Question

我在某些设备上测试我的Android应用程序，并且我注意到某个移动设备中存在奇怪的行为。当我第一次打开生成此堆栈跟踪时，打开一个Activity（显示一个位图）：

但是，如果我尝试再次打开活动，则不会发生这种情况。此外，在我测试过的任何其他设备中都没有发生这种情况。我想移动设备没有足够的ram atm，这个例外有助于它清理内存，但这只是我的猜测。为了克服这个问题，我该怎么做？

Answer 1

你可以尝试一些想法：

a）尝试使用小图片查看是否是由于位图的大小。

b）您拥有州的第一个原因：

Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class <unknown>

我还会检查您在此处使用的课程是否受该特定设备的支持。

例如，我记得我开发的应用程序崩溃了没有谷歌认证的设备因为我认为所有设备都有谷歌地图而事实并非如此。我必须在实例化对象之前添加运行时检查。
