如何在 Android 设备上获取系统信息375
Android 操作系统为开发者提供了丰富的 API 和工具,用于获取有关设备系统和配置的重要信息。以下是有关如何从 Android 设备获取系统信息的详细指南:
获取 Android 版本:
String androidVersion = ;
获取设备型号:
String deviceModel = ;
获取制造商:
String manufacturer = ;
获取 API 级别:
int apiLevel = .SDK_INT;
获取处理器架构:
String processorArchitecture = Build.CPU_ABI;
获取屏幕分辨率:
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int screenWidth = ;
int screenHeight = ;
获取电池信息:
Intent batteryIntent = registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
int batteryLevel = (BatteryManager.EXTRA_LEVEL, -1);
int batteryScale = (BatteryManager.EXTRA_SCALE, -1);
int batteryPercentage = batteryLevel / batteryScale * 100;
获取网络连接信息:
ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = ();
if (activeNetworkInfo != null) {
String networkType = ();
String networkSubtype = ();
}
获取可用内存:
ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
memoryInfo = new ();
(memoryInfo);
long availableMemory = ;
获取安装的应用程序:
PackageManager packageManager = getPackageManager();
List installedPackages = (0);
for (PackageInfo packageInfo : installedPackages) {
String packageName = ;
String appName = (packageManager).toString();
}
获取系统属性:
String systemProperty = (".lib2");
通过遵循这些指南,开发者可以轻松地从 Android 设备收集广泛的系统信息,从而帮助他们在应用程序中做出明智的决策并优化用户体验。
