I have been getting this error every since importing my existing project into a new workspace.

下面是我的清单和其他一切是正确的包在我的源文件夹。

Here is my manifest and everything else is in the correct package in my source folder.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.fttech.hh"
android:versionCode="1"
android:versionName="1.0" >
 <uses-sdk android:minSdkVersion="4" />
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

   <application android:icon="@drawable/ic_launcher" android:label="@string/app_name">
    <activity android:name=".MenuActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

    </activity>
    <activity android:name=".Arcade_MainGame"></activity>
    <activity android:name=".MainGame"></activity>
    <activity android:name=".MyPreferenceClass"></activity>
    <activity android:name=".unlockable"></activity>


</application>
</manifest>

你们看到什么即时通讯做错了什么？

Anyone see what im doing wrong?

推荐答案

确定，这是在清单中。是否MenuActivity有权包？是MenuActivity present的apk文件？

OK, it's in the manifest. Does MenuActivity have the right package? Is MenuActivity present in the .apk?
