brainflowandroidtest's Introduction

Disclaimer: this code can be used as a reference or starting point for your own projects, but it's a test application and doesn't pretend to be production quality

BrainFlow Android Dev and User Guides

Currently it supports:

Synthetic Board
OpenBCI Ganglion + WIFI Shield
OpenBCI Cyton + WIFI Shield
OpenBCI Cyton Daisy + WIFI Shield

BrainFlow may work on Android for other devices as well without any changes, but so far on Android we tested only devices above.

Limitations in Android Emulator

It's hard to configure Android Emulator to work with real boards, so in Android Emulator we recommend to use Synthetic Board and test real boards directly on real Android Device

brainflowandroidtest's Issues

app crashes with Android Studio 4.0.1

This line failes:

BrainFlowAndroidTest/app/src/main/java/com/example/brainflowplot/SettingsActivity.java

Line 49 in b780dbd

setPreferencesFromResource(R.xml.root_preferences, rootKey);

That class SettingsFragment is used in OnCreate:


    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.settings_activity);
        getSupportFragmentManager()
                .beginTransaction()
                .replace(R.id.settings, new SettingsFragment())
                .commit();

debug output:

This is not related to BrainFlow but to the shitty Android OS

Would like to add OpenBci support to my does-them-all android app: https://www.robosoft.de/eegcenter/
Ideas welcome :-)
