简而言之，当我单击文件管理器中的任何视频文件时，这会将我的应用程序显示为播放该视频的选项.当用户点击我的应用程序时，这将打开一个特定的活动并开始播放该文件.我该怎么做?

in short, when I click any video file in file manager, this will show my app as an option for playing that video. When user click on my app this will open a particular activity and start playing that file. How can I do this?

推荐答案

将下面的代码添加到inside activity(that you want to open) inside manifest:

Add the below code to inside activity(that you want to open) inside manifest:

        <intent-filter>
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <data android:mimeType="video/*"/>
            <data android:scheme="content"/>
            <data android:scheme="file"/>
        </intent-filter>

在您的活动中使用以下代码以获取文件的 uri.我已经在 exoplayer 中测试了路径.

use below code to your activity to get the uri of your file. I have tested the path in exoplayer.

Uri uri = getIntent().getData();
