بدء استخدام Gemini API في تطبيقات Android (حزمة تطوير البرامج (SDK) للعميل)

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

بالنسبة إلى لغة Java، عليك أيضًا إعداد الكائن GenerativeModelFutures.

// 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);

تجدر الإشارة إلى أن generateContent() هي دالة تعليق ويجب استدعاؤها من نطاق الكوروتين. إذا لم تكن معتادًا على استخدام الكوروتينات (الكوروتينات)، يمكنك قراءة كوروتيني كوتلين على Android.

val prompt = "Write a story about a magic backpack."
