Is your manifest correct:

Caused by: com.google.android.gms.common.GooglePlayServicesMissingManifestValueException: A required meta-data tag in your app's AndroidManifest.xml does not exist. You must have the following declaration within the <application> element: <meta-data android:name="com.google.android.gms.version" android:value="@Integer/google_play_services_version" />

 

[Xfood]

add this in the manifest


AddApplicationText(
<meta-data android:name="com.google.android.gms.version" android:value="@Integer/google_play_services_version" />
)

I`m running the example as is...

 

[james_sgp]

add this in the manifest


AddApplicationText(
<meta-data android:name="com.google.android.gms.version" android:value="@Integer/google_play_services_version" />
)

Added that line to the Manifest, but I still get the same error...

 

[Xfood]

try to attach here the project that we look at it.

I can`t upload the example as it's too large.
I'm running the example from here:
https://www.b4x.com/android/forum/threads/b4x-b4xpages-barcode-reader.120417/#content

 

[agraham]

That works fine as is for me. Have you tried downloading it again and starting afresh?

 

[james_sgp]

Downloaded a fresh copy, get a warning as it's using 'Target=29', but don`t change. Still get the same error...

I`m running B4A 11.50, no SDKs are showing to install.

 

[agraham]

no SDKs are showing to install.

That's sounds worrying because it means that you have probably run SDK Manager which is normally totally unnecessary and can cause problems if you do. The installation instructions explicitly warn against this. Try a new SDK following the instructions exactly.

I mean I used the B4ASdkManager, and nothing new is showing to install. Is that an issue?

Depends whether you have run it in the past and 'updated' anything. That example should run cleanly on a fresh install of both B4A and the recommended SDK.
