      "message": "Introduce new build tool: hiddenapi\n\nNew tool `hiddenapi` iterates over all class members inside given\nDEX files and modifies their access flags if their signatures\nappear on one of two lists - greylist and blacklist - provided as\ntext file inputs. These access flags denote to the runtime that\nthe marked methods/fields should be treated as internal APIs with\nrestricted access.\n\nTwo bits of information are encoded in the DEX access flags. These\nare encoded as unsigned LEB128 values in DEX and so as to not\nincrease the size of the DEX, different modifiers were chosen to\ncarry the information under different circumstances.\n\nFirst bit is encoded as the inversion of visibility access flags\n(bits 2:0). At most one of these flags can be set at any given time.\nInverting these bits therefore produces a value where at least two\nbits are set and there is never any loss of information.\n\nSecond bit is encoded differently for each given type of class\nmember as there is no single unused bit such that setting it would\nnot increase the size of the LEB128 encoding.\n - Bit 5 for fields as it carries no other meaning\n - Bit 5 for non-native methods, as `synchronized` can only be set\n   on native methods\n - Bit 9 for native methods, as it carries no meaning and bit 8\n   (native) will make the LEB128 encoding at least two bytes long\n\nThis tool is meant to be applied on boot class path DEX files and\nas such, this encoding is not part of the DEX specification and may\nchange in the future. Access flags returned by ClassDataItemIterator\nare stripped of these hidden flags and thus fully transparent to the\nruntime.\n\nTest: m test-art-host\nBug: 64382372\nChange-Id: Ifc237ff8a35a8b470b7fc682a9cb879370d1e6e9\n"
