Question

我的Android应用程序有问题。以下是我收到的错误消息：

11-06 18:15:02.606: E/AndroidRuntime(2424): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{de.wiedemann.mobile/de.wiedemann.mobile.WIEDEMANN}: java.lang.ClassNotFoundException: Didn't find class "de.wiedemann.mobile.WIEDEMANN" on path: DexPathList[[zip file "/data/app/de.wiedemann.mobile-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

我尝试了以下事项：

删除R.java
清理项目
检查项目首选项下的所有依赖项 - ＆gt;订单和出口
取消选中＆＃34;是图书馆＆＃34;在Tab＆＃34; Android＆＃34;在项目首选项
重启Eclipse
尝试其他工作区

没有任何作用。任何人都知道这个错误是如何解决的，以及我如何解决它？

The Manifest：

修改

只需将活动标记中的 android：name 重命名为 wiedemann.app.WIEDEMANN 即可。看完截图后 http://imgur.com/oYTN4ZN
我突然意识到我之前提出了错误的答案。

或者只需将其粘贴到 manifest.xml ：
中
<?xml version='1.0' encoding='utf-8'?> <manifest android:hardwareAccelerated="true" android:versionCode="16" android:versionName="0.0.1" android:windowSoftInputMode="adjustPan" package="de.wiedemann.mobile" xmlns:android="http://schemas.android.com/apk/res/android"> <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" /> <uses-permission android:name="android.permission.INTERNET" /> <application android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:launchMode="singleTop" android:name="wiedemann.app.WIEDEMANN" android:theme="@android:style/Theme.Black.NoTitleBar"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:clearTaskOnLaunch="true" android:configChanges="orientation|keyboardHidden" android:exported="false" android:name="com.google.zxing.client.android.CaptureActivity" android:screenOrientation="landscape" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:windowSoftInputMode="stateAlwaysHidden"> <intent-filter> <action android:name="com.google.zxing.client.android.SCAN" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> <activity android:label="@string/share_name" android:name="com.google.zxing.client.android.encode.EncodeActivity"> <intent-filter> <action android:name="com.phonegap.plugins.barcodescanner.ENCODE" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> <activity android:label="@string/share_name" android:name="com.google.zxing.client.android.HelpActivity"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="19" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.FLASHLIGHT" /> <uses-feature android:name="android.hardware.camera" android:required="false" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> </manifest>

Answer 2

将WIEDEMANN.java的包路径（在Eclipse中，而不是在Manifest中）重命名为wiedemann.app＆gt; de.wiedemann.mobile（正如您在gen文件夹中看到的正确的包名称）。请将符号更改为小写。使用 F2 热键重命名;）
