Emulator Control Panel

Before deploying your application, it is important that you test it in an environment similar to a real device.

You can run the application in the emulator, and test a variety of user scenarios, such as network access, audio input and out, and text messages. You can control the application in the emulator with mouse and keyboard buttons, like if you used an actual device.

During the run, you can use the Emulator Control Panel to inject events for several system options that the actual device provides. For example, by manipulating the optional battery, you can simulate the application in different charge environments.

The emulator controls consist of internal and external parts:

  • The HOME, Volume control and Back buttons, for example, are external parts controlling the device from the outside.

    In the emulator, the external parts are called the emulator control keys and menu.

  • Battery level and screen brightness, for example, are internal parts controlling the device from the inside. In the emulator, the internal parts are called the Emulator Control Panel.

Using the Control Keys and Context Menu

The control keys are visible on the emulator when you start it. To access the context menu, right-click the emulator.

NoteYou can create a custom resolution emulator by using the Emulator Manager CLI, and launch it with the TV and mobile skin. It is not guaranteed that all the applications are correctly shown in the custom resolution.

Control Keys

The following hardware keys are available on the emulator:

  • Menu

    When tapped, it opens a list of options available for the current screen. This button can be used to delete an application on the TV platform.

  • Home

    When long-pressed, the Task switcher application opens as in a real device.

  • Back

    When tapped, the emulator returns to the previous screen.

  • Power

    You can power off the display by tapping the Power key in most general situations. Sometimes, the display does not power off though you tap the Power key. This is to guarantee the operation of a current application, such as the Stopwatch in the Clock application. If you tap the Power or Home key again, the display is powered on.

  • Volume Up and Volume Down (mobile only)

    When tapped, the volume changes accordingly.

  • Arrow keys (TV only)

    When tapped, the cursor or selection moves to the desired direction.

  • OK (TV only)

    When tapped, the item is selected.

 

You can access the context menu by right-clicking the emulator. In the menu, you can select:

  • Emulator name (the top row in the menu)

    The Detailed Info window is displayed, showing the Shortcut Info and VM Info tabs. The Shortcut Info tab lists the emulator keyboard shortcuts and the VM Info tab defines the virtual machine details.

  • In the Battery card, you can set the battery level using the Level slider. You can also connect or disconnect a charger using the Charger switch.
  • In the Ear Jack card, you can add or remove an earjack (headset) device. You can add a 3-wire or 4-wire device.
  • In the USB card, you can connect or disconnect a USB device.
  • In the RSSI card, you can set the RSSI (remote signal strength indicator) information level.
  • In the SDCard card, you can attach or detach an SD card to or from the emulator at runtime. You can attach a 4G, 8G, 16G, or 32G SD card.
    Note The same SD card cannot be attached to multiple emulators at the same time.

Device information set using the control panel is reflected on the indicator bar of the emulator screen.

Providing Location Data

In the Location card, you can provide simulated responses to location data requests:

  • Injecting map markers

    In the Map Image section, right-click the desired map locations and click Inject Markers to send the location data to the emulator.

  • Manually entering location coordinates

    In the Manual section, enter the coordinates and click Inject Location to send the location data to the emulator. The range of the latitude, longitude, altitude, and horizontal accuracy is from -90 to 90, -180 to 180, -300 to 100000, and 0 to 100000, respectively.

  • Loading a GPS log file

    In the Log section, select a pre-logged GPS data file (in NMEA183 format) and click Inject Log to send the location data to the emulator.

Providing NFC Data

In the NFC card, you can test near-field communication (NFC) features.

Note The control panel only sends NFC-related events to the emulator. There is no actual information exchange between the control panel and emulator. Therefore, for information exchange features, such as writing information to an NFC tag, the emulator simply displays a success message.
  • Creating NFC data exchange format (NDEF) messages

    An NDEF message contains 1 or more NDEF records. In the NDEF Message section:

    1. Select the record type name format.
    2. Enter the record type name, ID, and payload.
    3. Click Add.

    You can add multiple NDEF records in the NDEF message.

    Click Edit or Remove to modify or delete a selected record.

  • Attaching and detaching NFC tags

    In the NDEF Tag section:

    1. Select the tag type.
    2. Click the switch to attach or detach the tag.

      If the NDEF record list is not empty, an NDEF message is created using this list and the attach message is sent to the emulator with the NDEF message.

  • Creating a peer-to-peer (P2P) data connection

    In the PEER TO PEER section:

    • To inform the emulator that a new device has been discovered, click P2P Discovered.
    • To send the emulator an NDEF message, click P2P Send.
    • To inform the emulator that a connected device has been detached, click P2P Detached.

Providing Sensor Data

In the control panel, you can model user actions, such as shaking, throwing, and tilting the device, for the emulator instance. In addition, you can simulate a single sensor event on the instance, or send sequences of 3-axis sensor events to the instance.

  • In the Sensor card, you can control the 3-axis sensors. The popup consists of 4 tabs, where you can adjust the acceleration, magnetic, and gyro sensors of the emulator instance. In the GUI tab, you can intuitively adjust various sensor data by using 3D graphics.

    • GUI

      In the GUI tab, you can select an active sensor and move the 3D model of the emulator instance with the 3 axis sliders or the direction buttons (Portrait, Landscape, Reverse Portrait, and Reverse Landscape). The instance monitor displays the acceleration, magnetic, and gyro values.

      To better control the movement, select the With axis check box to see the axes in the emulator image. You can also fix the Y or Z axis by selecting the X/Z or X/Y radio button, respectively. To change the emulator accelerator value in the direction of the movement, select the Move radio button.

    • Acceleration

      In the Acceleration tab, you can control the acceleration of the instance along the coordinate axes. When the emulated device is stationary and vertical in portrait orientation, the acceleration value of the Y axis is 1 g (gravitational acceleration). You can control the acceleration 3-axis values from -2 g to 2 g, using the sliders.

    • Magnetic

      In the Magnetic tab, you can control the magnetic field values of the instance along the coordinate axes. When the emulated device is stationary and vertical in portrait orientation, the Y axis is at true north and the magnetic field strength values are 1, 0, and -10 µT (microtesla). You can control the magnetic field 3-axis values from -2000 µT to 2000 µT, using the sliders.

    • Gyro

      In the Gyro tab, you can control the gyro (rotation angle per second) of the instance along the coordinate axes. You can control the gyro 3-axis values from -573 degrees/s to 573 degrees/s, using the sliders.

    You can simulate a single event on the individual sensor, or use sensor data files to simulate sequences of events on the sensor. A sensor data file consists of predefined events. It is written in ASCII. By loading a data file in the Acceleration, Magnetic, or Gyro tab, you can play a sequence of predefined events. You can also add multiple data files to be played in sequence. The format of each line in the event file is:

    timestamp, x, y, z
    

    When you add the event files and click Start, the predefined events are simulated at their specified relative timestamp. The timestamp unit is 0.01 seconds. Some events can be discarded, if they exceed certain limits of performance, resource, or logic.

  • In the Light card, you can simulate ambient light conditions using the Lux slider. The range of this value is from 0 Lux to 65635 Lux.

    If automatic screen brightness is activated in the device settings, the display changes based on the simulated light value.

  • In the Proximity card, you can set the proximity sensor state to Far or Near.
  • In the Pressure card, you can control the pressure sensor using the hPa slider. The range of this value is from 260 hPa to 1260 hPa (Hectopascals).
  • In the Ultraviolet card, you can control the ultraviolet sensor using the Index slider. The unit is UV index and the range of this value is from 0 to 15.0.
  • In the Heart Rate card, you can control the HRM (Heart Rate Monitor) sensor. You can use the bpm slider to set the heart rate value between 0 and 220 bpm, and the ms slider to set the peak-to-peak time between 0 and 5000 ms (milliseconds).
  • In the Pedometer card, you can simulate user movement with the device by selecting a movement pace:
    • Stop
    • Walk Slowly
    • Walk
    • Run Slowly
    • Run

Providing Telephony Features

In the Telephony card, you can generate incoming calls and messages:

  • Generating incoming calls

    Incoming calls are generated in the Call tab.

    Note A Mobile Termination (MT) call is made from the Emulator Control Panel to the emulator. A Mobile Origination (MO) call is made from the emulator to the Emulator Control Panel using the emulator's phone application.

    To make an MT call:

    1. In the MT Call section, enter the phone number you want to imitate the call from.
    2. Click Connect.
