Intelligent Mobile Projects with TensorFlow

Overview of this book

As a developer, you always need to keep an eye out and be ready for what will be trending soon, while also focusing on what's trending currently. So, what's better than learning about the integration of the best of both worlds, the present and the future? Artificial Intelligence (AI) is widely regarded as the next big thing after mobile, and Google's TensorFlow is the leading open source machine learning framework, the hottest branch of AI. This book covers more than 10 complete iOS, Android, and Raspberry Pi apps powered by TensorFlow and built from scratch, running all kinds of cool TensorFlow models offline on-device: from computer vision, speech and language processing to generative adversarial networks and AlphaZero-like deep reinforcement learning. You’ll learn how to use or retrain existing TensorFlow models, build your own models, and develop intelligent mobile apps running those TensorFlow models. You'll learn how to quickly build such apps with step-by-step tutorials and how to avoid many pitfalls in the process with lots of hard-earned troubleshooting tips.

Using the image captioning model in Android

Following the same simplicity considerations, we'll develop a new Android app with a minimal UI and focus on how to use the model in Android:

  1. Create a new Android app called Image2Text, add compile 'org.tensorflow:tensorflow-android:+' to the end of your app build.gradle file's dependencies, create an assets folder, and drag and drop to it the image2text_frozen_transformed.pb model file, the word_counts.txt file, and a few test image files.
  2. Add an ImageView and a button to the activity_main.xml file:
<ImageView
android:id="@+id/imageview"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintLeft_toLeftOf="parent...
