The APK template declared EVTestActivity (the zeroerr test host) as the
MAIN/LAUNCHER activity, so a game packaged with ve build android opened the
test host (which unpacks assets/test, absent from a game APK) instead of the
game. Point the launcher at EVEngineActivity (unpacks assets/game and runs
ve run <game>); the test suite already starts EVTestActivity explicitly via
am start. test-sdk.sh now fails the android SDK smoke if the launcher regresses.
