I am doing a project in Android Studio and today I saw that suddenly all my code has errors and even the line:
import com.google.android.gms.appindexing.Action;
has error: cannot resolve symbol android
any suggestions why this might have happened?

- At top of Android Studio there is the "Build" option, click there and then select "Clean Project".Gueorgui Obregon– Gueorgui Obregon2016-01-28 22:18:40 +00:00Commented Jan 28, 2016 at 22:18

Please ensure you have mention in your project grades it has been tested and working fine
dependencies { ... compile 'com.google.android.gms:play-services-appindexing:8.4.0' ... } clean your project and rebuild again and wait till android studio make indexing and loaded all resource some time due to system it will slow. please comment if you found something else. happy coding :)

1st update your SDKs ( Android tools SDK & Google play service)
in your build.gradle "modules" include this code in your dependencies
compile 'com.google.android.gms:play-services-places:<version> where is the latest version available...my version at the time of this answer is 11.0.4

Please try as follows

- Back up your project
- Delete all the .iml files and the .idea folder
- Relaunch Android Studio and reimport your project
or
- Exit Android Studio

What I did: in Android Studio Settings --> Build, Execution, Deployment Build Tools --> Gradle I had set the value of the field Gradle User Home.
I did that, because it was displaying a wrong path (perhaps from an earlier installation?) But what I put in was really a guess.
But it caused several problems, including a thousand warnings "cannot resolve symbol 'android'"
I fixed it by emptying the field (then Clean Project, then in Terminal ./gradlew clean, then File --> Invalidate Caches... because ... who knows? does anybody really know?)
