Question

我正试图用Backendless第一次运行我的应用程序。我收到了这个错误：

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.backendless.BackendlessCollection" on path: DexPathList[[zip file "/data/app/com.asd.asd.android-1/base.apk"],nativeLibraryDirectories=[/data/app/com.asd.asd.android-1/lib/arm, /vendor/lib, /system/lib]]

由于我甚至不使用BackendlessCollection类，因此堆栈跟踪无法解释可能出错的问题。错误点在：

Backendless.initApp(this,app_ID,android_ID, version_id);

这是Backendless中的一个已知问题，它已在新版SDK中得到修复。这是关于maven central http://mvnrepository.com/artifact/com.backendless/backendless/3.0.8.1
