I have an application with a LoginActivity
, that when the user login correctly, I register to receive messages. And the LoginActivity
jumps to MainActivity
.
The arriving messages are supposed to be stored in database (Realm), to recover from a Realm instance in Main.
But when the message arrives It crash realm launching this errror:
Exception in packet listener
java.lang.IllegalStateException: Realm access from incorrect thread. Realm objects can only be accessed on the thread they were created.

I'm a bit lost on how Realm works, and I don't know how to make realm accessible across the application without a crash and keep storing this received messages from LoginActivity
. Some help, or approaches to achieving this?
LoginActivity.java:
public class LoginActivity extends AppCompatActivity implements ConnectionConnectResponse {
.....
protected void onCreate(Bundle savedInstanceState) {
//Realm Init config:
Realm.init(this);
RealmConfiguration realmConfiguration = new RealmConfiguration.Builder().build();
Realm.deleteRealm(realmConfiguration); // Clean slate
Realm.setDefaultConfiguration(realmConfiguration); // Make this Realm the default
@Override
public void newMessageReceived(final ChatMessage message) {
Logger.d("NEWMESSAGERECEIVED :" + message);
realm.executeTransactionAsync(new Realm.Transaction() {
@Override
public void execute(Realm realm) {
Message receivedMessage = realm.createObject(Message.class, message.id);
receivedMessage.setBodyMessage(message.message);
receivedMessage.setFrom(message.from);
receivedMessage.setTo(message.to);
receivedMessage.setDelivered(false);
receivedMessage.setMine(false);
receivedMessage.setDate(Calendar.getInstance().getTime());
}
});
//Logger.d("NEWMESSRE: LAST MESSAGE:" + realm.where(Message.class).equalTo("chatID", message.id));
}
@Override
protected void onStart() {
super.onStart();
realm = Realm.getDefaultInstance();
}
@Override
protected void onStop() {
super.onStop();
realm.close();
}
