问题描述
我在创建项目时添加了它.从那时起,AndroidX Artifact(checkBox)尚未进行mqt通信.有什么问题吗?
Androidx用于使用BiometricPrompt.
下面是我的mqtt代码.↓
private lateinit var mqttAndroidClient: MqttAndroidClient
val CLINET_ID: String = MqttClient.generateClientId()
fun connect(applicationContext : Context) {
val context: Context = applicationContext
mqttAndroidClient = MqttAndroidClient ( context.applicationContext,"tcp://13.124.231.98:1883",
CLINET_ID )
try {
val token = mqttAndroidClient.connect()
token.actionCallback = object : IMqttActionListener {
override fun onSuccess(asyncActionToken: IMqttToken) {
Log.i("Connection", "success ")
//connectionStatus = true
// Give your callback on connection established here
// publish("test", "open")
}
override fun onFailure(asyncActionToken: IMqttToken, exception: Throwable) {
//connectionStatus = false
Log.i("Connection", "failure")
// Give your callback on connection failure here
exception.printStackTrace()
}
}
} catch (e: MqttException) {
// Give your callback on connection failure here
e.printStackTrace()
}
}
上面的代码中的错误-> val令牌= mqttAndroidClient.connect()

这是版本问题吗?
我尝试了BiometricPrompt.可以使用androidx以外的版本来解决此问题,但是生成Fragment并无法解决它的代码发生了错误.
最后,我认为在Androidx上运行mqtt会很好,所以我尝试了几次但失败了.
如果您与我有过类似的经历并且已经解决了问题,请帮忙.
您应在androidx
androidx.legacy:legacy-support-v4:1.0.0
androidx.localbroadcastmanager:localbroadcastmanager:1.0.0

Androidx is used to use BiometricPrompt.
Below is my mqtt code.↓
private lateinit var mqttAndroidClient: MqttAndroidClient
val CLINET_ID: String = MqttClient.generateClientId()
fun connect(applicationContext : Context) {
val context: Context = applicationContext
mqttAndroidClient = MqttAndroidClient ( context.applicationContext,"tcp://13.124.231.98:1883",
CLINET_ID )
try {
val token = mqttAndroidClient.connect()
token.actionCallback = object : IMqttActionListener {
override fun onSuccess(asyncActionToken: IMqttToken) {
Log.i("Connection", "success ")
//connectionStatus = true
// Give your callback on connection established here
// publish("test", "open")
}
override fun onFailure(asyncActionToken: IMqttToken, exception: Throwable) {
//connectionStatus = false
Log.i("Connection", "failure")
// Give your callback on connection failure here
exception.printStackTrace()
}
}
} catch (e: MqttException) {
// Give your callback on connection failure here
e.printStackTrace()
}
}
Errors in the code above -> val token = mqttAndroidClient.connect()

Is it a version problem?
I tried BiometricPrompt. in the version other than androidx to solve this problem, but an error occurred in the code that generated the Fragment and failed to resolve it.
Finally, I thought it would be good to run mqtt on Androidx, so I tried several times but failed.
If you've had a similar experience with me and you've solved it, help.
You should add the following dependencies to with androidx
androidx.legacy:legacy-support-v4:1.0.0
androidx.localbroadcastmanager:localbroadcastmanager:1.0.0
