Try to change capital letters to lowcase in your package name.

change default start activity error

This is my code
<?xml version="1.0" encoding="utf-8"?>
<!-- To auto-complete the email text field in the login form with the user's emails -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".RegisterActivity"/>
<activity
android:name=".SplashActivity"
android:exported="true" />
<activity
android:name=".LoginActivity"/>
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" />
</application>
At the beginning, my project exported property is in the LoginActivity section.
But after I change exported="true" to SplashActivity it's not work...
I tried to change to RegisterActivity section and got the same error.
Event log is "Error running app: The activity must be exported or contain an intent-filter"
my android studio version is 2.3.3 and project min SDK is 19
Is there anyone have the same problem?..
Updare:
This is my latest code

But I got the
same problem
...

try defining your Splash activity like this :
<activity
android:name=".SplashActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

In the Manifest file you must have an Activity that is set as Main so the app will know what to launch first.
By adding the following intent-filters you set the following Activity as main.
<activity
android:name=".Activity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

When inserting code in AndroidManifest.xml, my app stops

My Manifest runs like this;
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
>
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
But deleting android:theme="#android:style/Theme.NoTitleBar" in activity, it works. It's about one month that I am struggling with this in Eclipse. Any advice will be welcomed.

AndroidManifest.xml - The element must be a direct child of the <application> element error

I made a copy of one of my working projects for another project. Ever since I can't get the AndroidManifest.xml to work properly. I get the error The element must be a direct child of the <application> element or The element type "manifest" must be terminated by the matching end-tag "</manifest>"error. I have refactored everything else and don't see any errors in my classes. Just the xml file is being a pain. What is wrong with this file? It looks fine and looks like my working one. Eclipse seems to think there are errors.

You have directly close your application tag
Replace this :
<application
android:allowBackup="true"
android:hardwareAccelerated="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" />
by this :
<application
android:allowBackup="true"
android:hardwareAccelerated="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
EDIT :
You have to replace this :
<activity
android:name="com.mydomain.qsd.MainActivity"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait"/>
by this :
<activity
android:name="com.mydomain.qsd.MainActivity"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait" >
This :
<activity
android:name="com.mydomain.qsd.SplashScreen"
android:screenOrientation="portrait" />
by this :
<activity
android:name="com.mydomain.qsd.SplashScreen"
android:screenOrientation="portrait" >
This :
<receiver
android:name="com.mydomain.qsd.gcm.GCMReceiver"
android:permission="com.google.android.c2dm.permission.SEND" />
by this:
<receiver
android:name="com.mydomain.qsd.gcm.GCMReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
And finally this :
<activity
android:name="com.mydomain.qsd.NotifyActivity"
android:screenOrientation="portrait"
android:label="#string/title_activity_notify" />
</activity>
by this :
<activity
android:name="com.mydomain.qsd.NotifyActivity"
android:screenOrientation="portrait"
android:label="#string/title_activity_notify" />

Your application Tag and also Activity tags have self close so remove that
<application
android:allowBackup="true"
android:hardwareAccelerated="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" /> <----- remove /
