for science project I'm direct messaging twitter with twitter4j lib and android 2.1 but app immediately crashes

I'm a complete beginner in java but I need to make this application to send commands over twitter. I'm using the twitter4J library and android 2.1. I finally have my code with no errors but when the app starts in the emulator, it immediately crashes. Has anyone done this before?

CODE(main file):

package edu.shs.SHSSRP;

import twitter4j.Status;
import twitter4j.Twitter;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import edu.shs.SHSSRP.TwitterTest;
import android.os.Bundle;
import android.webkit.WebView;
import android.widget.Button;

public class SHSSRP extends Activity {
     /** Called when the activity is first created. */  
WebView webview;
Button Forward;
Button Backward;
Button Left;
Button Right;
TwitterTest TwitTest;
public void onCreate(Bundle savedInstanceState) {


 Twitter twitter = new TwitterFactory().getInstance("SHSSRP","123ABC1234");
 try {
    Status status = twitter.updateStatus("HELLO WORLD!");
} catch (TwitterException e) {
    // TODO Auto-generated catch block
/*        Forward = (Button) findViewById(;
    Backward = (Button) findViewById(;
    Left = (Button) findViewById(;
    Right = (Button) findViewById(;
    webview = (WebView) findViewById(;


package edu.shs.SHSSRP;

import twitter4j.DirectMessage;
import twitter4j.ResponseList;
import twitter4j.Twitter;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import twitter4j.*;

public class TwitterTest extends Activity 
 public void runTest() 
       // The factory instance is re-usable and thread safe. 
       Twitter twitter = new TwitterFactory().getInstance("SenderID","SenderPass");
       try {
        twitter.sendDirectMessage("ReceiverID", "HelloWorld");
    } catch (TwitterException e) {

CODE(manifest) simply add the uses permission for interet



        android:layout_height="fill_parent"  />

        android:text="@string/Forward" />

        android:text="@string/Left" />

        android:text="@string/Right" />

        android:text="@string/Backward" />

thank you in advance,

Answer 1

In your AndroidManifest.xml file you need to specify that your application will connect to the internet.

Paste this just above the <application> node:

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

Answer 2

As the other folk have indicated, posting the stack trace would be a big help.

That being said, you might also consider switching to JTwitter. I know from first-hand experience that it works on Android, though I tend to remove the duplicate org.json classes that JTwitter has in its published JAR.
