Question

我搜索了这个问题，但没有找到任何与我的问题相关的答案。我希望以前有人能解决这个问题并且可以帮助我（ - ：。

我有一个android工作室项目，里面有'libs'文件夹 aar库（例如：some_lib.aar）。
在aar库中，我有'mipmap'和'raw'文件夹内部资源（'mipmap'有PNG，'raw'有声音文件名为：sound.wav）。
在我的项目中，我正在尝试从mipmap中加载一些* .png文件来自'raw'文件夹的声音文件如下：

Uri soundUri = loadSoundFromLocal(context, "sound.wav");

private Uri loadSoundFromLocal(Context context, String sound) {             

    try {

        // Get resource id.
        boolean isGmeResource = true;
        int soundResource = UtilsResources.getResId(sound, R.raw.class);
        if (soundResource == -1 || soundResource == 0) {

            soundResource = UtilsResources.getIdentifier(context, sound, "raw");
            if (soundResource != -1 && soundResource != 0) {
                isGmeResource = false;
            }
        }

        // Create the uri string for the sound file.
        if (soundResource == -1 || soundResource == 0) {

            return RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        } else {                                                    

            return UtilsResources.getUriFromResId(context, soundResource, isGmeResource);
        }

    } catch (Exception e) { 
        return null;
    }
}

public static int getResId(String resourceName, Class<?> c) {

    if (TextUtils.isEmpty(resourceName)) { return -1; }
    if (c == null) { return -1; }

    try {

        Field field = c.getField(resourceName);
        if (field == null) {
            return -1;
        }

        return field.getInt(null);                      

    } catch (Exception e) {
        return -1;
    }
}

public static int getIdentifier(Context context, String name, String defType) {

    String appPackageName = UtilsData.getAppPackageName(context);
    if (TextUtils.isEmpty(appPackageName)) {            
        return -1;
    }

    if (context.getPackageManager() == null) { return -1; }     
    if (TextUtils.isEmpty(name)) { return -1; }     
    if (TextUtils.isEmpty(defType)) { return -1; }

    try {

        Resources resources = context.getPackageManager().getResourcesForApplication(appPackageName);
        if (resources == null) {
            return -1;
        }

        return resources.getIdentifier(name, defType, appPackageName);      

    } catch (NameNotFoundException e) {

        // Should never happen
        UtilsLogger.e(LOG_TAG, (e != null)? e.getMessage() : "Could not get package name");
        return -1;

    } catch (Exception e) {

        UtilsLogger.e(LOG_TAG, (e != null)? e.getMessage() : "Could not get identifier version code");
        return -1;
    }
}

我有这样的例外（也适用于'mipmap'文件夹）：

我必须说当图书馆作为模块而不是作为模块导入时 * .aar文件一切正常！
我需要将库导入为* .aar文件，所以我卡住了，需要一个解决方案尽快解决！
我的代码好吗？如果没有，这里有什么问题？

感谢您提前获得任何人的帮助希望我能尽快得到答案（ - ：

Android Studio - 无法从位于libs文件夹（或mipmap文件夹）中的some_lib.aar文件加载资源
