@Kristopher - Do you have any resource files? If so, you might have an error due to the resource body tag not being empty. Check [this](https://stackoverflow.com/questions/52076491/android-inner-element-must-either-be-a-resource-reference-or-empty) solution. — tomerpacific, Dec 09 '18 at 06:48

Should be:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item name="timebar" type="id"/>
    <item name="textClock" type="id"/>
</resources>

the ref is here.

On your Resource File remove the closing tag plus the Body i.e Remove "tv_deviceName"

  <item type="id" name="button_ok">tv_deviceName</item>

Id should be like this as below

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item type="id" name="button_ok" />
    <item type="id" name="dialog_exit" />
</resources>

Then, this layout snippet uses the "button_ok" ID for a Button widget:

<Button android:id="@id/button_ok"
    .... />

Notice that the android:id value does not include the plus sign in the ID reference, because the ID already exists, as defined in the ids.xml example above. (When you specify an ID to an XML resource using the plus sign—in the format android:id="@+id/name"—it means that the "name" ID does not exist and should be created.)

As another example, the following code snippet uses the "dialog_exit" ID as a unique identifier for a dialog:

showDialog(R.id.dialog_exit);
