OOM解决办法

1. private Bitmap decodeFile(File f){
2. ? ? Bitmap b = null;
3. ? ? try {
4. ? ?? ???//Decode image size
5. ? ?? ???BitmapFactory.Options o = new BitmapFactory.Options();
6. ? ?? ???o.inJustDecodeBounds = true;
7. ? ?? ???BitmapFactory.decodeStream(new FileInputStream(f), null, o);
8. ? ?? ???int scale = 1;
9. ? ?? ???if (o.outHeight > IMAGE_MAX_SIZE || o.outWidth > IMAGE_MAX_SIZE) {
10. ? ?? ?? ?? ?scale = Math.pow(2, (int) Math.round(Math.log(IMAGE_MAX_SIZE / (double) Math.max(o.outHeight, o.outWidth)) / Math.log(0.5)));
11. ? ?? ???}
13. ? ?? ???//Decode with inSampleSize
14. ? ?? ???BitmapFactory.Options o2 = new BitmapFactory.Options();
15. ? ?? ???o2.inSampleSize = scale;
16. ? ?? ???b = BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
17. ? ? } catch (FileNotFoundException e) {
18. ? ? }
19. ? ? return b;
20. }
