#16

The app should be devided into GUI #16 and background service

#4 #5

Display a list of cached devices, like #18 and #19, but as own activity. Tap to check/uncheck a device

The documentation needs a UC diagram
Anforderungen Firechat.pdf

Sent messages should be encrypted, Depends on #3

Need icon for service. Will be displayed in notification bar when service is running.

If a device isnt in the DB yet, any attempt to create a chat history entry that involves this device will fail. Part of this is related to #8

The used version of android is 4.4, API level 19

Simple chat screen (activity)

Icon for paired/unpaired devices should be displayed in the GUI

SQLite for all sorts of saved data. #10 #12 #4 #5 #2 #3 #6 #7

Like #18 . Doesnt display nearby, but cached devices

git git git

The app needs a good looking graphical user interface

AES for encryption, RSA for key exchange. See #30 #31 #4 #5 #3

When a new message is sent, the sender extracted from the DB based on the ID is sometimes null.

Maybe related to #43.
Tested on Android 4.4

For internal and external messages alike. #12

See #19 . Service needs to be prepared

Nearby device list shows all cached devices instead of supported ones

Touch controls like selecting tabs or pressing the top right menu button doesnt work. Hardware Buttons also dont work.

Tested on Android 4.4

Needed for #34

The app needs a name, currently its just BluetoothChat

When calling updateDeviceLastSeen on a device thats not in the DB yet, a new device should be created. Currently it will be ignored

The listener and connection classes use the same basic architecture; merging them through inheritance might be possible. Priority is low though, since the current system works fine

start/stop background service (BGS)
make device discoverable
start/stop BGS connection listeners
delete chat history
delete cached devices
manage friends list
view and delete saved foreign public keys - (or as part of 'delete cached evices?)
view and generate new device key

After a new connection was made, the username(s) should be exchanged. The current json structure should support this

After a connection was made, encryption keys should be exchanged. The RSA public key is sent, then the AES key, which will be used for encryption
See #2, use same mechanism

GUI text is not being displayed on ANdroid 6, but it does work on Android 4.4

Received messages should be decrypted. Depends on #3, related #4

getDeviceID and getDeviceFriendlyName can be merged and should be

Try to open connection once in constructor

Only send ones

See #14 .

The icon needs to be made in this resolutions:
LDPI 36 x 36
MDPI 48 x 48
TVDPI 64 x 64
HDPI 72 x 72
XHDPI 96 x 96
XXHDPI 144 x 144
XXXHDPI 192 x 192
WEB 512 x 512 (only required for play store)

format png
#24

handleNewExternalMessage may receive mutliple, Json formatted strings at once. They are simply concatteneted. Need to be seperated

See #14. See #15. See #41.

The GUI should have a screen (or tab) for nearby devices. It shouldnt scan by itself, but provide interfaces to display the results from the service. A scrollable listview and a listviewadapter are needed for this.

Default language of the app is english. All programming should be english aswell

We need a documentation
#10 and #11

The ER diagram needs to be updated.
