I'm sorry, this question seems to leave a lot of information off the table.
What problem do you have?
Once we've identified the problems that mere humans doing actual testing can't solve, the "gap", we can start to look for tools. (Or, in some cases, the opportunities that tools could do to speed things up.)
Sorry, I really don't understand which latest android app testing services for bug fixing that you've in your mind, but I suggest you to use innovative testing methodologies and best practices to ensure quality of mobile applications... Just try the tools like Robotium, Appium for mobile applications testing to get your app tested in a much faster, deeper and wider manner...
