ATTENTION:
- You need to have google-play-services.jar in your additional libs folder
- You need to have android-support-v4.jar in your additional libs folder
- You need to have android-support-v7-appcompat..jar in your additional ibs folder. Especially the app must be prepared to use AppCompat. So follow the apcmpat tutorial.

I´ve used Example1 of the AppCompat-Tutorials and used the Button in the layout to trigger a Barcodescan

See it in action

Tried a Samsung 8" Tablet (SM-T335). It does not recognize a barcode here. No crash but no detection.

 

[DonManfred]

Tried a Samsung 12,1" Tablet (SM-P900). Works fine.

Tried a Samsung 12,1" Tablet (SM-P900). Works fine.

Works perfectly on my 7" Samsumg GT-P3100 with Android 4.0.4 with the change that I have made as per post #20
Also now working on my Samsung S4 mini with KitKat

 

[Wolli013]

Samsung S3 work fine with

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat"/>

<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

Samsung4 Tab not work, not Autofocus!

[incendio]

Is this lib need to run with appcompat?

I tried without it, my codes only like these

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("b4a4lay1")
End Sub

Layout is from this example. I have google-play-services.jar, android-support-v4.jar & android-support-v7-appcompat.jar in my Lib folder.
Libraries are Core & MaterialBarcodeScanner ver 1.00, got these error.

Yes

 

[luke2012]

@DonManfred thanks for this great library.
Is it possible to open a Play store App using a barcode ?

 

[DonManfred]

It is up to you what you do when you receive a barcode...
For sure you can call a intent which calls google play.

Sorry I mean a QR CODE.

 

[DonManfred]

Sorry I mean a QR CODE.

Does not make a difference. The answer is the same.

It is up to you to react when you receive the text from a QR-Code.
