[android-developers] Re: detect if an app is launched

[Pent]

If someone wants to do it for 'bad' reasons, they're not going to be
discouraged by a little extra time and extra resource usage of having
to poll for it!

Not providing an event for this just penalizes devs/users with a
'legitimate' need for the info.

Users like to do different things depending on which app they are
using (different screen brightness, timeout, turn on/off wifi for
Internet etc).

Automation apps are reduced to battery-expensive polling to provide
this currently.

[android-developers] Re: Customized Soft keyboard

[Sérgio Faria]

Have a look at 
KeyboardView.
 
You define the keyboard using a XML file like this:

http://schemas.android.com/apk/res/android";
android:keyHeight="50dp"
android:keyWidth="16.66%p" >



...

Then, in code, all you need to do is set the keyboard and set a keyboard 
listener to handle key presses.
If you manage to get the right keycodes for all keys, then you only need to 
implement this part to make it work:

protected class KeyboardListener implements OnKeyboardActionListener {

@Override
public void onKey(int primaryCode, int[] keyCodes) {
long eventTime = System.currentTimeMillis();

KeyEvent event = new KeyEvent(eventTime, eventTime,
KeyEvent.ACTION_DOWN, primaryCode, 0, 0, 0, 0,
KeyEvent.FLAG_SOFT_KEYBOARD | 
KeyEvent.FLAG_KEEP_TOUCH_MODE);

getActivity().dispatchKeyEvent(event);
}
...
}

[android-developers] Android USB host and hidden devices

[Alexey]

I am developing an Android application in which I have to communicate
to an USB device. I tried to use standart google API in my app, but
list of devices is allways empty.

Same things if i use USB device info with google api. List of devices
searched by google api is empty,

lsusb gives following results:

Bus 001 Device 001: ID 1d6b:0001
Bus 002 Device 001: ID 1d6b:0002
Bus 003 Device 001: ID 1d6b:0001
Bus 002 Device 002: ID 2226:0014

my device is 2226:0014

log of eclipse:

I/USB3G(92): event { 'add', '/devices/platform/sw-ehci.1/usb2/2-1',
'usb', '', 189, 133 }
I/USB3G(92): path : '/sys/devices/platform/sw-ehci.1/usb2/2-1'
I/USB3G(92): VID :size 5,vid_path '/sys/devices/platform/sw-ehci.1/

usb_modeswitch.d/2226_0014 &,
I/USB3G(92): excute ret : 0,err:No such file or directory

If i plug in devices like rs232 adapters, bluetooth dongle, nothing
happens,and there is no any result from API and lsusb.

Prtocol of a device is based on ezusb library. Android v.: 4.0.3
kernel v.: 3.0.8 firmware build: crane_evb-eng 4.0.3 IMLK74k 20120330

Is there are any way to access hidden USB devices via API?

[android-developers] How can I open my app with power button?

[Andrea Fasciglione]

It should be not clear, but how can i open my app with power button?
I would add this option so in case of emergency a person can press
(for example) three times the power button and my app opens.
How can i do this? [I hope it was clear...]

[android-developers] finding which application uses a port on the android device

[Ami Turgman]

Hi All,


I have an android native application which hosts a web server inside it.

I want to know which application makes requests before they are processed 
by my application.

What I have is the port of the calling application.


How can I find out which application is using this port?

I've tried looking for all processes (cat /proc/net/tcp6), but the 
application with the port I have is not listed (on a rooted device it is).


I need to find a way to find the calling application name on a regular 
device (not rooted).


Any help is highly appriciated.


Thanks!

Ami.

[android-developers] Simple attribute/style question

[Alex Fu]

I have a custom style that I want to apply to my own implementation of 
EditText. The following link is a summary of how I am trying to get 
attributes from my custom style... https://gist.github.com/2972687

My goal is to have the style applied when I instantiate this custom 
EditText regardless if it is instantiated via code or XML and for some 
reason, when I try to access the *android:textColor* attribute, it returns 
a -1. I've tried adding other attributes to my style and accessing them 
results in a -1 as well. It seems as though I can only access the *
android:background* attribute.

[android-developers] Problems with talkback in ICS

[Andrew]

I'm writing an accessibility app that seems to work ok on gingerbread 
builds and some ICS builds, but I seem to have problems with ICS samsung 
phones - particularly the galaxy nexus and s3. As soon as I enable the 
accessibility service registered for my app it seems to enable talkback for 
certain apps even though it's not switched on and I'm not doing any TTS.

Am I regsitering anything wrong here:

AccessibilityServiceInfo localAccessibilityServiceInfo = new 
AccessibilityServiceInfo();
localAccessibilityServiceInfo.eventTypes = 
AccessibilityEvent.TYPES_ALL_MASK;
localAccessibilityServiceInfo.notificationTimeout = 80L;
localAccessibilityServiceInfo.feedbackType = 
AccessibilityServiceInfo.FEEDBACK_ALL_MASK;
setServiceInfo(localAccessibilityServiceInfo);

I can't think what I can be doing wrong here. Any suggestions, it's been 
driving me mad.

[android-developers] Much time taken in data read from socket

[Azmat Alikhan]

 

I'm using sockets for data transfer from one android phone and PC, it is 
taking 15 seconds to read about 1 Mb of data. I want to improve its 
performance.

Could anyone suggest any better way to do that?

My Code is:

InputStream is= socket.getInputStream();
DataInputStream inChannel= new DataInputStream(new BufferedInputStream(in));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int oneByte;
while ((oneByte = inChannel.read()) != -1) {
if (oneByte == 0) {
break;
} 
baos.write(oneByte);
byteCount++;
}
byte[] inData = baos.toByteArray();
baos.close();

[android-developers] How can i launch my app using power button?

[Andrea Fasciglione]

It should be not clear, I'm sorry. But How can i launch my app using
power button?
I'd like to add this option so in case of emergency you can press (for
example) three times the power button and my app launch.
How can i do this?
[I hope it was clear...]

[android-developers] Wifi Power consumption optimisation

[Adam Skrodzki]

I want to write an application which will gather data from user and send 
them to router using wifi for example once in every minute (there will not 
be plenty of data rather <1kb in every minute but it is critical to send 
them quite frequently). My question is: How to optimize wifi usage? Should 
I switch it on and off every time when I'm using it? Or is there some 
sleeping mode (when wifi is switched off but after switching on it connect 
to network immediately without searching for ip etc.)   
Does it depend on android version? Is Android 2.2 ok, or do i need higher 
version (which one?)

Thank you in advance.
 Adam

Re: [android-developers] Re: Resolution Problem in Nexus One

[Adrião Neves]

I understand what you saying, but how to solve the following scenario:
- You developed an application with English (default), German, and Italian 
languages;
- A French user (whom mobile is in french and have many french applications 
in the phone) installs you application;
- Because your application doesn't have French, android chooses the default 
one, in this case English, right?
- So you application is shown in English, but what if the user just don't 
speak English but speaks Italian? How can he change this without changing 
his locale settings from French to Italian?

[android-developers] How to upload apk with new version, when previous key store is lost?

[Rashid]

Hi,

We have been developing Android apps since a while now but unfortunately *we 
lost our key store which was used to sign a previously uploaded apk*, now 
we want to upload a new version of existing live app on Google play to do 
so we need to sign new apk with different key store but Google Play will 
not accept apk signed with different key store.

Is there any way that we could upload new version of app with different key 
store as we do not want to add separate new app asap for those user which 
have already installed previous version and they deserve *to have update 
existing app rather than purchasing brand new app again?*  

Also if not possible for above statement then:
Is there any way to get complete information of key store from previously 
signed apk so that we could possibly get key store and use it to upload new 
version of app? 

Android Support: Please answer on this situation as there could be some way 
to upload apk with new version and signed with new key store.

Thank You

[android-developers] Not allowing me to install SDK as java jdk is not being recognized

[Scharlto]

Good day all,

Having an issue with installing the android sdk environment on my virtual 
machine running windows server 2008 R2. I have had success before running 
on this edition of windows so I'm not sure why this is giving issues 
now.The issue is when I boot up the .exe. file, it starts 
the installation wizard however when it checks for the version of java, it 
can't find any (even though its been installed) and won't let me proceed.

My environment specs are:
- Windows server 2008 R2
- Java JDK 6.x

Thanks for any help you can give!

Steve

[android-developers] android:onClick throws nullPointerExeption

[CaynanVictor]

Hey, guys, i had a really strange problem i was trying to do this 
tutorial:  http://developer.android.com/training/basics/firstapp/index.html , 
but as soon as i add content to the method that the android:onClick calls, 
the app breaks and throws a nullPointerExeption. i verify the code 5 times, 
and it`s exactilly equals to the one on the tutorial.

So i ignore this and try to make another project, just to implement the 
android:onClick, and again the same problem as soon as i add any code to 
the method that de onClick has the app crash.

if anyone can help i`ll be very greatful.

thanks...


P.S: sorry for any english mistake, it`s not my first language, so please 
don`t troll about this.

[android-developers] Re: MY FIRST APP IS NOT WORKING ON PHONE / EMULATOR

[bradleyclare]

You probably defined the DisplayMessageActivity outside the original 
application tag in the manifest file.  It should go inside the existing 
application tag.  I made that same mistake the first time going through it. 
 Good Luck.

[android-developers] Generating apk on Windows and OSX

[dbv]

We are in development mode and have:
Windows XP SP3 to generate apk_w.
Mac OSX 11.x. to generate apk_m.
Both apk_w and apk_m are identical but with different certificates -
an apk install with different certificate requires that previous apk
is uninstalled first instead of overwriting.
Min API 7 level.

apk_w installs on Nexus (Android 4) and HTC (Android 4) but, doesn't
install on Galaxy/II (Android 4) or Galaxy/I (Android 2.2).
apk_m installs on Nexus (Android 4), Galaxy/II (Android 4), Galaxy/I
(Android 2.2) and HTC (Android 4).
After apk_m installs successfully on Nexus (Android 4) and Galaxy/I
(Android 2.2), apk_w is re-installed on Nexus and Galaxy/I and this
time installs successfully.

This was repeated multiple times with the same results.  Has anyone
come across similar bizarre behavior with Windows XP or have a
possible answer?

[android-developers] File manager code help

[Turnipz]

Hey guys, below is my code for my program, it gives me a list of 
directories and it allows me to click through one directory, however if I 
try to click through to 2 folders deep it wont let me because of 
"if(K.getAbsoluteFile().isDirectory()==true)", and removing this gives me a 
crash.  Can anyone tell me why it wouldn't recognize "File K" as a 
directory the second click through in my browse class?

[android-developers] programmatically capture audio from a specific channel?

[CMaN]

I would like to capture the audio from a specific channel (eg. I have a 
3.5mm headset and a Bluetooth headset both connected to an android phone. 
Right now, it receives audio from both sources when I use "AudioSource.MIC" 
and I would like to capture an audio from a bluetooth headset only) is 
there anyway I can specify the audio channel? How can I programmatically 
capture audio from a specific channel on Android?

My device is the Nexus One, running Android 2.3.7, Bluetooth headset Jabra 
BT 2035

[android-developers] Dynamic table building - Set Weight of Seekbar so it fills space.

[Extremest]

I have extended a table row and add a checkbox and a seekbar to it. I
cannot set the seekbar's gravity in code to 1 so that it will fill the
rest of the row.  Instead it just stays there as a very small object.
I dynamically create each row object and add them to a tablelayout.
Please help if you can. If it needs to be done in xml that is fine as
long as the id's for each can still become dynamic when each row gets
built.

I need to create an app that will read a barcode continuously until it 
drains the battery to the point where the device shuts down. I will need to 
collect data of the barcode, the barcode type, the time duration it took to 
scan the barcode, as well as how long the battery lasted. 
I have never coded in Android before so I could use any help I can get. 
Thank you!

Re: [android-developers] new look for the android app developers website

[Mark Murphy]

Perhaps somebody has a complete mirror of the old one somewhere,
though I am not aware of any.

Bear in mind that a new statue appeared at the Googleplex, and today
is the first day of the Google I|O conference, meaning that we are
probably just a few hours from a new Android SDK release, whose docs
will only show up in the new site layout.

Re: [android-developers] How to get battery percentage

[Mark Murphy]

You will want an ACTION_BATTERY_CHANGED BroadcastReceiver. See
BatteryManager for the names of the broadcast Intent extras:
EXTRA_LEVEL and EXTRA_SCALE will combine to give you a percentage.

Sorry to say, but its not the perfect solution I need, coz I want
information to be saved/stored only when any application starts or closes,
(say browser app: started 1 time, closed 1 time), which should only be
updated on launch or termination of app. The updation should not happen
periodically, as it may create problem as well as may be called multiple
times on a single time execution of app.
Hope, you are getting my idea.

Yeah, I hear you.

Grey text on grey background? A body font with very dense letter spacing?
Headers with empty space before and after that looks excessive even on a
1200px tall monitor?


Here is a stylesheet tweak that makes the redesign usable for its primary
purpose - reading the docs.

Re: [android-developers] How to upload apk with new version, when previous key store is lost?

[Raghav Sood]

This isn't possible. You cannot sign two versions with different keys.
Neither can you recover a key from a signed apk. It is best to keep several
backups of your keys.

You'll have to upload a fresh app now.

You should not bother about record chunks. Devices (or the operating 
system) are supposed to handle them automatically. So all you do in your 
app is put the record payload into an NDEF record and the NDEF record into 
an NDEF message.

If a "remote device" splits the record into multiple chunks, the Android 
system should join the junks into full records before presenting them to 
the app. (Although, I have not thested if Android is capable of handling 
chunked records.)

Re: [android-developers] How can I open my app with power button?

[Fred Niggle]

The best way to achieve this would be making your app start at boot.
Without modifying the firmware of users phone's there would be no way to
having the power button do anything else aside from power the device up.

I hope that if i have missed something here then other will pitch in and
correct me.

Re: [android-developers] finding which application uses a port on the android device

[Fred Niggle]

I am unsure if i understand you question, it may be that programs
communicating with a server do not need to identify themselves to a server,
they merely send/receive data.

While some programs, such as browsers do identify themselves, this is not
always true.

I would suggest that you practice with a normal server setup, and once you
have a method that works you can begin to port that method for your app.

Fred

First of all, you are partly right: The embedded secure element can be 
enabled with the latest device firmware (or is usually enabled by default 
to allow Google Wallet to work). Second, you are certainly wrong with 
MIFARE 4K beeing a Type 4 NFC tag! MIFARE 4K (and so does MIFARE 1K) use a 
proprietary protocol that is not specified as part of the NFC Forum's NDEF 
tag specifications. Still, once the embedded secure element is enabled for 
card emulation the MIFARE 4K area is readable and writable with the default 
keys. So it could probably be used with *some* NFC devices as NFC tag. 
Remember, however, that not all NFC devices support MIFARE 1K/4K. Also, 
this only allows external access to the MIFARE area. Internal access, i.e. 
through an app on the same phone, is still not easily doable. (It can be

I certainly would not call this *full* card emulation. Especially as you 
cannot modify the card content from within the phone.

The question is too vague, we need much more information in order to be

e.g.
What environment is the game going to be played in, indoors or outdoors?
 
What surface types will you be mounting the tags on?
 
How much data do you need to encode onto the tags?
 
etc.

Re: [android-developers] Re: Help converting iPhone app to Android

[danskr]

The only problem is already having gone down the phonegap route, it's a 
little too late to learn a new system and rebuild from scratch. You live 
and learn though..

I was never expecting amazing performance, but its fairly simple app and 
its offered for free so I'm not massively concerned about the performance 
at the moment (although those links much appreciated - thanks TreKing!). 

My main concern is just getting it to work on OS 3 and over. On 2.3 it 
works, not great but acceptable for the moment. On anything higher it 
stalls at Waiting for HOME ('android.process.acore') to be launched...

Let me clarify you about my requirement.
I actually want to monitor all the apps stored in the device, and retrieve
their information (like how many times app is opened or closed. All that
process of maintaining the record will start, when I first time install my
app (which will show me details of other apps).

For this reason, I wanted that as soon as any device app (system's app as
well as user's apps), is launched or closed, the database should be updated
like ---
*App A started: 2 times and stopped 1 time total usage: 15 hrs, App B
started 3 times stopped: 3 times, total usage: 7 hrs*

And in my own application, I can retrieve that information.

I wish, my problem is somewhat clear to you.

NSR

You almost just want to grab the output of  "dumpsys usagestats" but that's 
restricted to apps with the android.system.DUMP permission installed in 
/system/app.  (I'm guessing that this level of data collection is not 
"evil" as Google has the DUMP permission in their proprietary Google 
Services Framework and Google Account Manager, but I'm not sure why it's 
discouraged for app developers but ok for google..)  I think the DUMP 
permission changes between Dangerous and SystemOrSignature depending on 
what Android version you are looking at so you might have to be 
pre-installed on the device to do it (root/build your own ROM.)

If you don't want to poll, you could try a blocking read on "logcat -s -v 
time ActivityManager" and parse for the start intents (but you'd still have 
to go look for application exit in the RunningAppInfo, but you could only 
do that on ActivityManager messages so you'd only be doing it when the 
ActivityManager is changing applications.)  You'd need the 
android.permission.READ_LOGS permission to do that.

Neither of these are SDK supported, and both cost you an extra process, but 
the logcat process is pretty light weight, and the dumpsys would only need 
to be run once at reporting time.  In theory the user would is alerted on 
application installation that you are requesting the dangerous permissions, 
so you might want to be clear about why you need them in your application 
description.  In practice the de

Re: [android-developers] Re: How to create a x509 certificate?

[Simon Trigona]

You can't create a certificate with the built in Bouncy Castle library.
Unfortunately, you can't include the Bouncy Castle JAR  in your android app
because of a naming conflict.

All hope is not lost. Find and use the Spongy Castle JAR. This is identical
to Bouncy Castle but with a different package name. You'll be able to
create your certificates with this library.

This doesn't have anything to do with Android.

[android-developers] Querying for system capabilities

[Simon Giddings]

In my activity I need to be able to query if the following services are 
available :

   - phone call
   - email
   - internet browsing

This is to ensure that I only provide these options when they exist on the 
device.
For example, phone calls are not normally available on a tablet.

Can this be done ?

[android-developers] Re: Not allowing me to install SDK as java jdk is not being recognized

[RichardC]

When you get to the screen where it tells you that it cannot detect the 
Java SDK try this:

   - click the [] button

This sometimes works to clear the problem.

That depends on what you mean. These are not "services" -- they are
applications. And, more importantly, they have activities which
represent the user interface.

So, if you want to know if, say, an ACTION_DIAL Intent on a tel: Uri
will work, create an Intent for it and call resolveActivity() on
PackageManager. If it returns null, you know that a startActivity()
call will fail on that same Intent.
