Cameraview: startPreview failed (applySizesAndStartPreview)

[ritesh94]

After I am done selecting photo from galley and return back to the same screen of cameraCapture
I get the following error :

E/CameraController: uncaughtException: Unexpected exception: java.lang.RuntimeException: startPreview failed

I get the same issue from my app's production users running android 6.0 (samsung & motorola devices) so far.

com.otaliastudios:cameraview:1.4.1

Does this happen with 1.4.0?

[ritesh94]

It happens with 'com.otaliastudios:cameraview:1.4.1'

[iftekhar-ahmed]

@natario1 I cannot confirm 1.4.0 is problematic as i used the 1.4.1 in production. However while development i think tried 1.4.0 without any problem. ITC I'd say the problem could well be in both versions. For your help, here are devices and android version details for problems reported so far in my app -

All problems in Android 6.0

Devices - Samsung Galaxy S5 & Galaxy A5, Motorola G Turbo Edition, Motorola G4 Play

[natario1]

I have no idea what could cause this. The only thing might be some things that were introduced in 1.4.1. I recommend going back to 1.4.0 and try for now, sorry. Let me know if you have more info.

[ritesh94]

ohk... Any idea when new version will be releasing with fixes ?

[chekashovsoftermii]

I have same problem.
Device: Xiaomi Redmi 3S.
OS: Android 6.0.1

[natario1]

@checkashovsoftermii does it happen with 1.4.0?

[chekashovsoftermii]

@natario1 Yes

[natario1]

Can you add steps to reproduce the issue?

[semihozkoroglu]

hello, i added my stacktrace from fabric crash report. @natario1 could you help me? lib version 1.4.1 and i updated latest version but there is no information latest version yet. This crash occured 1.4.1 version.

i used CameraView height 325dp. Maybe reason can be this?

Hello, I am still seeing this issue on 1.5.0. It only happens on my S8 and Note 8 devices. I did figure out a fix in case anyone is having the same problem as me.

Cause: The cameraView isn't completely destroyed when loading to a new fragment, in my case a photo preview fragment.

Fix: To fix this I put cameraView.destroy() in my method that loads the new fragment, running cameraView.stop() in just onPause() is not good enough. If you're using two activities instead of two fragments like in the demo, this probably wouldn't happen.

This is probably not intended but it works for now.

Hi, same issue with a Samsung Galaxy Tab S2

E/CameraController: uncaughtException: Unexpected exception: java.lang.RuntimeException: startPreview failed java.lang.RuntimeException: startPreview failed at android.hardware.Camera.startPreview(Native Method) at com.otaliastudios.cameraview.Camera1$12$2.onPictureTaken(Camera1.java:521) at android.hardware.Camera$EventHandler.handleMessage(Camera.java:1115) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.os.HandlerThread.run(HandlerThread.java:61)

[terlono]

Here's what i found. I downloaded the lib locally and attached it and after some mingling i discovered that if i put a catch on the exception generating lines:

try { mCamera.startPreview(); } catch (Exception e) { Log.e(TAG, e.getMessage()); }

Even if the exception happens the camera returns to normal. Also one thing, it happend only on devices which were using SurfaceTexture instead of SurfaceHolder. Probably something with setting the max height and width on the preview there.

[natario1]

@terlono thanks for investigating.

Are you sure it's not the opposite? I would expect that this happens with SurfaceHolder (device / app with no hardware acceleration), not with SurfaceTexture.

[natario1]

Can you reproduce this with the demo app? If so, can you post logs coming from it in a txt file? From start up to the moment it crashes.

[terlono]

Sure thing, but that will have to wait untill evening since im on a commute right now.

[natario1]

Thanks 👍 I'd be happy to fix this with your collaboration.

I have same error, library version 1.5.1, android version 6.0.1, device Galaxy s5

[k-farhan]

[the-dagger]

Same issue here with Galaxy Tab A 7.0, Android version 5.1.1, Lollipop.
Library version is 1.5.1.

[satishverma30]

Facing same issue, if fixed please let me know

[natario1]

With #265 you can now catch this exception in the error handler, instead of having the app crash.

I still think it would have been cool to understand if there is a bug in the library or not - and this will be more difficult with #265 because we'll get less reports. But we were not able to fix this so...

I will close this now. If you get this exception again (after #265 is merged), please open a new issue with CameraLogger logs so we can see if there's something wrong on our side.

[PriyaSindkar]

Still facing same issue with Moto G4 Plus, API-24. hardwardAccelerated is true and therefore app is using SurfaceCameraPreview.

Note: I have dual camera previews in my activity and facing this issue for one of them (whichever is started last)

[mayurpateltristate]

When i launch app i am facing this kind of exception
