In order fro PayPal to work it may be necessary to update your android manifest

[nicolobozzato]

Something changed in the way the class manage the activity result you should try to update the manifest in this way
See this issue on the original sdk
braintree/braintree-android-drop-in#419
That link to this page
https://developer.paypal.com/braintree/docs/guides/drop-in/setup-and-integration/android/v4/#paypal

This are the modification necessary for the DropInActivity in the manifest

<activity android:name="com.braintreepayments.api.DropInActivity" android:exported="true" tools:node="merge" > <intent-filter tools:node="removeAll" /> <intent-filter> <action android:name="android.intent.action.VIEW" /> <data android:scheme="@string/braintree" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> </intent-filter> </activity>

I'll try to provide a PR to update the example and documentation as soon as I can, if you can do before even better

Hello,

I have used BraintreeBrowserSwitchActivity version 3.0.0.Now I have changed version 4.0.0 ,so BraintreeBrowserSwitchActivity doesn't work at all.App is crashing
Now I have changed manifest file and used com.braintreepayments.api.DropInActivity but Vault flow is not working with this.I can't pass amount 'null' or '0'.It simply doesn't accept it and app crash

With this I see another issue, if you're on Android 14 (only 14 doesn't happen on 15 and only on some devices) if a user cancels the PayPal payment it throws exception and doesn't come back to the app.
