android系统信息

1：通过Build类和System类来获取系统的信息，具体代码如下所示：

 private String getDeviceInfo() {
        StringBuffer sb = new StringBuffer();
        sb.append("主板：" + Build.BOARD);
        sb.append("\n系统启动程序版本号：" + Build.BOOTLOADER);
        sb.append("\n系统定制商：" + Build.BRAND);
        sb.append("\ncpu指令集：" + Build.CPU_ABI);
        sb.append("\ncpu指令集2" + Build.CPU_ABI2);
        sb.append("\n设置参数：" + Build.DEVICE);
        sb.append("\n显示屏参数：" + Build.DISPLAY);
        sb.append("\n无线电固件版本：" + Build.getRadioVersion());
        sb.append("\n硬件识别码：" + Build.FINGERPRINT);
        sb.append("\n硬件名称：" + Build.HARDWARE);
        sb.append("\nHOST:" + Build.HOST);
        sb.append("\n修订版本列表：" + Build.ID);
        sb.append("\n硬件制造商：" + Build.MANUFACTURER);
        sb.append("\n版本：" + Build.MODEL);
        sb.append("\n硬件序列号：" + Build.SERIAL);
        sb.append("\n手机制造商：" + Build.PRODUCT);
        sb.append("\n描述Build的标签：" + Build.TAGS);
        sb.append("\nTIME:" + Build.TIME);
        sb.append("\nbuilder类型：" + Build.TYPE);
        sb.append("\nUSER:" + Build.USER);
        sb.append("\n路径分隔符:" + System.getProperty("path.separator"));
        sb.append("\n行分隔符:" + System.getProperty("line.separator"));
        sb.append("\n文件分隔符:" + System.getProperty("file.separator"));
        sb.append("\njava版本:" + System.getProperty("java.version"));
        return sb.toString();
    }
输出结果为：

                                          路径分隔符::
                                          行分隔符:

                                          java版本:0

2：PackageManager

常用的方法如下所示：

示例代码如下：

PackageManager packageManager=getPackageManager();   Listlist=packageManager.getInstalledApplications(PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);
        for (int i = 0; i < list.size(); i++) {
            Log.d("CeShi", list.get(i).toString()+"\n");//输出手机上安装的app的包信息
        }

3：ActivityManager

示例代码如下：

ActivityManager activityManager= (ActivityManager) getSystemService(ACTIVITY_SERVICE);    Listlist=activityManager.getRunningAppProcesses();
                for (int i = 0; i < list.size(); i++) {
                    Debug.MemoryInfo[] memoryInfos=activityManager.getProcessMemoryInfo(new int[]{list.get(i).pid});
                    Log.d("CeShi", list.get(i).processName + "," +memoryInfos[i].getTotalPss());//只输出了当前app进程，输出结果为：com.example.liang.arlvyou,12877
                }
