Gmail Text Cloud Widget

ive been enamored by some of the more simple text based widgets as of late (like simplistic text and clockr) and decided to try to make a widget based on that design for gmail. it will display who the email is from in a text cloud where the most recent email is the largest with each subsequent email getting smaller. if the email is unread it will be bold, if not then it will be regular text.
my background is in making java apps for the command line and of a more linear layout. so i am learning android dev as i go. because i am learning as i go i am starting at the most basic and moving on. i have a widget with a text box that displays '0'. (yay! i know impressive). now i want to make the text increment by 1 every 1 second. (yes not very useful, but very useful for learning.) i want to do this with an AlarmManager. does the AlarmManager have to be in a service, or an adjacent activity, or could there be a static AlarmManager in my AppWidgetProvider class? i found some examples but they are all pretty complex. i want to start super simple and move towards advanced.
after that then i will do the same increment except each number will be added as a new textbox and the previous will decrease in size. and so on and so on.
any help would be greatly appreciated.

so i understand that a Handler is better for these small tics of times but doing this project is a learning excersise. let me show you what i have so far.

}
}
what ends up happening is that my widget just shows [0] in white and 60sp big. never changes. and my toasts in the service never show up on the screen. am i starting the service wrong?

Is this just a stupid question or does no one know the answer? Cause if no one knows then nvm, wrong place to ask...
Its from my damn phone!!!

I haven't messed too much with app widgets, but don't you have to set some sort of refresh time in your metadata?

yep, that determines how often the ACTION_APPWIDGET_UPDATE intent gets sent.
my gitc_widget.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:minWidth="146dip"
android:minHeight="72dip"
android:updatePeriodMillis="1000"
android:initialLayout="@layout/main">
</appwidget-provider>
buuut. after android 1.6 or maybe 1.5 that android:updatePeriodMillis tag defaults to 30minutes. which is why an AlarmManager must be used for anything less than 30min updates. and since i dont want to wait 30mins to know if my code works i need my service to start.
i have determined that my service never starts. it isnt shown in the running services on my android phone and the toasts from it never show. anyone know why the service isnt started?

As mentioned earlier, I don't know a lot about appwidgets, but they are incredibly difficult to debug and I've had to reboot the phone at times to get past bugs in my code, so don't be so sure that your service isn't running. First, I don't think AppServices show up in the "running services" tab, and second, I don't think toasts from a non-activity show up on the screen. I could be wrong about this, so don't take it as gospel. Try using Log() instead of Toast for debugging.
Also, I don't see anything in your code that sends an update to the appwidget. I think something in your service should eventually call GITextCloud.updateAppWidget().

Thanks for working with me. In my AlarmService class in the onStarted method i call the setRepeating() method that gets passed a class with wich it makes an intent that the AlarmManager should use to trigger the onRecieve() method in my GITextCloud class. I will look into the log(), thats a good idea. And i will be trying to setAction() on that intent and then specifically catch it in the onRecieve() method
Thanks for giving me something to think about
Its from my damn phone!!!

i made some edits and ran into a problem where my intent was caught be onReive() but the local variable called count never incremented... this is crazy! a block of code that would execute whenever a particular intent was recieved never did what i wanted:
count++;
refreshWidgets();
Toast.makeText(.... some indication this was done ...);
the toast was always displayed but the count never incremented. i thought the refreshWidgets method was bunk so i manually set the count in the method... everything was good... then i make a toast after the count++ to display count. count never incremented. well after messing around i found that i had count as a
private int count
i changed it to a
private static int count
and it worked! weird...
this is my final code that makes a number on a widget increment every couple of seconds. note: setting a repeating alarm with the AlarmManager for a small amount of time did not work. i had to make a nested one time alarm that kept rearming itself. and i got rid of the service cause some of the debuging tools in cm7 said it never started. cross that bridge when i get there....

Android/Java Newbie

Hi all, im having a go at developing a simple app. i have little experience with Java and Android development. i have a little test app at the moment and have created a new class, im trying to create a new instance of this class on a button click. it fails to do so, i cant for the life of me see why so.. can someone shed any light on this?
Thanks

I don't see anywhere in your code where you are calling the mainButton(View view) method. In the Android lifecycle, the onCreate method is the equivalent of a normal Java program's main() method, which means that code execution begins with the first line of onCreate(). Not knowing what you're trying to do, a good start would be to call your mainButton() method AFTER setContentView() in onCreate().
Side note: your mainButton() method has a View parameter that is never used. Is there a reason for that?
Android activity lifecycle: http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle

You have to use an intent on that button click, use the method onClickListener and define the intent in the androidmanifest.xml
e.g
Code:
Button button = (Button) findViewById(R.id.[B]button[/B]) // replace latter button with actual id defined in main xml.
button.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View arg0) {
// TODO Auto-generated method stub
startActivity(new Intent("[B]com.example.packagename.CLASSNAME[/B]")); // this should be your own package name.
}
});
Also define this in android manifest under the <application> and </application>
Code:
<activity
android:name=".[B]CLASSNAME[/B]"
android:label="@string/app_name"
>
<intent-filter>
<action android:name="[B]com.example.packagename.CLASSNAME[/B]" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Change the values of BOLD text according to your own values.

Nope! He didn't say that he wanted to launch a new Activity when the button is clicked. He wants to create a new instance of his LocationFactory Class.

Oops yeah right read that now...I thought he want to start an activity... Anyways tried to delete my reply but not getting an option to delete.

There are many flaws in his code. And the other thing is if its his first app and if he has low level of programming experience then according to me it would be a next to impossible app for him, as per his code and what he is trying to implement.
I think he should rather start up with small apps, understand things and then move on to complex apps.
P.S - its just my opinion

Agreed that he should start small...which is exactly why your suggestion for creating and handling Intents makes no sense. Before that, he should first understand the activity lifecycle. Until then, he can just stick to trivial single-activity apps to gain experience.
OP: This code should be placed in the onCreate method:
Code:
Button button = (Button) findViewById(R.id.your_button_ID_here)
button.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View arg0) {
mainButton(); // get rid of the View parameter in this method...it's not needed
}
});
This will cause a new instance of your LocationFactory to be created, and will also cause your Toast message to be displayed.

thanks for the replies. yes you are right in that i am inexperienced, but this is just a test app for me to play around with and learn on. i tend to learn better by doing rather than constantly reading. thanks for your suggestions ill look into them

I also believe in the same, I also keep on doing experiments and testing things out.
What I would suggest is that start with a small app and understand the insights on how android works and all...

Potential Solution
Alright, I think I've found your problem. Have a look at where you define your variables in your LocationManager class:
Code:
private static final Context Context = null;
Geocoder geocoder = new Geocoder(Context, Locale.getDefault());
LocationManager manager = (LocationManager) Context.getSystemService(android.content.Context.LOCATION_SERVICE);
This is your problem:
Code:
Context Context = null;
If your context is null, and you use it to create a geocoder and call Context.getSystemService, you'll hit a null pointer. You're trying to access an object (the Context) that doesn't even exist
I'd recommend you pass the context in the LocationManager constructor and then instantiate your objects there. That's standard java procedure.
Code:
private Context mContext = null;
Geocoder geocoder = null;
LocationManager manager = null;
public double Latitude = 0.0;
public double Longitude = 0.0;
public LocationFactory(Context context)
{
this.mContext = context;
this.geocoder = new Geocoder(context, Locale.getDefault());
this.manager = (LocationManager) Context.getSystemService(android.content.Context.LOCATION_SERVICE);
}
I also renamed Context to mContext - it's generally a good idea to keep the instance's name separate from the class name.
Try that - it should work. Please feel free to ask any more questions - this is how I learned, and I think it's the best way!

Read This guide first, then it's easier to help you.
What I'm seeing is that you should set your message=getIntent ().... ; in the onCreate since the Intent data is probably not available before.

The implementation purely depends on you. You can inflate multiple list views.
