After installing Xender on my Android Mercury tablet, it doesn't work and it informs me that 'Unfortunately Xender has stopped'.
There could be many sources of this error: system compatibility, file corruption, application blocking, bugs, etc. The first thing to do is to re-install the application through Google Play.
