Make production build more quiet?

[m1ga]

first: yes it is very easy/quick to check if it is an Appcelerator app. eg. use Dexplorer and look at the AndroidManifset.

Should the production build not log any Ti.API.* infos? E.g. there is always a "powered by" message. Android will only hide Ti.API.debug in production builds so it is always visible if you don't remove it on your own. I think maybe it shouldn't log anything there, if you want to get some logs: create a debug version 😄
There was ti-stealth or other workarounds to create a custom log function but for security reasons a store build should not contain any log output that can be easily spotted with adb logcat

Sources for the logging inside the SDK: https://github.com/appcelerator/titanium_mobile/blob/master/android/runtime/v8/src/native/modules/APIModule.cpp

Yes, this was intentional for production builds. Just like how the native logging functions still work for release builds.

If you want to disable all logging functions for production/release builds, then add a new script file to your project named DisableLogging.bootstrap.js with the below code. This will replace all logging functions to make them no-op. Note that files ending with *.bootstrap.js will be loaded by Titanium before the app.js or alloy.js (it's an undocumented feature). Also note that this will not block the "Powered by Titanium" log message since bootstrap scripts are loaded afterwards, but this was the intent on our end.

// Disable logging for release/production builds.
if (DIST_STORE) {
	const emptyFunction = () => {};
	Ti.API.info = emptyFunction;
	Ti.API.warn = emptyFunction;
	Ti.API.error = emptyFunction;
	Ti.API.debug = emptyFunction;
	Ti.API.trace = emptyFunction;
	Ti.API.timestamp = emptyFunction;
	Ti.API.log = emptyFunction;
	console.log = emptyFunction;
	console.warn = emptyFunction;
	console.error = emptyFunction;
	console.debug = emptyFunction;
	console.trace = emptyFunction;
}

Does this help?

oh, thats a nice feature 👍 That will help a lot and is a very clean solution. Thanks

Happy to help!

FYI: Titanium loads all bootstrap scripts on app startup here...
https://github.com/appcelerator/titanium_mobile/blob/master/common/Resources/ti.main.js#L31

The CLI generates a bootstrap.json during the build which provides a list of all files ending with .bootstrap.js in the app project's file tree... including modules. This JSON helps with fast startup times.

We use this feature with our ti.playservices module. It adds a bootstrap script which checks if Google Play Services is installed and using the expected version on startup. If not installed/updated, then it will show a dialog asking the end-user to install/update it before procedding to load the "app.js".
