Download the AndFlmsg apk file from the website at: http://www.w1hkj.com/vk2eta/ And save it to the SD card, either from within the phone or on a PC to which the Android device is connected to and has the USB driver installed for that device to allow access to the SD card content from the PC. From there use a file explorer to install the .apk file, or on some devices use the notification of the completed download to install. You have to allow non-Android market application to be installed for this to work. This is found under Settings / Security / Unknown Sources OR Setting / Applications / Unknown Sources, for older versions of Android. You will be asked to accept a series of permissions that are explained below: a. Your location: to provide GPS location for Picture forms or provide accurate time when out of cellular range (available but not displayed yet). b. Storage: Read and write to the SD card. For storing and accessing the working files under the "NBEMS.files" directory. c. Your Personnal Information (log data): to allow reporting of the context of an error in case of an application crash (the user can decide to send or not the information after reviewing it). d. Network Communication as in Bluetooth and Full Internet access: to allow connection to the Bluetooth handsfree kits or headsets used as audio interfaces AND to share / Forward messages over the internet. e. Phone calls (as in reading phone status): to disconnect the Bluetooth interface when AndFlmsg's audio is running through the Bluetooth interface AND a phone call comes in. This is to prevent the call's audio from going to the radio. f. Hardware controls (audio settings and recording): required for receiving and transmitting sound. g. Bluetooth administration: to redirect the sound via a Bluetooth interface. In your applications list you should now have an Flmsg logo called AndFlmsg.
