My AndroidManifest.xml as below
<activity
android:name="com.holidaynumbers.MainActivity"
android:label="#string/app_name"
android:configChanges="orientation|screenSize|keyboardHidden"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="allplayer" />
</intent-filter>
</activity>
Tried many different ways to run application with launcher but not able to run it and can't see app icon in apps

try to separate intent filter:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="allplayer" />
</intent-filter>

Changing default activity in android

hello I want to change default activity. But when I do that the app doesn't launch at all without any errors
<activity
android:name="com.example.dimmer.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="com.example.dimmer.DevicesActivity" >
</activity>
This way MainActivty launches with no proble. It also goes to Device activity when I press the button. So everything works fine.
Now I need DevcieACtivty to be default one.
I change Manifest like that
<activity
android:name="com.example.dimmer.DevicesActivity"
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.example.dimmer.MainActivity" >
</activity>
but now app doesn't launch. no errors. nothing is written in console.
it's just doesn't do anything,
what might be a problem?
It starts to write the following error
ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.dimmer/.MainActivity }

Since you've defined your package as "com.example.dimmer", you can remove package name and use just the name of Activity with dot in front:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".DevicesActivity"
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>
</application>
Moreover, check your Run configuration settings in Eclipse. If your launching activity was set to MainActivity, and in manifest you make DevicesActivity as main, your app might not start when launching via Eclipse. Click arrow for RUN icon and choose "Run Configurations",
Then make sure you choose DevicesActivity as Launch:

Uninstall the app on your phone, and redownload it.

Make sure you implement setContentView in onCreate method.
In other way try clean the project Project > Clean and run it.

I am not sure but Now you can some step a head.
such as
1. delete Android.R (in above in your activity )
2. or replace package.R for example , com.example.name.R
3. check you res folder or sub-folder resources .
such as layout attribute right or not.
4. Delete gen and bin folder.
5. clean your project thus: project=>clean
6. restart your eclipse.
Remember that if your resource not found then show this type error.
Best of luck!

Click arrow for RUN icon and choose "Run Configurations"
Android Application =>select project
open Target tab
select Always prompt to divice
click run and select Divice online

I'm making an android app and after editing it I encounter this problem. It has no errors but it doesn't launch either. Is my problem with my manifest or launch activity?
Updated Manifest:
<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.bpi.gears.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="com.bpi.gears.home"
android:label="#string/title_activity_home" >
</activity>
<activity
android:name="com.bpi.gears.profile"
android:label="#string/title_activity_profile" >
</activity>
</application>
</manifest>
I still can't run my app.

You have the same activity defined twice. remove this and try:
<activity
android:name="com.bpi.gears.MainActivity"
android:label="#string/app_name" >
</activity>
You have this in your manifest:
<action android:name="android.intent.action.main" />
It needs to be like this:
<action android:name="android.intent.action.MAIN" />
you have main instead of MAIN

My app isn't appearing in my app drawer even though it has installed

Why won't the app appear in the app drawer? It says in the App Manager that it is installed but I can't seem to open the actual app as it isn't in the app drawer. It doesn't automatically open it up once it's installed either.
Here is what is said when I choose to run on my phone (which is on Jellybean). It says the same thing when I install it to an emulator.

Here's the android manifest.

<action android:name="android.intent.action.RESULTS" />

</intent-filter>
</activity>
</application>
</manifest>
Anything I'm doing wrong?
SIDENOTE I also get errors saying that I do not need permission for the activities categorised as 'DEFAULT'. Could this be to do with it? I need it for the startActivity() in one of my clases so is it really not required?

I'm assuming that introduction is your first Activity. You need to add another action to it, like in the following code:
<activity
android:name=".Introduction"
android:label="#string/title_activity_introduction" >
<intent-filter>
<action android:name="android.intent.action.INTRO" />
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

I know it is solved question, but this solution did not work for me and I wanted to share my solution here.
I was trying to add deep link support to my app, And in the documentation the
<intent-filter android:label="#string/filter_view_http_gizmos">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="gizmosexample"/>
</intent-filter>
I added those intent filters to my launcher activity and after app drawer stopped showing the app icon in the launcher.
So if #RaghavSood's solution above did not work, try to remove those filters or any other custom filters from the launcher activity's filters.

Android App not running on any device

I'm having trouble running ANY app on both an emulator and a device. Just running the simple "Hello World" app is not working. The app gets installed on the emulator but never executes. I can find it when I go Menu -> Manage Apps but the only thing I can do from there is uninstall it. It seems there is a setting that is not forcing it to run automatically.
Also, something that was weird was my computer would never let me install the new updates. It would just say "Downloading ....." but nothing ever happened. I fixed the problem by going into Safe Mode with Networking but I can still not run any app. Any ideas???
Here is what it says when I go to Run as -> Android App

Thanks.

You've to change your main activity's <intent-filter> tag filter in AndroidManifest.xml file.
<application android:name="......"
android:icon="#drawable/app_icon"
android:label="#string/app_name" >
<activity android:name=".yourActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Means, you've to change your activity's <action> and <category>
Edit
Just change like below in your manifest file. It will launch your application.
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="parent" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
