Low Memory error on Android 10

[wimZ]

ScanDoc after the camera finishes, sometimes comes with a Low Memory warning. It seems related to the complexity/darkness of the image. the app does not crash since the library fix (4.2.5), but continues after a tap/back. I have tried with image-quality 1 and 2.5 with the same result.
I never observed this issue on Android 9, but it appeared after upgrading to Android 10.

This is the error message

Versions:

• Scandoc version 4.2.5
• Cordova Version: 9.0.0 (cordova-lib@9.0.1)
• Cordova Platform: Android 8.1.0
• Device OS: Android 10
• Device: Samsung S9

If there any additional info or assistance is needed, please let me know. I appreciate any suggestions.

[atebsy]

I have observed the same issue on my side

[ChrisTomAlx]

This issue has to be fixed in the library. Not sure when I will be able to take a look at it though. This is a good starting point anyone trying to tackle this issue.

Cheers, Chris Neutrinos

[ChrisTomAlx]

There is no timeline as of now. So I don't really have an immediate answer for you. But I can look at any PRs that are raised to address this issue.

1. add this plugin to your project "cordova plugin add cordova-plugin-document-scannner".
2. build it once .
3. Download the scanlibrary from Neutrinos github repository ( I used scanlibrary -2.5). link:- click here https://github.com/NeutrinosPlatform/scanlibrary/tree/v2.5
4. unzip the scanlibrary
5. open with android studio
6. wait for gradle sync to finish
7. add required sdks and build tools ( You can otherwise edit the version inside "library/build.gradle" file to adjust it to your available sdk and build tool ).
8. restart the Android studio.
9. wait for gradle sync to finish.
10. Build your project
11. after successful build you will get a 'library-debug.arr' inside the "library/builds/outputs/arr/".
12. copy that file.
13. Go to "C:\Users\USER_NAME.gradle\caches\modules-2\files-2.1\com.github.NeutrinosPlatform\scanlibrary\2.5\6209d26ba4ea44188835ca326adb4a3db9cfd7af" (since this is a temporary directory name will vary from system to system , you can apply a search in windows search tool using keyword "scanlibrary-2.5.aar"(version name varies)).
14. Paste your "library-debug.arr" inside it .
15. copy the name of previous '.arr' file present inside the directory.(ex. scanlibrary-2.5.aar ) .
16. Delete the previous file (ex. scanlibrary-2.5.aar).
17. Rename your copied file (library-debug.arr) to (scanlibrary-2.5.aar).
18. Thats it ! 💯 💯 🥇 You can also change the code according to your requirement . Thank Neutrinos platform for such beautiful library Enjoy Your patching .Now your patching done There should be no "Low Memory" warning after this. (TESTED OK ,ANSHUMAN NAYAK ,CTO N3XVERSE PVT.

Are You sure , because I have tried and using this in my application without any error

Don't forget to build your SDK after editing the library

Can you provide the portion you edited.

[SeaEagleEye]

It's not working in Android 10, Samsung Galaxy J8 mobile after taking picture it's showing black screen

[davidquon]

I'm having the same black screen problem as https://github.com/NeutrinosPlatform/cordova-plugin-document-scanner/issues/74#issuecomment-688596560 running Android 10 on a Samsung Galaxy S9. I'm using Ionic and Cordova with this plugin.

Ionic CLI         : 6.11.8
Cordova CLI       : 10.0.0
Cordova Platforms : android 9.0.0, ios 6.1.0

[SeaEagleEye]

remove platform android and run ionic cordova platform add android@8.0.0

[davidquon]

remove platform android and run ionic cordova platform add android@8.0.0

@SeaEagleEye Do you know what the issue is requiring moving back to 8.0.0?

No It's just a quick fix

Does using cordova-android 8.0.0 fix this issue for you as well @davidquon? Don't have a device to replicate this issue so would appreciate it if you could get back on the status.

Cheers, Chris Neutrinos

[wimZ]

For me it works on android 8.0 using android-targetSdkVersion: 29

[wimZ]

Unluckily it does not work on 8.1.0, and that is the version that enables application bundles (.aab)

[ChrisTomAlx]

That is really strange. I will try and pick this up as soon as work on the plugin starts again

Thanks for all the testing you guys have done :)

Cheers, Chris Neutrinos

[NautamSanghani]

Can you implement multi scan functionality If you implement that will be great

@NautamSanghani please don't hijack issues. There is another similar issue #31 . You can leave your thoughts there. It has already been considered as an enhancement but not sure when we will get around to it.

Cheers, Chris Neutrinos

[benediktcarda]

I can confirm the observation of SeaEagleEye that the plugin shows the black screen after taking the picture. Anyway reverting to cordova platform Android 8 did not solve the issue for me.

[ChrisTomAlx]

Released a new beta version of the plugin.

To test it :-

1. Make sure to remove the old version using cordova plugin rm cordova-plugin-document-scanner
2. To test it add the following to your project
   • cordova plugin add cordova-plugin-document-scanner@5.0.0-beta.0
   • cordova plugin add cordova plugin add cordova-plugin-androidx
   • cordova plugin add cordova-plugin-androidx-adapter

If you guys could help by testing this beta version and let me know if it solved your issue, I can release the 5.0.0 version. Latest plugin also solves this issue

Cheers and have a nice day :) Chris Neutrinos

[wimZ]

Thx, I'll go test later this week.

[ChrisTomAlx]

Thanks @wimZ Appreciate it :))

Cheers, Chris Neutrinos

[benediktcarda]

I tested the beta but the behaviour does not change. After taking the photo it still shows the black screen like SeaEagleEye showed on 8 Sep.

Additional information, but probably not a problem. When adding the plugin "cordova-plugin-androidx" I get the following output:

cordova plugin add cordova-plugin-androidx Installing "cordova-plugin-androidx" for android Plugin doesn't support this project's cordova-android version. cordova-android: 9.0.0, failed version requirement: <9.0.0 Skipping 'cordova-plugin-androidx' for android Adding cordova-plugin-androidx to package.json

Seems like cordova android 9.0 doesn't need cordova-plugin-androidx?

[wimZ]

I just tested it as well.

I get a scanDoc error result ‘incorrect result or user cancelled the action’

Are there minimum version dependencies?

Regards, wim

[ChrisTomAlx]

@benediktcarda @wimZ Could you guys add the following to config.xml as suggested by this comment and see if the issue persists?

<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">
   <application android:usesCleartextTraffic="true" android:requestLegacyExternalStorage="true"/>
</edit-config>

Also @benediktcarda it does not matter that cordova-plugin-androidx is deprecated, just add it nonetheless and add the other one too. You can ignore the deprecation notice and continue.

Cheers, Chris Neutrinos

[wimZ]

On first try it works!

I’ll do some more testing later

Thanks

[benediktcarda]

After adding

`

`

it started to work again (I can crop the scanned pages and save to my application), but now I get the low memory message wimZ reported initially.

[ChrisTomAlx]

@wimZ If possible when you reply via email click the 3 dots and remove the history then respond. I have edited your comments and removed the unnecessary reply quotes for now. Also thanks for helping with the testing :). Let me know if you face any other issues in your testing. I will also fix this need to request legacy storage before I release ver 5.0.0.

@benediktcarda Is it just showing low memory error and then you are able to scan normally? or low memory then it just keeps opening up the camera UI over and over again until app crashes? If you are able to continue normally it might actually be an issue with memory and this is expected behavior. Either way let me see what I can find and thank for testing the beta version :)

Cheers, Chris Neutrinos

[onlyplaytama]

hi @ChrisTomAlx ..

i saw in your scan library

createdirectory when opencamera is not working with API 29

already try run with your scanlibrary 3.2 still not working

Update : i found that Storage permission are not Allowed , already put <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> in AndroidManifest.xml but its not working , after i turn on allow manually from setting->apps->permision . its working

reg, tama

I also get the "Incorrect result or user cancelled the action" message when I take a photo.

Adding android:requestLegacyExternalStorage="true" to the AndroidManifest.xml seems to fix the problem but idk if this is a viable solution as @ChrisTomAlx noted here https://github.com/NeutrinosPlatform/cordova-plugin-document-scanner/issues/82#issuecomment-725231041

[ChrisTomAlx]

@sergiuturus Released 5.0.0-beta.1 of this plugin with the fixes. Let me know if this fixes your issue.

To test it :-

1. Make sure to remove the old version using cordova plugin rm cordova-plugin-document-scanner

   • cordova plugin add cordova-plugin-androidx-adapter

Cheers and have a nice day :) Chris Neutrinos

[ChrisTomAlx]

@onlyplaytama You could try and use the diagnostic plugin to manage permissions.

Cheers and have a nice day :) Chris Neutrinos

Still showing the low memory message, but in the end the scan is made. I am using cordova android 9.0.0 so i did not install the AndroidX plugins, because they are not compatible with version 9

[HerickRaposo]

@sergiuturus Lançado 5.0.0-beta.1 deste plugin com as correções. Avise-me se isso resolver o seu problema.

Para testar: -

1. Certifique-se de remover a versão antiga usando cordova plugin rm cordova-plugin-document-scanner

2. Para testá-lo, dependerá do seguinte ao seu projeto

   • cordova plugin add cordova-plugin-document-scanner@5.0.0-beta.1
   • cordova plugin add cordova-plugin-androidx
   • cordova plugin add cordova-plugin-androidx-adapter

Saúde e tenha um bom dia :) Chris Neutrinos

I solved the exclusion problem using the cordova file plugin.however I was unable to remove the low memory message. How can I hide it? Do you have a solution? If so tell me where I should modify that I even fork or branch

can some one give me the code to get Base64 of image in Pictures. path : file:///storage/emulated/0/Pictures/my_image.jpg am trying to get base64 string from Base64 & File plugins but through both the approach am getting null outpot

[benediktcarda]

The problem that after taking a picture it's showing a black screen is back. Got it reported from a user and tried it myself. When having the blank black screen you can do nothing but either click on the camera icon and take another photo (which again leads to the black screen) or you can click on the folder icon, choose another photo from the gallery and even manipulate the edges but as soon as you click "save" you get the error:

open /storage/emulated/0/Pictures/Title - Sun Mar 13 16-23_45 GMT+01_00 2000.jpg: open failed: EACCES (Permission denied)

[Dbouwheer]

@ChrisTomAlx : just a thought, but i do not have any app building experience.

The error pops up just after the "cropping/automatic edge selection" stage. It seems to me that the “cropping” is done while the photo taken is still in high quality. Is this a very memory intentive task? Otherwise maybe descaled the image to a lower quality before this stage. Instead of adjusting the quality in a later stage.

Will delete the comment if i'm talking nonsense ;)
