Android Studio cannot resolve getDefaultProguardFile

Question

When I run my program i get no problems. When I try to generate signed apk, I am told that getDefaultProguardFile cannot be resolved. How can I fix this. Here is the code.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.dose.apps.brainnoodles"
        minSdkVersion 8
        targetSdkVersion 21
        versionCode 13
        versionName "2.13"
    }
    buildTypes {
        release {
            //apply plugin: 'idea'
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile files('libs/InMobi-4.5.3.jar')
}

Here's the stacktrace that was asked

         If your code works fine without the missing classes, you can suppress

It might seems you do not need to set hard coded path , Studio will get it automatically — Kirtikumar A., Mar 20 '15 at 05:03
can you post the stacktrace by running the gradle command in the terminal — Raghunandan, Mar 20 '15 at 05:11

@ThatThatson seems that you have not referenced the libraries properly. I can see a lot of can't find referenced method messges — Raghunandan, Mar 20 '15 at 05:37
@Raghunandan Well what should I do? I only get this error when I set minifyEnabled to true. — That Thatson, Mar 20 '15 at 05:45

I had the same problem. Note that in the log they are pointing you to go to http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember and there it says:

If you're developing for Android and ProGuard complains that it can't find a method that is only available in a recent version of the Android run-time, you should change the build target in your project.properties file or build.gradle file to that recent version. You can still specify a different minSdkVersion and a different targetSdkVersion in your AndroidManifest.xml file.

I changed the compileSdkVersion & targetSdkVersion from 21 to 22 and it worked.

@That Thatson :

Just update your buildTypes instead your . Try this way.

buildTypes {
        release {
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

You might have to replace the buildtypes codepart with this

signingConfigs {
    release {
        storeFile file("release.keystore")
        storePassword "******"
        keyAlias "******"
        keyPassword "******"
    }
}

buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}
