Comment (by sysrqb):

 Suprisingly, #29757 may be needed for supporting API level 16. More recent
 versions of Android do not throw this SecurityException (they simply log
 an error and continue), but Orbot fails during its startup process as a
 result of this exception being thrown, so the app won't bootstrap.

 For example, API level 19 simply logs:
