android-obd-reader

Android OBD-II reader designed to connect with Bluetooth Elm327 OBD reader.

I'm still migrating things over here, so keep with me :-)

Prerequisites

• JDK 7
• Android Studio 0.8.1
• Gradle 1.12
• Android SDK (API 19, Build tools 19.1)

Test with device

Be sure to have the device connected to your computer.

cd whatever_directory_you_cloned_this_repository
gradle clean build installDebug

Test with OBD Server

If you want to upload data to a server, for now, check the following:

• OBD Server - a simple implementation of a RESTful app, compiled into a runnable JAR.
• Enable the upload functionality, by defining private static final boolean UPLOAD = true; in MainActivity.java;
• Set proper endpoint address and port in class UploadAsyncTask defined in MainActivity.java.

Tested on

• Samsung Galaxy S4 (Android 4.4.2)

Changes in this Branch

• introduced GPS information
• introduced some of the missing connections between the preferences and the actual code
• modified the way data is uploaded to the server:
• 1. not every reading has long/lat and time. This is a waste of data upload. Data is compacted into a common structure and then it is uploaded in one go
• taken care of cases where the server is not responding: created a local database where data is temporarily stored
• the interface does not have a table with all data but a textview with only the current data: this is much easier to read
• the font color has been changed to greyish to white (I could not read it)
• the names of the views in the interface have now a positional name (row1_column2). This is because in the future it would be great to have the allocation of data flexible (so that you can change what is displayed where
• other minor changes

Issues

The data displayed is wrong. This is not an issue with this branch. It is something that happens also in the original repository.
