android - 如何让我的应用显示在 Google Now“手机/平板电脑搜索”页面中

Question

我一直在尝试从我的应用中获取信息以显示在 Google Now 搜索页面中。我似乎已经设置了搜索建议，当我在平板电脑上进行平板电脑搜索时，我什至看到我的提供程序已执行。但什么也没有出现。

显现

    <activity
        android:name=".SearchActivity"
        android:label="@string/app_name"
    >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
        </intent-filter>
        <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" />
    </activity>
    <activity
        android:name=".SearchViewActivity"
        android:label="@string/app_name"
    >
        <meta-data android:name="android.app.default_searchable" android:value=".SearchActivity" />
    </activity>
    <provider
        android:authorities=".MyContentProvider"
        android:name="org.test.MyContentProvider"
        android:exported="true"
        android:label="@string/app_name"
        android:logo="@drawable/ic_launcher"
    />

可搜索的.xml

<searchable
xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/lbl_apptricity_search"
android:hint="@string/hnt_search"
android:searchSuggestAuthority="com.apptricity.asset.provider.AssetContentProvider"
android:searchSuggestIntentAction="android.intent.action.VIEW"
