Is there a way to create and save text files outside of the Android/data folder in external storage? I am creating a music app and I added a preset manager so users can save, load, and edit preset files (which worked great before Android 11), I don’t want these files to be automatically removed if the app is uninstalled. That would be like if Photoshop deleted all of your Photoshop documents when Photoshop is uninstalled, that’s terrible! These are files that the user saves and they can be deleted separately if the user wants to.

There has to be a way around this but I haven’t been able to find anything that works. ACTION_OPEN_DOCUMENT_TREE looked very promising, until I saw that Android has removed this option too.

https://developer.android.com/about/versions/11/privacy/storage

You can no longer use the ACTION_OPEN_DOCUMENT_TREE intent action to request access to the following directories:

• The root directory of the internal storage volume.
• The root directory of each SD card volume that the device manufacturer considers to be reliable, regardless of whether the card is emulated or removable. A reliable volume is one that an app can successfully access most of the time.
• The Download directory.

I’ve read Google Play only allows MANAGE_EXTERNAL_STORAGE in apps that need it (like file browsers, or anti-virus, etc) which likely will not work in my case. I don’t want to rely on only targeting older API’s so requestLegacyExternalStorage won’t work either.

Everything I’ve looked into appears to be a dead end. Is there anything else I can do?

Here is a short test program (I’m using LibGDX), which at the moment can only save to the root location:

I tried to use ActiveSupport::Cache::FileStore dirctly in a model class:

I'm trying to convert a csv spreadsheet into a double 2D array. I have managed to convert the csv into a 2D string array. I am now trying to convert that into a double. I am getting a NumberFormatException I believe this is because when I try to Double.parseDouble, it keeps reading the column header which is a string. It may also be the commas in my csv? Not sure what my next steps are.

I am having trouble using Java to identify and replacing a specific character that appears in a text file I have. It is a non-printable character, but it seems that Java renders it as – when outputting to the console.

It seems to be this character: https://www.fileformat.info/info/unicode/char/c296/index.htm

Here is what I have done:

1. I made a copy of the file and deleted everything from it except for the single character that I am struggling with.
2. Opened the file in UltraEdit. It appeared to be an empty file.
3. Changed UltraEdit to "hex mode", now it shows up as two characters: – with a hex value of 0xC296 (or "C2" for the  character, and "96" for the "–" character).
4. I wrote the Java program below in an effort to change this character to something printable, but I have been unsuccessful.

Here is the code:

I am trying to write a regular expression for JavaScript.

I have file names with folders and I need to consolidate them from the git changes. e.g. Input:

I am developing an application with JWT authentication on the google cloud platform. Server side I added authentication via Cloud API Gateway to a cloud run backend. Now I am making a client to generate the JWT token and pass it in the call. To do this I am creating an application that must be deployed on CloudRun and I am following this documentation: https://cloud.google.com/api-gateway/docs/authenticate-service-account#making_an_authenticated_request. My problem is that I don't know how to indicate what it requires as saKeyfile. I tried to put only the name of the file that under src / main / resources / filetest.json but once I try to call the method it tells me file not found. I tried to indicate also the full path. Can anyone help me?

PS I'm using Java

EDIT: here is my code which is the same of documentation

I have a database with comments, and I would like to create another database with just the comment which contains some specific words.

I know there is a function like contains but I would like to know how to do this on the entire database and extract only the comments with specific word in order to do some advanced analysis on those specific topics.

Do you have a way to do this ? I'm sure I have already saw that somewhere but I cannot find where.

Here's what's my database look like :

I obtained it with BeautifulSoup and this script :

I want to scrape all the comments on this website : https://fr.trustpilot.com/review/www.gammvert.fr

I would like to have the comment, the rating and the date. I managed to obtain the comment and the rating but not the date.

Here's my script so far :

I'm trying file I/O in C# (haven't done so at all before since I'm a beginner). I put a simple text file containing "some text" (literally) in the solution's resources, wrote some code based on online tutorials and pressed F5 to build. I was expecting "some text" to show up in the console window, but an exception did!
