为什么我的闪屏很长

Question

我试图在我的应用上实现启动画面。加载启动画面后，我有两个问题。 如果用户已连接，则启动活动。如果没有，则启动另一个。

但是，通过我的实现，当用户连接时，启动画面很长（8或9秒），但我不知道为什么。

这是我的第一个检查用户是否已连接的类，它是否加载了一些共享首选项？那也许就是这样呢？

public class AnnaActivity extends AppCompatActivity {

    public PrefManager pref;
    private AllRequest req;
    private static final String REQUEST_TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        this.pref = new PrefManager(getApplicationContext());
        boolean isco = pref.getIsConnect();

        if (isco) {

            Log.e("SPLASH", "IsConnected");
            Intent loginActivity = new Intent(this, NavigationDrawerActivity.class);
            startActivity(loginActivity);
            finish();

        } else {
            Log.e("SPLASH", "launch login activity");
            Intent loginActivity = new Intent(this, MainActivity.class);
            startActivity(loginActivity);
            finish();

        }
    }
}

这是我的泼水画
