APK Install and App Manager in Rust + Tauri — Building ADB Tools

#tauri #rust #programming #android

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 APK installation and an Android app manager. Both use ADB under the hood. Here's the implementation.

APK installation 

#[tauri::command]
async fn install_apk(apk_path: String) -> Result<String, AppError> {
    let output = tokio::process::Command::new("adb")
        .args(["install", "-r", &apk_path]) // -r = reinstall if exists
        .output()
        .await?;

    let stdout = String::from_utf8_lossy(&output.stdout);
    let stderr = String::from_utf8_lossy(&output.stderr);

    if stdout.contains("Success") {
        Ok("Installation successful".into())
    } else {
        let error = if stderr.contains("INSTALL_FAILED_VERSION_DOWNGRADE") {
            "Cannot install older version over newer. Use -d flag to downgrade."
        } else if stderr.contains("INSTALL_FAILED_ALREADY_EXISTS") {
            "App already installed. Use reinstall option."
        } else {
            "Installation failed"
        };
        Err(AppError::Adb(error.into()))
    }
}

Parse the specific error codes — generic "installation failed" isn't useful to users.

App list 

#[derive(Serialize)]
pub struct AppInfo {
    package_name: String,
    is_system: bool,
}

#[tauri::command]
async fn list_apps(include_system: bool) -> Result<Vec<AppInfo>, AppError> {
    let flag = if include_system { "-l" } else { "-3" }; // -3 = third-party only

    let output = tokio::process::Command::new("adb")
        .args(["shell", "pm", "list", "packages", flag])
        .output()
        .await?;

    let apps = String::from_utf8_lossy(&output.stdout)
        .lines()
        .filter_map(|line| {
            line.strip_prefix("package:").map(|pkg| AppInfo {
                package_name: pkg.trim().to_string(),
                is_system: !include_system,
            })
        })
        .collect();

    Ok(apps)
}
Enter fullscreen mode Exit fullscreen mode

App uninstall 

#[tauri::command]
async fn uninstall_app(package_name: String) -> Result<(), AppError> {
    let output = tokio::process::Command::new("adb")
        .args(["uninstall", &package_name])
        .output()
        .await?;

    if String::from_utf8_lossy(&output.stdout).contains("Success") {
        Ok(())
    } else {
        Err(AppError::Adb(format!("Failed to uninstall {}", package_name)))
    }
}
Enter fullscreen mode Exit fullscreen mode

Clipboard sync between Android and Mac 

#[tauri::command]
async fn push_clipboard_to_android(text: String) -> Result<(), AppError> {
    tokio::process::Command::new("adb")
        .args(["shell", "am", "broadcast", "-a", "clipper.set", "-e", "text", &text])
        .status()
        .await?;
    Ok(())
}

#[tauri::command]
async fn get_android_clipboard() -> Result<String, AppError> {
    let output = tokio::process::Command::new("adb")
        .args(["shell", "am", "broadcast", "-a", "clipper.get"])
        .output()
        .await?;

    // Parse broadcast result for clipboard content
    let stdout = String::from_utf8_lossy(&output.stdout);
    extract_clipboard_from_broadcast(&stdout)
}
Enter fullscreen mode Exit fullscreen mode

Note: clipboard sync via ADB requires Clipper or similar app on the Android device.

Error handling for ADB not found 

fn check_adb_available() -> Result<(), AppError> {
    Command::new("adb")
        .arg("version")
        .output()
        .map_err(|_| AppError::Adb(
            "ADB not found. Please install Android Platform Tools.".into()
        ))?;
    Ok(())
}
Enter fullscreen mode Exit fullscreen mode

Check on launch, not on first use. Users should know immediately if ADB is missing.

TL;DR: Building ADB tools in Rust + Tauri: parse specific error codes for APK install (not just "failed"), use pm list packages -3 for third-party apps, and check ADB availability on launch. Clipboard sync needs Clipper on the Android side.

If this was useful, a ❤️ helps more than you'd think — thanks!
