Followed this tutorial.
FROM TUTPLUS
Tut seems very simple and logical, the annoying part is, it just don't work(although everything seems to make sense).
when i click the home button my app wont run, neither i get any option to select among the default launcher app and my app, i can see the app among launcher app when i go to settings>home.
I did provide filters as given in tutorial.
<activity
android:name=".HomeActivity"
android:label="Bawa launcher"
android:theme="#style/apptheme"
android:launchMode="singleTask"
android:stateNotNeeded="true"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Though a bit late, may help others. In phone's settings, selecting the default launcher to your launcher will solve the problem. In my case, above code worked by this method.
Everything is perfect in your code. All you need to do is remove:
<category android:name="android.intent.category.LAUNCHER" />

I am writing an Android App that has one main activity and one subactivity. When I install the app on my phone to test it out, I get two icons instead of one. The first icon is for the main activity and the second is for the subactivity. I don't want/need an icon for the subactivity.
Does anyone know how to turn this off in my app code, so that only the icon for the main activity is installed? Any information you can provide is greatly appreciated!
Thanks,

Does your application manifest list an intent filter under your sub-activity that matches the main launcher?
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Make sure that your sub-activity is not filtering for these intents.
Edit: Just to be very clear, make sure the above lines are not listed under your sub-activity. That intent filter lets the Android system know that you intend for it to be listed as an entry point to your application.
We have the same problem but i fixed it this way
before my code below in manifest
<application
android:debuggable="true"
android:allowBackup="true">
<activity android:name=".SplashActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.noupdate.apptest_noupdate.MainActivity"
android:icon="#drawable/ic_launcher"
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>
Notice that in the SplashActivity inside the intent is this code
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
i only deleted the category
<category android:name="android.intent.category.LAUNCHER" />
So after i deleted the intent-filter category in splash it didn't install two app icon but only one for main the code will be like this notice that the intent-filter category is deleted
<application
android:debuggable="true"
android:allowBackup="true">
<activity android:name=".SplashActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
<activity
android:name="com.noupdate.apptest_noupdate.MainActivity"
android:icon="#drawable/ic_launcher"
android:theme="#android:style/Theme.NoTitleBar"
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>
it really helps
It creates two App icon because you must have added the given filter to two of your activities. See manifest.
<category android:name="android.intent.category.MAIN" />
Remove the above statement from the other one. Then you are good to go.
Like in the other answers,
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER"/>
Was the culprit. However, in my manifest I only had one activity with that intent filter. As it turns out, I am using a library I built and it has an activity declared in it's manifest which uses that intent filter. So, in short, be sure your app's manifest and dependencies, if any, only have one activity with the intent filter.
I guess that in your AndroidManifest.xml, you've got both activities having the LAUNCHER intent-filter. Remove it from the second activity, and you should be set!
You have
<intent-filter . . . >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
along with
android:icon="#drawable/icon.png"
set for both activities.
What that means is that this is a launcher icon, put me on the home screen. Only set those for the activit(ies/y) you want on the home screen.
I was searching answer to exactly the same question. It appears the only thing needed (in addition to recommendations on removing MAIN and LAUNCHER intent filter) is to rebuild your project - that will clean things up and upon next launch I saw single icon on my device (just running application on device after changes did not help).
if anyone run into this issue using Pebble SDK. I noticed PebbleKit Androidmanifest.xml holds a LAUNCHER activity as well. This is what caused it for me. Just remove this part. It will not effect Pebble functionality.
SIMPLE answer..
REMOVE:
<category android:name="android.intent.category.LAUNCHER" />
From your AndroidManifest.xml
Leave your intent-filter alone.
<intent-filter android:icon=”drawable resource” android:priority=”Integer” /intent-filter>
Priorities are set for the parent component. This setting may help you to set the parent icon for your Android app development.
My application works as a launcher. But, I guess I did something wrong by making it a launcher. For instance, the user selects my application as Default Launcher (clicks 'Always'). However, when the user exits from the application, it appears again, because it's the default launcher. How can I fix it?
<activity
android:name="com.comeks.cocuktablet.Main"
android:label="#string/app_name"
android:launchMode="singleInstance"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
The code comes from my manifest. I also want to make MAIN activity launcher.
Edit:
I realized my exact error. I also wrote a code to start my app on boot. The problem is that when I close my device and open it again, I cannot exit from it.
Thank you for your all answers. I solved my problem by calling Android's home launcher while exiting from app.
Just remove
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
from intent-filter
Each manufacturer makes a custom build of Android. Is this modification done in source or is it in app ?
If its in source : pointers to appropriate links would be useful.
It's called a launcher, which is a normal APK application. It's a normal Activity which reacts to a certain Intent.
You can create another one, and install it on your phone. When you press the home button it will ask which Launcher to use.
<activity
android:label="#string/app_name"
android:name=".ClassNameOfYourLauncher">
<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.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
I think you're talking about the Launcher. That's the first thing which comes to my mind. Its a System apk which will be there in app folder in system directory. If you need to modify that, you better create a new launcher of your own. Here is a link on how to go about doing that.
I have the following code in my Manifest:
<activity android:name="com.fletech.android.apparent.CategoriesGrid"
android:configChanges="keyboardHidden|orientation">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
When I run the app in Eclipse it starts this activity in the emulator, as expected.
But when I also add:
<action android:name="com.fletech.android.apparent.action.APPARENT_MAIN" />
right below the other action, and run the app, it only installs it to the emulator but doesn't run it. Why?
What I wanted to achieve is this: I would like to be able to show a dialog to the user (from another apps) to chose between all my apps that have "com.fletech.android.apparent.action.APPARENT_MAIN" as an action.
If you want to specify another launch scenario, you should just add another whole intent-filter block rather than putting all of the action clauses in the same one.
I am writing an Android App that has one main activity and one subactivity. When I install the app on my phone to test it out, I get two icons instead of one. The first icon is for the main activity and the second is for the subactivity. I don't want/need an icon for the subactivity.
Does anyone know how to turn this off in my app code, so that only the icon for the main activity is installed? Any information you can provide is greatly appreciated!

Does your application manifest list an intent filter under your sub-activity that matches the main launcher?
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

Make sure that your sub-activity is not filtering for these intents.
