What is 1.apk that I see in output ?

[adrianTNT]

While unpacking an apk file with something like:

java -jar apktool_2.9.0.jar --frame-path /temp/ decode my_file.apk -f -o /temp/my_apk_unpacked/

I see this line in the output:

I: Loading resource table from file: /temp/1.apk

• What is the 1.apk file ? Does it show as an error or just a log ?
• Is that generated as partial output of each unpacked apk file ?
• Meaning ... is it a problem if two apk files unpack at the same time with same --frame-path ?
• Will there be a conflict with that 1.apk file ?

Thank you.

• Its the internal framework file copied out of the Apktool jar into a location for reference by aapt/aapt2 during compilation. (https://apktool.org/docs/in-depth/frameworks)
• Its only generated once if the file doesn't exist, however tagging or redirection of frame-path location may change this. Future version of Apktool may understand what version of the framework exists to prompt updates
• I haven't actually tested if concurrency becomes an issue in a situation where the framework files does not yet exist. So let me know.
• I don't know
