问题描述
迁移到 AndroidX 后，我在启动时遇到以下异常:
After migration to AndroidX i have the following exception at startup:
LoadedApk: Unable to instantiate appComponentFactory

我在 Windows 10 中使用 Android Studio 3.4.1.
I´m using Android Studio 3.4.1 in Windows 10.
我尝试了所有我能找到的解决方案，但问题仍然存在:
I tried all solutions that I could find, but the problem persists:
AndroidX 在发布模式下关于 appComponentFactory 构建失败
我添加了 -keep class androidx.core.app.CoreComponentFactory { *;} 到 proguard-rules.pro，我将 android.useAndroidX=true 和 android.enableJetifier=true 添加到 gradle.properties...清理、重建、使 chaches 无效并重新启动...
I added -keep class androidx.core.app.CoreComponentFactory { *; } to proguard-rules.pro, i added android.useAndroidX=true and android.enableJetifier=true to gradle.properties... clean, re-built, invalidate chaches and restart...
也禁用即时运行...
另一个奇怪的事实是，我可以毫无问题地从其他类导入类(导入 androidx.core.app.CoreComponentFactory;).
Another curious fact, is that I can import the class without problems (import androidx.core.app.CoreComponentFactory;) from other classes.

目前这不会导致 ANR，应用程序启动并正常运行，但我担心它会在未来引起问题，我想知道为什么会这样.
For now this doesn't cause an ANR, the app starts and works normally, but i'm afraid it will cause problems in the future, and i would like to know why that's happening.
有人遇到过这个问题吗?是怎么解决的?
Has anyone had this problem? How was it solved?
推荐答案
看起来 CoreComponentFactory 类正在加密.尝试将上述类添加到 proguard-rules.
Looks CoreComponentFactory class is getting encrypted. Try adding the above class to proguard-rules.
-keep class androidx.core.app.CoreComponentFactory { *; }
所以 CoreComponentFactory 不会再被加密了.
So the CoreComponentFactory won't be the encrypted anymore.
