so, I have a little problem, while opening my app.
I have an "ugly" popup opening for 1-2 sec and then my app goes in.
How exactly can I open my app directly without that 2 sec empty page?
btw - I changed the string of the android:name of my launcher activity to verify that it is this exact activity that is opening empty, and the name changed in the actionbar so it is this activity.
the picture of the first and "ugly" screen
<---
here's my manifest code :
<application
android:name=".BaseApplication"
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.Holo.Light.NoActionBar" >
<activity
android:name=".UI.activity.HomeActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustResize"
android:launchMode='singleTask'
android:theme="#style/Theme.MyAppTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
anyone had this kind of problem before?
thanks a lot.
if anyone ever experience this kind of issue like me,
the solution for me was changing the theme of the app to
android:theme="#android:style/Theme.Holo.Light.NoActionBar"
thank you Kesh for relating that question!

This is my first time asking a question on on here, but I have found the answer to innumerable questions I've had before on here. However, I just can't make this one work. I'm simply trying to write an app to replace the homescreen. Here is what I am trying, and I can't see what I'm missing.
To keep it as simple as possible, I reduced it to just this testing application. The only thing I changed after starting a new project was the manifest.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hometesting"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<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=".HomeActivity"
android:theme="#style/AppTheme"
android:launchMode="singleTop"
android:stateNotNeeded="true" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME"/>
<category android:name="android.intent.categoty.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
I have tried it both in the emulator and my own phone, in the latter, it doesn't show up in the chooser. I can select it as the default home application in the user settings, but when i hit the home button, it just brings up the chooser without my app as an option. The pre-installed home screens and one other app that I downloaded show up as options, but my app doesn't. In the emulator, a click on the home button just brings up the default homescreen.
I have tried it with and without the separate launcher activity, and with and without the LAUNCHER intent. I have tried installing, uninstalling, restarting, and every permutation thereof.
All I want is for the home button to lead back to an activity that I wrote. Any help would be greatly appreciated.
Update: I also tried it on a generic cheap Chinese device, and still nothing.
Can anyone tell me how to change the app name? My app is taking splash as the app name on the Emulator since my first activity is splash.
EDIT:
It takes "splash" as the app name before the app is launched. Once it is launched the right name is displayed.
Manifest:
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.sanginfo.temperatureconvertor.SplashActivity"
android:label="#string/title_activity_splash" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.sanginfo.temperatureconvertor.LoginActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.LoginActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
In your manifest file under application tag change this tag with whatever you want as a app name..android:label="#string/app_name"
use the name attribute on application node as describe in :
http://developer.android.com/guide/topics/manifest/application-element.html
#stylojack_10
Go to the File name String.xml (Project->res->values->string.xml)
change the value of the tag name app_name.
you can even make your own tag there and make change in Android Manifest file under tag find android:label="#string/"your custom app name""
Hope this will resolve your problem
Solution 1: (this solution works most of the time)
Go to res -> values -> strings.xml -> appname, change name of the app there.
No go to Android Manifest and check if it looks like this:
<application
android:label="#string/app_name"
.......................
>
If android:label="#string/app_name" is changed to android:label="MyApp", than change it to one shown above. Your problem should be solved.
Solution 2:
there was a file called OldAppName.launch
it is located in workspace/.metadata/.plugins/org.eclipse.debug.core/.launches
also stuff on:
/User/workspace/.metadata/.plugins/org.eclipse.ltk.core.refactoring/.refactorings
also a glitch in Eclipse to show old app name instead of changing the name.
I am in trouble, I want to start my application from starting every time but it's not being.
When I exit from my application & come again. I found same activity which I have left before exit.
Now If I **shut down or switch off** my Android Device direct when my application is in foreground & then I **switch on device again**. I get same activity which I have left earlier. But I want to fresh application from login page. Because my setter & getter is null after switch on device, and I found all value null in my application.
My Manifest file is below:
<activity
android:name=".Main"
android:launchMode="singleTop"
android:screenOrientation="portrait"
android:theme="#android:style/Theme.Dialog" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".screens.ScreenSplash"
android:screenOrientation="portrait" />
<activity android:name=".screens.LoginActivity" />
<activity
android:name=".screens.LoginActivity"
android:configChanges="orientation|keyboardHidden" />
<activity
android:name=".screens.MainMenu"
android:configChanges="orientation|keyboardHidden" />
Kindly help me which is the problem & what should I do. Any help would be appreciated.
Add to your activity manifest
android:clearTaskOnLaunch="true"
According to your Manifest .Main is the launcher activity. so when your application is launched from icon tap then this is the first activity to display and rather if your application is not having any other activity on top of the stack.
so if you want to see the fresh login activity then make the login activity as launcher activity.
Maybe you want to try setting launchMode to standard?

I'm having a problem with my app after changing the default activity in the manifest. This is the manifest after i changed it. As far as i can see it's syntactically correct.
<application android:icon="#drawable/icon" android:label="#string/app_name">
<uses-library android:name="com.google.android.maps" />
<activity android:name=".loginActivity"
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="CouncilPlannerActivity"></activity>
<activity android:name="MainTabActivity"></activity>
<activity android:name="MapTabActivity" android:theme="#android:style/Theme.NoTitleBar"></activity>
<activity android:name="NodeFormActivity"></activity>
<activity android:name="viewNewsActivity"></activity>
</application>
The problem is when i deploy the app to my device it works fine first time. However, when i close the app with the home button it refuses to open again. Clicking the icon in the devices app list doesn't do anything.
If i change the default activity to the one it was at originally it works fine. Is this a bug or is there another reference to a default activity that i'm missing?
I'm developing on Android 2.2 if that makes a difference.
I just noticed the logcat spits out an error when i try to open the app : "Permission Denied: checkComponentPermission() reqUID10064"
You probably need to post the loginActivity in question here so we can see if there are any problems in the activity. Otherwise double check that the loginActivity is in the same package as the other activities, if its not you need to change the ".loginActivity" part of the manifest to its relative location to the main package, aka "somename.loginActivity"
I think the problem is in loginActivity class. May be you check for already loggined user and finish activity in this case?
my android application crashes and shows force close when i tilt the mobile phone. is there any suggestions that i can remove such problem? By the way i am developing a LBS application which uses the google maps (MapView).
I have a splash screen and then shown a ListActivity as below :
<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=".Home" android:label="#string/app_name" android:configChanges="orientation" android:windowSoftInputMode="stateHidden">
<intent-filter>
<action android:name="com.nepways.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
what is wrong with my declaration, the splash screen loads and list activity is also whown correctly but when i change the orientation the application is closed. Please help me.
When you change your orientation the activity is restarted
look at the logcat to see what exception causes your application to FC
You can change your manifest to disable activity restarting by customizing configChanges, if you stil have the problem override onConfigurationChanged() to fix what is generating this exception (like initialize something that may cause a nullpointer)
First of all as it is said the app is restarting (or as it is said in reference redrawing) each time when you change orientation.
To block it in your manifest file in activity you have to put this line which describes the activity orientation:
<activity android:name=".Splash"
android:label="#string/app_name"
android:screenOrientation="portrait">...
And about this buttons, or keymaps. Telling the truth Ive got thise warnings sometimes but it doesnt change anything in my app. So first change the orientation settings and then it should work correct.
If you want use other screen orientation remember to check here:
http://developer.android.com/guide/topics/manifest/activity-element.html
If you want to avoid restarting your activity on orientation change, you can put this in the activity in the manifest file:
android:configChanges="orientation"
Otherwise, we will need to see more code, and a stacktrace.
