Number Saver (Android application)

A very basic feature that I was missing in my Android phone is the ability to save a number while I’m in a call. Sure you can go to the home screen, and open up any app with a textbox, but I decided to create a dedicated application.
So, meet Number Saver!
UPDATE: Number Saver got a new look
Basic usage guide:

When you open the app you will get the main screen:
From here you are able to enter the number, copy to the clipboard, and clear the clipboard if it is full. Also, when you open the app, if there is a text in the clipboard it will already be in the text box. So you can press Dial to instantly dial the number
Also, during an active call you will notice the note and pencil icon. Stretching the notification area will give you the option to launch the application.
This app is available for free through the Android market. Donation is always welcome …

First steps in Android programming

Last week I finished my first Android application. All through the development stage I had to Google a lot for examples which some were really hard to find (even though you can find reference for everything in the SDK, for me, it’s easier to understand from a code sample).
My mobile company allows you to send 10 free daily SMS through their website, and after that each text message is still half priced, so I decided to take a challenge and create a UI that allows me to send my messages from the phone through the website automatically.
The core of my software was pure java, so even though it wasn’t straight forward to accomplish, I kinda know the material.
The main issues were after – when I got to the android implementation and UI
Here are the issues I needed, and will supply examples for in this post:
(Of course – for you that are more experienced than me with Android development, please forgive if I’m not doing everything ‘by the book’, it’s simply what I could find. So if you have any suggestions or improvement please send them to me or post a comment J )

  • How to find out if there is an active network on the device
  • How to create options menu
  • How to create and clear notification in the notification area
  • How to declare your program as “SMS Sender” (‘Complete action using…’)
  • Taking care of orientation (Landscape and Portrait mode for UI)

Here is the code I ended up using. Hope you find it helpful

VoIP for Android is in town


Well, At least when it comes to SIP communication
Update:
Well, there has been a great leap in Android support with VoIP. Skype has released a decent client for most Android based phones (with the exception of Galaxy S, and USA Based clients cannot use 3G), and I have discovered another excellent VoIP client for Android called cSipSimple (If you liked Sipdroid I advise you to check this one out as well. It’s my current default).
Other than that, the upcoming Android 2.3 is said to have native SIP support which is extremely cool
Having said all that, enjoy my original post 🙂

A Smartphone, as its name implies is… eventually… a smart phone! Exactly! That’s what I thought. And as one I should have the ability to run any software that is compatible with its hardware and software.
That turns out to be almost true. VoIP is off the limit.
And it is not because the device cannot handle it, Far from it. It is because mobile companies are afraid for their revenues. When people are using VoIP on their infrastructure, it takes away money from them. Oh you poor phone companies. My heart goes out for you.
And after all the tears run out, I went out to look for some VoIP that DOES work for me. SKYPE of course was off limit. Even though there is “Skype Lite Beta” for Android, it does not support Skype-to-Skype user call. And why should it? Skype is an excellent IM software and VoIP is only secondary (wink).
I then stumbled upon SipDroid. Sip droid is a SIP client for android. This is great if you have a SIP account provider. I for instance, have an account which runs on asterisk server (open source IPBX system).
I got the installation of SipDroid at once! And installed on my phone to try it.
What can I say? It has huge potential. But it is only fully compatible with its mother ship, which is pbxes.com. Luckily (but of course – not a solution) they allow you to enter your own sip account there so you can connect to it through them (like connecting to your neighbor through china… but it works). Although pbxes.com has a strange certification error they claim is negligible.
So, using it directly with asterisk server causes poor outgoing audio which is lame. I’m sure some people might be able to tweak their server to handle it directly and properly but I didn’t manage to do that… nor found proper idea sharing on that subject.
But this client is still in beta stage so I honestly believe it will kick ass when it’s complete.
It’s no Skype, and I hope some Skype-like client like Fring will port soon for Android, but until then, it’s better than nothing.
Two important notes if you want to use it:

  1. If you are planning to download it from the Android Market – You will get a limited version which disables usage of VoIP over 3G/EDGE. So if you want the full one then download it directly from the project page.
  2. VoIP data, is currently 1.20mb per minute, so watch your data plan
