Android_获取手机设备信息device_id

本文主要是介绍Android_获取手机设备信息device_id，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

执行：getDeviceInfo(Context context) 方法，返回结果就是设备信息

 /*** 获取设备的信息* @param context* @param permission* @return*/public static boolean checkPermission(Context context, String permission) {boolean result = false;if (Build.VERSION.SDK_INT >= 23) {try {Class<?> clazz = Class.forName("android.content.Context");Method method = clazz.getMethod("checkSelfPermission", String.class);int rest = (Integer) method.invoke(context, permission);if (rest == PackageManager.PERMISSION_GRANTED) {result = true;} else {result = false;}} catch (Exception e) {result = false;}} else {PackageManager pm = context.getPackageManager();if (pm.checkPermission(permission, context.getPackageName()) == PackageManager.PERMISSION_GRANTED) {result = true;}}return result;}

public static String getDeviceInfo(Context context) {try {org.json.JSONObject json = new org.json.JSONObject();android.telephony.TelephonyManager tm = (android.telephony.TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);String device_id = null;if (checkPermission(context, Manifest.permission.READ_PHONE_STATE)) {device_id = tm.getDeviceId();}String mac = null;FileReader fstream = null;try {fstream = new FileReader("/sys/class/net/wlan0/address");} catch (FileNotFoundException e) {fstream = new FileReader("/sys/class/net/eth0/address");}BufferedReader in = null;if (fstream != null) {try {in = new BufferedReader(fstream, 1024);mac = in.readLine();} catch (IOException e) {} finally {if (fstream != null) {try {fstream.close();} catch (IOException e) {e.printStackTrace();}}if (in != null) {try {in.close();} catch (IOException e) {e.printStackTrace();}}}}json.put("mac", mac);if (TextUtils.isEmpty(device_id)) {device_id = mac;}if (TextUtils.isEmpty(device_id)) {device_id = android.provider.Settings.Secure.getString(context.getContentResolver(),android.provider.Settings.Secure.ANDROID_ID);}json.put("device_id", device_id);return json.toString();} catch (Exception e) {e.printStackTrace();}return null;}
