Android get phone contacts

I'll demonstrate Android get phone contacts example. First create a new Android project in Eclipse . Then in your created xml layout just define the following things:

Just add the following codes to your Activity class:

public class ContactFetchActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button contactButton = (Button)findViewById(R.id.button1);
        
  contactButton.setOnClickListener(l);
    }
    
    OnClickListener l = new OnClickListener(){

  @Override
  public void onClick(View arg0) {
   try{
    Uri contactData = ContactsContract.Contacts.CONTENT_URI;
    Cursor contactsCursor = managedQuery(contactData,null, null, null, null);
    Log.i("The first one ", ""+ contactsCursor.getCount());
    while (contactsCursor.moveToNext()) {
     String id = contactsCursor.getString(contactsCursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
     String name = contactsCursor.getString(contactsCursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
     String hasPhoneNumber = contactsCursor.getString(contactsCursor.getColumnIndexOrThrow(ContactsContract.Contacts.HAS_PHONE_NUMBER));
     Toast.makeText(ContactFetchActivity.this, Integer.parseInt(hasPhoneNumber) + "", 11).show();
     if (Integer.parseInt(hasPhoneNumber) > 0) {
      Uri myPhoneUri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, id);
      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null);
      String phoneNumber = null;
      while (phones.moveToNext()) {
       phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
       Toast.makeText(ContactFetchActivity.this, phoneNumber , 20).show();
      }
      Toast.makeText(ContactFetchActivity.this, id + "-----" + name , 20).show();
     }
     
    }
   }catch(Exception ex){
    Toast.makeText(ContactFetchActivity.this, "Problem because " + ex.getMessage(), 10).show();
   }
   //Uri myPerson = ContentUris.withAppendedId(contentUri, id)
  }
    };
}

Just fix your imports. And then finally on your AndroidManifest.xml file add the line:
