************************************我找到的最好方法：********** ****************************** ******************************成功完成************************ *************** *****************************只需复制以下代码********************** ********************

清单：

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

JAVA: 在 onCreate 中：

String deviceIMEI;

CheckPermissionAndStartIntent();

在根目录中：

private void CheckPermissionAndStartIntent() {
    if (ContextCompat.checkSelfPermission(SplashActivity.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED
            || ContextCompat.checkSelfPermission(SplashActivity.this, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_DENIED) {
        ActivityCompat.requestPermissions(SplashActivity.this, new String[]{Manifest.permission.READ_PHONE_STATE}, 1);
        //SEY SOMTHING LIKE YOU CANT ACCESS WITHOUT PERMISSION
    } else {
        doSomthing();
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
    switch (requestCode) {
        case 1: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                doSomthing();
            } else if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_DENIED) {
                //SEY SOMTHING LIKE YOU CANT ACCESS WITHOUT PERMISSION
                //you can show something to user and open setting -> apps -> youApp -> permission
                // or unComment below code to show permissionRequest Again
                //ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_PHONE_STATE}, 1);
            }
        }
    }
}


doSomthing() {
    deviceIMEI = getDeviceIMEI(MainActivity.this);
    //andGoToYourNextStep
}

@SuppressLint("HardwareIds")
public static String getDeviceIMEI(Activity activity) {

    String deviceUniqueIdentifier = null;
    TelephonyManager tm = (TelephonyManager) activity.getSystemService(Context.TELEPHONY_SERVICE);
    if (null != tm) {
        if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED)
            ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.READ_PHONE_STATE}, 1);
        else
            deviceUniqueIdentifier = tm.getDeviceId();
        if (null == deviceUniqueIdentifier || 0 == deviceUniqueIdentifier.length())
            deviceUniqueIdentifier = "0";
    }
    return deviceUniqueIdentifier;
}

我看到了那个主题，但我找不到我的结果

标签： java android imei

【解决方案1】：

请使用这个

清单文件

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

在 Java 文件中

 public static String getUniqueIMEIId(Context context) {
    try {
        TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return "";
        }
        String imei = telephonyManager.getDeviceId();
        Log.e("imei", "=" + imei);
        if (imei != null && !imei.isEmpty()) {
            return imei;
        } else {
            return android.os.Build.SERIAL;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return "not_found";
}

【讨论】：

thanQ 但那是返回 null --> ( " " )
您是否正在检查 Android 设备？
是的，我的设备是真实的，不是虚拟设备：'(
好的。你在你的应用程序中允许运行时权限吗？
使用：字符串imei = telephonyManager.getImei();字符串序列 = android.os.Build.getSerial();对于新版本的 android sdks（例如我目前使用的 API 27）

【解决方案2】：

试试这个

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling

        return;
    }
    String imei = telephonyManager.getDeviceId();

在 Manifest.xml 中添加权限

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

【解决方案3】：

public  String getIMEI(final Context context) {
    final TelephonyManager ts =
    (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    return ts.getDeviceId()) ;
}

确保您拥有 Manifest.permission.READ_PHONE_STATE 权限
