In MainActivity

<MainActivitiy>

tv.setText(getString(R.string.GPS_info, provider, latitude, longitude, altitude, accuracy));

The %Lf format arguments are the problem. I'm not aware of any L character to be used for numeric format arguments (only for date arguments).

%Lf

L

Change your string to

<string name="GPS_info">Provider : %s
longitude : %f
latitude : %f

altitude : %f
accuracy : %f</string>


Note also that in your string you have longitude before latitude, but in your java code you're passing latitude before longitude. This will mean lat/lng are swapped in the string, which shouldn't break anything, but won't be what you want.

you should implement it like this:

tv.setText(getString(R.string.GPS_info)+ getString(R.string.provider));
