내 매니페스트

같은 오류를 얻고있다 내 응용 프로그램을 실행하려고 해요 때 이제 SDK를 업데이트하고 잘 어제하지만 오늘은 일하고 있었다

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.lpp.towndefence" 
    android:versionCode="1" 
    android:versionName="1.0" > 
    <uses-sdk android:minSdkVersion="7"/> 
    <uses-permission android:name="android.permission.WAKE_LOCK"/> 
    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" > 
     <activity 
      android:label="@string/app_name" 
      android:name=".MainMenuActivity" > 
      <intent-filter > 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
     <activity 
      android:name=".TownDefenseActivity"> 
     </activity> 
    </application> 

</manifest> 

프로젝트, 고정 프로젝트 속성을 정리했지만 도움이되지 않았습니다.

Answer 1

@Barak처럼 : jar 파일은 libs 디렉토리에 있습니다. 하지만 "프로젝트 속성"-> "자바 빌드 경로"-> "주문 및 내보내기"에서도 라이브러리를 확인해야합니다.
