Android Wear with Google fit API (Check Android Wear Sensor List)

In this poster, I will introduce the setting for developing Android Wear APP and check the list of sensor list in the LG G Watch R (any android wear fine). 

/* You don't need it if you don't use Google fit API To use the Google Fit for Android, you need an OAuth 2.0 client ID for Android applications. Follow the link (OAuth 2.0) to obtain the OAuth 2.0 client ID. 
*/
I use Android Studio to develop Android wear. I use LG G Watch R for android wear.

Create New Project:

And click "next" -> select "Empty Activity" -> "Next"->"Next" -> select "Always On Wear Activity"-> "Next" -> "Finish"


And Permissions in AndroidManifest.xml under mobile and in AndroidManifest.xml under wear like: 

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

   package="com.example.lee.helloworld">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.BODY_SENSORS" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <application

In build.gradle (Module:mobile, Module:wear) add :
// you don't need it if you don't use Google fit API

compile 'com.google.android.gms:play-services-fitness:9.8.0'

My LG G Watch R's android version is 2.0.0. You can check on your android wear device by( setting -> System -> About -> version) So, I set the compile like:

compile 'com.google.android.support:wearable:2.0.0'

*If there is error in the line, plz click (Alt+ Enter) and select "Disable Inspection" *

In build.gradle(Project: Helloworld), add maven :

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"        }
    }
}

Now, we are ready to program our Android wear APP.

In this poster, I only make codes in the "MainActivity" under "wear".

SensorManager mSensorManager;

   @Override    protected void onCreate(Bundle savedInstanceState) {
//Default Code
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setAmbientEnabled();

        mContainerView = (BoxInsetLayout) findViewById(R.id.container);
        mTextView = (TextView) findViewById(R.id.text);
        mClockView = (TextView) findViewById(R.id.clock);

// Get the Sensor Service using SensorManager
        mSensorManager = ((SensorManager) getSystemService(SENSOR_SERVICE));
//Get Sensor List
        List<Sensor> sensorList = mSensorManager.getSensorList(Sensor.TYPE_ALL);

//  Check Sensor list and display in TextView on your android wear.       
        for(Sensor s: sensorList){
            mTextView.setText(mTextView.getText()+s.getName());
        }

And, click "Run" or Shift+F10 for running your app on Android Wear.
