Can not access file system with new sdk versions

This commit seems to break the access to the file system. We found we were unable to access the apks anymore (Freedom of Computing app) without downgrading to target- and compilesdkversion 29

Could you please post the exact error or more detailed please? We want to reproduce..
The Google Platstore is forcing us to upgrade to this SDK level, otherwise we're kicked out 😢

Could be a possible fix for your problem: #91

Hi, the error we see is the below:

Suppressed: java.io.IOException: No original dex files found for dex location (x86) /storage/emulated/0/Download/act.apk
        at dalvik.system.DexFile.openDexFileNative(Native Method)
        at dalvik.system.DexFile.openDexFile(DexFile.java:367)
        at dalvik.system.DexFile.<init>(DexFile.java:109)

This can be replicated by trying to execute any apk inside the freedom-of-computing app.

We believe that the issue is caused by the storage updates in Android 11

Currently, requestLegacyExternalStorage is set in the app's manifest however, starting SDK Version 30 this flag seems to be ignored in Android 11. Hence, if we are required to upgrade the SDK it seems like the right direction for us to look at would be to either use scoped storage and require users to use the application's data directories or to use ACTION_OPEN_DOCUMENT and ask the user to provide us permission to use the file.
