Cannot resolve symbol 'R' error

When changing the .png file for the image I wouldn't get the new image to show up, I just kept seeing the default app image. So I saw a Clean and Rebuild was recommended so I gave it a try. This resulted in an error with "R" any help would be appreciated.

The error message from Gradle Build:

Error:(13, 23) No resource found that matches the given name (at 'icon' with value '@drawable/ic_launcher'). Error:(13, 23) Execution failed for task ':app:processDebugResources'.

com.android.ide.common.internal.LoggedErrorException: Failed to run command: C:\Users\Tommy\Documents\android-studio\sdk\build-tools\android-4.4W\aapt.exe package -f --no-crunch -I C:\Users\Tommy\Documents\android-studio\sdk\platforms\android-19\android.jar -M C:\Users\Tommy\AndroidStudioProjects\FunFacts\app\build\intermediates\manifests\debug\AndroidManifest.xml -S C:\Users\Tommy\AndroidStudioProjects\FunFacts\app\build\intermediates\res\debug -A C:\Users\Tommy\AndroidStudioProjects\FunFacts\app\build\intermediates\assets\debug -m -J C:\Users\Tommy\AndroidStudioProjects\FunFacts\app\build\generated\source\r\debug -F C:\Users\Tommy\AndroidStudioProjects\FunFacts\app\build\intermediates\libs\app-debug.ap_ --debug-mode --custom-package com.example.tommy.funfacts -0 apk Error Code: 1 Output: C:\Users\Tommy\AndroidStudioProjects\FunFacts\app\build\intermediates\manifests\debug\AndroidManifest.xml:11: error: Error: No resource found that matches the given name (at 'icon' with value '@drawable/ic_launcher').

Here is my code from FunFactsActivity.java

Hello,

Current versions of Android studio store their icons(and only icons) in a folder called mipmap now. So to reference the launcher icon it would need to be converted to @mipmap/ic_launcher in your AndroidManifest.xml file. Also double check to make sure ic_launcher.png exists.
