In Android, you can use PackageManager , hasSystemFeature() method to check if a device has camera, gps or other features.

See full example of using PackageManager in an activity class.

package com.mkyong.android;
 
import android.app.Activity;
import android.content.Context;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.util.Log;
 
public class FlashLightActivity extends Activity {
 
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  //setContentView(R.layout.main);
 
  Context context = this;
  PackageManager packageManager = context.getPackageManager();
 
  // if device support camera?
  if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
   //yes
   Log.i("camera", "This device has camera!");
  }else{
   //no
   Log.i("camera", "This device has no camera!");
