How to Use Realm with Android UI Components

Dec 29, 2021 | Programming

Welcome to your guide on utilizing **Realm**, a mobile database designed to run seamlessly on phones, tablets, and wearables. In this article, we’ll walk you through integrating Realm with Android UI components like ListView and RecyclerView and ensure you hit no roadblocks while doing so!

Getting Started

Before diving into the integration, keep in mind that this library works in conjunction with Realm Java. To set it up correctly, follow these steps:

1. Install Realm Java

Refer to the detailed instructions on the Realm documentation for how to add Realm to your project.

2. Add Adapters to Your Project

To include the Realm adapters, add the following lines to your app’s dependencies:

repositories {
    jcenter()
}
dependencies {
    compile io.realm:android-adapters:3.1.0
}

This library is only compatible with Realm Java versions 3.0.0 and above.

Documentation and Getting Help

For further assistance, the documentation is available at realm.io/docs/java, with the API reference located at realm.io/docs/java/api.

Need Help?

  • If you need help with your code, check for previous questions on the #realm tag or feel free to ask a new question.
  • To report a bug, please open an issue with your Realm version, a full log, the Realm file, and a demo project if possible.
  • If you have a feature request, you can also open an issue detailing the requested functionality.

Using Snapshots

If you’re itching to try out recent bug fixes or features not yet in an official release, use a **-SNAPSHOT** version via Gradle:

repositories {
    maven {
        url "http://oss.jfrog.org/artifactory/oss-snapshot-local"
    }
}
dependencies {
    compile io.realm:android-adapters:version
}

Refer to version.txt for the latest version number.

Building Realm Android Adapters

If you wish to compile the library from the source, make sure you have the following prerequisites:

  • Download and install the JDK 7 or JDK 8.
  • Install the Android SDK, specifically **Android 7.1 (API 25)**.

Once you’ve completed the prerequisites, a simple command will get you going:

./gradlew assemble

This generates an AAR file for the adapter library located at adapters/build/outputs/aar/android-adapters-release.aar.

Troubleshooting

If you encounter any issues along the way, here are some troubleshooting ideas:

  • Double-check your Gradle file to ensure that the Realm version is compatible.
  • Clear your Gradle cache using ./gradlew clean and try building again.
  • Ensure that the Android SDK and the JDK are properly installed and configured.
