AppWidgetHost崩溃android.os.TransactionTooLargeException [英] AppWidgetHost crash android.os.TransactionTooLargeException

问题描述

我工作的一个定制的Andr​​oid启动。之后，我添加一些小部件（三星画廊，收藏直拨），我每次重新启动应用时，我得到一个崩溃。这是code：

I'm working on a custom android launcher. After I add some widgets (Samsung gallery, Favourite direct dial), every time I restart the app I obtain a crash. This is the code:

public static final int APPWIDGET_HOST_ID = 128;

    public final class Launcher extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 
        mAppWidgetManager = AppWidgetManager.getInstance(this);
        mAppWidgetHost = new AppWidgetHost(this, APPWIDGET_HOST_ID);
        mAppWidgetHost.startListening(); //Here it crash
        ...
    }
}

这是错误日志：

这发生在Android 4.4的（但即使在旧Android版本）
这是什么意思？我怎样才能prevent呢？

This happens on android 4.4 (but even on older android version) What does it mean? How can I prevent it?

推荐答案

请参见 TransactionTooLargeException 的文档。如果你看一下源AppWidgetHost你会发现你的踪迹提到这个code：

See TransactionTooLargeException in the docs. If you look at the source for AppWidgetHost you will find this code mentioned in your trace:

ArrayList<RemoteViews> updatedViews = new ArrayList<RemoteViews>();
// ....
updatedIds = sService.startListening(mCallbacks, mPackageName, mHostId, updatedViews);

在这种情况下，updatedViews是RemoteViews的阵列。这些可以说是相当大的，如果它们含有大量的图片。你有一些小部件与庞大的图像，他们还是怎么的？

In this case the updatedViews is an array of RemoteViews. Those can be quite large if they contain a lot of images. Do you have some widgets with huge images in them or something?
