安卓：在使用摇篮打造packageNameSuffix脚本时SearchableInfo为null [英] Android: SearchableInfo is null when using packageNameSuffix in Gradle build script

问题描述

我遇到的方法 getSearchableInfo 总是在搜索查看如果我用 packageNameSuffix 在项目的摇篮构建脚本。

I encountered that the method getSearchableInfo always returns null during SearchView initialization if I use the packageNameSuffix in the project's Gradle build script.

搜索查看初始化：

final SearchManager searchManager = (SearchManager) context.getSystemService(Context.SEARCH_SERVICE);
SearchableInfo info = searchManager.getSearchableInfo(componentName);
mSearchView.setSearchableInfo(info);

项目的的build.gradle：

android {
    [...]
    buildTypes {
        debug {
            packageNameSuffix ".debug"
            versionNameSuffix "-debug"
            signingConfig signingConfigs.debug
        }
        [...]
    }
}

如果不使用包的后缀，给定的组件名是 ComponentInfo {} com.example.android/com.example.android.MapActivity 和搜索查看，以及与其相关的 SuggestionsProvider 做工精细。

If the package suffix is not used, the given componentName is ComponentInfo{com.example.android/com.example.android.MapActivity} and the SearchView as well as its associated SuggestionsProvider work fine.

但是，如果 packageNameSuffix 设置为调试，给定的组件名是 ComponentInfo {com.example.android.debug / com.example.android.MapActivity} 和 SearchManager的收益空的，而不是返回各自的 SearchableInfo 对象。

But if packageNameSuffix is set to ".debug", the given componentName is ComponentInfo{com.example.android.debug/com.example.android.MapActivity} and the SearchManager returns null, instead of returning the respective SearchableInfo object.

有谁知道如何得到正确的 SearchableInfo 从 SearchManager的？谢谢！

Does anyone know how to get the right SearchableInfo from the SearchManager? Thanks!

尤金·马丁诺夫在评论中提到这behaviur可能有做的不当或缺失当局重命名的东西。但我也配置了当局的生成依赖型的命名，我在战后初期为简单起见，省略。

Eugen Martinov mentioned in the comments that this behaviur could have to do something with an improper or missing authorities renaming. But i also configured a build type dependent naming of the authorities, that i omitted in the initial post for the sake of simplicity.

项目的的build.gradle：

android {
    [...]
    sourceSets {
        debug {
            java.srcDirs = [
                'src/main/java'
            ]
            java.srcDirs = [
                'src/debug/res',
                'src/main/res'
            ]
        }
        release {
            java.srcDirs = [
                'src/main/java'
            ]
            java.srcDirs = [
                'src/release/res',
                'src/main/res'
            ]
        }
        [...]
    }
}

的src /调试/ RES /价值/构建-config.xml中：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="cfg_app_name">App - Debug</string>
    <string name="cfg_authorities">com.example.debug.SuggestionsProvider</string>
    <string name="cfg_maps_key"><!-- some key --></string>
</resources>

的src /发行/ RES /价值/构建-config.xml中：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="cfg_app_name">App</string>
    <string name="cfg_authorities">com.example.SuggestionsProvider</string>
    <string name="cfg_maps_key"><!-- some other key --></string>
</resources>

的src / main / RES / XML / searchable.xml：

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:hint="@string/action_search_hint"
    android:label="@string/cfg_app_name"
    android:includeInGlobalSearch="false"
    android:queryAfterZeroResults="true"
    android:searchSuggestAuthority="@string/cfg_authorities"
    android:searchSuggestIntentAction="android.intent.action.VIEW"
    android:searchSuggestThreshold="3" />

同时安装调试（与 packageNameSuffix 选项），并在同一装置作品发布APK。我不明白像失败[INSTALL_FAILED_CONFLICTING_PROVIDER] ...但是前面已经说了， SearchableInfo 是一个错误空即可。

Installing both the debug (with the packageNameSuffix option) and the release apk on the same device works. I don't get an error like Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]... But as already said, SearchableInfo is null then.

同时安装APK withouth的在 packageNameSuffix 选项通向以下错误：失败[INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES] - 安装失败，因为该设备已经有一个应用程序同样的包，但不同的签名。

Installing both apk withouth the packageNameSuffix option leads into the following error: Failure [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES] - Installation failed since the device already has an application with the same package but a different signature.

或者我失去了一些东西？

Or am i missing something here?

推荐答案

我使用的产品口味是完全改变了包名。我发现，通过使用组件名（上下文PKG，类＆LT;＆GT; CLS）。构造我的搜索活动，我得到一个有效的SearchableInfo

I am using product flavors that completely changes the package name. I found that by using the ComponentName(Context pkg, Class<?> cls) constructor for my search activity I get a valid SearchableInfo.

SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchableInfo searchableInfo = searchManager.getSearchableInfo(new ComponentName(this, SearchActivity.class));

我也不得不调整我的供应商，所以我的搜索XML是每个味道目录和供应商在清单中列出每个味道，以及使用不同的包。
这是我的目录结构：

I also had to adjust my provider to use a different package so my searchable xml is in each flavor directory and the provider is listed in the manifest for each flavor as well. This is my directory structure:

src
  main
    AndoridManifest.xml
  flavor1
    res
      xml
        search.xml
    AndroidManifest.xml
  flavor2
    res
      xml
        search.xml
    AndroidManifest.xml

主/ AndroidManifest.xml中

    android:theme="@style/AppTheme">
    <activity

        android:launchMode="singleTask">
        <meta-data

            android:value=".ui.activity.SearchActivity"/>
    </activity>
    <activity android:name=".ui.SearchActivity" android:launchMode="singleTop">
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/search"/>
    </activity>

    <provider
        android:authorities=".provider.SuggestionProvider"
        android:name="com.example.main.provider.SuggestionProvider"
        android:exported="false"
        android:enabled="true"
        />
</applicaiton

flavor1 / AndroidManifest.xml中

    android:searchSuggestSelection="title LIKE ?"
    android:searchSuggestThreshold="0"
