But when I use the emulator to do this, everything is fine.

Does anyone know why is it?

For security reason, it's not allowed.
You can do it only on emulator or rooted device.

But you can add needed files in assets, so these are included in APK.

build.gradle:

android {
  sourceSets.main {
    assets.srcDir '/absolute/path/to/your/assets/folder'
  }
}
