Android /drawable-nodpi/ loading scaled

I recently rebuilt my Android project to target 2.2 from 2.1. In the old project, I did not specify a target SDK (the manifest did not contain something like: android:minSdkVersion="8"). This gave me an error in the console when running, but everything worked fine so I didn't fool with it. The new project now uses android:minSdkVersion...

Help Refactoring working method To Load BitMap (Instead of File) To PHP Server ..

Problem with monochrome windows bitmap scanlines...

I am trying to figure out the format of a Windows bitmap file that is monochrome. From what I can tell, the scanlines are padded on the end to maintain DWORD alignment. However, any data I save is garbled like it's interleaved when viewed from mspaint. However, if the width and height of the image are the same, the data is not garbled wh...

Alternative to Bitmap.getPixel()

I remember a while ago reading about an alternative (aka faster) way to perform a "getPixel()-ish" method. Problem is, I don't remember where I read that, and I've searched thoroughly.. I think.
