java.lang.NoClassDefFoundError: Failed resolution of: Lio/fabric/sdk/android/services/common/FirebaseInfo;

Question

I'm having issues when trying to run my app in Lollipop, the log is the following:

My gradle:

buildscript {

    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.21.6'

}

    buildToolsVersion '25.0.0'

    defaultConfig {
        applicationId "com.rocketjourney"
        minSdkVersion 21

    dexOptions {

        jumboMode = true
    }

    dependencies {
      compile 'com.android.support:multidex:1.0.1'
  compile('com.crashlytics.sdk.android:crashlytics:2.7.1@aar') {
        transitive = true
        exclude group: 'com.android.support', module: 'support-annotations'
    }
    ...

I have this on my launch activity:

@Override
    public void onCreate(Bundle savedInstanceState) {
        MultiDex.install(this);
        super.onCreate(savedInstanceState);

when I try to solve this problem, a problem of multiDex appears, so I have no clue what is the main reason why this is appearing since I have tried many solutions but I didn't have luck. Any help is appreciated.

Answer 1

type rm -rf .gradle in your Android Studio Terminal and then try again. That solves it for me!
