Kivy Launcher сразу падает, фильтрация logcat?

1 голос
/ 11 марта 2019

Я пытаюсь получить приложение, которое я сделал, для запуска на моем телефоне Android. Приложение отлично работает на моем MacBook. Я использовал только модули, предустановленные с python или kivy, но приложение вылетает сразу после того, как на загрузчике kivy появляется значок загрузки. Поэтому я немного покопался и обнаружил, что могу проверить журналы, разблокировав опции разработчика на моем телефоне и используя logcat, но проблема в том, что logcat просто выплевывает много информации, чтобы я мог ее проанализировать.

Есть ли способ отфильтровать logcat, чтобы поднять журналы специально для kivy launcher? Я проверил все, и все говорят, что вы можете отфильтровать его по имени приложения, но я пробовал несколько вариантов

adb logcat "application_or_tag_name: " ": S"

напр .: adb logcat "Kivy_Launcher: " ": S" adb logcat "kivy_launcher: " ": S" adb logcat "Kivy Launcher: " ": S"

но ни один из них, похоже, не работает. Я прочитал эти ссылки:

https://logmatic.io/blog/a-how-to-guide-to-debugging-with-android-logcat/ https://developer.android.com/studio/command-line/logcat

Мне удалось получить некоторые из журналов через Android Studio, но я не уверен, предназначены ли эти журналы для «нового приложения», которое мне пришлось создать для запуска программы, или они действительно являются журналами с моего телефона, когда Я запускаю Kivy Launcher. Вот они:
