    <p>First, ensure that you have added</p> <pre><code>&lt;uses-permission android:name="android.permission.READ_CONTACTS"/&gt; </code></pre> <p>to your AndroidManifest.xml file, then you can loop through your phone contacts like this: </p> <pre><code>Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); while (cursor.moveToNext()) { String contactId = cursor.getString(cursor.getColumnIndex( ContactsContract.Contacts._ID)); String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); if (Boolean.parseBoolean(hasPhone)) { // You know it has a number so now query it like this Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); while (phones.moveToNext()) { String phoneNumber = phones.getString(phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER)); } phones.close(); } Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null); while (emails.moveToNext()) { // This would allow you get several email addresses String emailAddress = emails.getString( emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); } emails.close(); } cursor.close(); </code></pre> <p>Additionally, you can loop through your contacts and simply get the name and phone number like this:</p> <pre><code>Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); while(people.moveToNext()) { int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME); String contact = people.getString(nameFieldColumnIndex); int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER); String number = people.getString(numberFieldColumnIndex); } people.close(); </code></pre> <p>Furthermore, if you need to get things like notes from a contact then you will need to use a different URI, like the following (feel free to use this method):</p> <pre><code>private String getNote(long contactId) { String note = null; String[] columns = new String[] { ContactsContract.CommonDataKinds.Note.NOTE }; String where = ContactsContract.Data.RAW_CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?"; String[] whereParameters = new String[]{Long.toString(contactId), ContactsContract.CommonDataKinds.Note.CONTENT_ITEM_TYPE}; Cursor contacts = getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, where, whereParameters, null); if (contacts.moveToFirst()) { rv = contacts.getString(0); } contacts.close(); return note; } </code></pre> <p>Notice this time I used not only the contact id but the mime type for the query.</p>

    1. COThat was perfect Javier, thanks for this, I had to adapt it a bit for my purpose (check if a contact is in to avoid adding again). Here is my code if you want to add it to your post : String[] contactNameColumn = { ContactsContract.Contacts.DISPLAY_NAME }; Cursor checkContactInDatabase = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, contactNameColumn, ContactsContract.Contacts.DISPLAY_NAME + "=" + "'" + name + "'", null, null); if (checkContactInDatabase.moveToFirst()) { int nameFieldColumnIndex = checkContactInDatabase.getColumnIndex(PhoneLookup.DISPLAY_NAME);

    2. COString contact = checkContactInDatabase.getString(nameFieldColumnIndex); Toast.makeText(Contact.this, contact + " " + getString(R.string.alreadySaved), Toast.LENGTH_SHORT).show(); } else { Intent i = new Intent(Intent.ACTION_INSERT_OR_EDIT); i.setType(Contacts.CONTENT_ITEM_TYPE); i.putExtra(Insert.NAME, name); i.putExtra(Insert.PHONE, phone); i.putExtra(Insert.COMPANY, companie); i.putExtra(Insert.POSTAL, adresse); startActivity(i); } checkContactInDatabase.close();

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
