Question

当我加载Android Studio并构建项目时，清单文件中出现了一个未解决的类。

       <activity
            android:name="com.google.zxing.client.android.CaptureActivity" //THIS IS WHERE THE ERROR POINTS TO
            android:configChanges="orientation|keyboardHidden"
            android:screenOrientation="landscape"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
            android:windowSoftInputMode="stateAlwaysHidden" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
            <intent-filter>
                <action android:name="google.zxing.client.android.SCAN" />

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

我还将其引用添加到我的build.gradle

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')    
    implementation 'com.android.support:support-v4:28.0.0-rc01'
    implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
    implementation 'com.journeyapps:zxing-android-embedded:3.0.2@aar'
    implementation 'com.google.zxing:core:3.3.2'
    //...More dependencies below
}

我尝试清理和重建，运行gradle文件，重新启动Android Studio，但仍然遇到未解决的类问题。我相信可能不再使用CaptureActivity。这只是猜测。我已经遍历了android开发者网站，看是否可以找到它，但没有运气。

编辑 Iforgot提到我在运行代码分析时首先看到了这一点。 分析->检查代码。在Android资源验证下。

更新！请阅读 进行此更改后，清理/重建项目时似乎遇到了问题

D:\Foo_Workspace\Library Build\Foo\mobile\src\main\AndroidManifest.xml:151:13-50 Error:

See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.

清单中的类错误，将其更改为

        <activity
        android:name="com.journeyapps.barcodescanner.CaptureActivity"
        android:configChanges="orientation|keyboardHidden"
        android:screenOrientation="landscape"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
        android:windowSoftInputMode="stateAlwaysHidden" 
        tools:replace="screenOrientation,android:theme" />

还可以更好地更新gradle依赖项

implementation ('com.journeyapps:zxing-android-embedded:3.6.0') { transitive = false }
implementation 'com.google.zxing:core:3.3.0'

与AndroidManifest.xml中的Unresolved类战斗
