Is there a way to keep users logged in even after restart without saving username and password locally?. I just want to pause the session when the app is closed then resume when it is opened.
Tried both:
myWebView.getSettings().setDomStorageEnabled(true);
myWebView.getSettings().setAppCacheEnabled(true);
Also tried CookieManager and managed to do what I want but for some reason, it stopped working and keeps logging out users when app exits(I'm still new and I do not know what happened and am not able to fix it). So I'm trying to find a different approach to do this.
My MainActivity.java:
public class MainActivity extends AppCompatActivity {
public DrawerLayout dLayout;
private WebView myWebView;
public ActionBarDrawerToggle actionBarDrawerToggle;
public void setActionBarTitle(String title) {
getSupportActionBar().setTitle(title);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
setTitle("Updates");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//CREATE A FOLDER
File file = this.getBaseContext().getExternalFilesDir("downloads");
if (!file.exists())
file.mkdir();
setNavigationDrawer(); // call method
dLayout = findViewById(R.id.my_drawer_layout);
actionBarDrawerToggle = new ActionBarDrawerToggle(this, dLayout, R.string.nav_open, R.string.nav_close);
dLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
// to make the Navigation drawer icon always appear on the action bar
Objects.requireNonNull(getSupportActionBar()).setDisplayHomeAsUpEnabled(true);
myWebView = findViewById(R.id.activity_main_webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.getSettings().setDomStorageEnabled(true);
myWebView.getSettings().setAppCacheEnabled(true);
myWebView.setWebChromeClient(new WebChromeClient());
String url = "http://192.168.43.105/public_html/central/updates.php";
myWebView.loadUrl(url);
myWebView.setWebViewClient(new WebViewClient());
myWebView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView webView, int errorCode, String description, String failingUrl) {
Toast.makeText(MainActivity.this, "Oh no! " description, Toast.LENGTH_SHORT).show();
}
public void onPageFinished(WebView webView, String url) {
CookieManager.getInstance().flush();
}
});
myWebView.getSettings().setSupportZoom(true);
myWebView.getSettings().setBuiltInZoomControls(true);
myWebView.getSettings().setDisplayZoomControls(false);
myWebView.getSettings().setUseWideViewPort(false);
}
