برنامج تعليمي: بدء استخدام Gemini API

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(
    // The Gemini 1.5 models are versatile and work with most use cases
    modelName = "gemini-1.5-flash",
    // Access your API key as a Build Configuration variable (see "Set up your API key" above)
    apiKey = BuildConfig.apiKey

Java

في لغة Java، يجب أيضًا إعداد الكائن GenerativeModelFutures.

// Use a model that's applicable for your use case
// The Gemini 1.5 models are versatile and work with most use cases
GenerativeModel gm = new GenerativeModel(/* modelName */ "gemini-1.5-flash",
// 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);

يُرجى العلم أنّ generateContent() هي دالة تعليق ويجب استدعاؤها من نطاق Coroutine. إذا لم تكن معتادًا على استخدام الكوروتينات، يمكنك الاطّلاع على Kotlin Coroutines على Android.
