Question

Try to build ionic project in android studio on Mac, error came up as follow, anyone can give some clue.

Element uses-feature#android.hardware.camera at AndroidManifest.xml:32:5-84 duplicated with element declared at AndroidManifest.xml:27:5-60

Removed the duplicate entry still not working.

AndroidManifest.xml File.

    <?xml version='1.0' encoding='utf-8'?>

New error:

Merging Errors: Error: Attribute meta-data#android.support.VERSION@value value=(26.0.0-alpha1) from AndroidManifest.xml:27:9-38 is also present at AndroidManifest.xml:24:9-31 value=(25.3.1). Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:25:5-27:41 to override. android main manifest (this file), line 26 

Answer 1

You have a duplicate <uses-feature android:name="android.hardware.camera" /> in your end of your xml file.

Remove any one permission of camera from Menifest file.

Answer 2

You have <uses-feature android:name="android.hardware.camera" /> and <uses-feature android:name="android.hardware.camera" android:required="true" /> . Remove the one not required.
