Error:Execution failed for task ':app:transformClassesWithDexForDebug' in android

Question

I am stuck with this error for 2 days.

Error:Execution failed for task
':app:transformClassesWithDexForDebucom.android.build.api.transform.Transfor mException:com.android.ide.common.process.ProcessException:java.util.concurrent.ExecutionException:com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

Here is the gradle file:

apply plugin: 'com.android.application'

   android

If I do not add multidex then it won't generate apk. And if I add multidex it shows error in another class, like it won't be able to import some default classes. It says class not found. And those classes I am getting from a module imported in my project. I don't get what's the issue. Thanks in advance.

Add this line in your gradle file and then clean the project and run application

android {
...
defaultConfig {
    ...
    multiDexEnabled true
    }
}
