Check if device has a camera?

Question

In my app, I\'d like to use the camera, if the device has one. Are there any devices running android that do not have a camera? By including the following into my m

Answer 1

As per Android documentation :

/** Check if this device has a camera */
private boolean checkCameraHardware(Context context) {
    if (context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA)){
        // this device has a camera
        return true;
    } else {
        // no camera on this device
        return false;
    }
}

Refer more about the camera API :

Answer 2

One line solution:

public static boolean hasCamera(Context context) {
    return context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA);
}

Put this method in your Utils.java project class.

Answer 3

As per the documentation, you have to use Package Manager to check if Camera is available on the device or not

In Java:

final boolean isCameraAvailable = getPackageManager().hasSystemFeature(FEATURE_CAMERA);

In Kotlin:

val isCameraAvailable = packageManager.hasSystemFeature(FEATURE_CAMERA)

Answer 4

by following way we can check does device has camera or not.

/** Check if this device has a camera */
    public static boolean checkCameraHardware(Context context) {
        if (context.getPackageManager().hasSystemFeature(
                PackageManager.FEATURE_CAMERA)) 
        {
            return true;
        }
        else if(context.getPackageManager().hasSystemFeature(
                PackageManager.FEATURE_CAMERA_FRONT))
        {
            return true;
        }
        else {
            return false;
        }
    }

Answer 5

I've not tried it, but:

private android.hardware.Camera mCameraDevice;

try {
  mCameraDevice = android.hardware.Camera.open();
} catch (RuntimeException e) {
  Log.e(TAG, "fail to connect Camera", e);
  // Throw exception
}

May be what you need.

This is what I'm using

import android.content.pm.PackageManager;

PackageManager pm = context.getPackageManager();

if (pm.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
}

All sorts of other fun things to test for are available too - the compass, is location available, is there a front facing camera: http://developer.android.com/reference/android/content/pm/PackageManager.html
