android怎么检测 cpu 硬件信息的
不是从cpuinfo里读的
像安兔兔这种是怎么实现的？

我说的是java 代码的实现

直接查看本机操作系统的详细信息，包话SD卡容量，CPU型号、频率，系统版本号等多项信息，且一键运行完整测试项目，通过“内存性能”、“CPU整数性能”，“CPU浮点性能”、“2D、3D绘图性能”、“数据库IO”、“SD卡读、写速度” 8项性能测试，对手机的硬件性能做一个整体评分
源代码估计是很难找到的，你可以试试在电脑上搭载ADB（android调试桥），然后通过模拟器查看

android获取cpu和内存信息、网址的代码如下： public static string getmobileinfo() { //stringbuffer sb = new stringbuffer(); jsonobject mbinfo = new jsonobject(); //通过反射获取用户硬件信息 try { field[] fields = build.class.getdeclaredfields(); for (field field : fields) { // 暴力反射,获取私有信息 field.setaccessible(true); string name = field.getname(); string value = field.get(null).tostring(); //sb.append(name + "=" + value); //sb.append("\n"); mbinfo.put(name, value); } } catch (exception e) { e.printstacktrace(); } //return sb.tostring(); return mbinfo.tostring(); } static public string getcpustring(){ if(build.cpu_abi.equalsignorecase("x86")){ return "intel"; } string strinfo = ""; try { byte[] bs = new byte[1024]; randomaccessfile reader = new randomaccessfile("/proc/cpuinfo", "r"); reader.read(bs); string ret = new string(bs); int index = ret.indexof(0); if(index != -1) { strinfo = ret.substring(0, index); } else { strinfo = ret; } } catch (ioexception ex){ ex.printstacktrace(); } return strinfo; } static public string getcputype(){ string strinfo = getcpustring(); string strtype = null; if (strinfo.contains("armv5")) { strtype = "armv5"; } else if (strinfo.contains("armv6")) { strtype = "armv6"; } else if (strinfo.contains("armv7")) { strtype = "armv7"; } else if (strinfo.contains("intel")){ strtype = "x86"; }else{ strtype = "unknown"; return strtype; } if (strinfo.contains("neon")) { strtype += "_neon"; }else if (strinfo.contains("vfpv3")) { strtype += "_vfpv3"; }else if (strinfo.contains(" vfp")) { strtype += "_vfp"; }else{ strtype += "_none"; } return strtype; } public static cpuinfo getcpuinfo() { string strinfo = null; try { byte[] bs = new byte[1024]; randomaccessfile reader = new randomaccessfile("/proc/cpuinfo", "r"); reader.read(bs); string ret = new string(bs); int index = ret.indexof(0); if(index != -1) { strinfo = ret.substring(0, index); } else { strinfo = ret; } } catch (ioexception ex) { strinfo = ""; ex.printstacktrace(); } cpuinfo info = parsecpuinfo(strinfo); info.mcpumaxfreq = getmaxcpufreq(); return info; } private final static string kcpuinfomaxfreqfilepath = "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq"; private static int getmaxcpufreq() { int result = 0; filereader fr = null; bufferedreader br = null; try { fr = new filereader(kcpuinfomaxfreqfilepath); br = new bufferedreader(fr); string text = br.readline(); if (text != null) { result = integer.parseint(text.trim()); } } catch (filenotfoundexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } finally { if (fr != null) try { fr.close(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } if (br != null) try { br.close(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } } return result; } public static class cpuinfo{ public cpuinfo(){ } public static final int cpu_type_unknown = 0x00000000; public static final int cpu_type_armv5te = 0x00000001; public static final int cpu_type_armv6 = 0x00000010; public static final int cpu_type_armv7 = 0x00000100; public static final int cpu_feature_unknows = 0x00000000; public static final int cpu_feature_vfp = 0x00000001; public static final int cpu_feature_vfpv3 = 0x00000010; public static final int cpu_feature_neon = 0x00000100; public int mcputype; public int mcpucount; public int mcpufeature; public double mbogomips; public long mcpumaxfreq; } private static cpuinfo parsecpuinfo(string cpuinfo) { if (cpuinfo == null || "".equals(cpuinfo)) { return null; } cpuinfo ci = new cpuinfo(); ci.mcputype = cpuinfo.cpu_type_unknown; ci.mcpufeature = cpuinfo.cpu_feature_unknows; ci.mcpucount = 1; ci.mbogomips = 0; if (cpuinfo.contains("armv5")) { ci.mcputype = cpuinfo.cpu_type_armv5te; } else if (cpuinfo.contains("armv6")) { ci.mcputype = cpuinfo.cpu_type_armv6; } else if (cpuinfo.contains("armv7")) { ci.mcputype = cpuinfo.cpu_type_armv7; } if (cpuinfo.contains("neon")) { ci.mcpufeature |= cpuinfo.cpu_feature_neon; } if (cpuinfo.contains("vfpv3")) { ci.mcpufeature |= cpuinfo.cpu_feature_vfpv3; } if (cpuinfo.contains(" vfp")) { ci.mcpufeature |= cpuinfo.cpu_feature_vfp; } string[] items = cpuinfo.split("\n"); for (string item : items) { if (item.contains("cpu variant")) { int index = item.indexof(": "); if (index >= 0) { string value = item.substring(index + 2); try { ci.mcpucount = integer.decode(value); ci.mcpucount = ci.mcpucount == 0 ?
