Access phone book (contacts) using Kivy

Question

I am developing a mobile app using Kivy. I would like to access the phone book (contact list). Is there an easy way like accessing the mobile sensors using plyer.

Note: I am not an android expert.

Answer 1

First thing you'll need permission, add the READ_CONTACTS premission to your buildozer spec.

Now, you should use pyjnius to use the Java SDK like this:

-this is not tested-

  PythonActivity=autoclass("org.renpy.android.PythonActivity")
  ContactsContract=autoclass("android.provider.ContactsContract")

  cr = PythonActivity.mActivity.getContentResolver()
  null = None # this will help to convert java examples into python ones :)
  cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
                 null, null, null, null)
  if (cur.getCount() > 0):
      while (cur.moveToNext()):
          id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
          name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)) #I think this is not DISPLAY_NAME in all versions ...
          print("->", id, name)

        #you can further query contact by its id

the logic is taken from this answer: android get all contacts

There is also this pull request for plyer that you might want to test: https://github.com/kivy/plyer/pull/125/

Answer 2

I needed this and searched a lot but couldn't find solution which is full code and understandable. I hope these explanations will be enough to figure out.

Accessing correctly PythonActivity:

PythonActivity = autoclass("org.kivy.android.PythonActivity")

Accessing Contacts Java Class:

Contacts = autoclass("android.provider.ContactsContract$Contacts")

Accessing ContactsContract.CommonDataKinds.Phone Java Class (same):

Kinds = autoclass("android.provider.ContactsContract$CommonDataKinds$Phone")

Creating getContentResolver():

cr = PythonActivity.mActivity.getContentResolver()

Now we need to create 2 query. In first, we are going to find ID and need to use it in second query to find equal NUMBER. Also need to check is contact has phone number? too. After that we can loop second query to find number:

name_number_dict= {}   # Name:Number  # Change as you wish..
    while (que1.moveToNext()):  #Query 1 Loop
        if que1.getString(que1.getColumnIndex(Contacts.HAS_PHONE_NUMBER)):  #If has number
            que2 = cr.query(Kinds.CONTENT_URI, None, Kinds.CONTACT_ID + " = " + que1.getString(que1.getColumnIndex(CONTACTS_ID)), None, None)  #Query 2 Loop
            while (que2.moveToNext()):
                name_number_dict[que1.getString(que1.getColumnIndex(Contacts.DISPLAY_NAME))] = que2.getString(que2.getColumnIndex(Kinds.NUMBER)  # Get datas and put in dic.

• If you need to check all ColumnNames of query, use query1.getColumnNames() >> Referance

• If you need to find count : query1.getCount() will be useful.
