Trying it out

● Nemo Mobile images available for N900, N9/N950 and x86

● https://wiki.merproject.org/wiki/Nemo/Installing

Development Tools

● Mer Platform SDK contains the recommended toolset– https://wiki.merproject.org/wiki/Platform_SDK

– Command line based toolset

App development

● Qt, Qt Quick, Meego Qt Componets, and Qt Mobility are good for app developement.

● QtSDK's Harmattan (N9) target– A bit limited, but mostly OK when developing new Qt/QML/Qt Mobility

based apps or porting apps from N9

– Easy to setup and supports also WIN & Mac

– https://wiki.merproject.org/wiki/Nemo/GettingStartedUsingQtSDK

● Developing apps in desktop– Install Nemo's version of Qt Components to your linux desktop and use

normal Qt developement tools

Meego Qt Components in N9 and in Nemo

New App Development

● Develop an app using any of the tools● Make sure it works on x86 and ARM (test on

device)● Create packaging for it in OBS

– Currently MeeGo Community OBS is used for Nemo apps, this is likely to change in near term

● You can release app either via Apps For Meego -repository or if it is good it may be included in Nemo images as preloaded app.

Fixing Bugs in Nemo

● Register and grab a bug from bugs.nemomobile.org● Find sources for the componet, typically from

github.com/nemomobile● Find and fix the issue● Pull request to upstream● Mark the bug fixed● Ask if somebody in #nemomobile could do a new release of the

component or if there is no active maintainer offer to do release yourself
