Not the same error message, but very similar (mergeDebugResources vs mergeDebugAssets), you might find something usefull there:

Error compiling the ionic on android

[brianvandelden]

Already tried to remove the android platform and add it again?

[prosenjit_itobuz]

I try to remove and add again but problem not solved.
Also I have only one SDK

[TobiasS]

Did you ever fix this problem? I’m running into the same problem. Seems that /drawable-port-xhdpi/screen.png is not generated during the build proces. Therefore the build error’s once trying to read it. It seems the size is however properly generated by ionic in resource/android so I don’t understand why only this sizes is not correctly copied during the build process.

[prosenjit_itobuz]

My problem was solved. When I removed platform and generated resources and restore state by ionic state restore and generate again resources by ionic resources

[my101du]

I solved this problem.

It was because of the “ionic resource” service error.

where run “ionic resource” command, I looked into and checked the /resources/android/splash folder, I clicked and open all of these png files, I found some pictures were broken(which appears as half of it).

So I replace these broken png files with the “normal” png file(at the same folder), then run “ionic build” command， the error is disappeared.

thanks, i solved my problem by your solution.

actually, we can run ‘ionic resource --icon’ or ‘ionic resource --splash’ to regenerate these files.

while Building i am getting the following error…

Please any one give me a solution for this problem

This is how i solved my Error

1. I wanted to set splash screen
2. and i had SPLASH.jpg image
3. and i just changed extension to splash.png
4. and it started giving error
5. then i i kept normal png which worked fine
6. then i added ALPHA CHANNEL with photoshop to image SPLASH.jpg and saved as SPLASH.png
7. then error was

so moral of the story is don’t just change file extension blindly to make it work … if you want to change extension use photoshop or use any online website image format converter
