题
以识别每个的设备唯一我想利用本身的信息(或ESN数址的设备)。如何进入这一程?
解决方案
您要拨打 android.telephony.TelephonyManager.getDeviceId()
。
这将返回的任何字符串唯一地标识设备(IMEI上GSM,MEID为CDMA)。
您需要在您的AndroidManifest.xml
以下权限:
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
为了做到这一点。
话虽这么说,要小心这样做。不仅将用户想知道为什么你的应用程序访问他们的电话协议栈,它可能很难如果用户得到一个新的设备上迁移数据。
更新:由于在下面的评论中提到,这不是来验证用户的可靠方法,并提出了隐私问题。不推荐。相反,看看 Google+帐户登录API 如果你想实现一个无摩擦登录系统。
在的Android备份API 也可以,如果你只是想轻量级的方式坚持串束当用户复位他们的电话(或购买新设备),用于
其他提示
在除了特雷弗约翰的答案,则可以使用此,如下所示:
TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.getDeviceId();
和你应该添加下列权限到您的Manifest.xml文件:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
在模拟器,你可能会得到一个像“00000 ......”值。如果设备ID是不可用getDeviceId()返回NULL。
我使用下面的代码来获取IMEI或使用Secure.ANDROID_ID作为替代,当设备不具有电话功能:
/**
* 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;
}
或者可以使用ANDROID_ID设置从Android.Provider.Settings.System(如这里所描述 strazerre。 COM )。
这具有的优点是它不需要特殊的权限,但可以改变,如果另一个应用程序具有写访问,并改变它(这是明显异常,但不是不可能)。
只是为了参考这里是从博客的代码:
import android.provider.Settings;
import android.provider.Settings.System;
String androidID = System.getString(this.getContentResolver(),Secure.ANDROID_ID);
实现注意:如果ID是系统架构的关键,你需要知道,在实践中一些非常低端的Android手机和平板已经发现重用相同ANDROID_ID (9774d56d682e549c是示出在我们的日志起来的值)
自: HTTP ://mytechead.wordpress.com/2011/08/28/how-to-get-imei-number-of-android-device/ :
下面的代码有助于获得机器人的装置的IMEI号:
TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String device_id = tm.getDeviceId();
权限在Android清单需要:
android.permission.READ_PHONE_STATE
注意:在片剂中或设备的情况下,其不能作为移动电话 IMEI将为空。
要得到的 IMEI 强>(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();
}
要得到的设备唯一id 强>
public String getDeviceUniqueID(Activity activity){
String device_unique_id = Secure.getString(activity.getContentResolver(),
Secure.ANDROID_ID);
return device_unique_id;
}
有关的Android 6.0+游戏已经改变,所以我建议你使用此;
去的最好方法是运行否则你得到许可的错误中。

新更新:
对于安卓版本6及以上,WLAN MAC地址已经过时,按照特雷弗*约翰回答
更新:
对于独特的识别设备,可以使用 安全。ANDROID_ID.
旧的回答:
缺点使用身的信息作为唯一的设备:
- 身的信息依赖于卡贴槽设备,所以它不是 能够获得维的设备,不使用卡贴.在双卡的设备,我们得到2种不同的IMEIs于同样的设备,因为它有2槽卡贴.
你可以使用的WLAN MAC地址串(不建议对棉花糖和棉花糖+为WLAN MAC地址已经不在棉花糖前进。所以你会得到一个虚假的价值)
我们可以得到的唯一ID机使用WLAN MAC地址。MAC地址为唯一的为所有设备和它适用于所有类型的设备。
优点使用无线局域网MAC地址作为设备ID:
这是唯一的标识符为所有类型的设备(智能手机和 片)。
它仍然是独特的,如果应用程序被重装了
缺点使用无线局域网MAC地址作为设备ID:
给你一个假的价值从棉花糖和以上。
如果设备没有无线网络连接硬件然后你获得空MAC地址, 但一般可以看出,大多数的设备有无线网络 硬件和几乎没有几个设备在市场上有没有无线网络 硬件。

如在API 26 getDeviceId()折旧所以可以用下面的代码,以满足API 26和更早版本
TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String imei="";
if (android.os.Build.VERSION.SDK_INT >= 26) {
imei=telephonyManager.getImei();
}
else
{
imei=telephonyManager.getDeviceId();
}
不要忘记为“READ_PHONE_STATE”添加许可请求到上面的代码使用。
的方法getDeviceId(TelephonyManager的)返回唯一的设备ID,例如,IMEI对于GSM和MEID或ESN为CDMA电话。返回NULL如果设备ID是不可用的。

已弃用。
一个用于此getImei(int)
的新方法
下面使用代码给你IMEI号:
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
System.out.println("IMEI::" + telephonyManager.getDeviceId());
试试这个(需要总是得到第一IMEI)
TelephonyManager mTelephony = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (ActivityCompat.checkSelfPermission(LoginActivity.this,Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED) {
return;

有关API级别11或更高:
case TelephonyManager.PHONE_TYPE_SIP:
return "SIP";
TelephonyManager tm= (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
textDeviceID.setText(getDeviceID(tm));
科特林代码用于与处理权限&可比性检查对于所有的Android版本获得的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
}
而且此权限添加的AndroidManifest.xml:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/> <!-- IMEI-->
对于那些寻找科特林的版本,可以使用这样的事情;
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:你必须包裹 telephonyService()
上述权限,检查使用 checkSelfPermission 或什么方法使用。
也添加这一限清单中的文件;
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
