[android-developers] Re: Applications that relies on external datas.
that's not the point of the fragment... i meant that the fragment should handle both the logic (and data download) and the UI. then you can just plop it in any activity you want and you're set. Regarding the Application onCreate - Yeah, it will be before anything else, but you dont know how long it would take to finish. it's as pointless as doing it in the first activity. (being a UI thread makes no difference, it's the same thread as in the activities... either way you'd have to pass the work to the background).

But that did not seems clean to me. Doing it in OnCreate of the application wouldn't help much, you'd still have to program all activities to know the data is still not there.. so not much gained here. I don't understand why : when application stats, onCreate is call before anything else. I can then load sme (small) data statically (eventually ...) and I am sure I can rely on them while the application is not evicted from memory. On the application resume, if application has benn destroyed, onCreate() is called again so there seems not to be any problem here. Except the (bad) fact I'm on UIThread, of course. I'm surprised there no library to handle those activity LifeCycle but I imagine it must be something tricky. I suppose the best option would be to use the same process as http://androidannotations.org/ to generate all the boilerplate code at compile time. Anyway, thanks a lot for your answer.

No other activity will be launched before data is stored so every activity will be sure it will be always available. Suppose we have the sequence Activity A (that load data) Then Activity B that use data Then application goes to background is killed by system is wake up on B == No problem because data is stored so it will be available and all will be fine. But, suppose that before to be waked up, data is cleared. The application wake up on activity B with no data available. There will be a NPE. Of course, I can add in the OnCreate() method of application B that, if data is not available, launch activity A and finish. But I also have to handle it in onResume(), on Pause(), on Create(), onDestroy(). And I have to make it in all my application's activities that use data which is not really clean. I don't wan't that all my activities inherit from a single one. I don't want to have only one activity with lot of fragments. The best option whould have been that the Android Application object is able to handle startup and change the first intent in certain conditions. then, if we are going to run B and data is not available, lauch A instead. but sadly, this is not possible.

[android-developers] Which is more suitable for uploading large files? a service on separate process or ...
Hi, When an application needs to upload many large files, which would be a better solution: 1) Doing this on a separate process (i.e. remote service)? 2) Using a separate thread (or AsyncTask)? Is there a clear and definite answer to this? The application, by the way, is uploading things all the time - usually very small chunks of data. Every now and then it needs to send large files, so I want to do that with a separate mechanism then the one I am using.

Re: [android-developers] Re: Compatibility mode issues on 4.x
Thanks, Mark. I should have done a better research. So this leads to a quite stupid situation. I did the work to optimize layout for xhdpi devices, like the Galaxy Nexus, and it looks quite well. If I set the compatibility mode to 320dp, this willl be lost on all these devices. Samsung Galaxy s3/4, HTC One, etc, have screen sizes which will make my app go in compatibility mode! For me this is a bug, specially because the larger the screen, the more sense it makes to have the option available to use compatibility mode. And precisely then it's not possible. Am Mittwoch, 17.

This is not exactly what I want, but anyways, maybe worth to mention, these options didn't work. I couldn't find anything on the device to switch to compatibility mode. I used a Nexus 7 with 4.2. Now there's the part which I need - and I also can't get it to work. To force compatibility mode, it I have to use this element: supports-screens android:largestWidthLimitDp=320 / When I let the value 320 there, my Galaxy Nexus smartphone goes in compatibility mode. That is unwanted. The Nexus 7 also does, this is good. So I have to use bigger dp - But starting at 321, for some reason I don't understand, the Nexus 7 doesn't go anymore in compatibility mode. Is this normal? According to what I read the dp of the shortest side of the Nexus 7 is more than 500, why then it stops on 321? I would let it on 320, but I have optimized layouts for this screen size and don't want these to go in compatibility mode.

Re: [android-developers] Re: Handler Post sequence
If you mean 'android.os.Handler' there is no such method 'Post()'. Did you
mean 'post()' or a different type?
-I mean post().
I did not copy the code, I typed it to try to explain my problem, sory for
any errors on that.
I will try to ask the question in a different way:
I have a worker thread that needs to post several peaces of code to the UI
thread.
So I am using android.os.Handler post() method.
*How can I ensure that code I post to the UI is executed in the same
sequence I post it*?
Notes:
-That code needs to run in the UI thread.
-Can't use postAtFrontOfQueue() because the worker thread is posting some
code has work is getting done, so I can't reverse the call sequence to use
this function. Ideal would be something like postAtEndOfQueue.

A simplifyed version of what I am doing in my Activity is:

super.onCreate(**savedInstanceState);
setContentView(new AbsoluteLayout());
new Handler().Post(new Runnable() {
This should fail to compile if you are using 'android.os.Handler'.

You should follow the Java naming conventions, by which this method will
be called 'checkView()'.

}
Sometimes in myHeight I get the correct values, and sometimes I don't?
If I change the Handler.Post to Handler.PostDelayed(...,1000) it allways
works, so the problem seems to be that when I use Post() the CheckView()
code is executed before the setContentView.
So how can I guarantee to Post code to be executed at the end of all

Start by using the correct method name.

[android-developers] Google+ How to know if application is installed by friends
Hi, I'm trying to retrieve the people in a user's circles that have installed the current application. I have used the sample application PlusSampleActivity provided in the SDK and successfully managed to get the list of all people in the user's circles. However, I'm not sure how to get if the person have installed the application or not. The documentation available seems to be very limited... What I have found is https://developer.android.com/reference/com/google/android/gms/plus/model/people/Person.html I'm using below function but this is always returning false. (I have created a user that have installed the app and I can see this when visiting this user's profile on the web using Google+) Is there some other API that should be used? Or any other limitations that I don't know about (time until it is visible?)? public abstract boolean isHasApp () If true, indicates that the person has installed the app that is making the request and has chosen to expose this install state to the caller. A value of false indicates that the install state cannot be determined (it is either not installed or the person has chosen to keep this information private).

Re: [android-developers] Re: Compatibility mode issues on 4.x
Ahh... he might have did it wrong, but that's an over simplification... I wish you could use the same layouts for those devices... fact is you cant. DP and SP do an OK Job to fit each density, but not perfect. The same layout on the Galaxy Nexus and on the Nexus S look different enough to require modifications if you're pedantic enough or trying to fit a lot of views in. It gets even worse when screen sizes change... thats why they added more modifiers (like screen sizes) to allow more control. Heck, sometimes you'd want to use different layouts for the same screen sizes exactly because of the fact the sizes are the same - text that looks normal on xxhdpi looks huge on hdpi and text that looks normal on hdpi is tiny on xxhdpi. btw - not to confuse anyone, but it's kinda misleading to say there's no correlation between screen density and screen size... Google tried to make it so you could program regardless of their values (they didnt succeed) but they are correlated (density is defined by screen size after all :-P).

Re: [android-developers] Re: Compatibility mode issues on 4.x
I think the best solution is for you to not use compatibility mode. I think it was mainly a stopgap solution for when tablets first came out. People probably wouldn't buy a tablet if nothing would run on it. But tablets have been out long enough so that it doesn't make sense to only design an app for a 2 inch wide phone and then run it in compatibility mode on a tablet. Thanks.

Samsung Galaxy s3/4, HTC One, etc, have screen sizes which will make my app go in compatibility mode!

That is unwanted. The Nexus 7 also does, this is good. So I have to use bigger dp - But starting at 321, for some reason I don't understand, the Nexus 7 doesn't go anymore in compatibility mode. Is this normal? According to what I read the dp of the shortest side of the Nexus 7 is more than 500, why then it stops on 321?

Well, my layout is density independent.

Nobody in the company was interested in using this app on large screens, so I never got the order or time to do this work. Now this app is available but the development is suspended - I'm also not working there anymore. The app looks perfect in all smartphones. But on tabled-sized screens it has mayor errors, because of some calculations I had to do programmatically, which seem to have a problem when the screen is large, and some places where I forgot nine patch buttons and things like that. There where also a lot of backgrounds with bitmap-shadow, where the content had to be adjusted with pixel-accuracy to look correct. So, yeah, if I could, I would just put this application off for tablets, because that's was what I was told to, actually. But it's not possible.

Re: [android-developers] Re: Compatibility mode issues on 4.x
The point is - if somebody sees my app on a tablet, like now, they will think what the ...? They'll think I have no idea. But if people sees it in compatibility mode (or even better, they can't download it), they say, okay, the app was not intended for tablets! - That's a huge difference. Am Donnerstag, 18.

What about this in the MediaPlayer class? public void *setOnSeekCompleteListener* (MediaPlayer.OnSeekCompleteListener listener) Thanks.

It has a periodic timer that saves every 30 seconds which works great, but I'd like to also save immediately after the user moves the position using the seek bar. I'm using the built-in MediaController, but it doesn't seem to provide anything except for the MediaPlayerControl interface. That interface has a seekTo() method that tells the current position, but it tells it as you're dragging, so it fires off a few dozen evens as you drag it. I really don't care about any of those, just the last one. Any smart people with a tip for me here? I have a couple of ideas, I'm just not crazy about any of them...

Re: [android-developers] Re: how to create a custom gauge in android
Apparently, the Nexus 7 has no temperature sensor according to this method:
private void attachToSensor() {
SensorManager sensorManager = getSensorManager();
ListSensor sensors =
sensorManager.getSensorList(Sensor.TYPE_TEMPERATURE);
if (sensors.size() 0) {
Sensor sensor = sensors.get(0);
sensorManager.registerListener(this, sensor,
SensorManager.SENSOR_DELAY_FASTEST, handler);
} else {
Log.e(TAG, No temperature sensor found);
}
}
Thanks.

Re: [android-developers] Sprint 4G(WIMAX) tcp connection problem
It's galaxy S2. I believe the GCM works on this phone. I am wondering what GCM does to keep his socket alive. It would not seed keep alive packets in short period like several seconds, this would burn out battery very quickly. My guess is that the carrier can recognize the GCM tcp connection and only keep it alive. Cheers.

My background service sends a ping packet to my server every 4minutes to keep the socket alive. The problem is that the device can not get the packet from the server after a short time(3 seconds from my test) after the ping is sent. This app works fine on other networks(ATT, verizon). The strange thing is that if I force the device to connect to 3G(EVDO revision A), it works fine. It seems to me that, on Sprint 4G network, when an app sends a packet through a tcp socket, and then the socket is idle for several seconds, then the app will never be able to receive packets from this socket. I don't think it's related to the 4G signal, since this issue can be reproduced every time.
