+ * Support routines to send messages to the Android in-kernel log buffer,
+ * which can later be accessed through the 'logcat' utility.
+ *
+ * Each log message must have
+ *   - a priority
+ *   - a log tag
+ *   - some text
+ *
+ * The tag normally corresponds to the component that emits the log message,
+ * and should be reasonably small.
+ *
+ * Log message text may be truncated to less than an implementation-specific
+ * limit (e.g. 1023 characters max).
+ *
+ * Note that a newline character ("\n") will be appended automatically to your
+ * log message, if not already there. It is not possible to send several messages
+ * and have them appear on a single line in logcat.
+ *
+ * PLEASE USE LOGS WITH MODERATION:
+ *
+ *  - Sending log messages eats CPU and slow down your application and the
+ *    system.
+ *
+ *  - The circular log buffer is pretty small (<64KB), sending many messages
+ *    might push off other important log messages from the rest of the system.
+ *
+ *  - In release builds, only send log messages to account for exceptional
+ *    conditions.

- *   platform release 1.5
- *
- *   Third-party source AND binary code relies on the definitions

- *
- *   - DO NOT MODIFY ENUMS (EXCEPT IF YOU ADD NEW 32-BIT VALUES)

-/*
- * Support routines to send messages to the Android in-kernel log buffer,
- * which can later be accessed through the 'logcat' utility.
- *
- * Each log message must have
- *   - a priority
- *   - a log tag
- *   - some text
- *
- * The tag normally corresponds to the component that emits the log message,
- * and should be reasonably small.
- *
- * Log message text may be truncated to less than an implementation-specific
- * limit (e.g. 1023 characters max).
- *
- * Note that a newline character ("\n") will be appended automatically to your
- * log message, if not already there. It is not possible to send several messages
- * and have them appear on a single line in logcat.
- *
- * PLEASE USE LOGS WITH MODERATION:
- *
- *  - Sending log messages eats CPU and slow down your application and the
- *    system.
- *
- *  - The circular log buffer is pretty small (<64KB), sending many messages
- *    might push off other important log messages from the rest of the system.
- *
- *  - In release builds, only send log messages to account for exceptional
- *    conditions.
- *
- * NOTE: These functions MUST be implemented by /system/lib/liblog.so
