I'm trying to capture when a calendar reminder goes off. What I'm trying to do right now is use a BroadcastReceiver and receive an intent from the calendar. Is there an intent that gets broadcast when a calendar reminder goes off? If so what is its name, or where can I find it? Is there a list of all the calendar intents somewhere?

I have an IntentService that broadcasts an Intent each time if finishes some work. Each broadcast Intent is identical except that it contains a Bundle with some result information from the IntentService. Evidently, having different data in the Bundle is not enough for Android to think it's a different Intent. If the IntentService broadcasts two of these Intents back-to-back, the second one is dropped as a duplicate.
I know I've read about this behavior in this forum in the past but I can't find in the documentation where this duplicate elimination logic is described in detail. Mostly, I just want to differentiate the Intents enough that they are not considered duplicates. Any pointers would be appreciated.
I need to be able to handle/catch Intents while my Activity is closed. So I am looking at either a Service or a BroadcastReceiver. Is it possible to "receive" intents to a service itself? I tried to search, but could not find anything helpful. With a BroadcastReceiver, I am not exactly sure how that works outside of an Activity. Does it depend on the Activity being open/running? Can it run by itself?
Let's say that my Activity is killed by Android(or a task killer app), does the BroadcastReceiver still receive intents and process them? I have used a BroadcastReceiver as a widget, but I do not want to use a widget this time. My goal is to have the user open the Activity to set some options. From there, they would be able to close the Activity, but I would still be able to process Intents that were sent out by the system. I am still fairly new to Android development, so I could be so far away from where I need to be.
I was just working on an application that will do stuff when a call is missed or made; and am left wondering why do you have to register a listener using a long lived background service for phone state changes instead of being able to use broadcast intents?

View 8 Replies View RelatedI am attempting to listen for system fired Intents, specifically regarding text input, using a class extending BroadcastReceiver. I see there is an Intent called ACTION_INPUT_METHOD_CHANGED (android.intent.action.INPUT_METHOD_CHANGED) which I hope to be able to use to know when the keyboard or text input is attempted by the user. (I assume this intent will work as I can use an InputMethodManager object to handle keyboard related tasks)
My java code:
package com.BroadcastReception;
import android.content.BroadcastReceiver; import android.content.Context;
import android.content.Intent; import android.util.Log;
public class InputMethodChangedReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
if (arg1.getAction().equals("android.intent.action.INPUT_METHOD_CHANGED")) {
Log.d(this.toString(), "Event Fired");} } }
I was wondering is it possible to register a broadcast receiver to receive two intents? My code is as follows:
sipRegistrationListener = new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(SIPEngine.SIP_REGISTERED_INTENT.equals(action)){
Log.d("SETTINGS ", "Got REGISTERED action");
} if(SIPEngine.SIP_UNREGISTERED_INTENT.equals(action)){
Log.d("SETTINGS ", "Got UNREGISTERED action");
} } };
context.registerReceiver(sipRegistrationListener, new IntentFilter(SIPEngine.SIP_REGISTERED_INTENT));
context.registerReceiver(sipRegistrationListener, new IntentFilter(SIPEngine.SIP_UNREGISTERED_INTENT));
I get the registered Intent everytime I send it but I never get the unregistered Intent when I send it. Should I set up another Broadcast receiver for the unregistered Intent?
I want to received the Android broadcast, is there a list of all intents?

View 2 Replies View RelatedI'm an experienced C++/Java dev who has been truly enjoying that past two days of getting neck deep into the Android SDK. I can foresee a lot of sleepless nights ahead Now, being arrogant due to experience (lol) I basically wrote a hello world Activity, got it to work and promptly decided to write an out of process service with accompanying client for project #2. Android is so well thought out (if not exactly documented although that's an 'over time' issue inmho) that I had basically implented everything but callbacks into the client before realizing (and feeling like a total idiot) that there's a very nice example called RemoteService (lol @ me - again) Basically, this validated everything I'd been doing, although I did notice that because my client is in its own project and namespace and my service is in another project and namespace (but the same Eclipse workspace) that I had to have the service entry in my service's manifest AND my client's manifest (that one took me a while to figure out) in order to bind on the service. Anyhow, everything's great, I am starting to love on Android (figuratively) but I've run into <BRITISH-NESS>a bit of a sticky wicket, eh, wot?</BRITISH-NESS>.
When my client Activity binds on my service (which is running in its own process) and calls the equivalent of 'registerCallback', the interface is added perfectly to the RemoteCallbackList object and I can immediately (right on the next line of code) use the interface to send a notification to the client. Now, my problem is that when my main service thread tries to pull the interface out of the RemoteCallbackList via the broadcast methods, the RemoteCallbackList is always 'empty' - it returns 0 from beginBroadcast. After double checking ensure that I AM actually adding it to the list (because I've been a collossal idiot before) and that I am getting success back from 'register', I immediately think it's a threading issue, so: I add logging code to the service in key places to log what the thread id is repeatedly, and I think "uh, I think I need to use a handler of some sort to make the call back in the thread that handled the registration" and to double check I call beginBroadcast right after 'register' and find that it always returns back the correct number of callback interfaces. So it VERY much appears to be a threading issue (to me) so now I'm a bit stuck I've written a handler so that my main service thread can request the correct thread to actually call 'beginBroadcast' and then thought 'how is it going to know what thread that is...?' and instead am now thinking I need to pass, via a handler or something, the incoming interface from the thread that runs when the client calls the equivalent of 'registerCallback' to my main service thread. What part of the proper paradigm am I missing? BTW, as an example of the thread IDs, my main service thread is #1, the runnable I use for tasks in the main service thread shows an ID of #1, the message handler I was thinking I could use, shows an ID of #1, but the thread ID I get in my code in the service that runs when the user registers their callback is #7.
If I plan to notify clients when the service notices something it thinks they need to know, do I need to notify (somehow) the clients via the thread with ID #7 or do I need to pass the interface I get when the user registers their callback from thread #7 to thread #1 and call 'register' on the RemoteCallbackList from thread #1? Sorry for the verbosity but I figured more is better than less. Again, everything works great except this one little part.

View 3 Replies View RelatedI'm trying to figure out if a system event broadcast is broadcasted using ordered broadcast or normal.The event is EVENT_REMINDER and in the source for the calendarprovider i noticed it sets up a alarmmanager to sent the broadcast. I can't find how the alarmmanager sends it. My guess would be as a normal broadcast , But while i was trying some things i noticed i could delay the system's notification (tried up to 10 sec) by building a sleep in my broadcastreceiver. This would indicate that they are handled ordered , and the systems receiver is only called when mine has finished. But can i be sure of this behavour?? (in all 1.5> sdk versions) the docs state that in some cases normal broadcasts are also handled ordered..due to spare of resources.
View 1 Replies View RelatedI'm desperately looking for an app that will integrate a calendar with lists, to do lists and I am willing to pay for it.
Here's what I'd like:
a calendar with daily, weekly, monthly view
To do lists (which can be synched with the calendar and crossed off the list if completed on a scheduled day)
Reminders, alarms, deadlines
Ability to work offline (in case I'm in an area w/o service)
Ability to setup recurring appts
Lists (e.g. grocery, books to read, people who owe me $, etc.) - where I can see ALL the lists in a nice lay out and be able to prioritize within lists
All of the above should have a widget so I can see my calendar/lists from my homescreen
Ability to add comments to any of the above
Does anyone know an app that does all these things? I've tried: TooDo, Astrid, Jorte, etc. Jorte seems to come the closest so far...
trying to create a broadcast receiver which responds to system events and change system settings. I don't need any interaction from the user so I don't need an activity and have been trying to do everything through the manifest file. I've put a log event into my onReceive method but it never logs anything so I'm presuming my method is never called. I've tried this with both the 1.5 and 1.6 SDKs. I was hoping somebody could have a look at my code please and let me know if there are any problems.
View 2 Replies View RelatedI have been considering a new phone since my 3rd iPhone suffered it's demise and is no longer under warranty (1st Apple update bricked, 2nd stopped functioning, 3rd touch screen has gone wonky). So I have a choice to buy a new iPhone (or refurb) or go Android.
So far I have been impressed by the Android that my co-workers have. Seems very response, seems very snappy, seems pretty polished. I do have a couple questions: Is there a way to get a home screen of the droid to list out the next coming calendar items? I miss this feature from the BB and WiMo sets. Same with emails.
Does anybody know how to save the calender list view on one of the home screens.
View 1 Replies View RelatedI use google calendar, I organise a little football team, where it is common for games to be changed for various reasons. I made a Calender with the fixture list and used the public URL to share it with the team, most of whom then imported it to the calendars on their smart phones. I then tested to see if I changed information on my calendar if their calendars would update. I found that the IPhone users calendars did but not the android users.

View 3 Replies View RelatedI am developing an application which is communicating with the server. Tha application can perform log-in and get different parameters from server.
The application consists of a RESTful client (custom class for making requests), Communication Service (the service which runs in the background) and the main activity.
For now I created multiple broadcast messages and multiple broadcast receivers in the main activity so when the application performs login operation a receiver (loginBroadcastReceiver) in the main activity receives a message and when another parameter is received from the server different message is broadcasted and another receiver handles the message.
This way however the application performance is poor but I am not sure whether it is due to multiple broadcast receivers.
Does anyone know what is the best way to exchange data between service and main activity - is it better to create a single broadcast receiver and retrieve all parameters from message or is it better to initialize multiple broadcast receivers for multiple parameters?

I have a auto-complete textbox in which the user makes a selection. From here I want to load a tabbed layout which is based on the user selection. The problem is I cant figure out a clean way to pass that selection to each of the tabs. At the moment I can pass an intent to the 'tabhost' activity and then pass to each child activity explicitly, however this just seems like messy iterative code to me! So basically how can I pass my intent data bundles to the tabs activities cleanly & efficiently! Psuedo code is also very welcome.
View 2 Replies View RelatedI am trying to create intents that will be set using alarmmanager. Currently, I can do this with one intent, add extra data to it (strings, but i send them as one string with a seperator), and everything works fine and goes off at the correct time. However, when I try to send multiple intents like this, they are overwritten and only one goes off at the correct time. How can i structure my intents so that they appear different to the alarmmanager (i think they are getting deleted when filterIntent() is run).
long story short- putExtra() makes all the intents look the same still... how can i make them look different so they wont get deleted (and keep track of them in case i want to delete a specific one)
I have searched and searched and I just can't get this code to work. I have a main.xml layout and a setting.xml. I have some values I would like the Settings.class to change in my main apps class.Three string to be exact. I have tried this simple test code in my main app class.
settings.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), Settings.class);
startActivityForResult(intent, 0);}});
//Then a function
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent){
super.onActivityResult(requestCode, resultCode, intent);
Bundle extras = intent.getExtras();
String value = extras.getString("myKey");
if(value!=null){
Log.d("hmmm",value);}}}
In my settings.class I have the following
returnHome.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.putExtra("myKey", "YEAH");
setResult(RESULT_OK, intent);
finish();}});
Back in main app class it is not getting logged. Like I said I have three string in the main class that I want settings class to change and send back.
On the market, there's an application called App Protector, which seems to effectively block the launching of configured activities until a password is correctly provided. By default, it blocks access to itself (not very interesting), Settings, and a few others. I wrote my own app to launch settings (rather than doing so through the home screen) and App Protector continued to do the job it claims to do.
When an activity that is protected is started, App Protector's password input activity is shown instead. Once the correct password is provided, the activity that was started comes to the front.
First -- does anyone know how this app is able to get between the rest of the system and the activities it protects? I would like to do something along these lines in my own application as well. Perhaps this app is receiving a broadcast about other activities coming to the foreground, and when the foreground activity is protected, it forces itself to the foreground?
Second -- does anyone know how well this technique will stand up to attack? Are there other ways to circumvent, where start Activity(...) fails to? It seems that one could use adb to un install it, thus removing its protection easily, but if I pursue my plans here, the app will be a part of a device's firmware (which, I assume, offers some protection against its apps being installed?)
Found similar examples--not exactly what I need. I simply need to start messaging (SMS) and email intents from my app with their "to" fields already populated. So I need to send a number with the sms intent and an email address with the email intent.
