|
| public final boolean | isOwner()Returns true if this UserHandle refers to the owner user; false otherwise.
return this.equals(OWNER);
|
| public static final boolean | isSameApp(int uid1, int uid2)Checks to see if both uids are referring to the same app id, ignoring the user id part of the
uids.
return getAppId(uid1) == getAppId(uid2);
|
| public static final boolean | isSameUser(int uid1, int uid2)Checks to see if the user id is the same for the two uids, i.e., they belong to the same
user.

|
| public static final int | myUserId()Returns the user id of the current process
return getUserId(Process.myUid());
|
| public static android.os.UserHandle | readFromParcel(Parcel in)Read a UserHandle from a Parcel that was previously written
with {@link #writeToParcel(UserHandle, Parcel)}, returning either
a null or new object as appropriate.
int h = in.readInt();
return h != USER_NULL ? new UserHandle(h) : null;
|
| public java.lang.String | toString()
return "UserHandle{" + mHandle + "}";
|
| public void | writeToParcel(Parcel out, int flags)
out.writeInt(mHandle);
|
| public static void | writeToParcel(android.os.UserHandle h, Parcel out)Write a UserHandle to a Parcel, handling null pointers. Must be
read with {@link #readFromParcel(Parcel)}.

} else {
out.writeInt(USER_NULL);
