Executing requests causes `Connection refused: /127.0.0.1:5037`

[pacjo]

Describe the bug
Hi, I'm trying to query adb devices, pair and connect to them, but I'm having troubles even with the first part. Any request I execute ends in io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: /127.0.0.1:5037 exception. This happens both on an emulator and a real device (both connected and disconnected from adb).

To Reproduce
I'm using following code similar to the example provided in docs.

StartAdbInteractor().execute()
val adb = AndroidDebugBridgeClientFactory().build()
val devices = adb.execute(request = ListDevicesRequest())

Log.d(TAG, "devices: $devices")

the same happens when running FetchDeviceFeaturesRequest. I tried changing the port with serverPort argument of StartAdbInteractor().execute() to 5038 and providing device serial to the feature request manually - none of those changed the behavior.

Expected behavior
No connection error would be thrown. Devices and features requests would run properly.

Seems like you're running from android device itself. Android doesn't have an adb server, you need to connect to some external machine that has an adb server running

[pacjo]

Alright, but wouldn't the same happen on any other os without adb available? Does the server always need to be installed manually?

[Malinskiy]

Yes, ADB server is always required. Adam is a client for this server (mostly), so it's required.

[pacjo]

Ok. Is the server just the adb binary from platform-tools or is it something else? I saw libadb.so in some projects like this.

[pacjo]

Hi, I learned that including executables from jnilibs requires adding android:extractNativeLibs="true" to the application tag in android manifest. After doing that I can see the library being available from the emulator, but I'm having issues interacting with it.

I'm able to consistently cause a crash by starting StartAdbInteractor with following code:

val binary = File(context.applicationInfo.nativeLibraryDir + "/libadb.so")
StartAdbInteractor().execute(adbBinary = binary)

I wouldn't bother you with this, but when running the executable manually it looks like it's working fine (this is running the same file on the same emulator):

I'll try to obtain a libadb.so with debug symbols present. In the meanwhile I wanted to ask if there's a way to get some logs from your library, since right now this stacktrace is all I got.
