In order to be able to take pictures or record videos, you may need additional
permissions depending on the Android version and where you want to save them.
Read more about it in the
official documentation.

WRITE_EXTERNAL_STORAGE is not included in the plugin starting with version
1.4.0.

If you want to record videos with audio, add this permission to your
AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.yourpackage">
<uses-permission android:name="android.permission.RECORD_AUDIO" />

<!-- Other declarations -->
</manifest>
copied to clipboard
You may also want to save location of your pictures in exif metadata. In this
case, add below permissions:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.yourpackage">
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<!-- Other declarations -->
</manifest>

⚠️ Overriding Android dependencies
Some of the dependencies used by CamerAwesome can be overriden if you have a
conflict. Change these variables to define which version you want to use:
buildscript {
ext.kotlin_version = '1.7.10'
ext {
// You can override these variables
compileSdkVersion = 33
minSdkVersion = 24 // 21 minimum
playServicesLocationVersion = "20.0.0"
exifInterfaceVersion = "1.3.4"
}
// ...
}

Only change these variables if you are sure of what you are doing.
For example, setting the Play Services Location version might help you when you
have conflicts with other plugins. The below line shows an example of these
conflicts:
java.lang.IncompatibleClassChangeError: Found interface com.google.android.gms.location.ActivityRecognitionClient, but class was expected
