kotlin中super.onCreate（saveInstanceState）中的illegalArgumentsException

Question

这是我的BaseActivity.java，我把它从java转换为kotlin：

package me.wcy.music.activity

abstract class BaseActivity : AppCompatActivity() {
    protected var mHandler = Handler(Looper.getMainLooper())

    override fun onCreate(savedInstanceState: Bundle?) {
        try{
            super.onCreate(savedInstanceState)
        }catch (e:Exception){
            e.printStackTrace()
        }


        setSystemBarTransparent()
        volumeControlStream = AudioManager.STREAM_MUSIC

            val playService = AppCache.playService ?: throw NullPointerException("play service is null")
            return playService
        }

    protected fun checkServiceAlive(): Boolean {
        if (AppCache.playService == null) {
            startActivity(Intent(this, SplashActivity::class.java))
            AppCache.clearStack()
            return false
        }
        return true
    }

    private fun setSystemBarTransparent() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            // LOLLIPOP解决方案

            finish()
            return true
        }
        return super.onOptionsItemSelected(item)
    }

    override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<String>, grantResults: IntArray) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        PermissionReq.onRequestPermissionsResult(requestCode, permissions, grantResults)
    }

    fun showSoftKeyboard(editText: EditText) {
        editText.isFocusable = true
        editText.isFocusableInTouchMode = true
        editText.requestFocus()
        mHandler.postDelayed({
            val inputManager = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
            inputManager.showSoftInput(editText, 0)
        }, 200L)
    }

    fun hideSoftKeyboard() {
        if (currentFocus != null) {

            inputManager.hideSoftInputFromWindow(currentFocus!!.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
        }
    }
}

我已经添加了＃34; a＆＃34; ？在onCreate中（saveInstanceState：Bundle） 但仍然有IllegalArgumentException：指定为非null的参数为null：方法kotlin jvm.internal.Intrinsics.checkParameterIsNotNull，参数savesInstanceState

这是我的日志
