LEARN WITH A CLEAR DIRECTION

Building Multimodal Android Apps

Combine camera, images, audio and text with explicit consent, media preprocessing, typed output and modality-specific evaluation.

Intermediate to AdvancedSelf-paced7 modules13 available lessons

Your path, one skill at a time.

Combine camera, images, audio and text with explicit consent, media preprocessing, typed output and modality-specific evaluation. Follow six teaching modules, each with a practical assignment, then combine the skills in the final project. Start with the introduction even if the tools are familiar: it defines the scope and boundaries of the path.

Self-paced. Complete each exercise and use its checkpoint before moving to the next module. Revisit any prerequisite you cannot yet demonstrate.

What you’ll learn

  • Preserve image orientation and bound upload size
  • Handle denied permissions and unsupported media
  • Evaluate factual grounding and let the user correct generated fields

01MODULE 01What multimodal AI means2 lessons · Self-paced
  • Modalities and tasks
  • Joint interpretation
  • Perception limits

Understand how different input types contribute evidence.

  1. 01What multimodal AI meansLesson · Self-paced
  2. 02Practice: What multimodal AI meansLab · Self-paced

Ready to move on when: Your output does not present unsupported inference as an observed fact.

02MODULE 02Capture, selection and permissions2 lessons · Self-paced
  • User-selected input
  • Camera lifecycle
  • Preview and consent

Give users control over the media they share.

  1. 01Capture, selection and permissionsLesson · Self-paced
  2. 02Practice: Capture, selection and permissionsLab · Self-paced

Ready to move on when: No image is sent merely because the picker returned it.

03MODULE 03Image preparation and transport2 lessons · Self-paced
  • Orientation and scaling
  • Encoding and size
  • Privacy cleanup

Convert media without losing meaning or overwhelming the request.

  1. 01Image preparation and transportLesson · Self-paced
  2. 02Practice: Image preparation and transportLab · Self-paced

Ready to move on when: Your adapter receives a supported, bounded and correctly oriented input.

04MODULE 04Audio and video context2 lessons · Self-paced
  • Audio preparation
  • Video sampling
  • Timestamps and freshness

Control temporal information and resource use.

  1. 01Audio and video contextLesson · Self-paced
  2. 02Practice: Audio and video contextLab · Self-paced

Ready to move on when: Asynchronous media processing cannot attach evidence to the wrong note.

05MODULE 05Structured results and correction2 lessons · Self-paced
  • Output schema
  • Cross-field validation
  • Correction workflow

Turn multimodal interpretation into editable application data.

  1. 01Structured results and correctionLesson · Self-paced
  2. 02Practice: Structured results and correctionLab · Self-paced

Ready to move on when: Generated fields are not treated as confirmed records before review.

06MODULE 06Evaluation across modalities2 lessons · Self-paced
  • Dataset variation
  • Failure categories
  • Operational budget

Measure the errors specific to each input type.

  1. 01Evaluation across modalitiesLesson · Self-paced
  2. 02Practice: Evaluation across modalitiesLab · Self-paced

Ready to move on when: You can attribute the main errors to the correct part of the pipeline.

07MODULE 07Capstone and portfolio review1 lessons · Self-paced
  • Preserve image orientation and bound upload size
  • Handle denied permissions and unsupported media
  • Evaluate factual grounding and let the user correct generated fields

Build a visual field-note assistant that accepts a user-selected photo and optional dictated context, then produces an editable structured note.

  1. 01Capstone: Building Multimodal Android AppsProject · Self-paced

Ready to move on when: Demonstrate every acceptance criterion and explain the tradeoffs without relying on the lesson text.

PROVE YOUR SKILLS

A portfolio you can build, explain, and defend.

  • Preserve image orientation and bound upload size
  • Handle denied permissions and unsupported media
  • Evaluate factual grounding and let the user correct generated fields

Use the final review rubric to identify gaps. Lesson completion tracks study progress; readiness comes from independently demonstrating the work.
