查看Android设备的CPU架构信息

android系统其实是linux,那么可以在程序中去调用cat /proc/meminfo和cat 
/proc/cpuino去查看内存和CPU等情况的,下面是程序:

1. public class CpuSpeed extends Activity {
2. /** Called when the activity is first created. */
3. private TextView cpuInfo;
4. private TextView memoryInfo;
5. public void onCreate(Bundle savedInstanceState) {
6. super.onCreate(savedInstanceState);
7. setContentView(R.layout.main);
8. cpuInfo=(TextView)findViewById(R.id.cpuinfo);
9. cpuInfo.setText(getCPUinfo());
10. memoryInfo = (TextView)findViewById(R.id.memoryinfo);
11. memoryInfo.setText(getMemoryInfo());
12. }
13. private String getMemoryInfo(){
14. ProcessBuilder cmd;
15. String result = new String();
16. try{
17. String[] args = {"/system/bin/cat", "/proc/meminfo"};
18. cmd = new ProcessBuilder(args);
19. Process process = cmd.start();
20. InputStream in = process.getInputStream();
21. byte[] re=new byte[1024];
22. while (in.read(re)!=-1)
23. {
24. System.out.println(new String(re));
25. result = result + new String(re);
26. }
27. in.close();
28. }
29. catch(IOException ex){
30. ex.printStackTrace();
31. }
32. return result;
33. }
34. private String getCPUinfo()
35. {
36. ProcessBuilder cmd;
37. String result="";
38. try{
39. String[] args = {"/system/bin/cat", "/proc/cpuinfo"};
40. cmd = new ProcessBuilder(args);
41. Process process = cmd.start();
42. InputStream in = process.getInputStream();
43. byte[] re = new byte[1024];
44. while(in.read(re) != -1){
45. System.out.println(new String(re));
46. result = result + new String(re);
47. }
48. in.close();
49. } catch(IOException ex){
50. ex.printStackTrace();
51. }
52. return result;
53. }

}

其实核心无非就是ProcessBuilder的运用,去启动命令行去读操作系统, 
String[] args = {"/system/bin/cat", "/proc/cpuinfo"};

1. cmd = new ProcessBuilder(args);
2. Process process = cmd.start();
3. InputStream in = process.getInputStream();

然后再IO输入流读入就可以了
