Question

每当我尝试启动动态壁纸的设置时，我都会遇到强制关闭问题。我真的没有任何东西，所以我不确定可能导致问题的原因......这是logCat

我认为这是权限拒绝行，但我不知道是什么原因导致它...我需要设置一些隐藏的权限吗？这是我的第一张liveWallpaper。

谢谢！

Answer 1

呃，我发现了问题......事实证明我需要清单中的首选项活动已将导出设置为“true”。有一个小时我永远不会回来！

Answer 2

虽然接受的答案肯定有效，但这不是正确的方法。将export设置为true只表示可以在应用程序外部启动活动。但是，应该这样做的方式是声明这样的活动：

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

Answer 3

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

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

<强>更新

参考：<uses-permission> element。
