Flutter : PlatformException(no_available_camera, No cameras available for taking pictures., null, null)

Question

guys! I am facing this camera version. It happened after I merged my projects. It says there is no camera available but back then it was running fine. Please have a look!

Please have a look at this error message and help in this. I am looking to hearing from you all. Thank you in advance.

Answer 1

If your compileSdkVersion and targetSdkVersion is 30 (or above), then add the queries info to your Android manifest file, directly under the manifest tag:

<manifest package="your.app.package.name">
    <queries>
          <intent>
               <action android:name="android.media.action.IMAGE_CAPTURE" />
          </intent>
    </queries>
</manifest>

That should resolve your issue.

Answer 2

I'm not sure adding QUERY_ALL_PACKAGES is the correct solution given the goal is to access the camera only. If targetSdkVersion=30 (or higher), adding <queries> to your AndroidManifest.xml looks to be a preferable solution as per here - https://stackoverflow.com/a/63246789/268156

<manifest package="com.example">
    <queries>
        <intent>
            <action android:name="android.media.action.IMAGE_CAPTURE" />
        </intent>
    </queries>
    ...
</manifest>

Answer 3

I face same issue. For android, you need to add Camera permission and Query all packages permission in AndroidManifest.xml file as below:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>

Answer 4

If you are targeting android 11/ android sdk 30 or above, you need to add the following permission to android manifest xml file.

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>

It may throw another warning, but you can just ignore it for the time being. Regards.
