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().
