从广播接收器更改片段

Question

我的目标是使用广播接收器将 Activity B 的参数传递给 Activity A，效果很好。但是当我尝试从广播接收器更改 Activity A 中的 Fragment 时，它显示“在 onSaveInstanceState 之后无法执行此操作”

这是我的代码：

活动 B

val myintentdata = Intent("message_subject_intent")
            myintentdata.putExtra("imagefile", file.path)
            LocalBroadcastManager.getInstance(this@IdentitasActivity).sendBroadcast(myintentdata)
            finish()

活动 A

val mMessageReceiver: BroadcastReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent) {
            if(intent.hasExtra("penghuni")){
                val name = intent.getStringExtra("penghuni")
                Toast.makeText(this@NeinActivity, name, Toast.LENGTH_SHORT).show()
            }else if(intent.hasExtra("imagefile")){
                val name = intent.getStringExtra("imagefile")
                Toast.makeText(this@NeinActivity, name, Toast.LENGTH_SHORT).show()
                Glide.with(this@NeinActivity).load(name).into(identitas)
                supportFragmentManager.beginTransaction().replace(R.id.frame_layout, FragmentSelesai()).commit();
            }
        }
    }
    LocalBroadcastManager.getInstance(this)
        .registerReceiver(mMessageReceiver, IntentFilter("message_subject_intent"))

所有帮助对我来说意义重大。
