Question

我试图将示例活动添加到现有项目中。该项目与Gradle编译良好，但在我将活动声明添加到清单后，已编译的清单在http://schemas.android.com/apk/res/android处为红色，其中包含未注册＆＃39; URI的浮动消息。

清单：

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

<uses-permission android:name="android.permission.INTERNET"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >

            <action android:name="android.intent.action.MAIN" />

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

    <activity
        android:label="@string/action_bar_demo_name"
        android:name=".ActionBarDemoActivity"
        android:configChanges="keyboardHidden|orientation|screenSize"
        android:screenOrientation="sensorLandscape">
        <meta-data android:name="@string/minVersion" android:value="11"/>
        <meta-data android:name="@string/isLaunchableActivity" android:value="true"/>
    </activity>

</application>

添加的活动是从YouTube API示例项目中获取的actionBarDemoActivity。

控制台错误与minVersion有关：错误：（33,31）找不到与给定名称匹配的资源（名称＆＃39;值为＆＃39; @ string / minVersion＆＃39;）。

看起来只是一种症状。

Answer 1

确保minVersion中包含名为isLaunchableActivity和string.xml的字符串。

此外，这些字符串应具有唯一的名称。所以你应该使用你的包名。因此，它们的名称类似于com.example.YouTuber.minVersion和com.example.YouTuber.isLaunchableActivity。

另见http://developer.android.com/guide/topics/manifest/meta-data-element.html
