В настоящее время я разрабатываю для android с использованием eclipse. Я недавно столкнулся с проблемой, когда мое приложение больше не запускается, и оно просто сработает, когда оно открыто.Eclipse - Android-приложение падает при запуске?
Я думаю, что проблема может заключаться в файле макета или в файле activity_main.

Большое спасибо за вашу помощь, я искал уже несколько дней в настоящее время, и не может отследить проблему.
Какие сообщения об ошибках вы получаете в своем выходном файле logcat? Предоставьте нам дополнительную информацию: – MoRe
Я не вижу никаких изменений, отображающих сообщение об ошибке ... В eclipse перейдите в Window-> Show View-> Other-> LogCat. Когда вы запускаете приложение для Android, должен появиться фильтр, отображающий только сообщения из вашего приложения (или вы вдруг заметили кучу красных сообщений об ошибках). – MoRe
Упс! Я только что заметил, что я загрузил неправильный код для своего основного класса активности, теперь он исправлен, хотя – pattyd
