Android- Error:Execution failed for task ‘:app:transformClassesWithDexForRelease’
i fixed it just this code. local.properties org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m and you should do this changing on gradle defaultConfig { applicationId “yourProjectPackage” minSdkVersion 15 versionCode 1 versionName “1.0” targetSdkVersion 23 multiDexEnabled true //important }
