概要

UnityEngine.Application.temporaryCachePath

と同様の文字列を返す関数を自作してみる

ソースコード

using UnityEngine;

public static class AndroidUtils
{
    public static string GetExternalCacheDir()
    {
        using ( var player = new AndroidJavaClass( "com.unity3d.player.UnityPlayer" ) )
        using ( var activity = player.GetStatic<AndroidJavaObject>( "currentActivity" ) )
        using ( var file = activity.Call<AndroidJavaObject>( "getExternalCacheDir" ) )
        {
            if ( file == null ) return string.Empty;
            return file.Call<string>( "getAbsolutePath" );
        }
    }
}

使用例

using UnityEngine;

public class Test : MonoBehaviour
{
    private void Awake()
    {
        Debug.Log( AndroidUtils.GetExternalCacheDir() );
    }
}
