从命令行运行时出现此错误消息:

[javac]E:\...\MainActivity.java:19: Error: Package R does not exist                      
[javac] setContentView(R.layout.activity_main);

我已将import com.***.R;添加到文件MainActivity.java。 这是xml文件:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.***">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:persistent="true"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service android:name=".JmfService"
            android:enabled="true"/>

    </application>

我已尝试ant cleanrebuild project等等。 当点击菜单按钮来构建项目时,我得到了BUILD SUCCESSFUL
