I use the Realm.io library to transfer data to the MPAndroidChart graph. I add to the database as follows:

protected void writeToDB() { Realm realm = Realm.getInstance(this); realm.beginTransaction(); float f = 24; int i = 5; String s ="1100";; RealmDemoData d = new RealmDemoData(f, i, s); realm.copyToRealm(d); realm.commitTransaction(); }

Everything is added, everything is fine, trying to get the data:

 RealmResults<RealmDemoData> result = mRealm.allObjects(RealmDemoData.class); RealmLineDataSet<RealmDemoData> set = new RealmLineDataSet<RealmDemoData>(result, "value", "xIndex");

And errors immediately take off, and only when I use RealmLineDataSet .
The error itself:

  • RealmDemoData your RealmDemoData class RealmDemoData RealmObject and RealmLineDataSet class RealmLineDataSet exist? You get the error that the class or method you are trying to call does not exist. - pavlofff

Yes, that's right, the error was in the RealmLineDataSet class, the plug-in jar did not correctly indicate the placement of RealmDinamicObject, plugged in as a module and the problem was solved, thanks!
