Some problems and suggestions

[whc2001]

Although I think the main project and this tool have been abandoned, I still found it quite handy. Currently I found some problems including:

• It no longer compiles on newer version of Android Studio due to Gradle and SDK/library versions
• Getting part info after scanning barcode will cause an empty error dialog, which is because the application is doing PUT while GET should be used when requesting

Also I would like some additional buttons that can add/remove multiple in addition to +1/-1 since I need to draw out multiple pieces of a specific part sometimes.

Seems like there are still many pull requests pending, and I have nearly zero experience in Android developing, but I would still try to fix, implement and push.
