On mobile devices, Java ME provides some subset of "standard" APIs (JSR) and possibly some vendor specific APIs (in addition to whatever is defined in the configuration (CDC or CLDC) and the profile (MIDP or Personal Profile). This article outlines the main APIs on Nokia devices.

You have to be sure that the device the MIDlet is running on has the API before using it. You can check over platform information, for example for Series 40 or Symbian see Java ME API support on Nokia devices.

API Groups

There are two standards defined to reduce fragmentation, grouping many of the APIs in one platform name:

Non standard APIs

Many APIs are specific to some vendor or operator. In this category, we can find:

Standard APIs

There are 82 JSRs defined in JCP about Java ME. Many of them are still in draft and will be available in future devices and some were deprecated. The list of Java ME JSRs is http://jcp.org/en/jsr/tech?listBy=1&listByType=platform

The most common additional APIs found on mobile devices are:
