Question

我最近将我的Xamarin Android应用从Xamarin.Android.Support.* 24.2.1更新为Xamarin.Android.Support.* 25.0.1-rc1，在应用启动时，我遇到了以下崩溃（100％次）：

Java.Interop.JniEnvironmentFile res / drawable / abc_vector_test.xml 来自可绘制的资源ID＃0x7f020052原始 System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw（）＆LT; 8b63ef277e2c4e9d9f893013919f3ba1＆GT;：0 Java.Interop.JniEnvironment.InstanceMethods.CallNonvirtualBooleanMethod（JniObjectReference 实例，JniObjectReference类型，JniMethodInfo方法， JniArgumentValue * args）＆lt; 554948e16e364ff9b0647fa258ff9398＆gt;：0 Android.Runtime.JNIEnv.CallNonvirtualBooleanMethod（IntPtr jobject， IntPtr jclass，IntPtr jmethod，JValue * PARMS）LT; 06feabe0ae89449c881f9479237416ed＆GT;：0 Android.Support.V7.App.AppCompatActivity.SupportRequestWindowFeature（INT FEATUREID）LT; 2653bed97fbe416083d2f0e662e3d9c0＆GT;：0

我没有使用res/drawable/abc_vector_test.xml资源，所以不确定这次崩溃是什么。

我在这里添加我的包配置：

从25.0.1-rc1回滚到24.2.1解决了这个问题，但只要25在RC中，我就会担心未来的兼容性。

确保在应用初始化中设置一次：

AppCompatDelegate.CompatVectorFromResourcesEnabled = true;

Xamarin支持库从24.2.1更新到25.0.1-rc1后，Android应用启动时崩溃
