I am new to Android, creating an Android application that have animations that will be displayed on the main screen (as in desktop) and I am planning to use sprites for this. But I don't know how to display the animation in the desktop. Please suggest if there is any better method. I am planning to create a train that runs around the desktop.Can any one help?
I think that you want to run activity with Transparent background.The following code is used to be a current window with Transparent background.In manifest file,
<activity
android:name=".First"
android:theme="#style/Theme.Transparent" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
If you want to floating that window :
<activity
android:name="Second"
android:theme="#style/Theme.Transparent.Floating" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Actually this is used for show two activities in one screen in my example...

I noticed that
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
This part above can make icons.
So, This code will create two icons after installing one apk. But those launch different activity each-A_Activity or B_Activity
<activity
android:name=".ui.A_Activity"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".ui.B_Activity"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
But anyway, this acts like one app after launching one of them. After launching A_Activity, it can reach the other Activities or Resources that B_Activity moves to or uses if the implementation is the similar or the same.
However, what I want to know is making two different names for each icon. Mine has two icons but the same name. Is there any way to give different app names for them? Because I wanna test two different modes at the same time after installing it.
The text underneath the icon on the HOME screen is taken from the
android:label="..."
attribute of the <activity> description in the manifest. If you don't provide this, it uses the android:label of the <application>.
So all you need to do is to provide different android:label strings for each <activity> in the manifest.
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.
Hoping someone can point out my failure here. Ive developed a custom launcher app which I want to replace the home screen. I also want the activity accessible via a custom URL "myapp://launcher.android.com."
I'd love to explain why, but to cut a long story short, the Android Gods demanded that I consolidate two activities (each working fine) into a single Activity.
Can someone check over my manifest file to point out any errors or fields I need to fix? Or even a superior alternative?
<activity
android:name=".KioskLauncher"
android:label="#string/app_name"
android:theme="#android:style/Theme.DeviceDefault.NoActionBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
<intent-filter>
<data android:scheme="myapp" android:host="kiosk.androiddev.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
You need an extra attribute to be added to the activity tag.
Try adding this to the activity tag:
android:launchMode="singleTask"
I made two apps, each one has classes that I want to use as shortcuts or independent apps (equally fine with me). They worked fine in Android 4.0.3, but not in 4.1+.
The fist app is called xvf, and has a class FolderList (named Fima) that I want to make into a shortcut. The other app is ave that has a class ViewMap (named Ave Map) that I want as a shortcut too. However, I have two problems:
1) I cannot add the shortcut to the home screen in 4.1+. I find the shortcut inside "Widgets", but when I release the shortcut in the home screen, instead of placing the icon, the class is executed as if it was clicked, and it is not added.
2) Fima appears as an independent app in Android 4.4 and not as a shortcut, so I was able to add it, but appears as a widget in Android 4.1.2... Why Fima appears as an independent app???
This is the relevant part of both manifests:
xvf:
<activity
android:name=".FolderList"
android:label="Fima"
android:icon="#drawable/fima_launcher_128"
android:theme="#style/MyThemeNonFS" >
<intent-filter>
<action android:name="android.intent.action.CREATE_SHORTCUT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
ave Manifest:
<activity
android:name=".ViewMap"
android:label="Ave Map"
android:icon="#drawable/guara_128"
android:configChanges="orientation|screenSize"
android:launchMode="singleTask"
android:theme="#style/MyThemeNonFS" >
<intent-filter>
<action android:name="android.intent.action.CREATE_SHORTCUT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/comma-separated-values" />
<data android:mimeType="text/csv" />
</intent-filter>
</activity>
What am I doing wrong? How do I make the shortcuts to work properly, or how do I make the classes to look as independent apps?
Thanks!!

The only solution I found to this problem was to add
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
to the two activities. Now the second activity appears as an independent app, but at least now the icon stays in the HOME screen when released.
in my app, there is two activity and i want to make activity1 to the starting activity after installation.
But now the RUN button (is showed right after packgae installing) is disabled.
below is the manifest file. thanks.
<activity ...1>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity ...2>
<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.ACTION_POWER_CONNECTED" />
<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED" />
</intent-filter>
</activity>
android) can i set a default activity that runs right after installing
No activity "runs right after installing". The user has to launch it from the launcher.
below is the manifest file
No, it is not. That is not even valid XML.
Also, note that your third <intent-filter> is invalid. Not only are you missing any category (you need at least DEFAULT for activities), but ACTION_POWER_CONNECTED and ACTION_POWER_DISCONNECTED are not activity actions.
I am going to take a guess that you really mean to ask: "I have two activities, both described as ACTION_MAIN/CATEGORY_LAUNCHER, and now the Run button does not work -- what can I do?" The answer would be "either remove the ACTION_MAIN/CATEGORY_LAUNCHER <intent-filter> from one of them, or mark one of the two as disabled (android:enabled="false") and enable it later on using PackageManager."
I think the problem is the second:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
You shouldn't have 2 activities flagged as the MAIN and LAUNCHER activity.
Try removing it within activity2.
Check out: http://developer.android.com/reference/android/content/Intent.html the intentfilter s are discussed.
