这里是我的应用程序的应用类....

package com.adamwhiles.tw33tz.application; 

import oauth.signpost.OAuthProvider; 
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer; 
import twitter4j.Twitter; 
import android.app.Application; 

public class Tw33tzApplication extends Application { 

    private Twitter twitter; 

    /** @return the twitter */ 
    public Twitter getTwitter() { 
     return twitter; 
    } 

    /** @param twitter 
    *   the twitter to set */ 
    public void setTwitter(Twitter twitter) { 
     this.twitter = twitter; 
    } 

    private OAuthProvider provider; 
    private CommonsHttpOAuthConsumer consumer; 

    /** @param provider 
    *   the provider to set */ 
    public void setProvider(OAuthProvider provider) { 
     this.provider = provider; 
    } 

    /** @return the provider */ 
    public OAuthProvider getProvider() { 
     return provider; 
    } 

    /** @param consumer 
    *   the consumer to set */ 
    public void setConsumer(CommonsHttpOAuthConsumer consumer) { 
     this.consumer = consumer; 
    } 

    /** @return the consumer */ 
    public CommonsHttpOAuthConsumer getConsumer() { 
     return consumer; 
    } 
} 

这里是清单我的应用程序：

     package="com.adamwhiles.tw33tz"

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

     </activity> 
     <activity android:name=".Tw33tzActivity"></activity> 
    </application> 
</manifest> 

希望这有助于....

它不能找到一个类它一直引相信它应该能够。我怀疑你没有在清单和代码中始终如一地拼写：

未解决的类com.adamwhiles.tw33tz。 appliaction .Tw33tzApplication

来自清单

android:name=".appliaction.Tw33tzApplication" 

VS源提供

package com.adamwhiles.tw33tz.application;
