* [Report the issue](https://github.com/nextcloud/talk-android/issues/new/choose) and choose bug report or feature request. The template includes all the information we need to track down the issue.
* This repository is *only* for issues within the Nextcloud Talk Android app code. Issues in other components should be reported in their own repositories, e.g. [Nextcloud server](https://github.com/nextcloud/server/issues)
* Search the [existing issues](https://github.com/nextcloud/talk-android/issues) first, it's likely that your issue was already reported.
* Feature releases will always be based on ```master```
* Bug fix releases will always be based on their respective feature-release-bug-fix-branches
* Bug fixes relevant for the most recent _and_ released feature (e.g. ```11.0.0```) or bugfix (e.g. ```11.2.1```) release will be backported to the respective bugfix branch (e.g. ```stable-11.0``` or ```stable-11.2```)
* Hot fixes not relevant for an upcoming feature release but the latest release can target the bug fix branch directly
We use the Developer Certificate of Origin (DCO) as a additional safeguard for the Nextcloud project.
This is a well established and widely used mechanism to assure contributors have confirmed their right to license their contribution under the project's license.
To make sure your new pull request does not contain commits which are already contained in previous PRs, create a new branch which is a clone of upstream/master.
If you create a new file it needs to contain a license header. We encourage you to use the same license (GPL3+) as we do.

## File naming
The file naming patterns are inspired and based on [Ribot's Android Project And Code Guidelines](https://github.com/ribot/android-guidelines/blob/c1d8c9c904eb31bf01fe24aadb963b74281fe79a/project_and_code_guidelines.md).
### Menu files
Similar to layout files, menu files should match the name of the component. For example, if we are defining a menu file that is going to be used in the `UserProfileActivity`, then the name of the file should be `activity_user_profile.xml`. Same pattern applies for menus used in adapter view items, dialogs, etc.
A good practice is to not include the word `menu` as part of the name because these files are already located in the `menu` directory. In case a component uses several menus in different places (via popup menus) then the resource name would be extended. For example, if the user profile activity has two popup menus for configuring the users settings and one for the handling group assignments then the file names for the menus would be: `activity_user_profile_user_settings.xml` and `activity_user_profile_group_assignments.xml`.
We manage translations via [Transifex](https://app.transifex.com/nextcloud/nextcloud/talk-android/). So just request
joining the translation team for Android on the site and start translating. All translations will then be automatically pushed to this repository, there is no need for any pull request for translations.
When submitting PRs with changed translations, please only submit changes to values/strings.xml and not changes to translated files. These will be overwritten by the next merge of transifex-but and would increase PR review efforts.
## Engineering practices
This section contains some general guidelines for new contributors, based on common issues flagged during code review.
### Approach to technical debt
TL;DR Non-Stop Litter Picking Party!
We recognize the importance of technical debt that can slow down development, make bug fixing difficult and
discourage future contributors.
We are mindful of the [Broken Windows Theory](https://en.wikipedia.org/wiki/Broken_windows_theory) and we'd like to
actively promote and encourage contributors to apply The Scout's Rule: *"Always leave the campground cleaner than
you found it"*. Simple, little improvements will sum up and will be very appreciated by Nextcloud team.
We also promise to actively support and mentor contributors that help us to improve code quality, as we understand
that this process is challenging and requires deep understanding of the application codebase.
Pull Requests that have been tested and reviewed can go to master. After the last alpha release is out in the wild and no mayor errors get reported (by users or in the developer console) the master branch is ready for the stable release phase.
So when we decide to go for a new release we freeze the master feature wise and a stable branch will be created.
_stable beta_ releases done via the Beta program of the Google Play store.
Whenever a PR is reviewed/approved we put it on master.
Before releasing a new stable version there is at least one release candidate. It is based on the current stable-branch. After a beta testing phase a stable version will be released, which is identical to the latest release candidate.
For _stable_ and _release candidate_ the version name follows the [semantic versioning schema](http://semver.org/) and the version number has several digits reserved to parts of the versioning schema inspired by the [jayway version numbering](https://www.jayway.com/2015/03/11/automatic-versioncode-generation-in-android-gradle/), where:
* 2 digits for beta/alpha code as in release candidates starting at '01' (1-50=Alpha / 51-89=RC / 90-99=stable)
Beware that beta releases for an upcoming version will always use the minor and hotfix version of the release they are targeting. So to make sure the version code of the upcoming stable release will always be higher stable releases set the 2 beta digits to '90'-'99' as seen above in the examples. For major versions, as we're not a library and thus 'incompatible API changes' is not something that happens, decisions are essentially marketing-based. If we deem a release to be very impactful, we might increase the major version number.
* major releases are linked to the corresponding [server-releases](https://apps.nextcloud.com/apps/spreed/releases) with aligned release date and version number (server version = 11 = client version)
* feature releases are planned every ~2 months, with 6 weeks of developing and 2 weeks of stabilising
Hotfixes as well as security fixes are released via bugfix releases (dot releases) but are released on demand in contrast to regular, scheduled bugfix releases.
To get an idea which PRs and issues will be part of the next release simply check our [milestone plan](https://github.com/nextcloud/talk-android/milestones)
1. Bump the version name and version code in the [/app/build.gradle](https://github.com/nextcloud/talk-android/blob/master/app/build.gradle), see chapter 'Version Name and number'.
2. Create a [release/tag](https://github.com/nextcloud/talk-android/releases) in git. Tag name following the naming schema: ```stable-Mayor.Minor.Hotfix``` (e.g. stable-1.2.0) naming the version number following the [semantic versioning schema](http://semver.org/)
Release Candidate releases are based on the git [stable-*](https://github.com/nextcloud/talk-android/branches/all?query=stable-) and are before publishing stable releases.
1. Bump the version name and version code in the [/app/build.gradle](https://github.com/nextcloud/talk-android/blob/master/app/build.gradle), see below the version name and code concept.
2. Create a [release/tag](https://github.com/nextcloud/talk-android/releases) in git. Tag name following the naming schema: ```rc-Mayor.Minor.Hotfix-betaIncrement``` (e.g. rc-1.2.0-12) naming the version number following the [semantic versioning schema](http://semver.org/)
Release Candidate releases are based on the git [master](https://github.com/nextcloud/talk-android) and are done between stable releases.
1. Bump the version name and version code in the [/app/build.gradle](https://github.com/nextcloud/talk-android/blob/master/app/build.gradle), see below the version name and code concept.
