Why does my Android app need autofocus?

The Android app needs the following permissions:

Screen layouts: SMALL NORMAL LARGE XLARGE
Required device features
    android.hardware.camera
    android.hardware.location.network
    android.hardware.wifi
    android.hardware.location
    android.hardware.location.gps
    android.hardware.camera.autofocus
    android.hardware.touchscreen

I am using the camera, but why does it need autofocus too? How can I disable it? The Android SDK doucmentation says that

<uses-feature android:name="android.hardware.camera.autofocus" />

lines are in the AndroidManifest.xml which declare this requried features, but there is nothing like this in mine.

  • If the camera didn't autofocus, how could it produce a focused image?

    The android.permission.CAMERA implies android.hardware.camera and android.hardware.camera.autofocus. See Android docs

    Try adding 

    <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />

    to your tiapp.xml or custom AndroidManifest.xml. Adding this may also require you to use SDK tooling higher than API 7.

    • You can put the uses-feature statements in TiApp.xml under the Android | Manifest section:

          <android xmlns:android="http://schemas.android.com/apk/res/android">
        <manifest android:versionCode="14" android:versionName="2.03">
            <uses-feature android:name="android.hardware.camera.autofocus" android:required="false"/>
        </manifest>
    </android>

      I had the same problem as the OP, and this solved it.
