I have a 262144
(512*512) one dimensional pixel int[] pixelsArray
array taht I want to convert into Bitmap
and display it in an Android
app, so I put
bitmap = Bitmap.createBitmap(512, 512, Bitmap.Config.ARGB_8888);
bitmap.setPixels(pixelsArray, 0, 512, 0, 0, 512, 512);
I get this message
java.lang.IllegalArgumentException: bitmap size exceeds 32bits

I tried some SO
solutions, but none worked. Could someone help ?
here's the answer that worked :
bitmap = Bitmap.createBitmap(512, 512, Bitmap.Config.ARGB_8888);
byte[] byteArray = new String(pixelsArray).getBytes("UTF-8");
BitmapFactory.Options thumbOpts = new BitmapFactory.Options();
thumbOpts.inSampleSize = 4;
bitmap = BitmapFactory.decodeByteArray(byteArray, 0, pixelsArray.length, thumbOpts);
