Question

我一直试图在我的onCreate方法中让一个闹钟管理员调用我的班级BatteryPost：

BatteryPost.java：

public class BatteryPost extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {
    HttpClient httpclient = new DefaultHttpClient();
    final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
    String batteryText = prefs.getString("battery", null);
    String id = prefs.getString("id", null);
    String URL = "http://mysite.com/checkin/index.php?device_uid="+id+"&bat="+batteryText; 
    {
    try{
    String uri = URL.replace(" ", "%20"); //replace spaces with %20
    Log.d("Checkin", uri);
    HttpPost httppost = new HttpPost(uri); //post object
    @SuppressWarnings("unused")
    HttpResponse response = httpclient.execute(httppost); //execution
    } catch (ClientProtocolException e) {
        Log.d("Checkin", "ClientProtocolException");
    } catch (IOException i) {
        Log.d("Checkin", "IOException");
    }
   }

 }
}

我的onCreate（）中应该被AlarmManager击中：

public void onCreate(Bundle savedInstanceState) {
        /*
         * Our onCreate block...
         */
        super.onCreate(savedInstanceState); 
        Context context = getApplicationContext();  
        setContentView(R.layout.activity_main);
        Button submit = (Button)findViewById(R.id.submitButton);
        submit.setOnClickListener(submitListener); //Initialization of the view and objects
        this.registerReceiver(this.mBatInfoReceiver, 
        new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.MINUTE, 1);
        Intent intent = new Intent(context, BatteryPost.class);
        PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
        am.setInexactRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 600000, sender);

}

当我按下按钮时，我注册了手动更新电池电量到服务器，因此值正确存储，但是AlarmManager无法每分钟调用一次BatteryPost（只需每分钟进行测试，之后会更长））。

我一直在寻找SO上的其他帖子试图找到类似的代码，但实现这一点已经变得棘手了。

感谢。

我注意到的第一件事是你要检查600000毫秒。这不是60秒，而是600，或者换句话说，10分钟。这可能是问题吗？

广播接收器未被调用
