Android - Application restarting after minimization [closed]

Navigation
0

I have an android application, where I only have one screen that gets a WebView. However, when the user accesses a page of the site, for example: mysite.com.br/contact and minimizes the app. When he reopens the app, instead of returning it on the page it's on, it goes back to the home page (at miite.com). I have already added events to update the variable that modifies the url, to modify it when the url is modified. I have also added events to save the state of the application and still the same error continues.

To prevent the app from "restarting" after minimizing, you should save the instance

For this you should use the methods onSaveInstanceState , onRestoreInstanceState and super.onCreate in your Activity .

It would look something like (read the comments in the code): 

public class MainActivity extends Activity {
    private WebView meuWebView;//Seu webView

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);//"super" envia o comando para classe "parent"
        ...
    }

    @Override
    protected void onSaveInstanceState(Bundle outState){
        super.onSaveInstanceState(outState);//Salva Activity 
        meuWebView.saveState(outState);//Salva WebView
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState){
        super.onSaveInstanceState(savedInstanceState);//Restaura o Activity 
        meuWebView.restoreState(savedInstanceState);//Restaura o WebView
    }
}
