18 // Fixes for various things that go wrong between Android versions.
19 // By convention this should be the very first include: it tweaks some
20 // flags that affect the processing of the system headers.
21 //
22 // Code that needs to cope with platform changes should use the
23 // VSOC_PLATFORM_SDK_BEFORE and VSOC_PLATFORM_SDK_AFTER macros below.
24 // It's fine to provide declarations for broadly used things in this file
25 // if that's easier.
26 //
27 // To use this header add $(VSOC_VERSION_CFLAGS) to the LOCAL_CFLAGS
28 // in the corresponding Android.mk. There is an error check to catch
29 // cases where this wasn't done.
30 //
31 // Code should not examine the SDK_PLATFORM_VERSION, and generally shouldn't
32 // look at the VSOC_PLATFORM_SDK_* values. While these currently track
33 // PLATFORM_SDK_VERSION, that's an implementation detail that will probably
34 // change: Android will eventually break things without bumping
35 // PLATFORM_SDK_VERSION.
36 //
37 // This is also why there is no SDK_PLATFORM_VERSION_IS(). Convert these
38 // statements into BEFORE and/or AFTER.
39 //
40 // To check for master/AOSP use VSOC_PLATFORM_VERSION_AFTER(LAST_SHIPPED)
