Getting started profiler #

Contextual Profiler SDK offers a comprehensive and efficient solution for collecting valuable information about your users. With this powerful tool, you will be able to gather relevant data that will allow you to conduct in-depth analysis and gain a clear understanding of your users' behavior, preferences, and needs.

⚠️ Important Notice: This library does not support iOS devices.

Please be aware that this library is currently only available for Android. It will not work on iOS devices. Ensure that your project is intended for Android platforms before integrating this library.

See the full API for more methods.

Recommendations #

• FLUTTER: >= 3.3.0
• ANDROID API LEVEL: 21 to 33 (we recommend 24 to 34)
• MIN JAVA VERSION: jdk11
• GRADLE DISTRIBUTION: gradle-7.5.1

Installation #

Please read this entire section.

Android #

Proguard #

If you have any obsfucastion tool in your project, you'll need to exclude this package to work as intended in release builds.

Create a new file called proguard-rules.pro in /android/app with this content:

-keep class com.fivvy.profiler.** { *; }
-keep class * extends com.fivvy.profiler.** { *; }

-keepclassmembers class com.fivvy.profiler.** {
    *;
}

-keepattributes *Annotation*

Add the following settings in build.gradle within /android/app

    buildTypes {
        release {
            ...
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

Gradle config #

you MUST add this line to build.gradle (proyect)

allprojects {
    repositories {
        google()
        mavenCentral()
          maven {
            url "https://gitlab.com/api/v4/projects/58175283/packages/maven"
        }
    }
}

and in build.gradle (app)

    implementation 'com.fivvy:fivvy-lib:2.1.0@aar'

Permissions

AndroidManifest #

Necesary to add this xmlns:tools insde the tag manifest on AndroidManifest.xml insde android/app/src/main folder.

<manifest 
  <!-- Others manifest properties -->
  xmlns:tools="http://schemas.android.com/tools"
>

Need to add these permissions in the AndroidManifes.xml file inside android/app/src/main before aplication tag.

<manifest>
  <!-- others aplications tags -->
  <uses-permission  android:name="android.permission.INTERNET" />
  <uses-permission  android:name="android.permission.PACKAGE_USAGE_STATS"  tools:ignore="ProtectedPermissions" />

  <!-- List of apps that you want to check on customer device -->
  <queries>
    <!-- List of package's [Max 100] -->
    <package android:name="com.whatsapp"/> <!-- WhatsApp Messenger -->
    <package android:name="com.facebook.katana"/> <!-- Facebook -->
    <package android:name="com.mercadopago.android"/> <!-- Mercado Pago -->
    
  </queries>

  <application>
    <!-- ... -->
  </application>
</manifest>

Integration in App #

On android you must request permissions beforehand

Init of plugin #

First of all, you will need to instantiated previously the ContextualProfiler plugin on the Widget where you will use the methods.

import 'package:profiler/plugin/contextual_profiler.dart';

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  // ADD THIS LINE
  final _profilerPlugin = ContextualProfiler();

  // Your Code
}

Get user permission to check the app's usage #

This is an exclusive custom dialog that you can invoke in your app to get bring a easy way to request access usage permission from the user.

First you need to add a function to transform an image to a byte array.

Future<Uint8List> loadImageBytes(String assetPath) async {
    final ByteData data = await rootBundle.load(assetPath);
    return data.buffer.asUint8List(data.offsetInBytes, data.lengthInBytes);
  }

then implement this method: 
 Future<void> openAccessUsageSettings() async {
    String platformVersion;

       final Uint8List imageBytes = await loadImageBytes("assets/images/logo.png");


    final usageSetting = UsageSetting(
      language: "ES", // If selected, the default texts will be set on the modal for EN, ES, or PR.
      // If using the ln value, it is recommended not to use the parameters below as the ln sets default texts in the right language.
      appName: 'Fivvy', // string value with your app name
       imagePath:
        imageBytes, // this image should be in android/app/src/main/res/drawable/logo.png
      appDescription: 'Activate the permission', // optional description text. Recommended length: 3 or 4 words
      modalText: 'Lorem ipsum text', // optional modal text. Recommended length: 3 or 4 words
      dialogTitle: "Dialog Title", // Title of the dialog displayed to the user before redirecting to the settings screen for permissions.
      dialogMessage1: "Dialog message 1", // Custom Message of the dialog displayed to the user before redirecting to the settings screen for permissions.
      dialogMessage2: "Dialog message 2", // Other custom Message of the dialog displayed to the user before redirecting to the settings screen for permissions.
      blacklist: null // (Optional) List of device manufacturers for which the usage settings should be avoided. On some devices, especially from certain manufacturers as Xiaomi, a system warning might be displayed when attempting to access the usage settings. To prevent this action on those devices, you can:

      //- Pass `null`: This will apply a default list of manufacturers known to have this issue.
      // - Provide a custom list of manufacturers as an array (`["manufacturer1", "manufacturer2"]`): This will prevent the settings from being accessed only on devices from those specific brands.
      //- Pass an empty array `[]`: This will allow the settings to be accessed on all devices without any restrictions.

    );
    try {
      await _profilerPlugin.openUsageAccessSettings(usageSetting);
      platformVersion = 'opened successfully';
    } on PlatformException {
      platformVersion = 'Failed to open Access Usage Settings.';
    }

    if (!mounted) return;

    setState(() {
      _response = platformVersion;
    });
  }

also add to .yaml file the asset:

flutter:
  assets:
    - assets/images/logo.png

Another option #

However, there is a separate function in case you want to create a custom dialog that best suits your application. Consider having the ContextualProfiler [here as _profilerPlugin] plugin instantiated previously.

  Future<void> openAccessUsageSettingsDirectly() async {
    String platformVersion;
    try {
      await _profilerPlugin.openUsageAccessSettingsDirectly(blacklist); // - blacklist (Optional) List of device manufacturers for which the usage settings should be avoided. On some devices, especially from certain manufacturers as Xiaomi, a system warning might be displayed when attempting to access the usage settings. To prevent this action on those devices, you can:

      //- Pass `null`: This will apply a default list of manufacturers known to have this issue.
      // - Provide a custom list of manufacturers as an array (`["manufacturer1", "manufacturer2"]`): This will prevent the settings from being accessed only on devices from those specific brands.
      //- Pass an empty array `[]`: This will allow the settings to be accessed on all devices without any restrictions.
      platformVersion = 'opened successfully';
    } on PlatformException {
      platformVersion = 'Failed to open Access Usage Settings.';
    }

    if (!mounted) return;

    setState(() {
      _response = platformVersion;
    });
  }

Send data to Fivvy's analytics service #

This function will allow your app to send the information of each user to the Fivvy Analytic's API. You must add on some view or loading component that can send the data at least 1 time a day.

  Future<void> initContextualDataCollection() async {
    String response;

    ContextualCredential initConfig = ContextualCredential(
        customerId: customerId,
        apiPassword: apiSecret,
        apiUsername: apiKey,
        authApiUrl: authApiUrl,
        sendDataApiUrl: sendDataApiUrl,
        forceInit: BOOLEAN  // Boolean parameter that controls the data submission and collection process. If set to `false`, data will not be re-sent or collected until 24 hours have passed since the last submission. If set to `true`, this condition will be ignored, and data will be sent or collected immediately, regardless of the time elapsed.
        )

    try {
      await _profilerPlugin.initContextualDataCollection(initConfig);
      response = 'Send data successfully';
    } on PlatformException {
      response = 'Something went wrong.';
    }

    if (!mounted) return;

    setState(() {
      this._response = response;
    });
  }
