اندروید به توسعه دهندگان اجازه می‌دهد تا مجوزهای خود را ساخته و آنها را اجرا کنند. همانند مجوزهای سیستمی که پلتفرم آنها را بررسی می‌کند، شما باید خواص و برچسب‌های مورد نیاز را در فایل AndroidManifest.xml اعلام کنید. اگر برنامه‌ای می‌نویسید که یک نوعِ خاص از قابلیت دسترسی توسط توسعه دهندگان را فراهم می‌کند، شما می‌توانید برای حفاظت از توابع با مجوزهای سفارشی خود، مانع دسترسی‌های غیرمجاز شوید. به کدی که در فایل AndroidMainfest درج شده دقت نمایید:

Bootstrap 4 در واقع یک اقدام بزرگ بود که پس از یک سال توسعه، بزرگی این اقدام در خط به خط کدها احساس می‌گردد. تصمیم گرفتیم تا نسخه‌ی اولیه‌ی آن را به اشتراک بگذاریم و انتقادات و پیشنهادات شما را بشنویم. برای بهبود و پیشرفت در این زمینه، بسیاری از اخبار مرتبط را در اختیار شما قرار می‌دهیم. امیدواریم که ما را در بهتر شدن یاری کنید.
