怎么用代码判断Android手机的Rom是MIUI及获取MIUI版本

参考Android源码:

https://code.google.com/p/cyanogen-updater/source/browse/trunk/src/cmupdaterapp/utils/SysUtils.java#19

在Android shell模式下输入 getprop 就能获取系统属性值

如果Rom是miUI那么就会有以下字段.

 [ro.miui.ui.version.code]: [3]
[ro.miui.ui.version.name]: [V5] 

那么只要用一下代码获取就能知道是不是UI了. 

getSystemProperty("ro.miui.ui.version.name")

public static String getSystemProperty(String propName){ String line; BufferedReader input = null; try { Process p = Runtime.getRuntime().exec("getprop " + propName); input = new BufferedReader(new InputStreamReader(p.getInputStream()), 1024); line = input.readLine(); input.close(); } catch (IOException ex) { Log.e(TAG, "Unable to read sysprop " + propName, ex); return null; } finally { if(input != null) { try { input.close(); } catch (IOException e) { Log.e(TAG, "Exception while closing InputStream", e); } } } return line; }
