I want to open a file from storage then read content and handle data further.

I added permission to AndroidManifest.xml

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I tried to find guide from Android but it just let me know about name of file or size
text

Currently, I copy file to /storage/emulated/0/Android/data/[my.package.path] and open by name but my application need to use file from user choosing.

file = new File(context.getExternalFilesDir(null), FILE_NAME);
Workbook workbook = WorkbookFactory.create(new FileInputStream(file));
