Editing Functionality of Host Card Emulation in Android

阅读更多关于 Editing Functionality of Host Card Emulation in Android

I'm currently in the process of developing a project for my University course wherein I will be hopefully editing the functionality of the HCE Feature of Android to allow me to set my own UID when emulating a card. Now, i've downloaded the AOSP source, and built a custom image with no edited code and installed that to my Nexus 7 (This includes downloading and including the Vendor specific hardware drivers), and i'm stuck on the next part. I physically cannot find the device code that governs the NFC features of Android, and i'm unsure how to go about a) Looking for it, and b) How I should be

Android: How to programmatically access the device serial number shown in the AVD manager (API Version 8)

阅读更多关于 Android: How to programmatically access the device serial number shown in the AVD manager (API Version 8)

问题 How do I programmatically access the value shown in the image below ? 回答1: This is the hardware serial number. To access it on Android Q (>= SDK 29) android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE is required. Only system apps can require this permission. If the calling package is the device or profile owner then the READ_PHONE_STATE permission suffices. Android 8 and later (>= SDK 26) use android.os.Build.getSerial() which requires the dangerous permission READ_PHONE_STATE. Using

How to get hard disk serial number using Python

问题 How can I get the serial number of a hard disk drive using Python on Linux ? I would like to use a Python module to do that instead of running an external program such as hdparm. Perhaps using the fcntl module? 回答1: Linux As you suggested, fcntl is the way to do this on Linux. The C code you want to translate looks like this: static struct hd_driveid hd; int fd; if ((fd = open("/dev/hda", O_RDONLY | O_NONBLOCK)) < 0) { printf("ERROR opening /dev/hda\n"); exit(1); } if (!ioctl(fd, HDIO_GET

Serials on NFC Tags - truly unique? cloneable?

阅读更多关于 Serials on NFC Tags - truly unique? cloneable?

So are NFC tags really UNIQUE from each other, at least in their SERIAL NUMBER ? And can we rely on the fact that no 2 NFC tags can have the same serial number? I'm highly skeptical about this as there are (and will be more) NFC tags out there and I don't think anyone is controlling the serials... The reason I'm asking is that I'm developing a key based system using NFC tags. I don't need to write to the tags, I basically just need their serial numbers. But I need them to be truly unique . Also, I would like to know if the serial numbers can be cloned (I know the content of tags can always be

Android Unique Serial Number

阅读更多关于 Android Unique Serial Number

问题 I am developing an android application that targets Android 4.0 (API 14) and above. I am looking for a serial number that is unique per device and that persists for ever (dies with the device, does not change after factory resets). I have found lots of results on the web concerning unique identifiers for android devices, but very little on the android.os.Build.SERIAL number. So far, I eliminated the use of the ANDROID_ID because it might change after factory resets. I also eliminated the use

How to find serial number of Android device?

问题 I need to use a unique ID for an Android app and I thought the serial number for the device would be a good candidate. How do I retrieve the serial number of an Android device in my app ? 回答1: TelephonyManager tManager = (TelephonyManager)myActivity.getSystemService(Context.TELEPHONY_SERVICE); String uid = tManager.getDeviceId(); getSystemService is a method from the Activity class. getDeviceID() will return the MDN or MEID of the device depending on which radio the phone uses (GSM or CDMA).
