I am trying to test android deep link urls through adb to launch my app

37

When I type the command in adb:

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

I get this error:

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

But when I type the command in adb:

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

Everything works fine and I get the message and I can see the activity launch on the phone:

Starting: Intent { act=android.intent.action.VIEW dat=example://gizmos cmp=com.myapp.activity.DeepLinkActivity }
Status: timeout
Activity: com.myapp.activity.DrawerActivity
Complete

My question is why do I need to get full path of my activity and not just package name? Because when the external apps or browser will try to deep link they will not invoke the activity in my app.

This is my AndroidManifest.xml

<activity
        android:name=".activity.DeepLinkActivity">
        <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="example"
                  android:host="gizmos" />

        </intent-filter>
</activity>
android
android-manifest
adb

You don't need to specify full path to your activity, but if you want to test whether you react properly to URI in your app just specify app package:

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

Also there is bug in command you provided - there should be example://gizmos not example:gizmos

The best solution for android studio is explained here: https://code.tutsplus.com/tutorials/how-to-enable-deep-links-on-android--cms-26317

TLDR : Android Studio --> Run --> Edit Configurations

Change Launch in Launch Options to "URL" and enter in the text field URL the correct url: "something://"

As the other answer mentioned, it should be "example://gizmos" and not "example:gizmos"

Alternatively, instead of using adb, you can test deep links directly on android using deep link tester app:

https://play.google.com/store/apps/details?id=com.manoj.dlt

No need to mention any package name or component name. Just type the deep link and fire.

I've found testing deep links through adb to be cubersome and difficult at times. Hence, I've built this small app to do it.

Your command is incorrect because you are trying with an incorrect package name, Instead of com.myapp.activity.DeepLinkActivity you have to write only the package name specified in build gradle(Module: app) by 'application Id' e.g if your applicationId is com.companyname, then your command would be like this:

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

Just in case someone else has the problem that I had, namely that adb shell am start ... does not work, if you have a file:///... or content://...URI in your intent filter that has a mime type specified, for example

<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:scheme="file" />
  <data android:mimeType="text/plain" />
  <data android:host="*" />
</intent-filter>

You need to specify the mime type on the command line by using the -t parameter:

adb shell am start -W -a android.intent.action.VIEW -d "file:///sdcard/myfolder/myfile.txt" -t "text/plain" com.myapp

or else you get the same error message as the OP.

Based on the experience I just had I recommend using this list of available adb commands. It seems to be more recent than the help texts from the shell of my test device running Android 8.

Here is the command

adb shell am start -d your-deep-link

Example

adb shell am start -d rm://yoursettingpage/v1
