关于dialog报错问题：Expected receiver of type android.app.AlertDialog, but got java.lang.ref.WeakReference
我的compileSdkVersion 30
MessageDialog里面的showEvent方法反射获取AlertController报错，这个对象已经被标为@UnsupportedAppUsage， 不允许反射拿了，博主更新处理下这个问题
报错信息： java.lang.IllegalArgumentException: Expected receiver of type android.app.AlertDialog, but got java.lang.ref.WeakReference W/System.err: at java.lang.reflect.Field.get(Native Method) W/System.err: at com.kongzue.dialog.v3.MessageDialog.showEvent(MessageDialog.java:630)
问个问题，是compileSdkVersion == 30 才会报错 还是，android 11 的手机都会报错？
----------------更新--------------------
奇怪，我用 compileSdkVersion = 30 minSdkVersion = 21 targetSdkVersion = 30
这个配置是去编译，然后跑在android 11的模拟器上，并没有崩溃
想问下用的是AndroidX版本么？目前我这边的项目也在用但没遇到这个问题
我用的androidX版本但没有崩溃，等我的小米9更新android11后我再测试，但是考虑到android越来越严厉的策略，感觉确实应该减少反射的使用
MessageDialog不存在反射

并不是崩溃，而是引用历史缓存的dailog由于拿不到导致dialog显示不出来，你可以做个简单的测试，在你测试的demo开启messagedialog，然后点击dialog关闭后跳转到其他app，然后在onresume将该dialog带出来，有时候就会带不出来，带不出来的时候就会有这个错误提示

我引用的版本不对嘛？我这边看代码是：630行，而且AlertDialog和androidx无关，这个属于android自身的 Field mAlert = AlertDialog.class.getDeclaredField("mAlert"); mAlert.setAccessible(true); Object mAlertController = mAlert.get(dialog);

刚刚查了下，这段代码是用于设置AlertDialog的按钮文字样式的，因为Google并没有公开的设置方法不得不这么做。因历史原因，DialogV3框架依然是基于DialogFragment进行的实现，现在我更推荐更新到DialogX这个库（ https://github.com/kongzue/DialogX ）它的Material主题Dialog是纯粹自己做的实现，不存在这些问题。
