-### Reporting Bugs and getting help
-
-The issue tracker on Github is for bug reports only. It is not a general support forum.
-
-**A bug is everything you can reproduce. ie *if I do this that happens but something else should happen instead*.**
-
-Please search the issue tracker (including closed issues). Your bug might be a server bug that has already been addressed.
-
-Please fill in the template when creating new issues and provide information about your device and your server. The [adb logcat](https://wiki.cyanogenmod.org/w/Doc:_debugging_with_logcat) can be omitted if you can reproduce the bug under every condition. (ie *click button X and the application crashes*) But the adb logcat is required if the bug happens only under certain conditions or involves network problem (Server not found, messages not arriving) 
-
-**If you are seeking help or are unable to reproduce the exact problem please join our MUC at conversations@conference.siacs.eu**

 #### How do I create an account?
-XMPP, like email, is a federated protocol, which means that there is not one company you can create an *official XMPP account* with. Instead there are hundreds, or even thousands, of providers out there. One of those providers is our very own [conversations.im](https://account.conversations.im). If you don’t like to use *conversations.im* use a web search engine of your choice to find another provider. Or maybe your university has one. Or you can run your own. Or ask a friend to run one. Once you've found one, you can use Conversations to create an account. Just select *register new account* on server within the create account dialog.
-
-##### Domain hosting
-Using your own domain not only gives you a more recognizable Jabber ID, it also gives you the flexibility to migrate your account between different XMPP providers. This is a good compromise between the responsibilities of having to operate your own server and the downsides of being dependent on a single provider.

Instead there are hundreds, or even thousands, of providers out there. One of those providers is our very own [chat.sum7.eu](https://chat.sum7.eu). If you don’t like to use *chat.sum7.eu* use a web search engine of your choice to find another provider. Or maybe your university has one. Or you can run your own. Or ask a friend to run one. Once you've found one, you can use Conversations to create an account. Just select *register new account* on server within the create account dialog.

 Some Bind failures are transient and resolve themselves after a reconnect.
 
 When trying to connect to OpenFire the bind failure can be a permanent problem when the domain part of the Jabber ID entered in Conversations doesn’t match the domain the OpenFire server feels responsible for. For example OpenFire is configured to use the domain `a.tld` but the Jabber ID entered is `user@b.tld` where `b.tld` also points to the same host. During bind OpenFire tries to reassign the Jabber to `user@a.tld`. Conversations doesn’t like that.
-This can be fixed by creating a new account in Conversations that uses the Jabber ID `user@a.tld`. 
+This can be fixed by creating a new account in Conversations that uses the Jabber ID `user@a.tld`.
 
 Note: This is kind of a weird quirk in OpenFire. Most other servers would just throw a 'Server not responsible for domain' error instead of attempting to reassign the Jabber ID.
 
 Maybe you attempted to use the Jabber ID `test@b.tld` because `a.tld` doesn’t point to the correct host. In that case you might have to enable the extended connection settings in the expert settings of Conversations and set a host name.

 #### How do XEP-0357: Push Notifications work?
 You need to be running the Play Store version of Conversations and your server needs to support push notifications.¹ Because *Google’s Firebase Cloud Messaging (FCM)* are tied with an API key to a specific app your server can not initiate the push message directly. Instead your server will send the push notification to the [Conversations App server](https://github.com/iNPUTmice/p2) (operated by us) which then acts as a proxy and initiates the push message for you. The push message sent from our App server through FCM doesn’t contain any personal information. It is just an empty message which will wake up your device and tell Conversations to reconnect to your server. The information sent from your server to our App server depends on the configuration of your server but can be limited to your account name. (In any case the Conversations App server won't redirect any information through FCM even if your server sends this information.)

 #### But why do I need a permanent notification if I use Google Push?
-FCM (Google Push) allows an app to wake up from *Doze* which is (as the name suggests) a hibernation feature of the Android operating system that cuts the network connection and also reduces the number of times the app is allowed to wake up (to ping the server for example). The app can ask to be excluded from doze. Non push variants of the app (from F-Droid or if the server doesn’t support it) will do this on first start up. So if you get exemption from *Doze*, or if you get regular push events sent to you, Doze should not pose a threat to Conversatons working properly. But even with *Doze* the app is still open in the background (kept in memory); it is just limited in the actions it can do. Conversations needs to stay in memory to hold certain session state (online status of contacts, join status of group chats, …). However with Android 8 Google changed all of this again and now an App that wants to stay in memory needs to have a foreground service which is visible to the user via the annoying notification. But why does Conversations need to hold that state? XMPP is a stateful protocol that has a lot of per-session information; packets need to be counted, presence information needs to be held, some features like Message Carbons get activated once per session, MAM catchup happens once, service discovery happens only once; the list goes on. When Conversations was created in early 2014 none of this was a problem because apps were just allowed to stay in memory. Basically every XMPP client out there holds that information in memory because it would be a lot more complicated trying to persist it to disk. An entire rewrite of Conversations in the year 2019 would attempt to do that and would probably succeed however it would require exactly that; a complete rewrite which is not feasible right now. That’s by the way also the reason why it is difficult to write an XMPP client on iOS. Or more broadly put this is also the reason why other protocols are designed as or migrated to stateless protocols (often based on HTTP); take for example the migration of IMAP to [JMAP](https://jmap.io/).

 #### How do I backup / move Conversations to a new device?
 On the one hand Conversations supports Message Archive Management to keep a server side history of your messages so when migrating to a new device that device can display your entire history. However that does not work if you enable OMEMO due to its forward secrecy. (Read [The State of Mobile XMPP in 2016](https://gultsch.de/xmpp_2016.html) especially the section on encryption.)

Don't forget to enable the accounts after a successfull restore.
 
 This backup method will include your OMEMO keys. Due to forward secrecy you will not be able to recover messages sent and received between creating the backup and restoring it. If you have a server side archive (MAM) those messages will be retrieved but displayed as *unable to decrypt*. For technical reasons you might also lose the first message you either sent or receive after the restore; for each conversation you have. This message will then also show up as *unable to decrypt*, but this will automatically recover itself as long as both participants are on Conversations 2.3.11+. Note that this doesn’t happen if you just transfer to a new phone and no messages have been exchanged between backup and restore.
 
-In the vast, vast majority of cases you won’t have to manually delete OMEMO keys or do anything like that. Conversations only introduced the offical backup feature in 2.4.0 after making sure the *OMEMO self healing* mechanism introduced in 2.3.11 works fine.

-Conversations is a messenger for the next decade. Based on already established
-internet standards that have been around for over ten years Conversations isn’t
-trying to replace current commercial messengers. It will simply outlive them.
-Commercial, closed source products are coming and going. 15 years ago we had ICQ
-which was replaced by Skype. MySpace was replaced by Facebook. WhatsApp and
-Hangouts will disappear soon. Internet standards however stick around. People
-are still using IRC and e-mail even though these protocols have been around for
-decades. Utilizing proven standards doesn’t mean one can not evolve. GMail has
-revolutionized the way we look at e-mail. Firefox and Chrome have changed the

-messaging. Being less obtrusive than a telephone call instant messaging has
-always played an important role in modern society. Conversations will show that
-instant messaging can be fast, reliable and private. Conversations will not
-force its security and privacy aspects upon the user. For those willing to use
-encryption Conversations will make it as uncomplicated as possible. However
-Conversations is aware that end-to-end encryption by the very principle isn’t
-trivial. Instead of trying the impossible and making encryption easier than
-comparing a fingerprint Conversations will try to educate the willing user and
-explain the necessary steps and the reasons behind them. Those unwilling to
-learn about encryption will still be protected by the design principals of
-Conversations.  Conversations will simply not share or generate certain
-information for example by encouraging the use of federated servers.
-Conversations will always utilize the best available standards for encryption
-and media encoding instead of reinventing the wheel. However it isn’t afraid to
-break with behavior patterns that have been proven ineffective.

-Observations on implementing XMPP
-=================================
-After spending the last two and a half month basically writing my own XMPP
-library from scratch I decided to share some of the observations I made in the
-process. In part this article can be seen as a response to a blog post made by
-Dr. Ing. Georg Lukas. The blog post introduces a couple of XEP (XMPP Extensions)
-which make the life on mobile devices a lot easier but states that they are
-currently very few implementations of those XEPs. So I went ahead and
-implemented all of them in my Android XMPP client.
-
-### General observations
-The first thing I noticed is that XMPP is actually okish designed. If you were
-to design a new chat protocol today you probably wouldn’t choose XML again
-however the protocol basically consists of only three different packages which
-are quickly hidden under some sort of abstraction layer within your library.
-Getting from zero to sending messages to other users actually was very simple
-and straight forward. But then came the XEPs.
-
-### Multi-User Chat
-The first one was XEP-0045 Multi-User Chat. This is the one XEP of the XEPs I’m
-going to mention in my article which is actually wildly adopted. Most clients
-and servers I know of support MUC. However the level of completeness varies.
-MUC actually introduces access and permission roles which are far more complex
-than what some of us are used to from IRC but a lot of clients just don’t
-implement them. I’m not implementing them myself (at least for now) because I
-somewhat doubt that someone would actually use them (however this might be some
-sort of chicken or egg problem). I did find some strange bugs though which might
-be interesting for other library developers. In theory a MUC server
-implementation can allow a  single user (same jid) to join a conference room
-multiple times with the same nick from different clients. This means if someone
-wants to participate in a conference from two different devices (mobile and
-desktop for example) one wouldn’t have to name oneself `userDesktop` and
-`userMobile` but just `user`. Both ejabberd and prosody support this but with
-strange side effects. Prosody for example doesn’t allow a user to change its
-name once two clients are “merged” by having the same nick.
-
-### Carbons and Stream Management
-Two of the other XEPs Lukas mentions — Carbons (XEP-0280) and Stream Management
-(XEP-0198) — were actually fairly easy to implement. The only challenges were to
-find a server to support them (I ended up running my own Prosody server) and a
-desktop client to test them with. For carbons there is a patched Mcabber version
-and Gajim. After implementing stream management I had very good results on my
-mobile device. I had sessions running for up to 24 hours with a walking outside,
-loosing mobile coverage for a few minutes and so on. The only limitation was
-that I had to keep on developing and reinstalling my app.
-
-### Off the record
-And then came OTR... This is were I spend the most time debugging stuff and
-trying to get things right and compatible with other clients. This is the part
-were I want to help other developers not to make the same mistakes and maybe
-come to some sort of consent among XMPP developers to ultimately increase the
-interoperability. OTR has some down sides which make it difficult or at times
-even dangerous to implement within XMPP. First of all it is a synchronous
-protocol which is tunneled through a different protocol (XMPP). Synchronous
-means — among other things — auto replies. (An OTR session begins with “hi I’m
-speaking otr give me your key” “ok cool here is my key”) And auto replies — we
-know that since the first time an out of office auto responder went postal — are
-dangerous. Things really start to get messy when you use one of the best
-features of XMPP — multiple clients. The way XMPP works is that clients are
-encouraged to send their messages to the raw jid and let the server decide what
-full jid the messages are routed to. If in doubt even all of them. So what
-happens when Alice sends a  start-otr-message to Bobs raw jid? Bob receives the
-message on his notebook as well as his cell phone. Both of them answer. Alice
-gets two different replies. Shit explodes. Even if Alice  sends the message to
-bob/notebook chances are that Bob has carbon messages enabled and still receives
-the messages on both devices. Now assuming that Bobs client is clever enough not
-to auto reply to carbonated messages Bob/cellphone will still end up with a lot
-of garbage messages. (Essentially the entire conversation between Alice and
-Bob/notebook but unreadable of course) Therefor it should be good practice to
-tag OTR messages as both private and no-copy (private is part of the carbons
-XEP, no-copy is a general hint). I found that prosody for some reasons doesn’t
-honor the private tag on outgoing messages. While this is easily fixed I presume
-that having both the private and the no-copy tag will make it more compatible
-with servers or clients I don’t know about yet.
-
-#### Rules to follow when implementing OTR
-To summarize my observations on implementing OTR in XMPP let me make the
-following three statements.
-
-1. While it is good practice for unencrypted messages to be send to the raw jid
-and have the receiving server or user decide how they should be routed OTR
-messages must be send to a specific resource. To make this work the user should
-be given the option to select the presence (which can be assisted with some
-educated guessing by the client based on previous messages).  Furthermore a
-client should encourage a user to choose meaningful presences instead of the
-clients name or even random ones. Something like `/mobile`, `/notebook`,
-`/desktop` is a greater assist to any one who wants to start an otr session then
-`/Gajim`, `/mcabber` or `/pidgin`.
-
-2. Messages should be tagged private and no-copy to avoid unnecessary traffic or
-otr error loops with faulty clients. This tagging should be done even if your
-own client doesn’t support carbons.
-
-3. When dealing with “legacy clients” — meaning clients which don’t follow my
-advise — a client should be extra careful not to create message loops. This
-means to not respond with otr errors if a client is not 100% sure it is the only
-client which received the message

-
-Design principles:
-
-* Be as beautiful and easy to use as possible without sacrificing security or privacy
-* Rely on existing, well established protocols
-* Do not require a Google Account or specifically Google Cloud Messaging (GCM)
-* Require as few permissions as possible
-
-Features:
-
-* End-to-end encryption with either <a href="http://conversations.im/omemo/">OMEMO</a> or <a href="http://openpgp.org/about/">OpenPGP</a>
-* Sending and receiving images
-* Intuitive UI that follows Android Design guidelines
-* Pictures / Avatars for your Contacts
-* Syncs with desktop client
-* Conferences (with support for bookmarks)
-* Address book integration
-* Multiple accounts / unified inbox
-* Very low impact on battery life
-
-Conversations makes it very easy to create an account on the conversations.im
-server. Using that server comes with an annual fee of 8 Euro after a 6 month
-trial period. However Conversations will work with any other XMPP server as
-well. A lot of XMPP servers are run by volunteers and are free of charge.
-
-XMPP Features:
-
-Conversations works with every XMPP server out there. However XMPP is an
-extensible protocol. These extensions are standardized as well in so called
-XEP’s. Conversations supports a couple of those to make the overall user
-experience better. There is a chance that your current XMPP server does not
-support these extensions. Therefore to get the most out of Conversations you
-should consider either switching to an XMPP server that does or - even better -
-run your own XMPP server for you and your friends.
-
-These XEPs are - as of now:
-
-* XEP-0065: SOCKS5 Bytestreams (or mod_proxy65). Will be used to transfer files if both parties are behind a firewall (NAT).
-* XEP-0163: Personal Eventing Protocol for avatars
-* XEP-0191: Blocking command lets you blacklist spammers or block contacts without removing them from your roster.
-* XEP-0198: Stream Management allows XMPP to survive small network outages and changes of the underlying TCP connection.
-* XEP-0280: Message Carbons which automatically syncs the messages you send to your desktop client and thus allows you to switch seamlessly from your mobile client to your desktop client and back within one conversation.
-* XEP-0237: Roster Versioning mainly to save bandwidth on poor mobile connections
-* XEP-0313: Message Archive Management synchronize message history with the server. Catch up with messages that were sent while Conversations was offline.
-* XEP-0352: Client State Indication lets the server know whether or not Conversations is in the background. Allows the server to save bandwidth by withholding unimportant packages.
-* XEP-0363: HTTP File Upload allows you to share files in conferences and with offline contacts. Requires an additional component on your server.

-/**
- * Represents the JID as described in <a href="https://tools.ietf.org/html/rfc7622">Extensible Messaging and Presence Protocol (XMPP): Address Format</a>.
- * <p>
- * A JID consists of three parts:
- * <p>
- * [ localpart "@" ] domainpart [ "/" resourcepart ]
- * </p>
- * The easiest way to create a JID is to use the {@link #of(CharSequence)} method:
- * ```java
- * Jid jid = Jid.of("juliet@capulet.lit/balcony");
- * ```
- * You can then get the parts from it via the respective methods:
- * ```java
- * String local = jid.getLocal(); // juliet
- * String domain = jid.getDomain(); // capulet.lit
- * String resource = jid.getResource(); // balcony
- * ```
- * Implementations of this interface should override <code>equals()</code> and <code>hashCode()</code>, so that different instances with the same value are equal:
- * ```java
- * Jid.of("romeo@capulet.lit/balcony").equals(Jid.of("romeo@capulet.lit/balcony")); // true
- * ```
- * The default implementation of this class also supports <a href="https://xmpp.org/extensions/xep-0106.html">XEP-0106: JID Escaping</a>, i.e.
- * ```java
- * Jid.of("d'artagnan@musketeers.lit")
- * ```
- * is escaped as <code>d\\27artagnan@musketeers.lit</code>.
- * <p>
- * Implementations of this interface should be thread-safe and immutable.
