This is because your PNG file is not supported or else you renamed your file directly   Do the following steps    Copy your image source file from Android Studio to your desktop  Open the file with Paint  Save file as extension  png Delete the existing source file from Android Studio which you copied  Add the newly created file which you renamed via Paint    Problem solved

The best answer is already given in the gradle output     Try  Run with --stacktrace option to get the stack trace     Open the Terminal in Android Studio and run gradlew  app mergeDebugResources --stacktrace   In my case it was the Windows 240 char limit   but it should give you the root cause for any other issue just as well

In my case I reached the solution in two steps    Keep your project name  package name  folder names short  because if the directory name exceeds 255 characters it gives the mergeResource error  Keep your drawables in the drawable folders  Any drawable file such as  jpg and  png outside the drawable folders throws the mergeResource folder error

To solve this problem you should use drawable -  new -  image asset and then add your images  You will then find the mipmap folder contains your images  and you can use it by  mibmab img

I am also suffering from the same issue  In my case I just copied the image to the drawable folder  then Android Studio is showing the error  Some file crunching failed    My problem regarding to image only because that image was saved from the one of the my customized camera application in  png format  And for testing purposes I copied it into the drawable folder   After that I tested saving the image as  jpg  It was not giving any error  That means the camera by default supports the   jpg  format   Finally I realized two things    The camera by default supports the   jpg  format Without using image tools  don t change the image formats  even programmatically

I got this issue after migration to Gradle 3 3  on Windows  with gradle-2 14 1 everything was fine    The problem was in the path to the Gradle build-cache  which contains Cyrillic characters  like  C  Users       android build-cache   So I renamed the user s folder to  Ivan   and the problem was gone

I tried to rebuilt  restart  clean  update Gradle  etc  However  none of them worked for me   Sometimes  it can be caused by a wrong naming for an XML or resource file   At least  for me  that problem was solved by changing the name

User · Answer

For me  it was a corrupted PNG file   Go to your res folder and try to open every image  When you find an image which can t be opened  replace it with a good image

In my case  I solved this problem by simply changing my library file as I made a silly mistake of adding two different versions of the same library   As this can be due to varied reasons  I found out the following ways to solve this issue as per the problem    Mismatch of resources Missing attributes  wrong tags  etc  in resources Issue in styles Missing name in styles Duplicacy of resources and libraries Sometimes it can even be solved by changing the compatible library in build gradle Executing the aapt command Renaming the extension from  jpg to  png Simply with the help of Clean Project    Even in some cases  restarting Android Studio can solve the problem

It seems to be a nasty problem of Gradle  We just upgraded from 2 14 to 3 3 and our build server couldn t build any more  a local build in Android Studio worked    Error with too long path shows for example      C  Windows System32 config systemprofile gradle caches 3 3 scripts-remapped build bonsjy48fqq8sotonpgrvhswt 36ejadunoxgw3iugkh95lqw projedd7e29570ae79482d0308d82f4e346b classes build bonsjy48fqq8sotonpgrvhswt  run closure1  closure8  closure13  closure14  closure15 class   We had to create a local user account for the service that ran as system service for years    Now it saves under C  Users    which is much shorter as the system profile path

In my case the solution was simple  I moved the entire project to another location where the path is short   The problem was caused by long directory names and file names

I had put my images into my drawable folder at the beginning of the project  and it would always give me this error and never build so I    Deleted everything from drawable  Tried to run  which obviously caused another build error because it s missing a reference to files  Re-added the images to the folder  re-built the project  ran it  and then it worked fine    I have no idea why this worked for me  but it did  Good luck with this mess we call Android Studio

I fixed this issue by moving the project to the outer directory  and it then compiled successfully   It was due to the long path of the project directory   For example  I moved the project from    D  Android Apps AndroidStudioProject AppName   to  D  Android AppName

I noticed downgrading Gradle build tools to 1 2 3 solved my problem of the Crunching PNG error  but on 1 5 0 the problem continues

User · Answer

The Crunching process is the image preparation process  which means something is wrong with your image files  In my case I had a PNG file which was not really a PNG file  My solution  I converted all my images to PNG running a super simple Python script from within the image folder  so in total all you need to do is   In order to install the PIL library  run  pip install pillow  Save the below Python code in a  py file within your images folder you want to convert   Adjust the from format  to format variables in the script to whatever you need   Run script  python script name py import os from PIL import Image  from format     quot  jpg quot    quot  png quot    quot  bmp quot   to format    quot png quot   for fn in os listdir            if os path isfile fn  and fn lower   endswith from format           print  quot Converting File   s quot    fn         im   Image open fn          im save fn split      0          to format  to format upper       And if you want read more about the Image module  http   effbot org imagingbook image htm

For me  it is because one of my  png files is actually a  psd file  Resave it to real PNG file  and it is fixed

This error was caused for me because of the path where my project was located  There was a blank space in one folder  for example   Folder Another Folder MyAndroidProjects       Changing it to Folder AnotherFolder MyAndroidProjects     and resynchronising Gradle resolved this for me

User · Answer

In my case  I believe this issue was to do with the length of the file path  UNIX and Windows systems impose a maximum path length of 255 and 260 characters respectively  and I believe the crunch process fails when assigning to a dynamically-specified path  So  even if the quoted path lengths in the error message are shorter than the limit  mine was only 187 within a Windows build environment   I think the crunch utility may internally specify a longer path  even if just temporarily   You may determine whether this is the source of error by moving your project to the root-most directory on your file system  then attempt recompiling

In my case  the error was caused by a PNG file I added to the drawable folder  I had changed its extension from jpg to png by changing the text  in an inproper way  and then uploading it as PNG   This was the problem Android Studio was pointing to   I fixed this problem and got the error to disappear by changing the file extension using the Paint NET tool or any other tool  proper way   and then uploading it to the drawable folder

Just add this to your local properties file of your project   BUILD DIR C    Tmp    The error in Windows is due a long path  so I gave the path to one temporary folder

User · Answer

The best solution is to change buildDir in build gradle   For example   allprojects       buildDir    C  tmp   rootProject name    project name       repositories           jcenter             Rebuild and happy coding

I faced this problem when I copied my images  no matter JPEG or PNG  into the drawable folder manually  There might be different kinds of temporary solutions to this problem  but one best eternal way is to use the Drawable importer plugin for Android studio   Install it by going to  menu File   Settings   Plugins   Browse Repositories   search  Drawable   You ll find Drawable importer as the first option  Click install on the right panel   Use it by right clicking on the Drawable resource folder and then new  Now you can see four new options added to the bottom of the list  and among those you will find your appropriate option  In this case the  Batch drawable import  would do the trick

User · Answer

This is due to adding an image in drawable which has some extension like   jpg   and you have changed or saved that to a  png format  this error will occur while changing the image format manually without using an editor tool    Android Studio will throws an error while compiling the resource package using AAPT  Android Asset Packaging Tool   so all you need to do is use some image editor tools like GIMP or Paint to save the extension accordingly  Rebuild your project once everything is done   For example  open your image in Paint  drag and drop your image to open it    menu File   Save As   Save as Type   select your required type from the dropdown like I have shown in the below pictures

I changed the location of the app and copied it to a short path   You can do that by just copying your project and pasting it to a new Short Location  And  it worked for me   For example    Old path  c  user android studio project your app New path  c  your app

I have faced this problem also  and it has not been solved by reformatting the image although it was an image from a project app of Google  and it was only solved by   Moving the project file to the partition directly   Try it  It might help you

Closing Android Studio and opening again solved this issue in my case    Give it a try  I know it is not the right solution or answer  but it works  I am not sure about the root cause  It would be great if someone can share that
