接收器未注册的异常错误？ [英] Receiver not registered exception error?

问题描述

在我的开发人员控制台不断有人举报，我不能对任何手机，我有重现错误。一人留了消息，说他得到它，当他们试图打开我的电池服务的设置界面。正如你可以从错误中看到它说，该接收器未注册。

In my developer console people keep reporting an error that I cannot reproduce on any phone I have. One person left a message saying he gets it when they try to open the settings screen of my battery service. As you can see from the error it says that the receiver is not registered.

我是登记在我的onCreate

I register is in my onCreate

@Override
public void onCreate(){
    super.onCreate();
    SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(this);
    IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
    filter.addAction(Intent.ACTION_POWER_CONNECTED);
    filter.addAction(Intent.ACTION_POWER_DISCONNECTED);
    registerReceiver(batteryNotifyReceiver,filter);
    pref.registerOnSharedPreferenceChangeListener(this);
}

注销在的onDestroy，也有preference监听器

Unregister in onDestroy and also with a preference listener

    @Override
public void onDestroy(){
    super.onDestroy();
    unregisterReceiver(batteryNotifyReceiver);

}

这是我在服务接收器

and this is my receiver in the service

private final class BatteryNotifyReceiver extends BroadcastReceiver {

    boolean connected;
    @Override
    public void onReceive(Context context, Intent intent) {

        SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context); 
        SharedPreferences.Editor edit = prefs.edit();

            updatePreferences(prefs);

        level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);



        if(intent.getAction().equals(Intent.ACTION_POWER_CONNECTED)){
            connected = true;
        }else if(intent.getAction().equals(Intent.ACTION_POWER_DISCONNECTED)){
            connected = false;
        }else if(intent.getAction().equals(Intent.ACTION_BATTERY_CHANGED)){

                if(level < lastLevel){
                    if(level > 40){
                        edit.putBoolean("first", false).commit();
                        edit.putBoolean("second", false).commit();
                        edit.putBoolean("third", false).commit();
                       edit.putBoolean("fourth",false).commit();                            
                        edit.putBoolean("fifth", false).commit();
                    }
                    if(level == 40){
                        if(!first){
                        notification(context,battColor,battBlink,battVib,battSound);

                        edit.putBoolean("first", true).commit();
                        }
                    }else if(level == 30){
                        if(!second){
                        notification(context,battColor,battBlink,battVib,battSound);

                        edit.putBoolean("second", true).commit();
                        }
                    }else if(level == 20){
                        if(!third){
                        notification(context,battColor,battBlink,battVib,battSound);

                        edit.putBoolean("third", true).commit();
                        }
                    }else if(level == 15){
                        if(!fourth){
                        notification(context,battColor,battBlink,battVib,battSound);

                        edit.putBoolean("fourth", true).commit();
                        }
                    }else if(level == 5){
                        if(!fifth){
                        notification(context,battColor,battBlink,battVib,battSound);

                        edit.putBoolean("fifth", true).commit();
                        }
                    }
                lastLevel = temp;
            }
        }           

        Intent i = new Intent(context,BatteryNotifyReceiver.class);
        context.startService(i);
    }       
}

任何知道他们为什么会得到这个错误？

any idea why they would be getting that error?

推荐答案

你的问题的根源就坐落于此：

The root of your problem is located here:

 unregisterReceiver(batteryNotifyReceiver);

如果接收方已经注册的（大概在code，你并没有包括在这个岗位），或者未注册，然后打电话 unregisterReceiver 抛出抛出：IllegalArgumentException 。你的情况，你需要只是把特殊的try / catch这个异常，而忽略它（假设你不能或不想控制你调用次数 unregisterReceiver 在同一recevier）。

If the receiver was already unregistered (probably in the code that you didn't include in this post) or was not registered, then call to unregisterReceiver throws IllegalArgumentException. In your case you need to just put special try/catch for this exception and ignore it (assuming you can't or don't want to control number of times you call unregisterReceiver on the same recevier).
