I keep getting an error related to applyCommandsSync.

Lines of code from the AppNavigator file lines 27 to 46.

    override fun applyCommands(commands: Array<out Command>) {
        mainHandler.post {
            applyCommandsSync(commands)
        }
    }

    protected open fun applyCommandsSync(commands: Array<out Command>) {
        fragmentManager.executePendingTransactions()

        //copy stack before apply commands
        copyStackToLocal()

        for (command in commands) {
            try {
                applyCommand(command)
            } catch (e: RuntimeException) {
                errorOnApplyCommand(command, e)
            }
        }
    }

My code in ParentActivity lines 78 to 85.

    private val navigatorHolder = provideNavigatorHolder()

    private val navigator: Navigator = object : AppNavigator(this, R.id.container_parent) {
        override fun applyCommandsSync(commands: Array<out Command>) {
            super.applyCommandsSync(commands) - this ParentActivity.kt:82
            supportFragmentManager.executePendingTransactions()
        }
    }

What could be the problem?

override fun applyCommands(commands: Array) {
mainHandler.post {
applyCommandsSync(commands)
}
}
Run this on UI thread with using runOnUiThread(runnable);
The problem should get solved.

applyCommandsSync(commands)

Ok. I try this tomorrow.

Your solution didn't help.
