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>

how to add an activity to the android manifest

How do I add:
<activity
android:name=".MainActivity2"
android:label="#string/title_activity_main">
</activity>
into the AndroidManifest.xml
which currently looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bac"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="19" />
<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" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I'm fairly new to android programming and have yet to figure out a lot of stuff about transferring between pages and other things like that. Thanks for any help you give!

Just Add another Activity tag under your application tag
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bac"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="19" />
<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" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity2"
android:label="#string/title_activity_main">
</activity>
</application>
</manifest>
If you are new to android and trying to understand about manifest
Have a look at ANDROID-DEVELOPERS-SITE ..... Click here
Have a look at youtube-tutorial too hope this helps
It has all the information you need to get started knowing more about the manifest file

You need to add your Activity inside Application tag.
The activity is the child node of the application node. The multiple activities can specify by multiple nodes of activity.
Read this : manifest-intro
your manifest will be look like
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bac"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="19" />
<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" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Add your activities here -->
<activity
android:name=".MainActivity2"
android:label="#string/title_activity_main">
</activity>
</application>
</manifest>

you can add any number of activity inside your application tag in AndroidManifest.xml.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bac"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="19" />
<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" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- activity goes here-->
<activity
android:name=".MainActivity2"
android:label="#string/title_activity_main">
</activity>
</application>
</manifest>

to add an activity to the Manifest , just copy the content of the exesting activity in the manifest and remove the intent filter like this
---the original
<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>
</activity>
---the new
<activity
android:name=".yourNewActivityName"
android:label="#string/app_name" >
</activity>
you need add this in the application tag.
you need to change the android:name property to your new activity's name

Android || Error parsing XML, not well formed || Manifest.xml file

I am having trouble finding why my syntax is wrong in the manfest.xml file. It is probably something simple so it would be appreciated it you guys helped real quick. I must be missing a key syntax issue, as I have tried to fiddle with it and got nowhere so far. I had these xml files working earlier but randomly they deleted themselves.

You are missing a ">" in all your activity declarations after the first one.

One of the activity tags is written wrongly as <Activity>, thats why you were facing the error. It should be <activity>

How to prevent "MainActivity screen "display

I have an Android app in which the first screen is a menu display. Before it gets to the menu display though it displays a page with the launcher icon and "Main Activity" at the top. How do I prevent this display? Manifest file has this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.menu"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
--- edit
So the class that displayed the menu was called MainActivity.java. Maybe not a good idea, if only because it is not a good practice. So I renamed it to MenuActivity.java and changed the manifest accordingly(below). But the behavior is still the same.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MenuActivity"
android:label="#string/menu_activity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

What I'm understanding is that you don't want the ActionBar to appear at all in your MenuActivity. Since your target API is 11, you can add android:theme="#android:style/Theme.Holo.NoActionBar" to the Activity Declaration.
<activity
android:name=".MenuActivity"
android:label="#string/menu_activity"
android:theme="#android:style/Theme.Holo.NoActionBar" >

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.menu"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".YourCustomActivity"
android:label="#string/custom_activity_title" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Android manifest.xml problems

Following this: http://developer.android.com/training/basics/firstapp/starting-activity.html I am confused when editing the Android Manifest.xml file. It says that the file should contain this:
<application ... >
<activity android:name="com.example.myapp.DisplayMessageActivity" />
...
</application>
My android manifest.xml looks like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.nick.myfirstapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="4"
android:targetSdkVersion="15" />
<application android:label="#string/app_name">
<activity android:name="com.nick.myfirstapp.DisplayMessageActivity" />
...
</application>
</manifest>
and when I run the app everything goes fine except it says : "No Launcher activity found!
The launch will only sync the application package on the device!" Is this something missing from the android manifest.xml file?

declare Your Activity in AndroidManifest.xml as for Showing In Launcher as:
<application android:label="#string/app_name">
<activity android:name="com.nick.myfirstapp.DisplayMessageActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
see for more info how we set an activity which so in Launcher :
http://developer.android.com/reference/android/content/Intent.html
http://developer.android.com/reference/android/app/Activity.html

You need to change you manifest to the following. Doing this will tell Android that you want this Activity to be displayed in the Launcher using your icon.
<application android:label="#string/app_name" android:icon="drawable icon resource here">
<activity android:name="com.nick.myfirstapp.DisplayMessageActivity" android:label="Your Label">
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
In the docs the used ... to show that your normal code goes here. What you're doing is fine for non-launcher Activities.

You are missing the launcher intent and therefore the app finds no activity to launch at the start.
You need to lay out the activity like so:
<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>
</activity>

package="com.example.myfirstapp"
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.example.myfirstapp.DisplayMessageActivity"
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>
