Multiple accounts on separate web windows? (Android)
I'm new to Android development and I have a question about how WebView processes data (in Java).
I am guessing this will fall under the "cookie" category. But I have two different webViews in different tabs of my application. I would like to have one webview (call it webView1
) listed in one website account and the other ( webView2
) in another account of the same website. For example, I would like to log into two separate Gmail accounts in two web windows at the same time.
The problem I am facing is that after logging into an account on webView1
, webView2
follows suit and logs me into that account. The same problem occurs when logging in webView2
, since logging webView1
into this account is also natural.
Is there a way to get around this? I want my two webViews to act completely independently of each other, that's what it boils down to.
Thank!

I can definitely answer your question. I am basically an iOS developer and I am creating an Android app with the exact opposite effect that the WebView cookie does not use. I created my tabbed webviews to mimic the behavior I use on iOS, but my web elements act completely independently of each other. I want them to have the same login information, but since it costs, I have to log into each tab individually, because they don't play well.
Anyway, my problem can definitely help you and I hope you share your information with me to create the cookie sharing effect I'm looking for ...
Here is my layout main.xml:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="@+id/web_engine"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:layout_marginTop="-45dp" />
<WebView
android:id="@+id/messages"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:layout_marginTop="-45dp" />
<WebView
android:id="@+id/myprofile"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:layout_marginTop="-45dp" />
<WebView
android:id="@+id/rncorner"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:layout_marginTop="-45dp" />
</FrameLayout>
</LinearLayout>
</TabHost>
Here is my activity:
package com.example.tabs;
import android.app.TabActivity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.TabHost;
public class TabsActivity extends TabActivity {
WebView webView;
final String DEFAULT_URL = "http://example.com";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost mTabHost = getTabHost();
mTabHost.addTab(mTabHost.newTabSpec("Home").setIndicator("Home",getResources().getDrawable(R.drawable.home)).setContent(R.id.web_engine));
mTabHost.addTab(mTabHost.newTabSpec("Messages").setIndicator("Messages",getResources().getDrawable(R.drawable.messages)).setContent(R.id.messages));
mTabHost.addTab(mTabHost.newTabSpec("My Profile").setIndicator("My Profile", getResources().getDrawable(R.drawable.myprofile)).setContent(R.id.myprofile));
mTabHost.addTab(mTabHost.newTabSpec("Map").setIndicator("Map", getResources().getDrawable(R.drawable.rncorner)).setContent(R.id.rncorner));
mTabHost.setCurrentTab(0);
//home
webView = (WebView)findViewById(R.id.web_engine);
webView.setWebViewClient(new MyWebViewClient());
webView.loadUrl(DEFAULT_URL);
//messages
webView = (WebView)findViewById(R.id.messages);
webView.setWebViewClient(new MyWebViewClient());
webView.loadUrl("http://example.com/index.php2");
//my profile
webView = (WebView)findViewById(R.id.myprofile);
webView.setWebViewClient(new MyWebViewClient());
webView.loadUrl("http://example.com/index.php3");
//rncorner
webView = (WebView)findViewById(R.id.rncorner);
webView.setWebViewClient(new MyWebViewClient());
webView.loadUrl("http://example.com/index.php4");
}
public class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
}
