[android-developers] Re: Tut (SDK 1.5) Get google account of user
I have been investigating whether GoogleLoginService can substitute for ClientLogin (see http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html) on Google App Engine. To use ClientLogin, I solicit the username and password from the user in a dialog and exchange them on the Google server (https:// www.google.com/accounts/ClientLogin) for a 203-character string called "Auth". This "Auth" string can then be exchanged for a cookie on the application server (http://myapp.appspot.com/_ah/login?auth=...). The "Value" of this obtained cookie is a 460-character string. The cookie can be used from then on to maintain the user session. I was able to obtain the "authtoken", aka "SID", using the GoogleLoginService method described in this thread. The "authtoken" obtained through this method also happened to be 203 characters. I was hoping that the "authtoken" might be substituted for the "Auth" string in the ClientLogin process, thus bypassing the need to solicit the username/password. Sadly, this appears not to be the case. ClientLogin returns a "500" Server Error rather than the "204" I usually get with a good login. So unless anyone out there is aware to the contrary, my conclusion is that you must prompt the user for their password if you want an authenticated App Engine session. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Multiple data for an intent
Any application you are going to send multiple pieces of data to would need to be written to explicitly support it -- it's not like maps is magically going to do anything sane with multiple geo URIs even if there was a way to get them to it. Intent supports one data field. I doubt this will change. In Eclair I believe there will be a new intent protocol for sharing multiple data items, but it puts that data in the bundle, and applications must explicitly support it.

[android-developers] Native code is being called successfully but not executed properly
hai folks,
In Android , Native code is written as follows.
JNIEXPORT void JNICALL Java_com_android_Test_show(JNIEnv *env, jobject
obj)
{
printf("THIS IS TEST");
}
JNIEXPORT jint JNI_OnLoad(JavaVM *vm, void *reserved)
{
JNIEnv *env;
JNINativeMethod meth;
jclass k;
jint r;
r = (*vm)->GetEnv (vm, (void **) &env, JNI_VERSION_1_4);
k = (*env)->FindClass (env, "com.android.Test.show");
meth.name = "show";
meth.signature = "()V";
meth.fnPtr = Java_com.android.Test.show;
r = (*env)->RegisterNatives (env, k, &meth, 1);
return JNI_VERSION_1_4;
}
JNIEXPORT void JNI_OnUnload(JavaVM *vm, void *reserved)
{
JNIEnv *env;
jclass k;
jint r;
r = (*vm)->GetEnv (vm, (void **) &env, JNI_VERSION_1_4);
k = (*env)->FindClass (env, "com.android.Test.show");
(*env)->UnregisterNatives(env, k);
}
While executing on Android the following messages are obeserved in adb
logcat.
JNI ( 524): Trying to load jni .so
I/System.out( 524): /system/lib
D/dalvikvm( 524): Trying to load lib /data/libjnilibs.so 0x433f22d0
D/dalvikvm( 524): Added shared lib /data/libjnilibs.so 0x433f22d0
I/ActivityManager( 50): Displayed activity
com.android.helloactivity
But "THIS IS TEST" is not being displayed, which is displayed in
native code.
There are no errors regarding loading shared library and calling
native code.Then why is the message is not displayed in logging.
Am i doing any mistake.If JNI_OnLoad and JNI_OnUnLoad are not
implemented i am getting errors in Logging.If i do as above i not
getting that native code message.
Any help would be appreciated highly.

-Siva.

[android-developers] Re: how do real-time monitor the state of SD card
my quetion is from switching "usb connected" in the phone

also, use broadcast receivers,the code like this, but it's still not

[android-developers] Re: Play audio over an active phone call, so other end can hear it
You can't do this on the G1 class hardware. This audio routing is handled by the baseband, which is a separate CPU running the radio and other related things.

[android-developers] Re: screen size of emulator?
You generally don't, your views get told the size they should be as part of
the view hierarchy layout. Directly getting the size of the display is not
recommended, because it may have no relation to the actual space your UI has
available (such as if there are other screen decorations around, like a task
switcher or who knows what).

[android-developers] Re: Microphone signal ..source
What you are asking for is a non-trivial problem. To determine the frequency of a signal you have to capture a number of samples. Whether they go to a memory buffer or SD is a detail. You then need to perform a Fast Fourier Transform (or similar transform for the pedantic ones) to determine the frequency. The more samples you collect the more accurate the result. You need more samples to (1) make a more fine grade determination of the frequency and (2) to increase the signal to noise ratio.

[android-developers] Re: How can I start the ADB Deamon programatically ???
I believe that the deamon service can be communicate with other application through TCP/IP protocol (localhost:5039). I just don't know how to start it. The ADB server run on the development machine can do this. It can send some commands to deamon service to start the deamon and retrieve data from that. I don't care if the SDK supports this, but I think there is a same way to start it.

[android-developers] Setting empty text on listView that does not have @+android:list as its ID?
I've got a tabhost that has a number of tabs that all contain a ListView (among other widgets). I need to address each ListView separately and so they all have a unique ID that is not @+android:list. How does one define the empty text for a list if the only way that it can be done is through the assumption that the list will have an id of @+id/android:list and the empty text @+id/android:empty Thanks Lee --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: How i can create usable android project's library
Oops, I'll have to retract that; my test was invalid. The manifest lines I added were incorrect (forgot the tags), causing my new version not to be installed... I do indeed find problems in my log now, such as: 09-09 19:28:11.484: WARN/ResourceType(580): No package identifier when getting value for resource number 0x7f06 -and- 09-09 19:29:18.184: ERROR/AndroidRuntime(3002): Caused by: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list' followed by F/C. Sorry for the mix-up! I was also misled by the fact that I could reference the ID's of the resources inside the JAR, suggested by Eclipse's autocomplete behavior. I think the best way to accomplish what I was intending will be to install an entirely separate .apk with the libraries.

[android-developers] Re: Deep sleep behaviour
Thanks Mark, that is a great explanation. Another way one can look at this: your app is probably not nearly that important to most of your users. We are increasingly working on ways to let the users know which apps are doing this kind of stuff, so they can make good decisions about the things running on their device, and uninstall such apps if they don't find them important enough.

Here are my files: > testSpinner.setBackgroundColor(Color.BLUE); Get rid of this line, and I suspect your drop-down button will appear. Most interactive widgets in Android use the background for part of the interactivity. In the case of Spinner, I think the drop-down button is part of the background of the widget. By replacing the standard background with a solid blue background, you inadvertently "take out" the drop-down button. You'll run into this problem as well if you try replacing the background of any widget that is focusable (e.g., Button), as the orange focus ring is part of the widget background. If you truly wish to customize the widget background, you can do so, but you will need to jump through a fair number of hoops. FWIW, I just made a note to cover some of that process in the next update to my Advanced Android book. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android 1.5 Programming Books: http://commonsware.com/books.html --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

you click on it, it works properly and you can choose from the items.
I have looked through Internet resources and three books but cannot
seem to find an answer to this. Here are my files:

Thanks for that I think the problem was far simpler, I was coding late
at night and I didn't set the class to implement SensorEventListener

[android-developers] Re: Deep sleep behaviour
Lee wrote: > Following that philosophy to the end, the user should never turn the > device on. How much power cost is depends greatly upon what one is doing. An every-5-seconds service is pretty likely to be very bad for battery life. I really encourage everyone to watch Jeff Sharkey's Google I/O 2009 presentation: http://code.google.com/events/io/sessions/CodingLifeBatteryLife.html Quoting from the key slide for this case: "* Waking up in the background when the phone would otherwise be sleeping * App wakes up every 10 minutes to update * Takes about 8 seconds to update, 350mA * Cost during a given hour: * 3600 seconds * 5mA = 5mAh resting * 6 times * 8 sec * 350 mA = 4.6mAh updating" Now, his case was for an app that was updating data over the Internet, which is why his power usage was 350mA for that period. In the case of an every-5-second service, I will make two assumptions: 1. Battery usage will be around 20mA, mid-way between totally idle and typical usage. 2. That it will effectively continuously draw that power, as a combination of its own code and other system-level things that go on as a result of its code, and the fact that the CPU might effectively stay awake during the whole time handling all of that. That means that, during an hour, it'll draw 20mAh, versus 5mAh for normal idle. So, let's take a user that seriously uses the device for only about an hour a day (350mA), etc. With a G1, that should result in slightly over two days runtime between charges (2 hours usage @ 350mA, 46 hours idle @ 5mA = 930mAh compared to 1150mAh capacity). The every-5-seconds app will cut that back to slightly over one day (1 hour usage @ 350mAh, 23 hours idle @ 20mAh = 810mAh). In other words, *one app* roughly halves the battery life of the G1. Obviously, actual real-world testing would have to be done, because my estimates may be high or low, as I know neither the code being executed every 5 seconds nor the specific details on if the device will actually fall back asleep much in between the 5-second intervals. However, this effect, I suspect, is why Ms. Hackborn asked that developers not do this. Now, if you are developing code to go in firmware on some set-top box, or something else that has a continuous source of power, then this issue falls away. But for a mobile device, something that effectively runs all the time is a bad idea. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Development Wiki: http://wiki.andmob.org --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Animation of a View
I understand that animating a View using startAnimation() with a TranslateAnimation object really just applies a transform on the canvas that is being drawn on. In my case, the problems with this are: a) sometimes I need to call bringChildToFront() (for a different View) on the ViewGroup during the animation, which messes up the animation because it triggers a requestLayout on all children, which in turn re- lays out the child being animated... which messes up the continuity of the animation. Perhaps causing a layout on the child being animated isn't supposed to mess up animations, but it seems to be in my case. b) after the animation (using an AnimationListener), I need to re- layout the child to the new location, which is fine in concept, but again messes up the animation because for some reason the actual drawing of the last frame of the animation hasn't finished by the time onAnimationEnd() is called. This causes the animation to go awry at the very end. What's happening in my case is if I layout the animated view to its new location in onAnimationEnd, the last step of the animation is being applied to the new layout, so the view looks like it is jumping around the screen. I tried a handler with no delay, and that didn't work either. Using a handler with a delayed message to accomplish the new layout works but is such a hack that I worry it may not work correctly on another piece of hardware. I could accomplish the animation by taking out the TranslateAnimation and instead do a manual animation, and in the manual one, change the layout of the view gradually (instead of transforming the matrix of the canvas) but that's a lot of work and error-prone. Any ideas? Are there tools I can use (besides manual application of Handler.sendMessageDelayed()) to accomplish an animation that actually re-lays out the view on each iteration instead of altering the canvas matrix? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Total brainstorm, never tried this, your kilometerage may vary, etc. It also assumes you're using Ant... Step #1: Put the layout file containing the MapView element that needs the API key somewhere other than res/layout/ (e.g., make a layout-template/ directory and put it there). Step #2: Create an Ant target that reads in a property file and uses and tasks to "paste" the API key out of the property file into a copy of the layout you make in the proper spot (e.g., copy from layout-template/ to res/layout/ and then paste in the key). Step #3: git-ignore the post-API-key edition of the layout file and your property file. Step #4: Possibly have your Ant target turn around and call some other target (e.g., the debug target). Side benefit of this: you can have two targets and two property files, one for debug and one for production. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _The Busy Coders' Guide to *Advanced* Android Development_ In Print! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: MyTouch Lag Problems
Yep, this is the current recommendation. In Eclair the system should be throttling event delivery to not more than 60/second, so this becomes a little less important (and the historical data more important).

[android-developers] Re: MyTouch Lag Problems
Mike, here's something to try: When handling motion events, process all of the historical data in order as if it's receiving those events like normal, then: Sleep 16 or 32 ms or so. You'll still receive all of the important stuff as historical data but you won't be flooded with events. You'll be effectively limiting the number of events that can come in to 60 or 30 per second. If you run another thread that animates or does anything graphically, you'll notice that because of the little bit of sleep on the UI thread, your game thread will continue running smoothly instead of getting chopped up from having to share so much CPU. I'm not sure if Dianne would recommend sleeping like that, but it was recommended by a speaker at Google IO for game performance and my tests showed that it is very helpful in situations where moving-touch processing is causing lags.

Ok, with symbols, it becomes clear that System.gc() is running (triggered by a JNI call up to Java) and is barfing on something it finds, likely because of an invalid DeleteLocalRef() call in my C code somewhere.

[android-developers] Re: Is it possible to use the accelerometer in a background service?
I register a listener to orientation sensor from within a background
service with no trouble. Perhaps the following code may help. These
methods are called from my service's onCreate and onDestroy methods:
private void startMonitoring(){
SensorManager lMgr = (SensorManager) getSystemService
(Context.SENSOR_SERVICE);
try{
lMgr.unregisterListener(this);
} catch(Exception e){
Log.d(ScreeblService.class.getSimpleName(),
e.toString());
}
List lSensorList = lMgr.getSensorList
(Sensor.TYPE_ORIENTATION);
if(lSensorList == null || lSensorList.size() == 0){
throw new RuntimeException("Orientation sensor not
available!");
}
// assumes that this class implements
SensorEventListener
lMgr.registerListener( this, lSensorList.get(0),
SensorManager.SENSOR_DELAY_NORMAL );
}
private void stopMonitoring(){
SensorManager lMgr = (SensorManager) getSystemService
(Context.SENSOR_SERVICE);
try{
lMgr.unregisterListener(this);
} catch(Exception e){
Log.d(ScreeblService.class.getSimpleName(),
e.toString());
}
}

[android-developers] wifi RA certificate issue
hi all, Have you notice that user is not able to import WIFI RA certificate to android. i'm using HTC Hero and i was really surprised when i failed to add new certificate to my wifi connection. it is possible even on symbian so... you can edit advanced settings and then select add new certificate, but than nothing happens like there would be only todo comment block in code... I hope somebody will fix it because i don't want to root my phone in order to have this functionality available. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] how to get stack of activities?
Hi all, I'll explain why: Assuming that my activity stack is ABC. (activity A is running and the next activity is B). I have to write a code that performs the following action: if A dies and the next activity to be executed is B, then recreate B. If the next activity is not B, do nothing. This is the reason why I want to know whether there is a way to see what is on the activity stack.

[android-developers] can't bind to a local service.
I have the following base activity.

service;
service = binder.getService();

};
A derived activity fails on the call to cast a binder --
LocalService.LocalBinder binder = (LocalService.LocalBinder) service;
fails with this on the call stack --
InvocationTargetException.(Throwable) line: 56

[android-developers] How to listen for any change in the contact database
Hi,
I am trying to listen for any change in the contact database.
So I create my contentObserver which is a child class of ContentObserver:
private class MyContentObserver extends ContentObserver {
public MyContentObserver() {
super(null);
}
@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
System.out.println (" Calling onChange" );
}
}
MyContentObserver contentObserver = new MyContentObserver();
context.getContentResolver().registerContentObserver
(People.CONTENT_URI, true, contentObserver);
But When I use 'EditContactActivity' to change the contact database,
My onChange function does not get called.

In order for your test app to be able to access the main app's classes at runtime, you need to specify a instrumentation tag in your test app's AndroidManifest.xml.

It all depends on how the objects appear in the heap. The current garbage collector does no compaction, but it will release pages inside of the heap that are free.

[android-developers] Re: Dialing IVR Systems, or sending DTMF tones after a call is made
Hi,
After studying the code and trying a few different ways to do this,
noting that in the Emulator the code works fine
I come to believe that its a HTC Hero Issue. Unforunately I do not
have a G1 to test on.
If anyone does have a G1 they could test the code let me know I will
send you the code.
Just to explain what is happening on the HTC Hero. When I try to send
it a number with comma's it removes them, even when I try to use ;ext=
to send the IVR commands it fails even though on the emulator it asks
me if I want to send the tones. I have tried ACTION_DIAL and
ACTION_CALL and both do the same thing, it starts to dial the number,
you hear the first tone come out of the speaker phone and then I see
this error below in the LogCat
09-09 19:33:45.721: ERROR/AudioService(63): Invalid routing action.
Node A2DP does not exist.
I have tried numbers i.e. without extra chars and it works, so the
code is fine.
I have encoded the hash as per this discussion
http://groups.google.com/group/android-developers/browse_thread/thread/e8904c82a2c4a333/d8452b707b38b20b?q=internal.telephony#d8452b707b38b20b
I couldn't find in the code where that error message "invalid routing
action" exists, but I see that in the AudioManager there is some code
to fix a bug that was in the eclair release, which talks about
MODE_INVALID. Not sure if I am off the scent here though.
Either way, I am not sure if this is a HTC Issue or a Android Issue.
If ANYONE has a G1 or HTC Hero and would be willing to test the code,
please let me know. ANY HELP would be appreciated
Regards
Mark

That's a good point. In addition to what I mentioned, I guess I'm really interested in ALL the API's, regardless of how they are implemented.

[android-developers] Re: onReceive not triggering for SEND / image
Here is the nudge you wanted...
Your intent filter needs to be set on an activity. The code you
posted shows it as a Broadcast Receiver.
Change:
to
and move all your stuff from onRecieve to onCreate. That should take
you forward.
Good luck!

That depends on how many third party UIs you are seeking to have built for your app. If the answer is "zero", then you probably do not want a separate process. > what are the pros/cons of using a separate process with AIDL vs. a > local service? Pros: If you are making a public API for third party UIs to use, this is your only practical option. Cons: Extra memory usage. Extra CPU usage when communicating between them. Extra application complexity.
