So now you know the popular tools to integrate Machine Learning in Android apps, but how to integrate it?

Let’s jump on to the tutorial to apply ML in the Android app…

How To Deploy Machine Learning Model In Android Apps?

Appling ML into an Android app is quite simple but requires hiring a Machine learning developer in India who can handle the project’s complexity. Integrating machine learning in an Android app involves several steps. 

So if you are all set to take your Android app to the next level, you need to check out this simple step-by-step guide to integrate Machine Learning in Android app, along with code commands and explanations for each step:

Step 1: Set up the Android Development Environment

To begin, make sure you have Android Studio installed on your machine. Android Studio provides a comprehensive development environment for building Android apps.

Step 2: Create a New Android Project

Open Android Studio and create a new Android project. Choose a suitable project name, package name, and minimum SDK version based on your requirements.

Step 3: Add Required Dependencies

In your app-level build.gradle file, add the necessary dependencies for machine learning. One popular library is TensorFlow Lite, which provides tools and models for running machine learning on Android devices. 

Add the following lines to your dependencies block:

implementation ‘org.tensorflow:tensorflow-lite:2.5.0’

implementation ‘org.tensorflow:tensorflow-lite-support:0.1.0’

Step 4: Prepare Your Machine Learning Model

Before integrating your machine learning model into the Android app, you need to convert it into a format compatible with TensorFlow Lite. 

Typically, models are trained using frameworks like TensorFlow or PyTorch. Once you have a trained model, convert it to the TensorFlow Lite format using the TensorFlow Lite Converter.

Here’s an example command to convert a TensorFlow model to TensorFlow Lite:

tensorflow.lite.TocoConverter \

  –input_model=my_model.pb \

  –output_file=my_model.tflite \

  –input_format=TENSORFLOW_GRAPHDEF \

  –output_format=TFLITE \

  –inference_type=FLOAT \

  –input_type=FLOAT \

  –input_arrays=input \

  –output_arrays=output

Step 5: Include the Model in the Android Project

Copy the converted TensorFlow Lite model (e.g., my_model.tflite) into the app’s assets folder. This folder contains static files bundled with the app.

Step 6: Load and Run the Model in the Android App

Now, it’s time to write the code to load and run the machine learning model in your Android app. 

Create a new Java or Kotlin class and add the following code:

import org.tensorflow.lite.Interpreter;

import java.nio.MappedByteBuffer;

import java.io.FileInputStream;

import java.nio.channels.FileChannel;

public class MLModelExecutor {

    private Interpreter tfliteInterpreter;

    public MLModelExecutor() {

        try {

            // Load the TensorFlow Lite model

            MappedByteBuffer modelFile = loadModelFile();

            tfliteInterpreter = new Interpreter(modelFile);

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

    private MappedByteBuffer loadModelFile() throws Exception {

        FileInputStream fileInputStream = new FileInputStream(“path/to/your/model.tflite”);

        FileChannel fileChannel = fileInputStream.getChannel();

        long startOffset = 0;

        long declaredLength = fileChannel.size();

        return fileChannel.map(FileChannel.MapMode.READ_ONLY, startOffset, declaredLength);

    }

    public float[] runInference(float[] inputData) {

        // Prepare input and output arrays

        float[][] input = new float[1][inputData.length];

        input[0] = inputData;

        float[][] output = new float[1][numOutputClasses];

        // Run the inference

        tfliteInterpreter.run(input, output);

        // Return the output

        return output[0];

    }

}

In the above code, the loadModelFile() function loads the TensorFlow Lite model file into a MappedByteBuffer, and runInference() performs the actual inference using the loaded model.

Step 7: Integrate the MLModelExecutor into Your App

To use the MLModelExecutor class in your app, create an instance of it and call the runInference() method with your input data. You can then process the output as per your application’s requirements.

That’s it! You have finally integrated machine learning into your Android app using TensorFlow Lite!

However, this is the most general way of adding Machine Learning in Android apps. We have explained the overview of ML integration in Android apps in basic steps that help businesses and developers understand how simple it is. But depending on your specific requirements and the machine learning framework you’re using, there may be additional steps or variations in the implementation.
