Proguard在APK导出时返回了错误代码1

Question

I am developing Android application using Parse library and many different library projects. For exporting apk file, I am using Pro Guard. While doing the export of the apk file I am receiving the following error:

[2015-05-03 20:59:49 - SampleProject] Proguard returned with error code 1. See console

Answer 1

In your proguard-project.txt add this -dontwarn and - keep class lines:

 -keep class com.parse.*{ *; }
 -dontwarn com.parse.**
 -dontwarn com.google.common.**
 -dontwarn org.hamcrest.**
