Solving Android Resource Linking Errors on Lstart A Developer's Guide

Dhruv DaveArticle

Are you encountering resource linking failures on Lstart while developing your Android app in Android Studio? In this tutorial, we provide a comprehensive guide on how to fix this issue. We'll begin by discussing the causes of resource linking errors and the importance of debugging tools. Next, we'll provide step-by-step instructions on how to troubleshoot Lstart errors in Android Studio. We'll also cover the role of the Android build system and Gradle build files in resource linking. By following our best practices, both beginners and experienced developers can solve Android resource linking issues on Lstart and continue building successful apps. Don't let resource linking failures hinder your app development progress - start resolving Lstart errors with our developer's guide today.

Error Detail Info

To give some background: Our project is currently on react native 0.63.2 and previous compileSdkVersion was 30. We were successfully building android app till a few days back but suddenly it started to fail with the following error:

AAPT: error: resource android:attr/lStar not found

AAPT ERROR

After some searching online, we followed some solutions here: Resource linking fails on lStar

Force use this androidx-core version in your app module file build.gradle:

configurations.all {
  resolutionStrategy {
    force 'androidx.core:core:1.6.0'
    force 'androidx.core:core-ktx:1.6.0'
  }
}

We upgraded to compileSdkVersion and targetSdkVersion to 31, did some other related changes and were able to compile successfully. But the app is now crashing immediately on startup when I run it on Android 13 device.

Error Log Info

The following are the error logs from logcat:

lStar Solution

I recommend using fixed stable version of react native library if you are not using one, like below:

  • Optionally, you may consider using dynamic value of REACT_NATIVE_VERSION from your package.json file with the following script:
def REACT_NATIVE_VERSION = new File(['node', '--print',"JSON.parse(require('fs').readFileSync(require.resolve('react-native/package.json'), 'utf-8')).version"].execute(null, rootDir).text.trim())

allprojects {
    configurations.all {
        resolutionStrategy {
            force "com.facebook.react:react-native:" + REACT_NATIVE_VERSION
        }
    }
    repositories {
        google()
        ...
    }
}

Solution

This will prevent your app from unexpected behaviours due to unstable versions, however, downside of this is you have to check for latest updates from react native library manually and update time to time.

Soloader Solution

if you still facing Error of **/**.so plesase add below code in your project build.gradle.

packagingOptions {
        pickFirst "lib/armeabi-v7a/libc++_shared.so"
        pickFirst "lib/arm64-v8a/libc++_shared.so"
        pickFirst "lib/x86/libc++_shared.so"
        pickFirst "lib/x86_64/libc++_shared.so"
    }
