我认为这是权限拒绝行，但我不知道可能导致它的原因...我需要设置一些隐藏权限吗？这是我的第一个动态壁纸。

谢谢！

Answer 1

是的，您需要在 Android 清单文件中设置 SET_WALLPAPER 权限。您可以在 元素中使用以下行；

<uses-permission android:name="android.permission.SET_WALLPAPER" />

更新：

参考：< ;uses-permission> 元素。

Answer 2

呃，我发现了问题......事实证明我需要清单中的首选项活动已导出设置为“true”。还有一个小时我就回不来了！

Answer 3

虽然接受的答案肯定有效，但这不是正确的方法。将导出设置为 true 仅意味着可以在应用程序外部启动该活动。但是，应该这样做的方法是像这样声明活动：

    <activity android:name="com.example.SettingsActivity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
        </intent-filter>
    </activity>
