waitFor

interface AdbServerConnectionOptions {
  unref?: boolean | undefined;
  signal?: AbortSignal | undefined;
}

declare class AdbServerClient {
  waitFor(
    device: AdbServerClient.DeviceSelector,
    state: "device" | "disconnect",
    options?: AdbServerConnectionOptions
  ): Promise<void>;
}

Wait for a device to be connected or disconnected. This method returns a Promise that resolves when the condition is met.

If the selector is usb, tcp or undefined, it won't tell which device is connected or disconnected.

Options

• unref: If the underlying connection is using Node.js net module, then unref the socket, so the process can exit even if the connection is still alive.
• signal: Stops the wait when the signal is aborted.

Equivalent ADB Command

adb wait-for[-TRANSPORT]-STATE

For example:

adb wait-for-device
adb wait-for-usb-device
adb wait-for-disconnect
adb wait-for-usb-disconnect
