Android app linking fails due to empty hosts

[QuentinFarizon]

Using the latest version of this plugin, app linking verification isn't launched due to extraneous empty hosts

By "isn't launched", I mean:

• verification process is not event launched : there is no logcat entry for SingleHostAsyncVerifier nor IntentFilterIntentOp
• adb shell dumpsys package d show no entry for my app (whereas when a verification fails there is at least an entry with "ask")

Not working :

            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:host="www.boks.app" android:pathPrefix="/" android:scheme="https" />
                <data android:host=" " android:pathPrefix="/" android:scheme=" " />
                <data android:host=" " android:pathPrefix="/" android:scheme=" " />
                <data android:host=" " android:pathPrefix="/" android:scheme=" " />
                <data android:host=" " android:pathPrefix="/" android:scheme=" " />
            </intent-filter>

Working :

            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:host="www.boks.app" android:pathPrefix="/" android:scheme="https" />
            </intent-filter>

I have tested this on 3 different Android devices and Android versions.

I think you should find a way to remove the entries for extra hosts when these hosts are not defined. Or maybe if they were empty instead of containging a space ?

I am debugging a similar issue in a cordova app at the moment. The app links haven't been working for past few weeks.
Did you find a workaround for this issue ??
Or at least how were you able to test by removing the entries with blank values... ..

Is there a way to manually change the "generated" AndroidManifest.xml file in the ionic/cordova build process ???

I applied a patch on node_modules using the patch-package mechanism : https://www.npmjs.com/package/patch-package Not ideal, but it works : diff --git a/node_modules/ionic-plugin-deeplinks/plugin.xml b/node_modules/ionic-plugin-deeplinks/plugin.xml index e23ff60..b245b3b 100644 --- a/node_modules/ionic-plugin-deeplinks/plugin.xml +++ b/node_modules/ionic-plugin-deeplinks/plugin.xml @@ -53,10 +53,6 @@ <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="$DEEPLINK_SCHEME" android:host="$DEEPLINK_HOST" android:pathPrefix="$ANDROID_PATH_PREFIX" /> - <data android:scheme="$DEEPLINK_2_SCHEME" android:host="$DEEPLINK_2_HOST" android:pathPrefix="$ANDROID_2_PATH_PREFIX" /> - <data android:scheme="$DEEPLINK_3_SCHEME" android:host="$DEEPLINK_3_HOST" android:pathPrefix="$ANDROID_3_PATH_PREFIX" /> - <data android:scheme="$DEEPLINK_4_SCHEME" android:host="$DEEPLINK_4_HOST" android:pathPrefix="$ANDROID_4_PATH_PREFIX" /> - <data android:scheme="$DEEPLINK_5_SCHEME" android:host="$DEEPLINK_5_HOST" android:pathPrefix="$ANDROID_5_PATH_PREFIX" /> </intent-filter> </config-file>

Same issue, empty hosts entries break app linking completely on Android 12.

[geshub]

In my case it's not breaking app linking but I can see issues for the empty hosts on the google play console in the deep links category.

[sirineKr]

Same case as @geshub. Errors in deep link view in google play console due to empty host.

[baraaksayeth]

same as @geshub. I have errors in play console about deep link.

Is there any way to solve it?

[geshub]

@baraaksayeth I fixed it by filling all the empty deeplinks hosts, schemes and prefixes with dummy values.

[baraaksayeth]

fixed it by filling all the empty deeplinks hosts, schemes and prefixes with dummy values.

@geshub Is it possible to fill all empty deeplink with the same value?

[geshub]

@baraaksayeth I think it's safer to do it with links you're not using than repeating the same. I've got no errors on my deeplinks on google play console.

@geshub Is there any promblems with verification domain if I fill with empty host etc.?

[geshub]

@baraaksayeth probably yes, I filled it with dummy directories on my existing and verified domain.

[baraaksayeth]

@geshub so you fill only with different path but the domain is still same right?

[geshub]

@geshub so you fill only with different path but the domain is still same right?

@baraaksayeth correct

[baraaksayeth]

I don't know why it still happens to me
