android获取cpu信息 安卓获取cpu型号

1、最简单的是使用Build的信息。

import android.os.Build;

String cpu = Build.CPU_ABI;cpu.startWith("arm");

2、使用系统文件/proc/cpuinfo

1. try {  
2. new FileInputStream("/proc/cpuinfo");  
3. new InputStreamReader(is);  
4. new BufferedReader(ir);  
5. try {  
6. "Processor";  
7. "Features";  
8. "model name";  
9. "cpu family";  
10. while (true) {  
11.                 String line = br.readLine();  
12. null;  
13. if (line == null) {  
14. break;  
15.                 }  
16. ":");  
17. if (pair.length != 2)  
18. continue;  
19. 0].trim();  
20. 1].trim();  
21. if (key.compareTo(nameProcessor) == 0) {  
22. "";  
23. for (int i = val.indexOf("ARMv") + 4; i < val.length(); i++) {  
24. "";  
25. if (temp.matches("\\d")) {  
26.                             n += temp;  
27. else {  
28. break;  
29.                         }  
30.                     }  
31. 0] = "ARM";  
32. 1] = Integer.parseInt(n);  
33. continue;  
34.                 }  
35.   
36. if (key.compareToIgnoreCase(nameFeatures) == 0) {  
37. if (val.contains("neon")) {  
38. 2] = "neon";  
39.                     }  
40. continue;  
41.                 }  
42.   
43. if (key.compareToIgnoreCase(nameModel) == 0) {  
44. if (val.contains("Intel")) {  
45. 0] = "INTEL";  
46. 2] = "atom";  
47.                     }  
48. continue;  
49.                 }  
50.   
51. if (key.compareToIgnoreCase(nameCpuFamily) == 0) {  
52. 1] = Integer.parseInt(val);  
53. continue;  
54.                 }  
55.             }  
56. finally {  
57.             br.close();  
58.             ir.close();  
59.             is.close();  
60.         }  
61. catch (Exception e) {  
62.         e.printStackTrace();  
63.     }
