也许问题与apk的签名有关.如果使用debuggable true，则将使用通用调试密钥库对您的应用程序进行签名，并且一切正常. 相反，如果将其删除，则必须提供

Maybe the problem is related to the signing of the apk. If you use debuggable true then your app is signed with a generic debug keystore and everything works correctly. Conversely, if you remove it you have to provide

storeFile file("myreleasekey.keystore")
storePassword "password"
keyAlias "MyReleaseKey"
keyPassword "password"
