I am developing a Huawei custom Theme. I was trying to change some Google apps (Documents, Sheets and Slides) icons. So I used as address their package name e.g. com.google.android.apps.docs.editors.slides
Since it didn't work, I tried with some activities, found in the manifest file, but no one worked yet. (for example com.google.android.apps.editors.homescreen.HomescreenActivity, which is the first one that appears when I open Slides);
So the question is:
is there a way to identify which is the main activity, nay, which is the activity who defines app icon?
Usually, the main activity declares the following intent filters (documentation) in order to indicate for the system that this activity is Main and is a launcher activity:
<activity android:name=".ActivityClassName">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

I want to make my Android application invisible and work through a background task.
This part should work like these two apps, if anyone knows them:
https://www.keeperschildsafety.net/
https://www2.mspy.com/
I already found examples for making the app icon invisible, but I want to go one step further.
This is the site I found that on:
https://readyandroid.wordpress.com/hideunhide-app-icon-programmatically-android/
I also found some explanations that I should delete the <intent-filter>:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
But then I am not able to start my application.
On all other sites I read that this is not possible, but the two examples shown at the top prove that it is actually possible somehow.
I want to start my application once, then hide it and unhide it later.
I already know how to trigger the unhide. The only part that I need is the hiding and unhiding itself.
You need to remove the following line from your AndroidManifest.xml:
<category android:name="android.intent.category.LAUNCHER"/>
This will remove the application from the default launcher. However, you also need to add the following line such that your BroadcastReceiver is not completely ignored:
<category android:name="android.intent.category.DEFAULT"/>
You should NOT remove the line below - it is used to specify which Activity should launch first when your app is opened:
<action android:name="android.intent.action.MAIN"/>
also try this
<activity android:name=".MainActivity"
android:excludeFromRecents="true" ...
in your AndroidManifest.xml's activity declaration.
I have created an app ,for showing the users current location in the startup and another activity for enter a destination,i have used Maps activity for displaying current location,and a intent is passed to another activity when a button is clicked.The problem is it is showing two apk files in the device one for maps activity and another for second activity and when i create a signed apk,the maps activity was not showing nothing ?How can i solve this issue??
I had this issue too. Have a look at the manifest and check if you have multiple rows in the whole manifest containing the
"android.intent.category.LAUNCHER"
In case yes: remove the ones that are not related to the main activity.
The correct template, that is ONLY for the main activity, is the following:
<activity android:name="MainActivity">
<!-- This activity is the main entry, should appear in app launcher -->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I have an application where I need to provide a additional icon acccessible in applications to launch an activity from the same application.
So that when application installs it shows two icons in the applications list, one icon to launch the app is already there, how to have the other icon and then how can I start the required activity from that icon/shortcut.
add this in the manifest file inside the activity tag which you want to show in the launcher
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
I found a code on internet for displaying a splash screen before starting an android application. He made some changes in the code which he didn't explain well.
He used Launcher for Splash screen Activity and used Default in main android Activity.
He used Package name with main class name instead of pre-generated code for android:name in action.
Here is the code.
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".StartingPoint"
android:label="#string/title_activity_starting_point" >
<intent-filter>
<action android:name="com.alfred.splashscreenwithsound.STARTINGPOINT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
So my question
What is the difference between LAUNCHER & DEFAULT.
Is there any good behind changing the android:name in action to the package name.
when you write LAUNCHER it will launch application with Icon and if you remove it it will not show you the application Icon
"android.intent.category.LAUNCHER" serves as our main entry into the app.
android.intent.category.DEFAULT be set if the Activity should be an option for the default action (center press) to perform on a piece of data.
Refer this
LAUNCHER is your main page DEFAULT is your Activity page when load the app. on device first LAUNCHER will open. Then If you trigger your activity page DEFAULT will open.
Instead of declaring a pre-determined launcher activity in my manifest using an intent filter:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Could I, instead, be given programmatic control over the activity which gets run when the application launches?
I'm not able to find anywhere in the documentation which says I must use the intent filter approach... but I also don't see any discussion of the alternative(s).

Thanks.
As far as I know, it's not possible. Android creates or sets up the hard link of the App icons to their respective activities by looking at the manifest. If you don't set it, you will not find any icons/shortcuts for your app after you install it.
