Problem: AutoStart On Boot Up causing classcastexception..
I am doing Location based application , I want to run the app whenever the phone bootup,So that my app will be running continuously, I just want to start the service as soon as the phone loads all the service.
ブロードキャストレシーバーメソッドを作成し、mainfest xml でレシーバーと許可を設定しました。次のコードを書いていますが、ランタイムエラーが発生しています。アクティビティを削除して実行しようとしましたが、エラーが発生しました。解決策を教えてください。
