安卓設備如何測試攝像頭

A. 安卓手機下載什麼可以檢測有沒有攝像頭

360安全衛士、網路衛士、檢測攝像頭APP

B. 檢查android是否具有攝像頭

import android.hardware.Camera;
import android.hardware.Camera.CameraInfo;
import android.os.Build;
public class CameraUtils {
/**
* 檢測是否有前置攝像頭
* @return
*/
public static boolean hasFrontFacingCamera() {
final int CAMERA_FACING_BACK = 1;
return checkCameraFacing(CAMERA_FACING_BACK);
}

/**
* 檢測是否有後置攝像頭
* @return
*/
public static boolean hasBackFacingCamera() {
final int CAMERA_FACING_BACK = 0;
return checkCameraFacing(CAMERA_FACING_BACK);
}

private static boolean checkCameraFacing(final int facing) {
if (getSdkVersion() < Build.VERSION_CODES.GINGERBREAD) {
return false;
}
final int cameraCount = Camera.getNumberOfCameras();
CameraInfo info = new CameraInfo();
for (int i = 0; i < cameraCount; i++) {
Camera.getCameraInfo(i, info);
if (facing == info.facing) {
return true;
}
}
return false;
}

public static int getSdkVersion() {
return android.os.Build.VERSION.SDK_INT;
}
}
