Before you begin#

Before you start developing your application with the SyncStage SDK, you need to opt-in to Early Access Developer program and get your SyncStage SDK secrets. Once you have opted-in we will contact you to provide you with your SDK secrets. The SDK secrets are your credentials that authenticates requests associated with your project.

Become an Early Access Developer

Start with an example project#

The best way to start with SyncStage is by trying out our example project available on GitHub SyncStage Test App for Android.

Use SyncStage SDK in your application#

1. Add package dependency#

In the settings.gradle add SyncStage maven repository under dependencyResolutionManagement block. Please define githubProperties which will be used for package repository authentication.

def githubProperties = new Properties()
githubProperties.load(new FileInputStream(""))

dependencyResolutionManagement {
    repositories {
        maven {
            url = uri("")
            credentials {
                username = githubProperties['gpr.usr'] ?: System.getenv("GPR_USER")
                password = githubProperties['gpr.key'] ?: System.getenv("GPR_API_KEY")

Android studio needs GitHub credentials with read:packages permission to fetch the SDK package.

In order to provide GitHub credentials please create a file in the root directory and paste following code:


Under gpr.usr please provide you GitHub login, and under gpr.key paste GitHub token with read:packages permission. For information how to generate token please refer here.

2. Add the following permissions to AndroidManifest.xml#

<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Please note that most of those notifications must accepted by user explicitly.

3. Add SyncStageSecret.json to your Android Studio project to the assets folder#

SyncStageSecret.json is assigned to one application. File contains confidential credentials that allow access to your SyncStage resources.

Security tip

We strongly recommend storing SyncStageSecret.json securely in your backend and provide it as a parameter at SyncStage SDK object instantiation. Having implemented the supply of the SyncStageSecret.json from your protected backend, you can remove the .json from the build.

4. Integrate the SyncStage class with your app#

Here you can find a list of:

5. Use SyncStage in background#

To allow SyncStage work in background you need to create a foreground service of microphone type. Service and additional permissions must be added to AndroidManifest.xml.



<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

6. Handle exiting application gracefully#

Use a method for stopping and cleaning app all the SDK's background tasks. See here) for more details.


SDK does not work as expected, but the application is building and running, what can I do about it?#

Some problems might occur if the application user did not grant all required permissions on their device. Before using the SyncStage object, make sure that all of the required permissions are granted.
