i have Nexus 5 phone and galaxy Gear(null_17 ROM).
Nexus 5 with KitKat 4.4.2
Galaxy Gear with V700XXUAMK7 with NULL_17 ROM
and watchstyler 1.0.9 (working) with Casio Skin
At first i installed gearmanagerstub.apk
after i just bring "gear manager 1.6 111801.apk" and renamed to "gear manager 1.6 111801.zip"
opened and bring all file in the folder "preinstalledapk"
and run all one by one excepted for "samusic" and "saweather" because fail to installing(but is ok).
after all manual apk installed also installed "gear manager 1.6 111801.apk"
and opened gear manager and start the gear and pairing it. (2 or 3 time but making same test and check and at final running)
if you come from old pairing with other gear manager version example 1.5 or 1.4 etc... just from your sdcard delete the folder ".BManager_backup"
for fix the notification i also installed ATNmanager 1.2.2.apk on the phone, and in the gear i already sended the version of "ATNmanager 22.214.171.124_pre"(only the watch.apk file inside) and i receive all notify on gear by this apps and working fine.
remeber to go in setting->security->allow ATNmanager to read notification
up to now
camera(make and send directly to the phone in gallery)
call and receive it.
voice record (record and send on phone, but play with file manager in "sdcard/Sounds/Galaxy_Gear/your recording file"
For me is a good Result
