我一直在尝试让我的类BatteryPost在我的 onCreate 方法中被警报管理器调用：
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");
}
}
}
}
在我的 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);
}
当我点击按钮时，我注册手动将电池电量更新到它工作的服务器，因此这些值被正确存储，但 AlarmManager 无法每分钟调用 BatteryPost（只是每分钟进行测试，之后会更长）。
我一直在查看 SO 上的其他帖子以尝试找到类似的代码，但实现这一点变得很棘手。
谢谢。
