问题
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?

回答1:
java.lang.NoClassDefFoundError is very different with java.lang.ClassNotFoundException. you can try these methods:
- make your Application extends MultiDexApplication(compile 'com.android.support:multidex:1.0.1')
- disable instant run
- try without jrebel
It may be cause crash by multi-dex files.

Please have a look at the following Thread. This will solve your problem
Android: ClassNotFoundException while class is present
You are running into the Multidex problem with device version <21
