I'm trying to make a screenshot. Suggested a couple of methods

protected Bitmap MakeScreenshotOfView(View v) { Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.RGB_565); Canvas c = new Canvas(b); v.draw(c); return b; } public static Bitmap getBitmapFromView(View view, int totalHeight, int totalWidth) { Bitmap returnedBitmap = Bitmap.createBitmap(totalWidth,totalHeight , Bitmap.Config.RGB_565); Canvas canvas = new Canvas(returnedBitmap); Drawable bgDrawable = view.getBackground(); if (bgDrawable != null) bgDrawable.draw(canvas); else canvas.drawColor(Color.WHITE); view.measure( View.MeasureSpec.makeMeasureSpec(totalWidth,View.MeasureSpec.EXACTLY), View.MeasureSpec.makeMeasureSpec(totalHeight,View.MeasureSpec.EXACTLY)); view.layout(0,0,totalWidth,totalHeight); view.draw(canvas); return returnedBitmap; }

Both work on simple screens, where not a lot of View. But I need to make a screen of such a screen:

enter image description here

It is dynamically filled with small imageview. Then comes the animation. At the end of the animation I try to make a screen, he thinks and then gives out OOM.

The first two lines are repeated many times with different values ​​and then crashes. HELP !!!

  • one
    Try adding the android:largeHeap="true" attribute to the application tag in the manifest. This is not exactly the right decision, but if it works - the simplest one is Vladyslav Matviienko
  • Tried - does not help. I would just like to understand what could be the matter. Not to say that I eat a lot of memory, the usual frame, dynamically add to the layers of pieces 20 image view with a total size of 1Mb ... - Fox
  • And the phone is rutted? If so, try something in the spirit of Process p = Runtime.getRuntime().exec(new String[]{"su", "-c", "/system/bin/screencap -p /sdcard/img.png"}); - pavel
