Answer 1

DexGuard provides the option -encryptassetfiles to encrypt assets. It is documented in the DexGuard manual > Settings > -encryptassetfiles. The samples directory also contains a sample project that illustrates the feature.

Hi @eric, i have followed every steps written in dexguard ->manual_>settings>encryptassetfiles . i have run the sample directory also in release mode but still the assets files inside the asset folder is not encrypted. I don't know why this is happening ,can u tell me what am i doing wrong? – Antique

In my assets folder , i have only one .txt files which contained the a single text – Antique

i can easily get the assets content using apk tool – Antique

@Antique If you contact support, we'll work it out. – Whipstitch

Answer 2

I experienced this same problem and found the solution in the docs.

This means that your code must invoke the AsssetManager as follows: open("MyAssetFile").

If you are not loading your asset in that manner then Dexguard does not encrypt the asset.

For example, you must open your asset like this:

InputStream stream = context.getAssets().open("myAssetFile.html");

rather than

mWebView.loadUrl("file:///android_asset/myAssetFile.html");

You also need to ensure that you have set your dexguard config to encrypt your assets:

-encryptassetfiles assets/myAssetFile.html,assets/myOtherAssetFile.txt

Can you please elaborate on the usage? With an example maybe. Thanks ! – Hekate
