如何使用XML中的Gradle Placeholder ApplicationId创建唯一的ContentProvider权限

我有以下可搜索的XML声明:

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:label="@string/app_name"
    android:voiceSearchMode="showVoiceSearchButton"
    android:includeInGlobalSearch="true"
    android:searchMode="queryRewriteFromText"
    android:searchSuggestAuthority="com.mypackage.MyRecentSuggestionsProvider"
    android:searchSuggestSelection=" ?"
    android:hint="@string/search_hint">

</searchable>

现在是ContentProvider本身:

package com.mypackage.contentProviders

import android.content.SearchRecentSuggestionsProvider
import com.mypackage.BuildConfig
     class MySuggestionsProvider : SearchRecentSuggestionsProvider() {

        val AUTHORITY = BuildConfig.APPLICATION_ID + ".MySuggestionsProvider"
        val MODE = SearchRecentSuggestionsProvider.DATABASE_MODE_QUERIES

       init{
            setupSuggestions(AUTHORITY, MODE)
        }
    }

现在的问题是,我在Gradle中有3种风格,所以ContentProvider类中定义权限的行使用应用程序ID使其唯一,这样所有3种风格都可以同时存在于设备上。我记得,两个应用程序不能有重复的权限。

现在讨论我的问题:我不想重写每种风格的searchable.xml,只想为每种风格声明另一个权限。我宁愿这样做:

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:label="@string/app_name"
    android:voiceSearchMode="showVoiceSearchButton"
    android:includeInGlobalSearch="true"
    android:searchMode="queryRewriteFromText"
    android:searchSuggestAuthority="{applicationId}.MyRecentSuggestionsProvider"
    android:searchSuggestSelection=" ?"
    android:hint="@string/search_hint">

</searchable>

我们经常这样做,因为Android清单是一个占位符。是否无论如何,我不必为内容提供程序创建不同的XML声明,而是以某种方式使其每种风格都具有唯一性?
