[android-developers] Android Notification
I've got an application that needs to show a notification of certain events in a day, depending on the event. I know how to do it, if I need a service to stay running in the background, or it will run in the background getting these events on certain days. 2 questions are: 1 - to notify of a new event, you need a service or application running in the background already resolved. 2 - how do I check daily if today's date is equal to an event. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Clickable elements on widget
Hi! Is there a way to have clickable elements inside a widget? (for instance, to change some text when an image is clicked) AFAIK, widgets only use setOnClickPendingIntent() that detects a click on all of the widget, it's not possible to set a method for a single element.

[android-developers] TabWidget NullPointerException in pre-Froyo

[android-developers] Waking the screen after PARTIAL_WAKE_LOCK
I've done an app that must work in the background fetching messages
from a web site that must never sleep. For that I'm using
PARTIAL_WAKE_LOCK, let the screen turn off and wake it when there is a
new message. Here's some code:
--
public void onCreate(Bundle savedInstanceState) {
pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK |
PowerManager.ACQUIRE_CAUSES_WAKEUP screenOff);
wl.acquire();
// on the URL reading method:
while ((line = reader.readLine()) != null) {
if (!pm.isScreenOn()) { // There is a message, turn the screen
on
pm.userActivity(SystemClock.uptimeMillis(), false);
Log.i(TAG,Screen on);
... do stuff
--
This has two problems:
1) The screen doesn't turn on, as expected (although the code is run,
including the Log.i)
2) How to prevent the appearance of the default lock screen? That is,
how can it jump directly to my app after the screens turns off and the
users touches a button or the screen?
I've tried to (re)acquire the wakelock to turn the screen on but that
doesn't work.
Thanks in advance!

Not if you are using PARTIAL_WAKE_LOCK. You need a FULL_WAKE_LOCK.

I'm starting to think PARTIAL_WAKE_LOCK won't work and I'll have to use timers to turn screen off by releasing a FULL_WAKE_LOCK.

[android-developers] Re: Always-on GPS: widget or app?
Just to clarify one thing: you don't want to use the requestLocationUpdates(). I suppose you meant: you don't want to call requestLocationUpdates() for continuous updates, right?In the BroadcastReceiver activity, I'll call the requestLocationUpdates() and then removeUpdate() as soon as there is a fix. Also, the new alarm will be created only after a fix so that there isn't a possibility of alarm conflict (one alarm is not done with the GPS and then there's a new one). -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Always-on GPS: widget or app?
I need to make an app that transmits GPS information each 5 minutes (the information gathering can be switched on and off in the app). The question is: to ensure that the information is gathered should I call the requestLocationUpdates() on an regular app or should I use a widget running in the background? The problem with a regular app is that it will be paused if there's a low memory situation. That would stop the GPS updates, making the app useless. (Correct if I'm wrong) If I use a widget instead, I'm certain it will be started each 5 minutes and requestLocationUpdates() will be called (with a removeUpdate() every time there's a fix). But can I be certain the widget will stay in memory until there's a GPS fix? Or, if the GPS fix takes too long, there is also the risk that the widget will be paused before acquiring a fix? Comments by anyone with field experience on the subject will be most welcome, thanks :) -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] ViewFlipper with arbitrary number of Views
Hi! I'm developing a simple photo gallery application that pulls files from the Net and uses a ViewFlipper to change Views. Since I don't know how many Views the ViewFlipper will have, I have to add all the views in code and not in XML. My question is: are all the Views of the ViewFlipper loaded in RAM? If I use, fo instance, a gallery with 100 or even 1000 photos with 320x480, will I run the risk of running out of memory or is Android smart enough to and fetch and drop Views from memory as needed? The alternative is the use a ViewFlipper with just 3 views (current, previous and next) and load photos as needed but it is a cumbersome process.

[android-developers] Re: Adding a contact without a READ_CONTACTS permission
That only tells you about stuff you are doing. Which can't be kept in sync with what is actually in the database, and doesn't prevent you from colliding with anything already in there. Duplicate contacts aren't that much of a nuisance, imho. They're easy to fix and prevent. Specially if you consider the other option is adding another permission, going against Google's own best practices that we should use the least permissions possible. What is it that you are actually trying to do here? Consider, por instance, a database of contacts of sports clubs. Put them in a map and let the user choose to add a contact for the local club by adding a button. The app stores the addition and warns the user if he tries again to add the same contact. This is NOT blindly stuffing a contact, as you said, it is a normal response to a user action. If writing a contact is and will be impossible without the READ_CONTACT Google should at least assume READ_CONTACT after adding WRITE_CONTACT in the manifest.xml. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Adding a contact without a READ_CONTACTS permission
all, it seems Google was more concerned about someone reading your contacts to get your private information than they were about a malicious program writing bogus values to your contacts (though I can see that as an attack vector too). Exactly, BOTH are attack vectors so it should be possible to read w/o writing and vice-versa. Having said that, it's potentially more harmful to read contacts than to write them. The later could be easily fixed afterwards but the former could be big problem - think of a program that sends all of your contacts to a web site. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Adding a contact without a READ_CONTACTS permission
Btw, if you are writing an application that is blindly stuffing contacts into the contact provider without looking at what is currently there... I think this is fairly fundamentally flawed to start with. I beg to differ. If the application is well-made you'll get at least an warning that a contact was already added. For me, this is way better than requiring an app. to have permission to read when all it wants is to write contacts. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Adding a contact without a READ_CONTACTS permission
it would have to READ the contacts first. How would it possibly know it was a duplicate otherwise? Easy, use the SharedPreferences to store the contacts the user added.

It is very hard to ensure that someone with write access can't also get data back from the provider, so generally no. It's a bit lame, imho.

[android-developers] Detecting activity' fresh start
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!

[android-developers] MapOverlay turns the phone unresponsive
I'm trying to draw some points (around 200) in a MapOverlay and
noticed that the application gets slow and the phone becomes
unresponsive. Here's my code:
MapOverlay mapOverlay = new MapOverlay();
ListOverlay listOfOverlays = mapa.getOverlays();
listOfOverlays.clear();
listOfOverlays.add(mapOverlay);
...
class MapOverlay extends com.google.android.maps.Overlay
{
Cursor c;
Bitmap bmp;
private MapOverlay()
{
...initialize Bitmap and then Cursor with around 200 points taken
from a database...
}
@Override
public boolean draw(Canvas canvas, MapView mapView,boolean shadow,
long when)
{
super.draw(canvas, mapView, shadow);
for (int f=0;fc.getcount();f++) {
c.moveToPosition(f);
Point pt=new Point();
mapView.getProjection().toPixels(new
GeoPoint(c.getInt(0),c.getInt(1)),pt);
canvas.drawBitmap(bmp, pt.x,pt.y-16, null);
Log.i(TAG,Drawing point +f);
}
...
After adding the Log.i message I found the problem, the loop is run
endlessly (note that the phone is quiet and there's nothing happening
in the background):
I/XP (10507): Drawing point 0
I/XP (10507): Drawing point 1
...
I/XP (10507): Drawing point 199
I/XP (10507): Drawing point 0
I/XP (10507): Drawing point 1
...
I/XP (10507): Drawing point 199
Is this a normal behaviour, a bug in the OS or am I doing something
wrong?

[android-developers] Re: MapOverlay turns the phone unresponsive
Any reason you're not using an ItemizedOverlay? Afaik, ItemizedOverlay only supports one marker type, right? I want to be able to use several. Of course I could use several ItemizedOverlays, each with it's own marker, but I guess that will impact perfomance. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: MapOverlay turns the phone unresponsive
Thanks, Mark!
Strangely, I can't seem to make your code work.
If I use:
public MyItemOverlay() {
super(null);
... the rest of your code...
It crashes with NullPointer in:
@Override public void draw(Canvas canvas, MapView mapView,boolean
shadow) {
super.draw(canvas, mapView, shadow);
}
But it works somewhat if we change the constructor to:
public MyItemOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
Unfortunately, it only shows the defaultMarker, despite the use of the
CustomItem with other Drawables.
Maybe this feature is deprecated? Or the behaviour of ItemOverlay's
super() has changed?

[android-developers] missing Lists.newArrayList()
I was trying to delete a contact using the code in the docs:

ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
.withSelection(Data._ID + =?, new String[]
{String.valueOf(dataId)})
.build());
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
But Eclipse doesn't how to find Lists. What import statement do I
need?
Also, is there a more direct way to delete a contact? Thanks in

[android-developers] ContactsContract and target version
Hi! I'm creating an app that needs to create a contact. My 1st attempt was: ContentValues values = new ContentValues(); values.put(Contacts.People.NAME, Name); values.put(People.Phones.TYPE, People.Phones.TYPE_MOBILE); values.put(People.Phones.NUMBER, +1); Uri myUri = getContentResolver().insert(People.CONTENT_URI,values); This creates an exception: column NUMBER is invalid (huh?) It seems People.Phones.NUMBER is deprecated so I tried to use ContactsContract. Unfornately ContactsContract and RawContacts are not resolved (using Eclipse) unless... I change the project target to 7. Since I need the app to run on target 3 (1.5), could please someone tell me how to add a contact - that works on always versions?

[android-developers] Re: Scrollview doesn't like a complex child?
Thanks for your help, Romain. What is the correct way to show a (non-scrollable) footer below a Scrollview?

Opsie, it seems the problem is that the scrollview is inside a framelayout because I have navigation buttons at the bottom of the screen. Non-scrollable, of course.

[android-developers] ViewFlipper with just one View
Hi! I'm planning on creating an app with a news page with image, title, content, etc. The flip animations used in most ViewFlipper applications are great but have one problem: only work with a ViewFlipper with a determinate number of view (in my case, I don't know how many news there are). The only solution I found is to duplicate the View, prepare the contents off-screen then call ViewFlipper's showNext() when the Next button is pressed. This is a cumbersome and wasteful.

[android-developers] Passsing a Cursor to a Activity
Hi!
Since Intent.putextra doesn't accept Cursor, what is the alternative
to pass a complex structure to a class?
For instance:
Cursor c; // assigned elsewhere
...
Intent myIntent = new Intent(this, my.class);
myIntent.putExtra(mycursor, c); // this won't work :-(
startActivity(myIntent);
... in my.java:
public my my extends Activity {
...
If the cursor is very complex, it will be a pain to mention each and
every item using putExtra (and then again in the receiving Activity).
Thanks in advance!

[android-developers] Change item in Listview after clicking
Hi!
I've created a rather complex layout for listview rows where only the
first line is visible (the rest use android:visibility=hidden).
When an item is selected, I want all the invisible objects to appear
(selected.setVisibility(1)) - checking first if I have to hide again
the previous selection.
Here's the (simplified) code:
private TextView selected=null;
...
public void onListItemClick(ListView parent, View v,int position, long
id) {
if (selected!=null) {
selected.setVisibility(0);
}
selected = (TextView) findViewById(R.id.text2); // text2 is an
invisible object that I want to show
selected.setVisibility(1);
}
The problem is that this only retrieves the invisible items in the
first Listview row.
What's the way to access ListView rows and change 'em?
Thanks in advance!

[android-developers] Re: Change item in Listview after clicking
Gotcha! Thanks, Mark!
Unfortunately, it solves half the problem. When clicked, the hidden
objects appear but the older selection doesn't disappear:
private int selection=-1;
...
public void onListItemClick(ListView parent, View v,int position,
long id) {
TextView tv;
View linha;
if (selection!=-1) {
linha=(View) parent.getChildAt(selection);
tv = (TextView) linha.findViewById(R.id.text2);
tv.setVisibility(0);
linha.postInvalidate();
}
linha=parent.getChildAt(position);
tv = (TextView) linha.findViewById(R.id.text2);
tv.setVisibility(1);
selection=position;
...
Anyway, it seems I'll have to rethink my list since objects defined as
invisible in the layout nevertheless occupy screen space (!). I'll
have to create dinamically in my Java class.

[android-developers] Two-level tab navigation
