Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
Job failed, see logs for details

Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease' means that
you're using proguard in release.
Try to set minifyEnabled option in your build.gradle file to false.
Like this:
buildTypes {
release {
minifyEnabled false
...
}
}

if your app still working when you make
minifyEnabled false
then you have to dontwarn manually every warning that you have with -dontwarn
Exempel: -dontwarn java.lang.invoke.**

:starChef:transformClassesAndResourcesWithProguardForRelease FAILED

Normally Amazon suggests including the following in your ProGuard configuration file:
-dontwarn com.amazon.**
-keep class com.amazon.** {*;}
-keepattributes *Annotation*
and also skipping ProGuard's optimization:
-dontoptimize
However, in my personal experience, including suggestions from numerous other SO posts, none of that worked. In the end I had to turn off obfuscation (minifyEnabled false) to build for Amazon, which produced the release build:
android {
...
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
}
You may also want to experiment by adding this to your ProGuard settings:
-dontshrink
-keep class org.apache.** {*;}
-keepclasseswithmembernames class * {
native <methods>;
}

May be you are mismatching between
sdk version
Build Tools
Gradle Plugins
in terms of compatibility.
To resolve it, verify that you are using the latest versions of them. The gradle plugins are placed in the build.gradle of the project, and the other versions are on the build.gradle of the module.
For example, for SDK 23, you can use the Build Tools 23.0.1 and gradle plugins version 1.3.1.
clean it after change settings.

If you have several modules in your project, try to add
-dontwarn com.amazon.**
-keep class com.amazon.** {*;}
-keepattributes *Annotation*
-dontoptimize
to each proguard-rules.pro file in these modules.
For example, if you have two modules: base and installed, add the lines to both files:
base/proguard-rules.pro
installed/proguard-rules.pro

Android Volley Signed Apk Issue

I am working with an application where I am using volley plus with android studio. I am using volley plus gradle version 'dev.dworks.libs:volleyplus:+' gradle. When I make signed apk of my app my build process terminated with some warning and errors with runProguard true. There is any solution to solve this.

Use this code in ProGuard:
-dontwarn org.apache.http.**
-dontwarn android.net.http.AndroidHttpClient
-dontwarn com.google.android.gms.**
-dontwarn com.android.volley.toolbox.**

Since android API 23 Apache HTTP Client is removed from Android:
https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-apache-http-client
But Volley still uses it, that's why there is warn about can't find referenced class
We can ignore these warns, because Volley is still compiled using API 22:
https://github.com/mcxiaoke/android-volley/blob/master/gradle.properties
Still should think about other better libray like OkHttp, which uses HttpURLConnection, if Volley doesn't update in the future.

If you are pretty confident about your dependencies
You can also use:
-ignorewarnings
This proguard option will take care of all potential warnings simply by ignoring them.
