我知道已经有很多问题了。我已经经历了所有这些,但我仍然无法解决我的问题。
我被要求扩展一个已经存在的 android 应用程序,它基于PhoneGap
. 我从一个 repo 中查看了源代码,并意识到第一个开发人员包含了library
一些dependency
. 我按照这里的说明进行操作,构建的core
不是ZXing
任何build.xml
的ant
。
我浏览了XZing Getting started中的说明,构建我自己的core-2.3.jar
尝试包含,但失败了。与core.jar
从页面部署的就绪相同
我在文件夹中包含了罐子/libs
,导入的是一个external jar
,没有任何效果。我每次都收到以下错误:

清单声明如下所示:
<!-- ZXing activities -->
<activity android:name="com.google.zxing.client.android.CaptureActivity"
android:screenOrientation="landscape"
android:configChanges="orientation|keyboardHidden"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden"
android:exported="false">
<intent-filter>
<action android:name="com.phonegap.plugins.barcodescanner.SCAN"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
<activity android:name="com.google.zxing.client.android.encode.EncodeActivity"

<intent-filter>
<action android:name="com.phonegap.plugins.barcodescanner.ENCODE"/>

那么,任何人都有任何想法,为什么我不能包括CaptureActivity
?
