how to call an activity from a library android

I'm trying to call an activity that is in the main project from a library

Library code

Intent in = new Intent(this, com.process.agenda.activity.MainActivity.class);
startActivity(in);

Error:Circular reference between projects: :app -> :autenticadorCadastro -> :app

Main project

apply plugin: 'com.android.application'

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'

    compile project(':autenticadorCadastro')
}

Library

apply plugin: 'com.android.library'

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'

    compile project(path: ':app') // here throws the error
}

Thanks

You have to use one of the other methods of creating an intent. Usually I do it by apk name and activity name (passed down from the calling app, or put into strings resources that are overridden by the app if its an internal only library).

You shouldn't be able to. If you needed to call into your main project from your library then the project is a dependency of the library which flips things the wrong way. If you're making a library it should only depend on itself and other libraries.
