Android异常：Caused by: java.lang.SecurityException: Neither user 10044 nor current process has android.permission.WAKE_LOCK.

原因：未授权使用唤醒锁。

解决：在AndroidManifest.xml的<manifest>标签中加入：

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

顺便授权写SDCard：

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