Current behavior

Hey,

while small files are working fine, when I select a big file (>~50MB) on Android, the plugin does not proceed.

The File picking overlay is showing up and I select a big file from the Downloads folder on my Android Simulator (Pixel 4 API 33 (emulator) (Pixel_4_API_33)). The overlay disappears and I'm back in my app. But there is no processing, no positive (sucess) or negative (error) outcome.

I tried with several file types, .mov, .csv, .pdf. My assumption is, as soon as the file exceeds a certain threshold file size, the plugin is not working. I added a link in the README of the reproduction repository for a file that is not working.

Current result: No event, no error, no feedback from the plugin

Expected behavior

Expected result: FilePicker retrieves data and calls its callback function, whether with file data (success) or with an error message.

Reproduction

Steps to reproduce

Run this capacitor app on an android device
Pick a big file (I wasn't able to narrow it down) I used sample_1920x1080.mov from https://filesamples.com/formats/mov

Yes, this is the expected behavior for large files if you set the readData option to true. The reason is that the file is loaded into memory as a base64 string and the available amount of memory is limited. This then leads to a crash. You should set the readData option to false. Feel free to take a look at our File Handling Guide for Capacitor for more information.
