[android-developers] Android c++ service at boot time

[Mr cool]

I need to start a service at boot time in android i don't use broadcast 
receiver  , i wrote a service in c++ because i need access driver libusb 
layer to communicate with my extrernal device ,the service is working 
properly if i started manualy,if i want to start the service at boot time 
means i need to edit inir.rc file in android if i do that it also working 
good .but the problem is i cant edit the init.rc in all devices. i put my 
service in Sytem/bin location and edit the init.rc file as follow

service sampleservice/system/bin/sampleservice
  oneshot
  disable

for manualy i started the service from terminal like this

#./system/bin/sampleservice
but i cant start the service at each and every time when system restarts do 
have any idea to start the service at boot time with out edit init.rc

Re: [android-developers] Parser

[Kristopher Micinski]

Ah, that makes sense, I've seen a similar thing in ORM-y things for
Java.  My arguments against static code bloat are also somewhat
invalidated by the fact that most JSON libraries will be small
footprint by design.

Does this imply there's a way to specify different Bluetooth ports, if the
port(s) exists? I have never heard of Bluetooth using ports like TCP. If
you're just making an example, then please disregard this and above.

[Meena Rengarajan]

 ACTION_MOVE in my app - I could be able to draw but not visible when im
drawing and while moving my finger on a screen . Once after i release my
finger , i can be able to see what i drew on the screen completely. When
i'm trying to draw with my mouse, continuity is not good . Appearing as
dots when iam moving my finger on the screen. Once i released my finger
what i drew it appears fine !

[android-developers] Multi-Page Form with Fragments and Tabs

[Evan Ruff]

Hey guys,

I was hoping someone could give me a little insight as to how I can make my 
multi-page form work a little better. Currently, each page (two pages) on 
my form is a separate fragment. I use the ActionBar Tabs to display the 
pages and then a Next button in each page that switches the tabs to the 
next page. All validation is done on the "Save" button on the last page. 

Everything is working well, but I'm having a little issue with the back 
functionality. I'd like to be able to create/pop back stack activities when 
the user switched. As it is now, he just gets tossed completely out of the 
wizard, not returned to the previous page (tab).

How should I handle that? Any input would be appreciated! 

Oh, I'm targeting API 14.

Thanks!

Evan

[android-developers] Switching IME/Keyboard once only

[brandall]

My application has an inbuilt IME which the user has set to their default. 
In certain situations within my app (I won't bore you with which), I need 
to automatically switch to an alternative keyboard, but just for that one 
view - as soon as the user clicks on another view (or exits the 
application), it will return to my default IME.

I've tried so many options to accomplish this, but enabling another IME in 
any way is making it the users default IME from then on.

I have the imeToken, so switching to another IME is not a problem, but 
making this temporary is proving impossible Displaying the input method 
picker is a cumbersome method.

Is this by design and am I therefore drawing a blank?

Re: [android-developers] Android Bluetooth: I get "Connection Refused" after unpairing two devices, invoke user pairing, and accepting/listening connections.

[Kristopher Micinski]

That's not how it works: Bluetooth is built on top of RFCOMM, so it's
more like a serial channel.  It's merely presented with a socket like
interface to wrap the behavior.

Yes, you can specify ports, but I think you may have to use Reflection on 
Android.


This will give you a connection to port 17:


*BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();*
*
*
*BluetoothDevice device = adapter.getRemoteDevice(address);*
*

On a Windows server, you would change BT_PORT_ANY to a number between 1 and 
30.  

There is more info here:

http://msdn.microsoft.com/en-us/library/windows/desktop/aa362899(v=vs.85).aspx

"The valid range for requesting a specific RFCOMM port is 1 through 30."

[android-developers] Infrared support on Android

[flsobral]

Hello,

I have a customer interested in infrared communication (IrDA) between 
android and other devices, more specifically with the Motorola tablet MZ608.
I noticed the tablets MZ608 and MZ616 are both equipped with IR Blaster, 
but the specification of the model MZ608 does not mention infrared support, 
while the specification of the model MZ616 explicitly mentions infrared 
support.

I contacted Motorola support and they said this isn't supported by neither 
of them, only the "remote control" function is supported.
That was unexpected, to say the least. I can understand if the MZ608 
doesn't support IrDA, after all the specification only mentions the IR 
Blaster, but what about the MZ616?
It would be nice to be able to use a Motorola tablet, after all, it was my 
customer's first pick, but unless the Motorola support got it wrong, we'll 
have to use another device - which (finally) leads to my question:

Has anyone here ever developed an application that uses infrared 
communication on any Android device? Which one?
How did you get access to the manufacturer's API for infrared communication?


Thanks in advance,

Fabio.

Re: [android-developers] Android Bluetooth: I get "Connection Refused" after unpairing two devices, invoke user pairing, and accepting/listening connections.

[Kristopher Micinski]

So there is port emulation you can use if you use reflection, but it's
kind of wacky and doesn't really work like vanilla TCP: so it's
helpful not to think of it that way.  You can read about it here:

http://www.palowireless.com/infotooth/tutorial/rfcomm.asp#Port%20Emulation%20Entity%20:%20Serial%20Flow%20Control

But still, in this example, I'm not sure why you'd want it?

Re: [android-developers] Catch network traffic?

[Robert Greenwalt]

well, tcpdump can record all traffic off a rooted device, but it won't tell
you which app sent it.  You could run just the app though.  Weeding out the
system traffic shouldn't be too difficult.

[android-developers] Fake GC ?

[Fábio Balancin]

Hello,

I'm working on android project with XML layout and I have a little (but
despicable) problem.

When I set one activity with xml layout using a layoutInflater (i'm in
fragment) I close this activity and load it again, then Android heap not
release all objects of memory, and I have a little bytes more on each
reload. Doesn't GC working correctly ? How I fix that ?

My Android Device is a 2.3 version.

Thanks !!

[android-developers] How to compare a user input and then call a webView?

[Dan Uff]

Hi all:

This may sound like a basic question, but here goes

I am accepting input from a user from an EditText field.  When he/she types 
in a route number (example: 101) I need to call a webView based on that 
number - showing a schedule for that route number.  I don't have any 
example code yet, because I have no idea how to set this up in Android (I 
am coming from iOS experience).

I am using Eclipse as the programming environment.

Thanks,
Dan Uff

Re: [android-developers] Fake GC ?

[Kristopher Micinski]

In Android you never really "close a screen".

The system will --- when it feels necessary --- destroy the activity:
this sets its master view to null and at that point the view will be
garbage collected (eventually).

This is a core concept in Android: your application doesn't "close"
the same way it does on a desktop.  There are always things that you
have to watch out for: in this case the salient detail is not to keep
`Views` in static objects.  (This will cause your app to leak views
when they *are* destroyed and recreated, say by a reconfiguration when
the user rotates the screen.)

[android-developers] Re: Fake GC ?

I notice that you say game engineer in your signature and mention Android 
2.3. Does your activity create Bitmap objects by any chance? If so you also 
need to recycle them when your activity stops.

[android-developers] Animating markers on Google Maps V2

[Maksim Golivkin]

I am working on a map centered game where I track locations of people and 
display them on the map for each other to see. As people move, I want to 
animate a marker from his current to his latest position. Every person has 
a direction, so I need to rotate marker appropriately.

What is the best way to do it using the new Google Maps API v2?

More expanded version:

New API has solutions for a) moving the camera using CameraUpdate and such 
b) moving a marker to a different position, by simply using 
Market.setPosition .  However, changing an icon of the marker (I would show 
rotated image along the direction of the movement) doesn't work. It seems, 
one needs to clear all the markers from the map to make the icon change. Is 
there any better way to do it?

[android-developers] Re: How to compare a user input and then call a webView?

[Nobu Games]

Set a 
TextWatcheron
 your EditText. When your watcher gets notified about changed text you 
can immediately pass that input on to your WebView. In order to avoid 
repeated calls to your WebView with incomplete user input you could rewrite 
your TextWatcher to start a timer when text has changed. The timer waits 
for one or two seconds until it updates the WebView. It gets cancelled / 
reset by your TextWatcher as soon as the text changed again.

Re: [android-developers] Android Bluetooth: I get "Connection Refused" after unpairing two devices, invoke user pairing, and accepting/listening connections.

[tom_mai78101]

I don't think ports matter in this case. In fact, I don't need ports. 
Thanks anyway.
 
*BEWARE: Wall of text*
 
I have now narrowed down my problem, hopefully reaching a conclusion soon. 
I'm having trouble with fetching one single UUID for two devices to use. 
Here's a picture of what I have logged by using android.util.Log.
 

 
Here I have two devices, namely HTC #1 and HTC #2, both of them running 
Android 2.3.5. Each device has my app installed and debugged at the moment. 
The app fetches a UUID from the other remote device using reflection 
method, invoking Bluetooth.getUuids(). (i.e.: Device #1 fetches a UUID from 
Device #2, while Device #2 fetches a UUID from Device #1.)
 
The UUID for both devices are shown in the red box. According to this 
answer here , it said I need 
to use the same UUID for use with
BluetoothAdapter.listenUsingRfcommWithServiceRecord() and 
BluetoothDevice.createRfcommSocketToServiceRecord().
 
However, I realized that using the same UUID that was pre-fetched using 
BluetoothDevice.getUuids() 
w/ reflection for both BluetoothServerSocket.accept() and 
BluetoothSocket.connect() is wrong. Either I have to use UUID.randomUUID() 
or BluetoothDevice.getUuids() w/ reflection in order to obtain a UUID. It 
doesn't matter if it's randomly-generated, or fetched from a remote device, 
I have to obtain a UUID from some place, don't I?
 
Below is the sectors of my application. The Accept and Connect sectors 
implement the Runnable interface.
 


It probably doesn't relate to the main problem at hand, but it shows how I 
was doing with the obtained UUID. The UUID is used in the Accept and 
Connect sectors, where it handles BluetoothServerSocket.accept() and 
BluetoothSocket.connect(), respectively.
 
*Now, summarizing the narrowed problem: What can I do in order to obtain 
the same UUID for two devices? *The code below doesn't work:
 


The variable, localData, is null after executing. What am I after? I'm 
trying to obtain the same UUID from one device (i.e.: Device #1), in which 
all other devices (i.e.: Device #2, Device #3, etc.) can also fetch after, 
and use it to connect to the first device (i.e.: Device #1).

[android-developers] MediaPlayer suddenly stopped working in Android 4.2

[Brill Pappin]

I've been working on an app that plays MP3 files and have started with out 
with the lowest supported android version and working upward toward JB.

For some reason the MediaPlayer starts generating an error in Android 4.2 
when it has been working just fine until now.
Nobody seems to know what has changed or how to work around it. The only 
suggestions I've found so far are to do with permissions, but unless they 
have changed radically for external storage, the MediaPlayer should have 
permission to read the files.

Here is some relevant information. Notice there is no stack trace, just a 
message printed out.
(I've included some of my debugging output for reference).

02-14 12:24:05.210: I/MessageListFragment(29567): *** FILE [exists:true]: 
file:///storage/emulated/0/Android/data/com.primaltech.vvm/files/audio/V2013011508.mp3
02-14 12:24:06.001: D/MessageListFragment(29567): Local data file: id=1, 
rid=V2013011508, 
uri=file:///storage/emulated/0/Android/data/com.primaltech.vvm/files/audio/V2013011508.mp3
02-14 12:24:06.001: D/MessageListFragment(29567): Preparing to play: 
file:///storage/emulated/0/Android/data/com.primaltech.vvm/files/audio/V2013011508.mp3
02-14 12:24:06.011: E/MediaPlayer(29567): error (1, -2147483648)
02-14 12:24:06.051: E/MediaPlayer(29567): Error (1,-2147483648)
02-14 12:24:06.051: E/MessageListFragment(29567): what: 
MediaPlayer.MEDIA_ERROR_UNKNOWN

So far I have seen this on both a Nexus 7 and a Nexus 4 running JB 4.2.1, 
it seems to work fine for the prior versions that I've been able to test 
(4.0.4, 4.1.1).

[android-developers] Re: Switching IME/Keyboard once only

[Brill Pappin]

Unless things have changed recently, you can't programatically change the 
input method because its too great a security risk.

e.g. I could replace your keyboard with one that looked exactly the same 
but captured everything you typed and sent it to my mob friends. In a day I 
could have all your passwords, credit card numbers, security codes, love 
letters, etc.

By forcing you to ask the user to change it, it gives the user the 
opportunity to decide if they trust the alternate input method.
Of course, I'm not as up to speed on the most recent android versions, so 
if things have changed, someone will point it out I'm sure.

[android-developers] Re: best way to copy an existing application

[Brill Pappin]

Really it depends on what he's got in the original app. Even just a 
provider is going to be trouble if he simply turns the whole thing into a 
library.

 Put the different resources into the Application Projects.

[android-developers] Re: Problem while sending JSON from android app to Java servlet using post method

[Brill Pappin]

This isn't really an Android specific problem.
However, your content type is wrong if you are sending the JSON as a POST 
parameter. You should be using form encoding or even multipart.
If you a dumping the JSON into the POST data then you should likely be 
using a PUT instead of a POST.

Are you trying to set the margin on the outermost level of your item
layout? I don't think that's supported. Setting a margin on a view nested
inside your item layout should work though.

Re: [android-developers] Re: Binding to Android service in an external jar doesn't seem to be working

Sure,

Although at the same time, if you are doing this, you really *should*
be using an Android library project: it just makes it simpler for the
users of the library.

[android-developers] some help with an stack trace

[Jokin Cuadrado]

I rolled and update of an app, and acra now it's reporting some crashes. I 
tried to search what's happening but i find nothing relevant. It seems that 
sometimes it doesn't find the analytics library and it's AnalyticsReceiver, 
but there's also a reference to com.google.android.maps which I don't 
understand why is there.  May be it's because the maps library it's not 
installed and the AnalyticsReceiver it's deceiving me?

Thanks in advance.

[android-developers] Re: Switching IME/Keyboard once only

[brandall]

Thanks for your reply - You are able to switch the 
keyboard programmatically if you are the current IME token holder. My 
struggle is to request this change temporarily.

[android-developers] Ratings & Reviews SDK???

[pawpaw17]

I want to implement ratings & reviews in my app, and I'm about to write 
some server side code to do it. Does anyone know of a decent 
ratings/reviews SDK that is restful and appropriate for use in a native 
app? Just wondered if anyone else is in this boat?

Would love to hear from anyone on this topic.

Best!

What do you mean "get the id"?

If you mean refer to it in code, it's just "R.id.existing_list".

[android-developers] Re: MediaPlayer suddenly stopped working in Android 4.2

[Alex Lockwood]

The "emulated" directory you see in the pathname doesn't mean he is using 
the emulator. This directory structure was modified in API 17 due to the 
addition of multiuser support.

I'm having the same problem... trying to figure it out now.

[android-developers] Testing In-App billing: Is a factory reset necessary?

[Jungle Jim]

I am developing an app that will include in-app billing. I understand that 
in order to test the billing functions, I need to set up a test google 
account.

Here's what google's developer site says about the test account:

http://developer.android.com/google/play/billing/billing_testing.html#billing-testing-setup

To perform end-to-end testing of In-app Billing, the primary account on 
> your device must be one of the test 
> accounts
>  that 
> you registered on the Google Play site. If the primary account on your 
> device is not a test account, you must do a factory reset of the device and 
> then sign in with one of your test accounts. 


 I have two Android devices I can test with, but I don't want to do a 
factory reset on either one. Is there some way to do the proper testing 
without a factory reset? Thanks.

You need to give details. It's best if you can provide an example of code 
that creates the behavior.

http://sscce.org/

and explain exactly what you did and copy and paste any error messages into 
your post and describe 
precisely how the results you got differed from what you expected.
