public abstract class MapActivity
extends android.app.Activity

Base class with code to manage the boring necessities of any activity that displays a MapView. Activity responsibilities include:

• Activity lifecycle management
• Setup and teardown of services behind a MapView

A subclass should create its own MapView in onCreate(android.os.Bundle), either with the MapView constructor (then add it to a layout View with ViewGroup.addView(View)) or leave the construction (and layout) up to inflation from the layout XML.

This is not a standard package in the Android library. In order to use it, you must add the following XML element, as a child of the application element, in your AndroidManifest.xml file:

<uses-library android:name="com.google.android.maps" />

Only one MapActivity is supported per process. Multiple MapActivities running simultaneously are likely to interfere in unexpected and undesired ways.

public MapActivity()

Method Detail

onCreate

protected void onCreate(android.os.Bundle icicle)

Here we initialize static factories, create the map object and the traffic service, but do not begin any threads. The subclass should create (or inflate) its MapView object after calling through to super.onCreate().

Overrides:

onCreate in class android.app.Activity

onNewIntent

public void onNewIntent(android.content.Intent newIntent)

Overrides:

onNewIntent in class android.app.Activity

onResume

protected void onResume()

Here we tell the map to "predraw", which front-loads fetching and decoding, so that the first draw will appear more "atomic". Start our threads: the traffic service and resume the MapView which will register for the updates.

Overrides:

onResume in class android.app.Activity

onPause

protected void onPause()

Pauses threads such as the traffic service, because we don't want it running forever in the background. Also saves preferences.

Overrides:

onPause in class android.app.Activity

onDestroy

protected void onDestroy()

Stops all our threads and frees all our resources.

Overrides:

onDestroy in class android.app.Activity

isRouteDisplayed

protected abstract boolean isRouteDisplayed()

For accounting purposes, the server needs to know whether or not you are currently displaying any kind of route information, such as a set of driving directions. Subclasses must implement this method to truthfully report this information, or be in violation of our terms of use. TODO: provide link

Returns:

True if route information is displayed; false otherwise.

isLocationDisplayed

protected boolean isLocationDisplayed()

For accounting purposes, the server needs to know whether or not you are currently displaying any kind of sensor-based estimation of the device's current location. By default, this method returns true if a subclass of MyLocationOverlay has been added through MapView.getOverlays() and has location enabled; however, subclasses which display the location by any other means must override this method to truthfully report this information, or be in violation of our terms of use. TODO: provide link

Returns:

True if user location information is displayed; false otherwise.

onGetMapDataSource

protected int onGetMapDataSource()

This method will be called once, during onCreate(Bundle), and its return-value will determine the map data source that the MapView will display for the lifetime of this Activity. The default value is undefined and may change from system to system. If your activity requires a specific map data source, you should override this method to return it. If an unrecognized or unsupported value is returned, the system default will be used.
