AIDLServices

Displays data related to TYPE_ROTATION_VECTOR sensor using AIDL

• Consist of aidlsdk module that expose sensor data
• Sample app to show the sensor data

Usage

aidlsdk module

• Bind Service

class SensorService : LifecycleService() //Bound Sevice with exposes sensor data using liveData

 val sensorData = MutableLiveData<FloatArray>() //Exposes rotational vector sensor data to the observer.

App usage

• Add in your apps AndroidManifest.xml

<service
       android:name="com.vikasmane.aidlsdk.SensorService"
       android:enabled="true"
       android:exported="true" />

• To use the service in your app bind to the service

private fun bindService() {
        rotationalServiceIntent = Intent(this, SensorService::class.java)
        rotationalServiceConnection = object : ServiceConnection {
            override fun onServiceConnected(componentName: ComponentName?, binder: IBinder?) {
                val orientationInterface = RotationalDataInterface.Stub.asInterface(binder)
                sensorDataText.text = orientationInterface?.rotationalData
                isServiceConnected = true
                updateButtonText()
            }

            override fun onServiceDisconnected(componentName: ComponentName?) {
                isServiceConnected = false
                updateButtonText()
            }
        }
        bindService(
            rotationalServiceIntent,
            rotationalServiceConnection,
            Context.BIND_AUTO_CREATE
        )
    }

• The actual sensor listener is attached on calling rotationalData of orientationInterface after service is connected

orientationInterface?.rotationalData //Starts the sensor listener

• This will start pushing the sensor data into the sensorData liveData

SensorService.sensorData.observe(this, {
            sensorDataText.text = it.contentToString()
        })
