The class starts the camera preview and takes a picture. Then I have a subsequent Intent start on the same Activity class to stop the preview. The second Intent will fall into the OnNewIntent. It also carries a set of extra parameters that I want to read and use iwthin the OnNewIntent. How do I access those Extra params? I have used Extra bundles before and I know how they work. So what do you mean I need to remember the Intent? What do you mean by servlet? Do you mean a Service? This design seems questionable to me. Trying to communicate with an existing activity like this is fraught with peril -- what if the user pressed home, you are popping yourself on top of whatever they are now doing; what if they pressed back, you are launching a new instance; what if they went down deeper in your activity stack, you are now doing ghod knows what to the stack by pushing at it from the service. Generally if an activity wants to find out about state changes from a service, it binds to the service and receives callbacks from it in any of a number of ways -- through messengers, aidl, PendingIntent to deliver a result, etc. Or if this is all one app running all one process, just have a singleton that keeps track of the service and your activity can get it to see if it is running and add a java interface callback for state changes. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

[android-developers] Copying Application Files on android device and apk versioning Information
HI, How we can make the apk(on installing) copy the application files on the device .Do we have invoke the script from the application to copy application files(test files,read me, release notes, data files) or is there any other way for example any default folder we have to put the files in and while installing the apk those files will get copied. Also is there a way to provide the versioning to the apk so that when we make some changes to the apk and install it it will incrementally update the existing one. What other benefits can there be for providing the versioning information embedded inside the apk. if any one has developed for windows , they can understand the versioning and application file copying(which we used to put under the file system) which on installing the application will copy the contents on the program files /application directory.

The infrastructure would need to support incremental purchases - and wouldn't THAT bring idiot users out of the woodwork. You know, the ones who already blame you for the Market's vagaries. It does sort of support incremental purchases through in-app billing. You could have an 'upgrade to tablet' item, and when they buy it, let them download the tablet APK. However, the developer console supports targeting by device, screen size, etc. only, not by purchased items, so not really doable. In any case, if you have two different packages already, you could release a separate 'for tablets' version with a higher price tag. You'll lose ratings, etc., but I've heard that a lot of App Store devs are going this way for iPad apps. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Just in section
On Aug 10, 11:50 am, John Coryat cor...@gmail.com wrote: Even if you can get traffic for being new, its only momentary. But it's a start There was a huge negative side effect of that just in category. Developers would make an update every week for no other reason than to appear at the top of that list. As a result, users tended to ignore the fact that an update was available. This user attitude is now a problem for legitimate updates. Hopefully, by eliminating the advantage of posting an update solely for the purpose of gaming the just in category, people will start to actually download the update when it becomes available and finally get over this attitude problem. I'm very glad to see that category gone. If it ever does come back, I hope it really is for new apps only. That would make a lot more sense to the users and keep developers away from playing that silly game. And cause developers to play a sillier game. Instead of the developer of Hot Korean pole dancers wallpaper issuing an update to get on the list, they will republish it as new app - Hot Korean pole dancing wallpaper. This will not only pollute the New apps category, it will add huge numbers of redundant apps to the normal market. It is a fact of life that the just In category gave new apps the kickstart which allowed them to gather a few ratings and a bit of profile. It is fine to say that there should be more targetted advertising outside of the market, in places where people who might need your app will find it. Where would you do that for a LWP which shows pretty patterns (as many of them do)? If the Market was working properly, and connecting prospective purchasers with sellers (the purpose of a market), then we wouldn't be discussing how to overcome its obvious limitations. It is interesting to compare Apple's and Google's approaches. Apple (and Amazon) enforce minimum quality standards on apps. Google does not. Because of this, the Android Market gets flooded with a lot of crap. Well, Android now has more (free) apps than Apple, and has certainly achieved critical mass. But this quantity has been at the expense of average quality. So, if 100,000 apps are released a year, how to you structure a market so that users find good new apps, and good app developers make money? The most obvious thing to do is reduce the number of new apps by not allowing crap to be uploaded. Just disallowing apps that manifestly break copyright law would be a good start. No, you cannot show film loops from movies, use cartoon, game or other characters created by other people, use sporting team logos, or use other peoples music or sounds without permission. Android apps should not be little more than web links. Enforce these rules, and in the LWP category would probably get half as many new apps, doubling opportunities for legitimate independent developers. Of the rest, 50% are knock-offs of existing apps, 40% of ther rest are just garbage. Enforce those rules, and the Just In category will work for everybody, devs and users, even if it includes updates. The cost of having somebody spend 5 minutes checking this basic stuff for all new apps would be less than $10 ph; levy a fee of $10 for every new app uploaded. Google are also fooling themselves if they think that the comments and ratings system accurately informs purchasers. In my category of wallpapers, I get a large number of 1 star ratings from users who claim it did not install, when in fact they just don't know where to find LWPs, despite me providing instructions. (Surprising, because I am well down the list, and I can't imagine that mine is the first LWP they have unsuccessfully tried to run ..). More commonly, they bitch about some feature being missing when it isn't, or just miss the point. My suggestion: Google uses anonymous reviewers, analogous to peer review. They would need about 1,000 volunteers. Each of these is asked to review on average one new app a day, and each app is reviewed by 3 volunteers completely independently. Nobody knows who the reviewers are. So that's 250 per volunteer per year, 250,000 reviews, each new app is reviewed 3 times, that's 83,000 new apps a year. These reviews are available as a seperate tab in the Market. I doubt that Google would have much trouble finding 1,000 volunteers, purely for the interest and on-line glory (albeit under a psuedonym). If any of the panel reveal their identity, or misbehave in any way, their reviews are expunged from the database. Having three reviewers each acting completely anonymously would allow systemic differences in scoring, or fraud, or competence to be detected automatically. Setting all this up shouild be quite easy; a new tab on the market for Our user panel said:, a bit of database programming to send each app to 3 active reviewers in that market category, and a bit of open source/cloudsourcing blah buzz to motivate reviewers. As a review system it could run entirely in parallel with what is done now

[android-developers] Best Way to Retireve, Display and Use 2 Values in a ListView from a JSON Array?
I have been able to retrieve one value from a MySQL database, display it in a ListView and use that value in a setOnItemClickListener method. Now I would like to retrieve two values, one that will be displayed in the ListView that makes sense to the user and a second one that will be used as to launch another operation when the item is selected in the ListView. I have found an example that extends the base adapter that looks like it will allow me to do this, but I was wondering if there was a easier way using the default functionality of the ListAdapter to accomplish what I want. thanks -- You received this message because you are subscribed to the Google Groups Android Developers group.

Ignore Android 1.5 for new development. Use the Android Compatibility Library for fragments. If you stick with just toolbar buttons and the standard options menu, the action bar is completely backwards compatible without any version-specific Java code. Use the multiple APK support to ship your current 1.5-compatible APK as-is to 1.5 devices. And so far, there are still about as many 1.5 devices out there as Honeycomb tablets However, there are more Honeycomb tablets being sold today than new 1.5 devices, and there will be a slight uptick in Honeycomb once the oft-delayed Android Market support for Google TV arrives.

[android-developers] Styling Honeycomb EditText's when inputType is specified
Ok, I've just noticed some oddities with honeycomb ui... and am sure its something I am missing... and hoping someone here has the answer. You know how in holo theme, the edittexts look diff depending on the inputType? Eg, if inputType=number, theres the bottom border, but no top etc. I am re-theming the edittext control, as the holo.dark edittext theme makes it very difficult to realize you are looking at a set of input fields. I am following this tut: http://www.androidworks.com/changing-the-android-edittext-ui-widget And honestly everything generally works pretty well (I dont use 9-patches, but rather shapedrawables). In any place I have inputStyle specified, the edittext doesnt take the style. I assume that honeycomb / theming system supports it as the holo dark theme absolutely styles the inputs differently... but I havent been able to figure it out. I've looked at honeycomb styles.xml and themes.xml, as well as the corresponding statelistdrawables, but have been unable to make it happen, and I'd prefer not to have to find every edittext and specify padding/background etc. Appreciate any pointers!

Re: [android-developers] Click an item in GridView programmatically
Hey thanks TreKing, I found one method, mGridView.performItemClick(view,position,id); It is calling the onItemClick method successfully.

As said by Mark, you can ignore anything below Android 2.1 as it is
irrelevant.
Android 2.1 is decling very fast an will be almost irrelevant in 6
months.
Tablet usage is on the rise. For the app I'm working on which supports
Honeycomb since
1 month or so, about 16-20% of my users are running Honeycomb, half of
thme using an Asus Transformer.
If you support android 2.0+ you rarely need reflection. You can use
conditional execution of code instead:
if(android.os.Build.VERSION.SDK_INT =
android.os.Build.VERSION_CODES.GINGERBREAD) {
// GINGERBREAD+ API calls valid here
list.setOverScrollMode(OVER_SCROLL_ALWAYS);
}
ActionBar compatibility on 2.x can be achieved with the great
ActionBarSherlock.
Anyway, making an app working on 2.1+ and having specific Honeycomb
support (action bar, multipane display, ...) is a *lot* of work.
It could be useful if it allowed to have a BETA version of an app
alongside a STABLE version.
This would be nice, too. But it would require a choice by the user,
while the current support is to allow the same app for different
configurations.
Indeed it would have serious complications for Google to implement.
That's why it probably
won't happen ever.

[android-developers] WebView Scaling behavior vs UIWebView in iOS
I am having some difficulty getting the Android WebView object to properly scale my content. In iOS, the UIWebView object has a scalesPagesToFit property which automatically scales content to fit the boundaries of the UIWebView. In my case, the content contains a number of absolutely sized/positioned items. I am easily able to re- size the UIWebView in code, and as long as the aspect ratio is the same as the body element of the html, the content is properly scaled to fit perfectly. On Android, this is proving to be much more difficult. I have tried to manually set the WebView's initialScale, which works at first. However, since the layout automatically changes the position/size of the WebView, the scale gets changed by itself to a value I don't want (as observed in the onScaleChanged event). Once this happens, I am trying to manually change initialScale to my desired value, but it doesn't trigger a change on the WebView. The appearance does not change, and the onScaleChanged event is not fired. I thought perhaps setting user-scalable to false would stop the automatic scaling done by the WebView, which it does seem to do, but it also prevents me from manually changing the scale myself. Any advice would be extremely helpful, I've been at this for a while. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Android Location Update every 30 seconds
I can't really help you with your main problem but you might want to watch out for this. The phone can and cannot be in use even when the accelerometer is moving fast or not moving. Example 1: The user is walking with the phone in his pocket. Creates a sizable amount of movement but phone is not really in use. Example 2: The user is walking while texting. Sizable amount of movement plus activity. Example 3: Device is on the table and not in use. No movement plus no activity. Example 4: User is sitting and texting.

[android-developers] Help me!!!
Hello, I'm trying to find a way to rotate a View, or (more conveniently) an entire layout, upside down and have it stay that way. I found the rotation and animation classes in the SDK, and these come close to what I want, but at the end of the animation I want my Layout to stay rotated; repeating the animation or just flipping back right- side-up doesn't help me with my app unfortunately. The only thing I can think of so far would be to find the source code for the rotate class, and override it such that the ...and then flip it back around to be right-side-up code never happens. I'm not sure exactly where I'd find the original rotate code for reference if I were to do something that extensive however. I've found references online to the full android source - is that basically what I'd be looking at downloading to be able to attempt something like this? Am I missing a simple option on the rotation that would let it just stay put after I rotate it? Any help would be very much appreciated!

Upper textview's color is orange and lower textview's color is
blue ,but both textview's background colour is white.
Now I want to reverse the color with background color on focus
It means selected list item's upper textcolor will be of white color
and its background color will be of orange. and lower textview's color
will be of white and its background will be of blue whenever the list
item's get focus.

There are some solutions: - Flip the device once to portrait orientation, after that, the menu does appear.

Why?
Please help me!

[android-developers] [Dalvik] JIT profiling
In the IO 2010 presentation guys from Google's Dalvik team showed profiling capabilities of their JIT compiler. This capability could be enabled with 'dalvik.vm.jit.profile=true' in system properties. But I can't profile JIT on GB and HC. Moreover I can't find 'dalvik.vm.jit.profile=true' processing somewhere in the Android tree. It was there in Eclair but then was removed. Interesting thing is that Dalvik VM by itself supports '-Xjitprofile' keyword but crashes somewhere in code cache. Also, another interesting capability is JIT statistics (you should send 'kill -12 pid' to your process) is also inactive and simply kills your application. Are there are any ways to profile JIT somehow? Or it was not very usable and was removed from latest releases? I need to figure out which native code is generated for my Java code, is it possible to do it somehow? Thanks a lot!

[android-developers] Hidden WebView
Hi, I'm kinda new to Android. I have my main view, and I need to create and run a hidden WebView in the background. Can someone help me with that?

[android-developers] Activity Flow Brain Teaser
Hi All, I have been learning about the complex problem of Activities, launch flags, Intent flags, tasks and the Activity stack. I've been trying to solve what I thought would be a simple problem. Our application has a Search Activity that can possible be entered through two paths: 1) ServerListActivity SearchActivity 2) URLLaunchActivity SearchActivity In both cases, the same SearchActivity should be reused because the user may have gone beyond the search to other activities, and we want to 'pop the stack' back to the SearchActivity if they are launching from a URL. The URLLaunchActivity is set up to handle VIEW intents, and it basically forwards those intents on to the SearchActivity. I have implemented special handling for the VIEW action in both onCreate of SearchActivity as well as onNewIntent. I have added android:launchMode=singleTask to the SearchActivity manifest entry, which makes sure that the same SearchActivity is always used when handling the intents. This is the only flag I could use to make this work even partially correctly. Any other flags were not what I wanted at all, unless I have missed something fundemental in my learning stages -- a probable thing, as this is complicated stuff. Because we are searching for patient data with this application, we need to comply with HIPPA requirements and have a timeout associated with the SearchActivity so that if the application is idle for long enough, the SearchActivity will finish and display a dialog to the user stating that there was a timeout. This is where I seem to have trouble. Because a new Task is started when the SearchActivity is launched, the usual startActivityForResult method will not work because the intent is immediately cancelled due to the new task being started. Okay, so I've had to come up with a static flag on the SearchActivity to signal that the timeout had occurred so the dialog can be displayed to the user when returning to either the ServerListActivity or the URLLaunchActivity. This isn't terrible, but it is unexpected. The only clue to this behaviour was a small LOG statement from the ActivityManager and the immediate callback of the onActivityResult with a cancelled flag set. The real problem is that I want to make sure that if the application is launching a URL, URLLaunchActivity launches SearchActivity and I want the application to exit back though that same stack always. What I am seeing is the following strange behaviour: App Launch - ServerListActivity - SearchActivity | User long presses HOME and switches to Browser User clicks on link in browser - URLLaunchActivity - ServerListActivity | Inactivity Timeout Occurs | ServerListActivity The timeout occurs, and the ServerListActivity is returned to, not the URLLaunchActivity as desired. That surprises me greatly. Some extra information that might help anyone interested enough to still be awake at this point in my story: - In URLLaunchActivity the intent flags FLAG_ACTIVITY_CLEAR_TOP and FLAG_ACTIVITY_SINGLE_TOP are used when launching SearchActivity. - I noticed that in ServerListActivity I am NOT setting either of those flags. Perhaps this is leading to this bad behaviour? I've read all of the documentation (that I know of) on the subject, and thought I had a grasp of what's happening. But I'm still not sure. Is there any advice on how I might simplify this scenario? Thanks in advance for any insight. -Neal -- You received this message because you are subscribed to the Google Groups Android Developers group.

No = time to learn. If you can, then write one, marrying it with Android SDK and that's it. You can ask specific question to specific groups of people. Find Red5 user group and JUV RTMP user group and ask them. This groups is about Android SDK and RTMP streaming is off topic, unfortunately.
