我想通过 Android 4.4 发送 Beacon。 (银河枢纽)
这里有帮助：
enter link description here
在我的 android 应用中：
fun onClickTransmittingBeacon(view: View) {
val result = BeaconTransmitter.checkTransmissionSupported(this)
Log.d(TAG, "onClickTransmittingBeacon, result = $result")
val beacon = Beacon.Builder()
.setId1("2f234454-cf6d-4a0f-adf2-f4911ba9ffa6")
.setId2("1")
.setId3("2")
.setManufacturer(0x0118)
.setTxPower(-59)
.setDataFields(Arrays.asList(*arrayOf(0L)))
.build()
val beaconParser = BeaconParser().setBeaconLayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25")
val beaconTransmitter = BeaconTransmitter(applicationContext, beaconParser)
beaconTransmitter.startAdvertising(beacon)
}
在logcat中：
onClickTransmittingBeacon, result = 1
所以我的设备支持 BLE。不错
但为什么在 logcat 中出现运行时异常：
