I finally finished my first Android application to the point that I wanted to try to start using it on my phone.
This post explains how to install applications, but I had some problems:
First, with installing from the SD Card, it doesn’t say exactly what application to use. From the Market, I installed “AppsInstaller” developed by ModMyMobile.com. When I opened the program, it scanned my card, and found my application that I had uploaded via the USB cable. But, it said that the applications were blocked and offered to take me to settings. I check the “Unknown sources” option which is described as “Allow install of non-Market applications”. Then, it worked!
Also, I tried to install with adb, but I couldn’t get that to work. When I ran “./adb devices”, I don’t see any devices listed. This “G1 usb drivers for linux” post looks promising, but I haven’t finished going through all of the steps. I will try to post back when I do.
