android - java.lang.NoSuchMethodError: android.bluetooth.BluetoothAdapter.getBluetoothLeAdvertiser

问题描述

我想通过Android 4.4 传输 Beacon。（银河系）

此处帮助： 在此处输入链接描述

在我的安卓应用中：

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

因此，我的设备支持 BLE。好的。

但是为什么在 logcat 中我得到运行时异常：

解决方案

Android 4.4 太旧了，无法支持。你需要Andorid 5。
