Wallpaper not properly fit on device screen

Question

I have one set of images in one drawable folder. I have one button to set image as wallpaper on device screen. But when I set this image as wallpaper its either zoom or crop

Answer 1

Try this code:

public void changeWallpaper(String path) {
        FileInputStream is;
        BufferedInputStream bis;
        WallpaperManager wallpaperManager;
        Drawable wallpaperDrawable;
        File sdcard = Environment.getExternalStorageDirectory();
        try {
            is = new FileInputStream(new File(path));
            bis = new BufferedInputStream(is);
            Bitmap bitmap = BitmapFactory.decodeStream(bis);
            Bitmap useThisBitmap = Bitmap.createBitmap(bitmap);
            wallpaperManager = WallpaperManager.getInstance(getActivity());
            wallpaperDrawable = wallpaperManager.getDrawable();
            wallpaperManager.setBitmap(useThisBitmap);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

In this example , I have used image from my device SD card...

It's perfectly worked for me..
