    Possible duplicate of [AAPT2 error: check logs for details](https://stackoverflow.com/questions/47589873/aapt2-error-check-logs-for-details) – Akhilesh Awasthi Feb 17 '18 at 13:34
  • First of all, you probably disabled AAPT2 with the android.enableAapt2 flag because you were getting errors from AAPT2. Now you're getting errors from AAPT1 - meaning there's something actually wrong with your resources. The errors should be visible in the full build log. If you're having trouble finding it, you can manually run it by going to the project directory and executing "./gradlew clean assembleDebug". – Izabela Orlowska Feb 19 '18 at 10:48
  • Yes, I see this error in my build after Android Studio was upgraded to 3.1 – cVoronin Mar 28 '18 at 05:34
  • You need to post your whole build log so we can see what the problem is. Run "./gradlew clean assembleDebug" in your project directory and post the output in the question. – Izabela Orlowska Apr 24 '18 at 13:15
  • Also try with a newer gradle plugin - 3.2.0-alpha11 or newer – Izabela Orlowska Apr 25 '18 at 13:16

    Sorry, but from what I have read this hides the warning but I am not sure if this will solve the actual issue. – rgv Jun 28 '18 at 18:16
  • (1) update android studio (2) restart android studio (3) set `android.enableAapt2` to true – flyingpluto7 Sep 10 '18 at 16:24

    Earlier was getting this error :The option 'android.enableAapt2' is deprecated and should not be used anymore. After making true getting this error :Error: java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: AAPT2 error: check logs for details – Tarit Ray Apr 05 '19 at 10:29

You can actually have problems in the resources but these will not be displayed if you do not correct this problem first:

The option 'android.enableAapt2' is deprecated and should not be used anymore. Use 'android.enableAapt2 = true' to remove this warning. It will be removed at the end of 2018.

within your gradle.properties file that is located in the root of the project, replace: 

android.enableAapt2

with: 

android.enableAapt2 = true

Your problem is with android.enableAapt2 .
You should check what's missing or the package is imported correctly. Search for file android.enableAapt2 or that keyword.

  • The "android.enableAapt2" message is just a warning, since AAPT1 will be deprecated soon and so disabling AAPT2 is not recommended. The real errors should be visible in the build log. – Izabela Orlowska Feb 19 '18 at 10:48
