Google Android Compatibility Definition: Android 1.6 - Manual (Page 15)

• Monkey [ Resources , 23]
Device implementations MUST include the Monkey framework, and make it available for
applications to use.
8. Hardware Compatibility
Android is intended to support device implementers creating innovative form factors and configurations.
At the same time Android developers expect certain hardware, sensors and APIs across all Android
device. This section lists the hardware features that all Android 1.6 compatible devices must support. In
Android 1.6, the majority of hardware features (such as WiFi, compass, and accelerometer) are required.
If a device includes a particular hardware component that has a corresponding API for third-party
developers, the device implementation MUST implement that API as defined in the Android SDK
documentation.
8.1. Display
Android 1.6 includes facilities that perform certain automatic scaling and transformation operations under
some circumstances, to ensure that third-party applications run reasonably well on hardware
configurations for which they were not necessarily explicitly designed [
Resources , 24]. Devices MUST
properly implement these behaviors, as detailed in this section.
8.1.1. Standard Display Configurations
This table lists the standard screen configurations considered compatible with Android:
Screen Type Width (Pixels) Height (Pixels)
Diagonal
Length Range
(inches)
Screen Size
Group Screen Density
Group
QVGA 240 320 2.6 - 3.0 Small Low
WQVGA 240 400 3.2 - 3.5 Normal Low
FWQVGA 240 432 3.5 - 3.8 Normal Low
HVGA 320 480 3.0 - 3.5 Normal Medium
WVGA 480 800 3.3 - 4.0 Normal High
FWVGA 480 854 3.5 - 4.0 Normal High
WVGA 480 800 4.8 - 5.5 Large Medium
FWVGA 480 854 5.0 - 5.8 Large Medium
Device implementations corresponding to one of the standard configurations above MUST be configured
to report the indicated screen size to applications via the android.content.res.Configuration [
Resources ,
25] class.
Some .apk packages have manifests that do not identify them as supporting a specific density range.
When running such applications, the following constraints apply:
