Re: [android-developers] Re: Android libraries
Hmm this should be handled by the plugin indeed. To be honest, the way the current plug-in create the linked folder is not great. We've made it much more robust in the next version (coming soon).

Re: [android-developers] Debugging power management - how to determine cpu state?
It is difficult, because attaching to USB keeps a wake lock held. You can use adb shell dumpsys batteryinfo to see the current stats about your app, which includes the time spent holding each wake lock. (You'll probably want the last section of output, which is the time since last unplugged.) Note that the wake lock times are weighted, so if two wake locks are being held at the same time they will be accounted as using 50% of the overall time. Also, of course, you could log when you acquire and release the wake lock and then look at the log after plugging in again. adb logcat -v time gives logs with time stamps. H... that said, if you just care about what you are doing with your own wake locks, it doesn't matter if the device is kept awake while plugged in to USB, and you can use adb shell dumpsys power to see what wake locks (if any) you are currently holding at that point in time.

Unfortunately the exception could only happen in Home when it ultimately tries to persist itself, which is long after the app is involved, so any exception would result in home crashing. Fwiw, the API to turn an Intent into a URI string (which is the only form that is safe to put in persistent storage) is this: http://developer.android.com/reference/android/content/Intent.html#toUri(int) http://developer.android.com/reference/android/content/Intent.html#toUri(int)It certainly should explain more about the limitations on the extras that are supported. :} For now, here is the source code where you can see the types it handles: http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/java/android/content/Intent.java;h=2acc4a05792ae50f5c03c92749bcf35072ccea64;hb=master#l5379 http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/java/android/content/Intent.java;h=2acc4a05792ae50f5c03c92749bcf35072ccea64;hb=master#l5379 On Sun, Aug 29, 2010 at 12:44 PM, Bob Kerns r...@acm.org wrote: Thanks for the heads-up.

I'm glad there's an option to fix it. From the look of things our Launch configuration requires a workspace build before launch.

Re: [android-developers] Re: Is there a way to request permissions from a user as you need them?
Separating some code into a separate .apk doesn't really improve security, it's only a way for the user to adjust his/her comfort level. There is nothing preventing two separate .apks, one with read contacts and the other with internet permissions to do exactly the same as one malicious app, steal contact info. It might not be obvious to the user at all that the two apps are working together to do something bad. The only way this is meaningful is if the application to pick a contact is well known and trusted, which probably means it should be part of Android itself. I believe what would help is finer-grained access permissions, splitting a broad read contacts into smaller-scope permissions, based on user-driven scenarios. Perhaps it should be done with other permissions, such as write external storage.

[android-developers] Re: Is there a way to request permissions from a user as you need them?
Interesting debate. And from a technical perspective I really like the simplicity of delegating responsibility and permissions to separate apks that have discretely defined scope. I'm just not sure how practical it is. If you look at the permissions that are most contentious in combination : internet and read_contacts. I have avoided several apps that appear outwardly to be perfecty ok because I could see no good reason for the app to have this combo. But internet is often required for one of these (legitimite) reasons: 1) to report use statistics (eg Flurry) 2) to request and present ads 3) to otherwise hit an external server In an apps description if (3) is required you generally get told about it. But use of (1) or (2) is typically omitted because either its an instant sale killer or the target audience won't understand. The solution that you are proposing Dianne, would be for separate apks for options (1) and (2) and to have an app be able to convince a user that it is worthwhile the hassle of downloading (and dealing with upgrades) of those apps just to let the current app run. I know that if I was presented with that, then unless the app was a real beauty I would probably bail about then. The upside is that once the lbrary apk did get installed, the next app that required it would not have the same drama. However, while any of us could create an AdServer apk in the full light of everyone else, only one person can upload it to market. That person would then have the opportunity of warping the AdServer apk to funnel whatever amount of that Ad revenue into their own account. So if we were to collaborate on such a reusable component we would need a trusted owner. This one is close to my heart, because living in Australia, unless I get a buddy in the states who is willing to collect any sale revenue for me, my only real source of income from Android is via Ad revenue or donates. At the moment, innovation in some types of apps is being stifled because a good portion of the world can't make any income from them.

How is bump's functionality as a separate .apk an unacceptable burden? It does mean the user would need to install a separate app if they want to use that functionality... but it should be very easy for the original app to explain it needs this (when they want to use the functionality), clearly associates that functionality with the bump developer (who btw gets some nice branding there), and also allows bump to upgrade their client code without having to get all of their app authors to update each app. And even if there were -- it does not solve the problem -- it just associates it with the third-party app. And that's bad, actually. It gives the user the option of not including that app, which makes things MORE complex for the user, and opens up the possibility of leading to broken situations. It also introduces the equivalent of DLL hell. Please tell me you don't want to go there! We have been avoiding standard general shared library support partly because we don't want to have DLL hell. (Also because the security implications are nasty.) However, when you implement things as separate .apks, I think this is much less an issue. If you aren't doing something extremely loosely coupled like intent protocols, I think the interaction you will have between the two pieces of code will by nature be much less tightly bound than with shared libraries. It just doesn't lend itself to a large surface area API with a lot of subtleties in interaction. It's more like client/server interaction like APIs published by Facebook and other web services. (A corollary is that this approach is not going to work for every case where you use shared libraries... but what I have been observing is that in a lot of the cases where some third party is providing a piece of functionality that is not core to the app using it, this can work quite nicely.) I really do think that optional permissions, which are requested IN THE CONTEXT OF THE NEED are very much the way to go. They are simpler for users to understand. This is how Apple does it, and while it does have its drawbacks, it is far less mysterious. I'm curious, what is this example of how Apple does it? Yes there is the location thing, which as I've said is probably an exception that should have per-app control for the user. What else? Having apps ask you to enter your password to log in as admin in MacOS X? But the current situation is not where we want to be! The current approach is I believe a strong improvement over what has gone before. Things can always be improved

Re: [android-developers] Testing several projects with a single test project
Thank you for the comment. Unfortunately it's not the case since we also want to test interaction of several applications at a time. Now we're looking at a possibility to interact between applications and testcases project via services and service connections. You can make one test package that is capable of testing several applications, but it can only test one app at a time. For each new app you want to test, you have to update AndroidManifest.xml to point to the new target app, re-build the test package, and re-install it. What is your use case? Do you have a set of unit tests that you want to apply to different apps? This is a bit unusual, but conceivable. You could do this in a shell script. First install all your apps using adb install, then use sed or awk to modify the AndroidManifest.xml in the test project, build the test package, use adb -r to install it, and then adb shell am instrument to run the test and see the results. The last command is documented in the Android 2.2 Developer's Guide, under Guide Developing Testing Testing in Other IDEs. The Elk.

Re: [android-developers] Re: Problem in encoding image
Pramod,
Base64 encoding has end-of-data markers.
http://en.wikipedia.org/wiki/Base64
Your code encodes each 1024-byte chunk of input image data into its own
Base64 string. Each of those has its own end markers.
Because of this, the receiving side doesn't see one piece of data
encoded with Base64, rather, it sees multiple pieces of data, which I
guess is not what it expects.
There are several ways to fix this:
1 - Write your own code to encode partial data pieces, flushing the
output at the very end. Base64 encoding is not difficult.
2 - Use a ready-made class, like this one:
http://commons.apache.org/codec/apidocs/org/apache/commons/codec/binary/Base64OutputStream.html
It's equivalent is available in Android starting with 2.2:
http://developer.android.com/reference/android/util/Base64OutputStream.html
3 - Change buffer size in your code to 1023 (a multiple of 3). This is a
hack, but probably the easiest thing to do.

[android-developers] MediaRecorder buffers 1 second of video
Hello, I'm using MediaRecorder.setOutputFile(FileDescriptor fd) over a UNIX socket, so that local code on the device can see the encoded stream in real time (for video streaming out). What I observed is that the encoder doesn't write encoded frames continuously, when they are produced, but by bursts, exactly one second apart. I tried both containers (THREE_GPP and MPEG_4) and all three available codecs (MPEG_4_SP, H263, H264), the behavior is always the same. This one-second period is notably unrelated to framerate or bitrate, so it is not flushing by size; rather, it seems to be flushing by time (possibly to mask SD card write overheads ? Bummer, I 'm not using the SD here !). Is it a known limitation ?

[android-developers] Re: onCellLocationChanged and updateNetworkNameExtension showing up in Log files. Where do these come from? and can I make them stop?
hi, As I know you get the event onCellLocationChanged when there is change in Cell Tower connectivity.. To stop this event you need to stop listing to this update. Look for listen method in Telephonymanager (URL: http://developer.android.com/reference/android/telephony/TelephonyManager.html). I am not aware of the other event.

[android-developers] Custom View orientation change
I have a custom view A which extends RelativeLayout and internally uses 3 instances of custom view B: B1, B2 and B3, which can be 'flung' left or right to move to B4, B5 and B6. I want to resize the whole view based on the orientation. I have hardcoded the size of B based on the screen width of 320 (if the view is initialized in potrait mode), or 480 (landscape mode), and then use the screen density from getDisplayMetrics() to convert them into real pixel values to draw my view. Is this is best way to do it? I was trying to use onSizeChanged to look for orientation changes, but this does not work because onMeasure() is called before onSizeChanged() and the orientation change does not show up.

Re: [android-developers] Re: Problem in encoding image
It's magic, man. Pure magic.
:)
Base 64 encoding converts every 3 bytes of input data to 4 bytes of
output data. If input data size is not a multiple of 3, output is padded
with = characters, which also means end of data.
Your original buffer size, 1024, is not a multiple of 3, so each output
chunk ended with end-of-data marker.
On the other hand, 1023 *is* a multiple of 3, so no end-of-data padding
is generated until the very end of data.

Hi, Kostya
I can't use second solutions because they are for API level8 and I am
developing this for APilevel4(1.6), But after changing byte array size
to 1023 it works perfectly fine, Thanks again Kostya I am working on
this from last 8 days and today I got the solution.
But still I don't know how it works with 1023 and not with 1024?
On Aug 30, 1:04 pm, Kostya Vasilyevkmans...@gmail.com wrote:
Pramod,
Base64 encoding has end-of-data markers.
http://en.wikipedia.org/wiki/Base64
Your code encodes each 1024-byte chunk of input image data into its own
Base64 string. Each of those has its own end markers.
Because of this, the receiving side doesn't see one piece of data
encoded with Base64, rather, it sees multiple pieces of data, which I
guess is not what it expects.
There are several ways to fix this:
1 - Write your own code to encode partial data pieces, flushing the
output at the very end. Base64 encoding is not difficult.
2 - Use a ready-made class, like this one:
http://commons.apache.org/codec/apidocs/org/apache/commons/codec/bina...
It's equivalent is available in Android starting with 2.2:
http://developer.android.com/reference/android/util/Base64OutputStrea...
3 - Change buffer size in your code to 1023 (a multiple of 3). This is a
hack, but probably the easiest thing to do.

OutofMemoryException. So I had decided use 1kb of byte array, in that
I encode 1kb of image write to a file after that again encode 1kb of

//bas.write(b);
}
out.close();
}

[android-developers] Re: App breaks for some users after they update from the Market
I don't know. Every email I've gotten and all comments in the crash reports indicate it's a consistent crash occurring 100% of the time (and in the exact same location based on the ever-growing report count for the same stack trace). Clearing the data (or uninstalling / re-installing which clears the data as well) makes the problem go away each and every time. I think what's happening then is that some kind of race condition corrupts your app data, after which the crash will occur every time. Of course, clearing the app data will ellivate the problem. But I still think that it's red herring: - It started to happen after you introduced static maps. - You admit using such maps in multiple threads - java.util.TreeMap is not thread safe. What I would do is wrap TreeMap around a java.util.Collections.syncronizedMap (not 100% about the name) and then release an updated app and see if the crashes go away. I know it makes your users the testers, but if you cannot duplicate it, there is not much to lose. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] onSingleTapConfirmed and different screen sizes
I am developing a game in which there are a couple of on-screen buttons the user can press to do different things. These work by responding to onSingleTapConfirmed, and checking if the getX and getY of the event are within the coordinates of the buttons. However, the getX and getY coordinates are different when the game is played on other screen sizes than the game was developed on. How is the best way to deal with that? Of course I could call getWidth and getHeight and do lots of if's on them, but it would be better to have a more general way of doing it. Does anyone know of such a way?

Re: [android-developers] Custom Service Permission
Hi KilicBeg,
Have you managed to figure it out? I have the same problem.
My problem simply is adding a custom permission like
android.permission.CAMERA to allow user use some custom
hardware feature. I've added one in platform.xml but failed in
checkCallingPermission(String16(android.permission.MY_PERMISSION))
when client connect to service.
So my question is
1. is it possible to add custom permission in android?
2. how to do it if it is feasible?
BTW, i know that my question may better post into android-post because it
derives from custom hardware,
but i post it here because i do not think this problem is
hardware-independent and hoping for more help.
Cheers,
- rookie

//Get the DocumentBuilder
DocumentBuilder docBuilder = factory.newDocumentBuilder();
//Using existing XML Document

//Add the attribute to the child
childElement.setAttribute(id,3);
root.appendChild(childElement);
//set up a transformer
TransformerFactory transfac = TransformerFactory.newInstance();
Transformer trans = transfac.newTransformer();
//create string from xml tree

StreamResult result = new StreamResult(sw);
DOMSource source = new DOMSource(doc);
trans.transform(source, result);
String xmlString = sw.toString();
OutputStream f0;
byte buf[] = xmlString.getBytes();
f0 = new FileOutputStream(connections.xml);

[android-developers] Re: Is there a way to request permissions from a user as you need them?
There is a fundamental problem that at the point you ask the permission, the user is wanting to accomplish some task at hand, and all you are doing is bugging them. That's not always true. My app requires around 30 permissions, which obviously is off-putting to some/many people. The average user will use functionality that requires maybe 5 permissions. If there was a way to request permissions at runtime, I could ask for the permissions *while the user is configuring the app*, not while the app is actually 'doing it's thing'. Then it's obvious to the user why that part of the functionality requires that particular permission. And it's less dangerous because if there's a bug in my program it has vastly less potential for damage.

[android-developers] App inconsistencies
Hi, I have an app that uses Runnables, GPS, Sensors, the AudioManager, MapView, Shared Preference storage; in effect ---all manner of the phone's capabilities. When I run this app on my Motorola DROID, it functions consistently --- all activities operate as expected -- all dialog popups POPUP when they are supposed to, all sounds are delivered when they are supposed etc etc etc. When a beta tester I have (with a new LG Ally) downloads and runs the App -- the results are all over the map (PUN intended ;) Most times, it just seems to die BUT without any this application has terminated unexpectedly dialog. The App will stop at various places inside my activities. Again, without any indication it has done so. And even stranger, the app will not do the things it supposed to be doing even though it IS still running. And ***worse yet***, sometimes, it seems to work fine ... Until maybe the next time it is launched (in other words, it was NOT re-Installed or anything so severe.) I am loathe to start adding all kinds of log output turning this into a bloatware science experiment (but will if forced.) Has anyone else had this kind of experience? I am developing on NETBEANS, targeting Android 2.x -- and the LG Ally meets these requirements. -- You received this message because you are subscribed to the Google Groups Android Developers group.

By having you link their code into your app, you are required to take responsibility for their permissions. Yet it is their code, you don't have control over it, so why should you? I agree in this case. But what about AdMob? Shouldn't Google do it better? However, there's another pitfall: What if AdMob/Bumb/whatever isn't installed? Some might say no matter, I can do without, but others certainly don't want to do without the ad income, or some external library is vital to functionality... Btw, AdMob is a good example for optional permissions itself. The AdMob library makes usage of ACCESS_FINE_LOCATION optional for local ads. Now, as a separate .apk, this would be mandatory, and I for one wouldn't install it (like all those apps that require it). Every ad supported app would drain my battery (GPS), not to mention privacy concerns. I also agree with niko20. I've got a simple music player that requires Identify call state... to pause during a call and internet for ads. I regulary get queries as to why my app wants to send identified callers to some hideous server, and I don't know how many just don't install it without comment. While the internet permissin in my case could be removed if there'd be a separate AdMob app, there are other players that need it for other ends, like downloading covers, streaming, etc. Also, in my experience, there are three kinds of users: 1. Permissions are technical stuff they don't understand and care about, so they just ignore it. 2. Paranoids who wouldn't install a contact manager that requires reading of their contacts. 3. Those who actually try to make sense of the required permissions. But even they can't tell whether an app really needs those permissions or will misuse them. My music player actually *could* collect the phone numbers and send them to any server... So the current permission system would only help the first two kinds of users (type 1 aren't disturbed by them, type 2 can panic of will read my contact data), while sensible people often are just confused. Is Evernote potentially evil because it wants access to my contacts and internet, or isn't it? I can't check why it wants those permissions without installing and testing it. By then, the harm could be done. A solution like Mart Murphy proposed sure would help in some cases. It's like if you allow me to do this, I can do that. But also a simple explanation option in the Market would help: Look, dear user, I need call state to pause during calls, and internet for ads.

[android-developers] Is there (or should there be), a generateId() method for dynamically generated Views?
Is there (or should there be), a generateId() method for dynamically generated Views? Take the RadioGroup example in APIDemos|App|Views. Radio buttons are added dynamically. For each button, you have to call setId(). To be notified when a radio button is selected, you register a onCheckedChange listener on RadioGroup and the callback method is oncheckedChange(RadioGroup, int checkedId). Since we are notified only the id of the checked view, shouldn't there be a way to uniquely generate the id? Say, a View.generateId() method... In the example, the ids are statically defined in ids.xml. However this limits the number of radio buttons. I have a real world example too: a Radiogroup with each choice representing a Wifi hotspot. So one cannot know in advance the number of hotspots. - Anil -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Froyo: MediaRecorder.setVideoFrameRate sets IDR ratio instead of frame rate
Hello, I'm using the H264 encoder on a Froyo HTC Desire. Parsing the generated 3GP stream allows to identify individual frames, and their timing. Now it turns out that: (1) MediaRecorder.setVideoFrameRate() doesn't affect the average frame rate, which is always close to 17fps, regardless of the asked rate from 4 to 30 fps. (2) In the logs I get contradictory messages (example for an asked rate of 15 fps): 08-30 16:07:48.198 E/VENC_ENC( 68): VENC_ERROR update_param_port_def::1651 Frame rate is for input port (refer to OMX IL spec) but also: 08-30 16:07:48.602 E/VENC_ENC( 68): ven_print_config::348 config frame_numerator=15, fps_denominator=1, bitrate=42 (3) By parsing the H264 NALU types, I do see the effect of varied MediaRecorder.setVideoFrameRate() values: they affect the IDR relative rate (~GOP size): - asked value 4: one IDR frame for 3 non-IDR frames - asked value 15: one IDR frame for 14 non-IDR frames - asked value 30: one IDR frame for 29 non-IDR frames All this smells like there is a bug while crossing all the API layers, passing one parameter for another. Of course I cannot say before Froyo, because in 2.1 the H264 encoder on the Desire was broken/missing. Any insight on this ?

[android-developers] Re: Is there a way to request permissions from a user as you need them?
I think its going to be very difficult to prevent applications without network or sms permissions from leaking any data they can obtain to the outside world by means of another application that does have those permissions. Its even possible for an application without network permissions to infrequently upload quite a bit of data via the default web browser. On install they can just send an intent to view a webpage containing something innocent like a welcome, help, or changelog web page for their app, while quietly shoving 100+ lines of whatever through extra post data for older android releases or extra header data for newer ones.

[android-developers] Open-Source Repository
Guys, I'm re-opening the JVending project, which has been inactive (publicly) for a couple of years. There has been some chatter from individuals interested in an open-source repository for Android so I think it will be a good start. You can basically think of it as an Android delivery system where you can filter and deliver content based on type of device. For example filtering out Android 2.1+ content for Android 1.5 devices. Things like matching rules and device profiles are configured through configurations files. You can plugin specialized delivery adapters if you have specialized content to deliver to the Android device. It also handles localization, versioning of apps, variations, etc. JVending is the building block for a larger system so this project is really for developers who can dive in and customize the front-end and/or back-end services that they need. If you want to donate some front-end web functionality (or anything else), I'll add it to the core project. I'll also be hosting a dev version for people to try out the latest build changes. I can also see putting up a production server for open-source android apps at some point. Some changes in the project: 1) Moving the license from LGPL to ASL2. 2) I've refactored the code collapsing a number of modules 3) Significant performance optimizations in Hibernate 4) Android Events Database In the upcoming commit, I'm also hemorrhaging a number of archaic aspects of JVending like the provisioning archive and stocking api, which made sense 8 years ago but with the size of applications growing significantly (a 300KB application at that time was considered huge, most were 50-60KB), these things don't make sense. So I'll be moving away from the JSR-124 spec toward something more appropriate to today's mobile environment. I still need to add a module for the webservice itself, which will be out shortly, but feel free to dive in. http://github.com/sisbell/jvending I've also opened up the* jam *project (JVending Application Manager), which will be an open-source download and discovery manager. A lot of people have been interested in this part of the project. http://github.com/sisbell/jam I'm not putting any code out there yet till things like the feeds go up in the webservice. Once the community decides what the feeds to the mobile client should look like, we can build out the client. For SlideME, I had a simple, custom format for the feeds, but am thinking to use JSON or something similar to standardize it. Feel free to open any issues on github, submit patches, follow, make comments, etc. After a few good patches, I usually offer people to become a committer on the project. -- Shane Isbell (Founder of ZappMarket) http://apps.facebook.com/zappmarket/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: App inconsistencies
A good log app is called (strangely enough) Sendlog - it's fairly lightweight and just asks the user to enter an e-mail address. Select detailed logs for the best result. As for adding logging statements all over the place. That's a very good idea with one caveat. Add a logging variable like this to the top of your source: static final boolean DOLOG = false ; Then preface all your logging statements with a test: if ( DOLOG ) Log.v(Foo,Logging message) ; When you create your beta, set DOLOG = true. That will include the logging messages. When you create your production version, set it to false. The compiler will exclude all those logging statements because they will never execute. The compiler is smart enough to know this, so your production code will be streamlined without physically removing (yourself) the logging statements from the code. I believe this is the preferred method of coding your logging statements. -John Coryat -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: App breaks for some users after they update from the Market
On Sun, Aug 29, 2010 at 8:24 PM, William Ferguson william.ferguson.au@ gmail.com wrote: What's the taskAffinity? Whatever the default is - I've never touched this. I suspect that clearing the data is changing the behaviour because this speed up / slows down one of the threads, thereby (generally) avoiding the race condition. I have a feature that auto-backs up all user data to the SD and restores it if the local data file is gone. So even if they clear the local data, it's restored on the next app start up. So regardless, all user saved data is there before and after they clear the app's local data storage to alleviate the problem. And the crash does not occur in the first activity, where data is usually loaded. I say usually because it's lazy-loaded (so if the user navigates away from the second activity and comes back much later, it's possible the memory got wiped). But this occurs in onCreate in the main thread of the second activity, and this activity does not try to do anything with the user data until after the point at which the crash occurs. I'd be tempted to 1) synchronize the method Probably a good idea, I'll be doing that =) 2) make the static instance an instance of your Application class. I started using a custom Application class a while ago and quickly got tired of having to cast up each time I needed to do something with it. I'll try a better implementation of a Singleton first.

But the main activity that starts up and loads the user data each and every time does not crash, and the point at which the crash happens is NOT using user data - it's using a hard-coded reference which is explicitly set in code. That reference, somehow, ends up being null, even though previously it was (probably) used in the user-data loading process. WTF!? - It started to happen after you introduced static maps. Weird stuff after updating like this has happened before, though this time it's much more widespread and consistent. Also, note that the map itself is not static: there is a static instance of the class that contains a map. Don't know if that makes a huge difference, but it's worth pointing out. - You admit using such maps in multiple threads - java.util.TreeMap is not thread safe. Yes, but the map is initialized ONCE in the main thread and never altered again. I'm not adding or removing anything from it at any other point. It's there strictly to get access to the pre-defined derived-type instances I need to use depending on the user's selection. Also, no thread is started until after this map is initialized. What I would do is wrap TreeMap around a java.util.Collections.syncronizedMap (not 100% about the name) and then release an updated app and see if the crashes go away. I know it makes your users the testers, but if you cannot duplicate it, there is not much to lose. Indeed, anything is worth a shot at this point! I'll try that when I get a chance and post back what I see. IF YOU'RE REALLY BORED and want more context to the problem, you can check out the free version of my app. From the main screen use the menu and select Trek Tracker to open the second activity where the crash occurs. This screen is series of drop downs for the user to drill down to the stop they want bus predictions for. The first option is the transit system - these are the hard-coded values in the map: the strings the user sees are the keys, pulled directly from the map, and they point to the derived type which handles the logic for getting data for that system. All of these options are loaded in onCreate and pulled directly from the map - if this part is working, that map should be completely valid at this point. Next the user selects a route, direction, and stop, each populated dynamically based on the previous selection. Once the stop is selected, that's all the data I need to get bus arrival predictions, so at this point a thread is spawned with the users's selected data to load the predictions every minute or so. This is where the crash occurs. The background thread tries to use the reference to the transit system it got from the very first selection, which I swear should be valid at this point, and throws a NullPointerException. So somehow, that reference which is EXPLICITLY set with map.put(Key, new Derived()), ends up being null and then only in this activity. Thanks for the continued help folks.

Re: [android-developers] Re: App inconsistencies
Yes, Logcat appears to run independently of adb or your local debugging connection, and has logcat output from *all* applications that use Android log.* methods and the Android system itself. Note that if you start logcat from the console of your development machine (adb logcat) it first scrolls, displaying the information that has already been accumulated before you typed the command. I suggest starting with one of those apps, since it would be just so easy for you and your user to take first step. +1 to what John Coryat is saying. I actually do this in my app, have my own logging facility, controlled by a simple boolean static variable. This way it's easy to make a custom build for those users who are having problems. -- Kostya 30.08.2010 17:48, tony obrien пишет: I am familiar with using LOGCAT via my local TERMINAL Session..

I've seen a few other similar threads, but none that both matched my
problem and had answers, so sorry if this retreads familiar ground.
I've got a browser and I'm trying to catch the same intents as the
google browser. I've even gone so far as to copy and paste them
directly from Froyo's browser. They are listed down below for
reference. However, when I try to send an intent to create the chooser
so the user can select my browser as the default it does not always
appear. Here is the code for creating the intent:
Intent anIntent = new Intent(android.intent.action.VIEW, http://
www.google.com);
anIntent.addCategory(Intent.CATEGORY_BROWSABLE);
startActivity(anIntent);
and the logcat output:
08-26 14:53:25.698: INFO/ActivityManager(85): Starting activity:
Intent { act=android.intent.action.VIEW
cat=[android.intent.category.BROWSABLE] dat=http://www.google.com
cmp=com.android.browser/.BrowserActivity }
For some reason the intent is automatically resolving to Google's
browser unless one of the following is true:
1) I've cleared the defaults from the google browser via application
settings,
2) I've installed a third browser, or even just a HelloWorld app with
the intent-filters listed below, or
3) I'm running on a platform earlier than 2.2
What is really confusing is #2. It doesn't matter what that third app
is. I've used a default hello world with just the first intent-filter
and that's enough to trigger something behind the scenes that tells
Google it's no longer the only default browser. However, it's not
enough in my own app, and the only differences in the two manifests
are that mine has a sharedUserId, a couple of extra activities (none
of which have intent-filters) and permissions (none of which have
anything to do with browsing, in fact HelloWorld doesn't have any
permissions at all).
The program flow is: user opens browser, it sees that it's not fully
installed and opens another activity, that activity does some stuff
(none of which deals with intents) and then checks to see if my
browser is the default, if not it fires off the aforementioned intent
to create the chooser so the user can set the default.
Is there a change in froyo that would cause an application to not be
able to use startActivity with a generic intent that matches to its
own package? Or some other change to the way activities are resolved
or installed that broke the way preferred activities are defined? I
know that the PackageManager preferred activity functions have
changed, but I'm not using them at all.

[android-developers] Google TV Developers
Hey guys, I'm sure some of you have heard about Google TV - I myself am excited about the possibilities for Android apps in the living room. Being a developer myself, I tried to find a community centered around Google TV development and couldn't find one, so I started one. The site just launched, but I think when the SDK is released, Android market is opened, and the market for smart TVs grow, the developer community will grow with it. Please join us at http://www.gtvconnection.com for Google TV specific development. - Chris -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Sending SMS while phone is ringing
Hi, I'm developing an application for Android 2.2 that should send an SMS immediately when the phone starts ringing (under UMTS/GSM). I'm using the android.telephony.SmsManager.sendTextMessage for sending the SMS. The app is working fine under the emulator, i.e. when I call the emulator phone from another emulator, the SMS is sent instantly. However, when I'm testing the application on HTC Desire, the SMS sending only succeeds after the phone has stopped ringing. Is there anything that could be done about this or is it just a restriction of the HTC Desire device? Seems strange as it's working fine under emulator and it shouldn't be a restriction of the network.. -- You received this message because you are subscribed to the Google Groups Android Developers group.
