converting pixels array in bitmap for Android

Question

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

@Tokiroto yes I have already looked at it - but it is not my problem since I need to create a bitmap from a pixel array and not from a path — epsilones

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);
