Basically, i have purchased HTC Hero (Android sdk 1.5) , but i just got the notification of “System software update” and i agreed to update the sdk to 2.1-update1 .
I was developing application for android sdk 1.5 successfully, but now i have created a Hello world application for the Android sdk 2.1 and then when i am trying to run it on my updated phone, at that time below screen is showing up:
where you can see ?????? in serial number and Taget is shown as “unknown”.
On console window, it is showing up an error: “Automatic Target Mode: Unable to detect device compatibility.”
(1st question): What i need to do to run the application(sdk 2.1) which i am developing ? pls let me know
And ya, when i am trying to connect phone using USB cable, it is showing an alert dialog regarding “Choose a connection type:” showing below options:
- Charge only
- HTC Sync
- Disk drive
- Internet Sharing
(2dn question): so which mode should i select for the development of application and running it on phone.
Maybe your udev rules have to be modified. Read this guide to fix them. I don’t know why a SDK upgrade should have modified this, but I think this might be your problem.
