発生している問題・エラーメッセージ

kotlin

1override fun onRequestPermissionsResult(2 requestCode: Int, permissions: Array<String>, grantResults:3 IntArray) {4 if (requestCode == REQUEST_CODE_PERMISSIONS) {5 if (allPermissionsGranted()) {6 startCamera()7 } else {8 Toast.makeText(this,9 "Permissions not granted by the user.",10 Toast.LENGTH_SHORT).show()11 finish()12 }13 }14}15

上記コードのonRequestPermissionsResultメソッドのところで赤の下線が出る。エミュレータでの実行は通るがすぐにアプリが落ちてしまう

kotlin

1override fun onRequestPermissionsResult(2 requestCode: Int, permissions: Array<String>, grantResults:3 IntArray) {4 super.onRequestPermissionsResult(requestCode, permissions, grantResults)5 if (requestCode == REQUEST_CODE_PERMISSIONS) {6 if (allPermissionsGranted()) {7 startCamera()8 } else {9 Toast.makeText(this,10 "Permissions not granted by the user.",11 Toast.LENGTH_SHORT).show()12 finish()13 }14 }15 }

上記のようにエディタで指示されたように書き換えてもすぐにアプリが落ちてしまう。

試したこと

onRequestPermissionsResultの代わりにonActivityResultに変更して試しても起動することがなかった。
