Android build fails with AGP 9.x: proguard-android.txt not found

[dimer47]

Description

The Android build fails when using Android Gradle Plugin 9.x because proguard-android.txt was removed in recent AGP versions. Only proguard-android-optimize.txt is available.

Error

Execution failed for task ':capacitor-community-native-audio:...'
> proguard-android.txt not found

Fix

In android/build.gradle, line 33:

- proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
+ proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

This is backwards-compatible — proguard-android-optimize.txt has been available since early Android SDK versions.

Environment

• @capacitor-community/native-audio: 8.0.0
• Android Gradle Plugin: 9.2.1
• Gradle: 9.4.1
• Capacitor: 8.x
