DensityScaler

Enhance your Android app by dynamically resizing it through density adjustments using this simple tool.

Edit the Scale Amount

Java

Modify the scaling factor by editing DensityScaler.java. Change the value 0.7f to your desired float value:

float scale = 0.7f; // Replace this value

Smali

To change the scaling factor in Smali code, update the following line in DensityScaler.smali:

const v2, 0x3F333333    # 0.7f

Replace 0x3F333333 with the corresponding hexadecimal value from the table below.

Using the Java or Smali Files

1. Add Files to Source Code: Place the provided files in the /com/dpi/ directory within your app's source code.
2. Update AndroidManifest: Include the following provider in AndroidManifest.xml:

   <provider
       android:authorities="your.app.name.com.dpi.DensityScaler"
       android:exported="true"
       android:name="com.dpi.DensityScaler" />

   Note: Replace your.app.name with your app’s package name.

Using the Precompiled classes.dex

1. Decompile Without Source Code:

   apktool d -s name.of.apk

2. Add Precompiled Class File: Rename the precompiled classes.dex file to the next available classesX.dex, such as classes2.dex or classes8.dex, and add it to the decompiled APK.
3. Update AndroidManifest: Include the following provider:

   <provider
       android:authorities="your.app.name.com.dpi.DensityScaler"
       android:exported="true"
       android:name="com.dpi.DensityScaler" />

   Again, replace your.app.name with your app’s package name.

Smali Float Values

Use the table below for converting decimal scaling factors to hexadecimal values:

Decimal	Hexadecimal
0.35	0x3EB33333
0.4	0x3ECCCCCD
0.45	0x3EE66666
0.5	0x3F000000
0.55	0x3F0CCCCD
0.6	0x3F19999A
0.65	0x3F266666
0.7	0x3F333333
0.75	0x3F400000
0.8	0x3F4CCCCD
0.85	0x3F59999A
0.9	0x3F666666

By following these steps, you can successfully scale your Android app and fine-tune it for different density preferences.
