在Android上从浏览器下载具有特定内容类型的文件时，如何打开我的应用程序？

Question

I'd like to open my app when i download a file with specific mimeTipe, for example "application/pdf" using the browser. I tried adding this intent-filter in the manifest app but it doesn't work.

<intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.BROWSABLE" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="application/pdf" />
                <data android:scheme="https" />
</intent-filter>

Does the android browser send any intent that can help me to do that? I don' want to open my app by clicking on the file, I need to do this reading the GET header response and opening the app according to the Content-Type of the header.

What you want is called an Intent Filter . You can define a filter by file name, by URL, or by mime type.

In your case, Content-Type is a mime type. A Mime example might look like this in your AndroidManifest.xml :

<intent-filter . . . >
    <data android:mimeType="video/mpeg" android:scheme="http" . . . /> 
    <data android:mimeType="audio/mpeg" android:scheme="http" . . . />
    . . .
</intent-filter>
