sensorlog's Introduction

SensorApp

This app has been developed for collecting raw sensor data in android devices.

It listens to changes in the following sensors:

Accelerometer sensor
Light sensor
Screen on/off
Battery charging/discharging
Power on/off

Various optimizations on the client were also used on client to bring down the battery consumptions. (It's less than 2% per 24hrs in most phones)

The app uses FirebaseDB, so inorder to make it run, you will need to configure FIREBASE_URL in strings.xml, add google-servies.json, as mentioned in the link https://firebase.google.com/docs/android/setup?authuser=0

Currently the app syncs data upon it's launch and all the data is not synced rather the data is contracted as specified in classes like AccDataContracted.java etc.

TODOs :

Code commenting and cleaning
instead of just supporting firebase-db, support rest endpoint where the user of the sdk can push the sensor data
Turn this more into an sdk

Issue on syncing in background

Whenever the app tries to sync in background or when we open, it gives an error of "Sync Account Error".
Could you give a small flow diagram of how the flow should be when sending data to server on app launch or when in background.
This will make it easy to debug.
Thanks

Issue in GlobalVariable

private void performLogin(User user) {
Context context = getApplicationContext();

    globalVariable = GlobalVariable.getInstance();
    globalVariable.setUser(user);
    globalVariable.setContext(context);
    SyncUtils.CreateSyncAccount(this);
    SyncAdapter.performSync();
    if (!(dataStoreHelper.getSleepData().getSu() && dataStoreHelper.getSleepData().getEu())) {
        scheduleNotification();
    }
    startActivity(new Intent(MainActivity.this, ViewDataActivity.class));
    finish();

}

In above Function performLogin(...) , when you try to get the instance of GlobalVariable, getContext() is called before setting the context which is done after getting the instance.
I have resolved it by setting the firebase parameter outside the private constructor so that the context is set first and then firebase params are set using the context parameter.
