OSやデバイスタイプなどのシステム情報を検出する方法
私が知りたい最も重要なことは、デバイスの種類、OSのバージョン、ハードウェアキーボードが搭載されている場合は、画面の解像度です。しかし、他の有用なデバッグ情報を知っている場合は追加してください:)
OSバージョンでこれを見つけました。
string += "OS Version: " + System.getProperty("os.version");
他のプロパティを取得するにはどうすればよいですか？
編集：有用な属性の完全な概要を取得するために、ErrorHandlerアクティビティでそれらをすべて組み合わせました（56行目から読み始めます）： https://github.com/simon-heinen/SimpleUi/blob/master /SimpleUI/srcAndroid/simpleui/util/DeviceInformation.Java#L56
Windowsizeとキーボードの存在は良いアイデアでした。デバッグのためにいくつかの情報を追加しました。
String s="Debug-infos:";
s += "\n OS Version: " + System.getProperty("os.version") + "(" + Android.os.Build.VERSION.INCREMENTAL + ")";
s += "\n OS API Level: " + Android.os.Build.VERSION.SDK_INT;
s += "\n Device: " + Android.os.Build.DEVICE;
s += "\n Model (and Product): " + Android.os.Build.MODEL + " ("+ Android.os.Build.PRODUCT + ")";
以下は、Android以下の列挙型とユーティリティクラスを使用して可能になるすべてのデバイス情報です。
public enum Device {
DEVICE_TYPE, DEVICE_SYSTEM_NAME, DEVICE_VERSION, DEVICE_SYSTEM_VERSION, DEVICE_TOKEN,
