This library is developed based on AOSP structure of androidfw/ResourceTypes.h , to totally replace aapt/aapt2
- Resource table (resources.arsc)
- Binary xml files (AndroidManifest.xml & resource xml)
- Decodes resources to readable json
- Encodes/Builds sources in json format to binary resources
- Decodes resources to source code
- Encodes/Builds source XML to binary resources
1- Decoding resources to XML requires all source names should be un-obfuscated and valid
2- User of this lib is assumed to have good knowledge of android source XML syntax, thus
during encoding/building it does not validate or throw XML syntax errors as often as aapt/aapt2. For
example, you are allowed to set wrong values on some places and doesn't prevent from
successful building. On AndroidManifest.xml you can set package="Wrong 😂 (package) name!"
then you have to know such values are acceptable by android devices.
