Android Studio Debugger Errors of Packaged Mobile Game

Hello Everyone,

Since wanted to start saving game information such as coin,point,last selected character, my game wasn’t launched on android device after packaging. I started doing build settings and android setup again and struggled too much but nothing is changed. Then i used android studio debugger to see what is the main problem.

There are something but i couldn’t understand and i don’t know what to do about it on unreal engine with blueprints.

Here is the some error lines from manifest:

<application (Consider adding the attribute android:fullBackupContent to specify an @xml resource which configures which files to backup.)

    android:label="@ref/0x7f09000c"   (unknown resource type ref)
    android:icon="@ref/0x7f05001a"     (unknown resource type ref)
    android:name="com.epicgames.ue4.GameApplication" (Class referenced in the manifest, com.epicgames.ue4.GameApplication, was not found in the project or the libraries)

.

    <activity
        android:theme="@ref/0x0103000a"   (unknown resource type ref)
        android:label="@ref/0x7f09000c"       (unknown resource type ref)
        android:name="com.epicgames.ue4.GameActivity" (Class referenced in the manifest, com.epicgames.ue4.GameActivity, was not found in the project or the libraries)

        android:debuggable="false"
        android:launchMode="2" (Cannot resolve symbol '2')
        android:screenOrientation="7" (Cannot resolve symbol '7')
        android:configChanges="0x1fb3" (Cannot resolve flag)
     .

Is there any way to solve it from unreal engine? Or what should i do?

Thank you.
