如何在android中以编程方式获取设备的IMEI/ESN？

Question

为了唯一地识别每个设备,我想使用IMEI(或CDMA设备的ESN号码).如何以编程方式访问？

Answer 1

你想打电话android.telephony.TelephonyManager.getDeviceId().

这将返回唯一标识设备的字符串(GSM上的IMEI,CDMA的MEID).

您需要以下权限AndroidManifest.xml:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

为此.

话虽如此,小心这样做.用户不仅会想知道您的应用程序为何要访问其电话堆栈,而且如果用户获得新设备,则可能难以迁移数据.

更新:如下面的评论中所述,这不是一种对用户进行身份验证的安全方法,并引发了隐私问题.不推荐.相反,如果您要实施无摩擦登录系统,请查看Google+登录API.

在Android的备份API也可以,如果你只想要一个轻量级的方式来坚持字符串当用户重新设置自己的手机(或购买新设备)的包.

Answer 2

除了Trevor Johns的答案,你可以使用如下:

TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.getDeviceId();

您应该将以下权限添加到Manifest.xml文件中:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

在模拟器中,您可能会得到类似"00000 ......"的值.如果设备ID不可用,则getDeviceId()返回NULL.

Answer 3

我用下面的代码来获取IMEI或使用Secure.ANDROID_ID作为替代,当设备没有电话功能:

/**
 * Returns the unique identifier for the device
 *
 * @return unique identifier for the device
 */
public String getDeviceIMEI() {
    String deviceUniqueIdentifier = null;
    TelephonyManager tm = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
    if (null != tm) {
        deviceUniqueIdentifier = tm.getDeviceId();
    }
    if (null == deviceUniqueIdentifier || 0 == deviceUniqueIdentifier.length()) {
        deviceUniqueIdentifier = Settings.Secure.getString(this.getContentResolver(), Settings.Secure.ANDROID_ID);
    }
    return deviceUniqueIdentifier;
}

Answer 4

或者您可以使用Android.Provider.Settings.System中的ANDROID_ID设置(如此处所述strazerre.com).

这样做的好处是它不需要特殊权限,但如果另一个应用程序具有写访问权限并且更改它(这显然不常见但不是不可能),则可以更改.

这里仅供参考,是博客中的代码:

import android.provider.Settings;
import android.provider.Settings.System;   

String androidID = System.getString(this.getContentResolver(),Secure.ANDROID_ID);

实施说明:如果ID是系统架构,你需要知道,在实践中一些非常低端的Android手机和平板已发现重复使用相同的ANDROID_ID关键(9774d56d682e549c是显示我们的原木达价值)

来自:http://mytechead.wordpress.com/2011/08/28/how-to-get-imei-number-of-android-device/:

以下代码有助于获取Android设备的IMEI号:

TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String device_id = tm.getDeviceId();

Android Manifest中所需的权限:

android.permission.READ_PHONE_STATE

注意:如果平板电脑或设备无法充当移动电话,则IMEI将为空.

Answer 6

获取IMEI(国际移动设备标识符)

public String getIMEI(Activity activity) {
    TelephonyManager telephonyManager = (TelephonyManager) activity
            .getSystemService(Context.TELEPHONY_SERVICE);
    return telephonyManager.getDeviceId();
}

获取设备唯一ID

public String getDeviceUniqueID(Activity activity){
    String device_unique_id = Secure.getString(activity.getContentResolver(),
            Secure.ANDROID_ID);
    return device_unique_id;
}

对于Android 6.0+,游戏已经改变,所以我建议你使用它;

最好的方法是在运行时运行,否则会出现权限错误.

Answer 8

新更新:

对于Android版本6及以上版本,WLAN MAC地址已被弃用,请按照Trevor Johns的说法进行操作

更新:

要唯一标识设备,您可以使用Secure.ANDROID_ID.

旧答案:

使用IMEI作为唯一设备ID的缺点:

• IMEI依赖于设备的SIM卡插槽,因此无法为不使用Simcard的设备获取IMEI.在双SIM卡设备中,我们为同一设备获得2个不同的IMEI,因为它有2个用于SIM卡的插槽.

您可以使用WLAN MAC地址字符串(不推荐用于Marshmallow和Marshmallow +,因为WLAN MAC地址已被Marshmallow转发使用.因此您将获得虚假值)

我们也可以使用WLAN MAC地址获取Android手机的唯一ID.MAC地址对所有设备都是唯一的,适用于各种设备.

使用WLAN MAC地址作为设备ID的优点:

• 它是所有类型设备(智能手机和平板电脑)的唯一标识符.

• 如果重新安装应用程序,它仍然是唯一的

使用WLAN MAC地址作为设备ID的缺点:

• 给你一个来自棉花糖及以上的虚假价值.

• 如果设备没有wifi硬件,那么你会得到空MAC地址,但通常可以看到大多数Android设备都有wifi硬件,市场上几乎没有设备没有wifi硬件.

Answer 9

与API 26中一样,getDeviceId()已被折旧,因此您可以使用以下代码来满足API 26及更早版本的需求

TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String imei="";
if (android.os.Build.VERSION.SDK_INT >= 26) {
  imei=telephonyManager.getImei();
}
else
{
  imei=telephonyManager.getDeviceId();
}

不要忘记添加"READ_PHONE_STATE"的权限请求以使用上面的代码.

Answer 10

TelephonyManager的getDeviceId()方法返回唯一的设备ID,例如GSM的IMEI和CDMA手机的MEID或ESN.如果设备ID不可用,则返回null.

Java代码

package com.AndroidTelephonyManager;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.widget.TextView;

public class AndroidTelephonyManager extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TextView textDeviceID = (TextView)findViewById(R.id.deviceid);

    //retrieve a reference to an instance of TelephonyManager
    TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

    textDeviceID.setText(getDeviceID(telephonyManager));

}

String getDeviceID(TelephonyManager phonyManager){

 String id = phonyManager.getDeviceId();
 if (id == null){
  id = "not available";
 }

 int phoneType = phonyManager.getPhoneType();
 switch(phoneType){
 case TelephonyManager.PHONE_TYPE_NONE:
  return "NONE: " + id;

 case TelephonyManager.PHONE_TYPE_GSM:
  return "GSM: IMEI=" + id;

 case TelephonyManager.PHONE_TYPE_CDMA:
  return "CDMA: MEID/ESN=" + id;

 /*
  *  for API Level 11 or above
  *  case TelephonyManager.PHONE_TYPE_SIP:
  *   return "SIP";
  */

 default:
  return "UNKNOWN: ID=" + id;
 }

}
}

XML

<linearlayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android">
<textview android:layout_height="wrap_content" android:layout_width="fill_parent" android:text="@string/hello">
<textview android:id="@+id/deviceid" android:layout_height="wrap_content" android:layout_width="fill_parent">
</textview></textview></linearlayout> 

清单文件中的权限 READ_PHONE_STATE.

Answer 11

您可以使用此 TelephonyManager TELEPHONY_SERVICE函数来获取唯一的设备 ID，需要权限：READ_PHONE_STATE

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

例如，GSM的IMEI和CDMA手机的MEID 或 ESN。

/**
 * Gets the device unique id called IMEI. Sometimes, this returns 00000000000000000 for the
 * rooted devices.
 **/
public static String getDeviceImei(Context ctx) {
    TelephonyManager telephonyManager = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);
    return telephonyManager.getDeviceId();
}

如果设备 ID 不可用，则返回 null。

Answer 12

试试这个（始终需要获取第一个 IMEI）

TelephonyManager mTelephony = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        if (ActivityCompat.checkSelfPermission(LoginActivity.this,Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED) {

         return;
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                if (mTelephony.getPhoneCount() == 2) {
                    IME = mTelephony.getImei(0);
                }else{
                    IME = mTelephony.getImei();
                }
            }else{
                if (mTelephony.getPhoneCount() == 2) {
                    IME = mTelephony.getDeviceId(0);
                } else {
                    IME = mTelephony.getDeviceId();
                }
            }
        } else {
            IME = mTelephony.getDeviceId();
        }
