Scan Barcode & QR code is a simple and fast code scanner with all the features a modern android app.

I completed the Udacity andriod course and decided to make my own app.

Reasons to make the Scanner app :

• The idea did not looked complex for a beginner to implement.
• I already knew a barcode scanner library which was pretty popular.
• All the similar apps on playstore had AD'S and I wanted a AD free version.
• The UI of these apps was also old, not updated for a time now so a Material Design solution was needed.

The libraries or resources used:

• Zxing-android-embedded: really easy to use and does what it says very efficently.
• cupboard: makes SQL vey simple. you should atleast read it usage. Read this for more info
• CodePath Android Cliffnotes: A crowdsourced resource for complete and up-to-date practical Android developer guides for any topic.
• youtube also helped as always.

Things I learned and implemented:

• RecyclerView with swipe actions.
• Database connectivity using SQLite.
• SharedPreferences.
• Intents.
• Countless hours of debugging and wow moments.

the app is available at https://github.com/shubhamnishad97/ScanBarcode-QRcode/raw/master/app/build/outputs/apk/app-debug.apk
