Troubleshooting Guide

iOS

pod install failing on latest iOS version on or after 17

If you are seeing the following error when trying to build or install pod, then you have to update your cocoapod version. Error: DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS, use TOOLCHAIN_DIR instead

To update the DT_TOOLCHAIN_DIR to TOOLCHAIN_DIR, add below in your podfile,

  installer.aggregate_targets.each do |target|
    target.xcconfigs.each do |variant, xcconfig|
    xcconfig_path = target.client_root + target.xcconfig_relative_path(variant)
    IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
    end
end

  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.base_configuration_reference.is_a? Xcodeproj::Project::Object::PBXFileReference
        xcconfig_path = config.base_configuration_reference.real_path
        IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
      end
  end

Please run the below command to update your cocoapod. brew upgrade cocoapods

Then run pod update with,

pod install --repo-update To install pod manually, follow the below series of commands,

cd ios

rm Podfile.lock

rm -rf Pods

pod cache clean --all

pod deintegrate

pod setup

pod install

If you still encounter similar error, then you have to replace the DT_TOOLCHAIN_DIR with TOOLCHAIN_DIR manually. Go to project search and search for DT_TOOLCHAIN_DIR and replace manually one by one with TOOLCHAIN_DIR.

Android

React-native Android fails to build on mac

If might see the below error while building your React-Native on Android on Mac on or after azure-communication-ui-calling:1.6.0 Error: dlopen: failed to load __emutls_get_address

This error generates in React-Native version 0.69 and if you are using ui library version on or after 1.6.0

This is a common issue from React-Native JNI9 linking error.

You can refer or relate to the issue more here.

Another way you can successfully avoid such issue if you try to build on any other machine except apple's silicon based M1/M2 chipset.

Gradle sync fails

The gradle sync failure depends on the expected minimum gradle version for different React-Native versions. For example, gradle version 0.69, please update the gradle version on the build.gradle of android.

classpath("com.android.tools.build:gradle:7.4.2")

Please update the gradle-wrapper properties as well. For example,

distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip

Also please make sure to update your gradle jdk version to JDK-17 for React-Native 0.69 or later versions.

Android App Build Failure

The native android ./gradlew build command executes successfully but the react-native sample app fails when trying to run on android device. One potentially gets the following error-

Execution failed for task ':app:installDebug'.
> java.util.concurrent.ExecutionException: com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: Connection reset by peer

Potential solutions could be for above scenario are:

• Please check if there is a physical android device connected. To check run adb devices command.
• Restart the adb server. To do so first run kill adb-server then start adb-server.
• Check if there is already a debug application installed in the device. In that case, uninstall the application then run the install or run-android command.
