Android 10 (One plus phone) document scanner hangs and after some time crashes

[ndev10]

Code looks like this

` const opts: DocumentScannerOptions = {

  sourceType: DocumentScannerSourceType.CAMERA,
  quality: 5.0,
  returnBase64: true
};

this.documentScanner.scanDoc(opts)
  .then((imageData: string) => {
    this.uploadedDocuments.push(imageData);
    this.presentAddMorePopup(false);
  }).catch((error: any) => {
    console.error("need to run in device")
  });

` Even on lowest quality it hands and then crashes Please find below image

Hey @ndev10

Could you share the error stack trace from android studio?

Cheers and have a nice day :) Chris Neutrinos

Also observed the issue on SAMSUNG GALAXY S8 WITH ANDORID 9.

[ChrisTomAlx]

Hey @ndev10

Thanks for sharing the stack trace but I don't seem to see an error logged here.. Make sure the errors are being logged and copy the stack trace only after the app crashes so as to capture the final error causing app to crash

Cheers and have a nice day :) Chris Neutrinos

[vishnupriyads]

Hey @ChrisTomAlx

The same issue i am facing only in android 10 it is crashing. Other versions of android it is working. Please do the needful

[prasanth003]

@ChrisTomAlx

we are using this plugin for OCR. This plugin is worked in my previous version of android. After upgrading to android 10, i am not able to do document scanning. the app automatically closing. My Mobile Modal is REDMI K20

[ChrisTomAlx]

Hey @prasanth003 and @vishnupriyads

Please share error logs from android studio. I don't have an android 10 phone currently to test this.

Cheers and have a nice day :) Chris Neutrinos

[wimZ]

I have the same issue. When using sourceType: Camera, returnBase64: true, the symptoms are as described above; no error is thrown, the app continues without calling success or error function. When using sourceType: File, returnBase64: true; result is the same, but I do see the cropped image in a file.
I have no idea how to fix or debug a plugin, so rely on you for this. As Android 10 starts to roll onto Samsung now, I appreciate your support.

If necessary, I can assist if I know how.

Hope this can be fixed Kind regards, WIm

[ChrisTomAlx]

This issue has now been fixed in plugin version 4.2.5 Sorry about the delay This is what was causing the issue.. On the 33rd build the bitmap insertImage function used to fail/

Cheers and stay safe :) Chris Neutrinos

[wimZ]

I just upgraded my project to version 4.2.5. Unluckily the Low memory error still occurs on each scan.

[atebsy]

Hi @ChrisTomAlx ,

the issue on Android 10 is still persisting, this only happens when the sourceType is set to 1, once the scanner is open I can't go back to the app the camera hangs there, event without taking a picture and after eventually pressing the back button multiple times it goes back to the home page. And I have noticed that in the version 2.23 this works but intermittently (Sometimes it does and sometimes it does not) but on Version 2.25 it doesn't work at all it hangs all the time here is the android studio log:

I have the same issue. When using sourceType: 1, returnBase64: true. Error is: incorrect result or user cancelled the action.
