NoClassDefFoundError: com.exacttarget.etpushsdk.ETLocationManager$RegionMonitor

Question

I'm receiving a weird problem and I don't know if is a Android related or SDK related. The thing is, I'm following the instructions to add ExactTarget Journey Builder SDK (https://github.com/ExactTarget/JB4A-SDK-Android/) , instructions from here: https://code.exacttarget.com/apis-sdks/journey-builder-for-apps/sdk-implementation/register-your-devices.html

BUT, when I enabled the LocationService, I'm receiving this weird error:

java.lang.RuntimeException: An error occured while executing doInBackground()

What could be? I'm using Android studio and all the dependencies like the instructions.

Answer 1

Roll back play-services version, next change solved issue for me.

build.gradle

    ...
    dependencies {
    ...
    //  use old instead of new because ET location service does not work on new one
    //  compile 'com.google.android.gms:play-services:7.5.0'
        compile 'com.google.android.gms:play-services:6.1.71'
    }
