I am trying to convert image object to bitmap, but it return null.
image = reader.acquireLatestImage();
ByteBuffer buffer = image.getPlanes()[0].getBuffer();
byte[] bytes = new byte[buffer.capacity()];
Bitmap myBitmap = BitmapFactory.decodeByteArray(bytes,0,bytes.length,null);
The image itself is jpeg image, I can save it to the disk fine, the reason I want to convert to bitmap is because I want to do final rotation before saving it to the disk. Digging in the Class BitmapFactory I see this line.
bm = nativeDecodeByteArray(data, offset, length, opts);
This line return null. Further Digging with the debugger
private static native Bitmap nativeDecodeByteArray(byte[] data, int offset,
int length, Options opts);
This suppose to return Bitmap object but it return null.
Any tricks.. or ideas?
Thanks
You haven't copied bytes.You checked capacity but not copied bytes.
ByteBuffer buffer = image.getPlanes()[0].getBuffer();
byte[] bytes = new byte[buffer.remaining()];
buffer.get(bytes);
Bitmap myBitmap = BitmapFactory.decodeByteArray(bytes,0,bytes.length,null);
