General questions

1.1 Is it necessary to purchase an Android tablet to try the app?

No, you can install the application on any smartphone or tablet with Android 4.2 or newer. You can also ask a friend who has an Android phone to install it so you can test it. The app can then be removed in a matter of seconds (like any other app).

If there is absolutely no way for you to have access to an Android device you can install an app player on your PC or Mac, for example Bluestacks.

1.2 Is it necessary for the user to have WiFi or Internet connection after installing the app?

No. Internet connection is not necessary for running the application. The books are transferred from a computer over a USB cable so the device works more or less like any portable audio player.

In fact I encourage disabling WiFi when "building" a dedicated player so that it lasts longer on a single battery charge.

1.3 I would like to make a Homer Player tablet but will I be able to do this with a Mac?

Yes, you can use a Mac or a PC with Windows or Linux.

1.4 When I browse books, the titles are not read aloud. How do I fix it?

The Text-to-Speech (TTS) module isn't working correctly.
There may be a number of reasons:

  • voice data for your language is not installed,
  • your language is not supported by your TTS module,
  • no TTS is installed on your device.

Go to Settings → Language & input → Text-to-speech output
Here you can choose the preferred engine, change its settings (e.g. download more voices) and play an example sentence.

Most devices come with the Google Text-to-Speech Engine installed. It supports a number of popular languages. If your language is missing (or you don't like the voice) you can install other TTS engines from the Play Store.
One engine with a large number of supported languages is Vocalizer (paid). You can also find TTS apps for specific languages.

1.5 How can I start a book from the beginning? While I was testing the book advanced 10 minutes and now I want it to play from start when I give the tablet to my uncle.

There is a function to reset progress on all audiobooks to the beginning.

  1. Start Homer Player.
  2. Tap the screen 5 times to open Settings.
  3. Choose "Rewind all books to the beginning…" and then confirm.

1.6 Can I put the audiobook files on a microSD card in the device?

The application scans all available storage types (both internal memory and any available SD cards). When it finds a folder AudioBooks in the top directory it adds all audiobooks to the list. This way books from an SD card and the internal storage are both available to the user.

Audiobooks compatibility

2.1 What audiobook formats are supported?

Homer Player supports DRM-free MP3 files.
Each book may comprise of a number of files that are played in alphabetical order. The files may also be nested in subdirectories (useful when copying books that come on multiple CDs).

This means that most audiobooks thay you buy will work fine.
However, subscription and rental services that only work with their dedicated application are unlikely to work.

2.2 Where do I get books to listen to with Homer Player?

There should be a number of sources available to you:

  • Stores: you can buy books in MP3 for download or on CDs from many internet stores like audiobookstore.com or Downpour (you probably know the best ones in your country).
    Look for DRM-free MP3 downloads.
  • Libraries: it's often possible to borrow audiobooks at the local library.
  • Free classics: there are many services and non-profit projects that provide free audiobooks (mostly classics).
    Here are a few that provide books in English:

2.3 Can I use audiobooks from Audible?

Unfortunately subscription services like Audible are not supported and they don't provide MP3 files for download.

See the previous question on some tips where to get books.

Installation on a dedicated device

3.1 When executing the adb shell command (step 8 of the instruction) I get the following error: device not found

If you get this error on a Windows computer then it's probably a problem with a driver for your tablet. Installing a universal ADB driver should help.

3.2 When executing the adb shell command (step 8 of the instruction) I get the following error: java.lang.IllegalStateException: Trying to set device owner but device is already provisioned.

This means that there are some accounts still configured on the device. Make sure you have performed step "5. Remove all accounts" correctly.

Supporting the project

4.1 How can I help with the project?

There's a number of ways you can help:

  • send me your feedback so that I know what needs improvement,
  • rate the app to make it easier to find by others,
  • translate the Google Play Store description to your language, it's just a few paragraphs long and may help others learn about the app (e-mail me for the English text),
  • tell others who might have a use for it.

Any help is appreciated, thank you!

4.2 Can I donate money to the project?

Thank you, but there is no need. The project doesn't require much funds, it mostly needs my time and motivation.

If you want to show your appreciation the best way is to send me a postcard from where you live.
