Автозапуск на Eddystone-UID в пределах 1 метра

Question

Я хочу автоматически запускать свою деятельность, когда маячок находится в пределах 1 метра. Этот вопрос был posed before, но я не могу заставить мой работать, используя/изменяя его код.

Как и этот пост, я выполнил те же шаги с помощью библиотеки маяков android через altbeacon github, но все еще не увенчался успехом.

У меня также есть "compile" org.altbeacon: android-beacon-library: 2.7+ '"в файле build.gradle.

Answer 1

Несколько советов:

1. Попробуйте добавить строку отладки Log.d("Distance:"+beacon.get Distance());, прежде чем вы установите флажок для расстояния < 1. Затем запустите приложение, наблюдая за выходом LogCat, который ищет эту строку журнала.

2. Поймите, что если у вас есть Android 4.x, это может занять до пяти минут, чтобы обнаружить в фоновом режиме.

3. Всегда проще сначала получать приложения, работающие на переднем плане, а затем добавлять возможности фона. Убедитесь, что вы можете написать код, чтобы определить ваш маяк на переднем плане.

С помощью кода davidgyoung размещенного на github, я был в состоянии решить эту проблему.
