NoClassDefFoundError: com.exacttarget.etpushsdk.ETLocationManager$RegionMonitor

Question

我收到一个奇怪的问题，我不知道是 Android 相关还是 SDK 相关。问题是，我按照说明添加 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

但是，当我启用 LocationService 时，我收到了这个奇怪的错误：

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

可能是什么？我正在使用 Android 工作室和所有依赖项，如说明。

回滚播放服务版本，下一个更改为我解决了问题。

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'
    }
