Android :: How To Declare Pending Intent That Keeps Fresh Extras?
Jun 29, 2010
A few days ago I was struggling to find a way to use custom intents for my alarms. Although I got clear answer that I have to customize the Intents based on some unique ID eg. setAction() still have some problems.This can happen more than once for a contact. And when the second message is generated, the notification is raised well (message is fine there) but the intent when the user actions the notification it uses old data, so previous message is passed and not the brand new message.So someway the intent is caching and reusing previous extras. How can I make it unique per contact and per action?

I've implemented parcelable on a class of mine per the doc instructions, works fine: code...
but I haven't implemented a copy constructor. However, the createFromParcel() method which I did implement is almost like a copy constructor. I'm wondering if I can use it make a copy, but I can't figure out how to get a Parcel instance from the intent extras:
MyParcelable mp2 = MyParcelable.CREATOR.createFromParcel(getIntent().getExtras().getParcelable("key"));// ? just need a parcel ?
it's not the greatest idea, just wondering if it's possible to avoid making another method for my class which will almost be identical to what's already implemented for the Parcelable interface..

I set an PendingIntent on a Notification (notification.setLatestEventInfo). this intent is actually the same intent used to launch my app, only with a flag that I put in the extra (intent.putExtra(TAB_INDEX_PARAM_NAME, UPDATES_TAB_INDEX)).
So my first activity launches, it queries it's intent's extras and immediately navigates to an Alerts activity rather the normal activity on a regular launch.
The problem: from this point, every activation of my app navigates to this Alerts activity. when debugged, I find that the flag is "stuck" in the intent even though I removed/changed it. it just won't change.
How can change an extra on a giving Intent?

I am trying to use Android's LocationManager requestLocationUpdates. Everything is working until I try to extract the actual location object that in my broadcast receiver. Do I need to specifically define the "extras" to my custom intent so that the Android LocationManager before I pass it to requestLocationUpdates so it knows how to add it into the intent, or will it create the extras-bundle regardless when it passes the fired intent to the broadcast receiver?

I put a notification in the status bar with a PendingIntent (with Extras info) that points to my main app (main activity). When the user clicks the staus bar, the PendingIntent is fired and my app launches and I can read the Extras info in my onCreate() method. So far so good.
But if my app is already running, the PendingIntent simply causes the app to come to the foreground and it does not call any of my methods, so I can't read the content in Extras. What can I do?

This questions somehow relates to the question when I was looking to get the extras back in startActivityForResult but now I face another challenge.
I have subscribed to receive ProximityAlerts and I have explicitly constructed the Intent to include some Extras. But when I got the service the extras are not there.
After the answers here is the working code:
CODE:..........................
The documentation says param PendingIntent to be sent for each location update.

I've started using an AlarmManager for some tasks i'm doing and while setting up the pendingIntent to be broadcast I noticed there is no receiverPermission option. Can anyone tell me is it possible to set the receiver permission on a pendingIntent?

That message can occurr if the receiving code crashes or takes too long. I am writing an appwidget for my application, there are like multiple pending intents are there to launch an activity or receive a broadcast. The Problem I am facing is , some times I get exception saying that the Pending Intents cannot be delivered. And the widget does not responds to the touch from the user. please help me. I am not able to find any alternative also.

I have a alarm thing going on in my app and it launches a notification that then when pressed launched an activity.The problem is that when I create more than one alarm then the activity launched from the notification gets the same extras as the first one. I think the problem is either with the intent i put in the pending intent or in the pending intent itself. I think I might need to put a flag on one of these but I dont know which one.The "details" extra is the same to every the next time a notification happens instead of having the different value.Until I set the intents I am sure that the correct value goes to the "details" so its a problem of getting the first intent everytime i press any notification. How can I make it to launch the correct intents?

I would like to create some home screen app widgets that are entry points into an application. I can put a button in the app widget that uses setOnClickPendingIntent to start the activity. The problem occurs when I want to have two of these app widgets that are entry points to different parts of the activity. I need to be able to pass data into the activity that will distinguish these. Since both app widgets use a Pending Intent that starts the same activity, the two Pending Intents are shared and I can't reliably set extras for the corresponding intents.

I created a widget that when clicked activates a PendingIntent.The problem is when I have more than one widget on the screen only the latest one will start the PendingIntent.I have read some about a unique request code, but not figured this out.Any ideas how I can have multiple widgets and the PendingIntents work for each?

I have one WidgetProvider but expect the user to have multiple instances of the widget on the home screen. When the user clicks on the widget, an intent is fired to start an activity A passing a String extra (which is specific to that instance of the app widget). Everything works fine unless the activity is already running, in which case the activity is shown in its previous state (and so the intent extra data is ignored). I've tried using various Intent flags (like FLAG_ACTIVITY_NEW_TASK) but they don't seem to help.

I've read many posts on the same topic and tried all the given solutions without getting the result I want.The program should start an intent with extras from a notification.The problem is that when a new notification is shown, the extras added to the intent is the same as in the first notification. I've triend with differnt flags in both the intent and the pending intent, without result. What am I getting wrong?If i just launch the same activity (and the same extras) with a button, everything works as it's supposed to.

In my application i have created pending intent which calls another activity (after 20mins of alarm off) with the help of alarm manger. It should happen each time for each new pending intent or when I call that activity. But when i create one pending intent and after few mins again create new pending intent ,then the last one overlap the other previous pending intents and start specified activity only for ones for the last pending intent.I want that each time i create any pending intent it should start specified activity after 20 mins of it's alarm off time.How it can be done ?

I have a preferences.xml that looks like this:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference android:name="Sample" android:enabled="true"
android:persistent="true" android:summary="Sample" android:defaultValue="3.0"
android:title="Sample" android:key="sample" /> </PreferenceScreen>
When I do sp.getString("sample", "3.0"), it works fine and returns a string, but it shouldn't be a string, it should be a float. Running sp.getFloat("sample", 3.0f) throws a ClassCastException because it is a string. What should I put in the XML so that the preference is stored as a float?

Please let me know that where we plan which permission has to get by other application to get data from a application.

I have a little doubt, I spend data from Activity A to B with a bundle in the intent.Where I should declare the keys? In Activity A or B? Only to avoid confusion, I'm talking about the string that defines the data that will be set in the Bundle.Ex: public static final String KEY = "MyKey";
I declare always in the Activity A, but I think that if I could let all the keys in a file would be better, like keys.java or something like that.Obviously, this is nothing that is generating errors, just a doubt about convention, a thing that I consider very important in software development.

I am currently on tmobile using a vibrant. The bugs with the vibrant are starting to bug me, and there is no where else to go to for tmobile. I am thinking about going to sprint for the EVO. I will have to figure out a way to get out of my tmobile contract, (hasn't been 14 days) if anyone wants to help me with ideas.
my main question is, is it true that you have to pay an extra $10 a month for the Evo? I don't have 4G in my area, do I still have to pay for it? What kind of deals can I get from sprint for a new contract? Can I keep my same number?
