Hello Moser,

Please make sure you QCAR_SDK_ROOT is checked in the "Order and Export" tab of your project "Java Build Path". This can be found by right clicking on your project and selecting "Properties". From the properties window select "Java Build Path" on the left. In the "Java Build Path" window select the "Order and Export" tab and make sure QCAR_SDK_ROOT is checked.

Thank you,

-Peter
