i have drawing view, , trying array of bytes view on button click

this code:

public void onclick(     drawview.setdrawingcacheenabled(true);                 string imgsaved = mediastore.images.media.insertimage(                         getcontentresolver(), drawview.getdrawingcache(),                         uuid.randomuuid().tostring() + ".png", "drawing");         } } 

please help!

if view imageview first convert bitmap convert byte array

convert imageview bitmap

public static bitmap getimageviewasbitmap(imageview imageview) {         imageview.builddrawingcache();         bitmap bmap = imageview.getdrawingcache();         return bmap;     } 

convert bitmap byte array

public byte[] getbitmapasbytearray(bitmap bitmap) {         bytearrayoutputstream outputstream = new bytearrayoutputstream();         bitmap.compress(compressformat.png, 0, outputstream);         return outputstream.tobytearray();     } 

convert byte array bitmap

public static bitmap getbytearrayasbitmap(byte[] bitmap) {         bitmap bm = null;         try {             bm = bitmapfactory.decodestream(new bytearrayinputstream(bitmap));         } catch (exception e) {         }         return bm;     } 

to call these methods that:

provide imageview give bitmap

bitmap m1bitmap= getimageviewasbitmap(myimageview); 

provide bitmap give byte array

byte[] mbytearray =getbitmapasbytearray(mbitmap); 

provide byte array give bitmap

bitmap m2bitmap= getbytearrayasbitmap(byte[] bitmap);
