By putting android:debuggable="true" in your manifest file, application will go in debug mode, that's mean android will manage all logs file regarding your application. But make sure put it again false(or remove this tag) if application will going to live or for release mode.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <application android:icon="@drawable/icon"
        android:debuggable="true"

With the new Gradle build system, the recommended way is to assign this in the build types.

In your app module's build.gradle:

android {

    //...

    buildTypes {
        debug {
            debuggable true
        }
        customDebuggableBuildType {
            debuggable true
        }
        release {
            debuggable false
        }
    }

   //...

}
