# Returns true if camera intent is presented to the user.
# Depends on camera existence (YesYouCam.camera_exists?)
YesYouCam.capture_photoOn Take a Photo Completion - Get Photo
# called in BluePotion when the photo has been taken (or any activity is completed actually)
# If you're not using a PMActivity you should capture the onActivityResult method.
def activity_result(request_code, result_code, data)
# Verify this activity was for us!
if (request_code == YesYouCam::CAPTURE_IMAGE_RC)
if (result_code == YesYouCam::OK) # OR Android::App::Activity::RESULT_OK
# Photo success!
mp "Full sized photo located at #{YesYouCam.photo_path}"
# now you can do find!(:some_image_view).imageBitmap = YesYouCam.bmp_data
else
# Photo failed or was cancelled
app.toast "No Photo"
end
end
endWant a PNG?
# Did you need a PNG instead of a JPG?
YesYouCam.photo_path # Some JPG path
YesYouCam.pic_to_png
YesYouCam.photo_path # Some new PNG pathNeed the photo discoverable by Photo Libraries and other Apps?
# Run this and the current photo (YesYouCam.photo_path) will be
# added to the user's Photo Gallery, and accessible by all apps.
YesYouCam.add_to_galleryLet the user select a photo from their library?
# Fire off a photo choose request

endInstallation
Add this line to your application's Gemfile:
gem 'yesyoucam'
And then execute:
$ bundle
Now make sure your Rakefile has camera permissions and features needed:
# This gem will try to add permissions, but it's best that you assure they are set!
app.permissions += [:write_external_storage]
# This gem will add this feature, but it's safest for you to also set it!
app.features = ["android.hardware.camera"]
