What it changes

Section titled “What it changes”

Android: in AndroidManifest.xml, it adds one <package android:name="…" /> per entry inside the first <queries> block, creating the block if needed. Names are trimmed and de-duplicated, and packages already listed aren’t added twice.

<queries>
  <package android:name="com.whatsapp" />
</queries>

iOS: in Info.plist, it merges the schemes into LSApplicationQueriesSchemes, keeping anything already there. Schemes are trimmed, ://… or a trailing : is removed, and duplicates are dropped.

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>whatsapp</string>
</array>

Errors during prebuild

Section titled “Errors during prebuild”
  • Invalid iOS URL scheme: <value>: an ios entry is empty or not a valid scheme after trimming.
  • AndroidManifest.xml is invalid or missing!: prebuild couldn’t read the Android manifest.
