android - 无法动态注册接收者

Question

无法在启动时动态注册接收器。我没有 Activity 。而且我不想在服务中注册它。

在我注册另一个接收器的地方启动接收器:

package zzz.zzz.zzz;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;

public class AutoStart extends BroadcastReceiver
{   
    @Override
    public void onReceive(Context context, Intent intent)
    {   
        if ((intent.getAction() != null) && (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")))
        {
            IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
            filter.addAction(Intent.ACTION_SCREEN_OFF);
            BroadcastReceiver mReceiver = new ScreenReceiver();
            context.registerReceiver(mReceiver, filter);
        }
    }
}

我要注册的接收者:

package zzz.zzz.zzz;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class ScreenReceiver extends BroadcastReceiver 
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) 
        {
            // some code            
        }
        if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) 
        {
            // some code        
        }
    }
}

Answer 1

答案在错误消息中:IntentReceiver 组件不允许注册以接收 Intent 。您不能在现有的 BroadcastReceiver 中注册新的 BroadcastReceiver。
