fix: APPLICATION_ID meta-data read as Integer instead of String (fixes #13)

[juliosuas]

Problem

In AndroidManifest.xml, the APPLICATION_ID meta-data is defined as:

<meta-data
    android:name="com.meta.wearable.mwdat.APPLICATION_ID"
    android:value="0"
/>

Android's Bundle interprets "0" as a java.lang.Integer, not a String. The Meta Wearables DAT SDK expects a String value via Bundle.getString(), which returns null for non-String types. This breaks the deep link construction for the registration flow, showing "Error opening link" on the Meta Stella app.

Logcat evidence:

W/Bundle: Key com.meta.wearable.mwdat.APPLICATION_ID expected String but value was a java.lang.Integer.

Fix

Reference the value via a string resource instead of an inline literal:

strings.xml:

<string name="mwdat_application_id" translatable="false">0</string>

AndroidManifest.xml:

android:value="@string/mwdat_application_id"

This forces Android to treat the value as a String.

Files Changed

• app/src/main/AndroidManifest.xml
• app/src/main/res/values/strings.xml

Test plan

• "Connect my glasses" opens Meta Stella correctly (no error dialog)
• Logcat no longer shows the Integer type mismatch warning
