How to Mod an Android App

[Tutorial] Making Your Own Android App

Actually, it's not really making! You could say it's modding. So let’s start!

Necessary Tools

First, decompile the APK using APKTOOL. Then locate these files:

Now, open apktool.yml and search for these lines:


Apk file name- Snigdho.apk

PackageInfo

Cur_package: com.bel.android.snigdho

Orig_Package: com.bel.android.snigdho

For example, change them to:


Apk file name- XaynoUI.apk

PackageInfo

Cur_package: com.xaynoui.app

Orig_Package: com.xaynoui.app

Now save it and open AndroidManifest.xml. Search for these lines:


package="com.bel.android.snigdho "

Change it to, for example:


package="com.bel.android.xayno "

Next, open smali/com/snigdho and rename “snigdho” to “xayno” so it looks like com.xayno.app. Save the changes. Your package name is now changed.

To change the app name, open AndroidManifest.xml and search for these lines:


<application android:label="@string/appname" android:name=".SnigdhoApplication">

Rename it to:


<application android:label="Xayno" android:name=".SnigdhoApplication">

Now open res/values/strings.xml and search for these lines:


<string name="app_name">Snigdho</string>

Rename it to, for example:


<string name="app_name">Xayno</string>

If you want to customize the app, open res/drawable-nodpi and customize the PNG files as desired.

Finally, recompile and sign the APK. Please refrain from app stealing, as this is not supported.
