How to create update.zip?

How to create update.zip

 (full pure build)

 (correct update files)
 (edit /META-INF/com/google/android/updater-script)
 $ zip -r ../update-mira.zip *
 $ cd ../Auto-sign
 $ java -jar signapk.jar testkey.x509.pem testkey.pk8 ../update-mira.zip ../update-mira_signed.zip

I'm afraid, XXX custom rom and patches cross update same binary. What's happen?

Sink require framework.apk.

[Solved?] 2013/08/15 - One Problem!!

app install error

 $ adb root
 //$ adb remount
 $ adb shell mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system    
 $ adb push Mira4U.apk /system/app
 $ adb logcat
  I/PackageManager(452): /system/app/Mira4U.apk changed; collecting certs
  W/PackageManager(452): Signature mismatch for shared user : SharedUserSetting{416908d8 android.uid.system/1000}
  E/PackageManager(452): Package com.example.mira4u has no signatures that match those in shared user android.uid.system; ignoring!

Mira4U.apk couldn't install!!!! This app uses HDCP skip toggle, it's important!!

no relation to result in signed or unsigned

$ java -jar signapk.jar platform.x509.pem platform.pk8 Mira4U.apk Mira4U_signed.apk

android.uid.system

Mira4U.apk require android:sharedUserId="android.uid.system" for system db read/write. very easy way to sharing values in Java app and native layer.

-Java App
  SystemProperties.set(key, chk ? "1" : "0");

-native layer
  mDiabledLog = property_get("persist.sys.wfd.disablelog", val, NULL) && strcmp("1", val) == 0;

hmmmmmmmm

My Solution

read app xml directory from native layer!

  FILE* fp = fopen("/data/data/com.example.mira4u/shared_prefs/prefs.xml", "r");

other problem for Mira4U.apk
