I can't say for all of those errors, but some of them you definitely must fix (like *incompatible types: String cannot be converted to char* or * java.util.concurrent.CountDownLatch*; -- it's might be not supported by codename one) . Your code could be ran smoothly in the simulator, but for Android build there is all another process and some things might be not supported (for example *CountDownLatch -- *Shai will know better if it's supported or not). So you need to find a way what to change it to.
