import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.BitmapFactory.Options;

public class Main {
    public static Bitmap getBitmap(String filePath) {

        Options options = new Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(filePath, options);

        Boolean scaleByHeight = Math.abs(options.outHeight - 100) >= Math
                .abs(options.outWidth - 100);
        if (options.outHeight * options.outWidth * 2 >= 16384) {
            double sampleSize = scaleByHeight
                    ? options.outHeight / 100
                    : options.outWidth / 100;
            options.inSampleSize =
                    (int) Math.pow(2d, Math.floor(
                            Math.log(sampleSize) / Math.log(2d)));
        }
        options.inJustDecodeBounds = false;
        options.inTempStorage = new byte[512];
        Bitmap output = BitmapFactory.decodeFile(filePath, options);
        return output;
    }
