J2AMP - Apple Music Player for J2ME

J2AMP is a proof-of-concept but also very fully-featured music player for Apple Music (AM)

Technically supports all devices with CLDC 1.1, MIDP 2.0 with JSR-75 and JSR-135 and HE-AACv2 support, however due to Widevine DRM playback, device with large RAM/heap are required.

Currently tested on an Nokia E72 / J2ME Loader emulator.

User instruction

• Your phones need to be cracked to install necessary TLS libraries. More information look at here
• Get your Apple Music credentials and save it as a .json file. You can get these from the Apple Music Web Player:
  • 1. Open https://music.apple.com in your PC's browser
  • 2. Log in and open the Console tab in the Web Inspector (F12 or CTRL+SHIFT+I)
  • 3. In the Web Inspector, go to the Console tab and paste:" JSON.stringify({ devToken: MusicKit.getInstance().developerToken, userToken: MusicKit.getInstance().musicUserToken })
  • 4. Copy the output JSON and save it as a .json file on your phone
• Install the correct file in ./dist into your phone.
  • For S40/ S80 / Sony Ericsson phones ..., upload the JAR file in the root directory to https://gtrxac.fi/fh and install the return signed file with your phone's browser.
  • For S60v3 FP1 phones or older / J2ME emulators, just install the JAR file in the root directory with your phone's file manager.
  • For S60v3 FP2 phones (maybe also newer Symbian devices, e.g S60v5, Symbian^3, ...), install the JAR file from the .\SYMBIAN9_3 folder with your phone's file manager. (this is just to bypass the pesky internet selection dialog)

Build instructions

• Install NetBeans 7.4 from here and the ProGuard library from here.

• Get the following files and put it into /res:

  • client_id.bin and private_key.pem from a Widevine-authorized device. I won't provide it in the source code, but you can look it up how to get them. Convert the private_key.pem to private_key.der: openssl rsa -in key.pem -outform der -out key.der
  • LastFM's API token and secret key, formatted as lastfm_token.json.

  {"apiKey" : "<your api key here>",
  "sharedSecret" : "<your shared secret key>"}
  

• Build the binary

FAQ:

• Will you ever add offline playback: well technically possible, adding them would be very risky legally for me so NO.
• Can you add other features such as X, Y, Z: maybe if I have time and if it is feasible; PRs are of course, always welcome :)
