[英]AppWidgetHost crash android.os.TransactionTooLargeException
I'm working on a custom android launcher. 我正在开发一个自定义的Android启动器。 After I add some widgets (Samsung gallery, Favourite direct dial), every time I restart the app I obtain a crash. 在我添加一些小部件(三星画廊,收藏直接拨号)后,每次重新启动应用程序时都会崩溃。 This is the code: 这是代码:
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
...
}
}
This is the error log: 这是错误日志:

This happens on android 4.4 (but even on older android version) What does it mean? 这发生在Android 4.4(但即使在较旧的Android版本)这是什么意思? How can I prevent it? 我该怎样预防呢?
Thank you, Vincenzo 谢谢你,文森佐
See TransactionTooLargeException in the docs. 请参阅文档中的TransactionTooLargeException 。 If you look at the source for AppWidgetHost you will find this code mentioned in your trace: 如果您查看AppWidgetHost的源代码,您将在跟踪中找到此代码:
ArrayList<RemoteViews> updatedViews = new ArrayList<RemoteViews>();
// ....
updatedIds = sService.startListening(mCallbacks, mPackageName, mHostId, updatedViews);
In this case the updatedViews is an array of RemoteViews. 在这种情况下,updatedViews是一个RemoteViews数组。 Those can be quite large if they contain a lot of images. 如果它们包含大量图像,那些可能会非常大。 Do you have some widgets with huge images in them or something? 你有一些小部件,里面有大量的图像吗?
