceWidgetAction.class);
    intent.setAction(Long.toString(System.currentTimeMillis()));
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

    PendingIntent pendingIntent = PendingIntent
            .getService(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

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

    views.setOnClickPendingIntent(R.id.widgetButton, pendingIntent);

    views.setTextViewText(
            R.id.widgetTextView,
            "Some text");

    appWidgetManager.updateAppWidget(appWidgetId, views);

So bottom line is whenever you update a widget from within your app, make sure it looks exactly like the code in the widget itself. Don't leave anything out.
