Question

String[] ids = new String[]{"1","2","3","4"};
Cursor emailCur = getContentResolver().query( 
                ContactsContract.CommonDataKinds.Email.CONTENT_URI, 
                null,
                ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
                ids, null);

I think it should be problem of the included parameter.

I tried to put there

String[] ids = new String[]{"(1,2,3,4)"};
// or
String[] ids = new String[]{"('1','2','3','4')"};

and tried that with changing + " = ?", to + " IN ?",, didn’t worked at all…

I’d like to select all rows with ID in ARRAY, How am I supposed to do that?

Answer 1

I suspect that what you are trying to do isn’t easily achievable.

Having said that I would tackle the problem by using your original code but changing the where clause to be:

ContactsContract.CommonDataKinds.Email.CONTACT_ID + " IN(?,?,?,?)"

You will have to add a ? mark for each id value you wish to specify in the IN clause using a for-loop
