DittoAndroidTools

DittoAndroidTools are diagnostic tools for Ditto. You can view connected peers, export debug logs, browse collections/documents and see Ditto's disk usage/ export this data.

These tools are available through Maven.

For support, please contact Ditto Support (support@ditto.live).

Requirements

Android 8.0+
Jetpack Compose

Installing

Ditto tools are released via Maven Central. Be sure to include it in your list of repositories.

Usage

First, you must initialize Ditto:

val androidDependencies = DefaultAndroidDittoDependencies(applicationContext)
val identity = DittoIdentity.OnlinePlayground(androidDependencies, appId = "YOUR_APPID", token = "YOUR_TOKEN", enableDittoCloudSync = true)
ditto = Ditto(androidDependencies, identity)
DittoLogger.minimumLogLevel = DittoLogLevel.DEBUG
ditto.startSync()

NOTICE: This project loads ditto's credentials from local.properties

ditto.onlinePlayground.appId="YOUR_APPID"
ditto.onlinePlayground.token="YOUR_TOKEN"

1. Tools Viewer

Tools viewer is the easiest way to integrate all the tools currently available. It provides a single entry point to interact with all other tools, and includes them as a dependency.

It is available as a Composable element that requires a Ditto instance. Optional parameters include:

modifier: If you need to adjust the layout
onExitTools: Lambda function that will be called when the "Exit Tools" button is tapped. Use this to do any back navigation or dismissal of the tools composable if you need to.

Example code:

// minimum code required to get started
DittoToolsViewer(
    ditto = YOUR_DITTO_INSTANCE
)

To integrate it in a Views-based app - see instructions here: https://developer.android.com/develop/ui/compose/migrate/interoperability-apis/compose-in-views

Download

Gradle:

dependencies {
    implementation 'live.ditto:dittotoolsviewer:YOUR_LIBRARY_VERSION'
}

2. Presence Viewer

The Presence Viewer displays a mesh graph that allows you to see all connected peers within the mesh and the transport that each peer is using to make a connection.

Within a Composable, you pass ditto to the constructor:

DittoPresenceViewer(ditto = ditto)

Download

Gradle:

dependencies {
  implementation 'live.ditto:dittopresenceviewer:YOUR_LIBRARY_VERSION'
}

Maven:

<dependency>
    <groupId>live.ditto</groupId>
    <artifactId>dittopresenceviewer</artifactId>
    <version>YOUR_LIBRARY_VERSION</version>
</dependency>

3. Data Browser

The Ditto Data Browser allows you to view all your collections, documents within each collection and the propeties/values of a document. With the Data Browser, you can observe any changes that are made to your collections and documents in real time.

Within a Composable function, you pass ditto to the constructor:

DittoDataBrowser(ditto = ditto)

Standalone App

If you are using the Data Browser as a standalone app, there is a button, Start Subscriptions, you must press in order to start syncing data. If you are embedding the Data Browser into another application then you do not need to press Start Subscriptions as you should already have your subscriptions running.

Download

Gradle:

dependencies {
  implementation 'live.ditto:dittodatabrowser:YOUR_LIBRARY_VERSION'
}

Maven:

<dependency>
    <groupId>live.ditto.</groupId>
    <artifactId>dittodatabrowser</artifactId>
    <version>YOUR_LIBRARY_VERSION</version>
</dependency>

4. Export Logs

Export Logs allows you to export logs from your application into a file.

Include ExportLogs() in your Composable function. You can pass in a lambda function to be called when the dialog is dismissed.

ExportLogs(onDismiss: () -> Unit)

Download

Gradle:

dependencies {
  implementation 'live.ditto:dittoexportlogs:YOUR_LIBRARY_VERSION'
}

Maven:

<dependency>
    <groupId>live.ditto</groupId>
    <artifactId>dittoexportlogs</artifactId>
    <version>YOUR_LIBRARY_VERSION</version>
</dependency>

5. Disk Usage/ Export Data

Disk Usage allows you to see Ditto's file space usage.
Export Data allows you to export the Ditto directory.

DittoDiskUsage(ditto = ditto)

Download

Gradle:

dependencies {
  implementation 'live.ditto:dittodiskusage:YOUR_LIBRARY_VERSION'
}

Maven:

<dependency>
    <groupId>live.ditto</groupId>
    <artifactId>dittodiskusage</artifactId>
    <version>YOUR_LIBRARY_VERSION</version>
</dependency>

6. Health

Health allows you to see the status of Ditto's services.

Example: WiFi/Bluetooth state/permissions, device capabilities

The default implementation is a Composable that displays all facets of information.

HealthScreen()

This Composable also takes in an optional list of enum's if you need to show/hide certain groups of information. Current valid enums are:

TRANSPORT_HEALTH -- shows WiFi/Bluetooth status (enabled/disabled, permissions state) 
WIFI_AWARE_STATE -- displays whether the device supports WiFi Aware

Download

Gradle:

dependencies {
  implementation 'live.ditto:health:YOUR_LIBRARY_VERSION'
}

Maven:

<dependency>
    <groupId>live.ditto</groupId>
    <artifactId>health</artifactId>
    <version>YOUR_LIBRARY_VERSION</version>
</dependency>

7. Heartbeat

The Ditto Heartbeat tool allows you to monitor, locally or remotely, the peers in your mesh.

Configure Heartbeat

These are the values you need to provide to the Heartbeat:

id - Unique value that identifies the device
secondsInterval - The frequency at which the Heartbeat will scrape the data
metaData - Optional - any metadata you wish to add to the Heartbeat
healthMetricProviders List of HealthMetricProviders
publishToDittoCollection - Optional - set to false to prevent from publishing the heartbeat to Ditto collection. Default true.

Available healthMetricProviders:

HealthViewModel() - health metrics for Permissions Health Tool
DiskUsageViewModel() - health metrics for Ditto disk usage. isHealthy is determined by the size of the ditto_store and ditto_replication folders. The default isHealthy size is 2GB, but this can be configured.

There is a DittoHeartbeatConfig data class you can use to construct your configuration.

// Provided with the Heartbeat tool
data class DittoHeartbeatConfig(
    val id: String,
    val secondsInterval: Int,
    val metaData: Map<String, Any>? = null,
    val healthMetricProviders: List<HealthMetricProvider>?,
    val publishToDittoCollection: Boolean = true // Toggle to avoid publishing
)

// Example:
// User defines the values here
// Passed into Heartbeat tool
var healthMetricProviders: MutableList<HealthMetricProvider> = mutableListOf()
val diskUsageViewModel = DiskUsageViewModel()
diskUsageViewModel.isHealthyMBSizeLimit = 2048 //2GB worth of data
healthMetricProviders.add(diskUsageViewModel)
val config = DittoHeartbeatConfig(
    id = <unique device id>,
    secondsInterval = 30, //seconds
    metaData = mapOf(
        "deviceType" to "KDS"
    ),
    healthMetricProviders = healthMetricProviders,
    publishToDittoCollection = true
)

// Provide the config and your Ditto instance to startHearbeat()
startHeartbeat(ditto, config).collect { heartbeatInfo = it }

User Interface

You will need to provide your own UI. You can see an example here.

There are two ways you can access the data:

The Ditto collection you provided
startHeartBeat() provides a callback with the data

Ditto Collection:

This is the model of the data and what you can use for reference

{
    _id: <ditto peerKeyString>,
    _schema: String,
    secondsInterval: String,
    presenceSnapshotDirectlyConnectedPeersCount: Int,
    lastUpdated: String (ISO-8601),
    sdk: String,
    presenceSnapshotDirectlyConnectedPeers: {
        <peerKeyString>: {
            deviceName: String,
            sdk: String,
            isConnectedToDittoCloud: Bool,
            bluetooth: Int,
            p2pWifi: Int,
            lan: Int,
        },
        <peerKeyString>…,
        …
    },
    metaData: {},
    healthMetrics: {},
}

Callback:

You will receive a HeartbeatInfo data class back

data class DittoHeartbeatInfo(
    val id: String,
    val schema: String,
    val lastUpdated: String,
    val metaData: Map<String, Any>?,
    val secondsInterval: Int,
    val presenceSnapshotDirectlyConnectedPeersCount: Int,
    val presenceSnapshotDirectlyConnectedPeers: Map<String, Any>,
    val sdk: String,
    var healthMetrics: MutableMap<String, HealthMetric> = mutableMapOf()

)

Download

Gradle:

dependencies {
  implementation 'live.ditto:dittoheartbeat:YOUR_LIBRARY_VERSION'
}

Maven:

<dependency>
    <groupId>live.ditto.</groupId>
    <artifactId>dittoheartbeat</artifactId>
    <version>YOUR_LIBRARY_VERSION</version>
</dependency>

8. Presence Degradation Reporter

Tracks the status of your mesh, allowing to define the minimum of required peers that needs to be connected. Exposes an API to notify when the condition of minimum required peers is not met.

## UI Composable
PresenceDegradationReporterScreen(ditto = ditto)

## API
ditto.presenceDegradationReporterFlow().collect { state ->
    // state.settings
    // state.localPeer
    // state.remotePeers
}

Gradle:

dependencies {
  implementation 'live.ditto:presencedegradationreporter:YOUR_LIBRARY_VERSION'
}

Maven:

<dependency>
    <groupId>live.ditto</groupId>
    <artifactId>presencedegradationreporter</artifactId>
    <version>YOUR_LIBRARY_VERSION</version>
</dependency>

Testing Changes Locally

There are two ways you can test things locally. Either in the demo app, or in an external project.

Testing in the Demo App Locally

To test your changes to a module in the demo app, simply import the local module, making sure to comment out/delete the version catalog import. For example, if you made changes to DittoDataBrowser you would

add: implementation(project(":DittoDataBrowser")) remove/comment out: implementation libs.live.ditto.databrowser

Testing in an External Project

Run ./gradlew publishToMavenLocal
In your external project add the mavenLocal() entry to your list of repository sources
When importing a tool, the version will be SNAPSHOT
