i use contact picker code from another stackoverflow question:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == RESULT_PICK_CONTACT) {
Cursor cursor;
try {
String phoneNo = "";
String name = "";
Log.i("intent",data.getData().toString());
Uri uri = data.getData();
cursor = this.getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int phoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
phoneNo = cursor.getString(phoneIndex);
int nameColumnIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
name = cursor.getString(nameColumnIndex);
cursor.close();
Log.i("phone", phoneNo);
Log.i("name", name);
contactPicked(name,phoneNo);
} catch (Exception e) {
e.printStackTrace();
}
}
} else {
Log.e("MainActivity", "Failed to pick contact");
}
}
private void pickContact(){
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT);
}
also i noticed that on android 11 content uri slightly changed:
android 11: intent: content://com.android.contacts/data/3
android 10: intent: content://com.android.contacts/data/1
I solved problem: the reason was that in android 11 i had to manually ask for contact read permissiom, while in android 10 that code worked fine.
Solution: manually ask for contact read permission
