我有一个可以经常调用的活动，该活动采用闪屏的形式，显示图像并在 3 秒后完成。但是，如果频繁第二次调用，活动会崩溃。

下面是代码片段：

public class SplashActivity extends Activity {
    private long splashDelay = 3000; //3 seconds

    ImageView imageView = null;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle b = getIntent().getExtras();
        int value = b.getInt("key");


        imageView = new ImageView(this);
        imageView.setImageResource(Utility.getImageIDofGalleryAlphabets(value));
        setContentView(imageView);


        TimerTask task = new TimerTask()
        {

            @Override
            public void run() {
                 BitmapDrawable bitmapDrawable  = ((BitmapDrawable) imageView.getDrawable());

                    if (null != bitmapDrawable && !bitmapDrawable.getBitmap().isRecycled()) {

                        bitmapDrawable.getBitmap().recycle();
                    } 
                    bitmapDrawable = null;
                imageView = null;
                finish();

            }

        };

        Timer timer = new Timer();
        timer.schedule(task, splashDelay);
    }
}

以下是运行时异常：
