At times, we make apps which use camera feature but that app can also be used on non camera devices for other features. There we have to apply a check on using the camera feature, that is as follows:
- PackageManager packageManager = activity.getPackageManager();
- //checking if device has camera
- if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
- //yes, perform the further camera code here.
- Toast.makeText(activity, "The device has camera.", Toast.LENGTH_SHORT).show();
- }else{
- //camera not found.
- Toast.makeText(activity, "The device has no camera.", Toast.LENGTH_SHORT).show();
- }
PackageManager packageManager = activity.getPackageManager();
//checking if device has camera
if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
//yes, perform the further camera code here.
Toast.makeText(activity, "The device has camera.", Toast.LENGTH_SHORT).show();
}else{
//camera not found.
Toast.makeText(activity, "The device has no camera.", Toast.LENGTH_SHORT).show();
}
PackageManager class used above can also be used to detect other features like wifi, bluetooth, flash, autofocus, gps, network etc.
