Gradle project sync failed.
After update the android SDK I got this error:
Error:Failed to find: com.google.android.gms:play-services:5.2.8
I use
compile 'com.google.android.gms:play-services:6.1.+'
Even though it warns against it. If things go flakey after an update I'll revert back to the current version.
You can now use
compile 'com.google.android.gms:play-services:6.1.11'
Suggesting using Open File> Project Structure, click the "add (+)", searching for "play-service" to select the currently available version. Something like this image: http://i.stack.imgur.com/9Pv7j.jpg
I had the same problem. I solved using:
compile 'com.google.android.gms:play-services:7.0.0'
Check your sdk extras packages, you need to install:
For me, the thing was that I didn't have the second one installed and then "---:5+" worked as described here:
https://developers.google.com/mobile-ads-sdk/docs/admob/android/quick-start
try using com.google.android.gms:play-services:5.2.08 instead of 5.2.8.
you can also look for the right version number in your services directory:
.. /android-studio/sdk/extras/google/m2repository/com/google/android/gms/play-services/
