این صفحه نمونه برنامه ای را ارائه می دهد که نحوه تهیه یک دستگاه اختصاصی را نشان می دهد و دستور راه اندازی مجدد برای آن ارسال می کند. این برنامه از کتابخانه سرویس گیرنده جاوا API مدیریت Android استفاده می کند.
قبل از شروع
- کتابخانه Java Client API مدیریت Android را دانلود کنید و تمام فایل‌های jar را به مسیر کلاس اضافه کنید.
- یک پروژه Google Cloud ایجاد یا انتخاب کنید که مالک شرکت ایجاد شده باشد.
- Android Management API را در پروژه فعال کنید.
- یک حساب سرویس ایجاد یا انتخاب کنید که دارای نقش مالک یا ویرایشگر در پروژه باشد.
- یک حساب Google برای ثبت نام در یک شرکت جدید انتخاب کنید. این حساب نمی‌تواند سرپرست هیچ شرکتی از قبل موجود باشد.
- ثابت های
PROJECT_IDوSERVICE_ACCOUNT_CREDENTIAL_FILEرا در نمونه کد تنظیم کنید. - برای نصب برنامه مورد نظر خود، ثابت
APP_PACKAGE_NAMEدر نمونه کد تغییر دهید.
