Google Maps API Android - NullPointerException - setBoundsInParent

Question

在我们的Android移动应用程序(与Android 4.0及更高版本兼容)中,我们使用Google Maps API V2.

在android.view.accessibility.AccessibilityNodeInfo类的setBoundsInParent方法中,我们从某些类型的设备(Android版本4.3,4.4和5.0)上获得了一些bug报告,其中包含NullPointerException.

当用户尝试移动或缩放地图时,应用程序崩溃.

该问题仅出现在某些用户 - 设备上.我们的大多数客户都没有这个问题.

问题似乎来自使用Google Maps API的setPadding方法定位Google徽标,以便在地图上始终清晰可见:

@Override
protected void onCreate(Bundle savedInstanceState)
{
                ... 
        // Initialize map
        ...     
        // Sets the padding for the map
                if(mMap!=null)
                {
                     mMap.setPadding(0, DPI.toPixels(100), 0, DPI.toPixels(100));
                }
                ...
}

删除对setPadding方法的调用似乎可以解决受影响用户的问题,但它不适合我们,因为我们需要使用此方法定位Google徽标.

我们无法在我们的开发设备上重现这个问题,因此我们很难找到这个问题的真正根源.

您将在下面找到该错误的完整堆栈跟踪.

有人有想法吗？

非常感谢您的回答.

最好的祝福.
