1, first in unity to make a good subcontracting, the method of subcontracting as shown
Ready to pack and pack the Android installation package (Apk+obb), for example: abc.apk + Abc.obb
2. Install the APK to the Android device first, then rename the corresponding Obb file to:
Main.<bundle Version code>.< Package name >.obb
and copied to the Android device under the "/android/obb/< Package name >/" path.
As in Unity3d editing, you can see the "bundle Version Code" and the package name (i.e. "bundle Identifier") at the location of the project setup.
Take the above ABC example (assuming its "bundle Version Code" value is 2, the package is named "com." Demo.abc "):
-First, install abc.apk;-on Android device then, rename Abc.obb to "Main.2.com.demo.abc.obb";
-then copy the file "Main.2.com.demo.abc.obb" to the "/android/obb/com. demo.abc/" Path of your Android device;
-Launch the app and you'll find that the newly installed app is ready to work.
It's so simple.
