What is the hidden Activity Launcher?
The hidden Activity Launcher is a feature in the Android operating system that allows users to access and launch specific activities or functions within apps that are not readily accessible through the regular user interface. It can be a useful tool for advanced users and developers to explore and access certain features or settings that are typically not exposed to the average user. Here’s how you can access the hidden Activity Launcher on an Android device:
1. Start by unlocking your Android device and navigating to the home screen.
2. Tap and hold on an empty area of the screen to open the widgets and wallpapers options.
3. Look for the “Widgets” or “Add Widgets” option, usually accessible by swiping left or right on the screen.
4. Scroll through the widget options until you find the “Settings” widget. It usually displays a gear icon.
5. Drag the “Settings” widget to an empty area on the home screen. This will create a shortcut to the device’s settings.
6. Tap on the newly created “Settings” shortcut on the home screen. It will open a list of available settings.
7. Scroll through the list of settings until you find the “Activity Launcher” option. Tap on it to open the hidden Activity Launcher.
Note: The steps to access the hidden Activity Launcher may vary slightly depending on the Android device and version of the operating system you are using. It’s always a good idea to consult your device’s user manual or search for specific instructions based on your device model to ensure accurate results.
Once you have accessed the hidden Activity Launcher, you can explore various activities or hidden features within apps. Keep in mind that these hidden activities are not intended for general use and accessing them may have unintended consequences. It’s recommended to exercise caution and only modify or interact with activities you fully understand.
How to find launchable activity in apk?
When it comes to finding the launchable activity in an APK file, there are a few steps you can follow:
1. Extract APK Contents: Start by extracting the contents of the APK file. You can do this using a file extraction tool like WinRAR or by changing the file extension from .apk to .zip and extracting it using any standard file compression software.
2. Analyze the Manifest File: Once you have extracted the contents, look for the AndroidManifest.xml file within the APK. This file contains important information about the application, including the launchable activities.
3. Decode the Manifest File: The AndroidManifest.xml file is typically encoded in binary format. To read its contents, you will need to decode it using a tool like apktool or AXMLPrinter2. These tools will help you convert the binary format into a readable format.
4. Locate the Launchable Activity: After decoding the manifest, you can open the resulting file using a text editor. Look for the tags within the file. Each activity represents a specific screen or functionality within the application. You are interested in finding the activity with the intent filter category set as “android.intent.category.LAUNCHER”. This indicates that it is the launchable activity for the application.
5. Retrieve the Activity Name: Within the launchable activity tag, you will find the android:name attribute. This attribute contains the name of the activity class, which usually ends with “Activity” (e.g., MainActivity, SplashScreenActivity). This is the name you can use to access the activity programmatically.
By following these steps, you should be able to locate the launchable activity within the APK file and retrieve the activity name. Remember to always comply with legal and ethical guidelines when extracting and analyzing APK files.
How do I find hidden launcher on Android?
To find a hidden launcher on Android, you can follow these steps:
1. Check the app drawer: In most cases, hidden launchers can be found within the app drawer. Swipe up from the bottom of the home screen or tap the “Apps” button to access the app drawer. Look for any unfamiliar or unnamed app icons that may indicate the presence of a hidden launcher.
2. Search through installed apps: Navigate to the device’s Settings menu and select “Apps” or “Applications.” This will display a list of all installed applications. Look for any suspicious or unfamiliar apps that you don’t recall installing. Sometimes hidden launchers disguise themselves as legitimate apps.
3. Examine system apps: Some hidden launchers may be disguised as system apps. To check this, go to the device’s Settings, select “Apps” or “Applications,” and tap on the three-dot menu icon. Choose “Show system apps” or a similar option to display all installed system apps. Look for any system apps with generic or unfamiliar names that might be the hidden launcher.
4. Investigate app permissions: To identify potentially hidden launchers, review the permissions granted to installed apps. Go to the device’s Settings, select “Apps” or “Applications,” and choose an app to review its permissions. Pay attention to apps that have excessive permissions or permissions that seem unrelated to the app’s functionality. This might indicate a hidden launcher.
5. Use third-party apps: If the above methods don’t yield any results, you can try using third-party apps specifically designed to detect hidden launchers. These apps can scan your device for any hidden or malware-infected apps that may be acting as launchers. Some popular options include Malwarebytes, Avast, or Norton Mobile Security.
Remember, the steps above are for general guidance, and the availability of hidden launchers may vary depending on the specific Android device and its firmware. If you suspect the presence of a hidden launcher, it’s always a good idea to keep your device’s software up to date, regularly review and uninstall unwanted or suspicious apps, and prioritize downloading apps from trusted sources, such as the Google Play Store.

How do I set an activity to launcher activity?
To set an activity as the launcher activity on an Android device, you need to perform the following steps:
1. Open the AndroidManifest.xml file of your Android project.
2. Find the activity that you want to set as the launcher activity.
3. Add the following intent filter inside the activity block:
4. Save the changes made to the AndroidManifest.xml file.
By adding the intent filter with the “android.intent.action.MAIN” action and “android.intent.category.LAUNCHER” category, you are signaling to the Android system that this particular activity should be the entry point of your application. This means that when the user taps on the application icon, this activity will be launched.
It’s worth noting that if you have multiple activities with the MAIN and LAUNCHER intent filters, the activity defined first will be set as the launcher activity by default. However, you can change the launcher activity by reordering the activities in the AndroidManifest.xml file.
Make sure to test your application after making these changes to ensure that the set activity is indeed launched as the starting point of your application.
