转换像素阵列中的位图的Android

Question

我有一个262144（512 * 512）的一个维像素int[] pixelsArray阵列taht我要转换为Bitmap并在Android应用显示它，所以我把

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 
      at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2180) 
      at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2230)

我尝试了一些SO解决方案，但没有工作。有人可以帮忙吗？

这里是工作的答案：

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);
