Gradle: Exclude file from Android assets folder

Question

Please, do you know a way how to exclude some file from Android project assets folder before multiple assets folders are merged or during the merge?

For example:

android {
  sourceSets {
    main {
      assets.srcDirs = [fileTree(dir: 'assets1', exclude: 'myfile.txt'), 'assets2'] // does not work
      assets.exclude 'assets1/myfile.txt' // does not work
      assets.exclude '**/*.txt' // does not work
      assets.exclude '*.txt' // does not work
    }
  }

  packagingOptions {
    exclude 'assets1/myfile.txt' // does not work
    exclude '**/*.txt' // does not work
    exclude '*.txt' // does not work either
  }


  aaptOptions {
    ignoreAssetsPattern "myfile.txt" // does not work
  }
}

FYI: `assets.srcDirs = [fileTree(dir: 'assets1', exclude: 'myfile.txt'), 'assets2']` does not work. — Blackhex, Oct 22 '14 at 10:49

I run into the same problem and it seems adding a "!" works to indicate the file should be excluded:

aaptOptions {
    ignoreAssetsPattern "!myfile.txt" 
}

"assets.exclude" might work also by adding a "!" but I haven't tested it...

use `*` for wide char, and use `:` to split patterns. like: **"!*.txt:!*.rtf"** – Behrouz.M Jun 11 '16 at 10:51
! indicate about suppressing warning. Docs: https://android.googlesource.com/platform/frameworks/base/+/6d2c0e5/tools/aapt2/Files.h#88 – Ivan Shafran Jun 04 '20 at 14:52
Not sure if the docs you mention are related or wrong? I just double-checked and the '!' does indeed ignore the assets. I am aware it's odd, but that's just how it seems to be implemented. – noblemaster Jun 05 '20 at 15:13

I think this should do what you want:

android {
    aaptOptions {
        ignoreAssetsPattern "myfile.txt"
    }
}

Cool, thanks, I will try that and accept your answer accordingly. – Blackhex Dec 17 '14 at 21:18

No, this also does not work. The error about duplicate files is thrown during ``mergeAssets`` stage while I think that ``aaptOption`` is applied during package stage. – Blackhex Dec 19 '14 at 09:53
Ok, I see... sorry them :/ – Noel De Martin Dec 19 '14 at 11:46

It's not possible at the moment.

The packagingOptions feature does not apply to Android resources or assets.

Thanks, I'll try to experiment with dependency on Copy task or FileTree first before I'll give it up... – Blackhex Sep 19 '14 at 16:17

we can delete files/folders after build.gradle has finished its internal task of merging all assets .

android.applicationVariants.all { variant -> }

this is the loop where many android build tasks(in groovy language) are offered.

so in this case mergeAssets.doLast is the groovy task where we can perform delete operations.

here i used code to delete a zip file and images folder

tested on Android 3.1.4

hope it helps

android.applicationVariants.all { variant ->

if (variant.buildType.name == 'release') {

    variant.mergeAssets.doLast {
        println("deleting item.zip', 'images/**' from variant")
        delete(fileTree(dir: variant.mergeAssets.outputDir, includes: ['item.zip', 'images/**']))
    }
 }
}

Try this:

export ANDROID_AAPT_IGNORE="ignoreAssetsPatternThatActuallyWorks"
./gradlew assembleDebug

It's the only way to influence the mergeDebugAssets step (code found here).

Filed a bug about this.

To protect assets folder information If the html file is either css or js, the easiest way is to: Write your code in the html editor first, and then enter it in a Java class as follows :

 public class Content{
    public static final String  myContent ="<!DOCTYPE html> ... </html> "

And then call through the loadDataWithBaseURL method

 webView.loadDataWithBaseURL(null,Content.myContent, "text/html" , "UTF-8" ,null);

And you can call js and css in html code :

 ...
 <head>
 <link rel="stylesheet" type="text/css" 
  href="file:///android_asset/css/custom.css" /> 
 <script src="file:///android_asset/js/code.jquery.js"></script>                                                                                   
</head>
