Android onNewIntent Uri is always null -

in activity's onnewintent() method, getintent().getdata(); null. goes method before going oncreate() or other lifecycle function. returns here browser, don't know why getintent().getdata() null though.

this activity starts browser context.startactivity(new intent(intent.action_view, uri.parse(requesttoken.getauthenticationurl())));

and returns here

@override public void onnewintent(intent intent){     super.onnewintent(intent);      uri uri = getintent().getdata();     if (uri != null && uri.tostring().startswith(twitterconstants.callback_url)) {...} } 

but uri null.

manifest stuff:

  <activity         android:name="myapp.mypackage.tweetformactivity"         android:configchanges="orientation|keyboardhidden"         android:label="@string/app_name"         android:launchmode="singleinstance"         android:screenorientation="portrait"         android:theme="@android:style/theme.black.notitlebar">          <intent-filter>             <action android:name="android.intent.action.view" />             <category android:name="android.intent.category.default" />             <category android:name="android.intent.category.browsable" />             <data android:scheme="oauth" android:host="myapp"/>         </intent-filter>         </activity>  static final string callback_url = "oauth://myapp"; 

what missing here? thanks

you should call getdata() intent argument or perform setintent(intent) before obtaining uri. onnewintent() doesn't set new intent automatically.

update: so, here're 2 ways can implement onnewintent(). first replaces old intent new one, when call getintent() later, receive new intent.

@override protected void onnewintent(final intent intent) {     super.onnewintent(intent);     // here we're replacing old intent new one.     setintent(intent);     // can call getintent() , receive new intent.     final uri uri = getintent().getdata();     // uri... } 

the second way use data new intent leave old 1 as-is.

@override protected void onnewintent(final intent intent) {     super.onnewintent(intent);     // not call setintent() new intent,     // have retrieve uri intent argument.     final uri uri = intent.getdata();     // uri... } 

of course, can use combination of 2 variants, do not expect receive new intent getintent() until explicitly set setintent().
