问题
I am writing an application for the Android for an examination. One of the features of the application is the keylogger that captures everything that user types. I didn't understand how I could implement the functionality of keylogger, if is possible to catch everything a user types and unfortunately I found very little code in the network. Can anyone help me? Thanks for the attention

I might be wrong but I believe that your application can catch only those inputs which were made inside the application. I do not think Android gives you the ability to capture all the key events in all the applications, from your application. So, you can get only those key-events which were targeted to your application in particular..
EDIT : I looked around on the internet and it seems that there a few unethical ways of doing this. You can create your own custom keyboard and catch the inputs from there. Another way of achieving this would be to run a service in the background with a KeyListener activity to catch the key-events.
