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

您想致电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AndroidManifest.xml中的以下权限：

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

为了做到这一点。

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式，并引发了隐私问题。不推荐。相反，如果要实现无摩擦登录系统，请查看Google+ Login API。

如果您只是想要一种轻量级的方式来保存用户重置手机（或购买新设备）时的字符串，那么Android Backup API也可用。

Answer 2

除了Trevor Johns的回答，您可以按如下方式使用：

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

当设备没有电话功能时，我使用以下代码获取IMEI或使用Secure.ANDROID_ID作为替代方案：

/**
 * 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对其进行更改（这显然不常见但不是不可能），则可以更改。

此处仅供参考，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对系统架构至关重要，则需要注意实际上一些非常低端的Android手机＆amp;已发现平板电脑重复使用相同的ANDROID_ID（9774d56d682e549c是我们日志中显示的值）

Answer 5

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号码：

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 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;
}

Answer 8

新更新：

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

<强> 更新

对于设备的唯一标识，您可以使用Secure.ANDROID_ID。

旧答案：

将IMEI用作唯一设备ID的缺点：

IMEI依赖于设备的Simcard插槽，因此不是可以为不使用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SIM卡插槽。

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。因此您将获得虚假价值）

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（智能手机和智能手机）的唯一标识符片）。
如果重新安装该应用程序，它仍然是唯一的

使用WLAN MAC地址作为设备ID的缺点：

从Marshmallow及以上给你一个虚假价值。
如果设备没有wifi硬件，那么你得到空的MAC地址，但一般来说，大多数Android设备都有wifi 硬件和市场上几乎没有设备没有wifi 硬件

Answer 9

与API 26一样，折旧了getDeviceId（），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;
 }

}
}

<强> 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></textview></linearlayout>

需要许可 清单文件中的READ_PHONE_STATE。

Answer 11

您可以使用此TelephonyManager TELEPHONY_SERVICE 功能获取 唯一设备ID ，需要权限：READ_PHONE_STATE

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

例如， IMEI for GSM 和 MEID或ESN for CDMA 手机。

/**
 * 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，

返回null 。

Answer 12

不建议使用方法getDeviceId()。为此getImei(int)

提供了一种新方法

Answer 13

使用以下代码为您提供IMEI号码：

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
System.out.println("IMEI::" + telephonyManager.getDeviceId());

Answer 14

适用于API等级11或以上：

case TelephonyManager.PHONE_TYPE_SIP: 
return "SIP";

TelephonyManager tm= (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
textDeviceID.setText(getDeviceID(tm));

Answer 15

Kotlin代码，用于获取具有所有Android版本的处理权限和可比性检查的DeviceId（IMEI）：

 val  telephonyManager = getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
        == PackageManager.PERMISSION_GRANTED) {
        // Permission is  granted
        val imei : String? = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)  telephonyManager.imei
        // older OS  versions
        else  telephonyManager.deviceId

        imei?.let {
            Log.i("Log", "DeviceId=$it" )
        }

    } else {  // Permission is not granted

    }

还将此权限添加到AndroidManifest.xml：

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

Answer 16

您在AndroidManifest.xml中需要以下权限：

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

要获取 IMEI （国际移动设备标识符），如果它高于API级别26，则我们将telephonyManager.getImei()设为null，为此，我们使用 ANDROID_ID 作为唯一标识符。

 public static String getIMEINumber(@NonNull final Context context)
            throws SecurityException, NullPointerException {
        TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        String imei;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            assert tm != null;
            imei = tm.getImei();
            //this change is for Android 10 as per security concern it will not provide the imei number.
            if (imei == null) {
                imei = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
            }
        } else {
            assert tm != null;
            if (tm.getDeviceId() != null && !tm.getDeviceId().equals("000000000000000")) {
                imei = tm.getDeviceId();
            } else {
                imei = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
            }
        }

        return imei;
    }

Answer 17

使用以下代码：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        String[] permissions = {Manifest.permission.READ_PHONE_STATE};
        if (ActivityCompat.checkSelfPermission(this,
                Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(permissions, READ_PHONE_STATE);
        }
    } else {
        try {
            TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
            String imei = telephonyManager.getDeviceId();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

并调用以下代码的onRequestPermissionsResult方法：

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case READ_PHONE_STATE:
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED)
                try {
                    TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
                    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
                        return;
                    }
                    String imei = telephonyManager.getDeviceId();

                } catch (Exception e) {
                    e.printStackTrace();
                }
    }
}

在您的AndroidManifest.xml中添加以下权限：

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

Answer 18

您无法从安卓 10+ 或 29+ 手机获取 imei 号码，这里是用于为设备创建 imei 号码的替代功能。

public  static String getDeviceID(){
    String devIDShort = "35" + //we make this look like a valid IMEI
            Build.BOARD.length()%10+ Build.BRAND.length()%10 +
            Build.CPU_ABI.length()%10 + Build.DEVICE.length()%10 +
            Build.DISPLAY.length()%10 + Build.HOST.length()%10 +
            Build.ID.length()%10 + Build.MANUFACTURER.length()%10 +
            Build.MODEL.length()%10 + Build.PRODUCT.length()%10 +
            Build.TAGS.length()%10 + Build.TYPE.length()%10 +
            Build.USER.length()%10 ; //13 digits

    return  devIDShort;
}

Answer 19

对于那些寻找Kotlin版本的人，您可以使用类似这样的东西；

private fun telephonyService() {
    val telephonyManager = getSystemService(TELEPHONY_SERVICE) as TelephonyManager
    val imei = if (android.os.Build.VERSION.SDK_INT >= 26) {
        Timber.i("Phone >= 26 IMEI")
        telephonyManager.imei
    } else {
        Timber.i("Phone IMEI < 26")
        telephonyManager.deviceId
    }

    Timber.i("Phone IMEI $imei")
}

注意：您必须使用checkSelfPermission或您使用的任何方法对上述telephonyService()进行权限检查。

还要将此权限添加到清单文件中；

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

Answer 20

尝试一下（需要始终获得第一个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();
        }

    if (responseStatus == ResponseStatus.SUCCESS.getValue()) {
        System.out.println("Method " + signature + " returned its result");
        metrics.get(signature).get(SUCCESS).increment();
    } else if (errorCodes.contains(responseStatus)) {
        System.out.println("Method " + signature + " returned error");
        metrics.get(signature).get(ERROR).increment();
    } else if (businessErrorCodes.contains(responseStatus)) {
        System.out.println("Method " + signature + " returned business error");
