I have a webview and I am using android:configChanges="orientation" to restrain the webview from reloading everytime the orientation changes.I also have two different folders layout-port and layout-land to define the layouts for different orientations.If I use android:configChanges="orientation" then the above two folders are ignored. Can I have both working at the same time?

Just started working with the webview. The issue is performance following rotation. The WebView has to reload the page, which can be a bit tedious.What's the best of of handling an orientation change without reloading the page from source each time?

I have a widget , thats working just fine in a particular orientation, but the moment i change the orientation to landscape/portrait, the widget is not able to launch. I have one layout and one layout-land folder in res directory.The problem is that the widget created in landscape mode is not opening in portrait mode and vice-versa.

I've been developing for Android for three months now, and for the first time I'm working with the new 1.5 SDK.
I'm facing a pretty basic problem with the WebView. I'm following the HelloWebView tutorial (here: http://developer.android.com/guide/tutorials/views/hello-webview.html) and when I'm launching my Activity, the page opens on the browser and not in my app!
I tried everything, but I don't have a clue of the reason. Anyone faced the problem and knows how to solve it? Code...

I've racked my brain for hours over this issue. I have created a main.xml and designed one for the res/layout-land (landscape) format and another one for portrait in res/layout. When I rotate the emulator (ctrl-F11), my app rotates properly to landscape using the correct main.xml, but a subsequent rotation back to portrait just keeps the landscape mail.xml. This was done in a 2.0 AVD.. Out of desperation I downloaded the new Sample Code for Multiple Resolutions and had to create a new 2.1 AVD, to my surprise rotation with this app works correctly as expected. So I then decided to try my app on the 2.1 AVD and it works perfectly. So, is this a Bug in a 2.0 AVD or is there something special I need to be doing for < 2.1 SDK versions?

I have created a webview with a transparent background. Code...
Here is the JavaInterface that should change the color of the background when the html form is submitted and all the checkboxes pass the test. Code...
This does not work however, and the returned document still has a transparent background. What am I doing wrong, it seems that browser.setBackgroundColor(Color.WHITE); does nothing?

I have a webview in my app that generally works fine for loading websites. But I cannot get www.gmail.com to work: when I open www.gmail.com I see the login page, try to login, afterwards the screen goes black and my app/process is killed. I don't see much in my logcat, just some strange debug information is being dumped as below. But generally https sites work fine, and even more complicated login procedures like opening stackoverflow.com, logging in via openid through https, back to stackoverflow, all work without a problem in my webview. Only gmail.com is giving me these problems.......

I have a WebView in my layout which I want to display a web page in. However the webpage requires Basic Authentication.
If I try to access this web page in the normal android browser, I get prompted for a username and password which then gets remembered and works for the site in future.
I want to do the same thing in my application, but when I load the page into the webview it just comes straigt up with the Unauthorized message without prompting.
I guess the prompting for Authentication is written in code in the android browser. Does anyone know how to inject a username and password into the WebView?
I have done a search arond and found the setHttpAuthUsernamePassword (String host, String realm, String username, String password) Method, But can't seem to get it to work and I can't find anyone else who has either? Not sure if I am giving it the correct parameters as I'm a little confused by what is means as the Realm?
I assumed that if the site was myhost.dyndns.org then the hostname would be myhost and the realm would be dyndns.org? This didn't seem to work. I also tried connecting by IP Address but that makes the Realm setting even more confusing? Any ideas on how I can get this working?

I have a WebView that displays a complex graph. My problem is that the webview will only scroll a few pixels instead of scroll horizontal all the way so I can view the entire graph. How can I make it so my WebView is able to be scrolled all the way to the right/left to view the entire webview content? I tried putting a ScrollView around my WebView but it did the same thing.

I download some data from internet in background thread (I use AsyncTask) and display a progress dialog while downlaoding. Orientation changes, Activity is restarted and then my AsyncTask is completed.I want to dismiss the progess dialog and start a new Activity. But calling dismissDialog sometimes throws an exception (probably because the Activity was destroyed and new Activity hasn't been started yet).What is the best way to handle this kind of problem (updating UI from background thread that works even if user changes orientation)? Did someone from Google provide some "official solution"?

I am developing part of an Android application that needs to use a WebView to open a password protected site. I am using SharedPreferences to provide the username and password from when the user logs in the app for the first time. I've tested the credentials it's returning, so I know that those are correct. When I run this in the emulator, the site says that I'm unauthorized (even though I am). Here's the code...
So does anyone know why this wouldn't be authenticating me? Should the realm string that I put "" for actually be something?

I'm the proud owner of the HTC Magic on Vodafone UK. I'm loving the Android.I have to say that after 5 days of owning this device I'm only left scratching my head on one point the auto-orientation of the home screen.I've seen videos of rooted G1's running the hacked 1.5 firmware and the recently posted video of the Samsung i7500 with the 1.5 firmware all CLEARLY show that when the device is on home screen, the desktop (read home screen) auto-rotates depending on the orientation of the device. The Samsung video shows it working in ALL FOUR orientations!This doesn't happen on my Magic . Flip the orientation in an application? Works fine. Flip it back in an application? Works fine. Do it on the home screen?Am I missing something? Is this a feature that is disabled in the offical 1.5 Cupcake release? If that's the case - fine with me. I'll stop scratching my head and move on.

How to make the following phone's magnetic and orientation sensor working? Both of these sensors are not working on my phone (verified by many apps such as Z-deviceTest, AndroSensor and Android Sensor Box).
Various applications have shown that this phone has 5 sensors :
- yamaha530 Orientation Sensor : 0.25 mA by Aichi Steel
- yamaha530 3-axis Magnetic Field Sensor :0.25 mA by Aichi Steel
- bma222 3-axis Accelerometer : 0.13 mA by The Android Open Source Project
- tmd2771 Proximity Sensor : 0.13 mA by Capella
- tmd2771 Light Sensor : 0.13 mA by Capella
Phone name : Clone Samsung Galaxy III S9300
Manufacturer : alps
Model: e1901_v77_jbl1_9p017
CPU: MTK6577 Dual Core 1.0GHz
Android version : 4.1.1
Baseband version : MAUI.11AMD.W12.22.SP.V15,2012/10/08 20:09

Build Number : e1901_v77_jbl1_9p017_20121105
Perhaps there is new ROM or kernal that can handle the sensors better?

I have created an activity for my game which handles all orientation changes by itself and has a fixed "portrait" layout. Actually it uses the accelerometer and is rendered using 2D canvas methods. If the level has been completed I show up a highscore dialog in which the user can enter his name. The dialog is floating above the underlying level screen which gets blurred out nicely. This generally works.
Problem is that the dialog does not get rotated if the orientation of the phone changes. So even if the keyboard is exposed the dialog is shown in portrait mode instead of landscape. I have tried to use an activity with dialog theme instead but the behavior didn't change. After several tries it seems that I have found the reason for this: Once there's an activity with fixed orientation in the activity stack then all subsequent activities keep this orientation, too. They will not react on orientation changes anymore (e.g. if the keyboard gets exposed).
After upgrading to 1.5 SDK the described behavior changed a little bit. Now at subactivities indead react on orientation changes like expected. However, the need to have an opaque background! That means that neither dialogs nor activities with dialog theme will work. Those will stick with the orientation of the underlaying activity. So my workaround is to first start a sub-activity with an opaque black background. This activity then shows my highscore dialog on top. It looks quite okay but I wonder if there's a better solution? Is it possible to show a dialog above a fixed portrait or landscape activity which automatically adapts to orientation changes?

I understand how to force a specific orientation per activity in the android manifest. I would like to know if it is possible to allow the keyboard to change orientation even though the activity(the layout really) must remain unchanged.

I have a WebView in my Android App that is loading an HTML string using the loadDataWithBaseURL() method. The problem is that local anchor links (<a href="#link">...) are not working correctly. When the link is clicked, it becomes highlighted, but does not scroll to the corresponding anchor.
This also does not work if I use the WebView's loadUrl() method to load a page that contains anchor links. However, if I load the same URL in the browser, the anchor links do work.
Is there any special handling required to get these to work for a WebView?
I am using API v4 (1.6).
There isn't much to the code, here are the relevant parts of some test code I've been working with:

I have a problem with working with the ORIENTATION values of the SensorManager. I would like to have some kind of 360°-value which directly shows me if the phone is in normal portrait (0°), landscape, portrait turned around (180°) or anything in between. So I could have, for example, an arrow that points to the floor (like gravity would do with a plummet) all the time, no matter how I tilt (sidewards) the phone. I thought this would be easy, but I'm pretty confused at the moment.
First of all, the X value of the orientation-array seems to correspondent with how I turn the phone, BUT: if it's completely uprightly standing, this value is about 60° ... why not 0° (or 90°, 180°, 270°), as I would expect?
Second: The value resets if I turn the phone and Android automatically changes screen orientation. So both in Portrait and in Landscape mode it will be sth. like 60° when the phone is in a 0° angel in real world. I set "android:screenOrientation" to "landscape" but this doesn't help anything :/
I want the app NOT to change orientation when I turn the phone, but I want it to get a continuous orientation value when I tilt the phone.

I would a Tab (in a TabHost) to have a Landscape orientation while the activity with the TabHost is in Portrait orientation, is that possible (if so how)? I tried setting the orientation of the Activity displayed in the tab in the Manifest but it didn't work.

I figured that I can have custom layout for each orientation just by making two folders layout-port and layout-land. So I put different views in these folders. Worked well.
Now, I have a webview in my activity and it reloads whenever there is any change in orientation. So to prevent that I put android:configChanges="orientation" in my manifest file.
After putting this the reloading stopped but the contents in the layout-port started getting selected for landscape mode as well.

i have a layout folder with 2 layouts. layout1 and layout2 i have another folder layout-land that has layout1 in it. i would like to be able to get to all the layouts so i could create a set of layout like this: {layout1, layout2, layout1(from layout-land folder)}is there any way i can use the existing android mechanisim to do that? if not, what would be the impact of creating my own definition of the layout folder (for example to have under the layout folder layout1, layout2 and layout_land1 and have my code do getOrientation to diffrentiate whcih one should be presented).

I've built an app widget a fairly simple one that draws an image inside a frame. (If that sounds familiar, that's because it's very similar to the built-in one, but it's a start to something else.)The RemoteView consists of little more than a FrameView and an ImageView. I have a second FrameView that may display or not depending on some certain state awareness.The Image updates on an Alarm schedule rather than the built-in mechanism so the user can adjust this value after installation. The image is set on the RemoteView using a drawable ID from included resources in the package. They've been resized to approximately a quarter of the screen size, but might still be scaled a little by the ImageView.All of this has been working fine. There is one issue that I've been unable to diagnose even the root of the problem.
After an orientation change when the home screen redraws, the ImageView doesn't always draw. The rest of the RemoteView does draw just as it was set during the most recent Update.The mystery is that the ImageView does, in fact, draw if the Alarm is currently set. If it's not currently set, it doesn't draw. Nothing else seems to affect whether it draws or not. It doesn't matter if the widget process is running or not, either (killing it via DDMS and then rotating has the same effect).This occurs in the emulator as well as the G1. During a rotate, the widget gets no update event at all.I could set it to listen for configuration changed broadcasts, but since it works in one of the cases, I suspect something else is going on and that's just an unnecessary piece of duct tape.

My underlying actitvity is set to landscape orientation, but when I show the dialog, I'd like it to be in portrait (vertical) orientation.I set the orientation in my layout to be vertical but that didn't help. The Dialog class doesn't have a method for such a thing.

From the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest:
Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change.
Why does it say this?
In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity.
While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself.
Why should it be avoided?
I guess I should also ask: would this be an acceptable reason for doing the orientation configuration changes yourself?
