问题描述 / Issue Description:
Error
RuntimeException: MToolBackend could not be started.

Service: app.mtool.mtoolmobile.mtool.services.MToolBackend
Process: app.mtool.mtoolmobile:MTOOL_MToolBackend

Android refused to launch the backend service.

Android error:
Unable to start service Intent { act=app.mtool.mtoolmobile.MTOOL_BACKEND_SERVICE cmp=app.mtool.mtoolmobile/.mtool.services.MToolBackend }: Unable to launch app app.mtool.mtoolmobile/10498 for service Intent { act=app.mtool.mtoolmobile.MTOOL_BACKEND_SERVICE cmp=app.mtool.mtoolmobile/.mtool.services.MToolBackend }: process is bad

The backend process was marked as bad by Android, usually because it crashed during an earlier startup attempt. The original crash happened before this retry.
