byte转化为Bitmap,防止内存溢出

 

Java代码

ByteArrayInputStream is =new ByteArrayInputStream(byte[]);
BitmapFactory.Options options=new BitmapFactory.Options();
options.inPurgeable = true;
options.inInputShareable = true;
options.inSampleSize = 2;
try {
    BitmapFactory.Options.class.getField("inNativeAlloc").setBoolean(options,true);
} catch(Exception ex) {
    ex.printStackTrace();
}
Bitmap imgBit = (new WeakReference(BitmapFactory.decodeStream(is, null, options))).get();
