[android-developers] Re: How can users enable compatibility mode?

[Piren]

You are using a tablet right? :)
Big screen support only shows the "Zoom" icon on large screen devices 
(tablets, maybe phablets as well, never seen it on a Note though)

[android-developers] Re: Applications that relies on external datas.

[Piren]

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).

If you are using Admob you can use house ads to promote your app.
Set it show house ads only for a week or two, then return back

[android-developers] MediaPlayer does not play ringtone when activity started from locked screen.

[Inn0vative1]

I am writing an alarm (kinda) app, which registers a broadcast intent with 
AlarmManager with the RTC_WAKEUP flag, to go off at a specified time. 
Works...

When the broadcast is received, the receiver starts an activity that plays 
a ringtone with MediaPlayer using the STREAM_ALARM stream, and does some 
other stuff. All that works, but if the broadcast is received when the 
screen is off, the activity is starts up correctly but the ringtone does 
not play. Works fine and plays ringtone if received when the screen is on 
and unlocked.

Are there any additional flags to set? Here's the code of the activity 
started from the Receiver.

public void onCreate(Bundle bundle) {
super.onCreate(bundle)
...
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
ringtonePlayer = new MediaPlayer();
...
playRingtone();}
private void playRingtone() throws IllegalArgumentException, SecurityException, 
 IllegalStateException, IOException {
ringtonePlayer.setDataSource(prefs.getString(getRingTone(), 
RingtoneManager.getActualDefaultRingtoneUri(this, 
RingtoneManager.TYPE_RINGTONE).toString()));

ringtonePlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
ringtonePlayer.setWakeMode(this, PowerManager.PARTIAL_WAKE_LOCK);
ringtonePlayer.setLooping(true);
ringtonePlayer.prepare();
ringtonePlayer.start();
Log.i(LOG_TAG, "Ringtone started");}

If you mean 'android.os.Handler' there is no such method 'Post()'. Did you 
mean 'post()' or a different type?

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

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()'.

[android-developers] Re: Handler Post sequence

[bob]

I looked at the source, and I'm not sure CodeA will execute before CodeB.

Maybe try this?

handler.postAtFrontOfQueue(CodeB);
handler.postAtFrontOfQueue(CodeA);

Or create a new Runnable that simply calls the run methods on the other two 
Runnables in sequence?

Thanks.

[android-developers] Re: Handler Post sequence

[Filipe]

Hi,
 
Thanks, this solves this problem.
But in my project I have severall situations where I need to post code to 
run on the UI thread.
 
If I call:
Handler.Post(CodeA)
Handler.Post(CodeB)
 
Can I be sure that CodeA executes before CodeB?
In some situations it does not seem like it.

[android-developers] Re: Compatibility mode issues on 4.x

The documentation pertaining to your question is confusing:







It sounds like 320 may very well be a "*magic number"*, and that nothing 
greater or lesser will work.


But the docs do not seem to state this unequivocally.

Re: [android-developers] Re: Compatibility mode issues on 4.x

[Mark Murphy]

If you read the documentation:

http://developer.android.com/guide/topics/manifest/supports-screens-element.html#largestWidth

it says:

"Note: Currently, screen compatibility mode emulates only handset
screens with a 320dp width, so screen compatibility mode is not
applied if your value for android:largestWidthLimitDp is larger than
320."

[android-developers] Re: Compatibility mode issues on 4.x

[user123]

Ok, the issue is confirmed. I created a brand new project with a blank 
activity, and ran it on a tablet.

The only modification I did was in the manifest, as follows:





Then the app goes in compatibility mode - "Hello world!" is zoomed. Fine.

But if I change to *321 dp *- It doesn't go into compatibility mode.


I tested with a Nexus 7 tablet, Nexus 7 emulator, and 10.1 inches tablet 
emulator.

Is this a bug?

Why are you using "make"?

You don't use "make" to make Android applications. The usual tool is Ant.

Are you doing something outside of the normal Java world of Android?

Android uses Java, not gcc.

I must misunderstand what you are doing. This is a newsgroup for Android

development, where such considerations really don't apply. What has them

What repo?

How about in turn you take the time to tell us what you're doing that 
involves "make", and what "repo" is, and why you need them to develop 
an Android app.

[android-developers] Re: How can users enable compatibility mode?

[user123]

Well, then that's my question. Why the device is not showing them. I put 
both min and target SDK to 8. I also don't have manifest element for 
explicit support of large screens. So this option should appear. But I 
don't see it. Just the action bar, with 3 dots for my custom menu and 
that's it :(

Well, duh. 

Look at the indent level of the replies. Of *course* that's a reply to 
George Baker,
as indicated in my post by the attributions.
 
I don't know why you kept repeating that. It was already obvious.

[android-developers] Mirroring animation?

[Boyd Speer]

Using Touch class that implements onTouchListener (and matrix) to drag a 
crosshairs on an image aiming pad, how can I have the movements control another 
dot (imageview) in a another part of the screen within a rectangle proportioned 
the same (but a different size) as the aiming pad? The dot would mimic the 
moves the user makes with the crosshairs ...


Is the answer a custom listener, broadcast receiver? ... Or somehow calling the 
main class methods from within the Touch class ?  
Any suggestions greatly appreciated ...

Take a look at my newer thread:

I added the support library and used SupportMapFragment and still an

Fragments are not available in GB unless you are using the compatibility

[android-developers] Re: Handler Post sequence

[bob]

Maybe use something like this?

View myView=findViewById(R.id.myView);
  myView.getViewTreeObserver().addOnGlobalLayoutListener(new 
ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
//At this point the layout is complete and the 
//dimensions of myView and any child views are known.
}
});

[android-developers] Handler Post sequence

[Filipe]

Hi,
 
Does Handler.Post() respects the "Post" sequence?
 
 
A simplifyed version of what I am doing in my Activity is:
 
public void onCreate(Bundle savedInstanceState)
{
 super.onCreate(savedInstanceState);
 setContentView(new AbsoluteLayout());
 new Handler().Post(new Runnable() {
public void run() {
 CheckView();
}
});
}
private void CheckView()
{
 int 
myHeight=getWindow().findViewById(Window.ID_ANDROID_CONTENT).getHeight() ;
}
 
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 
graphic processing has been done, without PostDelayed() ?
 
Thanks
 
Filipe Madureira

I agree - testing 80 sounds like a good idea to gain more info about what
may be happening.

 Hi Developers,
 I have an background service which connects my server with a TCP
 connection.
 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(AT&T, 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.

Any suggestions?

Re: [android-developers] Re: Sprint 4G(WIMAX) tcp connection problem

[bob]

 

Is it an option to run the XMPP server on port 80?

Or perhaps just set up a test server on port 80 to explore the hypothesis 
that this will resolve the problem?

Alternatively, you could also create a proxy that runs on port 80 and acts 
as an intermediary.


Thanks.

Re: [android-developers] Re: how to create a custom gauge in android

[bob]

 

If you don't use *save*() and *restore*() and something gets drawn after 
your needle, it will also be rotated just as the needle was rotated.


So you would probably use something like this:


*canvas.save();*


canvas.rotate(45, 100, 100);

canvas.drawBitmap(…);


*canvas.restore();*


Thanks.

Re: [android-developers] Sprint 4G(WIMAX) tcp connection problem

[Robert Greenwalt]

Thanks Long Pu for the reasoning for not using GCM.

You only have this problem on sprint wimax, correct?  Have to tried very
frequent keep-alives?  Figuring out roughly what the required period is may
help us find the cause.  We can talk with Sprint and Samsung about it, but
the timeout info would be useful before that.

[android-developers] problems with android support library

[John Merlino]

In my Android SDK Manager, I have the Android Support Library
installed. In my Downloads/android-sdk-macosx/extras/android/support
directory, I have a v4, a v7, and v13. I copied android-support-v4.jar
to the libs folder. Right clicked and selected Build Path > Configure
Build Path. In the activity layout I added the following (using
supportmapfragment rather than mapfragment):

http://schemas.android.com/apk/res/android";
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.SupportMapFragment"/>

But still I get this error:

04-16 17:42:00.928: E/AndroidRuntime(363): FATAL EXCEPTION: main
04-16 17:42:00.928: E/AndroidRuntime(363):

[android-developers] Re: Applications that relies on external datas.

[mbaroukh]

If using fragment, I suppose I could make only one activity that will 
handle logic (and data download) that will do what AndroidApplication 
should and many fragment that won't have to manage more than their own 
state. 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.

 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 wan"t 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.

 So my question : How do you handle this kind of problem ?

 Thanks for any advice.

You can have a fragment that handles the whole thing and use it in both 
activities (i personally think that the code to handle the fragments would

Doing it in OnCreate of the application wouldn't help much, you'd still

[android-developers] Re: how to create a custom gauge in android

[bob]

Break the needle off of that image and put it in it's own image.

Then use this function in *Canvas*:

final void *rotate*(float degrees, float px, float py)

Also, you will call *drawBitmap* in the Canvas class.

Of course, you will want to *save()* and *restore()* the matrices before 
and after the rotation.

Thanks.

[android-developers] Re: Applications that relies on external datas.

[mbaroukh]

Service or not every activity must implement a logic to wait for the 
download to complete isn't it ?
So it must have a logic for it own process and a logic for the download.
That make those activities more complicated than they have to be.

Is it and Android design problem that have no solution and which we have to 
live with or do I missed something ?

[android-developers] Re: Applications that relies on external datas.

[mbaroukh]

"Don't let the "UI" handle the data (activity), add a Business Logic layer 
to do that."

I totally agree with that and data is loaded from a separate layer actually 
called by activity A.
But I was looking how to avoid to have each activities call the 
initialisation of this layer.

It seems obvious that the initialisation should be done in onCreate of 
AndroidApplication.
In case of resume, onCreate() is called.
But then, the screen is black and we have no way (as I know) to provide a 
layout on screen that, anyway would have not been displayed because we are 
on the UIThread.

I hate to have to tell every activity that starts to
- check if data is available
- not available then use asynctask to display dialog and download.
- and don't forget to do nothing in onResume() in this case and wait for 
the download to finish before calling what have to be done onResume()
- .. and lot of other case to handle.

That's a lot of boilerplate code to do this.
I was hoping there was something I was missing.
It would be so simple if we could handle ActivtyLifecycle somewhere.

Do I have to resign to see lot of code that will be copy/pasted and will 
introduce errors ?

Use a Service to retrieve and manage the data, Bind the service from 
Activity A and B.  If the data is available use it, if it not download it 
(in the service).

[android-developers] Re: Applications that relies on external datas.

[Piren]

Don't let the "UI" handle the data (activity), add a Business Logic layer 
to do that.

I.E - create a class that is responsible for managing this data. if data is 
present, load from DB, if not, download for the net. Then let whichever 
activity that needs the data, interact with that class instead.

BTW, making "order" assumptions for activities on android is a mistake, 
exactly for the reasons you specified. You should not base your code in a 
way that assumes something happened earlier in the app. And if you do need 
to make that assumption, make sure the code works even if the assumption 
turns to be wrong. In some cases, by forcing the order (dont let activity B 
launch normally and revert to A).

[android-developers] Applications that relies on external datas.

[mbaroukh]

I have a problem that appear on every new developpement.
I never found a clean way to handle it so I'm asking for your help.

Suppose you have an app that rely on data coming from network.
Every activity needs those data.

So my approach actually is to handle the download by the first activity and 
store it so it will be widely available.
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 wan"t 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.

So my question : How do you handle this kind of problem ?

Thanks for any advice.

Re: [android-developers] Sprint 4G(WIMAX) tcp connection problem

[Long Pu]

We have to consider multiple platforms(iOS, Android, Blackberry). On iOS,
push notification
is not an option for our application.  If use GCM, we need  another extra
special design especially for android.

[android-developers] Converting PCM to AMR-WB using AmrInputStream

[Raneez]

My Android application needs to convert recorded audio in WAV to AMR-NB and 
AMR-WB. And i am done with converting to *AMR-NB* using *AmrInputStream*.

In AmrInputStream, the value for SAMPLES_PER_FRAME is hard coded to *8000 * 
20 / 1000* and the audio has no changes even after changing 
SAMPLES_PER_FRAME to *(16000*20/1000)*.

Is it possible to convert PCM to *AMR-WB (16 khz)* using AmrInputStream ?

[android-developers] Re: How can users enable compatibility mode?

[Piren]

You don't enable it on the device.. the device does it for you.
If the app wasn't designed for a tablet and meets the conditions (like 
having the targetSdk below a set level and/or having not declared it is 
destined for big screens) then the device will show the proper 
  compatibility options like the Zoom button or the 3 dots.

[android-developers] How to take the focus on to the softkeyboard

[Shashidhar]

Hi,
 I am working on a project which does not have any touch interface. All it
has is a remote control with 6 buttons (Enter, Back, next, prev, up and
down arrow keys). Using these button we need to control the navigation of
the app.

Coming to my problem here, I have an edit text which shows the soft
keyboard when it takes focus. Is there any way by which I can take the
focus on to the soft keyboard.  I mean, I should be able to use the next,
prev, up and down arrows buttons of my remote control to
move across the soft-keyboard keys and type in into the edittext.


Thanks,
Shashidhar
