android wear nfc support

I. Preface descriptionAndroid Wear most of the display form is the form of cards, and the simplest way to support Android Wear is to use the notification **notification**. To achieve the simplest, non-highly customizable notifications, you only need to do some processing on the phone side, do not need to develop the wa

notifications (contextual notification) is generated locally on the wearable device and appears only at the relevant contextual point in time, such as when you run a card that appears to exercise your body. You can do more on this type of card than with notifications from a handheld device.* Full Screen application1, 2D picker (two-dimensional selector) is designed to allow users to choose from a range of options, such as selecting artists and genres, and so on. Whenever there is an association

Support NFC from Android2.3. But NFC apps can only be tested and developed on Android phones (or tablets), and Android phones must have NFC chips. And if you test NFC transfer files, yo

devices only support one NFC Adapter. You can use the getDefaultAapater method to obtain the system-supported Adapter. NfcAdapter class:The NFC adapter of this device can define the Intent to request the system to send the tags notification to your Activity and provide To register the front-end tag reminder release and front-end NDEF push. NdefMessage class:NDEF

This article introduces some advanced NFC topics, such as a variety of NFC tag technologies, NFC tag compilation, and foreground scheduling. Foreground scheduling allows applications on the foreground to prioritize Intent event scheduling, even if there are other applications that filter the same Intent event. NFC tag

format for the specification of the record type you want to create? Android also supports other tags that do not contain the NDEF data type, can you work with classes in the Android.nfc.tech package? To work with other types of labels, it involves writing your own protocol stack to communicate with that label, so we recommend that you use the ndef as much as possible, To reduce development difficulty and maximize

Android NFC Development Let's talk about NFC Development Summary, read NFC development materials for a few days, and collect a lot of information about this, demos, and other people's summaries. The following is an excerpt from the summary. If so, the code is provided. I also have a demo. I need to send an email to me

, why not open, in fact, Google is now making up a mistake, that is, because Android is too open to cause Android fragmentation, Google has no control over Android, domestic manufacturers that is even more. Thus, on Android for wearable devices, Google estimates that it would like to unify the interface to enhance the

wearable devices. In this format, cross-device display is possible.This standard is the Android notification. When a wearable device is connected to a handheld device, notifications from the handheld device are delivered to the wearable device. The wearable device then displays the notification in a manner that is appropriate for its own operation. Of course, in order to have a better display on the wearable device, developers need to make a few chan

Mobile Payment: Smart IC card for NFC communication with Android mobile phones; androidnfc This article from http://blog.csdn.net/hellogv/, reference must indicate the source! Currently, the common smart IC Card runs the JavaCard virtual machine, and the smart IC card can run the card application (Applet) compiled by the simplified Java language ). The Applet of the Smart IC card cannot be started by itself

in the near moment. In Android NFC applications, Android phones are usually the initiators of communication, that is, NFC readers. Android phones can also be used as NFC recipients and suppor
