open class SecureFragment : LogLifecycleFragment() {override fun onResume() {super.onResume()if (!BuildConfig.DEV) {requireActivity().window.setFlags(WindowManager.LayoutParams.FLAG_SECURE,WindowManager.LayoutParams.FLAG_SECURE)}}override fun onPause() {super.onPause()if (!BuildConfig.DEV) {requireActivity().window.clearFlags(WindowManager.LayoutParams.FLAG_SECURE)}} }
