Getting error when build apk using proguard and build-variant is release in android

Question

Hello everyone, I am trying to build my apk with build-variant release but facing some error.I have also try to use -keep,-keepclassmembers,-keepclasseswithmembers and -dontwarn in proguard-rules.pro,but not able to get any solution.I am not having default proguard-rules.pro so I copied it from another project.I want to know how can i build my apk with release.

       **This is my build.gradle file**
        apply plugin: 'com.android.application'  android {

                    keyPassword 'password'
                    storeFile 'keycorner.jks'
                    storePassword 'password'
                }
            }
            compileSdkVersion 23
            buildToolsVersion "23.0.2"
            defaultConfig {
                applicationId "com.example.demo"
                minSdkVersion 11
                targetSdkVersion 23
                multiDexEnabled true

            }
            dexOptions {
                incremental true
                javaMaxHeapSize "4g"
            }
            lintOptions {
                disable "ResourceType"
            }
            buildTypes {
                release {
                    minifyEnabled true
                    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
                }

To get past the current error you need to add the following to your ProGuard configuration rules:

-dontwarn net.authorize.sim.Transaction

After that you might still need to add additional -keep rules but at least the build should not fail anymore.
