의도를 통해지도 작업을 시작할 때 NoClassDefFoundError 받기

Question

Android에서지도보기 구현을 처음 사용했습니다. 나는 google지도를 포함 할 새로운 활동을 (단추 누르기에) 발사하는 것을 시도하고있다. 나는 http://developer.android.com/guide/tutorials/views/hello-mapview.html에 언급 된 모든 것을하고있는 것처럼 보입니다. 그러나 나는 다음과 같은 오류를 받고 있어요 : -

이는 방법하려면 showlocator의 모습입니다 : -

public void showLocator(View view) { 
    Intent i = new Intent(SelfDefActivity.this, LocationActivity.class); 
    final int result=1; 
    startActivityForResult(i, result); 
    finish(); 
} 

이 내 매니페스트 모습입니다 같은 : -

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="org.sam" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk android:minSdkVersion="10" /> 

    <uses-permission android:name="android.permission.INTERNET" /> 

    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@android:style/Theme.NoTitleBar" > 
     <activity 
      android:name=".SelfDefActivity" 
      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=".LocationActivity" 
      android:label="@string/location_activity" > 
      <uses-library android:name="com.google.android.maps" /> 
     </activity> 
    </application> 

</manifest> 

아무도 내가 잘못 가고 있다고 말할 수 있습니까?

Answer 1

는

활동 이름으로 android:name="your package name.LocationActivity"

같은 매니페스트 파일에서의 활동에 대한 전체 경로를 추가하여이 권한을 추가해야 위치를 확인하는 것이 좋습니다 그 또한

아래처럼 보일 것 매니페스트

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="org.sam" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk android:minSdkVersion="10" /> 

    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@android:style/Theme.NoTitleBar" > 
     <activity

      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=".LocationActivity" 
      android:label="@string/location_activity" > 
     </activity> 
     <uses-library android:name="com.google.android.maps" /> 
    </application> 

</manifest>
