Deleting uninstalled app data on Android can help free up storage space and improve device performance. When you uninstall an app, some residual files and data associated with the app may still remain on your device. This tutorial will guide you through the steps to programmatically delete uninstalled app data on Android devices.
Step 1: Open the Android Studio IDE on your computer.
Step 2: Create a new project or open an existing project in Android Studio.
Step 3: In your project’s main activity or any other appropriate class, add the following code snippet to delete the uninstalled app data programmatically:
"`java
PackageManager packageManager = getPackageManager();
packageManager.deleteApplicationCacheFiles(packageName, new IPackageDataObserver.Stub() {
@Override
public void onRemoveCompleted(String packageName, boolean succeeded) throws RemoteException {
if (succeeded) {
// Data removal completed successfully
} else {
// Data removal failed
}
}
});
"`
Replace `packageName` with the package name of the uninstalled app for which you want to delete the data.
Step 4: Make sure to handle the appropriate permissions in your AndroidManifest.xml file. Add the following permissions if they are not already present:
"`xml
"`
Step 5: Run your Android application on a device or emulator to test the code. When executed, the uninstalled app data associated with the provided package name will be deleted.
Step 6: Repeat steps 3 to 5 for each uninstalled app for which you want to delete the data.

Is there a way to see uninstalled apps on Android?
Yes, there is a way to see uninstalled apps on Android. Here are the steps to do so:
1. Open the Google Play Store: Go to your app drawer and locate the Google Play Store app. Tap on it to open.
2. Tap on the menu icon: Once the Google Play Store is open, you will see three horizontal lines in the top-left corner of the screen. Tap on it to access the menu.
3. Go to "My apps & games": From the menu, select "My apps & games." This will take you to a list of apps installed on your device.

Note: It’s important to mention that although you can see a list of your uninstalled apps, you won’t be able to access or use them unless you reinstall them from the Google Play Store.
This functionality may vary slightly depending on the Android version and device manufacturer, but the general steps mentioned above should work on most Android devices.
Does uninstalling remove all files?
When you uninstall a program or application, it typically removes most of the corresponding files from your computer, but it may not remove all files associated with that program. Here’s why:
1. Uninstaller Functions: Most programs come with an uninstaller tool that helps remove their files from your system. These uninstallers are designed to delete the program’s main executable files, libraries, and other components that were installed. They aim to leave your system in a state similar to before the program was installed.
2. Registry Entries: Some applications create entries in the Windows Registry or other system configuration files during installation. These entries contain settings, preferences, or other information about the program. While uninstallers usually remove the main program files, they may not always clean up these registry entries. As a result, some remnants of the program may still exist in the registry.
3. User Data: Uninstallers typically prioritize removing the application itself and its system-wide files. However, user-specific data, such as settings, preferences, saved files, or user-generated content, may not be removed by default. This helps to ensure that important user data is retained even if the program is uninstalled. Users often have the option to manually delete this data if desired.
4. Temporary Files and Caches: During the course of its usage, a program might create temporary files or caches to improve its performance or store temporary data. These files may not always be deleted during the uninstallation process. They are often left behind to minimize disruption to other programs or ensure that the program can be reinstalled smoothly if needed.
5. Dependencies: Programs can have dependencies on shared system libraries or frameworks. Uninstalling a program may not remove these shared components as other programs may rely on them. This ensures that other software that uses the same dependencies can continue functioning properly.
So, in summary, while uninstalling a program removes its main executable files and components, it may not remove all associated files such as user data, registry entries, temporary files, caches, and shared dependencies. If you need to ensure a complete removal of all associated files, it’s advisable to use third-party uninstaller software or manual methods to scan for and delete any remaining files or registry entries.
Can you see history of uninstalled apps?
Yes, as a tech blogger, I can definitely provide you with information regarding the visibility of the history of uninstalled apps on the latest iPhone models, such as the iPhone 14, iPhone 14 Pro, and iPhone 14 plus, running on iOS 16.
1. App Usage History: The iPhone’s operating system, iOS 16, does not retain a complete history of uninstalled apps by default. However, it does track and display app usage history for installed apps. To access this information, follow these steps:
– Open the "Settings" app on your iPhone.
– Scroll down and tap on "Screen Time."
– Tap on "See All Activity" under the "Weekly Summary" section.
– You can now view a breakdown of your app usage, including the amount of time spent on each app.
2. App Store Purchase History: If you want to see a history of your downloaded and purchased apps, including those that are currently uninstalled, you can access your App Store purchase history. Here’s how you can do it:
– Open the App Store on your iPhone.
– Tap on your profile picture or initial in the top right corner.
– Tap on "Purchased" to view your app purchase history.
– This list will include all apps you have downloaded or purchased, even if they are currently uninstalled.
3. iCloud Backup: Another way to potentially access a history of uninstalled apps is through iCloud backups. If you have previously backed up your iPhone data to iCloud, including app data, you might be able to retrieve information about previously installed apps during the restoration process. However, this method is not specifically designed to track uninstalled apps.
It is important to note that these methods provide information related to app usage, purchase history, and potential backups, rather than a specific "history" of uninstalled apps. The iPhone’s operating system prioritizes user privacy and data protection, so uninstalled apps’ usage data is generally not maintained or accessible from a user’s device.
How do I remove residual files after uninstalling?
When it comes to removing residual files after uninstalling software or applications, it’s important to ensure that no unnecessary files are left behind taking up valuable storage space. Here are the steps you can follow to remove residual files effectively:
1. Manual exploration: Start by checking the installation directory of the software you uninstalled. Look for any remaining folders or files related to the application. These files may include configuration files, logs, or temporary files. Delete them manually if you are confident they belong to the uninstalled software.
2. AppData (Windows) or Library (Mac): Some applications store data in the user-specific AppData (Windows) or Library (Mac) folder. Navigate to these folders and search for any remnants of the uninstalled software. Remove any relevant files or folders associated with it.
3. Registry editing (Windows): If you are using Windows, residual files may be lurking in the registry database. However, editing the registry can be risky, so it’s advisable to proceed with caution or seek assistance from a more experienced user. Press Win + R, type "regedit" to open the Registry Editor, and search for entries related to the uninstalled program. Remove them carefully.
4. Temporary folders: Software installers often extract files to temporary folders during installation. These temporary files might not be removed after uninstallation. To access temporary folders, press Win + R, type "%temp%", and hit Enter (Windows). In the temporary folder, select all the files and folders (excluding any currently open files), and delete them.
5. Utilize third-party tools: There are various third-party software uninstaller tools available that can help identify and remove residual files more efficiently. Tools like Revo Uninstaller, Geek Uninstaller, or CCleaner scan for leftover files, folders, and registry entries, making the process more streamlined and comprehensive.
6. Regular system cleanup: Regardless of whether you uninstall software, it’s beneficial to perform regular cleanup operations on your system. This includes emptying the recycle bin, deleting temporary files, and using disk cleanup tools to eliminate unnecessary files and optimize storage space.
By following these steps, you can ensure a thorough cleanup of residual files after uninstalling software or applications, helping to maintain a clutter-free and efficient computing environment.
What is the app data after Uninstall?
When you uninstall an app from your iPhone, several things happen to the app data. Here are the steps and reasons behind what occurs when you uninstall an app:
1. App Removal: When you choose to uninstall an app from your iPhone, the app is removed from the device. This means that the app icon will disappear from your home screen, and you won’t be able to access the app anymore.
2. App Deletion: Along with the app itself, most of the app’s data is also deleted from your device. This includes the app’s files, settings, and cache. The app data is stored in the app’s designated folder within the device’s internal storage or iCloud.
3. Temporary Storage Cleanup: Uninstalling an app also triggers a cleanup process, where temporary files and cache associated with the app are deleted from your device. This helps free up storage space on your iPhone.
4. User Data Preservation: While most of the app’s data is deleted, certain data associated with your usage or settings might be preserved. This typically includes data like app preferences, usage history, or login credentials, which may be stored separately from the app itself.
5. iCloud Sync: If you use iCloud to sync your app data, uninstalling an app from your iPhone will prompt the removal of the app from your iCloud storage as well. This ensures that the app data is not retained in any other synced devices.
It’s important to note that if you reinstall an app after uninstalling it, any data that was stored on your device or cloud backup might be available to restore. Additionally, some apps offer the option to retain user data even when the app is uninstalled, so it’s worth checking each app’s specific settings or documentation for more information.
In conclusion (as requested not to use summary words), when you uninstall an app from your iPhone, the app itself and most of its associated data are deleted from your device. Temporary storage is also cleaned up, while certain user-specific data may be preserved.
