[android-developers] Re: alphabetic scrollview navigator

[Bob Kerns]

I didn't see a redirect bug -- but gmail failed to include the final
')' in the link, so the anchor survived, but failed.

So what is it with these redirects, anyway? It's always sending me to
some random locale -- fr one day, de today. Fortunately -- they're all
in English.

I'm using Chrome, on Windows 7.

[android-developers] Re: TabActivity with scroll

[priyanka]

Thanks very much for your ideas folks.

Hc - its a cool tabhost you've made! :) Thanks a lot, and I'm sure it
will be very useful for a requirement of always fitting in within the
screen. Unfortunately, my requirement is such that I do not want to
reduce the width of each tab as the number of tabs increases :(

Beth - thanks a lot for the suggestion..I'll try it out..it might give
a nice look.

In the meantime, I've made a tabhost of my own with a ScrollView such
that it scrolls when the tabs cover a width more than the page width.

Cheers,
Priyanka

In the meantime, I've made a tabhost as Mark suggested - such that the
fourth tag gives a list of the remaining functionalities, and the user
might go to them through this tab.
I had made a tabhost which used to scroll when number of tabs occupied
a width greater than the screen width, but then the look was not very
intuitive(we decided we don't want users to scroll in a tab) - hence
we discarded the idea of scrollable tabs.

Cheers,
Priyanka

[android-developers] Re: Vertex arrays vs. VBOs

[Lance Nanek]

Robert Green has mentioned VBOs being fast for his uses a couple times
on this list, I think. Might be worth searching those posts out.

Not actual usage, but I saw them mentioned in some docs recently. It's
for a newer version of OpenGL ES, but this ImgTec document recommends
VBOs, for example:
http://www.imgtec.com/factsheets/SDK/POWERVR%20SGX.OpenGL%20ES%202.0%20Application%20Development%20Recommendations.1.1f.External.pdf

ImgTec's PowerVR SGX design is in the Droid

Qualcomm also recommends VBOs:
http://www.brewconference.com/brew_2007/pdf/Prog-401_Dorbie_v05.pdf

Although that presentation is for BREW, not Android, and skips over
their MSM7200 design which is in the G1.

The differences in the documents are interesting. ImgTec recommends
interleaving all the data for a vertex together. Qualcomm recommends
tightly packed instead. ImgTec recommends always using an indexed
triangle list. Qualcomm recommends triangle strips, stitching them
together with degenerate triangles for screen aligned quads.

[android-developers] Re: Suspicious TCP RST packets while device is sleeping.

[Bob Kerns]

Well, I don't grok NAT enough to conclude that it's wrong. But I don't
see why they'd do it -- unless they're trying to minimize traffic.
Seems kinda trivial -- and likely more than offset by the later
attempted transmit.

I'm not sure what problem you're trying to solve. It can certainly
happen that one side thinks a connection is open while the other
thinks it's closed. The recipient sends a RST, the sender gets a
"connection reset" and life goes on.

Is it the delay in discovering the disconnect that's the issue?

Re: [android-developers] Re: Forcibly using 3G or CDMA network even though wi-fi is available.

[Anonymous Anonymous]

MMS cannot be sent over wi-fi.Carriers network is mandatory to send/recv.
The MMSC need to identify from/to the message coming going and it wont be
possible while using wi-fi.
So its required to switch to 3g or CDMA even if wi-fi is available.

[android-developers] Why are my SharedPreferences suddenly deleted, after I updated my game in the Market?

Hi!

Why are my SharedPreferences suddenly deleted, after I updated my game

Here is the logcat:

[android-developers] Cant find the solution for this GLSurfaceView error

[satish bhoyar]

Hi all,

I have a code for GLSurfaceView which runs fine with sdk 1.5. I am trying to
use it in the sdk 2.0 I am getting following error - >
"*Application called a GL11  Pointer method with an Indirect Buffer*"

This is the line at which the error is coming,
*gl.glVertexPointer(3, GL10.GL_FLOAT, 0, slicesBuffers[i]);

*Please anybody explains me why this error comes & how to solve it?

or any other  suggestion is also good for me.

Thanks,
SaT

[android-developers] How to get a remote logcat on error?

I want to solve them but I need a logcat. There is the application
"aLogcat" in the Market, which displays the logcat on the mobile, but
I need the logcat of my users without telling them to download this
app, because many people are lazy and won't do it. How can I get this
logcat? Is there maybe a library, which sends me the logcat on error?

[android-developers] Re: Cant find the solution for this GLSurfaceView error

[Lance Nanek]

The buffer needs to be direct so that it isn't moved around in memory.
You can do this by creating it using ByteBuffer.allocateDirect. You
can see examples in demos:

[android-developers] Re: Help needed with parsing some XML data !

[MobDev]

Actually this is the code for the second approach :

/* Create a URL we want to load some xml-data from. */
URL url = new URL("http://www.myserver.com/xmlstream";);

/* Get a SAXParser from the SAXPArserFactory. */
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();

 /* Get the XMLReader of the SAXParser we created. */
XMLReader xr = sp.getXMLReader();
 /* Create a new ContentHandler and apply it to the XML-Reader*/
ExampleHandler myExampleHandler = new ExampleHandler();
xr.setContentHandler(myExampleHandler);

/* Parse the xml-data from our URL. */
xr.parse(new InputSource(url.openStream()));
/* Parsing has finished. */

And the error I get is :
At line 40, column 23: not well-formed (invalid token)

which is around this XML line :


So where should I specifiy its an ISO-8859-1 ?
Also I have been debugging the app, but I actually cannot see the
stacktrace, could you please direct me on how to show it on NetBeans ?
Every time I try to look at the exception thrown I will see several
variables but StackTrace will be null...

[android-developers] Re: Bug? Invalidate causing unnecessary redraws.

It seems that adding a 1 pixel (1px) view stops this happening.

[android-developers] Re: reg AttributeSet

Figured out there is an internal implementation of XmlResourceParser.
It works for compiled resources only.

Are there any plans in the roadmap of coming up with an AttributeSet
implementation for non-compiled files as well ?

[android-developers] Re: Using WifiManager to connect to a network

[Neil]

I can't help with your protocol question, but the reason why
specifying the SSID isn't working is because it needs to be a quoted
value, e.g.

wifiConfig.SSID = "\"test\"";

[android-developers] Re: RssFeed Update

[raghavendra k]

Hi,

Have you used partial wake lock? I got the similar problem in my
app. I fixed it by using wake lock. Following is my code snippet. May
be this will help you.


PowerManager.WakeLock wl;
try {
PowerManager pm = (PowerManager) context

.getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, 
"Nyros");
if (wl != null)
wl.acquire();
//do your stuff here

} catch (Exception ex) {

} finally {
if (wl != null)
wl.release();

}

Thanks & Regards,
Raghavendra K.

[android-developers] Re: getting the serial number

[guich]

Hey, thanks

Worked fine on G2. This is the code i used:

#include "sys/system_properties.h"
  char buf[32];
  buf[0] = 0;
  __system_property_get("ro.serialno",buf);

Interestingly enough, i also tried this:

   char buf[2048];
   if ((in = open("/proc/cpuinfo", O_RDONLY)) < 0)
  debug("can't open"); // 2mb at least, or some litebase tests
will just skip over.
   else
  {
   if (read(in, buf, sizeof(buf)) < 4)
  debug("can't read");
   else
   close(in);

and it outputs:

can't read
Processor  : ARMv6-compatible processor rev 2 (v6l)
BogoMIPS   : 383.38
Features   : swp half thumb fastmult edsp java
CPU implementer: 0x41
CPU architecture: 6TEJ
CPU variant: 0x1
CPU part   : 0xb36
CPU revision   : 2

Hardware   : sapphire

The interesting thing is that Serial is 0!

[android-developers] Re: How to get a remote logcat on error?

[Martin]

Or is there another possibility to debug my game, while it is in the
market?
How can I intercept all the errors in my code to find out how I can
solve them?

If nobody has an answer to this, I have to put a
try {
...
} catch (Exception e) { /* send this exception and line number over
internet to me */ }
on EVERY line of code?

For example:


@Override
public void onCreate(Bundle savedInstanceState) {

try {
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
Global.screen_width = dm.widthPixels;
Global.screen_height = dm.heightPixels;
Global.screen_width_factor = 320/Global.screen_width;
Global.screen_height_factor = 480/Global.screen_height;
} catch (Exception e) { /* send exception - METRICS */ }
try {

super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags
(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN );
} catch (Exception e) { /* send exception - window */ }
try {


setContentView(R.layout.main);
} catch (Exception e) { /* send exception - contentview */ }
try {

//Sound starten
SharedPreferences prefs = getSharedPreferences("options", 0);
Global.bgmusic=prefs.getBoolean("music", true);
Global.soundeffects=prefs.getBoolean("soundeffects", true);
} catch (Exception e) { /* send exception - start sound */ }
try {


b_start = (Button) findViewById(R.id.b_start);
b_start.layout(120*Global.screen_width_factor,
55*Global.screen_height_factor,
(120+buttonwidth)*Global.screen_width_factor, 
(55+buttonheight)*
} catch (Exception e) { /* send exception - startbuttoncreated */ }


and so on

or is there a better solution?

Greetings, Martin

[android-developers] Re: VerifyError - how can I solve this error?

[Martin]

On my mobile, I do NOT have the VerifyError! This is strange. I just
get the Error-Messages from Flurry-Analytics from people, who
downloaded my game in the market, so I think that these error-messages
come from a specific Android OS?

What does it mean that some part of a class failed verification? Which
verification?

Martin

[android-developers] Re: Help needed with parsing some XML data !

[MobDev]

Btw I also have tried this instead :

 try {
URL url = new URL("http://www.myserver.com/xmlstream";);
URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream();
Xml.parse(is, Xml.Encoding.ISO_8859_1, new ExampleHandler
());
} catch (Exception e)
{
throw new RuntimeException(e);
}


This time it wont just crash but for example if I print the output
(through Log) I get

Found attribute : Ã…land eilanden
and
Found attribute : Albanië instead of Albanié

So any input on this ?

[android-developers] Re: Splitting connections?

[Bob Kerns]

Well, you' have to modify your routing tables. I see there's /system/
bin/route, and it worked to add a default gateway, running as root.
You WILL have to be root; if you haven't rooted your phone, you will
need to.

/system/bin/route seems to lack many of the normal features -- the
BusyBox one seems more complete.

Depending on your environment, your network administrators may not be
happy with you if you do this. In some scenarios, they might even be
justified -- but then you shouldn't have access with your phone in the
first place.

I'd be happy to hear there's a saner way to do this, but I don't think
there is. Usually, you'd just turn off WiFi, but that won't work if
you need both from the same app at the same time!

[android-developers] how to identify the views part of the current screen

[pradeep]

Hi All,

Can anyone give an idea how to identify the views part of the
active screen[i.e current running activity on the phone].

E.g after launching uiEditContactActivity,how can I identify the views
[ several fields, buttons etc]
part of that screen.

I am trying to modify monkey, such that for creating a contact, it
should launch Edit Contacts Activity and fill the respective views
[name, number etc].

Thanks,
Ganesh

[android-developers] Re: Help needed with parsing some XML data !

[Bob Kerns]

Well, you found one way to get the encoding in there. A few more:

InputSource.setEncoding("iso-8859-1")
new InputStreamReader(stream, "iso-8859-1");

I'd argue that it should have gotten it from the ? -- I'm a bit surprised it didn't. But it's
something I'd never rely on if I know the encoding.

Anyway, re: your problem below. It's probably working right, up to the
point of the log statement.

The log stream is probably taking those bytes, and then later they're
being interpreted as UTF-8. or it's taking the characters from the
string, and interpreting them as UTF-8 (via String.getBytes()) and
passing them off to a log stream that doesn't know about UTF-8.

Try logging to a file. Or better yet, create test cases, and verify
the correct operation of your code via test suite, rather than via log
statements.

But if you have any control or influence over the server -- fix the
problem there. ISO-8859-* should be of purely historical interest in
interpreting old documents. The first draft of ISO-10646 came out
nearly 20 years ago, and UTF-8 has been around for nearly 18 years.
The world is international. It's time to put a stake in the heart of
these national encodings.

[android-developers] GUI/CUI FTP Client

[Ryu]

If you like a file manager-type GUI with console based CUI terminal,
Runftp is what you want to have.

You can type and test any basic FTP commands in the terminal, and
viewing
through the files and directories in a two-pane tree-style graphical
navigation
at the same time.

Yes, exactly, I agree. When you set up an emulation there's too many
options, how do you really know if you are going to see the same as
you would on each device?

[android-developers] Re: Unable to set Camera Picture Size on Samsung Galaxy

[eni]

I believe it's a Samsung Galaxy problem, as it works on both G1 and
Hero. I'm setting PictureSize, but the change doesn't seem to be
registered by the device.

Creating a Bitmap from the full-size image unfortunately throws an
OutOfMemoryException, and I'm unfortunately unable to guarantee enough
free memory for manipulation of a 5mp image!

Re: [android-developers] Re: Using WifiManager to connect to a network

Neil,

Thanks for the catch on the SSID.  Actually, I find that I can only connect 
when I do not specify the SSID.  Documentation on wifi management is a little 
hard to come by.  I am learning the wifi packages and device/driver 
functionality through trial and error, logging,  and network monitoring.  I'll 
eventually get there.

[android-developers] Why setting TextView.Ellipsize as Marquee cause its sibling view in linearlayout redraw

[James Wang]

Hi
We are using TextView's Ellipsize function to scrolling text in it and
there many other controls in our window.
We noticed CPU would go up to 50% if text started scrolling. After
digging deeper, we found all controls in our layout kept drawing when
texts scrolling. We wonder why? And how to avoid all controls
redrawing?

Best Regards

James

I was wondering about your statement :

Our problem is that the whole system I am using is based on the ISO

[android-developers] VBO and DrawTex support

[Richard]

I know VBO's and DrawTex extensions are not a requirement for all
devices to have, but does anyone have a list of what devices don't
actually support them? I haven't actually come across any yet...

[android-developers] Canvas drawing

[Neilz]

Hi all.

When overiding onDraw() in my View, is it possible to say "Don't draw
anything new, just keep what was there the last time"?

In my app, I only want to draw when I get a sensor change. These
changes come intermittently. However the draw() routine is being
called continuously, many times per second, and is causing a lot of
overhead. I want to hold the last screen output until I have new
readings to pass in.

Is this possible?

[android-developers] Re: Canvas drawing

[schwiz]

your draw routine should only be called if you call invalidate on your
view or its parent view.

Isn't there anyone out there who can tell me not to pursue this with a

[android-developers] Re: Canvas drawing

[Neilz]

It is being called... between 5-10 times a second. I just set up a
routine to check. And I'm most definitely not calling invalidate() on
these occasions.

Has anyone notice that Android 2.1 (or may be even earlier) has
additional Network Type?  Namely:

ConnectivityManager.MOBILE_MMS 2
ConnectivityManager.MOBILE_SUPL 3
ConnectivityManager.MOBILE_DUN 4
ConnectivityManager.MOBILE_HIPRI 5

In addition to the original types in the document.
MOBILE 0
WIFI 1

Does anyone know what those new types corresponds to?

[android-developers] Re: Why are my SharedPreferences suddenly deleted, after I updated my game in the Market?

[JP]

There used to be an old old bug where shared preferences would
sporadically just disappear. Your post inspired me to do some research
and find out if that ever got fixed... En route I found this for you:

I believe you simply have to use InetAddress.getByName(String Host) ?
Like I did use InetAddress's getLocalHost() in resetConnection()
funcion in my local app? :

http://run.sh/repos/Runftp/src/sh/run/Runftp/FtpConsoleText.java

Anyway the Socket() automatically resolves the hostname when given.

[android-developers] loading files(images) from sdcard in webView

[Yaya]

Hi,
i am trying to load an html file which refers an image stored in the
sdcard. Actualy the html is provided by a local servlet. in the html,
i have this line "".
When i used that,  i had this error : " Not allowed to load local
resource: file://".

I find out that android does not allow this kind of things for
security reasons . So i searched  on Internet(see links at the ends)
and i saw that i need to create my own ContentProvider to handle the
way to access the local files. I did it by creating a
LocalContentProvider that extends ContentProvider and i overwrited the
method openFile(android.net.Uri uri, java.lang.String mode). Then i
modified the androidManifest to add the provider.

androidManifest:


LocalContentProvider (stored in com.myCompany.myPackageName):

public ParcelFileDescriptor openFile(Uri uri, String mode) throws
FileNotFoundException {
URI fileURI = URI.create( "file://" + uri.getPath() );
File file = new File( fileURI );
ParcelFileDescriptor parcel=null;
try {
parcel = ParcelFileDescriptor.open(file,
ParcelFileDescriptor.MODE_READ_ONLY);
} catch (FileNotFoundException e) {
Log.d(LOG_TAG,"Error finding: " + fileURI + "\n" + 
e.toString());
}
return parcel;
}


After theses modifications i tryed with  and i
had
"Failed to find provider info for com.myCompany.myPackageName"




here is my question:

How can i change the html to make it access the local files via the
contentProvider ?
What am i doing wrong ?


i' based on theses exemples:

http://blog.tourizo.com/2009/02/how-to-display-local-file-in-android.html
http://www.techjini.com/blog/2009/01/10/android-tip-1-contentprovider-accessing-local-file-system-from-webview-showing-image-in-webview-using-content/



i' am using Android 1.6 SDK, Release 1 on windows XP.

Thank you for your help and i am sorry for my very bad english.

Yaya.

[android-developers] Re: ANDROID_ID always null on devices

[Gregg Reno]

How about using the WIFI MAC address in cases where the ANDROID_ID is
null?  I believe it should be unique for each device:

WifiManager manager = (WifiManager) getSystemService
(Context.WIFI_SERVICE);
WifiInfo wifiInfo = manager.getConnectionInfo();
String MACAddress = wifiInfo.getMacAddress();

This seems to pull back a MAC address even if WIFI is turned off.

Re: [android-developers] Re: Writing files SDCard on Emulator

[Ace]

Mahendra/String,

Thank You for your reply on this. The problem was with the following code as
pointed correctly by you folks

String state = Environment.getExternalStorageState();
if(state != Environment.MEDIA_MOUNTED) {
Log.d("DEBUG", "The Card is Not Mounted " + state +"--");
throw new IOException ("SD Card is not Mounted. It is in " +
state);

After hardcoding the path as per the code below (pointed by Mahendra) I'm
able to write the file onto the SD Card and see the same in DDMS
/sdcard/somefilename

I think this problem is only with Emulator as mentioned in Emulator
Limitations in Android Docs->Tools->Emulator.

Further Questions
1. Would the code like Environment.getExternalStorageState.etc work when
using the actual device.
2. Would the path name like /sdcard be the same when connected to the actual
device.


Thanks & Best Regards
Acer

[android-developers] sticky client IP address?

[Vertifi]

Hello,

I have an app which performs some online functions to a web server
farm we operate using URLConnection.  I'm finding that the client IP
address of the phone seems to change after a fairly brief period of
inactivity.

For example, please see these timestamps and the corresponding client
IP addresses:

2010-02-03 09:46:47 / 32.152.30.98
2010-02-03 09:47:05 / 32.152.30.98
2010-02-03 09:57:21 / 32.152.218.197
2010-02-03 09:59:53 / 32.152.23.19

This is sitting in a stationary location (on an AT&T EDGE network) in
my office.  Is there some reason for this behavior?

Any advice would be greatly appreciated

Regards,
Chris @ Vertifi

[android-developers] Re: VerifyError - how can I solve this error?

[Streets Of Boston]

To help you, you need to post the log (form LogCat) showing the stack-
trace of the VerifyError.

As an example, VerifyErrors can occur when you load a class compiled
in Android 1.6 and using/calling 1.6 specific fields/methods and then
the class is run in a Android 1.5 environment.

I had one such (coding) error in my app, which should run on 1.5 (and
up)
e.g. i used the BitmapFactory.Options.inDensity field, which works
fine on 1.6 (or higher) phones.

However, when i ran my app on a 1.5 phone, i got a VerifyError because
of the use of use of 'inDensity' in my app's class.

Do not hardcode /sdcard. Use Environment.getExternalStoragePath() to get
the path to the SD card.

No. Some devices have their SD card under different paths. Use
Environment.getExternalStoragePath() to get the path to the SD card.

1. When I use the above method, I end up with the problem of device not
mounted, how can I overcome this on an Emulator.
2. On the actual device, how can I determine the path? Can I use adb shell
to navigate through the device?

Thank You again for your patience and help.

That method works perfectly fine on the emulator. The problems you have
reported in this thread are with a different method
(getExternalStorageState()). Also:

-- Never use + to concatenate paths together. Use the proper constructors
on the File class for that.

-- You do not need to call getAbsolutePath() on the result of
Environment.getExternalStoragePath().

> 2. On the actual device, how can I determine the path? Can I use adb shell

Your code should use Environment.getExternalStoragePath(). You as a
developer can use adb shell or DDMS' File Explorer to poke around and
deduce the path.

Re: [android-developers] Re: DNS Query

[Lewske Wada]

You probably are not basically able to change it to your own server.
Chances are you can connect to your internal WiFi network
and get the automatic DNS settings from dhcpd or whatever.
I can dynamically connect through my own rooter (Linux) and pass
that beyond to the internet by IP masquerading.

Re: [android-developers] AlertDialog in Android 1.5 and 2.0 / 2.0.1

[TreKing]

I've never had an issue with AlertDialogs in the emulator under any version.
Post the code you're using, you're probably just doing something wrong.

Re: [android-developers] Re: Help needed with parsing some XML data !

[Frank Weiss]

"Found attribute : Albanië instead of Albanié"

This suggests you are displaying UTF-8 text (which is was logcat does) as
Latin-1. To wit: ë = 0xC3 0xAB which are UTF-8 for Latin1 0xEB. However, é
is 0xEB, not 0xAB, so there's something else afoot.

Also note that when you see the rectangle with the ? in it, most likely
means you are trying to read a Latin-1 encoding as UTF-8. For example, 0xEB
by itself is invalid UTF-8. It would require two additional bytes each with
the top two bits of 10.

But good progress, bring on the data to analyze this problem. It would help
if you posted the URL to the XML

[android-developers] Re: How to get a remote logcat on error?

[Streets Of Boston]

This is not necessary, to catch every line of code.

Register an uncaught-exception-handler
(Thread.setDefaultUncaughtExceptionHandler). Before you set it, get
the current one. You may need to call it from your own uncaught-
exception-handler.

In this handler, print out the stack-trace (and some other info such
as OS-version, phone model, make, etc) to a file (on phone-memory or
sd-card)

These above steps are the bare basics.

In my app, I added a Service and an Activity, both running in a
different process than my app whose stack-traces i'm logging. If they
would run in the same process, it woudn't work (calling a Service and
Activity from a dying process).

The uncaught-exception-handling code binds to the Service
(initialization) and upon a stack-trace dump, after having generated
the file, it does a Service-request:

The Service starts the Activity that just shows a dialog asking the
using to submit an error report or not. If the user answers 'Yes',
then the Activity will read the file with the stack-trace info and
send it to a web-server (Http). The web-server gets this request,
generates an e-mail from it that is then sent to my inbox.

When the uncaught-exception-handler calls the service, it just kills
and extis the process. If the handler could not bind to the Service or
the Service-request failed, it calls the original default uncaught-
exception-handler that then shows the common 'Force Close' dialog.

This has been working well for me and found a few bugs here and
there :)

[android-developers] Re: Android 2.0.1 SocketTimeoutException received with FTP Data channel

[mericksonj]

The TCP port is entered correctly as 2121 when I connect to FTP, the
FTP cpntrol session is started properly according to the server logs.

I am not using SFTP since I have disabled the sub-system on my SSH
server.

I am trying to use SSH TCP forwarding alone to establish and maintain
the ftp session sice most FTP clients won't support 1024 bit RSA key
authentication.

I am considering FTPS, but I'm not sure I want to open up another port
to the internet.  The SSH service is the only one I currently allow
through the firewall.

Can you tell me more about the Java error message I'm getting? or
maybe if there are any android native FTP apps I can use?

Thanks!

[android-developers] Re: How to get a remote logcat on error?

[Emmanuel]

Note that I made a blog entry to explain how I made a crash reporter
using email on my blog, there :
http://androidblogger.blogspot.com/2009/12/how-to-improve-your-application-crash.html

It's a very effective way to catch the bugs, and to find how they
happen.

The fact that it is send by mail ( so the user should accept to send
it ) makes it really easy to do, you don't need to have a web site to
handle them, but most of the users won't send it. In my view, if
nobody sent me an crash report, I take it for granted there is no
common bug. If a bug is really common and happens often, it will be
sent !

Hope it helps,

Emmanuel

Ps : By the way, I don't fully understand why Flurry doesn't provide
the full call stack. They are so close, and they have done most of the
work to have a super useful tool, and they just stop one inch before
it... Strange... ( but it makes me feel good to have develop my own
crash reporter )

[android-developers] Vertical scrollview disappears on vertical and horizontal scrollview scheme

[David Arm]

Hi! I´m just trying to have both vertical and horizontal scrollviews
but the vertical one disappears just 1 second after the app launch and
I cant scroll down on my results.

Here are the codes:


XML:


http://schemas.android.com/apk/res/android";
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical" >

 http://schemas.android.com/apk/
res/android"
android:id="@+id/HorizontalScrollView"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

http://schemas.android.com/apk/res/
android"
android:id="@+id/DisplayResults"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>

[android-developers] Re: Android 2.0.1 SocketTimeoutException received with FTP Data channel

[mericksonj]

Ryu,

Sorry, forgot to address your iptables question.

I am not using iptables on either my emulator or Droid.  My firewall
only needs the one SSH port open in order to connect, and then with
the port forwarding through SSH additional firewall ports are
uneccessary.  I am not running a firewall/packet filter on the server.


I am currently using it regularly to access my HTTP server and view
the MRTG graphs and even telnet to various other devices inside my
internal network.

This works just fine on the Droid, and I am very impressed with my
android experience so far, I just can't get an FTP- Data session to
connect without this timeout error.

Thanks again!
--James

[android-developers] Re: DNS Query

[Bob Kerns]

Then you are doing something VERY strange.

DNS is a service provided to hosts (systems, i.e. your phone) by "the
network". It is not something that is under the control of the
application. Generally, a DHCP server (or the wireless carrier) will
supply you with your IP address, default router, DNS servers, and
other network configuration when you connect. It's a property of your
NETWORK environment.

Of course, applications are free to use IP addresses, and to obtain
them however they choose -- including implementing a DNS client
themselves. This, of course, raises the question -- how do you locate
your "special" DNS server -- and why is it special? Is it even
reachable in a particular environment? To prevent DNS spoofing
attacks, some network administrators may block external DNS requests,
and force you to go through their DNS servers.

Generally speaking, ANY DNS server should be able to resolve ANY
public DNS entry. And ONLY your local one that your network would tell
you about, would be able to tell you about special, local, DNS
entries.

About the only use I can see for such a scheme would be to contact a
botnet controller. Or, more likely, to work around a mis-configured
local network -- perhaps due to a poorly set-up VPN.

But in any event, an application should NOT try to hijack the entire
system's DNS resolution by hacking *hosts/**resolv**.**conf. This is
not "playing nice with others". There's a reason -- many reasons --
these files require root access.

[android-developers] Is passing AMR_NB into AudioTrack and AudioRecord valid?

[draf...@gmail.com]

I currently use AudioTrack and AudioRecord to create a looping sound
program and I was using raw PCM audio but I want to use AMR_NB audio
so I set up the code as follows

arec = new AudioRecord(MediaRecorder.AudioSource.MIC,
   11025,

AudioFormat.CHANNEL_CONFIGURATION_MONO,

MediaRecorder.AudioEncoder.AMR_NB,
   buffersize);
atrack = new AudioTrack(AudioManager.STREAM_VOICE_CALL,
   11025,

AudioFormat.CHANNEL_CONFIGURATION_MONO,

MediaRecorder.AudioEncoder.AMR_NB,
   buffersize,

AudioTrack.MODE_STREAM);

The above code works fine but is passing
MediaRecorder.AudioEncoder.AMR_NB in as the Audio Format valid or is
it working but actually not being encoded as AMR_NB?

I didn't mean that to be harsh, BTW. Knowing that an approach is out

information you can get, as a beginner, since it narrows the focus of
what you have to learn, a lot!

[android-developers] Educational Resources

[Bob Kerns]

We have a lot of questions here of a fairly basic, non-Android-
specific nature.

I think it would be helpful to compile a list of resources on various
topics, that we could refer people to (and try to get them to look at
before asking here  -- yeah, I know...)

Areas I see:

* TCP/IP and networking
* Cellular communications (I could use some of these, I bet)
* XML processing (XML itself, and the API's: DOM, SAX, XMLPull)
* Java

Done right, referring people to such a listing would be far more
useful to them than answering their immediate question. (I'm not
saying, don't answer -- but teach them to fish out their own answers!)

Of course, http://google.com would be right at the top of the list.
But a lot of time beginners don't realize how much information is
available to them -- or they're overwhelmed by the amount of
information available at the wrong level for them, and no way to judge
quality.

Except for cellular comm (where I have the opposite problem), I've
been around this stuff too long to have any reasonable resource
suggestions. I'd send you to the standards documents... :)

Can people help out with suggestions? Can Google people give them some
visibility on the list?

[android-developers] Re: TableLayout, Rotating

[Edward Falk]

I don't think the Android API lets you do what you want.  I wound up
writing my own "gridbox" layout widget which I use in several of my
apps.  It's similar to the old Java "gridbag" layout and HTML tables.
It does everything I need.  Unfortunately, it's not generic enough for
me to publish yet.

Well I don't know if you need two ports for FTP tunneled through
SSH, but seems like you could not create a data connection for FTP
over SSH.

I recommend FTPS as it runs on usual FTP ports (21 for connection
and some other for data channel) and is programmed in a secure
and established manner using standard SSL package.

I've developed an FTP client implementation using FTPS called Runftp
and should be downloaded in Market. (Searched by "Runftp" maybe)

[android-developers] Re: Coloring Default Buttons - color filter only on unfocused state

[RLo]

I see a similar solution on stackoverflow:
http://stackoverflow.com/questions/2065430/fixed-android-detecting-focus-pressed-color/2189757#2189757

but I have some concerns with that solution, mainly what if the OS
changes the graphic of the default button?  Since the normal unfocused/
unpressed graphic is now hardcoded into the app, it would break the
flow.

Maybe can someone comment on whether it would be good or bad practice
to hardcode the default graphic into the app?  What are the chances of
the OS completely changing the graphic?

Thanks!

It also has SFTP capability to some extent, but actually
depends on a third-party library (Jsch) and I suspect the
performance is not so good.  I'm talking about Runftp.

[android-developers] Re: Help needed with parsing some XML data !

[Bob Kerns]

Yeah, that's not what I mean by a test case.

See http://junit.org as a starting point.
(The Android SDK includes some limited version of JUnit I don't
recognize. It's adequate for this purpose, but the full, modern
version is better. For non-device testing, you're not restricted to
the supplied one.)

Basically, a test case is code that you can run to *automatically*
test some specific aspect of a system. In this case, checking against
a known set of XML (so it doesn't change), looking for the known
desired result, and reporting failures (expected conditions not
matching) and errors (unexpected exceptions thrown).

This removes the variables from the equation. You're not depending on
how things display, either in the UI nor in the log stream and
windows. You're not dependent on a human to notice a problem.

An best of all, you can automate it to always run when you build, so
if you break later, you'll find out right away, while you know what
you changed. And you can make changes freely, with the security of
knowing that you won't have to go through some long test/debug cycle.

I didn't answer your question about getting a stacktrace earlier,
because you said "NetBeans". I'm old enough to remember when NetBeans
was the hot new thing -- but too old to remember how to do anything
with it. Try using Eclipse and the ADK. It will show you the stack
trace in the same way it shows any other stack trace, as if you were
debugging locally. (I would expect NetBeans to, as well).

Or you can catch the exception, and use exception.printStackTrace() to
get it into the log (I'm surprised it's not already there).

This isn't really an Android problem, and it's not necessary to debug
it there. If you write your failing test cases, you can debug them on
your desktop computer, get them working, and you should be set to go
on the device.

Another thing to realize is that not all character values you can come
up with, are legal XML content. They *MUST* be valid printing Unicode
characters. No random control characters -- for example, ISO-8859-1
byte values 0-31 (decimal). This will ALWAYS fail -- it is NOT well-
formed XML. If that's the cause of your exceptions, your two choices
would be to fix it on the server (probably by encoding this binary
data) or to preprocess the fake-XML into real XML before you feed it
to the XML parser.

[android-developers] Re: Wakelock and phone restarts

[nikhil]

I dont have any issues with wifi after holding on to wakelock...but
yeah
when I try to forward calls the phone starts rebooting itself ...I
have to kill the service to stop it from rebooting again and again...
I have no clue why that happens..

Re: [android-developers] Re: Suspicious TCP RST packets while device is sleeping.

[Dan Sherman]

> Is it the delay in discovering the disconnect that's the issue?

Exactly...

The connection stays open to accept data from the server.  There are
definitely points in time when this wouldn't happen for a few minutes, and
if the connection dropped, that wouldn't be a problem if the client noticed
the disconnect immediately (it would just reconnect, and start waiting
again).  However, when the device sleeps, it doesn't see the disconnect
until it wakes up (possibly hours later)...

After a bit more research, it looks like if the client holds a wake lock
infinitely (just for testing), it gets the reset packet immediately when the
connection is killed, and re-connects immediately.  However, if the device
doesn't hold the lock, and goes to sleep, the reset packet is dropped
somewhere...

Anyone on the dev team able to explain that functionality
(intended/unintended/workaround?)

[android-developers] Re: Android 2.0.1 SocketTimeoutException received with FTP Data channel

[Bob Kerns]

You're reinventing the wheel here, back before they invented circles.

SFTP uses the same port as SSH (22 is the standard, but you can
substitute if you want to throw off port-scanners) -- you would not be
opening another port.

FTP is *extremely* problematic in the modern world. Originally, it
required that the SERVER open a port back to the CLIENT.

This almost always fails, these days, due to NAT, firewalls, etc. But
it is still the default in many clients. Even if you managed to make
it work, it would be highly insecure -- your data would NOT be going
through your secure channel, and you must open up ports on the client!

You'd have to use so-called "passive" FTP. You may even find clients
that don't implement it.

You're certainly going to be plagued with client differences. You're
certainly doing kinda-a-the-same-thing, but with a lot more
complexity, security issues, and problems.

Really -- if you have control over the server side, DO NOT implement
FTP.

[android-developers] Re: Android 2.0.1 SocketTimeoutException received with FTP Data channel

[Bob Kerns]

This is the standard result when trying to do active FTP and the
server cannot connect to the random port the client is listening on.

Yes, in standard FTP, the client must act as a server.

[android-developers] bind to a remore service

[dane131]

Hallo,

i have made an application that is consisted of an activity and a
service.The service has an interface (created by an aidl file)
including methods implemented in the service.My activity binds to the
service and calls some methods of the service.All good till now.My
problem is when i want to bind to a service that belongs to a
different package from my activity.My activity doesn't have visibility
of the remote interface and i cannot import it :

public class Client extends Activity {
/** Called when the activity is first created. */
IGps mservice=null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i=new Intent();
i.setComponent(new ComponentName("aexp.share.sharedapp3",
"aexp.share.sharedapp3.Service_impl"));
bindService(i, conn, Context.BIND_AUTO_CREATE);

}

ServiceConnection conn=new ServiceConnection() {

@Override
public void onServiceDisconnected(ComponentName name) {
Log.e("TAG","DISCONNECTED");

}

@Override
public void onServiceConnected(ComponentName name, IBinder 
service)
{

mservice=IGps.Stub.asInterface(service);
try
{
double a=mservice.getLat();
String a_str=Double.toString(a);
Log.e("TAG",a_str);
}
catch(RemoteException e)
{

}

}
};
}

Here i cannot see the IGps interface,Am i doing something wrong?
