Step 2: Download Sipdroid on the Phone



 		 -> Open the email in your phone or type in the address manurally.  If the customer can't access the email via his phone they will need to put in the URL manually. I suggest using a URL shortener like Tinyurl.com

-> When the customer clicks the link it will begin to download
the  package to the phone. Once the download is complete
simply click the package to beign instillation
Step 3: Click INSTALL on the installion screen

 -> Step 4: OPEN when it's done

 -> This will Launch SIPDROID

Troubleshooting AirDroid

Installation Failure

When setting up the Airdoid as a device one of the fields asks for the telephone number of the mobile phone. It can be entered with or without the leading 1, so 15555218135 or 5555218135 will both work. When the Airdroid App is created it has a check that runs and verifies that the phone it is on matches the phone number. If someone has downloaded the app on another phone they will get an error:
 

 This is the error caused when the number provided earlier doesn't match what is on the phone. This is to keep the Airdroid limited to one phone, so if the customer  was planning on sharing it, they can't. This can cause a problem though, it relies the telephone to know what number it is using. You can see what number by having the
customer go to the SETTINGS in Android menu, then ABOUT PHONE, then STATUS.


             
        
  
The status page gives some information, the important bit here is "My phone number". It should be listed as 15555218135 (G1) or 5555218135 (all other Android phones). This is the number the app checks against, although you don't have to worry about the leading 1, the number itself is important. This can also lead to a problem, there is a know issue with some android phones (right now it's just been on T-Mobile but it could be any of them) where this "My phone number" field is blank. When this happens Airdoid won't install because the check fails. The error will say;
Where it will normally show the number of the phone, it will be blank in the error message. Unfortunately this is a problem with the telephone and can only be fixed by the cell provider. In the reported cases they just had to call their carrier up, explain that this was missing and they could fix it remotely with an Over The Air (OTA) update.

            This can also cause problems if A) the customer changes the number on the phone, or B) they swap SIM cards, which is a popular thing for people who travel internationally. Either of these will change the number of the phone and Airdroid will fail. It is important to note Airdroid checks this every time it runs, not just once.

Registration Error
When the phone is registered properly there will be a
GREEN. When the Airdroid is attempting to register
the indicator will appear as YELLOW


 -> If the register fails the indicator will turn RED




 -> If they get a red status they can pull down the top menu for more
information If this happens trobleshoot as you would any other
error. The most common  causes are  a registration conflict
 or 401 problems caused by a router.
