我正在尝试通过 adb 测试 android 深度链接网址来启动我的应用程序

当我在 adb 中键入命令时:

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

我得到了这个错误:

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 }

但当我用 adb 键入命令时:

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

一切正常，我收到消息，我可以看到手机上的活动启动:

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

我的问题是，为什么我需要获取活动的完整路径，而不仅仅是包名称？因为当外部应用程序或浏览器尝试深度链接时，它们不会调用我的应用程序中的活动。

这是我的 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>

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

小开

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

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://"

小开

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
小开

Try this:

adb shell am start -a android.intent.action.VIEW -c android.intent.category.BROWSABLE -d 'yourdeeplink'


-a android.intent.action.VIEW -> action  -c android.intent.category.BROWSABLE -> category -d 'deeplink' -> data

and also you need to install the app first in order to register the deeplink.

The command

adb shell dumpsys package domain-preferred-apps

is also very helpful to print all active deep link handlers known to the system. If your app is missing here, there's obviously something wrong with your deep link setup.

Testing deep-linking by running adb shell command seems troublesome to me. So I tried an Easy Solution to reduce my task and time to test deep-linking multiple time using .bat file.

Step 1: First create a .txt file and paste here your ADB command -

adb shell am start -W -an android.intent.action.VIEW -d <Your URL> <Your Package>

and save the file changing .txt extension into .bat. Now you have just created your bat file to test deeplink. Try to use just one letter to name the bat file (Like I named d.bat , "d" for "deeplinking" for easy understanding) because it reduce your time of typing.

Step 2: Now open your terminal in Android studio and go to your bat file location and just type your file name (without extension) and press enter. For example cd your/bat/file/location/d here suppose "d" is your bat file name.

It will work spiffy!

You can test your deeplink from Android Studio interface.

enter image description here

  1. Select Tools > App Links Assistant.
  2. Click Test App Links in the App Links Assistant.
  3. Enter the URL you want to test in the URL field, for example, http://recipe-app.com/recipe/grilled-potato-salad.
  4. Click Run Test.

I found Savas Adar's answer the most friendly to use, also makes much more sense to have an inbuilt tool for that purpose.

Just use that!

I have three quick disclaimers about the App Links Assistant which are missing in his answer and a comment was too long.

  1. Open App Links Assistant. I couldn't find it in the Tools menu. So double press Shift and type App Link Assistant to run it from Android Studio

  2. Pressing "Run Test" would clear the edit text box so I found myself having to copy and paste my link every time I wanted to re-try the test. Foolish of myself not reading the text literally above it saying that after running a test a Run Configuration gets created with the previous url attached to it. (Top of the screen, left of the device menu). Just select the run configuration with the url you want.

  3. I found that pressing "Run Test" would restart the app unlike the ABD approach which is no biggie (just slower) until I wanted to debug. I ran the app in the debug mode and then pressed Run Test which would stop my debugging sessions and restart the app...

Solution is to choose the Run Configuration from point 2, and just run it as a debug.

小开

The best way I found is through Android Studio itself.

  1. Open the Run/Debug Configurations dialog by selecting Edit Configurations... option like in the image below: open 'Run/Debug Configurations' dialog

  2. After that add a new configuration with options like in the below image (if you're using Firebase Dynamic Links then enter your dynamic link's short link in the URL field else enter your deep link instead in the URL field): Options in the 'Run/Debug Configurations' dialog

  3. After that, you'll find the run configuration, select it, and just press Run: enter image description here

Add as many run configurations for each link you want to test.

If your deeplink has http or https scheme you can use the google text box in Android:

enter image description here

Just copy your deeplink there

Search Google Play for DeepLink. Download apk (via other sites that support downloading). Then install the application on emulator. For instance, https://play.google.com/store/apps/details?id=com.waterbottle.testdeeplink.

Following should work

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

Here

example://gizmos

is the URI scheme that you have setup.

But if you want to pass additional parameters to URI scheme and test it,

example

example://gizmos?parameter1=23&parameter2=test

then the command would be,

adb shell 'am start -W -a android.intent.action.VIEW -d "example://gizmos?parameter1=23&parameter2=test"' com.myapp
