Android Dev Tools is a library that contains various QA/Debug tools to speed up and streamline the development progress.

Tools

• Autofill Service
• Analytics Logger
• Http Inspector (Alpha)
• Environment Manager
• Debug Menu
• DeepLink Launcher
• SharedPref Manager

Autofill Service

Autofill Service allows developers and QA to fill form inputs automatically with predefined form data.

How it Works?

It observes both activity and fragment lifecycle events via application class to detect layout inflations. After each inflation, it seeks for determined input views in the inflated layout. If it has all required inputs, then shows the autofill action. Autofill data that suitable with inflated form inputs are shown in the selection dialog.

Demo

Usage

Autofill will automatically started if added as dependency. It checks autofill.json file on assets directory of the project. If you want to disable Autofill to be initialized, you can modify AndroidManifest.xml like below on main or desired flavor/variant.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <application>

        <provider
            android:name="androidx.startup.InitializationProvider"
            android:authorities="${applicationId}.androidx-startup"
            tools:node="remove">

            <meta-data
                android:name="com.trendyol.android.devtools.autofillservice.AutofillInitializer"
                android:value="androidx.startup" />
        </provider>
    </application>
</manifest>

Configuration

Configuration Json file can be located in /[variant/flavor or main]/assets folder. You can define autofill data by following this structure. You should also note that the order of the defined form field resource id's and order of input values must match.

{
  "forms": [
    {
      "fields": ["inputEmail", "inputPassword"],
      "matchAnyField": true,
      "categories": {
        "Temporary Users": [
          { "description": "Temporary test user.", "values": ["[email protected]", "123456"] },
          { "description": "Temporary tool user.", "values": ["[email protected]", "123456"] }
        ],
        "Test Users": [
          { "description": "Test regular user.", "values": ["[email protected]", "123456"] },
          { "description": "Test tool user.", "values": ["[email protected]", "123456"] }
        ]
      }
    }
  ]
}

• forms object declares the forms that will be cheched on activity/fragment screen.
• fields are input view ids.
• matchAnyField is optional flag to enable the feature whether if all fields should be exist or not. Default is false.
• categories declares inputs, you can provide multiple category and multiple input values.

Setup

Since Autofill not requires any initialization code, all you need to add the dependency on desired variant/flavor like below.

dependencies {

    debugImplementation("com.trendyol.android.devtools:autofill-service:$version")
}

Analytics Logger

Analytics Logger allows to log & inspect analytics events sent by client.

Demo

Usage

AnalyticsLogger.init(applicationContext)

AnalyticsLogger.report(
    key = "eventKey",
    value = "{\"category\": \"Cart\", \"data\": \"TestData\" }", // Should be Json string.
    platform = "EventPlatform",
)

Setup

"com.trendyol.android.devtools:analytics-logger:$version"
"com.trendyol.android.devtools:analytics-logger-no-op:$version"

Http Inspector (Alpha)

Http Inspector provides an OkHttp interceptor and web interface to inspect, manipulate in realtime and mock HTTP request and responses.

You can access the web client with http://deviceip:5001. If you are running on virtual a device, you need to forward port by adb forward tcp:5001 tcp:5001.

How it Works

Any request passing through the interceptor is held in the request queue to sync with each other. Held requests are being sent to the web interface via Ktor local webserver. After doing any changes in the response data using web interface, it waits for the acceptance, then sends manipulated response back to the request queue. The actual response data is replaced with the manipulated one and reflected to the application.

Mocking Requests

With this feature, we can imitate the API by preparing mock request and response data for the REST API that has not been prepared yet. It provides a web interface where we can create mock request and response data, and allows us to enable/disable the previously added mock data. The point to be considered is which requests will be answered with mock data rather than going to the real API is decided by comparing the URL, method and request body data of the request in the real request and mock data. If this data is completely matched, the mock response will be served to the client.

Usage

val client = OkHttpClient.Builder()
    .addInterceptor(MockInterceptor(context))
    .build()

Setup

"com.trendyol.android.devtools:http-inspector:$version"
"com.trendyol.android.devtools:http-inspector-no-op:$version"

Environment Manager

Environment Manager provides environment selection dialog can be opened from the app notifications with predefined environment data.

Setup

"com.trendyol.android.devtools:environment-manager:$version"

Debug Menu

Debug Menu provides a debug page build with predefined custom action and events.

Setup

"com.trendyol.android.devtools:debug-menu:$version"

DeepLink Launcher(Beta)

DeepLink Launcher allows you, trigger deepLinks, and keep triggered deepLinks in history.

When a deepLink launched, it will be recorded to roomDB. And recorded datas will be listed under the History Tab.

And also you can import your deepLinks data to DeepLink Launcher. They will be listed under the APP'S DEEPLINK tab.

Demo

Initialize

You need to initialize it first

DeepLinkLauncher.init(this)

If you have a deepLink json file which is includes your app deepLinks, you can init them like that. That's an optional area.

DeepLinkLauncher.importAppDeepLinks(jsonString)

For importing external list to DeepLink Launcher, your json format be like that sample:

{
    "deepLinks": [
        "dl://?Page=Home&Tab=Man",
        "dl://?Page=AppLink&Data=1",
        "dl://?Page=AppLink&Data=2"
    ]
}

Usage

And just call this function to open DeepLink Launcher screen.

DeepLinkLauncher.show()

Setup

"com.trendyol.android.devtools:deeplink-launcher:$version"

SharedPref Manager

SharedPref Manager allows you manage shared preferences

Demo

Initialize

You need to initialize the library with with your android.app.Application instance.

SharedPrefManager.init(this)

Usage

And just call this function to open SharedPref Manager screen.

SharedPrefManager.show("shared_pref_name")

Setup

"com.trendyol.android.devtools:sharedpref-manager:$version"
