Error:Execution failed for task ':app:mergeDebugResources'. > Some file crunching failed, see logs for details build gradle issues

Question

currently I am using Android Studio 2.1 when I run my App it shows me some error in Message Gradle Build saying the following

I tried cleaning and rebuilding it but it didn't work. The answer for this question didn't work also. Any help would be appreciated, thanks.

Updated: Here is the log output

Answer 1

cd adroid
./gradlew clean

worked for me

Answer 2

Actually, image file something wrong. Go to (drawable) and remove image or replace with new image.This will solve problem.

In addition, you can put method in (build.gradle), but This will not solve the problem but good way to catch up what was wrong.

In build.gradle, section android {}, insert aaptOptions { cruncherEnabled = false }.

Answer 3

I tried everything above mentioned but couldn't find anything. Then I backed up my code and reverted to last runnable commit, after that i copy/pasted my code back to original piece by piece and added the files again and i found out the problem. I did <item>Driver's License</item> which i changed to <item>Driver\'s License</item> inside string array in strings.xml file.

Answer 4

I hope this is helpful to someone.

I had the same error and tried the code sample below as well as deleting my .grade, to deleting my .build and .idea which didn't work.

aaptOptions {  
    cruncherEnabled = false  
}  

I later discovered what was causing the error.

If the error wasn't caused by changing an image file extension manually. I suggest to check your strings or array.xml and make sure you aren't using a single quote without having backslash before the single quote.

Error:

Côte d'Ivoire

Fix:

Côte d\'Ivoire

Answer 5

In my case I have deleted all PNG files in res folder and then I have reinstalled that and it works for me

Answer 6

I have the same error too. But it has fixed now.

The main problem is some Gradle files are corrupted. I have deleted entire .gradle file and run the project again. This time it got worked!.

When I run after deleting .gradle file, it automatically repaired the Gradle files as shown below:

LOG IN DEBUG CONSOLE:

This seems like the library is partially migrated. Jetifier will try to rewrite the library anyway.

I was facing the same issue checked all the related answer but my problem was not solved. I added a new folder drawable to add icons in my app. So after deleting that folder my problem was resolved. Also, clean the Gradle your problem will be resolved.

cd android && gradlew clean
cd .. && react-native run-android

Also, there may be some data which is corrupted like images you have added, try to remove those images may it work.

Answer 8

On react native

When you're inside your project directory try using :

$ cd android && gradlew clean

$ cd .. && react-native run-android

Answer 9

For me, I was getting this error because the full path to the folder was longer than allowed by Windows. I moved my build to a shallower path and this error went away.
