still here in r14

I believe there is an error in the bug description.
the Expected results would be a return value of false.
but what one gets is a true value instead.

it seems to affect all android versions.

interesting fact:
the "Camera Support" property (hw.camera) defaults to 'no'.
but yet every AVD I tried so far has a camera app and it is even working quite well.
just so as one would expect if the AVD would have hw.camera=yes.

I tried AVDs with explicitly turning off an on the camera support but they behaved exactly the same way.

this is quit frustrating if you want to write an app, that could optionally use a camera but also works on devices without a camera.

ok, there are few devices without camera but it would be nice to test what happens if the app is used on such a device.

To completely turn off camera emulation start the emulator with '-webcam off', and '-fake-camera off' options. In this case there will be no camera devices reported.

thanks, but could you be a little more verbose?

I usually start the emulators from the eclipse gui.
I tried:
android-sdk-linux_x86/tools/emulator-arm -avd nocam -qemu -webcam off -fake-camera off
and
android-sdk-linux_x86/tools/emulator-arm -avd nocam -webcam off -fake-camera off
but the options seem to be unknown either way.
thes are not listed in the -help

(got the command lines from the process list ;-) )

also there, there is no sign of the options:
http://developer.android.com/guide/developing/tools/emulator.html

The correct line is the second one. If emulator -help doesn't list -webcam option, it's not the r14 emulator.

you were right. maybe something went wrong while updating. I deleted and reinstalled everything. now, the options work.

however.. it does not change the behavior of the code mentioned above. (avd with android 2.3.3) even the camera works.
on the 4.0  avd, the camera crashes if used with the '-webcam off', and '-fake-camera off' options. so, the options have some effect but just not as expected.

there might be a bug in my cam detection code, but its pretty much the same as the example above. maybe I'll just hard code a 'false' there to have a look at the behavior of the app on a device with no camera.

Seems there is already a solution in comment #3 by means of different use, but this is what the symptoms were for me:

run "adb -e shell pm list features", and get:

feature:reqGlEsVersion=0x0
feature:android.hardware.camera
feature:android.hardware.camera.autofocus

I wouldn't expect those last two lines.

Can this please be fixed? Testing for the Amazon Kindle is made a lot harder by this not really working and having to use the command line launch of the emulator for testing this.

I am using r16 btw...

Vladimir's suggestions did NOT work ("emulator-arm -avd 2.2-no-camera -webcam off -fake-camera off")

Not sure how you can flag this as released. I just tested it with r17 of the sdk and a brand new avd off 4.0.3. In the avd manager I set CameraSuport to No and number of emulated web cameras to 0 (which should turn off the camera according to the inline documentation).

Lo and behold.. it still does not work. While the command line invocation might work this is not a acceptable solution imho..

I'm seeing this in r20

I'm having this exact issue in Android Studio 1.3.2 Using the following emulator


Name: Nexus_5_No_Features_API_23

Camera detection code:
        boolean hasCamera = getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY);
        Log.i("myTag", String.valueOf(hasCamera));
        return hasCamera();

When logged, the value of hasCamera is true. With this emulator that code is expected to return false.

I was able to get around this limitation by disabling the camera app in the Emulator's Settings:

Settings ->  Apps -> All -> Camera -> Disable

It still does not work!

It is still broken, the emulator does not respect the "no camera" setting. If I create an emulated device and set all cameras to none, PackageManager.hasSystemFeature( FEATURE_CAMERA_ANY ) returns true and android.hardware.Camera.getNumberOfCameras() returns > 0. This really should not be a bug that takes 7 years to fix.

Now we are at 10 years, actually.

Shout-out to the OG Android devs who have been watching this ticket for a decade. Hope you are all doing well!

Still broken in Android 10. The tutorial below tells us that this is the correct method, if it doesn't work why hasn't the tutorial been updated?
