如何检测系统信息，如操作系统或设备types
我想知道的最重要的事情是设备types，操作系统版本，如果它有一个硬件键盘和可能的屏幕分辨率。 但如果你知道其他有用的debugging信息，请添加他们:)
我发现这个OS版本：
string += "OS Version: " + System.getProperty("os.version"); 我如何获得其他属性？
编辑：为了得到一个有用的属性的完整概述，我把它们组合在我的ErrorHandler活动（开始阅读56行）： https ： //github.com/simon-heinen/SimpleUi/blob/master/SimpleUI/srcAndroid /simpleui/util/DeviceInformation.java#L56
Windowsize和键盘的存在是一个好主意，我添加了一些更多的信息debugging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 + ")";
这里是所有的设备信息，可以在android中使用下面的枚举和工具类
public enum Device { DEVICE_TYPE, DEVICE_SYSTEM_NAME, DEVICE_VERSION, DEVICE_SYSTEM_VERSION, DEVICE_TOKEN, /** * */ DEVICE_NAME, DEVICE_UUID, DEVICE_MANUFACTURE, IPHONE_TYPE, /** * */ CONTACT_ID, DEVICE_LANGUAGE, DEVICE_TIME_ZONE, DEVICE_LOCAL_COUNTRY_CODE, /** * */ DEVICE_CURRENT_YEAR, DEVICE_CURRENT_DATE_TIME, DEVICE_CURRENT_DATE_TIME_ZERO_GMT, /** * */ DEVICE_HARDWARE_MODEL, DEVICE_NUMBER_OF_PROCESSORS, DEVICE_LOCALE, DEVICE_NETWORK, DEVICE_NETWORK_TYPE, /** * */ DEVICE_IP_ADDRESS_IPV4, DEVICE_IP_ADDRESS_IPV6, DEVICE_MAC_ADDRESS, DEVICE_TOTAL_CPU_USAGE, /** * */ DEVICE_TOTAL_MEMORY, DEVICE_FREE_MEMORY, DEVICE_USED_MEMORY, /** * */ DEVICE_TOTAL_CPU_USAGE_USER, DEVICE_TOTAL_CPU_USAGE_SYSTEM, /** * */ DEVICE_TOTAL_CPU_IDLE, DEVICE_IN_INCH; }

屏幕分辨率：
getWindow().getWindowManager().getDefaultDisplay().getWidth(); getWindow().getWindowManager().getDefaultDisplay().getHeight();
对于硬件键盘的存在：
boolean keyboardPresent = (getResources().getConfiguration().keyboard != Configuration.KEYBOARD_NOKEYS);

屏幕分辨率更新：getHeight（）和getWidth在API级别13中弃用 – HONEYCOMB_MR2; 使用getSize（Point）来代替。 更多信息： http : //developer.android.com/reference/android/view/Display.html
试试这个来获取设备信息。
String serviceType = Context.TELEPHONY_SERVICE; TelephonyManager m_telephonyManager = (TelephonyManager) getActivity().getSystemService(serviceType); String DeviceId, SubscriberId, NetworkOperator, OsVersion,SimOperatorName; DeviceId = m_telephonyManager.getDeviceId(); SubscriberId = m_telephonyManager.getSubscriberId(); NetworkOperator = m_telephonyManager.getNetworkOperator(); OsVersion = m_telephonyManager.getDeviceSoftwareVersion(); SimOperatorName = m_telephonyManager.getSimOperatorName();
显示输出
Log.d("Device Information :", "\n DeviceId : " + DeviceId + "\n SubscriberId : " + SubscriberId + "\n NetworkOperator : " + NetworkOperator + "\n SoftwareVersion : " + OsVersion+ "\n SimOperatorName : " + SimOperatorName);
