标签： android apk build.gradle build-error

【解决方案1】：

如果您在应用程序模块中将minifyEnabled 设置为true，您可能希望按照here 的描述将以下行添加到您的proguard-rules.pro 文件中。

-dontwarn com.squareup.okhttp.**

【讨论】：

我已经这样做了。在 proguard-project.txt -keepattributes SourceFile,LineNumberTable -keep class com.parse.*{ ; } -dontwarn com.parse.* -dontwarn com.squareup.okhttp.** -dontwarn com.squareup.picasso.s** -keepclasseswithmembernames class * { native ; }
你在使用 Android Studio 吗？
然后在android 中添加lintOptions { abortOnError false } build.gradle
apk 生成成功，但是生成的 apk 没有安装在任何安卓设备中。
这将是一个全新的 Stackoverflow 问题！

【解决方案2】：

请在 progaurd 规则文件中添加如下 -dontwarn，

-dontwarn com.squareup.picasso.**
