Can I call adb tcpip 5555 by itself

[vanhcm20]

Hi, I need to find a way to use the dadb library to call commands directly. I've managed to do it by calling adb with wireless debugging via code below, but if I don't enable adb tcpip 5555 beforehand using my PC, I get a connection refused error.

AdbKeyPair keyPair = loadOrCreateKeyPair(appContext);
        try (Dadb dadb = Dadb.Companion.create(host, port, keyPair)) {
            AdbShellResponse response = dadb.shell(command);
            String output = response.getAllOutput();
            return output == null ? "" : output.trim();
        }

So, is there a way I can enable adb tcpip 5555 without connecting to a PC? I know I can root my device and call the adb service, but I don't want to use that method.

@Leland-Takamine @tiann @amanjeetsingh150 any ideas?

You want to cross the river, but you refuse to take a boat and also refuse to swim, is that right?

Hi @tiann
First, thank you for the feedback, as well as for this great library.

I know it sounds silly. To be honest, I'm quite new to Android programming, and I need adb for a function in my app, but since I don't always have a PC available, that's why I'm asking. I thought about using Wireless Debugging's Pairing Code, but I couldn't find a function to use with that Pairing Code. Or it would be even better if you could suggest a way to do it without using Pairing Code.

You can try this library: https://github.com/MuntashirAkon/libadb-android?tab=readme-ov-file#wireless-debugging it supports pair code.

I don’t think you can use adb without a pairing code, without using a computer, and without rooting the phone; adb has very high privileges, and if an ordinary app could just enable it at will, that would be a disaster for users.
