Java 使用Proguard导出APK在实际设备安装中失败

如果我在android studio中导出我的应用程序，同时runProguard=true并将APK安装到真实设备上，我的应用程序会停止并说：不幸的是[yourapp]已经停止

有什么问题吗？ 我将proguard-rules.txt文件保留为默认状态：

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /Applications/Android Studio.app/sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# 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 *;
#}

没有Proguard，我的应用程序安装和运行都非常完美。

你可以做到这一点

-keep public class * extends android.view.View {
   public <init>(android.content.Context);
   public <init>(android.content.Context, android.util.AttributeSet);
   public <init>(android.content.Context, android.util.AttributeSet, int);
   public void set*(...);
}

-keepclasseswithmembers class * {
   public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
   public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * implements android.os.Parcelable {
   static android.os.Parcelable$Creator CREATOR;
}

-keepclassmembers class **.R$* {
   public static <fields>;
}

也许您正在使用库或java反射代码，proguard有时会从您的代码中收缩。。请查看proguard网站，了解android的推荐设置。。使用-KeepClassmembers
