        android:targetSdkVersion="17" />

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"

You can't set two main activity as below:

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

this is wrong..

your Mainfist.xml should be like:

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" 
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

<activity android:name="LoginActivity"/>
