OutofMemoryError in android while creating a bitmap from string path?

Question

I have a service using which i am changing android wallpaper. I am passing path of images to the service and then using following code to set the image as wallpaper:

@Override
public void run() {
    try {
        final String imagePath[] = mSelectedImgPath.split(",");
        while (true) {
            for (int i = 0; i < imagePath.length; i++) {
                bitmap = BitmapFactory.decodeFile(imagePath[i]);
                this.setWallpaper(bitmap);
                Thread.sleep(1000 * time);
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

I am getting following error:

Thanks

I am resizing the images before setting them as wallpaper as per the device screen size. I thing the issue is related to something else. — Ashwani Kumar, Jan 25 '13 at 10:37
I don't think so. the Log is clearly telling you, that you ran out-of-memory by trying to decode the Bitmap from its path. You should try to decode it with bounds, or maybe giving BitmapOptions a compression level lower than 100 — Rafael T, Jan 25 '13 at 10:43

Increase your "VM heap" if your running program in emulator. Goto avd manager and click on to ur android emulator and increase size VM heap.

Its because your images might be in big size, try to scale your images.

refer this Strange out of memory issue while loading an image to a Bitmap object

Use

bitmap.recycle();

just after entering the loop

  for (int i = 0; i < imagePath.length; i++) {
            bitmap.recycle();
            bitmap = BitmapFactory.decodeFile(imagePath[i]);
            this.setWallpaper(bitmap);
            Thread.sleep(1000 * time);
        }
