Issue
I have just installed the filter but I am not able to run it
Every time I try to run it, I run into this problem
I tried to find the answer on the internet but could not find the answer
Some people said make changes to the gradle-wrapper.properties file
But he still did not answer
Solution
That project is very old and cannot be opened using newer Android Studio versions because Gradle 4 is obsoleted.
Please use Studio 3.x.
Or try to upgrade to Gradle 7+ by editing "build.gradle", but it could require other changes in gradle files and/or included libraries.
