3.7. Runtime Compatibility
Device implementations:
-
[C-0-1] MUST support the full Dalvik Executable (DEX) format and Dalvik bytecode specification and semantics.
-
[C-0-2] MUST configure Dalvik runtimes to allocate memory in accordance with the upstream Android platform, and as specified by the following table. (See section 7.1.1 for screen size and screen density definitions.)
-
SHOULD use Android RunTime (ART), the reference upstream implementation of the Dalvik Executable Format, and the reference implementation’s package management system.
-
SHOULD run fuzz tests under various modes of execution and target architectures to assure the stability of the runtime. Refer to JFuzz and DexFuzz in the Android Open Source Project website.
Note that memory values specified below are considered minimum values and device implementations MAY allocate more memory per application.
