Android文件关联不起作用(意图过滤器，按扩展名) [英] Android file associations not working (intent filter, by extension)

问题描述

我一直在尝试将我的应用与vrtci文件扩展名相关联，但无法正常工作.我一直在互联网上寻找自己做错了什么，但没有任何帮助.这是我的AndroidManifest.xml中的部分:

I've been trying to associate my app with vrtci file extension, but it's not working. I've been looking across the internet to see what I've been doing wrong and nothing helped. Here is the section in my AndroidManifest.xml:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" android:theme="@style/Theme.AppCompat.Light">
    <activity
        android:name=".MainCardActivity"
        android:label="@string/app_name"
        android:configChanges="keyboardHidden|orientation|screenSize" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity android:name=".CardInstaller" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="content" />
            <data android:pathPattern=".*\\.vrtci" />
            <data android:mimeType="application/octet-stream" />
        </intent-filter>
        <!-- For http -->
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="http" />
            <data android:host="*" />
            <data android:pathPattern=".*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\.vrtci" />

            <data android:mimeType="*/*" />
        </intent-filter>
        <!-- For https -->
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="https" />
            <data android:host="*" />
            <data android:pathPattern=".*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\.vrtci" />

            <data android:mimeType="*/*" />
        </intent-filter>
        <!-- For file browsers and google drive -->
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="file" />
            <data android:host="*" />
            <data android:pathPattern=".*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\..*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\..*\\..*\\..*\\.vrtci" />
            <data android:mimeType="*/*" />
        </intent-filter>
    </activity>
</application>

推荐答案

所以我刚刚找到了一个对我有用的解决方案.

So I've just found a solution which did it for me.

使用方案"content"创建意图过滤器，完全不指定host元素.

Create intent-filter with scheme "content" and do not specify the host element at all.

     <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="content" />
            <data android:mimeType="*/*" />
            <data android:pathPattern=".*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\..*\\.vrtci" />
            <data android:pathPattern=".*\\..*\\..*\\..*\\..*\\.vrtci" />
        </intent-filter>
