Please help me resolve the following exception?

Question

When I click the button, I want to show the contact list and get the contact number selected by the user. here is my code:

public class MainActivity extends Activity { int level; final int PICK_CONTACT =1; private TextView textView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textView = new TextView(this); textView.setWidth(100); textView.setHeight(100); @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } public void onClick(View v) { @SuppressWarnings("deprecation") //Contracts class is deprecated , please tell any other alternative if possible. Intent intent= new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI); startActivityForResult(intent, PICK_CONTACT); } @Override public void onActivityResult(int reqCode, int resultCode, Intent data) { super.onActivityResult(reqCode, resultCode, data); switch (reqCode) { case (PICK_CONTACT) : if (resultCode == Activity.RESULT_OK) { Uri contactData = data.getData(); Cursor c = managedQuery(contactData, null, null, null, null); if (c.moveToFirst()) { //here am retrieving name , please tell how to retrieve number as well String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); textView.setText(name); // TODO Fetch other Contact details as you want to use } } break; } } } 

Added permission in manifest file: android.permission.READ_CONTACTS

I don’t know if this is really required or not.

Also tell me if I can ant extract several contacts selected by the user from the contact list.

here is my magazine:

Answer 1

in your onclick button you need to add aim.setType (Phone.CONTENT_TYPE); it is not in your code, please use the following code.

  Intent intent= new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI); intent.setType(Phone.CONTENT_TYPE); startActivityForResult(intent, PICK_CONTACT);
