Can someone please help me? I followed the instructions at:    https://developer.dji.com//mobile-sdk/documentation/application-development-workflow/workflow-integrate.html#android-studio-project-integration    , only modifying the build.gradle (:app) and entering my API-key in the manifest. But when running the app it crashes with the following message:
