Android Question Camera Permission issue with Android Ver 13 SDK 33

[GeoffT660]

I'm trying to get the camera functionality to work on a new Tera P166 device with integrated scanner but the camera won't open and reports an error

java.lang.SecurityException: com.bizmoblid was not granted this permission: android.permission.WRITE_SETTINGS.

. if I follow Erel's example from post https://www.b4x.com/android/forum/threads/permission-write_settings.94311/ I get the setting screen and can toggle to On but then I get this error

ava.lang.IllegalArgumentException: You cannot keep your settings in the secure settings.

when running the code

camera.OpenCamera(id)

in CamEx2. I've never had any issue accessing the camera on any other of the many devices that run my application. Please let me know if there is a solution for this issue. Thanks!

Try the following manifest code:

AddManifestText(<uses-permission android:name="android.permission.WRITE_SETTINGS" />)
AddActivityText(Main,
<activity android:name=".permission.WriteSettingsPermissionActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
)

Thanks Alex! This now gives me an error while compiling.

Linking resources    Error
AndroidManifest.xml:101: error: unexpected element <activity> found in <manifest><application><activity>.

This old app has not been converted to B4x pages.

Why do you need this permission? Do they provide Java documentation?

 

[GeoffT660]

I think I need this permission because the Error message says I need this permission when I call

camera.OpenCamera(id)

in the OpenCamera function of CamEx2. The error also occurs in the Camera2 example. Works on the previous version of the Tera P166 device running Android 9 but not on the new device running Android 13. Should I check with the manufacturer for this Java documentation? The full error message is:

Error occurred on line: 61 (CamEx2)

If I try your suggestion in this post: https://www.b4x.com/android/forum/threads/permission-write_settings.94311/ I get the Modify System Settings screen

and can toggle the setting to On but then the error message changes to:

Not sure what else I can do to make the camera work on this device.

 

[Erel]

Strange.

Should I check with the manufacturer for this Java documentation?

Yes.


Also try to use MediaChooser. It doesn't require any permission.
