twitter integration on android app

I would like to integrate Twitter into my Android开发者_开发技巧 application so that I can post messages to Twitter.

This is how I do it

First i made a Dialog for the webview Twitter_Dialog.java

public class Twitter_Dialog extends Dialog
{

static final int                      BLUE                  = 0xFF6D84B4;
static final float[]                  DIMENSIONS_DIFF_LANDSCAPE =
                                                                { 20, 60 };
static final float[]                  DIMENSIONS_DIFF_PORTRAIT  =
                                                                { 40, 60 };
static final FrameLayout.LayoutParams   FILL                    = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
static final int                      MARGIN                    = 4;
static final int                      PADDING                   = 2;
static final String                   DISPLAY_STRING            = "touch";

private String                        mUrl;
private ProgressDialog                mSpinner;
private WebView                       mWebView;
private LinearLayout                  mContent;
private TextView                      mTitle;

public Twitter_Dialog(Context context, String url)
{
    super(context);
    mUrl = url;
}

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    mSpinner = new ProgressDialog(getContext());
    mSpinner.requestWindowFeature(Window.FEATURE_NO_TITLE);
    mSpinner.setMessage("Loading...");

    mContent = new LinearLayout(getContext());
    mContent.setOrientation(LinearLayout.VERTICAL);
    setUpTitle();
    setUpWebView();
    Display display = getWindow().getWindowManager().getDefaultDisplay();
    final float scale = getContext().getResources().getDisplayMetrics().density;
    int orientation = getContext().getResources().getConfiguration().orientation;
    float[] dimensions = (orientation == Configuration.ORIENTATION_LANDSCAPE) ? DIMENSIONS_DIFF_LANDSCAPE : DIMENSIONS_DIFF_PORTRAIT;
    addContentView(mContent, new LinearLayout.LayoutParams(display.getWidth() - ((int) (dimensions[0] * scale + 0.5f)), display.getHeight() - ((int) (dimensions[1] * scale + 0.5f))));
}

private void setUpTitle()
{
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    Drawable icon = getContext().getResources().getDrawable(R.drawable.twitter_icon);
    mTitle = new TextView(getContext());
    mTitle.setText("Website");
    mTitle.setTextColor(Color.WHITE);
    mTitle.setTypeface(Typeface.DEFAULT_BOLD);
    mTitle.setBackgroundColor(BLUE);
    mTitle.setPadding(MARGIN + PADDING, MARGIN, MARGIN, MARGIN);
    mTitle.setCompoundDrawablePadding(MARGIN + PADDING);
    mTitle.setCompoundDrawablesWithIntrinsicBounds(icon, null, null, null);
    mContent.addView(mTitle);
}

private void setUpWebView()
{
    mWebView = new WebView(getContext());
    mWebView.setVerticalScrollBarEnabled(false);
    mWebView.setHorizontalScrollBarEnabled(false);
    mWebView.setWebViewClient(new Twitter_Dialog.DialogWebViewClient());
    mWebView.getSettings().setJavaScriptEnabled(true);
    System.out.println(" mURL = "+mUrl);

    mWebView.loadUrl(mUrl);
    mWebView.setLayoutParams(FILL);
    mContent.addView(mWebView);
}

private class DialogWebViewClient extends WebViewClient
{

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url)
    {
        view.loadUrl(url);
        return true;
    }
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
    {
        super.onReceivedError(view, errorCode, description, failingUrl);
        Twitter_Dialog.this.dismiss();
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon)
    {
        super.onPageStarted(view, url, favicon);
        mSpinner.show();
    }

    @Override
    public void onPageFinished(WebView view, String url)
    {
        super.onPageFinished(view, url);
        String title = mWebView.getTitle();
        if (title != null && title.length() > 0){
            mTitle.setText(title);
            if(title.equals("Twitter")){
                //This will close the Dialog after tweeting
                Twitter_Dialog.this.dismiss();

            }
        }
        mSpinner.dismiss();
    }

}
}

//And then into your Main.java

public class Main extends Activity {
 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
            new Twitter_Dialog(Main.this,"http://twitter.com/?status="+Uri.encode("Twitter Post")).show();
    }

}

In addition to d.'s solid choices, you could:

• Use ACTION_SEND Intents with createChooser(), and if the user has a Twitter application installed (Twidroid) they can use it to update their status
• Use an existing Twitter Java API, like JTwitter

Everything you need to know about communicating with Twitter is here.

For sending HTTP requests from your application, check out this guide.

You can use Twitter Helper for integrating Twitter into your Android app. Its very simple.

Try with this simple client TwitterEasyClient

Just add permissions in your manifest

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

And use it in this way:

    //setup
    TwitterDialogFragment twitterDialog = new TwitterDialogFragment.Builder("message","url.com") //
    .callbackUrl("http://www.website.com") //
    .consumerKey("XXXXXXXXXXXXXXXXXXXXXX") //
    .consumerSecret("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX") //
    .urlOAuth("oauth_verifier") //
    .build();

    //show the dialog
    twitterDialog.show(getSupportFragmentManager(), TwitterDialogFragment.class.getSimpleName());

Always go for the latest technologies as twitter integration can be done easily using Twitter4j, also the APIs provided by twitter does change from time to time. Twiter sdk would a good option. U can find the details for it here for twitter4j.

For some people who want to use twitter4j and DialogFragment also support orientation changing check out my gist https://gist.github.com/zeroarst/10071064adcf171277f9
