Question

This is happening after I launched AVD for app test, and it was starting android OS. few seconds later, my computer( using Mac) was restarted by causing error Android Studio. After the happening, my Android Studio is strange.

• It was working well, but it suddenly happened.
• Android Studio does not still work after I used a Clean Project ,and it can't recognize things such as R. , all those methods.

Thank you :)

I attached the screenshot for your understanding.

Answer 1

Your styles.xml is error. So you have to fix it and clean your project. I think you are trying to add AppCompat to your project. Did you add the following line in your dependencies?

compile 'com.android.support:appcompat-v7:23.1.1'

Answer 2

Make sure you are using the same compile SDK version and the app compat version. Check your gradle file.

For example, if you are compiling with SDK 23

compileSdkVersion 23

You must use the same app compat version 23.xx

compile 'com.android.support:appcompat-v7:23.4.0
