Error encountered while retrieving the Android version

Question

I want to print the android version of the phone by using android.os.build.version.release. But I cant able to print that on the main activity.I have created a text-field about the version.

Operating System : ( now I want to print the details here).

I have just started android programming so I am a noob so please help me.

Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers. — 2Dee, Jan 29 '15 at 13:34

you should share some code fragments...

Usually you get the data you want with this:

Build.VERSION.RELEASE

This will print e.g. "4.4.3" wherever you set the text (e.g. editText.setText(Build.VERSION.RELEASE).

Consider tv as your TextView. Build.VERSION.RELEASE will return a user-visible version string e.g. "2.3.3".

String osVersion = "Operating System : "+Build.VERSION.RELEASE;
tv.setText(osVersion);
