tentei rodar o projeto via usb com um aparelho android no ubuntu, mas não deu, segue a mensagem de erro:

Olá Nícolas, tudo bem?

Esse erro ocorre porque o comando react-native run-android não consegue encontrar a sua instalação do SDK do Android. Ele está procurando por uma variável de ambiente chamada ANDROID_HOME que aponta para a pasta raiz do SDK. Para corrigir esse erro, você precisa definir essa variável de ambiente.

Uma maneira de fazer isso é editar o arquivo ~/.bashrc no seu terminal e adicionar a seguinte linha:

export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
Mude o caminho para o local onde você instalou o seu SDK do android, depois execute

source ~/.bashrc

Outra alternativa é incluir o caminho do sdk no arquivo android/local.properties

sdk.dir = /caminho/para/sdk

Depois de fazer isso, você deve ser capaz de executar o comando react-native run-android sem problemas e seu aplicativo será instalado no dispositivo conectado via USB. Certifique-se de ter configurado as configurações de desenvolvimento no seu dispositivo Android também.

Se você continuar tendo problemas, tente executar o comando ./gradlew app:installDebug diretamente na pasta android do seu projeto. isso também pode ajudar a identificar qualquer problema adicional com sua configuração do Gradle.
