when using this method

android.content.pm.PackageManager.currentToCanonicalPackageNames(String[])

according to the dev doc

The problem happens on device Moto Milestone, with 2.1-update1 Android version.

Is this because of the modified ROM by Moto?

Any advice is appreciated.

The method you are trying to use was introduced in 2.2 (version 8), so with a 2.1 device you're not likely to find it.

Check the build version before trying to use the class that calls that method or do a funky workaround using reflection?

  • Yep, this is the problem. To wit, if you need an API 8 method, require API 8. If you don't want to require API 8, don't use API 8+ methods. – kabuko Oct 29 '11 at 08:26
