深层链接意图不起作用

Question

I followed the insttructions on https://developer.android.com/training/app-indexing/deep-linking.html , but when I want to trigger the intent through adb with:

adb shell am start
           -W -a android.intent.action.BROWSEABLE
           -d "http://example.com/gizmos" com.myapp.android

I just get

Error: Activity not started, unable to resolve Intent { act=android.intent.action.VIEW dat=example://gizmos flg=0x10000000 pkg=com.myapp.android }

<activity
        android:name=".activities.DeepLinkActivity"
        android:label="@string/title_activity_deep_link">
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />

        <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="http"
                android:host="example.com"
                android:pathPrefix="/gizmos" />
        </intent-filter>
    </activity>

Have I made any obvious mistakes?

Answer 1

EDIT:

Ok first make sure that your package is reachable by adb:

adb shell am start -n com.example.simon.test/.activities.MainActivity

Then to accept multiple data tags you need different intent filters ( that's the way it worked for me unlike all the other examples I've seen on the net ). Eg:

<intent-filter>
    ...
    <data android:scheme="http"
          android:host="example.com"/>
</intent-filter>
<intent-filter>
    ...
    <data android:scheme="http"
          android:host="example.com"
          android:pathPrefix="/gizmos"/>
</intent-filter>

NOTE that in the above example the pathPrefix starts with a forward slash !

I am not sure why Google's Docs are so misleading or maybe that was for some different version of adb, but the above changes worked perfectly for me. This helped: Source

This is how I made the Chrome browser route specific links to my app:

<activity
    android:name=".activities.DeepLinkActivity"
    android:label="@string/app_name">
    <!-- Accept chrome links -->
    <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="http"
              android:host="example.com"
            android:pathPrefix="/"/>
    </intent-filter>
    <!-- Accept adb data flag -->
    <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="http"
              android:host="example.com"/>
    </intent-filter>
</activity>

NOTE The 1st filter works on Google Chrome while the 2nd one works on the ADB.

NOTE2 The app choice menu won't be shown if the link is entered into the browser's address bar. It has to be a <a href="http://example.com"></a> link in side some page.

In my opinion everything here is rather blurry and really not how I expected it all to work. But that's how it works on my device. Hope this helps (and works) for you too.

Answer 2

After some tests this is what worked for me:

    <activity android:name=".activities.MainActivity">
        <intent-filter android:label="@string/app_name">
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="http"
                  android:host="www.example.com"
                  android:pathPrefix=""
                />
            <data android:scheme="myschema"
                  android:host="example"
                  android:pathPrefix=""
                />
        </intent-filter>
    </activity>

This works when clicking any link in the browser such as " http://www.example.com ", " http://www.example.com/ " or " http://www.example.com/whatever ". The same with "myschema://example/whatever".

Also works with adb using this command (with any of those URLs):

adb shell am start -W -a android.intent.action.VIEW -d "http://www.example.com" com.example

Hope it helps to get you started.

When everything is working you will probably want to configure a different pathPrefix for different activities.

Answer 3

In my case, I was putting deep linking intent filter in MainActivity which is also main launcher. That caused the problem.

After I created another separate activity and put intent filter there, it solved the problem. Hope this can help others who are facing the same issue.

Answer 4

In my case, I am using an emulator and not an actual usb connected device, and hence I had to change -d to -e, like so :

adb shell am start -W -a android.intent.action.VIEW -e "http://www.example.com" com.example

Note the -e before the deep link.

Answer 5

First, read @user3249477's answer on this page.

I just wanted to add that instead of what he wrote, you can condense it by using pathPattern:

<activity
    android:name=".activities.DeepLinkActivity"
    android:label="@string/app_name">
    <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="http"
              android:host="example.com"
            android:pathPattern=".*"/>
    </intent-filter>
</activity>

The ".*" matches both the empty string and "/", so both cases are covered. If you end up trying to handle multiple scheme's and host's this becomes especially important, so you don't have to spam a powerset of {http, https} X {"", "/"} X {"foo", "bar", etc.}

Answer 6

Make sure your URL is in this format (with the cap letters replaced by your own):

android-app://COM.YOUR.APP.IDENTIFIER/SCHEME/HOST?somegetparams

The adb tool does not require this format. With the above you can now put it in an src, or an href, like so:

<iframe src="android-app://COM.YOUR.APP.IDENTIFIER/SCHEME/HOST?somegetparams"> </iframe> 
<a href="android-app://COM.YOUR.APP.IDENTIFIER/SCHEME/HOST?somegetparams">LINK</a>

Answer 7

在我的情况下，我在 URL 中有一个端口 8075，我删除了它并且它工作正常

Answer 8

./adb shell am start -n packagename/.splash.SplashActivity -d "schemeName://content"

Answer 9

Use adb shell am start -W -a android.intent.action.VIEW -d " http://example.com/gizmos " com.myapp.android

it will work.

Answer 10

Thanks Simas for your response i would like to add some clarification:

• after testing your activity with this command:

  adb shell am start -n com.example.simon.test/.activities.MainActivity

• You will need to test your deeplinks ,after adding the intent filter to your AndroidManifest.xml file (lines are below):

  ... ...

so this is the adb command with which you can test :

adb shell am start -W -a android.intent.action.VIEW -d "http://example.com/gizmos" com.example.packageid

and

adb shell am start -W -a android.intent.action.VIEW -d "http://example.com" com.example.pakageid

如果您没有权限问题，则可能与API级别有关

Answer 12

Use this intent filter instead,

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

<!-- Accepts URIs that begin with "example://gizmos” -->
<data
   android:host="gizmos"
   android:scheme="example" />
</intent-filter>

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

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

<!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
<data 
    android:host="www.example.com"
    android:pathPrefix="gizmos"
    android:scheme="http" />
</intent-filter>
