Worst error ever! Android developers

You will only see a red-x error on your project ... but none of the files are showing they contain an error. So ...


Google led me here 


And I found the following to be my root issue ...

[2010-08-27 15:32:04 – (Project Name)] Error generating final archive: Debug certificate expired on 7/30/10 10:42 PM!



After searching I found this link which suggests the solution: http://www.androidian.de/?p=940.



The problem comes from the fact that Android required the applications to be signed even in the debug mode. So it uses a keystore file called debug.keystore to providde keys for signing applications in debug mode. This key store file has a validity period by default 365 days from its creation date.


This is the site that I followed to fix 

Gah ... where did the time go

- Broken laptop ( Thanks for free repair - Newegg! )
- New shift at work
- Classes at school
- Rift for 6 months
- It was sunny outside

I'm done with excuses, I miss my moonlighting!

Next tier

2 of my wallpaper picker apps have just passed 500+ DL's .... yaaaay!

next up is a video player / selecting app and an customizable email alert app

100 Downloads!

First mile stone with my first app.  I have surpassed 100 downloads and counting!

I am partially torn between making more of the same app (wallpaper galleries) or whether to move onto something new.


I will probably end up doing some type of 50-50 combo with massive grey areas as is my wont.

Download groupings

So by tracking my first app I have been monitoring the range of app downloads, it looks like this:
<50
50-100
100-250
250-500
50-1,000
1,000-5,000
5,000-10,000

10,000 --- 25,000? maybe , at this point i cannot find any examples and my app hasn't gotten to this point yet, so I will update at a later date

• Requests: The number of times your app or site requests to show an ad.

• CTR (click-through rate): The number of times ads on your app or site are clicked on divided by the number of times ads are shown on your app or site. For example, if you show an ad on your app or site 1000 times and receive 11 clicks, your CTR is 1.1%.

• Revenue: The amount of money you earn from your sites/apps

First App !!

Ok, so I made a real simple wallpaper chooser app.  But, that's how we get our feet wet publishing to the market (which was simple, fast and easy)

Goto market and search for 'Akira' , my app should be at top of search!

Step by Step

So, this is where I got started.  I highly recommend get Eclipse first (organizes all your files for you in a package, plus all the tutorials are written assuming you have it).

Installing Eclipse + Android SDK (software development kit)

Next, head on over to the Hello, World ---->.  Hello .... World?

After that, I went through and completed ALL the other tutorials.    Tutorials

Here we go ...

*FIRST POST*

Finished my tutorials, created a simple wallpaper app, moving on to setting up all my accounts to get this thing published.
