twitter integration on android app

Question

I would like to integrate Twitter into my Android application so that I can post messages to Twitter.

Answer 1

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();     }  } 

Answer 2

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
