Question

是否有功能或命令来获取Android设备的基本设备配置？像RAM大小，操作系统版本，处理器核心数量等。

Answer 1

您可以获取所有设备信息。希望得到帮助。

获取设备的CPU核心

/**
 * Gets the number of cores available in this device, across all processors.
 * Requires: Ability to peruse the filesystem at "/sys/devices/system/cpu"
 * @return The number of cores, or 1 if failed to get result
 */
private int getNumCores() {
    //Private Class to display only CPU devices in the directory listing
    class CpuFilter implements FileFilter {
        @Override
        public boolean accept(File pathname) {
            //Check if filename is "cpu", followed by a single digit number
            if(Pattern.matches("cpu[0-9]+", pathname.getName())) {
                return true;
            }
            return false;
        }      
    }

    try {
        //Get directory containing CPU info
        File dir = new File("/sys/devices/system/cpu/");
        //Filter to only list the devices we care about
        File[] files = dir.listFiles(new CpuFilter());
        //Return the number of cores (virtual CPU devices)
        return files.length;
    } catch(Exception e) {
        //Default to return 1 core
        return 1;
    }
}

获取设备的总RAM

public static String getTotalRAM() {
    RandomAccessFile reader = null;
    String load = null;
    try {
        reader = new RandomAccessFile("/proc/meminfo", "r");
        load = reader.readLine();
    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        // Streams.close(reader);
    }
    return load;
}

设备的其他信息

String _OSVERSION = System.getProperty("os.version");
String _RELEASE = android.os.Build.VERSION.RELEASE;
String _DEVICE = android.os.Build.DEVICE; 
String _MODEL = android.os.Build.MODEL; 
String _PRODUCT = android.os.Build.PRODUCT; 
String _BRAND = android.os.Build.BRAND; 
String _DISPLAY = android.os.Build.DISPLAY; 
String _CPU_ABI = android.os.Build.CPU_ABI; 
String _CPU_ABI2 = android.os.Build.CPU_ABI2; 
String _UNKNOWN = android.os.Build.UNKNOWN; 
String _HARDWARE = android.os.Build.HARDWARE;
String _ID = android.os.Build.ID; 
String _MANUFACTURER = android.os.Build.MANUFACTURER; 
String _SERIAL = android.os.Build.SERIAL; 
String _USER = android.os.Build.USER; 
String _HOST = android.os.Build.HOST;

Answer 2

您可以从/ proc / cpuinfo文件中获取所需的大部分信息。以下是有关如何加载和解析该文件的教程：How to get Cpu Information on android

有关RAM的信息可以从/ proc / meminfo文件中获取

Answer 3

查看android.os.Build课程。

android.os.Build.HARDWARE
android.os.Build.DEVICE             
android.os.Build.MODEL               
android.os.Build.PRODUCT            
android.os.Build.BOARD        
android.os.Build.DISPLAY

等...

要获取操作系统版本号，您可以尝试

System.getProperty("os.version");

Answer 4

您可以查看android.os.Build以确定手机品牌和型号。从那里开始查找基于品牌和型号的手机规格。
