If you're using Android Studio without gradle then Preferences->Compiler->Android Compilers->Force Jumbo Mode

If your using gradle then add to build.gradle

android {
    dexOptions {
       jumboMode true
    }

There's a limitation in Android on the number of Java methods you can have in a single dex file, and you're hitting that limit. Unfortunately, there's no easy solution to it. Your choices are:

  • Simplify your code. If you're using a lot of libraries, see if you can cut back on the number of libraries you're using. Some libraries have a lot of methods in them.
  • Use ProGuard even in your debug builds. ProGuard will strip out unused methods and can save a lot of space. To get started on ProGuard, look at these links:

If those approaches don't work, it's possible to split your application into multiple dex files and use classloader tricks to make it work at runtime, but that's more complicated.
