parseRuntimePermissionsLPrでそれぞれのパッケージとパーミッションについて
`ArrayMap<String, PackageSetting> mPackages`のPackageSetting -> grantRuntimePermissionが呼ばれる。
## readStateForUserSyncLPrが呼ばれるタイミング
メソッド呼び出ししてる場所見つからず。。
RuntimePermissionPersistenceというクラスが同じメソッドを持ってるっぽいが、RuntimePermissionPersistenceの定義場所が見つからず。
```
2517 if (users == null) {
2518 readPackageRestrictionsLPr(0);
2519 mRuntimePermissionsPersistence.readStateForUserSyncLPr(UserHandle.USER_OWNER);
2520 } else {
2521 for (UserInfo user : users) {
2522 readPackageRestrictionsLPr(user.id);
2523 mRuntimePermissionsPersistence.readStateForUserSyncLPr(user.id);
2524 }
2525 }
```
## 書き出している場所
```
4250 private void writePermissionsSync(int userId) {
4251 AtomicFile destination = new AtomicFile(getUserRuntimePermissionsFile(userId));
4252
4253 ArrayMap<String, List<PermissionState>> permissionsForPackage = new ArrayMap<>();
4254 ArrayMap<String, List<PermissionState>> permissionsForSharedUser = new ArrayMap<>();
