Fixed: R cannot be resolved to a variable

I encountered this problem when I was making a new project on my eclipse workspace. I got a red underline on “R” in this part of my code


So here’s what I did to fix this issue. Go to Project Properties > Java Build Path > Tick Android Version Checkbox

Then if your workspace does not build automatically…

Properties again > Build Project

After that, all went back to normal. :)

  3. This helped a ton with my file path problem when trying to add an audio file [ex: mp1 = MediaPlayer.create(this, R.raw.audiofile); but only after I made sure that the audio file name was in ALL lowercase. The error popped up only while the audio name had a cap in it like: audioFile.mp3. Until the mp3 name was switched to all lowercase the path could not be resolved.

  4. I had this problem for weeks ! I tried every thing that was in the websites ! and now the problems are gone ! i didn’t get what happened ! but so happy … thank u a lot !
