Question

尝试使用闹钟管理器来安排我的代码＆＃39;每天运行，我按照教程，并尝试适应我的代码。

两点：

1）我是否在逻辑上以正确的方式使用报警管理器，在哪里放置受报警管理器影响的代码以及不正常运行的代码，以及那里的一些信息。

2）尝试并修复日志cat错误，因为您可能已经意识到我是Android开发的新手，所以我正在努力修复/找到错误。 - 任何有关logcat查找错误的见解也很有用。

这是我的＆＃39; MainACtivity.java＆＃39;：

public class MainActivity extends Activity {

    private PendingIntent pendingIntent;

    @Override   protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);         setContentView(R.layout.home);

                Intent myIntent = new Intent(MainActivity.this, Alarm.class);
                pendingIntent = PendingIntent.getService(MainActivity.this, 0, myIntent, 0);



        AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);



        Calendar calendar = Calendar.getInstance();

        calendar.setTimeInMillis(System.currentTimeMillis());

        calendar.add(Calendar.SECOND, 10);

        alarmManager.set(Calendar.HOUR_OF_DAY, 0, pendingIntent);

        alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pendingIntent);         // time set up is unsuccessful in earlier versions

            }       @Override   public boolean onCreateOptionsMenu(android.view.Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        super.onCreateOptionsMenu(menu);        getMenuInflater().inflate(R.menu.main, menu);       return true;
            }



}

这是我的＃Alarm; java＆＃39;：

public class Alarm extends Service{



public static final String MyPREFERENCES = "crntPrefs";

    private Random rand = new Random();
    int[] ids = {R.string.word1, R.string.word2 //etc....};

    SharedPreferences sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedpreferences.edit();



    public void onStart(Intent intent, int startId) {
        {
            //my code
    }

}

logcat的：
