I've coded an application which can post tweets and you can see user timelines and search timelines with it. I did that with the TwitterAPI and fabric.io. And if I want to generate an APK file or sync the Gradle file, I get these errors:

C:\Users\Alexander\AndroidStudioProjects\FacebookPlus\app\build\intermediates\res\merged\debug\values\values.xml

Error:(140) Attribute "srcCompat" has already been defined

Error:Execution failed for task ':app:processDebugResources'.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\Alexander\AppData\Local\Android\sdk1\build-tools\23.0.2\aapt.exe'' finished with non-zero exit value 1

app:srcCompat is an xml attribute usually applied to views like ImageView.

Maybe you declared that attribute twice in the same view.

  • Thanks for the answer! I will look in all my view and then i tell you the result – AleXoTroN May 17 '16 at 19:21
  • Alan_UK When I click on the error, I come every time on this path: "MyApp> app> build> Intermediates> res> Merged> debug> values> values.xml". Does that mean something? – AleXoTroN May 17 '16 at 19:36
  • You need to check your strings.xml file and remove all duplicated values you find, that may solve your problem – 92AlanC May 17 '16 at 21:27
  • But if i click on the error message i get to this file: "MyApp> app> build> Intermediates> res> Merged> debug> values> values.xml" and there i can find "" twice. If I delete one of them and rebuild the project, it automaticly generates again – AleXoTroN May 17 '16 at 21:49
  • Could you please post the contents of your values.xml? – 92AlanC May 17 '16 at 22:05
  • @AleXoTroN From what you're showing me, it comes from your Android SDK build tools. Try opening your SDK Manager and downloading a more recent build tools release. Then, on your ~/app/build.gradle file, change the buildToolsVersion attribute value to the version you just downloaded and then sync. That should work – 92AlanC May 18 '16 at 11:01

Answer for Alan_UK's request - I cant post the full content because it is too long. I only post the content which includes the dual attributes

I had this issue as well.

In my case, the problem was that the support libraries in my gradle file's dependency section should all be the same version.

More info here: Gradle error "Attribute "xxx" has already been defined" in Android Studio
