Are you running termux as root? Wouldn't it be obvious that any program can access those directories with root permission? |

I am, I am also running my app as root, even confirmed with a whoami. I was surprised as well that I can't see all of the data directories when running my app as root, but Termux can do it no problem, so I'm not sure what's going on here. This also applies to some root file Explorer apps I saw, so this must be some new permission change in the Android system for newer versions. |

That's because of app data isolation that's engaged if an app uses
targetSdkVersion>= 30(Android11) in which/data/data/*of other apps do not exist in the mount namespace of the app, and only its own and specific whitelisted packages likegms. Termux app uses28currently so it's not isolated. You can disable it for all apps by runningsu -c "setprop persist.zygote.app_data_isolation false"and rebooting, at the cost of privacy. Or in other apps, runsushell with the-mm/--mount-masterflag.https://cs.android.com/android/platform/superproject/+/android-14.0.0_r1:frameworks/base/services/core/java/com/android/server/am/ProcessList.java;l=2305
