PROXIMITY_SCREEN_OFF_WAKE_LOCK无法与三星配合使用 [英] PROXIMITY_SCREEN_OFF_WAKE_LOCK not working with Samsung

问题描述

我正在使用接近传感器，而android中的webRtc调用使用设备传感器来打开/关闭屏幕.它可以在大多数设备上正常运行，但不能在三星设备上运行.当Sensor关闭屏幕时，将调用该活动的onStop().以下是我正在使用的代码:

I am using the Proximity Sensor while webRtc call in android to turn screen on/off using device sensor. It is working perfectly in most of the devices but not in Samsung. When Sensor turns the screen off onStop() of the activity is called. Following is the code I am using :

@Override
    public void onSensorChanged(SensorEvent sensorEvent) {
        if (sensorEvent.sensor.getType() == Sensor.TYPE_PROXIMITY) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                if (mWakeLock != null) {
                    mWakeLock.release(1);
                    mWakeLock = null;
                }
                if (sensorEvent.values[0] >= -SENSOR_SENSITIVITY && sensorEvent.values[0] <= SENSOR_SENSITIVITY) {
                    mWakeLock = mPowerManager.newWakeLock(PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK, "tag");
                    mWakeLock.acquire();
                } else {
                    //far
                    mWakeLock = mPowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "tag");
                    mWakeLock.acquire();
                }
            }
        }
    }

推荐答案

尽量不要直接使用SensorManager.它帮助我使用了三星S10e.

Try not to use SensorManager directly. It helped me with the Samsung S10e.

class ProximityMgr(context: Context) {
    private val powerManager: PowerManager = context.getSystemService()!!
    private val wakeLock: PowerManager.WakeLock

    init {
        wakeLock = powerManager.newWakeLock(
                PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK, 
                "lock:proximity_screen_off")
    }

    fun acquire() {
        if (powerManager.isWakeLockLevelSupported(PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK)) {
            if (wakeLock.isHeld) {
                wakeLock.release()
            }
            wakeLock.acquire(WAKE_LOCK_TIMEOUT_MS)
        } else {
            Log.w(TAG, "not supported")
        }
    }

    fun release() {
        if (wakeLock.isHeld)
            wakeLock.release()
    }

    companion object {
        private const val TAG = "ProximitySensor"
        private const val WAKE_LOCK_TIMEOUT_MS: Long = 2 * 3600 * 1000
    }
}
