add support "MIUI BACKUP" magic header

[hexiaoyuan]

To support MIUI BACKUP magic header simple,
I do my patch like below,

--- a/src/org/nick/abe/AndroidBackup.java
+++ b/src/org/nick/abe/AndroidBackup.java
@@ -63,6 +63,25 @@ public class AndroidBackup {
             if (DEBUG) {
                 System.err.println("Magic: " + magic);
             }
+
+            if (magic.equals("MIUI BACKUP")) {
+                System.err.println("-- 1: " + magic);
+                String line2 = readHeaderLine(rawInStream);
+                System.err.println("-- 2: " + line2);
+                String line3 = readHeaderLine(rawInStream);
+                System.err.println("-- 3: " + new String(line3.getBytes("iso8859-1"), "UTF-8"));
+                String line4 = readHeaderLine(rawInStream);
+                System.err.println("-- 4: " + line4);
+                String line5 = readHeaderLine(rawInStream);
+                System.err.println("-- 5: " + line5);
+
+                magic = readHeaderLine(rawInStream);
+            }
+            if (!magic.equals("ANDROID BACKUP")) {
+                System.err.println("Invlaid Magic: " + magic);
+                throw new IllegalArgumentException("Invalid Magic " + magic);
+            }
+
             String versionStr = readHeaderLine(rawInStream); // 2
             if (DEBUG) {
                 System.err.println("Version: " + versionStr);

wish you enjoy it.
