The idea behind the droidcon conferences is to support the Android platform and create a global network for developers and companies. Droidcons offer high-class talks from different parts of the ecosystem, including core development, embedded solutions, augmented reality, business solutions and games. Droidcon covers all aspects of the Android ecosystem from mobile devices, to TV, to cars, to gaming, and so much more. It is organised by local partners with support of sponsors from big blue chips of this industry to SMEs and a lot of volunteers work.
