"Error running second Activity: The activity must be exported or contain an intent-filter"

I can't seem to launch my application. It gives me an error like this: Error running second Activity: The activity must be exported or contain an intent-filter. Is there anything wrong with my manifest?
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.bill.myapplication1.MainActivity"
android:label="#string/app_name"
android:exported="true">>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.bill.myapplication1.SecondActivity"
android:label="#string/title_activity_second" >
</activity>
</application>

look there ,"android:exported="true">>", there is two ">"

change this in your manifest file
<activity
android:name="com.bill.myapplication1.MainActivity"
android:label="#string/app_name"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<activity
android:name="com.bill.myapplication1.MainActivity"
android:label="#string/app_name"
android:exported="true">>
You have double > near exported = "true"

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

android:allowBackup="true"
android:icon="#mipmap/ic_launcher"

show 2 apps when debugging in android

When I debug and install app in device, it's show 2 apps install in device (one open with Splashscreen & another open without Splashscreen ) . Guide me, what I'm doing wrong.
here is my manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.soft.prmk.alle"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:hardwareAccelerated="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

You have two Launcher Activities: MainActivity and SplashScreen. Remove one of those. Try this:
<?xml version="1.0" encoding="utf-8"?>
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:hardwareAccelerated="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".SplashScreen"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
</activity>
</application>

You have two LAUNCHER thats the issue
<category android:name="android.intent.category.LAUNCHER" />
Make it DEFAULT in MainActivity.
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

You have 2 launcher activities, remove intent-filter from one. I think SplashScreen should be launcher activity so remove from MainActivity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Android showing error while running

i have 2 activities AndroidSlite.java and SqLiteAdapter.java.. my manifest.xml file is given below.it shows No launcher activity found .while running
please help me with the code
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.cerebtec.androidsqlite"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<activity android:name="AndroidSQLite"></activity>
</application>
</manifest>

You have to enclose the intent filter around the launcher activity, in order to declare your launcher activity. E.g.
<activity android:name="AndroidSQLite"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
this way you are telling android that the launcher activity is AndroidSQLite

Use :
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Eclipse: Android: Can't Chance Launcher Activity

I just started an Android Project and i made a Splash.png and Splash Activity for my App, with the Splash.xml, and the Splash.java with the onCreate Method and the setContentView, I also change the Intent in the manifest so the Splash would be the LAUNCHER.
BUT the "MainActivity" is still default launcher, I cant change that.
And if I try to Clean up my proyect, Eclipse just wipes out everying I modified from the
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.learn.xandroix"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.learn.xandroix.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.learn.xandroix.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
This is what the Eclipse Console is showing:
[2013-07-22 11:28:56 - XAndroiX] Installing XAndroiX.apk...
[2013-07-22 11:29:06 - XAndroiX] Success!
[2013-07-22 11:29:07 - XAndroiX] Starting activity com.learn.xandroix.MainActivity on device S5830f33ed19b

Try this:
<?xml version="1.0" encoding="utf-8"?>
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.learn.xandroix.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.learn.xandroix.MainActivity">
</activity>
</application>
Cheers

Chnage this in you manifest.xml file
<activity
android:name="com.learn.xandroix.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="MainActivity">
</activity>

Consider this;
<activity
android:name="com.learn.xandroix.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.learn.xandroix.MainActivity"
android:label="#string/app_name" >
</activity>

Try this way:
Just care "action android:name" of 2nd activity.
Enjoy :)
<activity
android:name="com.learn.xandroix.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.learn.xandroix.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.learn.xandroix.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

no launcher activity found error

I created very simple activity that displays hello world and a button labled TEST, when i press this button the Toast will display a message and I run this app on the emulator.
the problem is that, when I try to run this app the console displays that
no launcher activity found
and nothing to be displayed on the emulator although the code has no error at all.
manifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.qr00"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
</activity>
</application>
Can anyone tell me how to solve the "no launcher activity found" error?

You need to add
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
So:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.qr00"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

You need to add this Intent in your Menifest file
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
</activity>

you can add this code in your manifest file in activity tag.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
</activity>
</application>

add like this
<activity
android:name=".YourclassName"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
