Something about processing images in Android

I will do some trial experience about image in Android programming. The list here will be updated once posted.

• Combine bitmap side-by-side
• Merge two image, overlap with Alpha
• Example to draw Bitmap with ShadowLayer
• Draw text on bitmap using Canvas.drawText()
• Merge images with PorterDuffXfermode
• Create frame on Bitmap image
• Create shadow frame for image
• Share bitmap between Activities
• Handle error of 'OutOfMemoryError' and 'Bitmap too large to be uploaded into a texture' for images/bitmaps
• Load scaled bitmap
• Fine tune scaled down bitmap to exact size
• Detect touch event and position on ImageView
• Get bitmap color on touched position in ImageView
• Detect touch and free draw on Bitmap
• Detect touch and draw rect on bitmap
• Create mirror bitmap with matrix
• Create upside down bitmap with matrix
• Convert Bitmap to Drawable with BitmapDrawable
• Combine bitmap, half/half
• Adjust HSV(Hue, Saturation and Value) of bitmap
• Scale bitmap with inDither and inPreferQualityOverSpeed
• Adjust saturation of Bitmap with ColorMatrix

The exercises have not take care the bitmap size, and any resizing. So don't test with big picture, otherwise OutOfMemoryError or "Bitmap too large to be uploaded into a texture" will happen.
