I am able to get the path using the cordova.file plugin: file:///data/data/com.ionicframework.myapp123/files
Now I want to list all the files saved by my application in there and delete the unnecessary ones, which eat a lot of space of the memory. I want to do this because of this issue I've been having.
EDIT: I've got the solution after trying out things. Refer this answer of mine here: http://stackoverflow.com/a/28496743/4412363
