You are using two JVM options that are no longer available in recent Java versions:

• The MaxPermSize option has been removed in Java 8
• The UseConcMarkSweepGC option was deprecated in Java 9

Both options were initially reported as a warning and now raise an actual error when trying to start the VM.

Unless you encounter specific issues, you should be able to rely on the current default values, so simply remove -XX:MaxPermSize=512m and -XX:+UseConcMarkSweepGC from your list of arguments (e.g. in your gradle.properties file).

You forgot to put the type of the variable. If should be NsdManager.DiscoveryListener discoveryListener = new NsdManager.DiscoveryListener() {

You're also going to have the same problem with nsdManager. And in your last function because you use discoveryListener without defining it. When you copy pasted this code from somewhere did you forget to copy paste the instance variables of the class?

Thankyou everyone. I changed my build environment from staging to debug and it worked. Now need to work on the newer problem of why the build environment is not working.

self answer.

In my case, after fixing the following code, the problem was solved.

To speed up the build I used the following code in gradle.properties:

Update the minSdkVersion:
