"No Launcher activity " found error in eclipse while running android app - android

I have wrote a simple code in eclipse.when I tried to run it from emulator I got a message:"Unfortunatlly App is stopped"..And logcat message is "No launcher activity found"..
This is my Android-Manifest.xml file..
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.prolific.pl2303hxdsimpletest"
android:versionCode="11"
android:versionName="2.0.2.11" >

android:targetSdkVersion="15" />

android:label="#string/title_activity_pl2303_hxdsimple_test"
android:screenOrientation="landscape"
android:launchMode="singleTop"
android:theme="#style/AppTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
<!-- action android:name="android.hardware.usb.action.USB_DEVICE_DETACHED" /> -->
</intent-filter>
<meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
android:resource="#xml/device_filter" />
</activity>
</application>
</manifest>
I don't know why this error is coming..Anyone have idea why this error is coming??
Thank you,
Laxmi


Try to change activity name to
android:name=".PL2303HXDSimpleTest"
Also, it is a good practice to end the name of the activity with Activity suffix, i.e. MailActivity or MyActivity.


Try to remove this line:
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
Reason:
Multiple action tags in a single intent-filter tag will cause the error.

Service in binded Jar doesn't come up without "RECEIVE_BOOT_COMPLETED"

I have an App that uses a Service that I've added by a Bindable Jar.
Current state:
this Jar has an own Manifest (see below), when I don't touch anything on this Manifest everything works as it should.
Problem:
This Jar lets on Deployment to Device always its launer AppIcon on Device.
So my App leaves finaly two launcher icons, the one desired and the other from the Jar.
My Approach was to delete follow Part from Manifest:
android:theme="#style/AppTheme">
<activity
android:name=".ScanDemoActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Doing this the App Crashed on BootUp with Error: BootReceiver not found ...
Deleting the next few Lines:
<receiver android:name="com.company.scandemo.BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<category android:name="android.intent.category.HOME"/>
</intent-filter>
</receiver>
caused started correctly on bootUp, but the Service didn't come up on BOOT_COMPLETED, when I start the App via Launcher icon everything worked.
Wished Behaviour:
I want the Main App to leave only one launch Icon and startup correctly on Boot
Here is the Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Widget : No Launcher activity found

I already see the questions about "No Launcher activity found!".
I developped a widget which worked well and suddenly I have this error.
I have a configure activity declared with an intent filter APPWIDGET_CONFIGURE.
Here is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="tina.prime"
android:versionCode="5"
android:versionName="1.3.2">

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name">
<receiver android:name="tina.prime.TheWidget">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/config" />
</receiver>
<service android:name="tina.prime.UpdateWidgetService"></service>
<activity android:name=".ConfigureActivity">
<intent-filter>
<action android:name="android.app.action.APPWIDGET_CONFIGURE" />
</intent-filter>
</activity>
</application>
</manifest>

The error tells you everything: No Launcher activity found
This means that you haven't declared any activity in your manifest as a launcher, in order to fix this, pick the activity you want to use for starting the app, and add the following attribute to it:
<category android:name="android.intent.category.LAUNCHER" />

AndroidManifest.xml The markup in the document following the root element must be well formed

I have got Eclipse to generate a Basic android Hello World app, But it has 2 errors: first, in my AndroidManifest.xml on these two lines:
I get The markup in the document following the root element must be well formed, Also My R.java Will not generate, no matter how many times I clean my project. Any Answers?

Thanks, Jonathan

Here is your manifest,
You should not specify more than one Manifest and You should not specify more than one <application> tags.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</manifest>

It may be that you are missing something, but sometimes doing a simple re-format of code: CTRL+SHIFT+F, clears the problem.

I looked at your manifest file. The error is caused because you have 2 declarations of <manifest /> tag.
It begins with:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.jfkingsley.maclogin"
android:versionCode="1"
android:versionName="1.0" >
Then some comments follow and another declaration starts:
<!--
Declare the contents of this Android application. The namespace
attribute brings in the Android platform namespace, and the package
supplies a unique name for the application. When writing your
own application, the package name must be changed from "com.example.*"
to come from a domain that you own or have control over.
-->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.jfkingsley.maclogin" >
<uses-permission android:name="android.permission.CALL_PHONE" />
Your either forgot to comment one of the manifests tag, confused something, or following a wrong tutorial. The AndroidManifest file should have only one <manifest /> tag

The Auto-generated AndroidManifest.xml file has some problem by itself. There is two manifest tag and two uses-sdk tag inside it. That is the problem. Do as follows:
1- Delete the closing tag of first manifest tag which is:
</manifest>
2- Delete definition tag of the second manifest tag which is:
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="net.learn2develop.fragments"
android:versionCode="1"
android:versionName="1.0" >
3- If there is two uses-sdk tag, also delete the second uses-sdk tag.

I added a new activity to my app, and it gave this error after. The manifest disappeared from android-studio completely.
I had to edit the manifest with a text editor. It seems that when I added a new activity, Android Studio created a new tag then added the new activity tag inside in the manifest file, rather than just adding the tag with the new activity in the manifest.
After you update the manifest, the project worked fine.

<?xml version="1.0" encoding="utf-8"?>
< xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.groofy">

android:allowBackup="true"

/> should not be at the end of the file I had the same issue the error means the xml file is not correctly formatted you should try removing the / in front of the > or simply reformat

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>

Android StackWidget unable to bind

I am currently trying to add a widget to my application and have been basing my implementation on this code http://developer.android.com/resources/samples/StackWidget/index.html
I have put all my stack widget related classes in their own package within my main package.
When I try to add the widget it is unable to bind and hence the cards are not displayed (it just states the default text "This is the empty view")
Below is my manifest.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</receiver>
<service android:name="stackwidget.StackWidgetService"

</application>
</manifest>
Error message:
E/RemoteViewsAdapterServiceConnection(474): bind(): Unknown component ComponentInfo{com.bencallis.dealpad/com.bencallis.dealpad.stackwidget.StackWidgetService}
I am sure there is a simple mistake somewhere which is making the component info repeat com.bencallis.dealpad.
Any ideas?

It turned out it was to do with my manifest and a problem locating the service. I was missing a . in the name (which gives it the path).
Silly mistake!
