Any pointers on what am i doing wrong or how i can resolve this.

Answer 1

droidtext uses parts of Apache Harmony for the awt dependencies. The ICC_Profile implementation of Harmony which gets used when a png image has a iCCP chunk (http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html#C.iCCP) is dependent on a native library. This native code isn't part of droidtext right now.

I opened an issue for it here: http://code.google.com/p/droidtext/issues/detail?id=6 and will look into it. Would be great if you could attach a png where this issue occurs to the bug.

As a workaround you can remove the color profile from the png or prevent droidText from applying it by uncommenting line 424-429 in PngImage.java

I had a similar issue, and I solved this way:

Check if your png image has some weird color profile. If you use photoshop to design png images, use "Convert to Profile..." and choose "sRGB IEC61966", and then when "Saving for Web" check the "Convert to sRGB" option.
