app加固后不能再模拟器中报错:Didn't find class "androidx.core.app.CoreComponentFactory"

这个错误通常是由于应用程序使用了AndroidX库,而模拟器中的Android版本过低导致的。请尝试以下解决方案:
1. 更新模拟器的Android版本至最新。
2. 在应用程序的build.gradle文件中添加以下代码:
```
android {
configurations.all {
resolutionStrategy {
force 'androidx.core:core:1.3.1'
}
}
}
```
这将强制Gradle使用最新版本的`androidx.core`库,可能会解决该问题。
3. 如果您使用了某些加固工具或者混淆,请确保您已经正确配置了混淆规则。在应用程序的proguard-rules.pro文件中添加以下代码:
```
-keep class androidx.core.app.CoreComponentFactory { *; }
```
这将保留`androidx.core.app.CoreComponentFactory`类,可能会解决该问题。

java.lang.ClassCastException: androidx.core.app.CoreComponentFactory cannot be cast to android.app.AppComponentFactory
这个错误通常是由于在应用程序中使用了不兼容的Android库版本造成的。你可以尝试以下解决方法:
1. 确保你的应用程序中所有引用的库都使用相同的Android库版本。
2. 更新你的Android库版本到最新版本。
3. 确保你的应用程序中没有使用重复的库。
4. 如果你的应用程序中使用了自定义的AppCompatActivity或Application类,确保它们继承自正确的类。
请注意,这只是一些可能的解决方法之一,具体的解决方法取决于你的应用程序和你使用的库。
Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v4.content.LocalBroadcastManager"
This error message indicates that the application is trying to use the LocalBroadcastManager class from the Android Support Library, but the class is not present in the application's classpath.
To solve this issue, you can try the following steps:
1. Make sure that you have added the Android Support Library to your project's dependencies. You can do this by adding the following line to your app's build.gradle file:
implementation 'com.android.support:support-v4:28.0.0'
2. If you have already added the Android Support Library, try cleaning and rebuilding your project. Sometimes, the build process can fail to update the classpath, which can cause this error.
3. If the above steps do not work, try updating the Android Support Library to the latest version. You can do this by changing the version number in the implementation statement in your build.gradle file:
implementation 'com.android.support:support-v4:28.0.0' -> implementation 'com.android.support:support-v4:28.0.0-alpha1'
4. If none of the above steps work, try adding the following line to your app's build.gradle file:
android {
...
useLibrary 'org.apache.http.legacy'
...
}
This will enable the use of the deprecated Apache HTTP client library, which may be required by some older versions of the Android Support Library.
