Android uygulamalarında Gemini API'yi kullanmaya başlama (istemci SDK'sı)

Kotlin

// Access your API key as a Build Configuration variable
val apiKey = BuildConfig.apiKey

Java

// Access your API key as a Build Configuration variable
String apiKey = BuildConfig.apiKey;

Kotlin

val generativeModel = GenerativeModel(
    // Use a model that's applicable for your use case (see "Implement basic use cases" below)
    modelName = "MODEL_NAME",
    // Access your API key as a Build Configuration variable (see "Set up your API key" above)
    apiKey = BuildConfig.apiKey
)

Java

Java için GenerativeModelFutures nesnesini başlatmanız da gerekir.

// Use a model that's applicable for your use case (see "Implement basic use cases" below)
GenerativeModel gm = new GenerativeModel(/* modelName */ "MODEL_NAME",
// Access your API key as a Build Configuration variable (see "Set up your API key" above)
    /* apiKey */ BuildConfig.apiKey);

// Use the GenerativeModelFutures Java compatibility layer which offers
// support for ListenableFuture and Publisher APIs
GenerativeModelFutures model = GenerativeModelFutures.from(gm);

Kotlin

generateContent() işlevinin bir askıya alma işlevi olduğunu ve Coroutine kapsamından çağrılması gerektiğini unutmayın. Coroutines hakkında bilginiz yoksa Android'de Kotlin Coroutines makalesini okuyun.

val generativeModel = GenerativeModel(
    // For text-only input, use the gemini-pro model
    modelName = "gemini-pro",
    // Access your API key as a Build Configuration variable (see "Set up your API key" above)
    apiKey = BuildConfig.apiKey
)

val prompt = "Write a story about a magic backpack."
val response = generativeModel.generateContent(prompt)
print(response.text)

Java

generateContent() işlevinin bir ListenableFuture döndürdüğünü unutmayın. Bu API hakkında bilginiz yoksa ListenableFuture kullanma hakkındaki Android belgelerine bakın.

// For text-only input, use the gemini-pro model
GenerativeModel gm = new GenerativeModel(/* modelName */ "gemini-pro",
// Access your API key as a Build Configuration variable (see "Set up your API key" above)
    /* apiKey */ BuildConfig.apiKey);
GenerativeModelFutures model = GenerativeModelFutures.from(gm);

Content content = new Content.Builder()
    .addText("Write a story about a magic backpack.")
    .build();

Executor executor = // ...

ListenableFuture<GenerateContentResponse> response = model.generateContent(content);

    @Override
    public void onSuccess(GenerateContentResponse result) {
