I see that /data/app directory have information about date and time of
installed applications. But the bad news is that this directory is not
accesible through code. Anyone knows how I can get this information or
how I can access to this directory (/data/app/)?

[android-developers] When Activity is closed, its fields is not release, how to resolve this issue.

2010-05-20 Thread Jiang

In the followingscenario, the fields of 
Activity is not released when the Activity is closed with calling finish().
Class MyClass
{
}

public MyActivity extends Activity
{
    private MyClass obj;

    public void onCreate(xxx)
    {
        
        obj = new MyClass();
    }
}

when Activity is closed, the field 'obj' is not released. Certainly, we can add 
statement obj = null in onDestroy() to release it explicitly, but I'm curious 
that other fields of Activity is not released, is there memory leak?

I tried following test: 
1, Start Activity A
2, Start Activity B from A with calling startActivity
3, Close Activity B with calling finish();
4, Start Activity B in method onResume() of Activity A
When B is started about 2000 times, Android system report out of memory, it 
seems that memory leaks during the processes, how to resolve this issue?


Thanks very much.

[android-developers] Problem with light sensor

2010-05-20 Thread qvark

Hi there, I'm having some troubles with the light sensor on the Nexus
One.

AFAIK, the proper way to read the measures of a sensor is registering
a SensorListener through the SensorManager and then wait for the
readings on the onSensorChanged method.

My main problem is that the light sensor don't seem very accurate (the
readings jump a lot) and I don't get the first reading until the
lighting conditions change. I have to change the phone orientation, go
outdoors or hide the sensor with my fingers or otherwise I don't
receive any value. Is there any way to increase the accuracy or, even
more important,  to force an initial reading?

BTW, I have tried with SensorManager.SENSOR_DELAY_FASTEST but I
haven't noticed any change.

Thanks,

Jose Luis.

 implementations of the same interface.

 Now concerning your example, beta vs. non-beta, personally, I would
 not dream of making this distinction by using conditional compilation.
 Rather, this is a natural task for revision control: once the Beta has
 been released, that code must be checked in/committed to a definite
 revision in the depository, so that you can revert to it at any time.

 OTOH, using the computer's camera as the emulator's camera sounds like

I have been able to find the code. It was an example part of the SDK.
It specified on how to add the controls. Removal of controls are to be

 Yes this is annoying.

  - Add support to conditional compilation #IF,#ELSE,#ENDIF (I wan't to
  have 2 versions in the same proyect ... beta and non beta, free and
  paid, etc.)

 Free and paid apps shouldn't be done by a preprocessor for several
 reasons: You want to change the content of XML file. an XML
 pre-processor is going to be harder. Also you probably won't have the
 same files at all and a pre-processor won't really let you
 exclude/include whole files.

 We will introduce a new build mechanism that will allow you to easily
 share code and resources across 2+ application projects that will be
 much better at handling this case.

 As for the beta vs. final version, yeah, as someone else said, this
 makes no sense.

True. I didn't think about the XML. The reasons I need more time and
reading to understand.

  - Add support to add custom views to viewlist in IDE

 We're working on a new layout editor that will allow that and more.
Great.

  - Is there any way to add voice recognition? It is a feature that I
  would love to have to experiment with, but I can't since I don't have
  an Android mobile yet. I would REALLY love to have it.

 I think voice recognition isgooglespecific and requiresgoogle
 components that are not (and won't ever be) on the SDK system image.

  - Add support to C/C++ by adapting the eclipse or using another IDE. I
  feel guilty for wasting so many resources by using an intermediate
  code. I would not like to have a 1GHz processor and use it as if it
  where a 100MHz. And yes, leakage memory problems in C, C++ ... it is a
  problem, but it is worth the effort, and having in count how much code
  there is for C/C++

 Yes, better integrating the NDK into the SDK, and into the Eclipse
 plug-in is one of our goals.
great!

  - I would be nice that I could use the camera of my Computer in the
  emulator :)

 yes, it would be nice, wouldn't it?

Android offers two location services:

GPS  Network (mobile cell).

The developer can choose to register to receive location updates for
one or both of these.
You have raised a question I was wondering about though - does the
network location use WiFi to increase accuraccy? I have noticed I
sometimes get pretty good accuraccies (~75m) from network location.

[android-developers] Re: How to find memory leak?

2010-05-20 Thread pacoder

I've been using Eclipse MAT (http://www.eclipse.org/mat/) to look at
heap dumps. My phone isn't rooted so I run my app in the emulator then
use adb to do a kill -10 which forces a heap dump. I then do an adb
pull to grab the file (your logcat will give you the name of the heap
dump output file when it runs). Then I use the android hprof-conv tool
to convert the heap dump to one that MAT can read. Then just open it
up in MAT and you can look around through the dump. It will also
suggest leak candidates to you, it's a nice tool. Also, you will need
to grant write permissions to the output directory in your emulator. I
just go do a chmod 777 /user/data.

Re: [android-developers] When Activity is closed, its fields is not release, how to resolve this issue.


 In the following  scenario, the fields of

 when the Activity is closed with calling finish().
 Class MyClass
 {
 }

 public MyActivity extends Activity
 {
     private MyClass obj;

     public void onCreate(xxx)

 }

 when Activity is closed, the field 'obj' is not released.

I am going to assume that by not released, you mean not garbage
collected.

 Certainly, we
 can add statement obj = null in onDestroy() to release it explicitly,
 but I'm curious that other fields of Activity is not released, is there
 memory leak?

If something in your code is keeping your instance of MyActivity in memory
-- such as holding onto an instance of it or something referring to it in
a static context -- then you will have a memory leak.

 I tried following test:
 1, Start Activity A
 2, Start Activity B from A with calling startActivity
 3, Close Activity B with calling finish();
 4, Start Activity B in method onResume() of Activity A
 When B is started about 2000 times, Android system report out of memory,
 it seems that memory leaks during the processes, how to resolve this
 issue?

You are creating an infinite loop. Activity A be called with onResume() as
part of Activity B finishing, so you are restarting Activity B right away.
Do not create an infinite loop, and you will not run out of memory.

There are tools in Android to diagnose true memory leaks, such as the
Allocation Tracker and VM Heap in DDMS, or the dump HPROF file button in
DDMS in Android 2.x. Those will help you track down your memory leak.

[android-developers] Re: How to find memory leak?

2010-05-20 Thread Mathias Lin

Yourkit, http://yourkit.com/overview/index.jsp, is another profiler
tool that could be used.

In sdk2.1, you can also do it on a non-rooted device - you can create
a hprov from within the app and write it to sdcard.

Debug.dumpHprofData(/sdcard/myapp.hprov);

At least in v2.1, possible that this wasn't availabe in 1.x sdk.

pull to grab the file (your logcat will give you the name of the heap
dump output file when it runs). Then I use the android hprof-conv tool
to convert the heap dump to one that MAT can read. Then just open it
up in MAT and you can look around through the dump. It will also
suggest leak candidates to you, it's a nice tool. Also, you will need
to grant write permissions to the output directory in your emulator. I
just go do a chmod 777 /user/data.

[android-developers] Re: Application Crash Reporting made easy - needs testers

2010-05-20 Thread Kevin Gaudin

Thanks Tobias for using the lib !

All the sources are available on GoogleCode's SVN:
http://code.google.com/p/acra/source/checkout.

The main help we need now is developers to test the v2 stability with
its different notification modes and on different android hardware/
versions so that we can go out of the testing phase ;-).

I'm also waiting for details about the official reporting which
should be announced today at Google I/O. This might lead to some
adaptation in the code of ACRA depending on the availability of this
new reporting across android versions.

Though, the acra-2.0.0-test version is already clean enough to coexist
with the new reporting feature which is activated on my Nexus One
since yesterday... the behaviour I implemented is to disable the
default Force Close dialog when ACRA is configured with Toast or
Status bar notification mode. This prevents the user from beeing
offered several error reporting systems.

[android-developers] how browser decides html size on 2.1

2010-05-20 Thread James Wang

We have one html page whose backgroud is an image(1024px*600px) with
no-repeat.
We displayed it in Browser rightly on 1.6 HVGA(160) and WVGA(240)
emulator and scrollbar displaed on both sides.
But we got different result when testing on 2.1 HVGA(160) and
WVGA(240) emulator.
On 2.1 HVGA（160）, the background image is scaled smaller and we saw
large wide margin on the right.
On 2.1WVGA (240), There are two margins on right and bottom sides.
There is no scrollbar displayed on 2.1. And we put few small element
in our html page.

Is this Browser's bug?

[android-developers] Issue with WifiManager.calculateSignalLevel(RSSI, 5)

2010-05-20 Thread draf...@gmail.com

I am trying to use the Wifimanager to calculate the Signal Level of
the access points found during a scan.

I am using the following method:

http://developer.android.com/intl/de/reference/android/net/wifi/WifiManager.html#calculateSignalLevel%28int,%20int%29

But it appears to always return the same int no matter what the RSSI
level is.

Here is my code:

---

public int calculateQoS(int aRSSI){

signalLevel = WifiManager.calculateSignalLevel(RSSI, 5);

return signalLevel;

}


---


public void testCalculateQoS(){

Log.d(signal, signal = : 
+ connMonitor.calculateQoS(-44)
+   + connMonitor.calculateQoS(-80)
+   + connMonitor.calculateQoS(-120)
+   + connMonitor.calculateQoS(-20));

}

The logging outputs 1 for all the test cases for calculateQoS(int).

Am I missing something simple here? Why is the SignalLevel always 1?

[android-developers] Screen lock problem in SurfaceView

2010-05-20 Thread Eong

Hi,
   I need some help on SurfaceView for games. I use a SurfaceView in
my game and set a render for it. In the render I use some native call
from my native lib to draw the screen using opengl. This game uses
landscape mode and I lock the mode in my manifest.
   But ifI press powerbutton on my phone when I was in the game, the
phone will shut off the screen and get into the locked mode. So I
active it again, the screen will be back in portrait mode and locked.
If I press menu to unlock, only part of the screen will be rendered,
and the other part is dark.
   This happenes when I was testing on G2, but G1 seems to be working
fine.
   If anyone has idea about this?

Thank you.

[android-developers] Re: Avoid restarting background threads on orientation change

2010-05-20 Thread Jeff

Ok, I believe I have made a little progress on this. It looks like I
can use onRetainNonConfigurationInstance() to save an instance of my
thread objects and then call getLastNonConfigurationInstance() to get
them back when the Activity is restarted.

This leads me to a new questionwhen do I actually destroy the
threads then? Part of me is wondering if I even need to bother
destroying the threads - won't the OS do that automatically when it
needs to? One of the threads has an open database connection. I
imagine that should be handled more gracefully. The question is when
should I do this?

When an Activity starts, there is a way for you to tell if you have
saved state. When the Activity ends, I wish there was some reliable
way to determine whether the Activity is going to restart right away
or if its being destroyed for good.

Perhaps I am overlooking a fundamental aspect of the Activity
lifecycle in relation to background threads.

Any advice would be greatly appreciated.

 What is the preferred way of avoiding the shutdown of my background

 onSaveInstanceState and then not destroy my threads if this flag is
 set. Is this a valid approach or is there a more standard framework
 approach that I am overlooking?

Re: [android-developers] Re: Avoid restarting background threads on orientation change

 This leads me to a new questionwhen do I actually destroy the

As soon as their work is done. All else being equal, choose a model where
you do not keep your own threads hanging out forever (e.g., use AsyncTask
rather than forking your own threads).

 Part of me is wondering if I even need to bother
 destroying the threads - won't the OS do that automatically when it
 needs to?

No, it will not, except by terminating the process, which may not happen
for quite some time after your activity is destroyed. This yet another
reason to use AsyncTask rather than forking your own threads -- threads
*Android* forks *Android* is responsible to clean up.

Moreover, please bear in mind that your activity may be in a stopped state
for an extended period of time (a.k.a., days). Your goal, while stopped,
should be to avoid doing anything much. This is yet another reason to
design your application to avoid forking your own threads that hang around
indefinitely, but rather do your background work in short discrete chunks
in AsyncTasks.

 One of the threads has an open database connection. I
 imagine that should be handled more gracefully. The question is when
 should I do this?

As soon as your work is done.

 When an Activity starts, there is a way for you to tell if you have

In your case, if getLastNonConfigurationInstance() is not null, you have
saved state, in the form of the object returned from
getLastNonConfigurationInstance().

Re: [android-developers] Re: Avoid restarting background threads on orientation change

2010-05-20 Thread Jeff Thorn

As always, thanks Mark!

I definitely see your point - its better to do short chunks of work in an
AsyncTask than creating long running background threads.

My app makes a lot of http requests. After the download is complete, it
updates a database. I thought it would be better to create a single
background thread that does this work and then notifies the UI when its
finished. I thought this would be more efficient than opening a network
connection, opening the database, doing work, closing the database, etc.
each and every time. I suppose I could open the database in the main
Activity thread and close that in onDestroy and pass it to the AsyncTask
each time.

[android-developers] Re: How to force Activity to call finalize()?

2010-05-20 Thread Streets Of Boston

Don't rely on finalize() being called (at an even somewhat predictable
time).

Finalize is called by the garbage collector of every java Object. It
may be quite a while before finalize is called by the garbage
collector. Instead, implement the onDestroy.

[android-developers] Re: Functional testing multiple activities (ActivityInstrumentationTestCase2)

 Hi,

 I'm trying to write some functional unit-tests that involve multiple
 activities (end-to-end testing).
 I have great trouble to write stable tests, especially when
 ActivityMonitors are involved.

 When my root-activity starts another activity, i try to use
 ActivityMonitors to check if the other activity has started. I use the
 activityMonitor.waitForActivityWithTimeout(timeout) (where
 activityMonitor is a non-blocking activity monitor for
 'AnotherActivity.class.getName()'). The problem is that
 waitForActivityWithTimeout sometimes works fine and returns the
 instance of AnotherActivity. However, often it just waits for
 'timeout' milliseconds and returns null and my root-activity is still
 considered the 'active' or 'last' activity. But when i check the
 screen, the AnotherActivity has been showing!

 Should i be using ActivityInstrumentationTestCase2? Or some other test-
 case class?
 How does one write reliable, non-fragile, functional unit-tests
 spanning multiple activities?

 Thank you!

Re: [android-developers] Re: Avoid restarting background threads on orientation change

 My app makes a lot of http requests. After the download is complete, it
 updates a database. I thought it would be better to create a single
 background thread that does this work and then notifies the UI when its
 finished. I thought this would be more efficient than opening a network
 connection, opening the database, doing work, closing the database, etc.
 each and every time.

IMHO, that's a premature optimization. Moreover, it does not preclude the
use of AsyncTask:

 I suppose I could open the database in the main
 Activity thread and close that in onDestroy and pass it to the AsyncTask
 each time.

Likewise, if you use an HttpClient with a ThreadSafeConnectionManager, you
can do the same thing for your HTTP connections:

http://svn.apache.org/repos/asf/httpcomponents/httpclient/tags/4.0.1/httpclient/src/examples/org/apache/http/examples/client/ClientMultiThreadedExecution.java

(or http://bit.ly/cKW7ws if that URL is too long)

[android-developers] App causing crash/reboot cycle

2010-05-20 Thread kec6227

So I have 2 reports now of my app causing a crash/reboot cycle the
user can't always break from. I cannot reproduce this on my phone, and
I am wondering what might be causing something like this? Would
running out of memory or something cause this? Because I can't
reproduce it, I can't look at the logs or anything.

Has anyone experiences anything similar? For reference, my app runs a
foreground service which utilizes the AlarmManager. It starts
automatically on boot_completed (which is probably why the cycle
happens). One of the users who reported this, said it only happened
when they plugged their phone into a PC.

So, anyone have any ideas?

Thanks

What I don't understand is why people who want this don't just
use /usr/bin/cpp in their build process. It's not like it's an undocumented

There are at least a half-dozen solutions for sending you the logs. Google
may be rolling out one now, based on some reports. And there's DroidDrop,
Flurry, android-log-collector, plus others that have been reported on this
list. For example, I seem to recall somebody just posting on here having a
crash reporter that pushed the data into Google Docs for you.

Add one of these, get the crash data, and you won't have to guess. Or, at
least, you'll be guessing in a narrower range of possibilities.

We haven't got a straight answer about this, AFAIK. This works
fine on the G1, but doesn't work on the N1. If you search the
archives, I think that somebody said that it used to work on the
N1 as well but at some point it stopped working. If true, that
at least says that it's not a hardware issue. But who knows about
other platforms? I know that the iPhone behaves the same way,
so it's possible that it's a hardware related limitation on some
platforms. Pulling up the kernel sources maybe the only way to
settle this, and then only if the accelerometer driver is exposed.

[android-developers] Re: Android 2.1 SQL Server

2010-05-20 Thread Tim

At MobiForms we use the jTDS JDBC driver to support JDBC access to SQL
Server from apps developed using our MobiForms Developer.  In fact
Android supports full JDBC syntax and access to a range of databases.
With MobiForms you do not need to learn Java, XML, Eclipse or the
Android SDK.  Instead MobiForms offers one intuitive drag and drop
development and deployment tool.  All JDBC cursor and recordset
management is done automatically for a range of industry databases
including SQL Server and Oracle.  MobiForms is ideal for novice or
advanced programmers who do not want to spend hours debugging low
level code.  With MobiForms just about any mobile application can be
developed in minutes rather than hours or days.  Additionally, a
MobiForms app developed for Android will work on a range of other
platforms including Windows Mobile without the need for rewriting the
app.

For more information have a look at our web site at http://www.mobiforms.com.

[android-developers] Help!!!! Live streaming (from DSS to android)

2010-05-20 Thread Jez

Does anyone know if the latest 2.1 SDK supports LIVE video streaming
playback in Android.

My setup is using a video decoder which receives a Live video stream
to VLC, which in turn sends this to Darwin Streaming Server, I then
open (android emulator) the media player demo on  rtsp://server ip/
stream.sdp.

DSS shows that the Android emulator is connected and has requested the
stream.sdp, however the buffering on Android shows repeatedly as 0%
with no output of the live video stream shown.

The Question---
Does this mean that Android (as standard) does not support LIVE rtsp
video streaming ?

Re: [android-developers] Petitions to Google

2010-05-20 Thread Leigh McRae

It's my understanding that Android isn't Java compliant so I don't 
understand this comment.  Perhaps I am wrong.


I also don't understand what this has to do with the specification 
anyway as it's a tool issue really.If we are to talk about Java and 
hence Sun, well they have a preprocessor for their j2me stuff as they 
have come to the conclusion that it adds value.  C# uses a preprocessor. 
RIM has a one also.  I really don't understand why it couldn't be added 
and the people that it offends can just not use it.


Perhaps you should try and write an app that isn't an SDK sample?

Re: [android-developers] Petitions to Google

2010-05-20 Thread Leigh McRae

I hear you Mike. I have done this in the past for stuff like PS2 vu asm 
code and even with lua.  The thing is that the only real choice that I 
have seen is to use Eclipse for Android if you want to have support to 
debug.  My Eclipse Fu isn't strong by any means so maybe I am wrong.


Can you give a brief overview as to you dev setup?

Free and paid apps shouldn't be done by a preprocessor for several
reasons: You want to change the content of XML file. an XML
pre-processor is going to be harder. Also you probably won't have the
same files at all and a pre-processor won't really let you
exclude/include whole files.

We will introduce a new build mechanism that will allow you to easily
share code and resources across 2+ application projects that will be
much better at handling this case.

As for the beta vs. final version, yeah, as someone else said, this
makes no sense.


First the OP didn't talk about using a preprocessor for xml.  I 
would agree

that that would be odd and there are better tools for that.  Still a
preprocessor could be used to conditionally include a resource by 
id.  How
about I give you some concrete examples and you can help me see the 
light?



Example 1

//#if BETA
if ( hasBetaExpired() )
System.exit( 0 )
//#endif

Example 2

public final class Assert
{
public static final void RIP( final String msg )
{
//#if BETA
sendReport( msg );
//#endif
System.exit( 0 );
}
}

Example 3

public class Debug
{
void Println( String msg )
{
//#if !RELEASE
Log.d( TAG, msg );
//#endif
}
}

Example 4

//#if PLATFORM_BLACKBERRY   //@ omega =
(float)MathUtilities.acos( cosom );
//#else omega = (float)java.lang.Math.acos( cosom );
//#endif   
Example 5

public static final float VecToHeading( float x, float y )
{
//#if PLATFORM_BLACKBERRY
//@ floatfAngle = ((float)Fixed32.atand2( (int)(x * 65536.0f),
(int)(y * 65536.0f) )) / 65536.0f;
//#else
floatfAngle = ((float)Math.atan2( x, y )) *
57.295779513082320876798154814105f;

if ( fAngle0.0f )
return fAngle + 360.0f;

return fAngle;

[android-developers] How soon is isFinishing() triggered?

2010-05-20 Thread Jeremiah Sellars

...or when is the earliest I can detect it? Here's my situation...

I've got an OpenGL game in the works. When the activity is ended
(however this happens either by Android or user quitting) I'd like
like to do some cleanup. I'm already calling a native function to free
some memory that was allocated and those calls are fine, but I'm also
trying to call glDeleteTextures(). I've tried a few things and
currently I have this in OnPause()...

@Override
protected void onPause() {
super.onPause();
mGSGLView.onPause();

if(isFinishing()){
GSNFreeMem(); //Native cleanup function
}

}

Logcat complains that I'm calling an OpenGL ES API when there is no
current context. I've read some threads about what to look for and
checking for back button presses, etc... seems bad so I want to let
Android tell me when to do this.

[android-developers] Pushing up views above soft keyboard

2010-05-20 Thread abhi

hi,

I am trying to push up the views in my activity whenever a soft
keyboard comes up. I have been partially successful in this, except
that certain views remain hidden behind the soft keyboard.

My XML looks like the below. I am specifying the last RelativeLayout
RL3 containing buttons with the attribute:
android:layout_alignParentBottom=true so that they stay above the
soft keyboard when it comes up. However. the scrollview SV1 which is
above the last RelativeLayout RL3 is not scrolling up completely and
so a part of the scroll view remains hidden behind the soft keyboard.
I have tried to set paddingBottom=70px but that still does not make
the scroll view go up. Any ideas why this is happening?

[android-developers] Re: App causing crash/reboot cycle

2010-05-20 Thread kec6227



 There are at least a half-dozen solutions for sending you the logs. Google
 may be rolling out one now, based on some reports. And there's DroidDrop,
 Flurry, android-log-collector, plus others that have been reported on this
 list. For example, I seem to recall somebody just posting on here having a
 crash reporter that pushed the data into Google Docs for you.

 Add one of these, get the crash data, and you won't have to guess. Or, at
 least, you'll be guessing in a narrower range of possibilities.


I will try one of these, but it sounds like the phone does not stay on
long enough to have any sort of log sending capabilities, and as far
as I know, it does not show a force close window.

You have, of course, overwritten onCreateContextMenu ... right? And you

Is it possible to display a textview above the listview? I tried it by
adding the code for textview above the listview. But then, only the textview

The application fundamentals page at the android site states that

By default, all components of the application run in that process and thread

Is this true for a broadcast receiver as well?

if I have multiple broadcast receivers in a single apk file and do
they all run on the main thread one after the other??

Appreciate looking into this

Sure. All of your activities have access to the one application

in onCreate and onDestroy.)

Re: [android-developers] Re: Maintaining the state when changing the orientation

2010-05-20 Thread Alok Kulkarni

Hi guys , thanks for the replys,
@Sanjay , i have taken care in case of ArrayAdapter for ListViews
I could successfully do save the state of application and also the handlers
problem was solved. What i did is that i used a Main class which extends
Application, whenever onCreate of my Activity gets called , i assign the
Activity reference to a Main class Activity variable.This happens each time
onCreate is called.
@JP, Actually the application is very huge currently. So i will slowly move
towards Service implementation, but for current releases i need to do
changes in the current architecture itself.
But currently i am facing the issue of going OutOfMemory if i keep on
changing the layout from landscape to portratit and vice versa.
I have to take all the drawable images from a runtime folder under my
application as i have themes implementation and themes images come from
server. So i assign drawables at runtime to all the widgets.
When the orientation changes , i reassign the drawables to all widgets.I
have taken care of making the objects null.. And views get null when
onDestroy is called. Also i havent kept the reference of activity anywhere
after onDestroy is called.. IS there anything wrong thats striking to anyone
right now ?
Thanks ,
Alok.

Like in your case, I have apps that need to keep (hundreds of) objects
and state variables that require retention regardless of what's going
on at the UI level. What I've done in order to pick up where I left
off after a rotation change (or, for that matter, when the user calls
the app from the main screen) is to start and bind a Service that I
bind again when the app comes out at the other end. Implement getters
and setters like you normally would to access the relevant data. The
SDK contains a pretty good example how to do all that which you can
use as a blueprint.
The downside is that there's a risk the service gets killed as the
system is scraping for resources, but personally I haven't seen this
happen for a service that's bound to an UI thread. There's people on
the list who know much more about what's going on under the hood in
that regard, perhaps they can chime in.

[android-developers] Re: samsung app store

2010-05-20 Thread Gabriel Simões

. something to think about ...

Why would users need another App Store for the same plataform if it
doesn´t add anything better than the ones we have already?
I´m trying to imagine what will happen if every manufacturer/carrier
decides not to include android market on their custom Android OS
compilations and use their own market. Fragmentation is the smaller of
the problems.
As a developer, I don´t want to have to register my apps in a lot of
places ... check all of them to see comments, reviews, to update
versions, to receive money, to check for issues, etc.
Also, for users this will be terrible since no store (but android
market maybe) will have all the apps available. Also, the user won´t
be able to choose which store to use since market apps normaly aren´t
available for download (for security reasons).
And all this for what? Every manufacturer now want´s to get it´s part
of the standard 30% stores take. Also, every carrier want´s it, so we
will end in an even more fragmented scenario.
This is something the alliance should discuss as a decision for a
future scenario of Android. Also, I hope users opt for devices with
Android Market, as here in Brazil some carriers are already selling
devices without Android Market and have already informed that this
decision is related to the launch of their own markets. This can lead
to a decline in the plataform, for sure.

In the end, I hope Google stops closing it´s eyes and start to improve
Android Market imediately: security problems, web portal´s lack of
features (including search), small description and only 2 screenshots
for developers, etc are just a few of the complains we hear every
single day.

Well, I wish samsung doesn´t take android market off of their
devices  but I don´t believe it can be stopped since it seems
their market won´t be any better so users won´t use it unless they
have to. Business decisions ... and the concept of an integrated app
store goes down the water.

2010-05-20 Thread Nathan

I'm with you on this. I don't want more fragmentation.

Profit is not the only motive, though. They want a market that works
on their HDTVs and DVD players. I don't know if they will be running
Android, but Google doesn't support running the market on non
smartphone devices. Samsung also makes Windows Mobile devices and
other OS devices.

I still think the Android Market would be a better choice where it is

 . something to think about ...

 Why would users need another App Store for the same plataform if it
 doesn´t add anything better than the ones we have already?
 I´m trying to imagine what will happen if every manufacturer/carrier
 decides not to include android market on their custom Android OS
 compilations and use their own market. Fragmentation is the smaller of
 the problems.
 As a developer, I don´t want to have to register my apps in a lot of
 places ... check all of them to see comments, reviews, to update
 versions, to receive money, to check for issues, etc.
 Also, for users this will be terrible since no store (but android
 market maybe) will have all the apps available. Also, the user won´t
 be able to choose which store to use since market apps normaly aren´t
 available for download (for security reasons).
 And all this for what? Every manufacturer now want´s to get it´s part
 of the standard 30% stores take. Also, every carrier want´s it, so we
 will end in an even more fragmented scenario.
 This is something the alliance should discuss as a decision for a
 future scenario of Android. Also, I hope users opt for devices with
 Android Market, as here in Brazil some carriers are already selling
 devices without Android Market and have already informed that this
 decision is related to the launch of their own markets. This can lead
 to a decline in the plataform, for sure.

 In the end, I hope Google stops closing it´s eyes and start to improve
 Android Market imediately: security problems, web portal´s lack of
 features (including search), small description and only 2 screenshots
 for developers, etc are just a few of the complains we hear every
 single day.

 Well, I wish samsung doesn´t take android market off of their
 devices  but I don´t believe it can be stopped since it seems
 their market won´t be any better so users won´t use it unless they
 have to. Business decisions ... and the concept of an integrated app
 store goes down the water.

[android-developers] Protect against broken intent - How ?

2010-05-20 Thread Anthoni

Hello,

In my application I am going to be allowing the ability to call and
start other activities, just like the Android spec allows.
To this extent I use the following code :-

Intent myIntent = new Intent();
myIntent.setClassName(IntentPackage, Fully Qualified Intent);

Now I found out quite by accident if the intent fails to be found, I
accidentally misspelled my intent, it totally crashes my application
not only that nullifies my application object as well (I have a class
that extends Application). I've tried to trap this but it still always
crashes.

Can someone please advise me on how to protect my app against broken
intents (misspelled or otherwise) ?

Regards
Anthoni

Because this is hack that goes against the Android way of data and message
passing and will lead to problems - like if you press Home after going to
the second activity, get booted from memory, and come back to that activity.
Your static data will be null and your second activity will die a horrible
death.

 Also I have one suggestion regarding pricing: Android Device Seeding
 program is over but Google could support developers while upgrading
 their dev phones according success of their apps (like  1
 downloads with rating   50% discount,  25 downloads with
 rating * 100% discount etc). I believe that this can be small
 support to developers in countries where it is prohibited to sell apps
 (which is IMHO majority of the world) and they are doing good job for
 Android.

 I'm currently providing free apps (as I can't buy and sell on Android
 Market from my country) and to buy multiple phones to cover various
 flavors of Android is quite expensive hobby ;-)

 Have a good day

Free and paid apps shouldn't be done by a preprocessor for several
reasons: You want to change the content of XML file. an XML
pre-processor is going to be harder. Also you probably won't have the
same files at all and a pre-processor won't really let you
exclude/include whole files.

We will introduce a new build mechanism that will allow you to easily
share code and resources across 2+ application projects that will be
much better at handling this case.

As for the beta vs. final version, yeah, as someone else said, this
makes no sense.


First the OP didn't talk about using a preprocessor for xml.  I 
would agree

that that would be odd and there are better tools for that.  Still a
preprocessor could be used to conditionally include a resource by 
id.  How
about I give you some concrete examples and you can help me see the 
light?



Example 1

//#if BETA
if ( hasBetaExpired() )
System.exit( 0 )
//#endif

Example 2

public final class Assert
{
public static final void RIP( final String msg )
{
//#if BETA
sendReport( msg );
//#endif
System.exit( 0 );
}
}

Example 3

public class Debug
{
void Println( String msg )
{
//#if !RELEASE
Log.d( TAG, msg );
//#endif
}
}

Example 4

//#if PLATFORM_BLACKBERRY   //@ omega =
(float)MathUtilities.acos( cosom );
//#else omega = (float)java.lang.Math.acos( cosom );
//#endif   
Example 5

public static final float VecToHeading( float x, float y )
{
//#if PLATFORM_BLACKBERRY
//@ floatfAngle = ((float)Fixed32.atand2( (int)(x * 65536.0f),
(int)(y * 65536.0f) )) / 65536.0f;

The main reason I mentioned XML was for the package of the app that
needs to change to ship both a free/lite and a paid/pro version of an
app.

This is a typical use case that was problematic before since changing
the package name required refactoring (due to the new package for the
R class).

Now, if you use the newly released tools r6 and ADT 0.9.7 you can
create library projects and share code/resources between your paid and
free versions.

[android-developers] Multitouch / Pinch To Zoom in Android 2.2?

2010-05-20 Thread Mariano Kamp

Hi.

In Android 2.1 update 1 multitouch was silently added. Unfortunately
it is only available when also the zoom picker is **active**?! I am
sure there are cases where that setting makes sense, but it was not
possible to separately turn on one or the other.
I thought they didn't want to change the API with with an update-1
and would now surface the API in Android 2.2.
At least my initial check didn't turn up anything in that respect though ;-(.

Also I don't know if multi-touch pinch/zoom still works in Android
2.2, because I don't know how to test it on the emulator. Does anybody
know or has other insights to share?

On a sidebar. Do I see this right? The developers get the new Android
version before their users? Loving it! Thanks.

Cheers,
Mariano

Btw. OT, but the first 45 minutes of the keynote totally rocked. Much

Yes it does - expand the bug report and the section that says Stack Trace

I already have one report that's been generated both from my current and the
previous version of my app.

[android-developers] Re: Issue with setBuiltInZoomControls on HTC Incredible

2010-05-20 Thread Stormtap Studios

I'm noticing a trend here. We too are experiencing issues with
WebViews on the HTC Incredible.

We're having problems with the content being strangely zoomed in when
it loads up. We're also experiencing a strange behaviour where when
the user scrolls the view a gray or black square grows from the top of
the view downwards as you scroll. When you reach the bottom of the
view it completely fills the view.

Also, sometimes our app will crash when the user clicks on links for
the view.

I think this is starting to show that there's definitely something
wrong with WebViews on the HTC Incredible as we also don't detect this
behaviour on an unmodified Android Dev Phone 2, or the Nexus One.

I use aWebViewto display JPGs to users. TheWebViewallows me to
easily add zooming functionality without having to write the code to
actually do it.

Anyway, I've been getting a lot of Bug reports from users with an
HTCIncrediblethat the zooming is broken. I bought an HTCIncredible, and
tested and sure enough zooming causes theWebViewto be surrounded by
a box. It's difficult to explain, but basically panning and zooming is
not possible. The only way I can get theWebViewto properly display
the JPG is by setting setBuiltInZoomControls(false).

I ran the app on another 2.1 phone (Droid), and it works fine. Works
fine on my Nexus One, and even in the 2.1 Simulator.

Anyone else run into this problem?

Here's the code i have for myWebView:

webview= (WebView)
findViewById(R.id.webview);webview.getSettings().setLoadsImagesAutomatically(true);webview.getSettings().setJavaScriptEnabled(true);webview.getSettings().setBuiltInZoomControls(true);webview.setInitialScale(initialScale);

Then I just do:

webview.loadUrl(file:// + getFilesDir() + / + filename);

Thanks,
Felix

You're correct, but that's only for crashes.  ANRs don't show version
in the report.

Again, date and version # are critical for developers to have with
reports.
