• 獲得手機root權限

adb shell

su

cd system

cat build.prop

可找到第三方rom系統(tǒng)的版本，比如ro.build.version.emui=EmotionUI_2.0，這里我們需要的是第三方rom系統(tǒng)的key，如例子中的ro.build.version.emui.

• 如何在代碼中獲得版本呢？即要獲得EmotionUI_2.0.參考參考Android源碼:

   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("dingyi", "Unable to read sysprop " + propName, ex);
            return null;
        } finally {
            if (input != null) {
                try {
                    input.close();
                } catch (IOException e) {
                    Log.e("dingyi", "Exception while closing InputStream", e);
                }
            }
        }
        return line;
    }

調(diào)用getSystemProperty("ro.build.version.emui")即可獲得第三方rom系統(tǒng)版本號
