关于Codename One生成Android TV APK清单的问题咨询

Let's break down your questions and fix the configuration issues step by step:

1. Placement of LEANBACK_LAUNCHER Intent Filter #

You're absolutely right — the LEANBACK_LAUNCHER intent filter must be nested inside the UniAlephStub activity tag to be recognized properly by Android TV systems.

Your current android.xapplication build hint adds the intent filter directly under the root <application> tag, which is invalid. Instead, use the android.xactivity hint to target the main stub activity:

android.xactivity=<intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LEANBACK_LAUNCHER" /></intent-filter>

This ensures the filter is injected into the correct <activity> block for UniAlephStub, making your app visible on Google Play for TV devices.

2. Duplicate touchscreen Feature Declaration #

You're also correct about this — Codename One automatically adds <uses-feature android:name="android.hardware.touchscreen" android:required="false" /> by default to support non-touch devices like Android TV. Manually including it in your android.xpermissions hint causes the duplicate entry in the manifest.

You can safely remove that line from your permissions hint.

Final Recommended Build Hints #

Here's the cleaned-up, correct set of build hints for Android TV compatibility:

android.xpermissions=<uses-feature android:name="android.software.leanback" android:required="false" />
android.xactivity=<intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LEANBACK_LAUNCHER" /></intent-filter>

• The leanback feature is marked as optional so your app can still run on devices without the leanback library (like regular Android phones/tablets).
• The LEANBACK_LAUNCHER filter is correctly attached to the main activity, satisfying Google Play's TV visibility requirements.

After generating the APK, double-check the AndroidManifest.xml to confirm:

• The LEANBACK_LAUNCHER intent filter is inside the <activity android:name="com.codename1.impl.android.UniAlephStub"> tag
• Only one instance of the touchscreen feature declaration exists (the default one added by Codename One)
