 The KOReader Android build requires `ant`, `openjdk-8-jdk` and `p7zip-full`. A compatible version of the Android NDK and SDK will be downloaded automatically by `./kodev build android` if no NDK or SDK is provided in environment variables. For that purpose you can use `NDK=/ndk/location SDK=/sdk/location ./kodev build android`.
