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 ([email protected])
• 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

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.

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

remove platform android and run ionic cordova platform add [email protected]

[davidquon]

@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 [email protected]
   • 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.

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?
