I am trying to use GoogleMap V2 .But i am getting error on import these :
import android.support.v7.app.MediaRouteActionProvider;
import android.support.v7.media.MediaRouteSelector;
import android.support.v7.media.MediaRouter;
import android.support.v7.media.MediaRouter.RouteInfo;
And the error is
The import android.support.v7.app.MediaRouteActionProvider cannot be resolved
Here is the screen shot of the library that i have added
What i have to do .I have tried to import android\support\v7 By Build path .But it is not resolving my issue in there any way so that i can resolve these errors.
It looks like you have added gridlayout.jar to the projects lib folder.
Its a library project with resources. You need to reference the library project in your android projet
This library is located in the <sdk>/extras/android/support/v7/gridlayout/ directory after you download the Android Support Libraries.
Follow Adding libraries with resources
http://developer.android.com/tools/support-library/setup.html#libs-with-res
had the same problem and found that the link in my project to the appcomcat_v7 project is broken (right-click project and choose properties, then head to the Android tab)...
i removed and then added the correct project and i was good to go...
These type of Errors generally occurs when we accidentally close these libraries(by close unrelated projects,etc) which are automatically generated In Project Explorer of Eclipse like:
- appcompat_v7
- appcompat_v7_2
- appcompat_v7_3
- appcompat_v7_4
- appcompat_v7_5
- appcompat_v7_6
- appcompat_v7_7
- appcompat_v7_8
- appcompat_v7_9
- appcompat_v7_10
- appcompat_v7_11
- appcompat_v7_12
- appcompat_v7_13
- appcompat_v7_14
As soon as I open these files,all the errors in my app were vanished !
If It till then didn't work then do Project -> Properties -> Android -> Is Library -> Add.. -> And add appcompat_v7_*
I had a very similar problem to this after I had used force to close Eclipse.
When I then restarted Eclipse, I noticed a number of "appcompat_v7..." folders in my workspace directory. I deleted these - and maybe that was the cause of this problem.
But I resolved it by creating a new Test project in Eclipse, then restarting Eclipse to find all my projects compiled again! :)
I didn't need to change any project properties.
this solution worked for me:
The support library android-support-v4.jar cause this conflictand you see the error: The import android.support.v7.app.MediaRouteActionProvider cannot be resolved, just delete the library under /libs folder of your project, because the library is already contained in the library appcompat_v7, clean and build your project, and your project will work like a charm!
