When I extend a View, I cannot access the protected member variables from my code. Eclipse just says that there exists no variable with that name (for instance mScrollX). Why is that?

Before I delve into it, I'm very new to Android and I have just started learning Java last month. I've hit bumps while trying to develop my first simple app. Most of these hurdles were jumped thanks to random tutorials online. MY CODE IS VERY MESSY. Any tips are appreciated.
The question above is quite broad, but this is what I want to do: It's a essentially a blood alcohol content calculator / drink keeper-tracker. Basic layout: http://i.imgur.com/JGuh7.jpg
The buttons along the bottom are just regular buttons, not ImageButtons (had problems with that) Here's some example code ..
It outputs the following to the text view: "Your BAC is -0.017". This is the Bac value for if StandardDrinks was still 0, so obviously there is some problem communicating between the classes.
The other elements of the formula (weight, time spent drinking, and the alcohol %'s and such) are variables because I will ultimately allow the user to change those values in the settings.
I've heard around the water cooler that global variables are not good programming style, but this is the closest I've come to getting it to work..
I have an Android activity running with a custom view in it. When something happens within that custom view, I want to tell the currently running activity by changing one of the Activity member variables. Is there a way to access the current running activity member variables from within a custom view class besides passing the activity into the view class though a function arg?

My question now is: how to store values of variables so I can access them on the other tabs? I want to create something similar to sessions in PHP where I can save variables on one page and access on the other.

View 2 Replies View RelatedI'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", "my password");
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?
Be aware folks Rooting your Evo makes copy-protected apps "disappear" from the Market. I never had this problem on my rooted N1, however once I rooted Evo - it cannot see apps like NYTimes, bTunes, and basically any other app that's copy protected. I have read on XDA-forums that this has something to do with Market being affiliated with 'build.prop', but unclear as to what the fix for this will be, if any Right now, I am thinking of going back to stock because of this..
View 6 Replies View RelatedWe have a website that makes use of OAM for single sign on (form-based authentication). When we submit credentials to WebGate / Access Server the authorization succeeds, however after the authentication is performed, the form action (as configured in the Authentication Scheme - with passthrough:no) returns a server error instead of redirecting to the originally requested URL.
If we use Mini Opera, we are able to get authenticated and forwarded properly.
This problem happens on numerous Android phones (versions ranging from 1.5-2.2), as well as the Emulator provided with the SDK.
This is proving to be a real problem as the default browser on Android phones is not able to get access to our sites(and this is the only browser that is having this problem).
I have created a WebView-based custom browser with the hope of seeing a client-side error and tried trapping every possible error....none show up....
I have tried to trace all of the http requests and found only a single difference in the requests... the http header for Connection:keep- alive is not sent by the Android WebView.

Someone mentioned that protected apps will not appear until the eris is registered with the 2.1 android market. Just a heads up if you decide to upgrade early.
