Basic Code for Twitter oAuth for Android works with any version of Android I have tested it against – will crash if no Internet access but adding a check for this is relevantly simple (wanted to keep the code just about the oAuth process – the core idea and code comes from this blogpost

Constants Code you need to enter your own Twitter Developer keys here
package me.crowleydavid.android.basicoauth;
public class Constants {
public static final String CONSUMER_KEY = "************";
public static final String CONSUMER_SECRET= "**************";
TwitterWebviewActivity Code
package me.crowleydavid.android.basicoauth;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class TwitterWebviewActivity extends Activity {
private Intent mIntent;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.twitter_webview);
mIntent = getIntent();
String url = (String)mIntent.getExtras().get("URL");
WebView webView = (WebView) findViewById(R.id.webview);
webView.setWebViewClient( new WebViewClient()
{
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
if( url.contains(getResources().getString( R.string.twitter_callback )))
{
Uri uri = Uri.parse( url );
String oauthVerifier = uri.getQueryParameter( "oauth_verifier" );
mIntent.putExtra( "oauth_verifier", oauthVerifier );
setResult( RESULT_OK, mIntent );
finish();
return true;
}
return false;
}
});
webView.loadUrl(url);
}
}
}
CheckNetAccess Code

Android Manifest needs these permissions
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
