在 Android 上使用 Chrome 打开 android-app 方案

Question

I was wondering how I'd have to configure my app to open it with android-app://application.id ?

adb shell am start android-app://application.id

The URI_ANDROID_APP_SCHEME seems not to work as documented. Instead Chrome and Firefox only open a market:// link to my app.

For Chrome I found a documentation only describing the intent:// scheme.

When the intent filter contains the DEFAULT and BROWSABLE category it works with Firefox .

<intent-filter>
    <action android:name="android.intent.action.MAIN" />

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

Answer 1

You have to add <data../> describing URI in intent-filter for your component, like so,

<intent-filter>
   ...

   <data android:scheme="android-app"/>
</intent-filter>

and on your site part define intent like this

intent:#Intent;scheme=android-app;package=your_package;end

UPDATE. Didn't realize that scheme was a reserved one, although my solution works for any scheme you define. I looked up the sources of the Intent class it seems you have to define your URI like this

android-app://your_package

OR

android-app://your_package/ 
#Intent;action=com.example.MY_ACTION;end

First line of the parseUri method in the Androids Intent class

final boolean androidApp = uri.startsWith("android-app:");

Worth to mention: This scheme was added on API 22.

I've tested it works with a tag, and as @tynn mentioned in the comments also for window.open() and location.href and not working from the address bar in Chrome.
