android小部件在几个小时后停止更新代码？

Question

我正在研究一个电池小部件，因此，当Intent.ACTION_BATTERY_CHANGED发生时，它会从小部件onRecive方法中从我可以从中获取其数据的位置收回问题是这样的，即整个过程会很好找，但是当时间流逝意味着您可以说小工具获得生活周围可以说4至5小时，Widget停止更新，此刻我使用textveiw来显示电池的数据，但一些小时后，小部件停止更新文本中的数据这里是代码

这里是插件 @Override 公共无效的onUpdate的更新方法（上下文语境，appWidgetManager appWidgetManager， INT [] appWidgetIds）{

context.getApplicationContext().registerReceiver(this, 
      new IntentFilter(Intent.ACTION_BATTERY_CHANGED)); 

    ComponentName cn = 
     new ComponentName(context, BatteryInfoActivity.class); 
    appWidgetManager.updateAppWidget(cn, this.views); 
} 

这里是上onRecive方法

@Override 
public void onReceive(Context context, Intent intent) { 
    String action = intent.getAction(); 

    if (action.equals(Intent.ACTION_BATTERY_CHANGED)) { 
     //Integer level = intent.getIntExtra("level", -1); 

     String mgs = "--"; 
     //String BatterInfo = "Level"+ intent.getIntExtra("level", -1)+ "/" + intent.getIntExtra("scale", -1); 
     Integer level = intent.getIntExtra("level", -1); 
     Integer scale = intent.getIntExtra("scale", -1); 
     Integer temp = intent.getIntExtra("temperature",-1); 
     Integer voltage = intent.getIntExtra("voltage", -1); 
     Integer health = intent.getIntExtra("health", -1); 
      boolean present = intent.getBooleanExtra("present", false); 
      Integer plugged = intent.getIntExtra("plugged", -1); 
      String technology = intent.getStringExtra("technology"); 
      Integer status = intent.getIntExtra("status",-1);  
      mgs = mgs + " Technology " + technology + "--"; 
      mgs = mgs + "Battery is Present " + present+"--"; 
      mgs = mgs + " level "+ level + "/" + scale + "--"; 
      mgs = mgs + "tempuratue" + temp + "--"; 
      mgs = mgs + "voltage"+ voltage + "--"; 

     this.views.setTextViewText(R.id.textView1, mgs); 
     ComponentName cn = 
      new ComponentName(context, BatteryInfoActivity.class); 
     AppWidgetManager.getInstance(context).updateAppWidget(cn, this.views); 
    } 
    super.onReceive(context, intent); 
}

不能注册从另一个BroadcastReceiver这样一个BroadcastReceiver。你不能在onReceive()中做任何事情，这些事情本身就会超过onReceive()的末尾。
