java.lang.ClassCastException: android.app.ContextImpl

I am trying to incorporate ScoreNinja into my little game: http://scoreninja.appspot.com/

However, a runtime exception is thrown every time:

The problem is probably ChickenPushupTimer.java:31.

Here is my entire Java file:

public class ChickenPushupTimer extends Activity
{
    int count = 0;
    TextView timeLeft;
    TextView totalPushups;
    ImageButton button;
    SoundManager mSoundManager;
    Vibrator myVib;
    ScoreNinjaAdapter scoreNinjaAdapter;

    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.chickentimer);
        scoreNinjaAdapter = new ScoreNinjaAdapter(getBaseContext(), "cockpushups", "71A7AD115870BA0E05C13BE2B9D3F984");

        myVib = (Vibrator) this.getSystemService(VIBRATOR_SERVICE);
        mSoundManager = new SoundManager();
        mSoundManager.initSounds(getBaseContext());
        mSoundManager.addSound(1, R.raw.chicken);

        timeLeft = (TextView) findViewById(R.id.timeLeft);
        totalPushups = (TextView) findViewById(R.id.totalPushups);
        button = (ImageButton) findViewById(R.id.chickenbutton);

        countdownTimer();

        button.setOnClickListener(new View.OnClickListener()
        {

            public void onClick(View v)
            {
                myVib.vibrate(250);
                count++;
                totalPushups.setText("" + count);
                mSoundManager.playSound(1);
            }
        });
    }

    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.popupmenu, menu);
        return true;
    }

    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        switch (item.getItemId()) {
        case R.id.goback:
            /*Intent myIntent = new Intent(getBaseContext(), MainMenu.class);
            startActivity(myIntent);*/
            finish();
            return true;
     //   case R.id.help:
     //       showHelp();
     //       return true;
        default:
            return super.onOptionsItemSelected(item);
        }
    }

    public void countdownTimer()
    {
        new CountDownTimer(16000, 1000) {

             public void onTick(long millisUntilFinished) {
                 timeLeft.setText("" + millisUntilFinished / 1000);
             }

             public void onFinish() {
                 scoreNinjaAdapter.show(count);
                 finish();
             }
          }.start();
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    {
        super.onActivityResult(requestCode, resultCode, data);
        scoreNi开发者_JAVA百科njaAdapter.onActivityResult(requestCode, resultCode, data);
    }
}

This is line 31:

scoreNinjaAdapter = new ScoreNinjaAdapter(getBaseContext(), "cockpushups", "71A7AD115870BA0E05C13BE2B9D3F984");

There may be something wrong with the context I am using. Any help would be GREATLY appreciated!!

If you look at the code for ScoreNinjaAdapter here, it shows that it casts the context to Activity. Try using this instead of getBaseContext, since you're calling from an activity.
