[android-developers] upgrade to 4.2.2 -- Eclipse sees device offline and unknown
Hello, Unfortunately, I foolishly proceeded with the upgrade of my nexus 4 from 4.2.1 to 4.2.2 Now, even though the device is configured for USB debugging and connected as a camera device, although it sees it Eclipse cannot access it as the device is reported to be offline. Does anyone have any information about this problem, ways to resolve it, or experienced the same problem? Any help would be greatly appreciated. If the problem is known and unnsolved, could anyone let me know how I can downgrade back to 4.2.1?

[android-developers] Finally someone at Google gets it - Please read you might like it
Hello, I don't know how many of you have read this. I have stopped paying too much attention to the postings on this group because of the problem highlighted by the writer. Perhaps, someone has already posted about this article. If this is the case, I apologize in advance for the duplication and wasting your time. https://plus.google.com/112678702228711889851/posts/eVeouesvaVX If you have not, you might/should want to. It's a long article by a Google developer who, unlike many at Google including Google employees who contribute to this and other Google groups ( you know who you are) seems to understand to build a platform. Please note that I did not say an open platformbut a platform. If you wonder what the difference is, please read the article. Although it does not help my work, I feel somewhat relieved and gratified. If you have the time and desire, please also read carefully the part of the article about accessibility and security.

[android-developers] Re: cacerts.bks availability on device
Hi,
Your entry was very useful. I was wondering if you could offer some
more assistance. I added
TrustManagerFactory mTrustManagerFactory = new
TrustManagerFactory(mTrustManagerFactorySpi, null, malg);
KeyStore ks = null;
try {
mTrustManagerFactory.init(ks);
} catch (KeyStoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
to onCreate in my application. I have three questions:
1) Is this what you meant by create a TrustManagerFactory and specify
a null KeyStore in the init() method?
2) How do I check that it worked? Access the TrustStore property
informtion?
3) If I was successful, in order to take advantage of having all the
certificates in cacerts.bks available to my application, would I need
to change my application's entry in files such as packages.xml?
Thanks for your help.

Also, I wouldn't rely on the file necessarily always being available

For a desktop J2SE installation, you would set the Java system
property javax.net.ssl.trustStore on the Java command-line to point
to the default KeyStore. In contrast, on Android, if you create a
TrustManagerFactory and specify a null KeyStore in the init() method,
then Android sets the javax.net.ssl.trustStore Java system property
to point to thatcacerts.bks file and you therefore get your
TrustManagerFactory populated with those certificates (as a side-
effect, you can also find out where the file is by querying the
javax.net.ssl.trustStore Java system property).
Seehttp://developer.android.com/reference/javax/net/ssl/TrustManagerFact...
And, for those who are interested, the code where this is done is on
lines 53-62 here:
http://android.git.kernel.org/?p=platform/dalvik.git;a=blob;f=libcore...
While this mechanism also doesn't appear to be documented, I would
suggest that using this is preferable to relying on the particular
pathname of thecacerts.bks file.

Would this certificate store be present on all the devices ? I

mention of it.
Does the default Android browser and mail client use it ? If not do
they ship with their own certificate store ?

[android-developers] 2nd phone line Line2 iPhone
Hello, Probably, you have heard of the iPhone application called Line2. In short, it gives an iPhone a second phone number and line complete with contacts list, voice mail, etc., etc. I have been working on an application in the same area for Android but have run into the system's security/permission barriers. I was wondering if anyone has thoughts as to how the Android security/ permission issues inherent when attempting to develop an application such as Line2 could be resolved. My hope is that on an open system such as Android, developing an application such as Line2 would not be harder than it is on a closed system such as the iPhone. Thanks.

[android-developers] Re: 2nd phone line Line2 iPhone
Hi Mark, Did you actually take a look at Line2? If you have, would be interested in your more detailed feedback. I do not believe that any of the Android applications you mention performs the same functions as Line2. I may be mistaken but I do not believe that Line2 is simply a VOIP application. Based on my limited understanding (I could be wrong), Line2 actually manages calls either via ATT or the Internet (VOIP), i.e. works alongside/replaces the iPhone phone application. With regards to the security/permission barriers I refer to below, please refer to any attempt to access phone application related functions. Have you tried to do that in an application? If you have, which ones did you try to use? I am very interested in gaining a better understanding of how one could use phone application functions in one's own application (just like Line2 does on the iPhone). Thank you.

Understood but I am not interested in VOIP. I am interested in implementing phone application functions. Again, based on my limited understanding, Line2 is not just a VOIP application. It actually performs phone app functions and can let users pamek calls over the ATT network, but I could be wrong. As far as I know, in Android security/permission barriers prevent any application from using/implementing phone app functions. Thank you.

[android-developers] Re: 2nd phone line Line2 iPhone
Mark, I am not sure you are correct (although you seem very sure that you are). I have read through the Line2 information. I guess I have a different understanding of what they mean by what they mean by dual cellular/voip application. But, I could certainly be wrong. However, I certainly did not want to get into a debate about Line2. Frankly, who cares? And, probably I was not very clear. I would not want to replace the default phone application. But, I think it is reasonable to be able to access/perform some of its functions alongside it. This, as I am sure you know, is not possible because of permission/security limitations. Thank you.

[android-developers] Re: Block Switch App
Dianne, You are a smart person, and should recognize that what you state as being a fact, and inherently right is, in fact, simply your (Google's) opinion and position and, unlike most of us, you are in the position to enforce that opinion and position. While it is true that since Google invested significant resources into Android (for its own interest and good), it is acting normally in exercising control over the platform, I find it somewhat irritating that Google tries to portray itself as a promoter of Open Source. It is not. Google uses Open Source to further its corporate goals. Plain and simple. Nothing wrong with that. When Google's interests and thos of the Open Source community at large coincide, everybody is happy. When they don't Google enforces its position and acts based on its corporate interests. Claiming, as some do, that Android is open and anyone can go and implement his/her own distribution is somewhat disingenuous. I will let you figure out why it is. Alex Donnini On Dec 10, 2:28 am, Dianne Hackborn hack...@android.com wrote: Taking over the home key will not be done with a permission, period. This is way you get to take over the home key: by having an intent-filter saying you can be home, and letting the user explicitly select your app at the point where they press home. The home key is too central to the user's security for it to be misdirected by some random application they installed a month ago that at time time seemed okay to be able to intercept home key (if they looked at it at all). And as far as the lock screen goes -- nobody has said that there would never be support for third party lock screens. Right now, however, there isn't, and there is no near-term plan to do so. If you want to see why, start perusing the lock screen code starting here: http://android.git.kernel.org/?p=platform/frameworks/policies/base.gi...http://android.git.kernel.org/?p=platform/frameworks/policies/base.gi... Lock screen management is extremely complicated, and not in any shape at this point to be user replaceable. At the very least, all of the points of contacts with the rest of the system (complicated interaction with the in-call experience in various states, dealing with emergency dialing that is legally required and the related SIM states that go with it, deep fragile interaction with low-level power management and event dispatching, etc) needs to be deeply abstracted out of the UI itself. And then there are all of the issues of dealing with this now no longer trusted third party code when it crashes or otherwise misbehaves. This isn't just oh those mean Android people won't let me write a few lines of code to replace the lock screen.

[android-developers] Re: Block Switch App
Hello Jason, I would be glad to. Let me give you a simple example that does not quite fit but should give you an approximate idea of what I mean. Gold mining is an open activity. Anyone can go and look for gold. An entire mythology has grown reinforcing the dream that ANYONE can go and get rich looking for and finding gold. In fact, there have been a few (very very few) individuals that have struck the proverbial gold mine. However, for the vast majority of humanity, gold mining is completely out of reach. In fact, gold mining is very big business. As I said, this is a very small and imperfect example. To further clarify, the keywords are scale and resources. It does not matter how open something in theory is. Ultimately, if the scale and resources are not there, it will die or, live in a very small niche. By the way, ever heard of the word sycophant? Perhaps, I am being too harsh but whenever I read these postings, that word comes to mind. I am puzzled by the number of individuals that rise in the (aggressive) defense of Google and its employees, as if they needed to be defended, and don't do a good enough job of defending themselves as regularly proven by Dianne. Google and Android are not causes. They are a company and a product. The packaging may be a little different, and updated, but ultimately Google is not and cannot be any different from, say, IBM, Apple, Microsoft and Oracle. And, there is absolutely nothing wrong with that.

Unless I am mistaken, at present the getCid() method in NeighobringCellInfo depending on the network in use is not directly usable as it returns values which need to be decoded/unscrambled. The getNetworkType() function is necessary to find out the network is being used and if necessary, as in the case of 3G networks (e.g. sample NeighboringCellInfo entry from a 3G network [[6c at 0], [74 at 0]] ), unscramble the getCid result.

[android-developers] Re: Find long/lat distance X from current location
Thanks all for the suggestions. Mark, I am well aware that there is an infinite number of points on the circle at distance X from a known location. To start with, for my application, my plan is to find 16-64 of the locations at distance X from my location. That should be sufficient. The problem I have is that, unless I am mistaken, all GC formulas are of the form d = some formula using lat/lng of two locations. In my case, I know d and lat/lng of one location. I need to find lat/lng of the second location. In order to solve this kind of equation (two unknowns), I could use some form of estimation or some other approach. Unless I am missing something obvious, I think I may need to figure something out using the geometry of a circle combined with some type of estimation. Thanks.

[android-developers] Re: Find long/lat distance X from current location
Thanks. I think I will use the parametric formulas for calculating the coordinates of points on a circle using increments of 1 degree. If that turns out to be too ambitious (because of the performance hit generated by the additional processing once I have calculated the 360 possible locations), I will reduce the number and see what happens.

[android-developers] Find location at distance X from current location
I apologize if this message is a duplicate but I looked for an earlier message I had posted about this same subject and could not find it. Hello, I was wondering if anyone has ideas, or could help me solve this problem. I would like to find the location (lat, lng) at distance X from my current location. I realize that the number of such locations is infinite (all the points on the circumference of the circle with radius X with center at my current location) but I was thinking that I would limit the collection of such location to a sample (say 32, or 64 samples). I would appreciate any ideas and suggestions. Thanks. Alex Donnini --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Direct access to GEARS geolocation without going through the browser interface
Mark, Thanks. I am aware of that. My question was different. Have you looked into the GEARS geolocation class? If you have, you will have seen the three Android Java classes I refer to below. My question is about the purpose and intended use of those classes. Given that Google has removed all of the MASF related functions from the SDK, very few ways are left for accessing location information starting from WIFI, GPS, or cell data. Fortunately, it appears that the http://www.google.com/glm/mmap interface is still accessible (for how long???). GEARS geolocation offers a way to derive location information starting from GPS, WIFI, or radio information. However, it would be incorrect to assume that access via a browser is optimal, or appropriate for all applications. The fact that geolocation includes Android-specific public Java classes to access GPS, WIFI, and radio information leads me to believe that, in fact, there is (should be) a way to directly access geolocation functions from an Android application without going through the browser. If you are not familiar with this area, that's OK, just say so. Thanks.

[android-developers] Direct access to GEARS geolocation without going through the browser interface
Hello, I have searched this group's archives, and several other sources for information on direct access to GEARS geolocation functions from an Android application. To date, I have not found any. geolocation includes three Android-specific public Java classes, AndroidGpsLocationProvider, AndroidRadioLocationProvider, and AndroidWifiLocationProvider. The fact that they are Android-specific and that they are public lead me to conclude that I should be able to use these classes in my application. However, not surprisingly, when I try to access these classes, my application fails (see log below) because, among other things, I have no way to correctly identify nativeObject in the java classes. I would appreciate anyone's feedback, suggestions, and help in resolving this problem. At the very least, I would like to understand the purpose of the three Android-specific public Java classes, and how we should use them. Thanks.

[android-developers] onTap display toast or message
Hello, I looked for any information about onTap event processing for itemized overlays in this group. There is a lot of useful information but I could not find the answer to one question. The tutorial by Mark Murphy on itemized overlays, http://androidguys.com/?p=1413 describes how to generate a Toast message whenever an onTap event occurs. In his case, the custom itemized overlay activity is included in the main activity. In my case, it is not. My custom itemized overlay activity is included in the application package as a public activity. This means that the line Toast.makeText(NooYawk.this, items.get(i).getSnippet(), Toast.LENGTH_SHORT).show(); will not work as is. I have had trouble in correctly identifying the context for the Toast. Attempts to use the main class' (the one calling the custom itemized overlay class) context have not worked. I would appreciate it if anyone could suggest how I could resolve this issue. Incorporating the custom itemized overlay class in the main class is not a desirable option. Alternatively, I would appreciate any suggestions for generating a display of the title and/or snippet information for markers on a map. Thanks. Alex Donnini P.S. the onTap event works fine (Log.i statements in the onTap method display the correct information for each marker tapped) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Hi Mark, Thanks. What I meant is that I thought that in your example, SitesOverlay is an inner class of the map activity NooYawk.

[android-developers] Re: Android 1.5 SDK, Release 2 -- TelephonyManager
Hi Liam, You need to have Android libraries in your project's Libraries build path (this means that you need to have the Android project source accessible from your IDE (e.g. Eclipse), and then make sure that the Android libraries precede the Android SDK library in the build order. I hope this helps. Alex On Jun 17, 4:29 am, Ne0 liamjamesalf...@googlemail.com wrote: As you can probably tell, i am new to android development and rusty on java.

[android-developers] Android 1.5 SDK, Release 2 -- TelephonyManager
Hello,
I have a simple/quick question.
Does TelephonyManager in Android 1.5 SDK, Release 2 (the SDK version I
am using) contain the
getNeighboringCellInfo()
method?
The reference documentation,
http://developer.android.com/reference/android/telephony/TelephonyManager.html#getNeighboringCellInfo()
seems to indicate that it does.
However, if you try to use getNeighboringCellInfo() in an application,
it does not work generating cannot be resolved to a type error.
If you add the Java libraries framework intermediaries library from
Android the cannot be resolved to a type error is resolved but the
application crashes at run-time (VerifyError, not surprisingly).
My hope is that I am overlooking something obvious, and/or making a
simple mistake.
If my mistake is in the code below, I would appreciate seeing a
snipped that does work.
Thanks.
Alex Donnini
P.S. here is the code of the application I wrote to test
getNeighboringCellInfo()
package com.telephonytest.com;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.telephony.NeighboringCellInfo;
import android.telephony.TelephonyManager;
import android.util.Log;
public class TelephonyTest extends Activity {
private static String TAG = TelephonyTest;
private static TelephonyManager mTelephonyManager;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTelephonyManager = (TelephonyManager)getSystemService
(TelephonyTest.TELEPHONY_SERVICE);
ArrayListNeighboringCellInfo mNeighboringCellInfo;
mNeighboringCellInfo = new ArrayListNeighboringCellInfo();
mNeighboringCellInfo = (ArrayList)
mTelephonyManager.getNeighboringCellInfo();
for(int i = 0; i mNeighboringCellInfo.size(); ++i)
{
Log.i(TAG,mNeighboringCellInfo.get(i) -
+mNeighboringCellInfo.get(i).toString());
}
}

[android-developers] Re: Android 1.5 SDK, Release 2 -- TelephonyManager
Liam,
Casting from List to ArrayList works fine. It does not cause an error.
I guess I run into a problem because my target is Android 1.1, not 1.5
You can get cell and location related information in a number of
ways:using other applications as starting point. For example:
- radioinfo.java
[platform/packages/apps/Settings.git] / src / com / android /
settings / RadioInfo.java
- cellfinder
http://code.google.com/p/codetastrophe/
- AndroidGpsLocationProvider.java
http://code.google.com/p/gears/source/browse/trunk/gears/geolocation/AndroidGpsLocationProvider.java
With regard to duplicating the fieldtest application functionality,
you need working getNeighboringCellInfo() and other neighboring cell
related function.
Note that if you do a dexdump of fieldtest, you will see that it uses
OEM RIL related functions to extract neighboring cell related
information (however, I could be wrong about this).
I hope this helps. Unfortunately, I am still stuck with regards to
getNeighboringCellInfo().

Yes it does, though you have make sure that you are building your app
for 1.5 versions only, this is done when setting up your project using
Eclipse, thats how i do it anyway.
I have yet to test my code on an actual phone, though there is one
thing you may be clear up for me, its been many years since i have
used java, you are using ArrayList, though the documentation
describes getNeighboringCellInfo() as returning a List, are these
the same thing? If not it may be an error in your code, mine works on
the emulator using List though it returns NULL.
Hope this helps.
On a different note, i am trying to get other info for my app, do you
know how to get anything other LAC, CID, Neighbour list with power?
Like the Field test App? Cheers

Do you honestly think insulting Google developers will improve your

Yet, getNeighboringCellInfo() does not work. Any attempt to call it in
an application results in application failure.
File a bug report athttp://b.android.com. I didn't find any issues
referencing that method. If you can attach a project that reproduces the
issue, so much the better.
BTW, the Android 1.5 docs say you need the ACCESS_COARSE_UPDATES
permission -- do you hold that permission? That might be a documentation
bug, in that I cannot find any other reference to that permission, so
you might also try ACCESS_COARSE_LOCATION. None of that would seem to
line up with the stack trace you posted in that one thread, but you
never know...

Hi Mark, I had not seen your comment about insulting Google developers until now. Saying that they do not like to address certain question is insulting?? Come on... so thin skinned? The fact of the matter is that asking certain questions gets no answers. Why is it that it is OK for developers to ignore my questions, and not consider that insulting (being ignored), while simply saying that they are ignoring my questions is insulting? I am truly puzzled by this. Alex Donnini On May 29, 5:21 pm, alexdonnini alexdonn...@ieee.org wrote: Sorry Mark, I thought you had tried it. I will file a bug report. Thanks.

[android-developers] Accessing rild socket
Hello,
Below, you will find the source code for a simple application testing
access to the rild socket in dev/socket.
Before running the application, I manually changed permissions on rild
in dev/socket to allow r/w/x for all users.
The application below is based in large part on code I found at
http://all4dev.blogspot.com/2009/02/android-localsocket-localserversocket.html
As originally written, the application works.
When I changed it to use rild socket as the conduit for communication
between receiver and sender, it stopped working.
Specifically, I believe that connection to the rild socket (s.connect
()) never completes. No exceptions are produced either.
I would greatly appreciate it if anyone could let me know where they
think I made a mistake, why the application does not work, and what I
should do to fix it.
Thanks.

[android-developers] read from local socket does not work
Hello, I was wondering if anyone would explain to me why the code snippet below does not work: s.getOutputStream().write(length); s.getOutputStream().write(data); Log.i(TAG, data from socket - +Integer.toString(s.getInputStream().read())); In my application, the code is surrounded by try/catch. It does not generate an exception. s is an instantiation of LocalSocket. The code does not work because the attempt to read data from the socket never completes, i.e. no data is ever returned from the socket (via the Log.i statement). I would appreciate it if anyone could help me understand if and where I made a mistake. Thanks.

Anyway, I assume you want to cell tower location and such. Try
creating a listener, and then registering your listener with the
TelephonyManager.
Start by giving your application the following permissions:
android.permission.ACCESS_FINE_LOCATION
android.permission.ACCES_COARSE_LOCATION
Then, create your listener:
// implement both phone state listener and location listener.
public class PhoneSignalListener extends PhoneStateListener
implements LocationListener{
/**
* @param signalStrength signal strength in ACU.
*/
public void onSignalStrengthChanged(int signalStrength){
float signalPercent = ((float)signalStrength)/31f * 100f;
SignalStrength.setSignalStrength(signalPercent);
SignalStrength.setSignalStrengthASU(signalStrength);
}
public void onCellLocationChanged(CellLocation cellLoc){}
public void onLocationChanged(Location loc) {}
public void onProviderDisabled(String arg0) {}
public void onProviderEnabled(String arg0) {}
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {}
}
And then you register it with TelephonyManager. In your application's
main activity (Activity.onCreate()):
public class MyActivity extends Activity{
public void onCreate(Bundle savedInstanceState) {
TelephonyManager telManager = (TelephonyManager)
this.getSystemService(Context.TELEPHONY_SERVICE);
telManager.listen(new PhoneSignalListener(),
PhoneStateListener.LISTEN_SERVICE_STATE |
PhoneStateListener.LISTEN_SIGNAL_STRENGTH |
PhoneStateListener.LISTEN_CELL_LOCATION);
}
}
As the phone location changes you get the information delivered,
wrapped in a pretty package with a bow, to the Phone signal listener.

public class PhoneSignalListener extends PhoneStateListener
implements LocationListener{
/**
* @param signalStrength signal strength in ACU.
*/
public void onSignalStrengthChanged(int signalStrength){
float signalPercent = ((float)signalStrength)/31f * 100f;
SignalStrength.setSignalStrength(signalPercent);
SignalStrength.setSignalStrengthASU(signalStrength);
}
public void onCellLocationChanged(CellLocation cellLoc){}
public void onLocationChanged(Location loc) {}
public void onProviderDisabled(String arg0) {}
public void onProviderEnabled(String arg0) {}
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {}
}
And then you register it with TelephonyManager. In your application's
main activity (Activity.onCreate()):
public class MyActivity extends Activity{
public void onCreate(Bundle savedInstanceState) {
TelephonyManager telManager = (TelephonyManager)
this.getSystemService(Context.TELEPHONY_SERVICE);
telManager.listen(new PhoneSignalListener(),
PhoneStateListener.LISTEN_SERVICE_STATE |
PhoneStateListener.LISTEN_SIGNAL_STRENGTH |
PhoneStateListener.LISTEN_CELL_LOCATION);
}
}
As the phone location changes you get the information delivered,
wrapped in a pretty package with a bow, to the Phone signal listener.

[android-developers] Change connection programmatically
Hello, I have been looking for a way to programmatically change the active connection on a G1. for example, I would like to be able to switch from g3 to wifi by first disconnecting the g3 connection. When it comes to WIFI, enabling/disabling WIFI, and connecting/re- connecting to a WIFI access point is fairly straightforward. However, when it comes to non-WIFI connections, I have not been able to find the equivalent classes and methods. Please note that, unless I am mistaken, the ConnectivityManager class does not include any methods for managing connections. It's just for accessing information about a connection, and manage some configuration settings. I would appreciate any ideas and feedback. Thanks.

Hi Mark, Thanks for the quick reply and the pointer. I replaced new FileWriter(/data/+fileName) with openFileOutput(fileName, 0) it worked as openFileOutput writes into files (or creates them if they do not exist) in an application's private storage space. The documentation for getFilesDir states: Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

is the chunk of code where I am trying to do this:

items[i] = new TextView(this);

What happens is every button I click just has the last intent settings
so no matter which one I click the next screen shows that I clicked
the last item. I also tried to do this by using an array of intents.
But that gives me an error when I click a button that I have not been
able to figure out.
So how should I be doing this? Am I taking the wrong approach
completely or am I just missing something small?
Also, Im trying to use the wsimport tool to set up the Amazon API but

[android-developers] Re: Listening for dynamic buttons created by an adapter
Hello Mark,
I have been trying to implement the same functionality as Moazzam.
Specifically, I want each row in my list to have a delete (in my
case a process kill) button.
I read carefully your very good tutorials on lists, and tried to
follow the approach you describe in tutorial #5 (see the code below).
The result is as follows:
1) Each row does have a kill button
2) The first row is always blank (except for the kill button
3) On the kill button in the first row is active, i.e. performs the
required action
4) When clicking on the kill button in the first row, the item at
the bottom of the screen (the last visible item) is killed
a) I have not been able to wire all buttons
b) The button which is wired does not act on the desired item because
the value of the position parameter returned by getView.
I would appreciate your thoughts (or anyone else's) on this, and any
pointers regarding the errors in my code.
Thanks.

The easiest way I know of is to subclass your adapter, override
getView(), inflate your own row Views, and attach a listener at that
point, since you have eachButtonobject handy as part of the inflation
process.
You can get an idea of the concept by reading my Fancy ListViews
series of posts over on AndroidGuys (http://androidguys.com). However,
they were mostly from this summer and were written for the M5 SDK, and
so will require some changes to get the source code samples to run on
Android 1.0r1.

[android-developers] Re: process ids
Ludwig,
Thanks. I was aware of the /proc structure. ps gets its data from /
proc/stats
I thought that using ps would minimize the possibility of future
incompatibilities.
when running the code I listed below, it does not fail. However, all
it seems to retrieve is the column headers.
Note that when I run the code on a Linux desktop (via Eclipse). The
expected output, the entrie list of processes, is produced.
So, at this point, I wonder why when running the code in the Android
emulator, all I get is the column headers.

Thanks. I understand the risk in going for direct access.

Sorry, we don't currently have a high-level API for doing this. As a
hack, you can read /proc directly, but that is not something that is
part of the SDK and so you have no guarantees of it working on future
releases or other phones.

Hello,
Would anyone be able to tell me (or point me in the right direction)
how I could retrieve the pids and related process information as
reported, for example, in DDMS in an Android application?
I have been able to put together a small application that retrieves
information about all tasks running
(ActivityManager activityManager =
(ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
ListActivityManager.RunningTaskInfo runningTasks =
activityManager.getRunningTasks(30); )
However, if possible, I would like to retrieve task and process
information at a higher level of granularity (or, if you like, at
lower level).
Any help would be greatly appreciated.
Thanks.
