android手机按下home键后如何避免应用重启

Question

I am implementing an android app with Xamarin.

I performed the following step.

1. Start the APP

2. The APP opened with first page "A"

3. Pressed a button and go to page "B"

4. Pressed home button on mobile phone.

5. Click on the APP icon to go back to the APP.

6. The app looks like restart and opened in page "A"

Why would this happened? How could I avoid this.

I have checked my android manifest file.

There is no "android:launchMode" item.

I had the same issue, and in my code, "NoHistory" was set true in MainActivity.cs. So I changed it to false:

    namespace [YourAppName].Droid
    {
        [Activity(..., MainLauncher = true, NoHistory = false, ...]
        public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
        {
...

My app literally resumes when I select the app after pressing a home button. I'm wondering if your case is the same as mine.
