bug(adb): UAD-ng doesn't start when ADB isn't installed

[AnonymousWP]

Describe the bug

When ADB is absent on a system, UAD-ng doesn't start at all. It also doesn't tell me ADB isn't installed.

Expected behavior

I expect UAD-ng to start and inform me that ADB is required but isn't present/installed.

You have a solution?

Implement a check when starting UAD-ng.

Yeah but my point is that we need something more verbose.

[AnonymousWP]

It's not just about being verbose. UAD-ng just doesn't start at all and the user is not notified by it, unless the user checks logs. That's a very user-unfriendly way.

Would something like this work?

match command.output() {
    Err(e) => {
        // Log the error for debugging purposes
        error!("ADB: {}", e);
        error!("ADB was not found");

        // Display error message to the user using a message box
        message_box(None, "Error", "ADB was not found. Please make sure ADB is installed and accessible.", MessageBoxButtons::Ok, MessageBoxIcon::Error);

        // Exit the program
        std::process::exit(1);
    }
    // Handle Ok arm here if needed
}
