多媒体与传感器

图片加载（Glide）

Glide.with(context).load(url).into(imageView);

音频播放（MediaPlayer）

MediaPlayer player = MediaPlayer.create(context, R.raw.music);
player.start();

相机调用

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);

传感器使用（加速度）

SensorManager sm = (SensorManager) getSystemService(SENSOR_SERVICE);
Sensor sensor = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
SensorEventListener listener = new SensorEventListener() {
    @Override
    public void onSensorChanged(SensorEvent event) {
        float x = event.values[0];
    }
    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {}
};
sm.registerListener(listener, sensor, SensorManager.SENSOR_DELAY_NORMAL);
