问题描述

我想创建自己的LiveWallpaperPhaperPrapiew，即向用户显示所选动态壁纸的全屏预览(没有"Set Wallpaper"和"设置"按钮)库存操作系统预览所具有).

从2.1重建LivePicker-class(http://android.git.kernel.org/?p=platform/packages/wallpapers/livepicker.git; = rere ;;f=src/com/Android/壁纸/LivePicker; H = 1557E0AE77AA8B0F8191472A204B5A7B4ADD31A4; HB = Master"rel ="nofollow noreferrer"nofollow noreferrer"android.git.kernel.org )工作很大，所以我能让用户选择一个壁纸预览，但实际的LiveWallPaperPrappiew-class尝试导入以下私有接口/类:

import android.service.wallpaper.IWallpaperConnection;
import android.service.wallpaper.IWallpaperService;
import android.service.wallpaper.IWallpaperEngine;
import android.service.wallpaper.WallpaperSettingsActivity;

是有没有办法在我的应用程序中显示LiveWallpaper而不诉诸使用私人API(我显然不想做)?

谢谢！

调查同样的问题，但也击中了一端.

我的想法是我不需要访问iwallpaperconnection等，但我可以在绑定服务上使用反射.

但是，我得到了 Warn/ActivityManager(96):权限拒绝:访问服务ComponentInfo {com.android.wallpaper/com.android.wallpaper.grass.grasswallpaper.grass.grasswallpaper}从pid = 4196，Uid = 10070需要android.permission.bind_wallpaper

查看壁纸所需的权限android.permission.bind_wallpaper，它是普通应用程序无法使用的系统许可.

编辑: 创建一个名为当前壁纸的应用，可在市场上提供 https://market.android.com/details?id=com.elsewhat .android.currentwallpaper

它基本上显示了独立应用中的当前壁纸，并允许您通过标准壁纸选择器的意图更改壁纸.

应用程序使用主题android:theme ="@ android:style/theme.wallpaper.notitlebar.fullscreen"

问题描述

I would like to create my own LiveWallpaperPreview, i.e. to show the user a fullscreen preview of what the selected Live Wallpaper looks like (without the "Set Wallpaper" and "Settings" button that the stock-OS preview has).

Rebuilding the LivePicker-Class from 2.1 (android.git.kernel.org) works great, so I am able to let the user select a wallpaper to be previewed, but the actual LiveWallpaperPreview-Class tries to import the following private Interfaces/Classes:

Is there any way to display a LiveWallpaper in my app without resorting to using the private APIs (which I obviously don't want to do)?

Thanks!

Looking into the same problem, but also hit a dead end.

My idea was that I didn't need access to IWallpaperConnection etc., but that I could use reflection on the bound service.

However, I get WARN/ActivityManager(96): Permission Denial: Accessing service ComponentInfo{com.android.wallpaper/com.android.wallpaper.grass.GrassWallpaper} from pid=4196, uid=10070 requires android.permission.BIND_WALLPAPER

The permission android.permission.BIND_WALLPAPER is required for viewing the wallpaper and it is a system permission not available to normal apps.

EDIT: Created an app called Current Wallpaper that is available on the market https://market.android.com/details?id=com.elsewhat.android.currentwallpaper

It basically displays the current wallpaper in a standalone app and allows you to change the wallpaper through an intent to the standard wallpaper picker.

The app uses the theme android:theme="@android:style/Theme.Wallpaper.NoTitleBar.Fullscreen"
