Error running wear default device not found - android

I've created an android application and am now getting an "Error running wear, default device not found" error message. I can't think of anything I have done or changed that has made this start.
I have closed Android studio and re opened it
I've invalidated the caches and restarted
I've run a lint check
Looked at this question Android Studio cannot find default activity
Still no joy however.
My manifest is below
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.james.testing">
<uses-feature android:name="android.hardware.type.watch" />

Try changing the theme to something basic for now and see if it works.

Can't find launch activity

I removed these 2 lines from my android manifest file. Then I found them in internet and paste it to manifest file. And now my app can't find them. When I run my app says that there is no launcher activity and that may be I want to launch default activity.What can I do?
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.amadey.myapplication3" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</intent-filter>
</activity>
<activity
android:name=".HomeScreen">
</activity>
</application>
</manifest>

You have a doubly-nested intent-filter element in your manifest:
<intent-filter>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</intent-filter>
It needs to look like this:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Because an intent filter was surrounded with another intent filter, just like this:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

My app icon does not appear in the emulator home screen

I want specific ordered reasons why my app icon does not appear, I can run it on the emulator yet and I need to know what's wrong with my app? I'm a beginner my code is so simple, though I can't find why is this happening.
Here is my manifest:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".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=".MyActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="com.example.hp.app2.MyActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>

Instead of
<category android:name="android.intent.category.launcher" />
it must be
<category android:name="android.intent.category.LAUNCHER" />

This is a copy of my AndroidManifest.xml
Any help as to why the launcher is not being recognized? I tried running the code without applying DEFAULT to any other activity but it's still not working.
enter code here
<application
<activity
android:name="project.shirsho.Menu"
android:label="#string/app_name" >
<intent-filter>
<action android:name="project.shirsho.MENU" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="project.shirsho.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.Textplay"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.TEXTPLAY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>

You need to specify the MAIN and LAUNCHER in the the intent filter for the activity you want to start on launch by :
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
if you want that Splach Activity as your launcher , your manifest must be :
<application>
<activity
android:name="project.shirsho.Menu"
android:label="#string/app_name" >
</activity>
<activity
android:name="project.shirsho.MainActivity"
android:label="#string/app_name" >
</activity>
<activity
android:name="project.shirsho.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="project.shirsho.Textplay"
android:label="#string/app_name" >
</activity>
</application>

I believe that you are trying to make "project.shirsho.Menu" as the launcher activity, then it should be like:
<activity
android:name="project.shirsho.Menu"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
change,
<intent-filter>
<action android:name="project.shirsho.MENU" />
to
<intent-filter>
<action android:name="android.intent.action.MAIN" />
Hope this helps! :)

This is how your application part should look like. If you use eclipse to develop in it will help you create this (androidManifest.xml)
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<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=".SplashActivity"
android:label="#string/app_name" >
<intent-filter>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Help on Tab Layout example

New bee to Android, I need help on creating tabs.
I am following the example stated in http://developer.android.com/resources/tutorials/views/hello-tabwidget.html
When I run the application, I am not seeing any tabs but only Songs tab.
I am not able to figure out how to resolve this.
Below code is added under AndriodManifest.xml
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".HelloTabWidget"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
</activity>
<activity android:name=".AlbumsActivity">
<intent-filter>
<action android:name="com.example.TabWidget.AlbumsActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name=".ArtistsActivity">
<intent-filter>
<action android:name="com.example.TabWidget.AlbumsActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name=".SongsActivity">
<intent-filter>
<action android:name="com.example.TabWidget.AlbumsActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>

Make it look something like this:
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".HelloTabWidget"
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>
<activity android:name=".AlbumsActivity"/>
<activity android:name=".ArtistsActivity"/>
<activity android:name=".SongsActivity"/>
</application>
This part:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
is for the entry part of your app.

here is a very simple example for tab-layout:
Andorid Tab-Layout with icons

Android app icon shows on device to allow uninstall but does not allow to execute

I am able to run an android app in two virtual devices when degugging.(Galaxy tab and phone). When I close the app in debug mode the icon is not showing in the virtual device.
The same thing occurs when I load a signed .apk file to the actual devices.
The app icon shows when I go into manage applications. I can uninstall the app. Thats all I can do. I cannot launch the app since the icon is not visible with the other app icons.
I am using platform 2.2 with google api's 8.
What am I doing wrong? How can I get the app icon to show with other apps and be able to launch?
Here is my manifest file.
Any help is appreciated.

You should only be using <category android:name="android.intent.category.LAUNCHER" /> for one of your activities, not all of them. Try removing all others except the one that goes with <action android:name="android.intent.action.Main" />
EDIT: I may be wrong but I think you'll also need to capitalize MAIN as in <action android:name="android.intent.action.MAIN" /> for it to be recognised as the 'main' entry point (main activity).

Try to remove "android.intent.category.LAUNCHER" for each activity because android project must have only one LAUNCHER activity.

try to this if your main activity use this
<intent-filter>
<action android:name="android.intent.action.Main" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Other activity you can use this
<intent-filter>
<action android:name="android.intent.action.(your action )" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
I think it can be helpful to you .
