Are you tired of dealing with unnecessary dependencies in your Android app? Do you want to streamline your project and improve performance? Look no further! In this article, we’ll show you how to exclude the drawable of unnecessary devices such as LDTR/LWatch brought in by androidx.appcompat:appcompat
through Gradle configuration. By the end of this tutorial, you’ll be able to optimize your app and take control of your dependencies.
What are unnecessary dependencies?
Unnecessary dependencies are libraries or modules that are included in your project but not actually used. These dependencies can cause a range of issues, including:
- Bloated APK size
- Performance degradation
- Conflicting versions
- Increased build times
In this article, we’ll focus on excluding the LDTR/LWatch drawable, which is brought in by androidx.appcompat:appcompat
. This dependency is often included by default in many Android projects, but it’s not always necessary.
Why exclude LDTR/LWatch?
LDTR/LWatch is a wearable device-specific drawable that’s included in the androidx.appcompat:appcompat
library. If your app doesn’t support wearable devices, there’s no need to include this dependency. By excluding it, you can:
- Reduce APK size
- Improve performance
- Simplify your project structure
How to exclude LDTR/LWatch with Gradle configuration
To exclude the LDTR/LWatch drawable, you’ll need to modify your Gradle configuration files. Here’s a step-by-step guide:
Step 1: Identify the dependency
Open your project’s build.gradle
file and look for the following line:
implementation 'androidx.appcompat:appcompat:1.2.0'
This line includes the entire androidx.appcompat:appcompat
library, which includes the LDTR/LWatch drawable.
Step 2: Exclude the drawable
To exclude the LDTR/LWatch drawable, add the following code to your build.gradle
file:
android {
...
defaultConfig {
...
vectorDrawables.useSupportLibrary = true
packagingOptions {
exclude 'ldtrl/**'
exclude 'ldtrw/**'
}
}
...
}
This code tells Gradle to exclude the LDTR/LWatch drawable from the APK.
Step 3: Verify the exclusion
After modifying your Gradle configuration, run the following command in your terminal:
./gradlew assembleDebug
This command will rebuild your APK. Check the APK file size and contents to verify that the LDTR/LWatch drawable has been excluded.
Tips and Variations
Here are some additional tips and variations to help you optimize your Android app:
Exclude other unnecessary dependencies
Take a closer look at your project’s dependencies and identify any unnecessary libraries or modules. You can exclude these dependencies using similar techniques to the one described above.
Use ProGuard or R8
ProGuard and R8 are powerful tools that can help you optimize your app’s code and reduce APK size. Consider using these tools in conjunction with Gradle configuration to further streamline your project.
Use Android Studio’s built-in features
Android Studio provides a range of built-in features to help you optimize your app, including code analysis and APK analysis tools. Take advantage of these features to identify areas for improvement.
Conclusion
In this article, we’ve shown you how to exclude the LDTR/LWatch drawable brought in by androidx.appcompat:appcompat
through Gradle configuration. By following these steps, you can optimize your Android app and take control of your dependencies. Remember to regularly review your project’s dependencies and exclude any unnecessary libraries or modules to ensure your app is running at its best.
Dependency | Reason to exclude |
---|---|
LDTR/LWatch | Unnecessary for non-wearable devices |
Other unnecessary libraries | Bloating APK size and degrading performance |
Happy coding, and don’t forget to optimize your Android app!

Frequently Asked Question
Get the answers to the most commonly asked questions about excluding the drawable of unnecessary devices brought in by androidx.appcompat:appcompat through Gradle configuration.
What is the purpose of excluding the drawable of unnecessary devices?
Excluding the drawable of unnecessary devices helps to reduce the APK size, improve app performance, and prevent unnecessary resources from being packaged. By excluding these drawables, you can ensure that your app only includes the resources it actually needs, resulting in a more efficient and optimized app.
How do I identify the unnecessary devices brought in by androidx.appcompat:appcompat?
You can identify the unnecessary devices by analyzing the AndroidManifest.xml file and the app’s resource folder. Look for devices that are not compatible with your app’s minimum SDK version or devices that are not compatible with your app’s targeted architecture. You can also use tools like Android Studio’s “Android Device Manager” to identify the devices that are not necessary for your app.
What is the impact of not excluding the drawable of unnecessary devices on my app’s performance?
Not excluding the drawable of unnecessary devices can lead to increased APK size, slower app loading times, and increased memory usage. This can result in a poor user experience, negative reviews, and even app crashes. By excluding these unnecessary devices, you can ensure that your app is optimized for performance and provides a better user experience.
How do I exclude the drawable of unnecessary devices through Gradle configuration?
You can exclude the drawable of unnecessary devices by adding the following code to your build.gradle file: `android { defaultConfig { resConfigs “nodpi”, “hdpi”, “xhdpi”, “xxhdpi”, “xxxhdpi” } }`. This code tells Gradle to only include the drawables for the specified densities, excluding the unnecessary devices.
What are the benefits of excluding the drawable of unnecessary devices in terms of APK size reduction?
Excluding the drawable of unnecessary devices can significantly reduce the APK size, making it easier to distribute and install. A smaller APK size also means faster download times, reduced data consumption, and improved overall app performance. Additionally, a smaller APK size can also lead to improved app store ratings and reviews, as users are more likely to download and install smaller apps.
