Low Memory error on Android 10 #74

wimZ · 2020-05-13T12:49:02Z

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.

I have observed the same issue on my side

ChrisTomAlx · 2020-07-20T16:44:32Z

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.

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.

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.

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

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

wimZ · 2020-09-20T19:22:08Z

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

ChrisTomAlx · 2020-09-21T08:08:55Z

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

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 · 2020-11-10T12:20:51Z

Released a new beta version of the plugin.

To test it :-

Make sure to remove the old version using cordova plugin rm cordova-plugin-document-scanner
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 :)

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 · 2020-11-17T09:23:51Z

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 · 2020-11-17T12:32:14Z

@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,

On first try it works! I’ll do some more testing later Thanks

benediktcarda · 2020-11-17T20:57:48Z

After adding

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

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 · 2020-11-17T21:11:50Z

@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,

hi @ChrisTomAlx ..

i saw in your scan library

createdirectory when opencamera is not working with API 29

even if i put androidx and this one still not working also
<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application"> <application android:usesCleartextTraffic="true" android:requestLegacyExternalStorage="true"/> </edit-config>

and this code one is not working anymore with API 29 ,
Environment.getExternalStorageDirectory()

i did debug , and i found this :

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 #82 (comment)

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

Saúde e tenha um bom dia :)

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 · 2022-03-13T15:38:20Z

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 · 2022-06-29T06:48:49Z

@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 ;)
