==XNB mods==
<div style="border: 1px solid red; background: #FCC; padding: 1em;">'''[[Modding:Using XNB mods|XNB mods aren't recommended]], are harder to install, and often break when the game updates.'''</div>
If you're sure you want to use them, here's how. {{collapse|content= 
===Obtain the APK===
First you'll need the APK (''Android Package'') file for your game, which contains the game files. Downloading the APK from third-party websites isn't recommended, since it'll often be outdated or contain malware.
There are two ways to access the APK file:
* If you have [https://www.androidcentral.com/root root access], it's located at <tt>/data/app/com.chucklefish.stardewvalley-1/base.apk</tt>.
* Otherwise install [https://play.google.com/store/apps/details?id=com.ext.ui APK Extractor] and run it. The APK will be extracted to <tt>ExtractedApks/Stardew Valley_com.chucklefish.stardewvalley.apk</tt> on your device.
===Install an XNB mod===
; Option A: MT Manager app on your phone
:# Copy the XNB files you want to install into a new folder on your device.
:# Install and open [https://play.google.com/store/apps/details?id=bin.mt.plus MT Manager] on your phone.
:# On the left side of the screen:
:## Find [[#Obtain the APK|the Stardew Valley APK]].
:## Tap it.
:## Select 'view'. This should open a folder containing the game's asset files.
:# On the right side of the screen:
:## Find the folder containing XNB mods (from step 1).
:## Make sure the corresponding folder is open on the left side of the screen (e.g. the <tt>Portraits</tt> folder if you're installing portrait mods).
:## Select the files to copy. (To select all, tap the '''<tt>⋮</tt>''' menu and choose 'select all'.)
:## Long tap the selected files, and choose the copy option.
:## A menu should appear. Change the 'level' option to Storage, and the 'update mode' to Replace All. Tap OK to copy the files.
:# On the left side of the screen:
:## Return to the folder containing the <tt>.apk</tt> file.
:## Tap on the Stardew Valley APK file, choose 'Function', then 'APK Sign'.
:## Tap the '''new''' APK file that generates and choose 'Install'.
; Option B: Android Studio on your computer
:# Install an unzip program like [https://www.7-zip.org/download.html 7-zip].
:# Install JDK 8.
:# Install Android Studio (make sure to install build-tools).
:# Install APK Signer Tool (v2).
:# Unzip [[#Obtain the APK|the Stardew Valley APK]] to your computer.
:# Replace the vanilla XNBs (found in <tt>./assets/Content/</tt>) with the modded XNBs.
:# Re-zip the contents of the Stardew Valley APK. Make sure not to include the container folder.
:# Change the file extension from <tt>.zip</tt> to <tt>.apk</tt>.
:# Open APK Signer Tool (v2).
:# Fill out all fields on the Keyfile Generator page (doesn't matter what you enter).
:# On the Align & Sign tab, select the modded APK file.
:# Select key and fill out the appropriate fields.
:# Click Align and Sign.
:# Wait a few moments.
:# Move the APK to the device and install.
===Install an audio mod===
# Download {{github|mariodon/unxwb/releases|unxwb}} and {{github|Microsoft/DirectXTK/releases|XWBTool}}.
# Unzip both to your working directory.
# Copy the <tt>.obb</tt> file from your phone's internal storage (located at <tt>Internal Storage/Android/obb/main.2.com.chucklefish.stardewvalley.obb</tt>) to your working directory.
# Run this command to unpack the file: <pre>unxwb main.2.com.chucklefish.stardewvalley.obb</pre> That should output 87 files with names like <tt>00000000.wav</tt>.
# Move the unpacked <tt>.wav</tt> files to a separate folder to keep things organised.
# Replace any of the audio files as desired (but the names must remain the same).
# Run this command to repack the file (replacing <tt>folderPath</tt> with the full path to the folder containing the <tt>.wav</tt> files): <pre>XWBTool "folderPath/*.wav" -o Music.xwb</pre> Note that the output file ''must'' be called <tt>Music.xwb</tt> when repacking.
# Rename <tt>Music.xwb</tt> to <tt>main.2.com.chucklefish.stardewvalley.obb</tt>.
# Move the modified <tt>.obb</tt> file back to your phone's internal storage (at <tt>Internal Storage/Android/obb/main.2.com.chucklefish.stardewvalley.obb</tt>).
# Enjoy your modified music!
Here's [https://docs.google.com/spreadsheets/d/1K3S8YDS4Tfe_LPtyXA9LaVM8edxvDFkwfNl-ql1kFGM a spreadsheet of unpacked <tt>.wav</tt> file names].
