DEVELOPMENT

Failed to load JVM.dll (Nokia SDK v1)

NOKIA SDK 1.0, Failed to load share library for jvm.dll.

Use JDK 32 bit (not 64) coz this Nokia SDK is based on Eclipse 32 bit (not 64). If you’re using 64 bit please bare in mind. The best is download JDK 1.6.038 (32 bit).

Nokia IDE – issues, cannot load the device.

- GO to Windows-> Preferences –> Device Management, and click Manually Install. Point to the Nokia SDK.

Sadly, maximum you can upload only 2MB of the installation package of your apps to Ovi Store, s40 does not have local database, and you need to consider the low speed connection since most of the Asha line only support 2.5G Internet connection…
