Android: Camera Preview Orientation on HTC EVO (Android 2.1 or 2.2)

由 六眼飞鱼酱① 提交于 2019-12-08 18:40:29
I am developing an Android application that relies on the camera API, using an HTC EVO as my testing device. No matter what I've tried so far, the only time the camera preview looks right is in landscape mode (90 degrees rotation, to be specific). It seems as though there is no way to orient the preview correctly when in portrait mode (0 degrees rotation). The default camera application on the device (for HTC Sense) allows for any kind of rotation without any problem, so I know that there is no hardware limitation. I even downloaded some source code from HTC's developer site , but it's all in

Showing Live Wallpaper in a 1.6 target app by detecting if it's a 2.1 device?

由 六月ゝ 毕业季﹏ 提交于 2019-12-07 19:28:25
问题 We're building an Android app with target SDK 1.6, so it will run on 1.6 devices and higher. We'd like to support Live Wallpapers, which we know is 2.1+ only. Is there a way to build one app with 1.6 SDK as the target, but detect if the device it's running on is 2.1, and only in that scenario call the live wallpaper API. We're trying to avoid having to build a separate 1.6 and 2.1 versions, and would like to be able to support Live Wallpapers for only 2.1 devices. So to be clear- 1 app, that
