Android设备通过ADB提取完整APK的问题咨询

Hey there, let's break down why your pulled APK is way smaller than the one on APK Mirror and how to fix this issue!

Why is the size so different? #

The core reason here is modern Android apps often use App Bundles (split APKs). When you download an app from Google Play, it only installs the components your specific device needs—like a base APK plus split APKs tailored to your CPU architecture, screen resolution, or language. The version on APK Mirror is usually a universal bundle that includes all these components, hence the much larger size. When you ran adb pull /data/app/com.twofasapp/base.apk, you only grabbed the base APK, not all the split files that make up the complete app.

How to pull the full set of APKs #

First, let's confirm if the app uses split APKs. Re-run this command:

adb shell pm path com.twofasapp

If you see multiple lines starting with package: (e.g., package:/data/app/com.twofasapp/base.apk, package:/data/app/com.twofasapp/split_config_arm64_v8a.apk), that means it's split into multiple APK files.

Here are two reliable ways to pull all of them:

Option 1: Batch pull via command line

• Linux/macOS:
  Open your terminal and run this loop to pull every listed APK path automatically:

  adb shell pm path com.twofasapp | sed -e 's/package://' | while read line; do adb pull "$line"; done
  

• Windows (Command Prompt):
  Use this command sequence to grab all APKs:

  for /f "tokens=2 delims=:" %i in ('adb shell pm path com.twofasapp') do adb pull %i
  

• Windows (PowerShell):

  (adb shell pm path com.twofasapp) -replace 'package:', '' | ForEach-Object { adb pull $_ }
  

Option 2: Merge splits into a single universal APK (optional)

If you want a single APK file like the one on APK Mirror, you can merge the split APKs using bundletool (a Google official tool). First, collect all pulled APKs into a folder, then run:

bundletool build-apks --output=universal.apks --mode=universal --apks=/path/to/your/split/apks/folder

Rename the generated universal.apks to universal.zip, unzip it, and you'll find the single universal APK inside.

Bonus: Check for OBB expansion files #

Some apps have large OBB (expansion) files for extra content. You can check if your app has them by looking at this path:

/sdcard/Android/obb/com.twofasapp/

If files exist there, pull them with:

adb pull /sdcard/Android/obb/com.twofasapp/

After following these steps, you'll have all the files that make up the full app, matching the total size you see on APK Mirror!
