[android-developers] Autocomplete widget - not working - code attached

[Anees]

Hi experts,

I am trying to implement a dynamic auto complete widget in android. I
am done with the major functionalities and the auto completion
implemented is for youtube video search.

When I start typing a letter or two, the auto-completion is not
working. But when I type three letters or more it works prefect. It
also works when I type two letters and hit a backspace. I do not know
what is wrong with the code.

Code is as follows

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class SendUrl extends Activity {
/** Called when the activity is first created. */
Button button;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
Intent picMessageIntent = new Intent(
android.content.Intent.ACTION_SEND);
picMessageIntent.putExtra(Intent.EXTRA_SUBJECT, 
Here's a cool
youtub video);
picMessageIntent.putExtra(Intent.EXTRA_TEXT, 
Go to url: +http://
google.com/);
picMessageIntent.setType(plain/text);

startActivity(Intent.createChooser(picMessageIntent, Send your
url using:));
}
});
}
}




Experts, kindly guide me. I would be obliged if you can point out
where I have gone wrong with the code.

Any help in this regard will be well appreciated.

Looking forward,
Regards,
Anees

A task, as a logical collection of activities, is unrelated to a physical
process.

 Working on a little sub-project to do with task switching and I came
 across an oddity (for me)
 on RecentTaskInfo.


 If I start a browser (Dolphin for example)  and then exit using their
 menu exit option
 what I see is that in RecentTaskInfo the id is still positive.  In
 theory it is running
 because the id is not -1.
 If I return to home then launch the browser again the id number is now
 different.
 I would expect this if the last one was actually ended.

 DDMS shows the browser and after the menu exit press DDMS shows it
 going away.  The
 presence and absence is also confirmed by looking at the
 RunningTasksInfo.

 Any thoughts?  This seems only to happen with browsers.  What am I
 missing?

Re: [android-developers] Re: Shared Memory

[Dianne Hackborn]

There is really no need to use android:sharedUserId.  The common way to do
this on Android is to put your data behind a content provider, which others
can call ContentResolver.openFileDescriptor() or related to get access to
the file.  The content provider opens the file (so it doesn't need to play
uid games to allow others to access it), and returns the file descriptor.

To make it so only your other apps can get to this file, in the .apk
containing your content provider define a signature-only permission that is
required to access the content provider.  Then all of your apps (signed with
your cert) can access the provider, and nobody else can.

On Thu, Oct 21, 2010 at 8:37 PM, Bob Kerns r...@acm.org wrote:

 Actually, you can arrange for them to run in the same process, if you
 supply both the android:sharedUserId attribute on the manifest
 element, and the android:process attribute on the application element,
 and you sign them both with the same signing certificate.

 You'll also have to work out how to share access to the information,
 as the applications will have been loaded by different classloaders,
 but there are ways that can be done.

 But I'd question whether that's really what you want or need to do.
 That's really not how the system is designed to be used normally. A
 service, or sharing using android:sharedUserId to allow access to each
 other's data, or even persisting the data off the device in a web
 service are more usual approaches. You really didn't say what you are
 trying to accomplish, so we can't really make a more specific
 recommendation.

 I think that an easy way to tamper-proof apk would be:

 1) Android Market computes a checksum for the apk when the apk is

 2) In the License Response (eg. in one extra), Android Market send

 3) The aplication computes the same checsum of itself. If the values

 This could be very easy to do for Android Market developers...

Can you see/play the files if they live on your sdcard using the

No, there cannot.

You strategy looks foreign to me.  Can you explain in english what

Why are you calling your CreateLayout twice in onCreate?  And even

[android-developers] Re: LVL found to be easy to crack

[Jose]

But you can check for the checksum in dozens of differents places in
your (ofuscated of course)  code. It´s  very easy and very fast
This will raising the bar for piracy one step more

  I think that an easy way to tamper-proof apk would be:

  1) Android Market computes a checksum for the apk when the apk is
  uploaded
  2) In the License Response (eg. in one extra), Android Market send
  this value
  3) The aplication computes the same checsum of itself. If the values
  don`t match, just finis()

  This could be very easy to do for Android Market developers...

First of all it's much harder to bypass especially if you are dealing
with optimized code and you will have to do it at least twice (for arm
abi and armv7 abi). Event toolchain setup is more complicated.

[android-developers] Re: ListView OnClickListners Issue

[Doug]

Without looking at the code you should have provided, are you
registering an onClick listener on the ListView itself, or an
onItemClickListener?  Only one of those really make sense.

Re: [android-developers] Re: ListView OnClickListners Issue

[Vinay Julme]

I had the similar problem with the checkbox.

This link helped me out.
http://stackoverflow.com/questions/1121192/android-custom-listview-unable-to-click-on-items

http://stackoverflow.com/questions/1121192/android-custom-listview-unable-to-click-on-itemsIt
states that these check boxes sort of overrides the onListItemClick, and
imposes its own methods over ListItem. So we would have to set
android:focusable=false for the checkbox. In your case it maybe same and u
would have to set focusable as false for the button.

Weired but yes it happens.

Tell us if it worked for you?

 What happens is it imposes it's will on the entire ListItem, and sort of
 overrides the onListItemClick.

[android-developers] How can I access gallery from HTC Desire?

hi all.

I am just wondering why I cant access the gallery using the code

Intent gallery = new Intent(Intent.ACTION_VIEW, Uri.parse(content://

startActivity(gallery);

but when I installed the 3D gallery from cooliris, it is already
possible.
I can access the images from the installed 3D gallery.
But why cant I access the preinstalled gallery on the device?

Thanks letlite,

However I want to be able to display the numeric keypad without having it

So I want the user to be able to click a button on my UI, the keypad pops up
in numeric form and then I want to be able to listen to what they press on
the keypad.

[android-developers] Error with DB onUpgrade

Hi,
I have multiple databases in my app.At the start of the application ,
i initialize all the databases and access columns from the required
tables.What i did is , for one of the databases  i incremented the
version of the DB. So now i have started getting error of  No Such
table say ABCD while compiling  query.This table is in another DB
than the updated DB. I dont have any code in the onUpgrade right now..
Is there any thing thats striking anyone why this behavior is
happening? Is there anything that happens in the onUpgrade method that
causes all the DBs to be inaccessable temporarily. I am saying this
because if i place a breakpoint in onUpgrade and debug , then i wait
for a few seconds on the 1st stmt in onUpgrade and then everything
works fine...

[android-developers] Re: Android serial port

[FrankG]

a) wrong group : use android-platform

b) maybe you could change the usb gadget on your device and provide an
composite usb device
   with a serial communication port

   But to change the framework will be not so easy.

   IMHO you have to adapt the kernel, create your own kernel -
framework communication via
   your own sysfs entries and so on ...

   But all not the scope of this group as this outside of the sdk

   Good luck ! Frank

[android-developers] my activity lost visibility after unlocked screen...

[kevindroid]

I have a broadcast receiver to listen the incoming sms and launch an
activity after received any.

After the activity is launched, the screen will be unlocked using the
following code in onCreate() method.

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| 
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);

and then the activity is gone.

I think it is the default sms app in the phone refreshed the widget on
home screen and made my activity gone, but my activity is actually
still running.

I am wondering is there a way to keep my activity visible when the
screen is unlocked using above code??

Thanks for the help.

[android-developers] No audio in emulator (ubuntu 10.10)

[Mik]

Dear all,

I cannot manage to play audio in the android emulator 2.2.
I am using ubuntu 10.10.

I've tried to launch the emulator with the following audio options
(and I tried to use root privileges as well):
-audio oss  - I get a warning for audio not supported, fair enough
-audio esd
-audio alsa

Nothing happens with the latest two: emulator starts and runs ok, but
no audio of any sort is played and even if I try the -verbose mode I
don't see any error in the shell.

Is this due to ubuntu 10.10 using pulseaudio?

Does anyone have any clue?

Thanks,
Mik

Re: [android-developers] Error with DB onUpgrade

[Kostya Vasilyev]

AFAIK, there is nothing special, except:

- onUpgrade may take some time to run
- the tables are not updated until after onUpgrade is done

Are you accessing the database in any way bypassing your SQL open helper?

Is this what you mean by 

At the start of the application ,
i initialize all the databases and access columns from the required
tables


?

If you're relying on SQL open helper and its onUpgrade, then that should 
be the only way you're accessing the database.

No. Actually i am accessing another table from my databases at the

There are two gallery apps in the Android open source project. These
will be on a few devices. Other devices will have vendor-supplied
equivalents.

Re: [android-developers] Re: LVL found to be easy to crack

[Kostya Vasilyev]

The server-side LVL could verify the application signature instead, 
since anyone (pirates) changing the code would have to re-sign the 
package. The signature is (I think) available to Market application on 
the phone, and to the LVL back-end on the server.


Android Market's communication with the server and the application are 
encrypted, and Market is signed with the platform key, which means it 
can't be tampered with.


Don't know if there any vulnerabilities with this (other than rooted 
phones), but then, I don't work for Google and shouldn't discuss 
something I know nothing about :)

I think that an easy way to tamper-proof apk would be:
1) Android Market computes a checksum for the apk when the apk is

2) In the License Response (eg. in one extra), Android Market send

3) The aplication computes the same checsum of itself. If the values
don`t match, just finis()
This could be very easy to do for Android Market developers...

First of all it's much harder to bypass especially if you are dealing
with optimized code and you will have to do it at least twice (for arm
abi and armv7 abi). Event toolchain setup is more complicated.

Re: [android-developers] keep alive xmpp connection

[Kostya Vasilyev]

If this is some kind of instant messaging application, then keeping a 
WakeLock for a long time is probably not a good idea. Your users might 
like messages being delivered instantly, but dismayed that it only lasts 
a few hours.


You might want to schedule a wake-up alarm with AlarmManager, acquire 
locks for a period of time, display a notification, and if the user 
doesn't immediately start reading / responding, let the phone fall back 
to sleep.

[android-developers] Problem With Thread !

[MarcoCanali]

I use thic Code in a Class Of type Service :

class A extends Service {







@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
Log.v(AppointmentFinderService, OnBind the Binder );
return mBinder;
}
@Override
public void onCreate() {

Context context = getBaseContext();

}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
serviceHandler.removeCallbacks(myTask);
serviceHandler = null;
/** Destroy the Thread */
myTask.destroy();
}
@Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
myTask = new Task();
serviceHandler = new Handler();
serviceHandler.postDelayed(myTask, delayMillis);
}





class Task extends Thread{

@Override
public void run() {

  try {

sleep(timeToSleep);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();

}
}


}
The Service Work in Right mode but the other activity of application
don't respond to command ...from  the sleep command add !!

Someone have an Idea of problem with Thread process, the sleep method
intact the Application main core i think !!!

Re: [android-developers] Error with DB onUpgrade

[Kostya Vasilyev]

No, onUpgrade doesn't delete any data, tables, or databases.

It's just a callback in your code that's called by Android when the 
desired database version doesn't match the existing database version.


Your callback can do whatever it needs to bring the database schema up 
to date - typically, adding columns or tables.


So if your code just does ALTER TABLE ADD COLUMN, you don't need to do 
anything special to preserve existing data.

Re: [android-developers] Error with DB onUpgrade

[Kostya Vasilyev]

Yes, that's what I meant.

Always call getWritableDatabase, and don't call 
SQLiteDatabase.openDatabase - are you, perhaps, somewhere in your code?


In the link you posted, table upgrades are done by renaming the old 
table and creating a new table from scratch, then copying the data. So 
there is the time period when the table doesn't exist. Most likely, this 
is the reason why you're seeing your error.


Since you've said that your code is multithreaded, I think what happens 
is, one thread starts upgrading the database, while another thread 
starts to make queires, or perhaps tries to perform an upgrade as well.


To fix this issue, you need to add thread synchronization around opening 
the database, to avoid concurrent access until the database has been 
fully upgraded.

If you're relying on SQL open helper and its onUpgrade, then that should

[android-developers] Re: Memory Leak with a ListView revisited

[John Gaby]

First, let me say that this is just a very simple sample application
to illustrate the problem.  My real application is far more complex,
but exhibits this same behavior.

What I need to be able to do is to be able to destroy a given page and
then re-create it later.  There are several reasons for this, but one
of the main ones is that I want to free up the memory of a page which
is no longer being actively used.  Then when the user loads that page
again, I simply re-create it.  In Java, of course, there is really no
way (that I know of) to free objects, you simply stop referring to
them and the the garbage collector magically disposes of them at it's
leisure.   The problem is that it is simply NOT doing that for my
GListView objects.

I realize that this application doesn't represent something that you
might actually do, but the fact is that if you take this program and
run it, the GListView objects are NEVER freed, causing a memory leak.
This is what I am trying to address.  If I can understand why this is
happening in this simple case, I might be able to figure out how to
fix it in my actual program.

Thanks.

 Why are you calling your CreateLayout twice in onCreate?  And even
 worse, why are you calling it at all in an your onClick handler?

 Always call getWritableDatabase, and don't call SQLiteDatabase.openDatabase
 - are you, perhaps, somewhere in your code?

 In the link you posted, table upgrades are done by renaming the old table
 and creating a new table from scratch, then copying the data. So there is
 the time period when the table doesn't exist. Most likely, this is the
 reason why you're seeing your error.

 Since you've said that your code is multithreaded, I think what happens is,
 one thread starts upgrading the database, while another thread starts to
 make queires, or perhaps tries to perform an upgrade as well.

 To fix this issue, you need to add thread synchronization around opening the
 database, to avoid concurrent access until the database has been fully
 upgraded.

Re: [android-developers] Re: LVL found to be easy to crack

[Leigh McRae]

I don't think that you will ever have a solution that will prevent the 
pirates from stealing.  The question is, does LVL prevent the average 
person from being able to steal the app?


For example, on some stores someone can simply forward the email with 
the download link to the app they just purchased to one or more 
friends.  That is really easy for people to do.  I added a simple 
license check to stop this kind of stealing.  I'm sure hardcore pirates 
could steal my apps but at least I have prevented the common case that 
just about everyone can figure out.


Unfortunately I'm not a big Android expert so I don't know how easy it 
is to even copy an app on Android.  Does the average person have the 
means share/steal an app they purchased off the market if it doesn't use 
LVL?


On 10/22/2010 8:49 AM, Kostya Vasilyev wrote:
The server-side LVL could verify the application signature instead, 
since anyone (pirates) changing the code would have to re-sign the 
package. The signature is (I think) available to Market application on 
the phone, and to the LVL back-end on the server.


Android Market's communication with the server and the application are 
encrypted, and Market is signed with the platform key, which means it 
can't be tampered with.


Don't know if there any vulnerabilities with this (other than rooted 
phones), but then, I don't work for Google and shouldn't discuss 
something I know nothing about :)

[android-developers] emulator/ host network setup problems

[chcat]

I am trying to test some udp networking between emulator and host and
I have a problem with setup.
I assigned address 10.0.2.14 to the host interface with 10.0.2.1 as
gateway.. Can't ping 10.0.2.15 from my host, neither can i ping
10.0.2.14 from emulator. Ping from emulator to 10.0.2.2 works fine - I
can capture that ICMP traffic on the loopback interface of my host, so
ICMP works, but how can i create traffic from the host to emulator?
Can someone point me how to make it work?
Note: firewall on my host is disabled.

[android-developers] Re: emulator/ host network setup problems

[Chris Stratton]

For emulator to computer (and outside world) see:

http://developer.android.com/guide/developing/tools/emulator.html#emulatornetworking

To talk from the computer to the emulator you should set up a port
forward and connect to the forwarded port on the development machine's
loopback IP - the emulator does not create a dummy network interface
in the hosting machine that can be accessed by ip address in the way
that virtualbox/vmware/etc often do.

The only way something like LVL will hold up in the long run is if the

A patched and pirated application would likely have no interaction

Or are you suggesting that future devices should only be able to

the phone number.  So it still doesn't help you determine when the
other person answers.  There is nothing in the public API that can be
used to tell you when the phone is answered.  I was hoping someone
knew another way.  Maybe using reflection to get to a hidden method,
or having the program check the system logs for a message that appears
when the phone is answered.

[android-developers] Re: App comment spam

 I've noticed that a lot of comments on top apps are from comment

 virtually every top app with comment spam. My app is getting hit every

[android-developers] Android memory problem + Surface holder problem (surfaceview game)

[GDA]

Hi.

there are 2 ways to let user press home and return back with their
status correct :

1.

public gameView(Context context, AttributeSet attrs) {
super(context, attrs);
SurfaceHolder holder = getHolder();
holder.addCallback(this);
thread = new gameThread(holder);
}
public void surfaceCreated(SurfaceHolder holder)
{
if (!thread.isAlive())
{
thread = new gameThread(holder);
}
thread.start();
thread.runThread = true;
}
public void surfaceDestroyed(SurfaceHolder holder)
{
thread.runThread = false;
boolean fuck = true;
while (fuck)
{
try
{
thread.join();
fuck = false;
}
catch (InterruptedException e)
{
}
}
}
this is the lunarlander based + a bit improved version.

2.

public gameView(Context context, AttributeSet attrs)
{
super(context, attrs);
SurfaceHolder holder = getHolder();
holder.addCallback(this);
}
public void surfaceCreated(SurfaceHolder holder)
{
thread = new gameThread(holder);
thread.start();
thread.runThread = true;
}
public void surfaceDestroyed(SurfaceHolder holder)
{
thread.runThread = false;
boolean fuck = true;
while (fuck)
{
try
{
thread.join();
fuck = false;
}
catch (InterruptedException e)
{
}
}
}
EITHER WAY can't let me insert this code in my thread constructor:

Bitmap land = Bitmap.createBitmap(2000, 2000,
Bitmap.Config.ARGB_);
I know it is way too big. But even If I turn it smaller like

mapland = Bitmap.createBitmap(1000, 1000, Bitmap.Config.ARGB_);
The activity still crush after 3 times of home and return.

I have added this line to the modified lunarlander and the famous
RockScissorsPaper tutorial to test, they all crashed.

I don't understand this : Didn't I release memory since thread.join()
was called??

I really need this bitmap for my application and I want to access it
in my thread, does anyone have any idea ??

Thanks if there are any clues or suggestions, I would be very glad and
thankful.

Re: [android-developers] Android app with a lot of videos

It's not. There's some threshold limit based on someone's post in the
Android Help Forum, though I don't remember what it was.


 Is there a way to specify resources in your Android project that will not
 be stored in the application space but instead stored on the sdcard?


Don't think so, but regardless the user would have to have the space (and
time to download such a behemoth) to install it to begin with. Very few
people are going to be willing to download a 600 MB app. Hell, people
complain about anything over 1MB.


Do the background download as you already suggested, perhaps giving the user
the option to choose what they want to download. Even with an SD card, 600
MB is a ridiculous amount of space for a single app to require on a mobile
device.

[android-developers] Re: Keyboard log for reference

[Bret Foreman]

This sounds like a security problem, since your kb app could pick up
passwords and everything else the user typed. You could do this easily
within your own app, though, by overriding the onKeyDown methods in
the appropriate widgets.

[android-developers] IntentService and Threads

[Eric Carman]

We are in the process of refitting some of our recievers and services
with IntentServices (mostly to address rare ANR issues - and because
IntentService is pretty cool...). In one case we are converting a
traditional service to an IntentService. The original service fired
off a few methods whose job was to download data from our servers.
Each of these requests would spawn a thread of their own to do the
work (apparently not fast enough to avoid the occasional ANR). So now
we have a question concerning the life cycle of these processes.

For example, the following situation demonstrates what is happening:

- Start Intent Service
  - Trigger Download1
  - Download 1 thread starts
- End Intent Service

- Download 1 thread continues.
- Download 1 thread ends

Our question concerns our exposure to the OS shutting down the
Download 1 thread because the Intent Service has terminated before it
finishes up. Not sure if it is becomes more or less likely that the OS
will view it as something that can be flushed.

If the Download 1 thread is more likely to be flushed by OS we will
need to take a different approach.

Thank you.

[android-developers] How to start a background service on install

[klavin]

I have an app which runs as a background service only. I'l like it to
start up when its installed.
As its just a background service it doesnt show up on the pane of
installed apps. So there is no way for the user to manually start it.
I've already regietered for the BOOT_COMPLETED intent which works but
I dont want the user to have to power off the phone after the app has
been installed, just so as they can start it.

I've looked at the following intents: ACTION_PACKAGE_ADDED/CHANGED/
REPLACED/RESTARTED/INSTALL, ACTION_SCREEN_ON/OFF, ACTION_USER_PRESENT,
ACTION_TIME_TICK,
but it doesnt seem that you can register to listen for them from my
manifest.

Any idea how I can start my background service without a power off/on?
Thanks

IntentService already uses a background thread. Either do not fork one
of your own, or do not use IntentService, but rather use your own
thread pool (or just AsyncTask, which has a thread pool) in a regular
Service.

Re: [android-developers] Inflate layouts with different density

How do you know (in Java) which of the three densities Android has 
chosen. Is there a setting in the layout or somewhere that can be checked?

I'm wondering if it is possible to inflate a layout using a different
density value than the default system density.

I have a high density layout, which looks good on the Galaxy Tab
(1024x600px, hdpi) and I like to use the same layout on another tablet
with the same pixel resolution but medium density. The mdpi layout
which is used works on the device but the screen just looks really
empty and I would prefer to scale things up.

So is there a xml argument for scaling the layout, maybe something
similar to Bitmap.Options.targetDensity.
Or could this be done with a new LayoutInflater class?

Thanks

Weeds,

You cannot scale layout.
I am not even sure what would that mean?
Layout is resolution independent anyway.

I think that you would you like for your UI elements to occupy bigger
or smaller proportion of the screen,
As you know, Android 'knows' the density of the platform it sits on
and this gets classified into 1 of 3 brackets.

Since your 2nd tablet has medium screen density, all you have to do,
is to provide a mdpi layout that reflects your desired UI sizes and
proportions.
In other words, simply go and modify your current mdpi layout to make
it 'less empty'.
And don't forget that images used in your layouts have to be scaled as
well in order to achieve the best results.

That is not supported. Please let the user choose when to start up
your application.

 As its just a background service it doesnt show up on the pane of
 installed apps.

That is an invitation to a whole lot of one-star ratings on the
Market. By most reports, users do not like installing which have no
icons in the launcher.

 So there is no way for the user to manually start it.

Then add an activity that adds value to your application, and along
the way sets up the alarm for AlarmManager for your periodic
background work. For example, you could allow the user to change the
frequency of the background work (including never) in the form of a
PreferenceActivity.

Re: [android-developers] [BUG?] Images from drawable-nodpi getting scaled

[Kostya Vasilyev]

If you don't specify supports-screens or minSdk, then your app will 
run in compatibility mode, meaning that it's given an HVGA (240x320) 
virtual screen, which is then scaled as a whole. So your images will 
be scaled.


If you specify minSdk = 4, or supports-screens, then scaling should 
work as expected.


Except one case - if you're running on 1.5.

Since 1.5 didn't have support for multiple resolutions, it doesn't 
understand alternative resource qualifiers and might occasionally grab 
the wrong image. To prevent this, add -v4 at the end of your qualified 
resource directory names, e.g. drawable-hdpi-v4, drawable-ldpi-v4. 
This makes those directories invisible to 1.5.

Be careful here ... target SDK is NOT the same as minSDK. Was that a

The new project now usesuses-sdk android:minSdkVersion=8 /  in the
manifest.

So you're app is designed to work ONLY on 2.2 (SDK 8) or is that what your
target (what you're testing on) is?


Why is this happening? How can I load them without scaling while still
declaring the minimum SDK?

This I don't know - I haven't had to deal with all this screen support stuff
as the defaults work out fine for me for now, but I would double check you
really want min SDK to 8 and read over this:

  In particular, I am seeing it when I try to invoke the HTTPGet in a

  error. The Catch block does fire when this occurs...however, when I
  check my general Exception object, the object is NULL (NULL Pointer).
  Why would this happen if the catch is grabbing the exception?

  My exceptions used to be workingand I was able to see the stack

  Exception class I am using. Can someone please help me understand what
  the heck is wrong with Eclipse, Android, or both? Is there something I

  Mind you, I have already used Stack Overflow for this question. It has
