Я хочу создать свою собственную клавиатуру emoji в Android. Пользователь должен иметь возможность выбрать эту клавиатуру в качестве метода ввода для своего телефона Android.
Я попытался создать ее, и я могу использовать ее в своем приложении, но я понятия не имею, как сделать это в качестве метода ввода, чтобы эта клавиатура была доступна для всех других приложений в моем телефоне. Я где-то читал, что мне нужно создать для этого службу, чтобы она связывалась со службой ввода. Кроме этого, я не могу понять остальное.
Вот что я сделал. Хотя это отличается от того, что я хочу сделать, но это только начало, и я не знаю, как действовать дальше.
