Android接近传感器问题仅在Samsung设备中 [英] Android proximity sensor issue only in Samsung devices
问题描述
避免出现问题的特定方案:
三星设备中活动"的行为有所不同，其方式是每次检测到变化时(接近)都会导致在三星设备上仅调用onPause()/onResume().
Specific scenario to avoid problems:
Behaviour for Activity in Samsung devices was different in the manner that every time there was a change detected, for proximity, it resulted in a call to onPause()/onResume() ONLY on SAMSUNG devices.
我正在清理onPause()中的接近传感器，这导致了三星设备独有的行为.
I was clearing the proximity sensors in onPause() which resulted in a behaviour unique to Samsung devices.
希望这可以为面临此问题的任何人节省一些时间.我从onPause()中删除了清除邻近侦听器的调用，现在它可以在提到的设备上按预期工作.
Hope this saves some time for anybody who's facing this. I removed the call of clearing proximity listeners from onPause() and now it works as expected on the mentioned devices.
更新:
UPDATE:
下面提到的不是唯一的问题，接近传感器并非始终以这种方式运行.另一个问题是l-o-c:
What is mentioned below is not the only issue, the proximity sensor does not consistently behave in that manner. The other issue is a l-o-c:
if (!mWakeLock.isHeld()) mWakeLock.acquire();
随机地，if()对于所提及的设备返回false，因此mWakeLock.acquire()并不总是被调用.
Randomly, the if() returns false for the mentioned devices hence mWakeLock.acquire() isn't always called.
可能相关的信息:
mWakeLock = mPowerManager.newWakeLock(field, getLocalClassName());
其中
field = PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK or 32
我的接近传感器代码仅在上不能正确使用
1.三星GT-I9082 Android 4.2.2(API 17)[duos grand]
2.三星SM-G925I Android 5.1.1(API 22)[s6 edge]
My proximity sensor code works incorrectly only on
1. Samsung GT-I9082 Android 4.2.2 (API 17) [duos grand]
2. Samsung SM-G925I Android 5.1.1 (API 22) [s6 edge]
代码:
sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
sensor = sensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
...new SensorEventListener() {
@Override
public void onSensorChanged(SensorEvent event) {
if (event.sensor.getType() == Sensor.TYPE_PROXIMITY) {
if (event.values[0] <= 5) { //Sleep
turnOffScreen();
} else { //Wake
turnOnScreen();
}...
// registering listener with SensorManager.SENSOR_DELAY_NORMAL);
问题:
即使我们不断将手放在手机上几秒钟，两个设备上的接近传感器返回的记录值也会发生波动. 10-15而不移动它.
喜欢:
三星6 edge-
the problem:
Logged values returned by proximity sensor on both devices fluctuate, even while we place a hand over the phones constantly for a few seconds; 10-15 without moving it.
Like:

还有哪些其他方法或排列组合可以成功且准确地用于解决此问题?
What are there other ways or permutation-combinations which can be applied successfully and accurately to solve this issue?
是因为传感器不同吗? GP2A接近传感器和APDS-9930/QPDS-T930接近&轻吗?
Is it because of different sensors; GP2A Proximity Sensor and APDS-9930/QPDS-T930 Proximity & Light ?
已经花了很多时间..徒然

推荐答案
因此，这是Samsung设备的已注册问题，这是一组页面，可以帮助面临此问题的任何人:
So turns out this is a registered issue with Samsung devices, here is a collection of pages which could help anybody facing this:
-
使用 onWindowFocusChanged .这对我来说很有意义，并且与onPause()有关的实现在遵循该实现时也很成功.
来源和解释:活动-onpause-to-handle-focus
是什么帮助了我:而不是在onPause()中；
Use onWindowFocusChanged. This made sense to me and my implementation related to onPause() was successful on following the same.
Source and Explanation: activity-onpause-to-handle-focus
What helped me: instead of inonPause();
@Override 公共无效onWindowFocusChanged(boolean hasFocus){ super.onWindowFocusChanged(hasFocus); if(！hasFocus){ clearProximityListeners(); } }
@Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); if(!hasFocus){ clearProximityListeners(); } }
问题74464:Activity#onPause调用时不带Activity#onResume，还是Context#registerReceiver失败
