签名生成的APK与Android Studio内部的签名不同

Question

I have generated an APK using Android Studio and I don't know why the APK behavior is different from installing the software using the usb wire on debug mode. I have two activities in the same application and when I install it from debug, it appears the first of them but if I install it using the APK, it is launched directly in the second activity.

Any hint?

Thanks!

EDIT: this is the new manifest after modifying it accordingly to the answer given by Bala Raja. However, the problem is that now Android is not identifying the second activity as a Launcher. What could I do?

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.test"
          android:versionCode="1"
          android:versionName="1.0">

                <category android:name="android.intent.category.LAUNCHER"/>
                <category android:name="android.intent.category.HOME" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>
</manifest>

Answer 1

<intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

paste this in your activity in manifest file which you want first.
