[android-developers] Bug with Animation on Android?
this is quite difficult to explain, but here we go! Ok, the transition until I get the Fragment where the Animation is placed would be: MainActivity (extends Activity) - loginActivity (extendsActivity) - now I call: Intent homeIntent = new Intent(loginActivity.this, HomeActivity.class);Bundle bundle = new Bundle(); bundle.putSerializable(risposta,(Serializable)risposta); homeIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // read below homeIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK); // read below homeIntent.putExtras(bundle); startActivity(homeIntent); which starts *HomeActivity* which extends *FragmentActivity* and at the end of onCreateView() I add my Fragment *CircleFragment* that @Overrides this on onResume(): RotateAnimation rotateAnimation1 = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotateAnimation1.setInterpolator(new LinearInterpolator()); rotateAnimation1.setDuration(4000); rotateAnimation1.setRepeatCount(Animation.INFINITE); radar.startAnimation(rotateAnimation1); or XML (tried both): ?xml version=1.0 encoding=utf-8?rotate xmlns:android=http://schemas.android.com/apk/res/android; android:fromDegrees=0 android:interpolator=@android:anim/linear_interpolator android:toDegrees=360 android:pivotX=50% android:pivotY=25% android:duration=4000 android:startOffset=0/ *WHAT HAPPENS?* *SOMETIMES* it works bad (sometimes fine!): it starts arround ~(50%, 25%) (or 0.5, 0.25), not exactly (calculated) but if I let the screen go off and I resume it, everything works again :O *WHY IS IT STRANGE?* 1. do you see the two lines commented which cleans the task and start the activity on top ? if I don't set that, everything is OK 2. If I start it as MainActivity - HomeActivity and doing finish (instead clearing tasks), it works as well fine. What's happening?

[android-developers] FragmentActivity and TabHost - I'm not understanding anything
I've seen all the posts of TabHost + FragmentActivity on Google Groups and
on StackOverflow and I'm still getting problems.
And I don't understand anything.
I'm following this tutorial for TabHost and FragmentActivity:
http://thepseudocoder.wordpress.com/2011/10/04/android-tabs-the-fragment-way/
I have the following thing:
in a tab I load a CategoriaFragment.class, where I load a ListView and I
set a ListView.OnItemClickListener for it. When I click, I call this code:
CategoriaFragment fragmentnuevo = new CategoriaFragment();
FragmentTransaction transaction =
getActivity().getSupportFragmentManager().beginTransaction();
Bundle b = new Bundle();
b.putBoolean(flagSottoCategorie, true);
b.putSerializable(sottocategorielista,
(Serializable)sottocategorielista);
fragmentnuevo.setArguments(b);
transaction.addToBackStack(null);
transaction.add(R.id.realtabcontent, fragmentnuevo, FragmentTAG);
// FragmentTAG is the same tag that the current Fragment
transaction.commit();
and yes, I call the same type of Fragment because I need the same recurses
but with another List (sottocategorielista). This is not the error because
I've tried to use another .class and it's the same error.
When I press back button, I get again my first ListView but listeners are
not available. So I click and nothing happens. I've used add and replace as
well.
Moreover, when I try to change Tab, if add is typed, I get several
fragments in the same layout, if remove is typed, I get only one fragment
on onTabChanged, but when I get back to my Fragment, nothing is available.
Moreover if I press back button, I get the `java.IllegalStateException`
saying
Fragment is already added: CategoriaFragment
What should I do?
Everything is easier with TabActivity, which is deprecated now and I would
like to do everything with Fragments.
This is how my onTabChanged works (also available on the resource on the
web)
public void onTabChanged(String tag) {
TabInfo newTab = this.mapTabInfo.get(tag);
if (mLastTab != newTab) {
FragmentTransaction ft =
this.getSupportFragmentManager().beginTransaction();
if (mLastTab != null) {
if (mLastTab.fragment != null) {
ft.detach(mLastTab.fragment);
}
}
if (newTab != null) {
if (newTab.fragment == null) {
newTab.fragment = Fragment.instantiate(this,
newTab.clss.getName(), newTab.args);
ft.add(R.id.realtabcontent, newTab.fragment,
newTab.tag);
} else {
ft.attach(newTab.fragment);
}
}
mLastTab = newTab;
ft.commit();
this.getSupportFragmentManager().executePendingTransactions();
}
}
Thanks in advance.

[android-developers] Loading a Listview from 5MB-JSON in server and start loading a map
Hello, in my app I download a 5MB-JSON which populates a ListView of people. Then, if you click to the map, it shows the position of the people which also shows a infowindow with data. I thought about loading the list, and at the same time loading the map with markers and able to get the infowindow but I've never done this... is this done with FRAGMENTS? Could you give me a link or youtube video to do this from API 8? Thanks! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] USB Host
Hey droiders, Im building an app that communicates with an external sensor, preferably by USB. Now, as many of you already must know, Android smartphones and USB host mode are not natural to one another... But im sure that one solution must be available. At this point i see two possible alternatives: - Grant USB Host capabilities in the android device (dont know how or if is even possible, but im certain it involves hardware configuration somehow) and then port jUSB or JSR-80 or some other java based USB communication solution to android. In this case the switch host/slave must be dynamic in order to assure that the device can still connect to a host itself (computer) - Implement USB OTG (On-The-Go - http://en.wikipedia.org/wiki/USB_On-The-Go) on Android. This seems the most robust option but also kind of difficult... Anyone tried this? By the way, my Android device is HTC magic. Any thoughts or ideas? They are more than welcome.

[android-developers] Action for receiving mail
Hi every one, does any one knows which action could let a broadcastreceiver react on an incoming email? For example, to be able to react on a SMS is needed to add to the manifest.xml the following: receiver android:name=.Receptor_SMS android:enabled=true intent-filter action android:name=android.provider.Telephony.SMS_RECEIVED / /intent-filter /receiver Which action would be equivalent for receiving emails?

[android-developers] Updating applications
Hi to all. How can I update an application that is already installed on an Android phone? I have read something of getting install permissions and then refereeing to the fully qualified class-name for the 'R' class you're refereeing to but I am not clear of how to do this. I am specially interested in being able to add new layouts to an installed app. I hope some one can help me. Thanks in advance.

[android-developers] Single choice dialog item selection
Hi every one. I have implemented a single choice dialog this way:
On my strings.xml I defined the following array and strings:
[syntax=xml]
string name=titulo_pedir_telIngresar número telefónico/string
string name=accion_selecionarAceptar/string
string name=accion_cancelarCancelar/string
!-- Opciones del menu de envio --
string-array name=select_dialog_items
itemEnviar vía SMS/item
itemEnviar vía email/item
/string-array
[/syntax]
and my single choice dialog is defined as it follows in my main.class
[syntax=java]
Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.drawable.alert_dialog_icon);
builder.setTitle(R.string.seleccionar_forma_envio);
builder.setSingleChoiceItems(R.array.select_dialog_items, 0, new
DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int whichButton)
{
/* User clicked on a radio button do some stuff */
}
});
builder.setPositiveButton(R.string.accion_selecionar, new
DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int whichButton)
{
/* User clicked Yes so do some stuff */
}
});
builder.setNegativeButton(R.string.accion_cancelar, new
DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int whichButton)
{
/* User clicked No so do some stuff */
}
});
builder.show();
[/syntax]
The idea of this is that the user of my app selects a item of the
array an base of the selection to realize some action. My problem is
that I don't know how to recognize which item of the array the user
selected. How can I solve my problem? Thanks in advance.

You can try this :
public AlertDialog.Builder setOnItemSelectedListener
(AdapterView.OnItemSelectedListener listener)
Get the item when its selected, and based on the button clicked you
can perform your action.

[android-developers] Receive email sdk 1.1
Hi, on the sdk 1.1 release notes says: The Settings and Email applications are now included in the SDK and available in the emulator. Does any one knows if is possible and/or how to react to an incoming email? With this sdk version I am able to receive notifications of new emails using the mail application on the emulator (having an account configured in this app). As the notification is the same type as an SMS notification and because in the SmsMessage class has methods to handdle email messages I believe this should be possible.

[android-developers] Re: Create graphic interfaces dinamically
Wouter Lagerweij, thank you very much for your answer. I already had consider the second alternative that you mentioned but I think that there must be another way. Your first option was very interesting. I didn't know that was possible to create updates for an android application. Can you tell me how to refer to the fully qualified classname for the 'R' class and which permissions did you used in you application? Finally I got one more doubt. How did you manage to show you update layouts, for example to save information that the user writes on a text field of the app's layout? Thank you in advance. Regards On 23 feb, 16:50, Wouter Lagerweij woute...@gmail.com wrote: The LayoutInflator docs (http://developer.android.com/reference/android/view/LayoutInflater.html) are very explicitly saying this is not possible. You could possibly do something by getting 'install' permissions for your app, and installing additional .apk files containing extra layouts. I've just tried, and instantiating a layout from an already installed .apk seems to work, as long as you refer to the fully qualified classname for the 'R' class you're refering to. Or you could parse the files yourself, of course, and built the UI in your own code. Not very nice, but doable if the layout elements used can be limited.
