How can I make ZXing Barcode Scanner compatible with 2.2 and above Android

I want ZXing Barcode Scanner compatible with android 2.2 and above.

What I did - I used Zing 2.3.0 in my application and its perfectly working in 4.0 and above

but when I run in android 2.2 and I click the button to start scanner the application got crashed.

What extra I need to implement ??

Note: I have added CaptureActivity project from zxing as a library in my project and CaptureActivity and MyProject in both the menifest file minsdk is 8 and targeted is 17

Solution

  • The code has not been written for Android 2.2 compatibility in a long time. You can go back further to find such a version. But I would encourage you to write your own app and just reuse the core library instead. Also there are very few Android 2.2 devices anymore, less than 1%. It is not really worth supporting.
