How can I find out from many class file that the particular file is the activity which was created at the time of creating the project?
There is must one Activity as Launcher.
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
It need to define in AndroidManifest.xml so check your AndroidManifest.xml and you could see one launcher activity..
I seen your AndroidManifest.xml which you given link in this case may be DialtactsActivity or DialtactsContactsEntryActivity launcher activity
I don't know if that is what you mean:
In your manifest:
<activity android:name=".mainActivity" android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar"> //THIS IS MAIN BECAUSE THERE IS INTENT_FILTER
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Activity1" android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar" />
<activity android:name=".Activity12" android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar" />
<activity android:name=".Activity123" android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar" />
<activity android:name=".MyProfileActivity" android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar" />

I made a splash screen class name Splash.class . I didnt make in mainacitivity so how i can I show this at first screen (Opening screen or first screen)
Manifest
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.LoginApp">
<activity
android:name=".second"
android:exported="true"></activity>
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
In order to launch the splash screen first, you have to specify the type of intent by using <intent-filter>. So, adding the below attributes to the activity in your AndroidManifest.xml file will make it launch first:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
In the end, your manifest will look something like this:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.LoginApp">
<activity
android:name=".second"
android:exported="true"></activity>
<activity
android:name=".MainActivity"
android:exported="true" />
<activity
android:name=".Splash"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</application>
</manifest>
change your manifest like this
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.LoginApp">
<activity
android:name=".second"
android:exported="true"></activity>
<activity
android:name="com.your.package.Splash" //put yout class here
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
First time your android will run activity with category LAUNCHER, so change your activity class in category.LAUNCHER with your class (Splash.java)
I want know how i can determine which activity begins when i launch application ?
I have two Activity. MainActivity and Activity2. Which is the way i can code my application start every time in MainActivity ?
<activity
android:name=".MainActivity"
android:label="#string/app_name"
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=".Activity2"
android:label="#string/app_name"
android:screenOrientation="portrait"/>
<activity
Check out your AndroidManifest.xml file. In there you have each of your activities listed, then you can simply specify which one you'd like to be the default startup by adding this "intent-filter" shown below.
<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
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".precus"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="com.yair.guessit.PRECUS" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="Customize"
android:label="#string/app_name"
android:screenOrientation="portrait" >
</activity>
<activity
android:name="FirstPage"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="com.yair.guessit.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
this is my manifest up there, and the app dont open .
can someone explain me how to set up the manifest with all the activites?
the precus is the first for now to open when the app open.
at the precus activity there is a intent that when the button get clicked its Customize activity.
why its not working?
change this line in your file
<action android:name="com.yair.guessit.PRECUS" />
to
<action android:name="android.intent.action.MAIN"/>
then run it.
if it work fine. then mark it as an accepted answer.
Your application has all Activities with intent-filter .Main... Let only one to have this filter, in others - just delete intent-filteres like...
<activity
android:name="FirstPage"
android:label="#string/app_name"
android:screenOrientation="portrait" >
</activity>
So I have an app, with 2 activities. For some reason I am getting 2 launcher icons, one for each activity, but I only want one!
The Game activity had an intent-filter which i removed. I also uninstalled the app and reinstalled it from scratch but its still coming up with both launchers :(
Manifest below
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".Game"
android:label="#string/title_activity_game" >
</activity>
</application>
You need to remove the label tag from your second Activity.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".Game" >
</activity>
</application>
I have just started to develop a brand new application and I have two Activities set up one which displays the Splash Screen and another the Main one. Here is the manifest file:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".Main"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.SPLASH" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I tried changing android.intent.action also removing the DEFAULT Category line from Main also placing the Splash Activity setup above main.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".Main"
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=".Splash"
android:label="#string/app_name" >
</activity>
</application>
Just realized the .MAIN in action and .LAUNCHER should be in the same activity , it's working now!
check this
Android: No Launcher activity found! was working before
