i am trying to connect two android devices using WIFI direct and i was successful. But the problem is the second device has to accept the a connection prompt after the other device initiates the connection. It is undesirable for what i am trying to achieve. I saw a few post here in stack overflow itself saying that currently its not possible. But came across an app called SUPERBEAM which user WIFI direct but without the prompt. A search in google gave me the following link from xda forum which says
SuperBeam creates an access point using Android's WiFi direct API's. This essentially works like hotspot mode in old devices, but it is guaranteed to work on newer devices like Nexus 7. Moreover, this mode allows older devices to connect and receive files without having to support WiFi direct's peer-to-peer connections and, more importantly, it gets rid of the annoying "accept connection" prompt.
But no where i found information on how to implement this. Can anybody help me. Here is the link
You could indeed simply use the createGroup function from the API to create a group, which also makes the access point. The first problem here is that the access point name & password are set automatically, and you can not change them.
So, you do need to pass the info to the connecting party, and for this, I would suggest using the local service advertising, and using the instance name there.
This can be achieve using Xposed framework. You need add the code and install the App. The phone needs to be rooted in order for it to work. I have tested it on multiple Samsung phones and it works.
