问题
I have Market version 2.3.6 and I was trying to test the sample application per the instructions which state that:
If your device is running Android 3.0, in-app billing requires version 5.0.12 (or higher) of the MyApps application. If your device is running any other version of Android, in-app billing requires version 2.3.4 (or higher) of the Android Market application.
Well, my device is running Android version 2.3.4 and Market version 2.3.6 and the sample application kept greeting me with an error message, saying that I "cannot use the Android Market at this time".
So, I manually started the Android Market, then went to check the version (in the Settings > Manage Applications) and I was reading the information, it automatically changed from 2.3.6 to the latest 3.4.4.
Now the sample application runs without this error.
So my question is why did I get this error message?
- Is it due to a "bug" in the documentation and really In-app Billing requires the LATEST Market version and not not v2.3.4 as documented?
- Or is it because my attempt to run the sample application caught the Market application in transition, i.e. during an automatic update?
