Android位图-内存不足

Question

I have a problem with a function that I implemented. On some phones I get a out of memory error.

private Bitmap getIconMarkerOfPlayer(Player p) {
    Drawable drawable = getIconOfPlayer(p);
    Bitmap img = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_4444);
    Canvas canvas = new Canvas(img);
    drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
    drawable.draw(canvas);

    final float scale = this.getResources().getDisplayMetrics().density;
    int heigthPixels = (int) (24 * scale + 0.5f);
    int widthPixels = (int) (24 * scale + 0.5f);
    return Bitmap.createScaledBitmap(img, widthPixels, heigthPixels, false);
}

The getIconMarkerOfPlayer(Player p) function gives a "programmed" drawable depending on the player's status (dead, alive, offline, ...) and its color. Each player has a unique color assigned to it in the early games.

How can I resize my bitmap from a Drawable object without having a out of memory error?

Answer 1

I suggest you to use some ImageLibraries to load Bitmaps efficiently.

Some of them are Fresco , Glide , Piccasio .

I suggest you to go with Glide . Have a look at it here
