MonkeyDevice

A monkeyrunner class that represents a device or emulator accessible by the workstation running monkeyrunner.

This class is used to control an Android device or emulator. The methods send UI events, retrieve information, install and remove applications, and run applications.

You normally do not have to create an instance of MonkeyDevice. Instead, you use MonkeyRunner.waitForConnection() to create a new object from a connection to a device or emulator. For example, instead of using:

newdevice = MonkeyDevice()

you would use:

newdevice = MonkeyRunner.waitForConnection()

Summary

Constants
string DOWN Use this with the type argument of press() or touch() to send a DOWN event.
string UP Use this with the type argument of press() or touch() to send an UP event.
string DOWN_AND_UP Use this with the type argument of press() or touch() to send a DOWN event immediately followed by an UP event.
Methods
void broadcastIntent (string uri, string action, string data, string mimetype, iterable categories dictionary extras, component component, iterable flags)
Broadcasts an Intent to this device, as if the Intent were coming from an application.
void drag (tuple start, tuple end, float duration, integer steps)
Simulates a drag gesture (touch, hold, and move) on this device's screen.
object getProperty (string key)
Given the name of a system environment variable, returns its value for this device. The available variable names are listed in the detailed description of this method.
object getSystemProperty (string key)
. The API equivalent of adb shell getprop <key>. This is provided for use by platform developers.

Public Methods

void broadcastIntent ( string uri, string action, string data, string mimetype, iterable categories dictionary extras, component component, iterable flags)

Broadcasts an Intent to this device, as if the Intent were coming from an application. See Intent for more information about the arguments.

Arguments
uri The URI for the Intent. (see Intent.setData()).
action The action for this Intent (see Intent.setAction()).
data The data URI for this Intent (see Intent.setData()).
mimetype The MIME type for the Intent (see Intent.setType()).
categories An iterable data structure containing strings that define categories for this Intent (see Intent.addCategory()).
extras A dictionary of extra data for this Intent (see Intent.putExtra() for an example).

The key for each dictionary item should be a string. The item's value can be any simple or structured data type.

component The component for this Intent (see ComponentName). Using this argument will direct the Intent to a specific class within a specific Android package.
flags An iterable data structure containing flags that control how the Intent is handled (see Intent.setFlags()).

void drag ( tuple start, tuple end, float duration, integer steps)

Simulates a drag gesture (touch, hold, and move) on this device's screen.

Arguments
start The starting point of the drag gesture, in the form of a tuple (x,y) where x and y are integers.
end The end point of the drag gesture, in the form of a tuple (x,y) where x and y are integers.
duration The duration of the drag gesture in seconds. The default is 1.0 seconds.
steps The number of steps to take when interpolating points. The default is 10.

object getProperty (string key)

Given the name of a system environment variable, returns its value for this device.

Arguments
key The name of the system environment variable. The available variable names are listed in Table 1. Property variable names at the end of this topic.
Returns
  • The value of the variable. The data format varies according to the variable requested.

object getSystemProperty (string key)

Synonym for getProperty().

Arguments
key The name of the system environment variable. The available variable names are listed in Table 1. Property Variable Names.
Returns
  • The value of the variable. The data format varies according to the variable requested.

void installPackage (string path)

Installs the Android application or test package contained in packageFile onto this device. If the application or test package is already installed, it is replaced.

Arguments
path The fully-qualified path and filename of the .apk file to install.

dictionary instrument ( string className, dictionary args)

Runs the specified component with Android instrumentation, and returns the results in a dictionary whose exact format is dictated by the component being run. The component must already be present on this device.

Use this method to start a test case that uses one of Android's test case classes. See Testing Fundamentals to learn more about unit testing with the Android testing framework.

Arguments
className The name of an Android component that is already installed on this device, in the standard form packagename/classname, where packagename is the Android package name of a .apk file on this device, and classname is the class name of an Android component (Activity, ContentProvider, Service, or BroadcastReceiver) in that file. Both packagename and classname must be fully qualified. See ComponentName for more details.
args A dictionary containing flags and their values. These are passed to the component as it is started. If the flag does not take a value, set its dictionary value to an empty string.
Returns
  • A dictionary containing the component's output. The contents of the dictionary are defined by the component itself.

    If you use InstrumentationTestRunner as the class name in the componentName argument, then the result dictionary contains the single key "stream". The value of "stream" is a string containing the test output, as if InstrumentationTestRunner was run from the command line. The format of this output is described in Testing in Other IDEs.

void press (string name, integer type)

Sends the key event specified by type to the key specified by keycode.

Arguments
name The name of the keycode to send. See KeyEvent for a list of keycode names. Use the keycode name, not its integer value.
