OOM解决办法

手动进行垃圾回收   调用bitmap.recycle() 或者System.gc();

If you use them for fit-in screen display only, just scale them to the 
screen-size. You don't need any bigger. 

1. Figure out the actual width and height of the image 
(inJustDecodeBounds = true) 
2. When actually loading the pic, downsample (inSampleSize > 1) so 
that the resulting image fits the screen as good as possible (for best 
result, make the loaded image a bit bigger than the screen instead of 
a bit smaller). Also, the values of inSampleSize work best across most 
phones when its value is a power of 2 (2, 4, 8, etc) 
3. Then scale the image (down) a bit further to exactly fit the 
screen. 

E.g. say your screen is 800x400. Your image is 2048x1536. Then 
downsample the image (inSampleSize = 2) --> Loaded image is 1024x768. 
Then scale the downsampled image by 52.08333% --> a bitmap of 533x400 
pixels. Cache this image. Still, be careful not to cache too many 
images.
