hi
I tried to upgrade it on G1. I got it failed as below.
Note : i installed TEST_V1.apk on Device. Now I want to give another
version but I want to give another app, which needs to use the data
which is already in version 1. So, I made 2nd version as TEST_V2.apk
and tried to install. but it failed as below. Can anyone help me on
this ?
D:\android-sdk-windows\tools>adb install TEST_V2.apk
943 KB/s (271755 bytes in 0.281s)
pkg: /data/local/tmp/TEST_V2.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]
Thanks,
