I’v just installed Android Studio 0.8.2 for my first time and I have a lot of “Cannot resolve symbol” errors.
The errors occur on both new projects and projects which were exported from eclipse.
JDK version: jdk1.8.0_11
Android studio errors:
Project’s grade file
In the menu bar
Select tools>-android>-SDK manager
and download the SDK build tools, SDK platform and Google API’s( the Google API stores packages such as “import android.view.Menu” etc.) for the target SDK version of your project(20 as shown in your screenshot).
if you are not sure which items you have to download , you can select all of them.(will take more time to download of course).
Restart the IDE
You can do “File” -> “Invalidate Caches…”, and select “Invalidate and Restart” option to fix this.
- Exit Android Studio
- Back up your project
- Delete all the .iml files and the .idea folder
- Relaunch Android Studio and reimport your project
If your library is an
androidx one and never worked before, the problem is likely the one described in this other question instead.
I run into the same problem, i solved it by performing a clean project. To do this go to;
Select build>-clean project>
