java.lang.NoClassDefFoundError: Failed resolution of

I installed jrebel for android on android studio, and this error occurred at startup

Here's my configuration:

my jdk version :jdk1.8.0_91

compileSdkVersion 24

buildToolsVersion "25.0.0"

classpath 'com.android.tools.build:gradle:2.3.3

Does anyone know why?

java.lang.NoClassDefFoundError is very different with java.lang.ClassNotFoundException. you can try these methods:

  1. make your Application extends MultiDexApplication(compile 'com.android.support:multidex:1.0.1')
  2. disable instant run
  3. try without jrebel

It may be caused by a crash of multi-dex files.

more: On the same devices,e.g. In some ROMs, you can uninstall the app by the ADB command:

adb uninstall packageName

Please have a look at the following Thread. This will solve your problem

You are running into the Multidex problem with device version <21
