    GridView gridview = (GridView) findViewById(R.id.gridview);

    public ImageAdapter(Context c) { 
     mContext = c; 
    }

のみ2のものは確認して、あなたのGridViewにnullを返しているあなたのコード行は、私のカウントをラインアップならば、それはfindViewById()のように見えます...ですそれはあなたのレイアウトに記載されています。次に、splashScreenでThread.stop()を呼び出しているように見え、Dalvik VMではThread.stop()が実装されていません。
