israelbenh :
I want to make a WhatsApp call to a specific user. I tried this and it doesn't work:
Uri uri = Uri.parse("callto:" + phoneNUmber);
Intent i = new Intent(Intent.ACTION_CALL, uri);
i.setPackage("com.whatsapp");
startActivity(i);
I know how to create a WhatsApp message, the code is similar and it works:
Uri uri = Uri.parse("smsto:" + phoneNUmber);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.setPackage("com.whatsapp");
startActivity(i);
Adnan Khan :
Simple solution is, Query ContactContract.Data for the _id and MIME type.
ContentResolver resolver = context.getContentResolver();
cursor = resolver.query(
ContactsContract.Data.CONTENT_URI,
null, null, null,
ContactsContract.Contacts.DISPLAY_NAME);
//Now read data from cursor like
while (cursor.moveToNext()) {
long _id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
Log.d("Data", _id+ " "+ displayName + " " + mimeType );
}
The output will be like the following
12561 Snow vnd.android.cursor.item/vnd.com.whatsapp.profile
12562 Snow vnd.android.cursor.item/vnd.com.whatsapp.voip.call
Now save in DB or somewhere else only those _Ids whose MIME type is vnd.android.cursor.item/vnd.com.whatsapp.voip.call
And then you initiate Whatsapp call with those contacts like this way
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
// the _ids you save goes here at the end of /data/12562
intent.setDataAndType(Uri.parse("content://com.android.contacts/data/_id"),
"vnd.android.cursor.item/vnd.com.whatsapp.voip.call");
intent.setPackage("com.whatsapp");
startActivity(intent);
