推荐答案

添加的android：hardwareAccelerated =FALSE到＆lt;应用＆GT; 清单是一种解决方法，但没有解决问题。正如菲尔提到可能在这里发挥作用的OpenGL状态和情境preservation。

Adding android:hardwareAccelerated="false" to the <application> manifest is a workaround, however does not solve the problem. OpenGL state and context preservation as mentioned by Phil might play a role here.
