android 推断是否支持闪光灯

近期在做录制视频功能,在找一些资料时发现 要推断是否支持闪关灯,在这记录下来,怕以后忘记

public static boolean isSupportCameraLedFlash(PackageManager pm) {

if (pm != null) {

FeatureInfo[] features = pm.getSystemAvailableFeatures();

if (features != null) {

for (FeatureInfo f : features) {

if (f != null && PackageManager.FEATURE_CAMERA_FLASH.equals(f.name))

return true;

}

}

}

return false;

}
