[android-developers] Re: TabHost and New Activities
Activities inside TabAcitivity are not true acitivities, and so have some limitations that I noticed. And of course, no documentation about that: * you can't bind to a service, onServiceConnected will never be called. * window features (only available in the TabActivity). * you can't use most of the manifest properties such as the launch flags, and so you can not send intents to an activity inside a tab even in singleTop launch mode, a new activity in full screen will be launched if you try. There must be some other limitations, I don't tested all. What I tried and is working: * Life cycle methods * Menu methods (call super each time when overriding panel menu methods if you want to mix menu items with TabActivity). * startActivity methods.

[android-developers] Keeping a Service Alive
Hey all, I'm really hoping someone can help me out on this one cause I'm starting to pull my hair out... I've got a service binding to my main activity. The service is running a media player that is playing music in the background. The service also places a notification in the status bar and connects to a local database to receive track name and url info. I'm having two slightly different problems keeping my service alive. 1) When my main activity is destroyed, my service is getting destroyed along with it. The service's onDestroy get's called, playback stops, the notification gets cleared. How can I avoid this? By playing around with the unbindService(ServiceConnection) method in my activity, I've realized that it is what causes the service to be destroyed. So how can I unbind a service without destroying said service? (I'm also having a similar problem with Alarms set with AlarmManager getting destroyed with the destruction of my activity, but unless you recognize this issue right away, I'll save it for another thread.) 2) When my activity doesn't get destroyed right away (i.e. i exit via the home button instead of the back button) and I start doing other things on the device (or emulator) to take up resources, eventually the music will stop playing, but the icon in the status bar will not change, meaning the service's onDestroy is not even getting called (onDestroy clears the notif icon). I think this means that the service was killed to free memory but how can I react to that or prevent it or increase the importance of the service? I've put the imeem application through the same kind of tests and it does not stop playing even when the phone gets low on resources (however I don't know if they're using the built in MediaPlayer, but I'd assume so). So... any ideas? I think #1 is more important but I also think the 2 issues might be connected.

[android-developers] native audio interface / AudioRecord.h
David, Thank you very very much for the tips. I've gotten as far as downloading the android source code (onto a clean ubuntu VM I built for the job) and doing an initial make (which generated quite a lot of whining level errors but seemed to complete ok). I'm so-so at Java but a pretty old hand at C/C++ so hopefully I will be able to work through the remaining steps. Can you recommend any other similar interface classes I could examine for general clues? Once I get all this done, will the .so in the .apk be able to go through the marketplace and run on a real G1 or will I only be able to play with in on the emulator? In any case, I will write progress reports to the list and make the code available to all if I succeed.

[android-developers] Re: Keeping a Service Alive
EUREKA! I've figured it out based on some of the documentation I missed. For those who also have trouble... The docs for ContextWrapper.startService(Intent service) includes the following line... Using startService() overrides the default service lifetime that is managed by bindService(Intent, ServiceConnection, int): it requires the service to remain running until stopService(Intent) is called, regardless of whether any clients are connected to it. This is the trick, simply run startService() before you attempt to bind to it! So before, my onCreate contained: bindService(new Intent(MDService.class.getName()), mConnection, Context.BIND_AUTO_CREATE); Now this has been replaced by: Intent i = new Intent(MDService.class.getName()); startService(i); bindService(i, mConnection, Context.BIND_AUTO_CREATE); After that change, calling unbindService(mConnection) does NOT destroy the service :) So starting a service by binding it from an activity links the service's life-cycle with that of the activity. While starting the Service first, gives it it's own lifecycle, and you can still bind to it right after. (And you still know the service will only actually be started once.) Also, doing this seems to have alleviated my 2nd problem that I described in my 1st post, but this requires a little more testing before i can confirm it. On Nov 23, 3:09 pm, G [EMAIL PROTECTED] wrote: I just realized that the in API Demo for Remote Service Binding, the service is destroyed when the activity is destroyed as well.

The examples that Guillaume points you to cover most of what you want

What they don't cover is multipart mime messages and setting mime

[android-developers] Re: Keeping a Service Alive
Please please please be sure to stop the service when it is no longer needed. For a media player, this generally means only having it in the running state when it is actively playing music; otherwise it should only be needed when there are clients bound to it. If you don't stop your services, then the system has to assume it is needed forever and can't remove your process to allow for other things the user is actually doing. I think this is actually one of our biggest third party application issues, applications that just starts a service and never stops it. This sucks for the user, and just should not be done. In fact there is already code in the system to look for services that have been running a long time without others doing things to them to let them be killed, but it's pretty clear we'll need to be even more brutal about this. :( (Which sucks for things that really do want to run for a long time, like a media player, but it's not clear at all to me what to do about them.) Also, there was a suggestion earlier to try running the service in another process. Multiple processes is again something to be careful of, and to stay away from unless you really need them -- processes are quite heavy-weight entities, so shouldn't be thrown around lightly.

[android-developers] Hooks in Activity life cycle
Hi, I'm trying to create an app that needs to do this: a) Hold the PARTIAL_WAKE_LOCK in the started mode so that it continues to work even if the screen goes off (it is a sound-based application) b) May or may not turn off the sound when the home key is pressed. Either way is fine with me. c) Turns off the sound when the back key is pressed. The problem that I am running into is that I can satisfy c) by turning off the sound and releasing the PARTIAL_WAKE_LOCK in either onPause() or onStop(). However, onPause() is also called when the screen shuts off, so I cannot satisfy c). Is there some combination of hooks to write so that I can distinguish between the back key and the screen turning off?

//countText.setText(mi.title);
items[i] = new TextView(this);
items[i].setClickable(true);
items[i].setText(mi.title);
inteIntent = new Intent(this, MIScreen.class);
inteIntent.putExtra(com.android.MIScreen.curIndex, i);
items[i].setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
startActivity(inteIntent);
}
});
linearLayout.addView(items[i]);
//items[i].setVisibility(1);
};
What happens is every button I click just has the last intent settings
so no matter which one I click the next screen shows that I clicked
the last item. I also tried to do this by using an array of intents.
But that gives me an error when I click a button that I have not been
able to figure out.
So how should I be doing this? Am I taking the wrong approach
completely or am I just missing something small?
Also, Im trying to use the wsimport tool to set up the Amazon API but
am very unfamiliar with the Java tools and can't get wsimport to run
on the command line at all.
Thanks.

[android-developers] adb device detection of G1 on Linux
The Android documentation has been updated with some notes on Developing on Android Hardware at http://code.google.com/android/intro/develop-and-debug.html#developingondevicehardware. I had some struggles with this as I followed the instructions and verified the device was listed in the lsusb output. Even with lsusb showing the device adb devices failed to detect it. I had been running adb against an emulator before adding /etc/udev/rules.d/50- android.rules. After some trial and error I ran adb kill-server. The next time I ran adb devices it started a new server and the device appeared as it should. So if anyone is having problems with detection of the G1 you might try restarting the adb server after messing with the udev rules. My experiment was with Debian Unstable. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: how to inject a KeyEvent
I'm just wondering about these security issues, injecting events, access to some low level APIs, screen lock, telephony, etc. I've been developing on other mobile operating systems for years and all them allow this kind of technique, it's valuable for some kind of applications, mainly in corporate applications where the company wants the user with no access to phone features like downloads, games, etc, but only a limited set of features. My question is, would you consider adding all this 'privileged' APIs to the security in the manifest, with a 'red' level of alert to the user upon installation, with description of the potential risks, so that user can decide? I know Android core developers said they don't want user to decide, but in my oppinion it is really what should happen. Just my thought.

[android-developers] How can I send CJK text via SMS on G1
Hello developpers. I am suffering sending CJK(Chinese, Japanese, Korean) text using SMS. I copypaseted following code in my code. SmsManager sms=SmsManager.getDefault(); sms.sendTextMessage(x, null, 한글test, null, null); It works when I send english text only. But when I send CJK text, it returned empty text. Above code gave me, test only. I have tested two G1 phone, mine and my wife's. I saw aPowerSms can send Chinese text SMS, how can I do the same thing for Korean. Any response would be appreciated.

[android-developers] Re: missing javax audio?
Greets... I am an audio/graphics professional and my first project, for kicks, is to port my desktop Java Quake3 class game engine to Android and OpenGL ES as a test of well my ability to figure out ES and Android and it didn't take long to realize the state of audio in SDK 1.0 is not suitable for lots of audio stuff I'd like to accomplish in general and some novel features for my port (IE voice chat with desktop clients from built in mic on G1, etc; fun!). We'll see how the Q3 port turns out; gonna hack a file based push to talk feature most likely via MediaRecorder; delayed audio w/ this though and only one way to desktop clients to show proof of concept. I specifically did not adopt or even look at Android until a handset device was released and the SDK hit 1.0 simply because I knew the platform probably would not be complete and I don't have the time / desire to work around incomplete APIs / implementation (yes, was correct on that; for audio at least; lots of gold to be had elsewhere; seriously, kudos Android team et al, I haven't been this excited in a while!). So, yes, lets continue to discuss how to solve the audio issue that encroaches on all of us who want performance audio on Android and all 'droid devices in general. I will throw in my two cents on how I _am_ (not would be) solving it after dealing with the woes and inadequacies of Java Sound on the desktop _for years_ from an API perspective to simply incomplete implementations on various platforms and JVM versions. (Java Sound - Write once, test everywhe... oh wait you mean it doesn't fully work on X platform at all?.?. gah!!!) One solution on the desktop has been to ditch Java Sound and support PortAudio (www.portaudio.com) via JNI. I propose that Android can also provide the best and most _portable_ audio solution not only on the G1 and other devices, but _future_ hardware that supports Android by adopting PortAudio and exposing a lean and mean API to developers that then can be further extended with higher level APIs for purpose built processes (speech detection / Jspeex port / DSP processing, even a javax.sound implementation built _on top_ of PortAudio, etc). What is needed is simple and efficient raw audio I/O functionality at the core; PortAudio provides this and only this! For file I/O it's not a bad idea to support Libsndfile (http://www.mega-nerd.com/libsndfile/). Between PortAudio Libsndfile raw streaming and file based audio I/O can be solved by time tested open source solutions. Now... I mentioned future hardware supporting Android... I just so happen to be developing an embedded audio hardware product that focuses on advanced spatial processing (think large scale 2D and 3D sound arrays; I have a 32 speaker hemisphere setup at my facility in SF for instance; check here for those interested in an overview I published for the recent AES conference in SF w/ picts equipment specifications -- http://research.egrsoftware.com/conferences/2008/aes2008/) and after finally dipping into Android (IE G1 SDK 1.0 finally available) I've decided unanimously and almost instantly to ditch my current path which was Analog Devices Blackfin/Sharc based processors running uClinux and am switching to the TI OMAP3 3550 and Android as the processor/stack. In doing this I already am adopting PortAudio on my Android based hardware and this is how I plan to expose audio I/O to Android developers on my hardware. So in time this is _going_ to be done already. Seeing as there isn't a unified vision on where to take audio I/O for Android as is I do strongly propose supporting PortAudio out of it's shear elegance and wide activity and support in the audio community at large across numerous OSes / desktop to mobile. Not only will it provide a mean and lean audio API at the core, but it will be portable at its core between different hardware configurations on hand sets to say custom built audio hardware like my own efforts which will support high channel count analog, ADAT, and even MADI I/O. There is absolutely no reason to support Java Sound as the core implementation just because that is the most visible Java API for audio to the layman programmer; that would be archaic and quite honestly just silly. Audio professionals and people serious with audio and Java _likely_ concur. Anyway... Since I'm already planning PortAudio support with my own 'droid based hardware and it's _very_ applicable to Android as a whole for the entire developer community across all devices and isn't based on a trade marked open or proprietary company oriented API / implementation (SoniVox, sorry!), but a tried and true open source solution that is known to work for many widely adopted cross platform audio applications to great ASIO and device specific hardware it is a compelling way forward. I'll even go so far as offering to get on that black bus for a month or two and simply knock PortAudio support out quickly and efficiently for all... Hey.. I love open source, but that

Guys, does anyone have G1? We published application (http:// andappstore.com/AndroidPhoneApplications/apps/3108), but it seems to be crashing on G1. It works fine on emulator. Could you load it on your phone and try to run. The feedback from users is not good. They only say thet app keeps on crashing. We need to know at least when it crashes: on start, during menu navigation or during gameplay (app is game). P.S. We could not test this by our own, because of our team location: Russia.

[android-developers] Back doesn't work when WebView has launched the real browser
Hi, the code is really simple, just the standard launch of a local
webpage in the asset folder:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl(file:///android_asset/index.html);
}
For this test index.html just contains a link to an external site.
What I find is that the app shows this page in the WebView ok, the
user can select the link, and they are taken off to that site in the
real onboard android browser. But I want them to be able to press
the back button then and be taken back to my app - they are not, the
real browser just shuts down and they are left at the home screen.
When this happens on a G1 I find I can then long press the home button
and switch to my app as it was still running all along. I need this to
be automatic - what have I missed please?

[android-developers] Theme setting for all applications
Hello, I would like to ask you about how to change application theme. In case of application-specific theme, it is possible to change theme by asking your Activity to call setTheme(int theme). On the other hand, how can we change theme applicable to all applications which does not have their own theme? As you know, Windows OS has a theme setting which can be changed by an end-user in the display property of control panel. Does android platform support this feature? If Android platform does not support theme setting, I have the following solutions from developer point of view. (1) Modify themes.xml provided by Android framework as default, and then make a build. (/frameworks/base/core/res/res/values/themes.xml) (2) Change Android open source code to add new APIs for changing theme for all applications. Is there any other better solution to change theme for all applications?

Here's what I'm currently using: XML: TabHost xmlns:android=http://schemas.android.com/apk/res/android; android:id=@android:id/tabhost android:layout_width=fill_parent android:layout_height=fill_parent TabWidget android:id=@android:id/tabs android:layout_width=fill_parent android:layout_height=fill_parent/ FrameLayout android:id=@android:id/tabcontent android:layout_width=fill_parent android:layout_height=fill_parent android:paddingTop=65px /FrameLayout /TabHost Java: setContentView(R.layout.test); TabHost tabHost = getTabHost(); TabSpec tab = tabHost.newTabSpec(Main); tab.setContent(new Intent(this, Main.class)); tab.setIndicator(Main); tabHost.addTab(tab); Thanks in advance! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Hmmm... I've seen apps that use tabs significantly smaller than that of the default ones. I believe that they can be modified.

[android-developers] Re: Keeping a Service Alive
Don't worry, apps that leave services running is a pet peeve of mine too. Making sure my service stops when it's supposed to is a priority of mine. On Nov 23, 7:47 pm, Dianne Hackborn [EMAIL PROTECTED] wrote: Please please please be sure to stop the service when it is no longer needed. For a media player, this generally means only having it in the running state when it is actively playing music; otherwise it should only be needed when there are clients bound to it. If you don't stop your services, then the system has to assume it is needed forever and can't remove your process to allow for other things the user is actually doing. I think this is actually one of our biggest third party application issues, applications that just starts a service and never stops it. This sucks for the user, and just should not be done. In fact there is already code in the system to look for services that have been running a long time without others doing things to them to let them be killed, but it's pretty clear we'll need to be even more brutal about this. :( (Which sucks for things that really do want to run for a long time, like a media player, but it's not clear at all to me what to do about them.) Also, there was a suggestion earlier to try running the service in another process. Multiple processes is again something to be careful of, and to stay away from unless you really need them -- processes are quite heavy-weight entities, so shouldn't be thrown around lightly. On Sun, Nov 23, 2008 at 12:42 PM, G [EMAIL PROTECTED] wrote: EUREKA! I've figured it out based on some of the documentation I missed. For those who also have trouble... The docs for ContextWrapper.startService(Intent service) includes the following line... Using startService() overrides the default service lifetime that is managed by bindService(Intent, ServiceConnection, int): it requires the service to remain running until stopService(Intent) is called, regardless of whether any clients are connected to it. This is the trick, simply run startService() before you attempt to bind to it! So before, my onCreate contained: bindService(new Intent(MDService.class.getName()), mConnection, Context.BIND_AUTO_CREATE); Now this has been replaced by: Intent i = new Intent(MDService.class.getName()); startService(i); bindService(i, mConnection, Context.BIND_AUTO_CREATE); After that change, calling unbindService(mConnection) does NOT destroy the service :) So starting a service by binding it from an activity links the service's life-cycle with that of the activity. While starting the Service first, gives it it's own lifecycle, and you can still bind to it right after. (And you still know the service will only actually be started once.) Also, doing this seems to have alleviated my 2nd problem that I described in my 1st post, but this requires a little more testing before i can confirm it. On Nov 23, 3:09 pm, G [EMAIL PROTECTED] wrote: I just realized that the in API Demo for Remote Service Binding, the service is destroyed when the activity is destroyed as well. So it's no help in this case. Can anyone point to a code sample in which a service outlives it's binding in an activity? Do I need to use a BroadcastReceiver or something? I'm very confused :( On Nov 23, 2:46 pm, G [EMAIL PROTECTED] wrote: That is what I've been trying to do, below is the service definition in my AndroidManifest.xml file service android:name=.MDService android:process=:remote intent-filter action android:name=com.episode6.android.carolla.MDService/ action /intent-filter /service And I bind the service in my activity with the following call... bindService(new Intent(MDService.class.getName()), mConnection, Context.BIND_AUTO_CREATE); And whenever I run unbindService(mConnection); the service still gets destroyed.

I think that is my best bet. Thanks loty On Nov 21, 5:02 pm, loty [EMAIL PROTECTED] wrote: Ok, I guess I misunderstood. Well you can use Timer object to initiate your flips instead of doing setFlipInterval and startFlipping. This way you can do whatever you want before and after each flip. On Nov 21, 7:40 am, Ngewi [EMAIL PROTECTED] wrote: Yes,ViewFlippercan flip on its own. When you call setFlipInterval (int timeInMs) and then call startFlipping() the flipper will switch the views every timeInMs millisecs. I can handle the flips that I trigger manually, but I want to also handle them when they are automatic. There is the possibility of using a Timer object and scheduling a TimerTask to run every timeInMs, but this does not provide accuracy. i.e. I do not have a guarantee that the timing is synchronized, so I cannot achieve the goal of performing an action just before showing the next view. I was just wondering if there is a better way to do this. Thanks for your response. On Nov 20, 7:30 pm,loty[EMAIL PROTECTED] wrote: I don't understand it - you tellViewFlipperto flip views, it doesn't flip anything on it's own.

Is there a way to get notified or register a listener to be called each time just before a new child view is displayed. (i.e with automatic flipping ). So far I have not seen any listeners in the documentation for this purpose. I would also like to use this to check, each time a view is loaded, if it is the last and return to the calling activity instead wrapping around to start from the beginning of theViewFlipperchild views.
