Previously any library created using gobind used reflection to get the ApplicationContext. The methods used are disallowed in Android 9 causing any library to crash. However the ApplictionContext is not required and only needed when using RunOnJvm. This change adds an method to set the ApplicationContext when needed, but will not get it by default by using reflection.
