followed by errors about "C compiler cannot create executables", "Relocations in generic ELF (EM: 40)", and "crtbegin_dynamic.o: error adding symbols: File in wrong format". This is a sign that you're compiling with your platform's native compiler (due to having CC / CXX set), instead of the android-specific GCC version that ships with the NDK. See {{bug|977817}} for more details; as noted there, the build system may trust your custom CC & CXX variables, when you probably don't want it to.
=== Coding Gotchas Caveats ===
==== Closing resources ====
When handling resources (like Cursors), a try/finally block should be used to ensure these are closed properly. For example:
This is so that in case of ClassCastExceptions you don't get a dangling open resource left behind.
==== Caveats for Timing ====
TLDR: Google recommends using SystemClock.uptimeMillis() for general purpose interval timing of user interface events or performance measurements. If you're adding stuff for timing, use SystemClock.uptimeMillis(), rather than something like new Date().getTime().
