Thank you for your replies. My emulator doesn’t have Google Play app. So I tried to install the .apk file of Samsung Accessory Service and I got this error:
Now I get it. Samsung phones have Samsung Accessory Service installed automatically when user connects to a watch from Galaxy warable android app.
So on non-samsung devices (android phones like Huawei, oppo,…), if user install Galaxy wearable and connects to galaxy watch, Samsung Accessory Service will be automatically installed too (by the galaxy wearable). And I don’t need to worry about compatibility on non-samsung devices anymore?
Is that correct?
I asked this because when I tried uninstalling Samsung Accessory Service from my galaxy phone, my watch was disconnected. Then I opened Galaxy wearable and press “connect” again, I found out that Samsung Accessory Service is silently installed.
Thanks in advance.
