Android将字节数组转换为Bitmap的最佳方法？

Question

I know why OutOfMemoryError Exception occurs.But there are any best way to convert byte array to Bitmap.And I used below code ,But when large byte it force close app and gives OutOfMemoryError Exception.

And i have API it just return me byte array nothing else.

Bitmap bmp = BitmapFactory.decodeByteArray(bytearray, 0, bytearray.length);

Answer 1

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapbytes , 0, bitmapbytes .length);

返回已解码的位图，如果图像无法解码，则返回null。

Answer 2

Here is what worked for me: photo is a string of an image by the way.

byte[] imgbytes = Base64.decode(photo, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(imgbytes, 0,
imgbytes.length);
imageupload.setImageBitmap(bitmap);

Answer 3

You probably have to use this following method ( DOC , same method, but with the options parameter):

public static Bitmap decodeByteArray (byte[] data, int offset, int length, BitmapFactory.Options opts)

And play with the options parameter. Hope this will help you =)

You may want to use the AQuery library to load your images, this will help you resize, view etc and avoid the most common memory leaks. This tool can be found here: http://code.google.com/p/android-query/
