does not exists!

Error message

${executablePath} does not exists!

What it means

getServerRunnerCommand builds the command line to launch the AM server based on the mode of operation; it requires a specific executable file (root su binary, adb executable, or applet) to exist on disk. If the resolved executable's path does not exist, an UnsupportedOperationException naming the missing path is thrown.

Solutions

1. Call ServerConfig.init(...) first so binaries are extracted to their expected paths
2. Check new File(executable.getPath()).exists() for the mode-specific binary before building the command
3. Switch the mode of operation (Ops.setMode) to one whose executable exists, e.g. ADB mode on non-rooted devices
4. Verify the su binary exists (which su / LibUtils/BusyBox check) before selecting root mode

Example fix

// before
String[] cmd = ServerConfig.getServerRunnerCommand(...);
// after
if (!new File(ServerConfig.getExecutablePath(mode)).exists()) {
    ServerConfig.init(context, false); // extract binaries first
}
String[] cmd = ServerConfig.getServerRunnerCommand(...);

File exe = new File(executablePath);
if (!exe.exists() || !exe.canExecute()) {
    // extract assets via ServerConfig.init or switch mode
}

try {
    String[] cmd = ServerConfig.getServerRunnerCommand(...);
} catch (UnsupportedOperationException e) {
    // e.getMessage() names the missing executable; re-extract or change mode
    ServerConfig.init(context, true);
}

When it happens

Trigger: Requesting a server runner command while the expected executable — e.g. the 'su' binary for root mode, the copied applet jar, or the adb executable — is absent from its resolved absolute path.

Common situations: Running on a non-rooted device while root mode is selected, Magisk/su not installed, the app's binary assets not yet extracted (init not called), or an architecture without a bundled applet.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
