CTS sensor错误--shows sensors [xxxx xxxx] expected: but was:

在跑cts的时候碰到有一个问题，现在记录如下：


错误声明：
junit.framework.AssertionFailedError: PackageManager#hasSystemFeature(android.hardware.sensor.compass) returns false but SensorManager#getSensorList(2) shows sensors [xxxx 3-axis Magnetic Field sensor] expected:<false> but was:<true>
at android.app.cts.SystemFeaturesTest.assertFeatureForSensor(SystemFeaturesTest.java:300)


解决办法：
增加文件：android.hardware.sensor.compass.xml

然后在跑cts发现此fail已经可以pass了。


Have Fun！
