[android-developers] Re: Confused about Timezones and Sqlite3

[Sarwar Erfan]

Hi,
Conversion is a Java question, not related to Android though.

Anyways, here is a catch --- in Java, the date is ALWAYS stored as UTC
in "Date" object. You CANNOT convert its timezone (stored value will
be always in UTC).
However, you can print it in different timezones, that is here
formatters come in.

EXAMPLE:
//
String dateStr = "8-8-2010 11:00 AM EST";
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-
hh:mm a zzz");
try {
Date d = formatter.parse(dateStr);
System.out.println(d.toGMTString());

} catch (Exception e) {
e.printStackTrace();
}
//==


Now, System.out.println(d.toGMTString()); --- this will output:
8 Aug 2010 16:00:00 GMT
Which is correct (as I came to know that EST is GMT-5)


If you want to do some more on date and time in Java, then you better
ask in Java language related groups.


Regards
Sarwar Erfan

[android-developers] Re: Yet another Droid OpenGL texture problem

[Mike]

Well that wasn't it but you were on the right path. It is something to
do with my texture selection. I took a break down at the local pub and
after a few beers I saw much clearer. :)

I'll post an update sometime tomorrow after I get everything nailed
down completely. Thanks everyone for the help.

[android-developers] Re: How to know the home launcher app packagename through programming?

[manoj]

I am getting the correct result if I have the only one home app
(default home) is installed. If i have more than 1 home apps, I am
getting the result w.r.t ResolveActivity. Now how can I resolve this?

say, for example,
1. Android Home (action=MAIN, cat=LAUNCHER,HOME...etc).
2. MyHome(action=MAIN, cat = LAUNCHER,HOME...etc).

current home set is MyHome.

Now If I follow the above code, the result displayed is
ResolverActivity. Now how can I resolve this.

Thanks,
Manoj.

[android-developers] Re: on sdcard, File.canRead() = true, File.canWrite() = false

[Bob Kerns]

Ah, yes, of course. That critical fact slipped my mind -- thanks
Dianne!

This is, of course, a major reason why ability to write to the SD card
is controlled by an application permission.

Even without the limitations of FAT, file ownership is a tenuous
concept with removable media. I have scripts to set up EC2 instances,
and I have to force user UIDs in each created, so that the filesystems
I mount on those instances can be consistent. And that's using the
ext3 filesystem.

[android-developers] Re: how to get the screen size in inches...

[Rob]

Hopefully, when they fix the Droid it won't report 240.  That's what
the emulator reports with a screen size of 3.7 (diagonal) and
WVGA854.  I tried 240 on my Droid, and it's definitely not as accurate
as 264.  At 240 pixels/inch, the Droid would have a 2 inch wide
screen.  The actual width is 1.8 inches.

[android-developers] Re: Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE

[William Ferguson]

I can't imagine why you care whether its on an external storage card
embedded or inserted in the phone versus inside the platform storage
space.
As far as your app in concerned it is irrelevant.

If you are worried about security of your images then excrypt them.

Chances are you can google for ways to convert text to date data types.

The user can either enter an address and your app can geocode it or
the user can tap on the map and your app can get the lat long

[android-developers] Re: How to handle OutofMemoryError in a service?

[Soumya]

I would investigate the "root cause" of out of memory error instead of
finding a way to restart your service/activity.

[android-developers] Re: Yet another Droid OpenGL texture problem

[Robert Green]

Heh, I think I see your problem.

Replace  this.textureMap.put(new Integer(textureFiles[i]), new
Integer(i));
With  this.textureMap.put(new Integer(textureFiles[i]), new
Integer(tmp_tex[i]));

Droids don't number textures incrementally like qualcomms do.  It was
working because your texture ids happened to align with i.

[android-developers] Re: how to get the screen size in inches...

[Rob]

Thanks, Mark.  That seems to work.  I'm using this:

float pixels_per_X_inch = displayMetrics.xdpi;
float pixels_per_Y_inch = displayMetrics.ydpi;

if(Build.DEVICE.equals("sholes") && Build.MODEL.equals("Droid"))
{
pixels_per_X_inch = 264; // 480/(9*3.7/sqrt(337)) = 264.613474
pixels_per_Y_inch = 264; // 854/(16*3.7/sqrt(337)) = 264.820203
}

The 3.7 is the diagonal of the screen in inches (from the device
specification).  It's supposed to be a 16:9 display with a resolution
of 480x854.  If somebody knows for certain what the device should
return for the xdpi/ydpi, please, post it.  I'm sure that 3.7 inches
is not exact, so maybe I'm off by a few pixels, but for sizing my
tiles to 1 cm it works quite well.

[android-developers] Microsphone cannot be recorded on android emulator

[aftershock]

Hi,


A small program that I wrote cannot record the microphone. One api
call, getminbuffersize keeps returning -2 which is not correct. The
program works on a real android one.

I use 11025Hz, 16bit pcm,mono recording..
Can you give me a suggestion what can be wrong?

Thank you.

Why do you set GL_TEXTURE_MIN_FILTER twice? Replace one of the calls
with GL_TEXTURE_MAG_FILTER.

[android-developers] Re: Confused about Timezones and Sqlite3

[Bara]

Ahh, that makes a lot more sense.

Now, when you say "always use UTC" (which makes more sense to me), how
exactly would I convert a time to a different timezone?  In my
original question I asked "How would I go about converting a string

11:00 AM EST" into the proper format for sqlite3?"  Can you provide
some sample code or a page that would show how to do this?

I come from a .NET background and usually dealing with datetime stuff
is simple, so excuse me for asking so many questions :)

[android-developers] Do we need to call System.gc() ?

[Alex Xin]

Hi,

Do we need to call System.gc() to indicate that system should do a garbage
collection or just let system to choose when to collect garbage and free it?

Because my app will random FCs on certain phones, but if I add some calls to
System.gc(), then there were no FCs.

Thanks & BRs,

Alex

Re: [android-developers] Opening a context menu in the onCreate of an activity

[Chris Stewart]

I should also say that I'm kind of searching for a best practice here as
well.  I get the vibe that opening the context menu in this way may not be
the most sound way of doing it, but hey, if it works and it's not
troublesome for the user, that works for me.

Re: [android-developers] How to set data in google maps and further access that data

Sorry may be I am not clear to you, actually suppose a client want to set
the location of a place in the app's map then does he need to know the
geocode or he can directly set it in the map only.
thanks for all your help and assistance.

Re: [android-developers] Opening a context menu in the onCreate of an activity

I have tried variations of that but getting the View is where I'm falling
short.  Something like:

registerForContextMenu(this.getCurrentFocus());
openContextMenu(this.getCurrentFocus());

I'm not sure what View I should be passing in as right now this Activity
doesn't really have any UI components laid out in the XML file.

[android-developers] Re: Has anyone gotten Point Sprites to work?

[iconnary]

Ok, good to know that they are supported.   The Galaxy wallpaper even
runs on my phone.

Are there any source code examples showing how to use point sprites in
Android?  I've found a number of helpful iPhone sample projects
demonstrating GL_POINT_SPRITE_OES and GL_POINT_SIZE_ARRAY_OES usage,
but they all throw UnsupportedOperationException when I duplicate them
in Android.

Specifically, the call to glPointSizePointerOES is where things go off
into the weeds.  I call
glEnableClientState(GL11.GL_POINT_SIZE_ARRAY_OES), then
glPointSizePointerOES(), and the exception is thrown.   If I disable
GL_POINT_SIZE_ARRAY_OES and just call glPointSizef/x, then the entire
GL driver .so dumps core, and with no useful error.

Thanks
Iven

[android-developers] Re: AsyncTask and UI activity

[Bob Kerns]

I recommend you display a great big message saying "do not disturb!"
while the restore occurs. You can't actually block the user, for
example, from the home key, or the power key...

So I'd suggest transactionalizing things as much as possible. Read a
set of related files (e.g. for one app) all at once to temporary
names, then
quickly rename the old ones, rename the temporary ones with their
permanent names, and delete the old.

Then, if you receive a Pause event, delete your temporary files.

If you ever encounter renamed old files, you have a partial update.
That should be very rare, but you can roll back by restoring the old
files to their original names, deleting any new files in their place
-- or renaming them to a recovery name inn case the application has
done something with the partial update in the meantime.

You can minimize the chances of that by checking for the restore
progress on reboot, and verifying consistency at that point.

[android-developers] Opening a context menu in the onCreate of an activity

[Chris Stewart]

I have a need to capture some user input when an activity opens for the
first time.  I'm hoping to give the user a list of options to select from,
which will be pulled in dynamically.  I'll then store the selected value
locally for future use.  I'm not finding a way to do what I'm after and was
wondering if anyone has run into this before and how they solved it.

Convoluted hacks are basically your option. This really shouldn't matter in
general and I'd recommend you rethink you your app functions.

Giving the user the option to manually refresh while in your activity while
periodically using a Service in the background to refresh otherwise seems
like a better idea IMO.

Re: [android-developers] How to set data in google maps and further access that data

[Frank Weiss]

Thanks for getting down to the brass tacks.

First, that field (aka member) declaration and initialization should
go inside the class declaration, not before it.

Next is Java Generics, a powerful Java language feature that takes
some time getting used to. Here's the official story:
http://www.oracle.com/technetwork/articles/javase/generics-136597.html.

I can summarize how it's applied to HelloItemizedOverlay. The
 notation tells the compiler that you want this list to
only contain instances of OverlayItem (or its subclasses). This helps
to avoid programming errors, because now your code can only add that
type of object and the rest of the Android map API is gauranteed that
the list will only have objects of that type (or subtype). Also note
I'm using the terms type and class interchangably for this discussion.

After the Activity lifecycle, I think the use of Java Generics is the
most difficult concept for Android newbies, so don't feel bad. But do
study these two concepts thoroughly to make your Android development
life easier.

[android-developers] Re: how can I check my app stopped by which home key or other apps

[optimusgeek]

Thank you all.
Here is what I'm doing.
I'd like to register a notification as 'ongoing' when my app being
invisible by only Home key.
but on second thought, It's meaningless as your opinions.
There's not different one app between home screen from application
aspect.
I do not notice that It's all about home key eventually...
and I know I can't control home key.
I think it's unnecessary worry.

thanks guys.

[android-developers] Re: Yet another Droid OpenGL texture problem

[Mike]

Welp, I did even better. I went out and bought a Droid from
Craigslist.

I logged the height and width of the bitmaps at each of the mipmap
levels and here's the output:

DEBUG/Texture(1558): Texture image loaded at 256 x 256
DEBUG/MMTexture(1558): Texture image loaded at 128 x 128
DEBUG/MMTexture(1558): Texture image loaded at 64 x 64
DEBUG/MMTexture(1558): Texture image loaded at 32 x 32
DEBUG/MMTexture(1558): Texture image loaded at 16 x 16
DEBUG/MMTexture(1558): Texture image loaded at 8 x 8
DEBUG/MMTexture(1558): Texture image loaded at 4 x 4
DEBUG/MMTexture(1558): Texture image loaded at 2 x 2
DEBUG/MMTexture(1558): Texture image loaded at 1 x 1


So, if it's not the size that's the problem, something with the format
of the bitmaps themselves? Well at least now I have a phone to test
on.

Re: [android-developers] How to handle OutofMemoryError in a service?

[Jenus Dong]

Service is bound to acrtivity, this kind of service you can control. So if
service has encounted an OutofMemoryError, the OS could restart your
activity, you can restart your service in the activity, eg, OnCreate,
OnRestart.

Re: [android-developers] How to set data in google maps and further access that data

[Anthon Bob]

This part:

Part 2: Adding Overlay Item

I'll elaborate. first of all, they say to put this line "private
ArrayList mOverlays = new ArrayList();" before
HelloItemizedOverlay class. I did that. Is something supposed to go into
 parameter or is it supposed to say like that?

Secondly, mOverlays is giving an error (red lined)

By the way, thanks again. I appreciate it!

[android-developers] Re: Yet another Droid OpenGL texture problem

[String]

Can I suggest you stick a Log call in with your actual loaded texture
sizes? Something like the following:

Log.i(TAG, "Texture image loaded at " + mapImage.getWidth() + " x
" + mapImage.getHeight());

Then get one of the Droid/Milestone users to shoot you a logcat
output... xda-devs folks ought to be able to handle that. That'll at
least tell you if the images are loading at the size you expect, or if
it's a different problem.

[android-developers] How to determine that an activity was brought to the foreground from the home screen vs. another activity

[jsera]

So I'm writing a news app that has to periodically refresh it's
database of articles.

I want to refresh after a certain amount of time has passed. I could
check in the onStart of every activity, but then I'd wind up
refreshing, and preventing user interaction in the middle of an app
"session".

If I need to refresh, I'd like to refresh when coming back from the
home screen, but I don't want to refresh when coming back from another
activity within the same app. Other than some convoluted hacks, I
don't know how to make this determination.

Is that on HTC's Sense UI? If so, their widgets are "baked in" to the
home screen and don't have to follow the same rules as the rest of
us.

Mark's right, you need to supply multiple providers, one for each
size. Not a great UX, but that's how it works.

[Doug]

In case people don't know this, you can create a "product web site"
with facebook that you don't have to be a facebook member to see.  You
do have to have a facebook account yourself, and if someone wants to
post or discuss, they have to have accounts.  It's a perfectly usable
place to share general information about your product.

[android-developers] Re: Yet another Droid OpenGL texture problem

[Robert Green]

Let me add that when mipmapping, the textures must not only be power-
of-two but also square, meaning 256x256, not 128x256 like you can
normally do.

[android-developers] Re: POJO junit test in an Android project

[doug]

Oh well, It doesn't seem that the Eclipse plug-in would even run a
test case subclassed directly from junit.framework.TestCase.  How do
folks test POJOs in Android then?

Thanks,

[android-developers] How to handle OutofMemoryError in a service?

[doug]

Hello,

If my service encounters an OutofMemoryError when creating new
objects, what can I do to tell Android to restart my service later?  I
thought about Alarm but then I can't create a pending intent in the
OutofMemoryError situation...

Thanks,

I've never seen that. You may be confusing "do not block the UI thread"
which is a different matter.

Try using:

instead.

Re: [android-developers] Re: Error after publishing

[Kwan Cheng]

This is a tricky error.  I've seen this a lot on my own programs.

There is no way to help you unless the source  is available.  Try to  run
the program in debug mode on the device.  It will usually break at the point
of the null pointer exception.

It is most likely because the acidity thread got executed before you had a
chance to initialize the object that is being used.

[android-developers] Webview of local webpage shows cluttered/repeated text

[jb]

Hi,

I display a local webpage (located in my 'assets' directory) within a
Webview. The webpage is almost exclusively text.
When displayed, the middle third of the body of text appears to be
repeated multiple times, and makes the text appear very cluttered.

I ran the webpage through the W3C html validator and it passed without
any errors.

Displaying it on regular browsers work perfectly.

Here's my code:

setContentView(R.layout.signpost);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setBackgroundColor(0); // make the background transparent
mWebView.setBackgroundResource(R.drawable.background);
InputStreamReader is = null;
try {
is = new
InputStreamReader(getApplicationContext().getAssets().open("signPostContent.html"));
BufferedReader buff = new BufferedReader(is, 8192);
StringBuffer out = new StringBuffer();
String strLine = null;
while ((strLine = buff.readLine()) != null) {
out.append(strLine);
}
is.close();
String mimeType = "text/html";
String encoding = "utf-8";
String fin = new String(out.toString());
mWebView.loadDataWithBaseURL("file:///sdcard/data/data/
com.this.that/", fin, mimeType, encoding, "");
} catch (IOException e) {
e.printStackTrace();
}

Any ideas?

Don't include them with your application.
When the application first starts, if the external storage contains
enough space, download your images and store them there.
For what its worth, I wouldn't download an mobile app that was 30MB,

Re: [android-developers] How to set data in google maps and further access that data

[Anthon Bob]

Is geocode lat/long or the micro degrees? Also, if I have all the geocodes
typed up, how do I utilize that? Do I have to create a new class to create
itemized overlay with arrays?

Re: [android-developers] An alternative for android-market-api

[Shane Isbell]

I'm not aware of any alternative but I've found the API works very well. The
thing is Android Market itself doesn't play nice so you just need to make
sure that your use of the API is robust to failures (sometimes Android
Market logs you out, or throttles you or you gives an invalid result...).

I'm assuming that the data you want to save includes a geocode

Using Shared Preferences, in the onPause method save the data and in

It doesn't do that on my Nexus One. It asks what content I want, but
the size is the same.

[android-developers] Re: Error after publishing

[HIRAK]

This is the stacktrace I received, when I published the app.
Now, nowhere in the stacktrace, my classes are mentioned.
So I am not able to understand, where the code is breaking.
So I thought, if anybody can give me some hint, about how to go
forward with solving this issue.

Re: [android-developers] Re: on sdcard, File.canRead() = true, File.canWrite() = false

[Dianne Hackborn]

You can't change the permissions on stuff in external storage.  That uses a
FAT filesystem, which doesn't have permissions, so all files there simply
immutably use the permissions of the mount point.

Re: [android-developers] Re: is there any API available to receive the broadcast receiver for app started.

[Frank Weiss]

Indicator, I don't understand why you repeat the erroneous "launching
another app". Correct me if I'm wrong, when you tap an icon on the
home screen what's happening is that an intent is being sent which
starts an activity in a particular package. That package's application
context may already be "launched" (such as if an activity in it was
recently used), in which case there's no need to either create a new
process for it, nor to reload the package into a process. "Launching"
an activity only occurs if the Andorid system has garbage collected it
or if it was force closed.

This can be easily demonstrated with the Maps application. The first
time, the tiles take a while to load, subsequently, they are displayed
immediately when bringing it to foreground. After a force close, the
tiles again take a while to load.

[android-developers] Re: Populating custom layout from xml resource.

[gnugu]

Here is the solution. Thank you Mark Murphy for you guidance and for
the excerpt from your book (found on the link you provided above).

The purpose of this exercise is to use ListView for app navigation
instead of a menu.

In /res/layout create menu_list_item.xml:

http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip">









In /res/xml create file main_screen_actions.xml that looks like this:


http://schemas.android.com/apk/res/android";>






Create class:
public class ListMenuDescriptor {
public int iconId;
public String title;
public String summary;

/**
 * Constructor
 *
 * @param iconId Id of the icon resource.
 * @param title Menu item title.
 * @param summary Short menu description.
 */
public ListMenuDescriptor(int iconId, String title, String summary) {
this.iconId = iconId;
this.title = title;
this.summary = summary;
}
}


Create class:
public class ListMenuArrayAdapter extends
ArrayAdapter {
private LayoutInflater _inflater;

/**
 * Item tag for list menu items describing xml resource file.
 */
public static final String ITEM_TAG = "item";
/**
 * Icon resource attribute.
 */
public static final String ICON_ATTR = "icon";
/**

public static final String SUMMARY_ATTR = "summary";

/**

 * @param items
 *List menu items.
 */
public ListMenuArrayAdapter(Context context,
ArrayList items) {
super(context, R.layout.menu_list_item, items);

_inflater = (LayoutInflater) context

.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

/**

 *Id of the resource describing list menu items.

public static ListMenuArrayAdapter createFromResource(Context
context,
int listMenuItemsResId) {

ArrayList items = new
ArrayList();

// inflate and create the list
XmlResourceParser parser = context.getResources().getXml(
listMenuItemsResId);
try {
while (parser.getEventType() != 
XmlResourceParser.END_DOCUMENT) {
if (parser.getEventType() == 
XmlResourceParser.START_TAG) {
String tag = parser.getName();
if (tag.equals(ITEM_TAG)) {
items.add(new
ListMenuDescriptor(parser.getAttributeResourceValue(null, ICON_ATTR,
0),

parser.getAttributeValue(null, TITLE_ATTR),

parser.getAttributeValue(null, SUMMARY_ATTR)));
}
}
parser.next();
}
} catch (XmlPullParserException xpe) {
Log.e(ListMenuArrayAdapter.class.getName(),
Log.getStackTraceString(xpe));
throw new RuntimeException(xpe);
} catch (IOException ioe) {
Log.e(ListMenuArrayAdapter.class.getName(),
Log.getStackTraceString(ioe));
throw new RuntimeException(ioe);
} finally {
parser.close();
}

return new ListMenuArrayAdapter(context, items);
}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;

if (row == null) {
row = _inflater.inflate(R.layout.menu_list_item,

}

ListMenuDescriptor descriptor = this.getItem(position);

TextView txt = (TextView) row.findViewById(R.id.title);

Re: [android-developers] Re: developing with htc aria

[Kostya Vasilyev]

FWIW - I only have experience with an HTC Hero, not Aria. It is necessary to
select HTC Sync *in the phone* for it to connect with the ADB driver. Having
HTC Sync installed in Windows is not necessary, and I suspect might even be
detrimental.

The phone never finds the Sync app in Windows, and displays an error
message, but shows up in adb/Eclipse.

Now, I wonder why there is no special connect mode just for debugging in any
Android phone I've used, and why adb doesn't use a class driver. But I
guess that's like asking who shot Kennedy...

If you can get hold of a computer running Windows 7 or Linux, you
could try testing with that; it is however more likely the specific
drivers for the Aria that are the issue - the core of Windows 7 and
Vista are much the same (Windows Vista = NT6, Windows 7 = NT6.1) so I
do not think the OS is the most likely cause.

call.If I disable textures and comment out the glTexEnvi all, it
throws the same exception further down, at glPointSizePointerOES().

Are point sprites properly supported in Android?   Has anyone gotten
them working?Or is there an issue with my code below?

gl.glEnable(GL11.GL_TEXTURE_2D);
gl.glEnable(GL11.GL_BLEND);
gl.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
gl.glDepthMask(false);
gl.glEnable(GL11.GL_POINT_SPRITE_OES);
gl.glTexEnvi( GL11.GL_POINT_SPRITE_OES, GL11.GL_COORD_REPLACE_OES,
GL11.GL_TRUE );
gl.glEnableClientState(GL11.GL_VERTEX_ARRAY);
gl.glVertexPointer(2, GL11.GL_SHORT, 0, .vertBuffer);
gl.glEnableClientState(GL11.GL_POINT_SIZE_ARRAY_OES);
gl.glPointSizePointerOES(GL11.GL_FLOAT, 0, pointSizeBuffer);





Thanks

[android-developers] AppWidget multiple sizes

[Fernando T]

I'm looking at creating an AppWidget and want to have the user select
which size they want before adding it. Thus, the user can choose 1x1,
2x2, etc. The Calendar widget in Android 2.2 (and possibly earlier,
but not in 1.6) does this. How is this done?

Re: [android-developers] Re: Content provider doubt

[Kostya Vasilyev]

I'd like to further clarify one important benefit of ContentProvider
lifecycle management for an application with multiple Activities that need
to share data.

Putting a database into a Service means that, to use the database, an
Activity needs to bind to the Service. Binding is asynchronous, so there is
going to be a delay between the time an Activity appears on the screen, and
when it can start populating itself with data from the Service's database.

Now, I don't know how long of a delay this turns out to be, perhaps not long
at all, but there certainly is one.

With a ContentProvider, an Activity can start making data queries right
inside onStart or onResume. So the delay inherent in the Service pattern is
not there, and UI should feel more responsive.

But that lifecycle management is a major benefit, since you really
would not want to handle releasing and re-acquiring database
connections etc. all on your own without that support.

ContentProvider also provides consistent means for sharing data
between applications, not just between application components of a
single activity.

The savedInstanceState Bundle passed to you is null the first time through.
It is non-null if you're being restored (from a screen rotation or
otherwise), in which case it contains the data you save in
onSaveInstanceState.

[android-developers] Re: hi, i'm newbie in android, i wonder about float dp...

[Joseph Earl]

Your calculation is wrong, it should be

buttonWidth = (currentDPI/160)*100;

So if currentDPI = 240 then buttonWidth = 150px

Instead of using (currentDPI/160) use
final float scaleDPI =
getContext().getResources().getDisplayMetrics().density;

and then

buttonWidth = scaleDPI*100;

See http://developer.android.com/guide/practices/screens_support.html#support
for more information on the topic.

How you implement it from a UI standpoint is up to you. An activity
with options to back up and restore the data seems like a reasonable
choice, though.

[android-developers] Detecting activity' fresh start

[Pinheiro]

Hi!

How can we detect if an Activity is run for the 1st time? I mean, it's
run just after the user clicked on the icon in the homescreen and not
after some event like screen rotation?

For instance:

public class Incoming extends Activity {
private boolean firstrun=true;

@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);

if (firstrun) {  // This is always run
firstrun=false;
... do some heavy work (import a database from the
web, etc)
}

The variable firstrun is always true. I've tried to change the
firstrun value in onResume but it's called after and not before
onCreate.

Is there a simple way to do this or will I have to resort to capture
screen orientation using onConfigurationChange?

Thanks in advance!

That depends on where you draw your line to decide what is in and

Applications under test inherit from the basic test (TestCase), can't
you get the "black box" test effect you desire?

That's rejecting the BackupManager solution, because it only goes to
Google's servers. There is no other built-in alternative.

server, because I don`t have a server, and also this files cannot go a
server side because they have some information that must be safe.

about this just work in Android 2.2, it`s not a problem

[android-developers] Re: is there any API available to receive the broadcast receiver for app started.

[Indicator Veritatis]

The real solution is: study 
http://developer.android.com/guide/topics/fundamentals.html,
especially the parts on lifecycles of activities, services and
broadcast receivers (http://developer.android.com/guide/topics/
fundamentals.html#lcycles). Then take into account what Dianne said
(that there is no such broadcast). After studying that section, you
will more likely come up with the real solution to your problem. It
may help, for example, to notice that though there is no "app started"
broadcast, you can tell when your own applications/activities lose the
foreground or become invisible. This is almost the same information,
since launching another app is what causes yours to lose foreground
(device going to sleep will do this too). So you may be able to get
close enough by waiting for onPause() and onStop() events, overriding
these methods.
