After changing the version to Androidx, it does not become mqtt connect

Question

After changing version to Androidx and can not connect to mqtt server. It worked well in other versions than Androidx. Is this a version problem?

My source code and build information is on the link-> I added it when I made the project. AndroidX Artifact has not been mqt communication since then. What is the problem?

I solved the problem and added it to the build. an indication 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0' — 타터터, Nov 29 '19 at 10:33

Try setting android.enableJetifier=true in gradle.properties file. If that doesn't work, try adding implementation 'androidx.legacy:legacy-support-v4:1.0.0' to build.grade.

This problem has been solved before in the next links, I highly recommend checking them out, specially 420:

I had the same problem. I solved it. my solution:

Add this dependency to the build.gradle(:app)

implementation 'androidx.legacy:legacy-support-v4:1.0.0'

Use these implementations for paho mqtt in the build.gradle(:app)

implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.5'
implementation 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'

Add these permissions to the manifest:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

add this line to gradle.properties

android.enableJetifier=true

It worked for me. I hope works for you too.

After changing the version to Androidx, it does not become mqtt connect
