To get the number of contacts on your device, first make sure that you have set this permission in your android manifest.

<uses-permission android:name="android.permission.READ_CONTACTS" />

Then you can use this to retrieve the number of contacts:

ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
int numberOfContacts = cur.getCount();
Toast.makeText(this, String.valueOf(numberOfContacts), Toast.LENGTH_SHORT).show();
