Attribute "name" was already specified for element "activity" - android

I am following the guide to set up a serial Bluetooth application from TutorialsPoint.
However, I was prompted an error from Android Studio and I am a newbie.
Errors are :
Error:Attribute "name" bound to namespace "http://schemas.android.com/apk/res/android" was already specified for element "activity".
Error:Cannot read packageName from /Users/ooiquanzee/AndroidStudioProjects/ECG/app/src/main/AndroidManifest.xml

</application>

You have defined .MainActivity twice remove one from them.
And also you have defined action and category name as qzname
please update it as follow:
<activity android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

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: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

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>

Error:Execution failed for task ':app:processDebugManifest'.?

i don't know why this error arises suddenly it came in my stackrace
Error:Execution failed for task ':app:processDebugManifest'.

Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:25:5-27:34 to override.

this is my manifest file, i had updated my android studio 2.3.2 recently.

There is a version conflict in with the support library you used and the support version defined in your merged manifest file. You should add <meta-data> tag in your manifest file as shown below in order to override the conflict.(This is clearly mentioned in suggestion along with error log, see it)
<?xml version="1.0" encoding="utf-8"?>

the Manifests have different SDK Versions and cannot be merged
you needed to edit Manifests.this may help you

use this below code or go back to the older version to continue your project.

android:allowBackup="true" error on "true"

I have one problem my code has android:allowBackup="true" error on "true"
<?xml version="1.0" encoding="utf-8"?>

</activity>
</application>
</manifest>
I used calculate distance project but there are many projects, when I create a project then error generate of in manifest file.
<application android:allowBackup="true">
Please tell me answer

That's because in some of your libraries, there's at least one that uses allowBackup set explicitly to false. You can use tools:replace in your manifest.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.dsadas.bottombardmo"
xmlns:tools="http://schemas.android.com/tools">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:replace="allowBackup">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

you have not specified a name for one of your activities in the androidmanifest.xml. Enter a name and you should be good.
