如何检测系统信息，如操作系统或设备类型

小开

屏幕分辨率:

getWindow().getWindowManager().getDefaultDisplay().getWidth();
getWindow().getWindowManager().getDefaultDisplay().getHeight();

对于硬件键盘:

boolean keyboardPresent = (getResources().getConfiguration().keyboard != Configuration.KEYBOARD_NOKEYS);

最佳答案

Edit: 为了获得有用属性的完整概述，我在 ErrorHandler 活动中将它们组合在一起(从第56行开始阅读) : https://github.com/simon-heinen/SimpleUi/blob/master/SimpleUI/srcAndroid/simpleui/util/DeviceInformation.java#L56

窗口大小和键盘的存在是一个好主意，我添加了一些更多的信息用于调试目的:

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 + ")";

屏幕分辨率更新: GetHeight ()和 getWidth 在 API 级别13-HONEYCOMB _ MR2中不推荐使用; 改为使用 getSize (Point)。更多信息请访问: Http://developer.android.com/reference/android/view/display.html

OsVersion = m_telephonyManager.getDeviceSoftwareVersion();

显示输出
