+The filesystem used by Android emulators is not directly accessible 
+from the machine running Realm Studio. You must download the file
+from the emulator before you can access it.
+
+First, find the path of the file on the emulator:
+
+.. code-block:: java
+
+   // Run this on the device to find the path on the emulator
+   Realm realm = Realm.getDefaultInstance();
+   Log.i("Realm", realm.getPath());
+
+Then, download the file using ADB. You can do this while the app 
+is running.
+
+.. code-block:: java
+
+   > adb pull <path>
+
+You can also upload the modified file again using ADB, but only 
+when the app isn't running. Uploading a modified file while the 
+app is running can corrupt the file.
+
+.. code-block:: java
+
+   > adb push <file> <path>

+To export updated class definitions:
+
+- Go to :guilabel:`File` > :guilabel:`Save model definitions`, and select
+  your preferred language. Supported languages include: Swift, JavaScript,
+  TypeScript, Java, Kotlin, and C#. 
+- Specify a name and destination for your new class definitions. Press
+  the :guilabel:`Save` button.
+
+If your destination directory does not already exist, Realm Studio creates 
+it. Inside, you'll find a file that contains a complete list of classes 
+and properties, including new additions.
