Jetpack Compose Contact Picker-CodePudding

So... Yesterday my code was working just fine, but today, I don't know what happend it stoped working. The cursor is null and returns both "". I don't know what to do.

Is the cursor even working?

@SuppressLint("Range", "Recycle")
@Composable
fun ContactPickerTwinTurbo(
    done: (String, String) -> Unit
) {
    val context = LocalContext.current
    val launcher = rememberLauncherForActivityResult(
        contract = ActivityResultContracts.PickContact(),
        onResult = {
            val contentResolver: ContentResolver = context.contentResolver
            var name = ""
            var number = ""
            val cursor: Cursor? = contentResolver.query(it!!, null, null, null, null)
            if (cursor != null) {
                if (cursor.moveToFirst()) {
                    name =
                        cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME))
                    Log.d("Name", name)
                    val id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID))
                    val phones: Cursor? = contentResolver.query(
                        Phone.CONTENT_URI, null,
                        Phone.CONTACT_ID   " = "   id, null, null
                    )
                    if (phones != null) {
                        while (phones.moveToNext()) {
                            number = phones.getString(phones.getColumnIndex(Phone.NUMBER))
                            Log.d("Number", number)
                        }
                        phones.close()
                    }
                }
            }
            done(name, number)
        }
    )
    Button(
        onClick = {
            launcher.launch()
        },
        modifier = Modifier
            .fillMaxWidth()
            .padding(10.dp)
    ) {
        Text(text = "Pick Contact")
    }
}

How does the cursor works? Do I have to wait? am I supposed to ask permission to access the contacts?

CodePudding user response：

Apparently Yes you need to ask for permission in runtime to get access the contact. For References check this link [check link][1]https://www.geeksforgeeks.org/contact-picker-in-android-using-jetpack-compose/
