如果device不支持某种sensor,可以在android/frameworks/base/core/java/android/hardware/SystemSensorManager.java里将其disabled掉。以disable proximity sensor为例。

public SystemSensorManager(Context context, Looper mainLooper) {synchronized(sLock) {if (!sNativeClassInited) {sNativeClassInited = true;nativeClassInit();}}mMainLooper = mainLooper;mTargetSdkLevel = context.getApplicationInfo().targetSdkVersion;mContext = context;mNativeInstance = nativeCreate(context.getOpPackageName());// initialize the sensor listfor (int index = 0;;++index) {Sensor sensor = new Sensor();if (!nativeGetSensorAtIndex(mNativeInstance, sensor, index)) break; //disable p_sensor solution: Remove proximity sensor from sensor list.if ((sensor != null) && sensor.getType() == Sensor.TYPE_PROXIMITY){Log.i(TAG,"skip proximity sensor");continue;}mFullSensorsList.add(sensor);mHandleToSensor.put(sensor.getHandle(), sensor);}}

就是将p_sensor 从mFullSensorsList中移出。这一步基本上已经work了(SensorManager#getSensorList(8)得不到p_sensor的讯息)，但是如果你的code还需要通过CTS测试，那么最好在android/frameworks/base/services/core/java/com/android/server/pm/PackageManagerService.java的hasSystemFeature方法里做remove proximity sensor feature

public boolean hasSystemFeature(String name, int version) {// allow instant applicationssynchronized (mAvailableFeatures) {final FeatureInfo feat = mAvailableFeatures.get(name);if (feat == null) {return false;} else {//remove proximity sensor featureif(name.equals("android.hardware.sensor.proximity")){Log.w(TAG, "skip standard  proximity sensor");return false;}return feat.version >= version;}}}

这样一来PackageManager#hasSystemFeature(android.hardware.sensor.proximity) return false。

可用命令adb shell pm list features来检查device都support 那些功能。

或者尝试删除frameworks\native\data\etc下相关的配置文件
