buildozer.spec and android.permissions = WRITE_EXTERNAL_STORAGE fails compile

[Gary Kuipers]

When I reinstall my app I lose access to photos stored by the app. If I erase and reinstall it asks for the other permissions (CAMERA, GPS, AUDIO but not the STORAGE permissions.  NOte that my app does NOT ask for audio but the buildozer.spec does, su it must come from there

The solution, so they say, is to add WRITE_EXTERNAL_STORAGE to android.permissions

No such luck:

when I  buildozer -v android debug I with the buildozer.spec that includes the line:

    android.permissions = WRITE_EXTERNAL_STORAGE

I get the following error:

Command failed: /home/gary/PycharmProjects/YSI_Read/venv/bin/python -m pythonforandroid.toolchain apk --bootstrap sdl2 .... etc.

The only difference in source is the presence/absence of that one permission.

 

Any ideas?

WRITE_EXTERNAL_STORAGE is not the solution on any modern Android device.

If you want persistence between app new installs use shared storage

If you want persistence between app updates use the app storage directory

On re-reading your question, I wonder if my answer was off target? In which case I didn't understand the question.

Anyhow, I have taken to logging my posts to a notepad just in case this happens. First post was long and detailed. Second post was shorter. This one will be really short.

From my reading: I'd like you to check my logic.

1) I thought the debug +  adb install -r bin/*.apk was an update. It is an install. This explains files and jsonstores becoming inaccessible when iterating compiles.

2) Private is a filesystem. androidstorage4kivy is built on Private. Jsonstore is on private. I can expect any of these to become inaccessible when compiling new version in development.

3) My conclusion is that during development I should only use androidstorage4kivy Shared. 

Is this correct?

1) its is an 'install update'

2) the lifetime of private files depends where they are located https://github.com/Android-for-Python/Android-for-Python-Users#private-storage

3) 'should' I can't say,

'could' yes,

'must' no.
