maheshmnj · 2019-12-31T11:46:54Z

I am trying to use image_picker^0.6.1+11 to capture images from camera as the source it works fine for the first time but when I try to retake the image the app crashes with a log lost connection to the device without any exception or error.
UseCase: I want to capture three images from camera and view them in an imageview.
I have tested the app on the latest flutter master and stable channels but has same issue here's my flutter doctor -v output

Hi @maheshmnj
Try to use the latest version of image_picker and camera.
Are you still experiencing with this issue?
Thank you

maheshmnj · 2020-01-01T03:34:38Z

thanks for that info I tried it on an android as well as ios device,it works without a problem with the latest version of the image picker. 0.6.2+3

akshaybenk · 2020-01-01T10:43:17Z

This issue still persists in
image_picker: ^0.6.2+1.
The image_picker crashes and the app goes back to the previous screen.
I tried it on redmi 6A and realme 3 pro android devices.

This is frustrating as it is an important feature for an app.

Can you try with v0.6.2+3 I tried it, it seems to work pretty well on Android, Also I have tested on Redmi 6a and I saw it seemed to loose connection sometimes but when I ran a release version of the app it worked without any problem, I could click images multiple times and it worked well.

akshaybenk · 2020-01-02T06:14:13Z

Hey @maheshmnj,
Thank you for your kind response.
The problem I am facing is, I have checked with 0.6.2+3 on the test devices(mi4w and miA2 and iPhone 6s).
Everything is working perfectly on these devices.
Even the previous versions of the plugin were working perfectly on the test devices.
When I checked with client devices, I found it was crashing for 0.6.2+1.

If I release an update for the app with the latest version of the plugin, I am not sure how will it work on redmi6a and realme 3 pro. Because these were the client's device running the release apk.It would be a huge problem if it fails to work as releasing frequent updates becomes frustrating for clients to keep on updating the app.

I checked 0.6.2+3 on 1gb ram device (to see if low ram is the issue), it worked smoothly.

try{ var image = await ImagePicker.pickImage( imageQuality: 90, source: ImageSource.camera, ); debugPrint('Image size : ${image.lengthSync()}'); imageFiles.add(image); setState(() {}); } catch(e){ debugPrint('image-picker-error ${e.toString()}'); }

The above code stores clicked images in a list.
Please correct me if the code is wrong.

Hey,

I am having the same issue on Android, after I click the tick on Camera to accept the picture, the App crashes with no errors

Device:
Google Pixel 3a

OS Version:
Android 10

Plugin version:
image_picker: ^0.6.2+3
camera: ^0.5.7+2

Code:
var image = await ImagePicker.pickImage( imageQuality: 90, source: ImageSource.camera, );

maheshmnj · 2020-01-07T17:13:40Z

I am using the latest image picker plugin it works well .is there any specific reason to use the camera plugin?if not, Can you try removing the camera plugin from pubspec.yaml

OliverNarramore · 2020-01-08T07:48:38Z

Using Flutter version 1.12.13+hotfix.5, i'm also experiencing issues with the image_picker package.

On Android, if I use the gallery as a source and select an image it works fine. If I use gallery as the source, but select the back button on my device, the app crashes with no logs.

Furthermore, If I use the camera as the source, I can capture and recapture images, but when I select "OK" to confirm the image, the app, again, crashes with no logs.

I'm using the latest image_picker and camera plugin versions.

I have also tried removing the camera plugin from pubspec.yaml, but the behaviour is exactly the same with or without it.

This also crashes on an emulator.

maheshmnj · 2020-01-25T04:16:24Z

I dont know whats wrong for you but this works well for me on emulator as well as real device on ios and android heres the working demo

Whenever I use camera as the source for image picker on Android Q, the device immediately loses connection with no explanation or errors. I can see the camera, take the image but when confirming the image nothing happens. If i select the "X", my app restarts because it had initially crashed opening the camera. This only happens on android. When testing this on a simulator, I get an error stating "Camera Error Can't connect to the camera"

I have attempted flutter pub cache repair, as well as using "flutter clean" multiple times. Does anyone have any suggestions?

Still losing connection and app restarts every time, not even sometimes.

Min SDK: 21
Target SDK: 29
image_picker: ^0.6.3+1

I've tested in Mi A3, Nokia 6.1 Plus and Motorola E5. Works perfectly in those.

chiragmittal19 · 2020-03-02T05:32:33Z

Still waiting for a solution. This is a severe crash and I've no idea what's going wrong in this particular Xiaomi device.

OliverNarramore · 2020-03-02T07:14:14Z

Also occurring still on a One Plus device. Fine on Samsung S10. Wondering if there’s something different for specific device brands.

hfranco346 · 2020-03-04T04:29:38Z

I am facing this problem now, when i run the app on a virtual device it works fine, but when i run it into my xiaomi device it stop debbugin in vscode and pop to the main activity, i need help

I also have the same problem. Detaching device when opening image picker.
Device: Google pixel 3
image_picker: ^0.6.4

rajtri · 2020-04-02T06:54:58Z

this issue is in debug mode only, if you build the app in release mode, it works perfectly fine.

maheshmnj · 2020-04-02T13:48:24Z

This issue still persists in
image_picker: ^0.6.2+1.

Can you try with 0.6.2+3 I tried it, it seems to work pretty well for Android,Also I have tested on redmi 6a and I saw it seemed to loose connection sometimes but when I ran a release version of the app it worked without any problems I could click images multiple times and it worked well

yes Everyone who is facing this issue please try the release version of the app,for me the debug verison works well too

phanbaohuy96 · 2021-07-20T08:58:41Z

Hi, any solution to this problem yet? I get a lot of reports of problems selecting images from the camera. Also, Crashlytics can't log where the crash is coming from.

kari538 · 2021-07-20T11:35:10Z

Use a different package. :( It's the only solution.

Werisu · 2021-07-21T19:56:43Z

I tried putting a <uses-permission android:name="android.permission.CAMERA"> but it didn't work

maheshmnj · 2021-07-23T12:40:13Z

Is this issue still valid with the latest image_picker: ^0.8.2 ?, I could not reproduce it on k20 Pro, Incase if anyone wants to try here is the sample code with the updated API. https://gist.github.com/maheshmnj/666de97c013a804b8b343966fca0941c

(Note: No configuration is required for Android for image_picker ^0.8.1 and above, meaning you can just add the plugin and try the sample code )

Hello everyone! After countless fails with "lost connection with device" while trying to pick an image from gallery, I found a plugin which met my demands: "photo_manager" plugin, alone, or used also here: https://pub.dev/packages/wechat_assets_picker

Although it does not directly load the gallery and you pick from it and it goes back to the app, in this case the plugin loads the images of your device as assets, and you can access any image from any folder, and you can choose how to display those images, like a grid view "emulating" your gallery.

I hope it helps you as it helped me! :D

Device: Xiaomi A2 lite (Android One device)

Step to reproduce: Image picker pick multiple image then app crashed (losing connection with device)
image_picker version: 0.8.3+2

Using the image_picker with image_cropper sorted the issue for me. I can't really explain it, but it did sort it for me.

@OlaleyeJumoke Can you try to explain?

carman247 · 2021-10-20T13:43:55Z

Can't find a way to fix this in my app. Will have to use the camera plugin for now, which is a shame.

agiletechie · 2021-11-10T18:22:07Z

Still crashes and shows blank screen sometimes. Works fine on emulator though.
Using latest image_picker: ^0.8.4+4

mothattack · 2021-11-11T01:01:55Z

almost 2 years and many updates later, and this is still broken on a physical android device. I'm over it

oodavid · 2021-11-12T09:07:13Z

@Abhijithsp we've had very similar reports. Our solution has been to bundle different camera modules into the app and let the user try different plugins via a settings screen. It's been needlessly troublesome - especially since the camera package forces 16:9 aspect ratio - #80393 #15953 and #45665. Essentially, we're letting our users choose between image_picker (unstable and correct images) or camera (more stable, but incorrect images)

stuartmorgan · 2021-11-17T19:48:40Z

This is not something that can be fixed in the plugin; it is not technically a bug, although I understand the frustration with the effect it has on the experience. The reason that there aren't any logs or crash reports is that the app isn't crashing, it's being terminated by the OS to free memory, because while the image picker activity is active the Flutter application is technically a background app, and thus subject to collection by the OS when there is memory pressure.

For end users, the solution is to implement state restoration in your application, and to use these instructions from the plugin README to get the results of the image picker activity during restoration.
For the flutter run workflow, I don't see a solution other than re-attaching to the restored application on completion.

The only way to avoid this would be to implement a custom, in-application image picker experience from scratch. That's out of scope of this plugin—but is something that interested members of the community could certainly build.

(The reason this is specific to Android is that on iOS the system model is extremely different; instead of providing a standard set of activities for operations like these, the OS provides components that are displayed within the application, so the application that's doing the image selection is in the foreground the entire time. If at some point Android provides a similar component, image_picker could switch to that to resolve this.)

Given that this is, within the constrains of the way Android activities work, not something we can change, I'm going to close this. #93807 tracks improving the README to make this more clear.

oodavid · 2021-11-19T09:17:48Z

@stuartmorgan - this is a most excellent insight! Thank you

Do you have any articles we can read about how Android chooses which apps to terminate in the background? ie: does it select those using the most memory? If so, it may mean that we may have an undetected memory leak.

stuartmorgan · 2021-11-19T15:50:00Z

Do you have any articles we can read about how Android chooses which apps to terminate in the background? ie: does it select those using the most memory?

Android documentation discusses it at a very high level, but there is (likely by design) not a clearly described set of rules; it's up to the OS to decide when to terminate processes, and which ones.

Given that how recently used the process was is called out as one factor that's likely to be considered, it could very well be the case that on some devices the image picker is using so much memory that all other non-essential processes are killed.
