# OpenGApps


GENYMOBILE SAS assumes no liability whatsoever resulting from the download, install and use of Google Play Services within your virtual devices. You are solely responsible for the use and assume all liability related thereto. Moreover, GENYMOBILE SAS disclaims any warranties of any kind, either express or implied, including, without limitation, implied warranties of merchantability, or fitness for a particular purpose regarding the compatibility of the Open GApps packages with any version of Genymotion. In no event shall GENYMOBILE SAS or its affiliates, or their respective officers, directors, employees, or agents be liable with respect to your download or use of the Google Play Services and you release GENYMOBILE SAS from any liability related thereto. You agree to defend, indemnify and hold harmless GENYMOBILE SAS for any claims or costs related to your use or download of the Google Play Services.

The application you are developing or testing may require an interaction with Google Play Services (e.g.: in-app purchasing, advertising, etc.). The Open GApps widget allows you to install a minimum package of those services, also containing an application store.


Your virtual device must run Android 4.4 and above.


If you wish to install applications with native ARM code from Google Play Store, you have to install the ARM translation tool before the OpenGApps package (see Deploying an application - Applications with ARM code).

# Standard method

To install the OpenGApps package:

  1. Click OpenGApps. At the end of the installation, you are redirected to the OpenGApps website.
  2. Reboot the virtual device when prompted.
  3. (Optional) Open the Play Store and configure your account.

# Alternative method from the OpenGApps website

You can install OpenGApps directly from their website.


Using this method may not work since opengapps.org regularly update their package and may introduce unforeseen bugs.
We recommend using the Standard method instead.

# Remote control

With the Remote control widget Remote control widget button, you can take control of a virtual device from a physical device (any phone or tablet running Android version 2.2/API level 8/Froyo or above). This widget works with a specific Android application that runs on the physical device and forwards touch inputs and accelerometer events to Genymotion Desktop. As a result, you can test your application as if you were holding a device in your hands.

The Remote control widget requires to have ADB installed on your computer. For more information, please refer to section ADB

To use the Remote control widget:

  1. Connect your physical device either by wire or with Wi-Fi. To connect with Wi-Fi, your physical device must support ADB over network. If so:
    1. On your physical device, go to Menu → System settings → Developer options.


      If you have not unlocked this menu yet, go to Menu → System settings → About and click several times on Build number until you get a message meaning that Developer options are now available.

    2. Check Android debugging and then ADB over network.
    3. Connect your physical device to the Wi-Fi and retrieve its IP address from the Wi-Fi menu.
    4. Open a command prompt and enter <path to ADB>\connect <IP>.
  2. Click Remote control widget button.
  3. Activate the widget by clicking On. Genymotion Desktop tries to detect any connected Android device.
  4. Select your device from the Available devices drop-down list and click Start.


    If the device is connected to ADB and not visible in the list, restart the widget.

  5. Check the desired options:
    • Enable preview: enables previewing your Genymotion Desktop screen on your physical device.
    • Enable touch screen: allows your physical device to send touch events to Genymotion Desktop.
    • Enable accelerometer: allows your physical device to send accelerometer events to Genymotion Desktop.

The Remote control widget automatically stops when you disconnect your device.

# Identifiers

The Identifiers widget ID widget shows Device ID and Android ID numbers. You can view and edit these values at any time, without having to reboot your virtual device.

# Android ID

An Android ID is a 64-bit number randomly generated when the user first sets up the device. It remains the same for the whole lifetime of the user's device. Android 4.2.2 and greater versions support multiple user accounts, each one having a unique Android ID. When clicking Random button, a random Android identifier is generated. Valid Android ID numbers are 16-hexadecimal digits long.


You are not allowed to set an empty Android ID.


On Android 8.0 and above, the Android ID has a different value for each application on the device. This is not the case in Genymotion: the Android ID remains the same for all applications.

# Device ID / IMEI / MEID

By default, a new virtual device is deployed with the default device ID number 000000000000000. When clicking Random button, a random identifier is generated. As IMEI or MEID numbers are used as device ID, Genymotion Desktop generates numbers compliant with the GSM 02.16 standard and the 3GPP2 specification (14 digits or hexadecimal digits + a checksum digit). Valid characters for setting device ID/IMEI/MEID are:

  • lower-case and upper-case letters [a-z, A-Z]
  • digits [0-9]
  • dots [ . ], dashes [ - ] and underscores [ _ ]

# Disk I/O

The Disk I/O widget allows you to emulate devices with slow internal storage. It can be very handy if your app requires reading large amount of data from the disk such as gallery apps that load locally stored images or games that load large assets.

To simulate high or poor disk performance:

  1. Click Disk IO.
  2. From Profile, select a type of device:
    • High-end device: Read speed limit 200MiB per second.
    • Mid-range device: Read speed limit 100MiB per second.
    • Low-end device: Read speed limit 50MiB per second.
    • Custom device: enter the read speed limit you wish to emulate in MiB.
  3. Click Update.


When switching from a device profile to another, the disk cache is automatically cleared. You can force clearing the cache by clicking Clear Cache.

# Network

The Network widget Network widget button allows you to test how your application reacts with different network quality and performance types.

To use the Network widget:

  1. Click Network widget button.

  2. Activate the network simulation by clicking On.

  3. Select a network profile from the Profile drop-down list.


    When activating the widget for the first time, the profile network is automatically set to Wifi . It then takes the last network profile used.

  3. Click Send message.

The text message is displayed in the virtual device via a notification and can also be read in the Messaging application.

# App Sharing

The App sharing feature allows you to share an application with other users via Genymotion Cloud SaaS so they can have access to the application within a web browser. As the shared application is being made accessible via a virtual machine running in Genymotion Cloud SaaS, designers, sales representatives or any stakeholders not having Genymotion Desktop Software installed on their workstation are able to see the application being developed or tested in order to give their feedback.

To share an application, you must have previously installed it in a virtual device of Genymotion Desktop. Please refer to Deploying an Application for details.


  1. From your virtual device, click App Sharing.
  2. In Users, enter the e-mail addresses of the users with whom you wish to share the application.
  3. (Optional) In the Message field, add the message of your choice to give information to the users about the purpose of the shared application.
  4. Click Share.

This uploads the application and makes it available to the users you have specified. In the meantime, a notification e-mail is sent to them. They can access the shared application via that e-mail or by signing in directly to Genymotion Cloud SaaS.


An application shared from Genymotion Desktop software to multiple users is not shared among all receivers but instead cloned individually into virtual devices with said application running in Genymotion Cloud SaaS for each one of the receivers.

# Sound Control
