In this article, we’ll explain in simple words how to decompile an APK using MT Manager, what it means, how it works, and what you can do with it.

What Is Decompiling an APK?

An APK is the file type used by Android apps. It contains everything the app needs: code, images, layout, text, and other files.

Decompiling means opening the APK so you can see what’s inside and even edit it. When you decompile, you turn the app’s compiled files into readable and editable files. This is useful for:

Checking how an app works.
Translating the app into another language.
Customizing or modifying for learning.
Fixing small bugs or changing icons.

Decompiling is often used by developers and Android learners to understand app structures better.

What Is MT Manager?

MT Manager is a powerful file manager and app editor made for Android devices. It’s used for editing APKs, changing text files, managing folders, and more. Unlike many other tools, you can do everything directly on your phone, without using a PC.

Some of its main features include:

Viewing and editing APK files.
Decompiling and recompiling apps.
Editing Smali code and XML files.
Translating app strings into different languages.
Changing icons, package names, or layouts.
Managing files easily with two side-by-side panels.

Why Decompile an APK?

People decompile APKs for several reasons:

Learning: To see how Android apps are made.

Editing: To fix small issues or change visuals.

Translation: To make an app available in your local language.

Customization: To modify colors, layouts, or text.

Debugging: To check and fix app logic for your own projects.

How to Decompile APK Using MT Manager?

Follow these simple steps carefully to decompile any APK file with MT Manager.

Install MT Manager

Download the latest version of MT Manager from the official website or a trusted source.

Install it on your Android device.

When asked, allow storage permissions so the app can access your files.

If you want to edit system apps, you may need root access, but for most normal APKs, root is not required.

Open MT Manager and Find the APK

Launch MT Manager.

The app has two panels you can browse two folders at the same time.

On one side, go to the folder where your APK is located.

Tap the APK file once.

Choose the “Decompile” Option

When you tap the APK, a small menu will appear. You’ll see options like: View, Decompile, Sign, Clone, Copy, and choose “Decompile”.
MT Manager will now unpack and decompile the APK. It may take a few seconds, depending on the file size.

Explore Decompiled Files

Once decompiled, you’ll see several folders and files such as:

res/ → contains app layouts, images, and strings.

smali/ → contains the app’s logic and code.

AndroidManifest.xml → describes app permissions and name.

You can open any of these files to explore or edit them.

Edit Files (Optional)

You can now make changes inside the app:

Edit strings.xml to translate text or change words.

Edit AndroidManifest.xml to change the app name or permissions.

Edit Smali code if you know what you are doing (for advanced users).

Replace images in the res folder to change app icons or layouts.

Make sure you do not delete or rename important files. Always keep a backup before editing.

Recompile the APK

After editing, it’s time to rebuild your modified APK.

Go back to the main folder.

Long-press the decompiled folder.

Choose “Recompile” from the menu.

MT Manager will rebuild the app and show a message like “Recompile Success” when it’s done.

Sign the APK

Every Android app must be digitally signed before you can install it.

After recompiling, tap the APK again and select “Sign”.

MT Manager will create a new signed APK automatically.

You can now install it on your phone.

Key Features That Help in Decompiling

Dual Panel Interface: Work on two folders easily.

In-App Editors: No need for another app to edit XML and Smali directly.

Fast Decompiling: Works quickly even on big APKs.

Dex Editor+: Helps modify app functions in-depth.

Zip and Text Viewer: Preview content without extracting.

Tips for Safe Decompiling

Always back up the original APK before making changes.

Don’t modify apps that are not yours or belong to paid developers.

Use MT Manager for learning or personal use only.

Avoid editing system apps unless you know what you are doing.

If recompilation fails, check that all folders and file names are correct.
