scrcpy Integration in a Tauri App — Android Screen Mirroring on Mac

The article describes how to integrate scrcpy, an open-source Android screen mirroring tool, into a Tauri app for Mac. It covers launching scrcpy from Rust code, bundling it as a universal binary within the app's resources, detecting when the mirror window closes, and supporting multiple Android devices via ADB serial selection. The author tested the implementation on an 8-year-old MacBook Air while shipping seven Mac apps as a solo developer.

All tests run on an 8-year-old MacBook Air. All results from shipping 7 Mac apps as a solo developer. No sponsored opinion. HiyokoKit includes Android remote control via scrcpy. Launching and managing scrcpy from a Tauri app has specific challenges. Here's how I handle it. What scrcpy is scrcpy is an open-source tool that mirrors and controls an Android device screen over ADB. It's the best free option for Android screen mirroring on Mac — fast, low latency, no app required on the device. Launching scrcpy from Rust rustuse std::process::{Command, Child}; use std::sync::Mutex; pub struct ScrcpyProcess { child: Option, } impl ScrcpyProcess { pub fn start &mut self, device serial: &str, max size: u32, bit rate: &str, - Result< , AppError { let child = Command::new "scrcpy" .args "--serial", device serial, "--max-size", &max size.to string , "--video-bit-rate", bit rate, "--window-title", "Android Mirror", "--no-audio", .spawn .map err |e| AppError::Scrcpy e.to string ?; self.child = Some child ; Ok } pub fn stop &mut self { if let Some mut child = self.child.take { child.kill .ok ; } } pub fn is running &mut self - bool { if let Some child = &mut self.child { child.try wait .map |s| s.is none .unwrap or false } else { false } } } Bundling scrcpy scrcpy needs to be available on the user's machine or bundled with your app. I bundle it in app resources as a universal binary: json{ "bundle": { "resources": "bin/scrcpy", "bin/adb" } } At runtime, get the resource path: rustlet scrcpy path = app handle .path .resource dir .unwrap .join "bin/scrcpy" ; Detecting when scrcpy exits scrcpy exits when the user closes the mirror window. Detect this to update your UI: rust// Poll in background tokio::spawn async move { loop { tokio::time::sleep Duration::from secs 1 .await; let running = { let mut proc = scrcpy state.lock .unwrap ; proc.is running }; if running { app handle.emit "scrcpy-stopped", .ok ; break; } } } ; Multiple device support scrcpy's --serial flag selects a specific device when multiple are connected. Get the serial from adb devices and pass it explicitly: rustasync fn get device serial - Result { let output = Command::new "adb" .args "devices" .output .await?; let stdout = String::from utf8 lossy &output.stdout ; stdout.lines .skip 1 .find |l| l.contains "device" .and then |l| l.split whitespace .next .map |s| s.to string .ok or AppError::Device "No device found".into } If this was useful, a ❤️ helps more than you'd think — thanks Hiyoko PDF Vault → https://hiyokomtp.lemonsqueezy.com/checkout X → @hiyoyok
