I see. Thanks for the explanation! So if I don't declare it, based on the table, it will assume I uses features:
android.hardware.camera and android.hardware.camera.autofocus So in order for me to show the app in Android Market that does not support camera (like low end camera-less tablets), I will need: <uses-feature android:name="android.hardware.camera" android:required="false" /> I am not too sure whether I need to declare or not? Since autofocus is often unnecessary for many apps. <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" /> On 11月26日, 下午8时45分, Mark Murphy <[email protected]> wrote: > 1) delivers the same results as 3) due to a side-effect of requiring > that permission. > > http://developer.android.com/guide/topics/manifest/uses-feature-eleme... > > "Some feature constants listed in the tables above were made available > to applications after the corresponding API; for example, the > android.hardware.bluetooth feature was added in Android 2.2 (API level > 8), but the bluetooth API that it refers to was added in Android 2.0 > (API level 5).
