How to make an APP that is universal for Android and IOS?
Android and IOS applications cannot be used universally, and there is no universal application. You can choose to develop an application for one system first, and then compile an application for another system through transplantation. Android uses an apk application, and IOS uses an ipa application. APK is the abbreviation of AndroidPackage, which is the Android installation package (apk). APK is a file format similar to SymbianSis or Sisx. You can install it by directly transferring the APK file to the Android emulator or Android phone for execution. The apk file is the same as sis. The project compiled by androidsdk is packaged into an installation program file in the format of apk. IPA is the abbreviation of Apple application file iPhoneApplication. To put it simply, the software under Mac is just like the green software under Windows. It can be used after decompression. No installation is required. To uninstall, just delete the program file (the pkg format installation package is not involved here).

1. Create an update directory that contains the content you want to upgrade or replace.
For example:
update/
update/system
update/system/app
update/system/app/doodle_jump.apk
update/META-INF
update/META-INF/com
update/META-INF/com/google
update/META-INF/com/google/android
update/ META-INF/com/google/android/update-script
This directory contains the doodle_jump game. After the upgrade, the apk will appear in the /system/app/ directory of the phone.
The META-INF directory contains the upgrade script. The content of the update-script script is as follows:
show_progress0.5000000
copy_dirPACKAGE: systemSYSTEM:
show_progress0.1000000
You can add corresponding commands according to your own upgrade content.
2. Create a compressed package
Run in the update/ directory:
$zip-qry../update.unsigned.zip./
The update.unsigned.zip compressed package will be generated in the parent directory of update/
3. Signature
$java-Xmx512m-jarsignapk.jar-wkey.x509. pemkey.pk8update.unsigned.zipupdate.zip
Generate a signed update.zip package, in which
signapk.jar, key.x509.pem, key.pk8 are related to the specific mobile phone System related
4. Put the signed update.zip package into the root directory of the mobile phone's sdcard,
restart the system to enter recovery mode, and select
applyupdate. zip, restart the phone after success
ok, now there is doodle_jump game on the phone, and it cannot be deleted~
