How can I access preview frames when using camera? Is there a similar function to Android API's onPreviewFrame (byte[] data, Camera camera). I'd like to develop a scanner app like barcode scanner, but scanning other things. So, I need to retrieve preview frames of camera component but don't know hot to do that.
Hello! You would need to check if it's possible to do and if so - serach for PhoneGap plugin online as there is no standard method to do that.
It seems that PhoneGap doesn't offer that kind of method. Is there an alternative way?
Another way is to use JS to do that, but it would need to be coded by you.
Thank you for your help! Can you tell me more? Is there any sample JS code? what keyword can I search with?
Hello,
You would have to create a PhoneGap plug-in implements the needed functionality. You can write it using API Android in Java.
I'd like to make it clear. If I make a PhoneGap plug-in using Android native API in Java, does it still work in iOS device? Also, it can be a hybrid app as well as web app? I'm new to appery but appery seems very flexible!
Hello!
[quote:]If I make a PhoneGap plug-in using Android native API in Java, does it still work in iOS device?[/quote] no, it won't work on iOS devices, you would need to create one more plugin for iOS
[quote:]Also, it can be a hybrid app as well as web app?[/quote] you can't use any PhoneGap plugin for web app. For web app you can use only HTML5 features.
