我最近将Xamarin Android应用程序从Xamarin.Android.Support.* 24.2.1更新为Xamarin.Android.Support.* 25.0.1-rc1，并且在应用程序启动时，我会得到以下崩溃（100％次）：
java.interop.jnienvironmentfile res/drawable/abc_vector_test.xml 来自 可绘制的资源ID＃0x7F020052 RAW system.runtime.exceptionservices.exceptiondispatchinfo.throw（） java.interop.jnienvironment.instancemethods.callnonvirtualbooleanmethod（jniobjectReference 实例，jniobjectReference类型，jnimethodinfo方法， jniargumentValue* args）＆lt; 554948e16e364ff9b0647fa258ff9398>：0 android.runtime.jnienv.callnonvirtualbooleanmethod（intptr jobject， INTPTR JCLASS，INTPTR JMETHOD，JVALUE* parms）＆lt; 06feabe0ae89449c881f9479237416ed>：0 android.support.v7.App.AppCompatactivity.SupportrequestWindowFeature（int featureID）＆lt; 2653bed97fbe416083d2f0e662e3d9c0>：0
我不使用res/drawable/abc_vector_test.xml资源，所以不确定这是什么崩溃。
我在这里添加我的软件包配置：

从25.0.1-rc1滚动到24.2.1可以解决这个问题，但我担心将来的兼容性只要25在RC中。
请确保在应用程序初始化中设置一次：
AppCompatDelegate.CompatVectorFromResourcesEnabled = true;
