Eclipse: Android: Can't Chance Launcher Activity

Eclipse: Android: Can't Chance Launcher Activity - android

I just started an Android Project and i made a Splash.png and Splash Activity for my App, with the Splash.xml, and the Splash.java with the onCreate Method and the setContentView, I also change the Intent in the manifest so the Splash would be the LAUNCHER.
BUT the "MainActivity" is still default launcher, I cant change that.
And if I try to Clean up my proyect, Eclipse just wipes out everying I modified from the
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.learn.xandroix"
android:versionCode="1"
android:versionName="1.0" >
<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.learn.xandroix.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="com.learn.xandroix.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
This is what the Eclipse Console is showing:
[2013-07-22 11:28:56 - XAndroiX] Installing XAndroiX.apk...
[2013-07-22 11:29:06 - XAndroiX] Success!

Try this:
<?xml version="1.0" encoding="utf-8"?>
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.learn.xandroix.MainActivity">
</activity>
</application>
Cheers

Chnage this in you manifest.xml file
<activity
android:name="com.learn.xandroix.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="MainActivity">
</activity>

Consider this;
<activity
android:name="com.learn.xandroix.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="com.learn.xandroix.MainActivity"
android:label="#string/app_name" >
</activity>

Try this way:
Just care "action android:name" of 2nd activity.
Enjoy :)
<activity
android:name="com.learn.xandroix.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="com.learn.xandroix.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.learn.xandroix.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

show 2 apps when debugging in android

When I debug and install app in device, it's show 2 apps install in device (one open with Splashscreen & another open without Splashscreen ) . Guide me, what I'm doing wrong.
here is my manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.soft.prmk.alle"
android:versionCode="1"

android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

<activity

</application>
</manifest>

You have two Launcher Activities: MainActivity and SplashScreen. Remove one of those. Try this:
<?xml version="1.0" encoding="utf-8"?>
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:hardwareAccelerated="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".SplashScreen"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<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>

You have two LAUNCHER thats the issue
<category android:name="android.intent.category.LAUNCHER" />
Make it DEFAULT in MainActivity.
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

You have 2 launcher activities, remove intent-filter from one. I think SplashScreen should be launcher activity so remove from MainActivity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

No launcher in manifest?

I have 2 activity, I want to run one first. If I run this code, Console will write this: No Launcher activity found!, but i declared LAUNCHER in manifest?
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.manif"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<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="com.example.manif.MAIN" />
<category android:name="android.intent.category.LAUNCHER" /> //<--here is a problem, i think
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.example.manif.SECOND_CLASS" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>

Change the action name to :
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

try to replace this
<intent-filter>
<action android:name="com.example.manif.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
with this
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Don't use intent filter and other thing second time-
<activity
android:name=".MainActivity"
android:label="#string/app_name" />
This code is enough for second activity.

just remove tag:
<action android:name="com.example.manif.SECOND_CLASS" />

Android No Launcher activity found

I am having this problem.
I created a new xml layout (splash screen) and in manifest set it as Launcher category.
I did this before tons of time but it never happened before.
When MainActivity is LAUNCHER categpry and I run Spalsh Activity via intent it works.
Doing opposite I get error No launcher activity found.
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".SecondActivity"
android:label="Second Activity" >
<intent-filter>
<action android:name="net.learn2develop.SECONDACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<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>
</application>
No problem in this one, but if I modify it to
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".SecondActivity"
android:label="Second Activity" >
<intent-filter>
<action android:name="net.learn2develop.SECONDACTIVITY" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
I get error.

try with following
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".SecondActivity"
android:label="Second Activity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="net.learn2develop.SECONDACTIVITY" /> <!--(or android.intent.action.VIEW) -->
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>

try this:
<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

Change order of activity to open first

I am working on a project, where i have 4 activities. Each time i run the project, activityA opens first and then other activities, but i want that the MainActivity should open first and then other activities.
Where should i define the order of activities to open.
Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.it"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".ActivityA"
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 android:name=".GeneralAct" />
<activity android:name=".BackUp" />
<activity android:name=".AccountSettings" />
</application>
</manifest>

You need
<category android:name="android.intent.category.LAUNCHER" />
within the activity tag for MainActivity.
<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>

Define MainActivity as,
<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>
and all other activities as,
<activity
android:name=".ActivityA"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Launcher Activity is opened first and then the Default Activities.

Just Replace your manifest with this code..
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.it"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".ActivityA"
android:label="#string/app_name" >
</activity>
<activity android:name=".MainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".GeneralAct" />
<activity android:name=".BackUp" />
<activity android:name=".AccountSettings" />
</application>
</manifest>

<?xml version="1.0" encoding="utf-8"?>
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".yourmainactivityname"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Activity1 -->
<activity android:name=".Activity1" />
<!-- Activity2 -->
<activity android:name=".Activity2 " />
<!-- Activity3 -->
<activity android:name=".Activity3 " />
<!-- Activity4 -->
<activity android:name=".Activity4" />
</application>

The Activity you want to open first must have a intent filter with category description as:
<category android:name="android.intent.category.LAUNCHER"/>
Here is the complete Activity declaration in Android Menifest:
<activity
android:name=".MainActivity"
android:theme="#style/app_theme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

no launcher activity found error

I created very simple activity that displays hello world and a button labled TEST, when i press this button the Toast will display a message and I run this app on the emulator.
the problem is that, when I try to run this app the console displays that
no launcher activity found
and nothing to be displayed on the emulator although the code has no error at all.
manifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.qr00"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
</activity>
</application>
Can anyone tell me how to solve the "no launcher activity found" error?

You need to add
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
So:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.qr00"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

You need to add this Intent in your Menifest file
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
</activity>

you can add this code in your manifest file in activity tag.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".QR00"
android:label="#string/title_activity_qr00" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="QR00" />
</activity>
</application>

add like this
<activity
android:name=".YourclassName"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
