I am searching for a tool/software for black box testing of android apps. I researched for some of them-Robotium, Calabash. But these tools require access to the source codes.
Also the tool should be free and opensource for use.
You can also use Calabash-Android. It does not need access to source code and you can use it with a signed .apk file. You would only need to know the id of the UI elements if you want to manipulate them.
