创建发行版本时,我的应用程序崩溃.该应用程序运行正常,突然之间发生了这种情况.我在BaseActivity.java MultiDex.install(this)中有这行；我尝试了SO的多种选择,但是没有一个起作用.错误也没有提供足够的详细信息,或者我无法找到发生此问题的位置.任何帮助将不胜感激.

这是堆栈跟踪.

使用Proguard规则更新

# 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.

解决方法:

从here

从您的proguard文件中删除以下几行

#1 to
-assumenosideeffects class * implements Interface {
    public <init>();
    public Object interfacemethod(); # May concern methods with same signature in other Objects
}
#end

并更换

-assumenosideeffects class android.util.Log{*;}

用

-assumenosideeffects class android.util.Log {
   public static *** v(...);
   public static *** d(...);
   public static *** i(...);
   public static *** w(...);
   public static *** e(...);
   public static *** wtf(...);

}
