Hi I am struggling to create release version for my project. I have been try lot of things on Progaurd through SO / Google help but I am still not able to create the release version.

Can somebody help me with this? I always get this issue:

Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> java.io.IOException: Please correct the above warnings first.

Here is the full detailed error: http://justpaste.it/perror sorry I had to put as a link because it is huge.

Here are dependencies:

//compile fileTree(dir: 'libs', include: ['*.jar'])
 testCompile 'junit:junit:4.12'
 compile 'com.android.support:appcompat-v7:23.1.1'

    This kind of issue has been known to happen when the SDK version, gradle version and build tools version are incompatible: http://stackoverflow.com/questions/33877134/errorexecution-failed-for-task-androidtransformclassesandresourceswithprogua I've faced the same problem, and haven't been able to solve it. I've temporarily fixed it by setting `minifyEnabled` to `false`. – Vedavyas Bhat Dec 22 '15 at 08:54
  • @VedavyasBhat: if we do that it won't Obfuscate my code right? – Sanjana Nair Dec 24 '15 at 15:31

In your ProGuard file add:

-ignorewarnings

like :

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in D:\Softwares\Developing\Android\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# 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 *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile


-ignorewarnings

You wouldn't have to specify any package like com.viewpagerindicator.** , this will suppress all warnings and the Gradle Console will just say like :

......
Warning: there were 4 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning: there were 2 unresolved references to library class members.
         You probably need to update the library versions.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember)

Note: you're ignoring all warnings! 
Ignoring unused library classes...
  Original number of library classes: 4237
  Final number of library classes:    1317
Printing kept classes, fields, and methods...
Shrinking...

In your ProGuard file add:

-dontwarn com.viewpagerindicator.**

If you open up the link you provided and search for 'Warning' about two thirds down you can see the message:

Warning:com.viewpagerindicator.LinePageIndicator: can't find referenced method 'float ceil(float)' in library class android.util.FloatMath

If there are any warnings ProGuard will stop and ask you to fix them first or if your code works you can choose to ignore them with dontwarn.

Update 05/01/2017

If the warning says in program class it is likely that your compiled class files are inconsistent, try removing them all and and rebuilding your project.

If the warning says in library class your compiled class files are inconsistent with the libraries. Try recompiling the class files or upgrading the libraries to consistent versions.

What has helped me was to update all dependencies to last version.

In my case, the proguard file was totally ignored because the project consisted of several modules. According to this answer, the solution was to set the following in the gradle of the module causing the problem:

defaultConfig {
    consumerProguardFiles 'proguard-rules.txt'
}

This seems to include the proguard of the module in the application's proguard. Now my dontwarn statements are taken in consideration.
