This is a special profile folder where apps will leave profile markers for the dex files they load and don't own. System server will read the markers and decide which apk should be fully compiled instead of profile guide compiled. Apps need only to be able to create (touch) files in this directory. System server needs only to be able to check wheter or not a file with a given name exists. Bug: 27334750 Bug: 26080105 Change-Id: I2256e4aba1ec0e5117de6497123223b9a74f404e
