Proguard：

# Add project specific ProGuard rules here.
# You can control the set of applied configuration files using the
# proguardFiles setting in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile

-dontwarn okhttp3.**
-dontwarn okio.**
-dontwarn org.codehaus.mojo.animal_sniffer.**
-dontwarn javax.annotation.**
-dontwarn org.conscrypt.**

Answer 1

将-keep class androidx.core.app.CoreComponentFactory { *; }添加到您的proguard配置中，以防止此类被阻止

Answer 2

尝试禁用即时运行。这可以通过Android Studio中的设置（文件->设置->生成，执行，部署->即时运行）完成：

关于appComponentFactory
