Are you using the latest version of bugsnag-android? If not, does updating to the latest version fix your issue?
Has somebody else already reported your issue? Feel free to add additional context to or check-in on an existing issue that matches your own.
Is your issue caused by this module? Only things related to the bugsnag-android module should be reported here. For anything else, please contact us directly and we'd be happy to help you out.

Fixing issues

If you've identified a fix to a new or existing issue, we welcome contributions! Here are some helpful suggestions on contributing that help us merge your PR quickly and smoothly:

Fork the library on GitHub
Build and test your changes using the example app and test suite
Commit and push until you are happy with your contribution
Make a pull request
Ensure the automated checks pass (and if it fails, please try to address the cause)

Adding features

Unfortunately we’re unable to accept PRs that add features or refactor the library at this time. However, we’re very eager and welcome to hearing feedback about the library so please contact us directly to discuss your idea, or open a feature request to help us improve the library.

Here’s a bit about our process designing and building the Bugsnag libraries:

We have an internal roadmap to plan out the features we build, and sometimes we will already be planning your suggested feature!
Our open source libraries span many languages and frameworks so we strive to ensure they are idiomatic on the given platform, but also consistent in terminology between platforms. That way the core concepts are familiar whether you adopt Bugsnag for one platform or many.
Finally, one of our goals is to ensure our libraries work reliably, even in crashy, multi-threaded environments. Oftentimes, this requires an intensive engineering design and code review process that adheres to our style and linting guidelines.

Updating dependencies

Most dependencies are controlled by the module-level gradle files, however running the NDK C/C++ components also depends on greatest and parson, managed by clib. Both libraries are vendored into the repository and clib is not required unless updating the dependencies.

To update a clib dependency, reinstall it. For example, using parson:

clib install kgabis/parson -o src/test/cpp/deps --save

Installing the Android SDK

Running ./gradlew can automatically install both the Gradle build system and the Android SDK.

If you already have the Android SDK installed, make sure to export the ANDROID_HOME environment variable, for example:

export ANDROID_HOME=/usr/local/Cellar/android-sdk/23.0.2

If you don't already have the Android SDK installed, it will be automatically installed to ~/.android-sdk.

Note: You'll need to make sure that the adb, android and emulator tools installed as part of the Android SDK are available in your $PATH before building.

Building the Library

Be sure to clone the repository submodules:

git submodule update --init --recursive

You can build new .aar files as follows:

./gradlew sdk:assemble

Files are generated intosdk/build/outputs/aar.

Building with custom ABIs

To build the NDK module with specific ABIs, use the ABI_FILTERS project option:

./gradlew assemble -PABI_FILTERS=x86,arm64-v8a

Running Tests

Running the test suite requires a connected android device or emulator.

Unit tests

You can run the test suite on a device/emulator as follows from within the sdk directory:

./gradlew connectedCheck

End-to-end tests

To run the end-to-end tests, first set up the environment by running Bundler:

bundle install

The tests require two environment variables to be set:

ANDROID_HOME, set the the location of the Android SDK
ANDROID_EMULATOR, set to the name of an installed emulator

Then run the tests using:

bundle exec maze-runner

Running Lint

You can run lint on the project using the following command:

./gradlew lint checkstyle detekt

Building the Example App

You can build and install the example app to as follows:

./gradlew installDebug

This builds the latest version of the library and installs an app onto your device/emulator.

Installing/testing against a local maven repository

Sometimes its helpful to build and install the bugsnag-android libraries into a local repository and test the entire dependency flow inside of a sample application.

To get started:

In the bugsnag-android directory, run ./gradlew assembleRelease publishSDKPublicationToMavenLocal && ./gradlew assembleRelease publishSDKPublicationToMavenLocal -PreleaseNdkArtefact=true. This installs bugsnag-android and bugsnag-android-ndk into your local maven repository.
In your sample application build.gradle, add mavenLocal() to the top of your allprojects repositories section:
```
allprojects {
  repositories {
    mavenLocal()
    // other repos as needed
  }
}
```
In your sample application app/build.gradle, add the following to the dependencies section, inserting the exact version number required:
```
dependencies {
  implementation 'com.bugsnag:bugsnag-android-ndk:[VERSION NUMBER]'
}
```
Clean your sample application and reload dependencies every time you rebuild/republish the local dependencies:
```
./gradlew clean --refresh-dependencies
```

Releasing a New Version

If you are a project maintainer, you can build and release a new version of bugsnag-android as follows:

One-time setup

Create a Bintray account, and ask a Bugsnag admin to add you to the organisation
Create a Sonatype JIRA account
Ask in the Bugsnag Sonatype JIRA ticket to become a contributor
Ask an existing contributor (likely Simon) to confirm in the ticket
Wait for Sonatype them to confirm the approval

Create a file ~/.gradle/gradle.properties with the following contents:

# Your credentials for https://oss.sonatype.org/
# NOTE: An equals sign (`=`) in any of these fields will break the parser
# NOTE: Do not wrap any field in quotes

NEXUS_USERNAME=your-nexus-username
NEXUS_PASSWORD=your-nexus-password
nexusUsername=your-nexus-username
nexusPassword=your-nexus-password

# Your credentials for Bintray
# From https://bintray.com/profile
bintray_user=your-bintray-username
# Get your Bintray API key from https://bintray.com/profile/edit > API Key
bintray_api_key=your-api-key

# GPG key details
# Your key must be added to a public key server, such as http://keys.gnupg.net:
# 1. Get your key id by running `gpg --list-keys --keyid-format=short`. It
#    should be 8-character hexadecimal.
# 2. Export your key using `gpg --armor --export <key-id>`
# 3. Upload to a server using `gpg --keyserver hkp://keys.gnupg.net --send-keys <key-id>`
signing.keyId=<key-id>
signing.password=your-gpg-key-passphrase
signing.secretKeyRingFile=/Users/{username}/.gnupg/secring.gpg

Every time

Pre-release Checklist

Does the build pass on the CI server?
Are all Docs PRs ready to go?
Do the installation instructions work when creating an example app from scratch?
Has all new functionality been manually tested on a release build?
- Ensure the example app sends an unhandled error
- Ensure the example app sends a handled error
- If a response is not received from the server, is the report queued for later?
- If no network connection is available, is the report queued for later?
- On a throttled network, is the request timeout reasonable, and the main thread not blocked by any visible UI freeze? (Throttling can be achieved by setting both endpoints to "https://httpstat.us/200?sleep=5000")
- Are queued reports sent asynchronously?
Native functionality checks:
- Rotate the device before notifying. Is the orientation at the time persisted in the report on the dashboard?
- Rotate the device before causing a native crash. Is the orientation at the time of the crash persisted in the report on the dashboard?
- Wait a few seconds before a native crash. Does the reported duration in foreground match your expectation? Is the value for "inForeground" correct?
- Do the function names demangle correctly when using notify?
Have the installation instructions been updated on the dashboard as well as the docs site?
Do the installation instructions work for a manual integration?

Making the release

Make a PR to release the following changes to master, creating a release branch from the "next" branch if this is a feature release:
- Update the version number and dex count badge by running make VERSION=[number] bump
- Inspect the updated CHANGELOG, README, and version files to ensure they are correct
Once merged:
- Pull the latest changes (checking out master if necessary) and build by running ./gradlew sdk:assembleRelease
- Release to GitHub:
  - Run git tag vX.X.X && git push origin --tags
  - Create a release from your new tag on GitHub Releases
  - Upload the generated .aar file from {sdk,ndk}/build/outputs/aar/bugsnag-android-*.aar
- Release to Maven Central and Bintray by running ./gradlew sdk:assembleRelease publish bintrayUpload && ./gradlew sdk:assembleRelease publish bintrayUpload -PreleaseNdkArtefact=true
- "Promote" the release build on Maven Central:
  - Go to the sonatype open source dashboard
  - Click the search box at the top right, and type “com.bugsnag”
  - Select the com.bugsnag staging repository
  - Click the “close” button in the toolbar, no message
  - Click the “refresh” button
  - Select the com.bugsnag closed repository
  - Click the “release” button in the toolbar
- Open the Bintray repositories and publish the new artifacts:
  - SDK repo
  - NDK repo
Merge outstanding docs PRs related to this release

Post-release Checklist

(May take some time to propagate to maven central and bintray)

Have all Docs PRs been merged?
Can a freshly created example app send an error report from a release build using the released artefact?
Do the existing example apps send an error report using the released artifact?
Make releases to downstream libraries, if appropriate (generally for bug fixes)
