Android的工作室无法导入WearableExtender NotificationManagerCompat和RemoteInput [英] Android studio unable to import WearableExtender NotificationManagerCompat and RemoteInput

问题描述

我有一个项目类以下的进口：

I have a project class with the following imports:

import android.app.Activity;
import android.app.Fragment;
import android.app.Notification;
import android.app.PendingIntent;
import android.app.RemoteInput;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.NotificationCompat.Action;
import android.support.v4.app.NotificationCompat.WearableExtender;
import android.support.v4.app.NotificationManagerCompat;
import android.support.v4.app.RemoteInput;
import android.text.Html;
import android.util.Log;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;

在机器人工作室以下三个弹出一个无法解决符号错误：

In android studio the following three bring up a 'cannot resolve symbol' error:

import android.support.v4.app.NotificationCompat.WearableExtender;
import android.support.v4.app.NotificationManagerCompat;
import android.support.v4.app.RemoteInput;

Wierdly，在android.support.v4.app进口的NotificationCompat和NotificationCompat.Action是成功的。

Wierdly, the import for NotificationCompat and NotificationCompat.Action in android.support.v4.app are successful

import android.support.v4.app.NotificationCompat;
import android.support.v4.app.NotificationCompat.Action;

我曾尝试使用基于Eclipse相同的进口（指向相同SDK机器人工作室）和相同的工作，没有任何错误奔去。

I have tried to use the same imports on eclipse (pointing to the same SDK as android studio) and the same worked and ran without any errors.

我也试过<一个href=\"http://stackoverflow.com/questions/24406225/auto-import-not-working-for-android-classes-in-android-studio\">Minto's无效缓存解决方案 /重启机器人工作室......我的SDK是最新的在发帖的时间。感谢您的帮助提前

I've also tried Minto's solution of invalidating caches/restarting android studio ...my SDK is up to date as at the time of posting. Thanks for any help in advance

推荐答案

请确保您把下面进入您的应用程序的build.gradle文件，以提供必要的依赖：

Make sure that you put the following entry into your application's build.gradle file to provide the necessary dependencies:

dependencies {
    compile 'com.android.support:support-v4:20.0+'
}

版本号是很重要的，如果你指定一个旧版本，它会缺少新的通知code为身打扮。

The version number is important, if you specify an older version it will be missing the new Notification code for wearables.
