Answer 1

The steps below helped me get out of this situation:

• File -> Invalidate Caches / Restart -> Invalidate and Restart
• Build -> Clean Project

Hope that helps!

Answer 2

I ran into this issue when opening a React Native project incorrectly.

To fix this, I:

• File > Close Project
• Removed Project from the Welcome screen (cosmetic and not to get me into this mess again)
• Chose > Import project (Gradle, Eclipse, ADT, etc.)
• Chose my react-native-app-folder/android

After doing this, all errors were gone.

Answer 3

I had this issue while editing the project structure of a Flutter project. My project was working fine before that.
So probably it was due to some misconfiguration.
I solved doing this:

• close AndroidStudio
• go to your/project/path and delete the .idea folder from your filesystem
• open again your project with android studio

I tried one File > Invalidate Cache / Restart .. before doing that, but it was probably useless.

Answer 4

The problem was resolved for me , after I made a fresh installation of studio.

For this

Step 1. Uninstall Android Studio. While uninstalling please make sure that you selected the additional option Android User Settings also.

Step 2. Goto user's home folder and delete folders .gradle, .AndroidStudiox.x(if it's still there). No need to delete or rename or relocate Workspace fodler.

Step 3. Now install android studio again.

Step 4. Let it download and build gradle.

Step 4. DONE.. :D
