I've created an application which shares to facebook, twitter etc. But I want to perform different functions dependent on who the user is sharing to, for instance if the user is sharing to Facebook do one thing but if the user shares to twitter do another.

How do I do this?

My code so far is below:

private void ShareSub() { Intent i = new Intent(Intent.ACTION_SEND); i.setType("text/plain"); i.putExtra( Intent.EXTRA_TEXT, "You've just shared " + "Awesome"); startActivity(i); }

So far in Android I know how to wall post to the user's wall via the web but I'd like, the app to detect whether the user has the facebook application installed and if so post via that. Does anyone know how to do this?


My code so far is below:


public class MainActivity extends Activity { private static String FACEBOOK_APP_ID = "276023232498070"; private static final String[] PERMISSIONS = new String[] { "publish_stream","email","user_birthday","user_location" }; private Facebook facebook; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); facebook = new Facebook(FACEBOOK_APP_ID); Bundle parameters = new Bundle(); parameters.putString("app_id", "276023232498070"); parameters.putString("link", "https://play.google.com/store/apps/details?id=myappistasty"); parameters.putString("name", "This is the name of the link set in app."); parameters.putString("caption", "This is Text that is specified in bt the aoo"); parameters.putString("picture", "http://i.dailymail.co.uk/i/pix/2012/11/15/article-0-1609D0FF000005DC-373_964x641.jpg"); // Posting my message, maybe here i could add paramterers like icon and a link etc..? facebook.dialog(MainActivity.this, "feed", parameters,new PostDialogListener()); } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); facebook.authorizeCallback(requestCode, resultCode, data); Toast.makeText(getApplicationContext(), "Hello", Toast.LENGTH_LONG).show(); } public abstract class BaseDialogListener implements DialogListener { @Override public void onFacebookError(FacebookError e) { e.printStackTrace(); } @Override public void onError(DialogError e) { e.printStackTrace(); } @Override public void onCancel() { } } public class PostDialogListener extends BaseDialogListener { @Override public void onComplete(Bundle values) { final String postId = values.getString("post_id"); if (postId != null) { Log.e("","Message posted on the wall."); MainActivity.this.finish(); } else { Log.e("","No message posted on the wall."); MainActivity.this.finish(); } } } }

Irina Goble wrote:Have you tried to set the shared history file to null? Something like:
myShareActionProvider.setShareHistoryFileName(null);
Your activity implements the OnShareTargetSelectedListener interface. Shouldn't you use it as a listener instead of creating an anonymous inner class.

I tried that, couldn't get it to work...

Have you had any luck??

What changes would you make to the above code?

I created a share button on the action bar and although I like the fact it allows me to share to communication components like messaging. I wanted to remove the recently shared button that appears after you've shared to for instance messaging.

I simply can't get the code for this to work.

My code and a link to my project files are below:

**MainActivity
public class MainActivity extends FragmentActivity implements OnShareTargetSelectedListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); MenuItem item_share = menu.findItem(R.id.menu_item_share); item_share.setVisible(true); ShareActionProvider myShareActionProvider = (ShareActionProvider) item_share.getActionProvider(); Intent myIntent = new Intent(); myIntent.setAction(Intent.ACTION_SEND); myIntent.putExtra(Intent.EXTRA_TEXT, "According."); myIntent.setType("text/plain"); myShareActionProvider.setShareIntent(myIntent); myShareActionProvider.setOnShareTargetSelectedListener(new OnShareTargetSelectedListener(){ @Override public boolean onShareTargetSelected(ShareActionProvider source, Intent intent) { startActivity(intent); return false; } }); return true; } @Override public boolean onShareTargetSelected(ShareActionProvider arg0, Intent arg1) { // TODO Auto-generated method stub return false; }}

Sure, I sound silly right now, but I still don't understand. Are you able to explain via an example, thanks

Stuck on how to set up a minimum and maximum date with the DatePicker, so for instance the user can't set the date pass the current date. Similarly the user won't be able select a date before 1960, so far I've been able to set up the DatePicker my code is below:

public class MainActivity extends FragmentActivity { EditText mEdit; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } public void selectDate(View view) { DialogFragment newFragment = new SelectDateFragment(); newFragment.show(getSupportFragmentManager(), "DatePicker"); } public void populateSetDate(int year, int month, int day) { mEdit = (EditText)findViewById(R.id.editText1); mEdit.setText(month+"/"+day+"/"+year); } public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { @Override public Dialog onCreateDialog(Bundle savedInstanceState) { final Calendar calendar = Calendar.getInstance(); int yy = calendar.get(Calendar.YEAR); int mm = calendar.get(Calendar.MONTH); int dd = calendar.get(Calendar.DAY_OF_MONTH); return new DatePickerDialog(getActivity(), this, yy, mm, dd); } public void onDateSet(DatePicker view, int yy, int mm, int dd) { populateSetDate(yy, mm+1, dd); } } }

More than likely. When I use it with a minimum SDK set to 11, the described error occurs



What is the fix for this? Is there another method which actually works?

I'm trying to download a web page source within android using Java, but elsewhere in my program the minimum requirement for SDK within the Android manifest needs to be set at 11 but the below code (to download source) will only work when the minimum SDK version is set to 3.

Is there any changes you would suggest I make to the below code

public void getHtml() throws ClientProtocolException, IOException { HttpClient httpClient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); HttpGet httpGet = new HttpGet("http://www.google.com"); HttpResponse response = httpClient.execute(httpGet, localContext); String result = ""; BufferedReader reader = new BufferedReader( new InputStreamReader( response.getEntity().getContent() ) ); String line = null; while ((line = reader.readLine()) != null){ result += line + "\n"; Toast.makeText(activity.this, line.toString(), Toast.LENGTH_LONG).show(); } }

Code above requires minimum SDK version 3

Rest of code requires minimum SDK version 1

When I change the minimum SDK in android manifest to 11 above code won't work

(By won't work, I mean I get the error "Unfortunately Test has stopped" and then the app closes)
