azureb2c is not working on android emulator

Juan Rivero 20

azureb2c is not working on android emulator but is working on windows Machine. When I run the android emulator and the maui blazor app is running on the Android emulator, I click on login and it looks like it will connect to the azureb2c url and display the login page, but I only see a blank page. I copy and paste the azureb2c url on my laptop browser and it shows the login page, but not on the android emulator.

Thank you for posting your query on Microsoft Q&A, from above description I could understand that your application sign in is not working for Azure B2C on Android emulator.

Please do correct me if this not the issue.

To start with Kindly validate the AndroidManifest.xml and add BrowserTabActivity activity to the application body:

<!--Intent filter to capture System Browser or Authenticator calling back to our app after sign-in--> <activity
    android:name="com.microsoft.identity.client.BrowserTabActivity"> <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="msauth"
            android:host="Package_Name"
            android:path="/Signature_Hash" /> </intent-filter> </activity>

Please do let me know by responding in the comments section if the issue persist.

Thanks,

where do you place this change on the AndroidManifest.xml?


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application android:allowBackup="true" android:icon="@mipmap/appicon" android:roundIcon="@mipmap/appicon_round" android:supportsRtl="true" android:usesCleartextTraffic="true"></application>

Hi Akshay,
Where do I find the package name and the signature hash, and where do I insert the code on the AndroidManifest.xml?

 <activity            android:host="Package_Name" android:path="/Signature_Hash" /> </intent-filter> </activity>

@Juan Rivero

Use your Azure portal Package name to replace android:host=. value. It should look like com.azuresamples.msalandroidapp.

Use your Azure portal Signature Hash to replace android:path= value. Ensure that there's a leading / at the beginning of your Signature Hash. It should look like /1wIqXSqBj7w+h11ZifsnqwgyKrY=.

You can find these values in the Authentication blade of your app registration as well.
