Steps:

1. Change minSdkVersion to 19 (for KitKat) in all build.gradle files

2. If Studio show some error messages like below one, you can add dexOptions in the app/build.gradle to fix the error.

Error message:

java.lang.OutOfMemoryError: GC overhead limit exceeded​

Error:org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_67\bin\java.exe'' finished with non-zero exit value 3

Solution:

app/build.gradle

android {

   ............

    dexOptions {

        javaMaxHeapSize "4g"

    }

}
