cannot find symbol class BR?? Errrrrr……Where is the ERROR ?

File →Invalidate cache is not a solution for every problem especially when it comes to incognito mode errors :P . Errors that won’t show up in android studio.

Why?
There is a limit(or rather i would say default ) enforced by javac compiler to show only 100 errors.

but luckily can be modified by passing an argument to the compiler as mentioned below.

Solution : add this to your top-level build.gradle file.

allprojects {
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xmaxerrs" << "4000"
            options.compilerArgs << "-Xmaxwarns" << "4000"
        }
    }
}

Enjoy :)
