transformClassesAndResourcesWithProguardForRelease FAILED
Try adding this code to your proGuard rules, it worked for me
-ignorewarnings-keep class * { public private *;}The answer was posted here: Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease
add this code to ..your-project/app/proguard-rules.pro
-ignorewarningsyour signed apk will be generated successfully...
Update :
That's better to fix your warning messages using
-dontwarnor-keepkeys on yourproguard-rules.pro... Because if you use (maybe your libraries) java reflection in your code the application will be crashed...
It worked for me I also had to add following in a pro-gaurd.txt file
#### -- Picasso -- -dontwarn com.squareup.picasso.** #### -- OkHttp -- -dontwarn com.squareup.okhttp.internal.** #### -- Apache Commons -- -dontwarn org.apache.commons.logging.** -ignorewarnings -keep class * {public private protected *;}
