I'm trying to do basic authentication to view a protected url. I want to access the protected url which looks like this:
http://api.test.com/userinfo/vid?=1234
So I do the following with a WebView:
mWebView.setHttpAuthUsernamePassword("api.test.com", "", "me#test.com", "mypassword");
mWebView.loadUrl("http://api.test.com/userinfo/user?uid=53461");
but the authentication doesn't seem to work, I'm just getting an output error page. Am I using the WebView method correctly here?
Update:
Trying with curl:
curl -u me#test.com:mypassword http://api.test.com/userinfo/user?uid=53461
and it pulls the page fine. I tried every combination of the host parameter, the owners of the api don't know what I mean by 'realm' though (and neither do I) - what info could I give them to help this along?
Thanks
Another option is to use a WebViewClient;
webview.setWebViewClient(new MyWebViewClient ());
private class MyWebViewClient extends WebViewClient {
#Override
public void onReceivedHttpAuthRequest(WebView view,
HttpAuthHandler handler, String host, String realm) {
handler.proceed("me#test.com", "mypassword");
}
}
webview.setWebViewClient(new WebViewClient () {
public void onReceivedHttpAuthRequest(WebView view,
HttpAuthHandler handler, String host, String realm) {
handler.proceed("login", "pass");
}
});
The default behavior of a WebView is to discard all authentication requests. Even if setHttpAuthUsernamePassword.
You have to set a WebViewClient and Override the method onReceivedHttpAuthRequest
If you do not mind writing your username and password into the url, then it is not necessary to change your webview client.
Just open the following url in the webview:
http://username:password#api.test.com/userinfo/vid?=1234
In this example realm is By Invitation Only
AuthType Basic
AuthName "By Invitation Only"
AuthUserFile /usr/local/apache/passwd/passwords
Require user rbowen sungo
You may need something other than "" for the second parameter. Contact the developer of the Web site and find out what an appropriate realm should be. Or, use tools like curl to find out what the realm should be.
I never did get setHttpAuthUsernamePassword to work with phonegap's FileTransfer.download (since it doesn't use the webview), but I DID get this to work with phonegap. It's worth noting if any other phonegap people end up on this thread.
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, pass.toCharArray());
}
});
This is so silly. I hacked something together that worked for me, I hope it'll work for you too.

Try using shared preference for this issue
following step will help you
step 1. Initialize at top
private static final String PREF_FILE = "PREF_FILE";
private static final String IS_PRODUCT_PURCHASE = "IS_PRODUCT_PURCHASE";
step 2. inside onProductPurchased() method add these line
SharedPreferences.Editor editor = getSharedPreferences(PREF_FILE, MODE_PRIVATE).edit();
editor.putBoolean(IS_PRODUCT_PURCHASE,true);
editor.commit();
setp 3.call this method inside onCreate() at last
private void checkForIsPurchase() {
SharedPreferences preferences = getSharedPreferences(PREF_FILE, MODE_PRIVATE);
boolean isPurchase = preferences.getBoolean(IS_PRODUCT_PURCHASE, false);
if (isPurchase) {
Adview.setVisibility(View.GONE);
textView6.setVisibility(View.GONE);
}
}
I have a custom loading bar in my app, when used in my emulator the loading bar is displayed along with the text as defined in the layout with no problems, but when i run the app on my device the loading bar box comes up but it does not display the loading icon or the loading text, just a blank space.
Below is my custom bar class
public class csBar

public static csBar s_m_oCShowProgress;
public static Context m_Context;
public static Dialog m_Dialog;

s_m_oCShowProgress = new csBar(m_Context);
}
return s_m_oCShowProgress;
}
public void showProgress(Context m_Context)
{
m_Dialog = new Dialog(m_Context);
m_Dialog.requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
m_Dialog.setContentView(R.layout.custom_progress_bar);
m_Dialog.setTitle("Loading ....");
m_Dialog.findViewById(R.id.progress_bar).setVisibility(View.VISIBLE);

The CustomWebView class is so I don't get errors with loadData for the streaming site. I don't know why this class is working but it is. I copied it from the livestream support site, I'm only a newbie and I'm trying to learn.
If you're referring to these two lines of code at the top of your class:
// Button button = (Button) findViewById(R.id.home);
//final Button //final Button button2 = (Button) findViewById(R.id.contatti);
That will not work in that location. Those buttons are created in your XML layout. You cannot get a reference to a button declared in an XML layout before you first call setContentView() in your onCreate() method. You must do this.
This is what you need to do:
public class MainActivity extends AppCompatActivity {
private Button mButton;
private Button mButton1;
private Button mButton2;
// declare any other fields you require
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mButton = (Button) findViewById(R.id.home);
mButton1 = (Button) findViewById(R.id.stream);
mButton2 = (Button) findViewById(R.id.contatti);
// Your other initialization code
}
Please note that you cannot declare those Buttons as final fields, as they are not instantiated in a constructor (onCreate() is not a constructor).

The onConnected() callback is not called on the Main UI thread, but on a separate thread that is used by the Service. So it is not able to access the TextView created in Main UI thread. What you should do is create a Handler in the main UI thread and then use that handler to post a runnable that makes changes to the TextView. You can read more about Handlers on the Android developer site.
