Orbot start up problem/looping dialog

#1. Almost always it takes two (sometimes three) starts for Orbot to connect properly. One symptom is in #2 (closed) below. Another is that all looks good (connection sequence looks correct, drop down alert looks correct) but testing via check.torproject.org shows no connection. Exiting and restarting usually yields a working connection. #2 (closed). Frequently on the first try, the app shows the spinning white circular pattern in the black rectangle in front of the Orbot logo, "Orbot is starting" message under the logo, and then stays in that mode indefinitely.
