下面是类文件,它是: 创建一个名为
autoanswerbootceiver.java的文件
package com.example.autoanswer; // Just change the package name to yours
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class AutoAnswerBootReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
AutoAnswerNotifier notifier = new AutoAnswerNotifier(context);
notifier.updateNotification();
}
}
这个自动应答引导接收器在哪里
?错误是正确的。您没有名为AutoAnswerBootReceiver的类我理解这些错误…谢谢。。。。
