How to know App navigating to HomeActivity or LoginActivity - Appium

I am testing my mobile app using Appium. When app starting it directly navigation to HomeActivity sometimes(if user already logged in). If user not logged in then opening LoginActivity.

So, how can I know which activity starting? so that I can execute logout code accordingly.

This code not executing at all because app navigation to HomeActivity directly instead of LoginActivity.

public void DemoTest()
{
    AndroidElement editElement1 = driver.FindElementById("input_name");
    editElement1.Clear();
    editElement1.SendKeys("ak@ct");
    AndroidElement editElement2 = driver.FindElementById("input_password");
    editElement2.Click();
    editElement2.SendKeys("qa");
    driver.HideKeyboard();
    driver.Manage().Timeouts().ImplicitWait =TimeSpan.FromSeconds(4);
    AndroidElement editElement3 = driver.FindElementById("btnLogin");
    editElement3.Click();
}
