Esta página descreve como gerar uma biblioteca de cliente a partir de sua API de back-end do Python (o código executado no servidor). Qualquer aplicativo para Java ou Android pode usar essa biblioteca para chamar a API.

Any Java or Android app can use this\nlibrary to call the API.\n\nTo create iOS clients for your API, we recommend that you use\n[Google APIs Objective-C Client Library for REST APIs](https://github.com/google/google-api-objectivec-client-for-rest/wiki).\n\nBefore you begin\n----------------\n\n- Download the Cloud Endpoints Frameworks library and tools into your app directory as described in [Getting started with Endpoints Frameworks](/endpoints/docs/frameworks/python/quickstart-frameworks-python).\n- Make sure you have properly [decorated](/endpoints/docs/frameworks/python/create_api) your API code with the expected frameworks code.\n\nGenerating the client library\n-----------------------------\n\nThe following instructions demonstrate how to use the\nEndpoints Frameworks\n[command-line\ntool](/endpoints/docs/frameworks/python/endpoints_tool) to generate a Gradle client bundle from the sample code from\n[Getting started with Cloud Endpoints](/endpoints/docs/frameworks/python/quickstart-frameworks-python).\n\nTo generate a client library:\n\n1. Change directory to the directory containing your API `app.yaml` file and\n API classes.\n\n2. Run the Endpoints command-line tool similar to the following:\n\n python lib/endpoints/endpointscfg.py get_client_lib java -bs gradle main.EchoApi\n\n where `main` is the class containing your API and `EchoApi` is your API name.\n\n Wait for the tool to generate the library; on success the tool displays a\n message similar to this one: \n\n ```\n API client library written to ./echo-v1.zip\n ```\n3. Unzip the file using the unzip utility, or use another ZIP-compatible\n unarchiving utility:\n\n unzip ./echo-v1-java.zip\n\n4. Change directory:\n\n cd echo\n\n5. Build the client library:\n\n gradle build\n\n The output is in the `build/libs` directory. The exact filename depends\n on the version of the client. It is similar to\n `echo-v1-1.23.0-SNAPSHOT.jar`.\n6. Add the client library JAR to your app.\n\n7. Repeat these steps every time you modify your API code.\n\nWhat's next\n-----------\n\nFor information and sample code showing how to access a backend API from a\nPython client, see\n[Accessing backend APIs from Python clients](/endpoints/docs/frameworks/python/access_from_python)."]]
