本文介绍了一个用于获取Android设备IMEI号的Java工具类。通过使用TelephonyManager和Settings.Secure类，该方法能够确保在拥有相应权限的情况下获取设备的唯一标识符。在权限不足时，会返回空字符串并提示请求权限。

这是刚刚实习用到设备识别码的时候带我的大哥给的，留下来以备不时之需。

import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.telephony.TelephonyManager;
import android.util.Log;

import java.util.UUID;

    public static String getUUID(Context context) {

        final TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

        final String tmDevice, tmSerial, androidId;

        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,

            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return "";
        }
        tmDevice = "" + tm.getDeviceId();

        androidId = "" + android.provider.Settings.Secure.getString(context.getContentResolver(),android.provider.Settings.Secure.ANDROID_ID);

        UUID deviceUuid = new UUID(androidId.hashCode(), ((long)tmDevice.hashCode() << 32));

        String uniqueId = deviceUuid.toString();

        Log.e("debug","uuid="+uniqueId);

        return uniqueId;

    }
}
