Android Build not possible

[Arne_B_1]

Hi,

I have a problem with the build of an android App. I think the problem is the "Using plattform Android-Cordova".

Please help me.

Are you able to build blank Android (Optimized with Crosswalk) projects successfully?

Hi Arne,

Have you taken a look at your compile log? It looks like one of your assets  is not a PNG file.

:mergeReleaseResourceslibpng error: Not a PNG file

There were jpgs in my project. I converted them to png. But the error is still there. Do I have to delet the project files from the server?

Arne -- you shouldn't have to delete the project from the server, but it wouldn't hurt. You can start with using the little garbage can icon on the build page. If that doesn't work, login to App Center to delete all entries. See this FAQ > https://software.intel.com/en-us/xdk/faqs/general#apps-in-development

I have no more ideas where a wrong asset can be found. Do you have some more advices?

@Arne -- how did you convert your JPG files to PNG format? Renaming them will not convert the internal format. You have to use a conversion tool or open the JPG files in an image editor and then save them as PNG formatted files. If that is what you did, it may be that the tool you used saved them in some obscure PNG format that is not being recognized.

It's hard to tell from your error message where this icon.png file is coming from (is it from your app or from a plugin). Can you provide a copy of the <project-name>.xdk file in the root of your project directory so I can see what plugins are part of your app. Also, if you could provide a ZIP of the icon image files that are in your project. Please ZIP them all together and post the ZIP as a file attachment to your next post (see the "Attach Files to Post" link below the edit window.

It works! I thought renaming is enough. ^^'

Thanks for help!
