java.lang.noClassDefFoundError on Android 4.4.4, works on 5.0+

I am getting this error:

but I know that the mentioned class is a dependency. I've looked through the jar file myself. Also, I only get this error below 5.0.

My gradle file includes compile 'com.google.code.gson:gson:2.5'

Use compile 'com.android.support:multidex:1.0.0' then extends MultiDexApplication in your application class.

NoClassDefFoundError in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available during compile time. For example, if we have a method call from a class or accessing any static member of a Class and that class is not available during run-time then JVM will throw NoClassDefFoundError.

You can try with

compile 'com.google.code.gson:gson:2.3'

Then , Modify your app Gradle build file configuration to include the support library and enable multidex output .

    android {
    compileSdkVersion 21 // Set Yours
    buildToolsVersion "21.1.0" // Set Yours

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21 // Set Yours
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

This thing happens a lot. You should be able to fix by doing the following,

multiDexEnabled = false

in your build.gradle file.

If you already have multiDexEnabled = true then change it to false or add this new line.
