An application crash on Android is one of the most common problems faced by users. The application may closes unexpectedly, hangs on a black screen, does not open at all or throw an error like "The application has stopped". The reasons are varied: from bugs in the app code to conflicts with system settings. But in 90% of cases, the problem can be solved independently, without resorting to the help of a service center.

In this article you will find step-by-step guide to troubleshoot failures - from simple reboots to deep system diagnostics. We will figure out what to do if the application crashes on startup, does not respond to clicks or shows an update error. We will also tell you how to prevent repeated failures and save important data.

1. Rebooting the device is the first step to a solution

It sounds banal, but rebooting the smartphone solves up to 30% of application problems. When the system operates for a long time, temporary files and processes accumulate in memory, which can conflict with apps. This is especially true for devices with 2–4 GB of RAM.

How to reboot correctly Android:

  • 📱 Standard method: hold the power button, select Reboot (or Restart).
  • 🔄 Forced reboot: If the screen is frozen, hold the power button 10–15 secondsuntil the device turns off.
  • 🔋 For devices with a non-removable battery: combination Power + Volume Down (on some models Samsung, Xiaomi).

After reboot, try opening the problematic application again. If the problem persists, go to to the next step.

2. Clearing the cache and application data

Caches are temporary files that speed up the app, but over time they can become damaged or take up too much space, which leads to crashes. Clearing the cache is a safe procedure that does not delete your accounts or settings.

How to clear the cache:

  1. Open Settings → Applications (or Apps).
  2. Find the problematic application in the list and tap on it.
  3. Select Storage (or Storage).
  4. Click Clear cache (Clear Cache).

If clearing the cache did not help, try reset application data (option Clear data or Clear Data). Attention: this will delete all settings, logins and saved files inside the app (for example, downloaded maps in Google Maps or game cache).

☑️ What to do before resetting the application data

Done: 0 / 4

3. Updating the application and system

Crashes often occur. due outdated versions of apps or Android. Developers regularly release patches that correct errors. Check for updates:

For the application:

  • 📲 Open Google Play Market.
  • Tap on your profile avatar → Manage applications and device.
  • Tab Updates are available - find the problematic application and update.

For the system:

  • ⚙️ Go to Settings → System → System update.
  • If an update is available, install it (preferably through Wi-Fi).
⚠️ Attention: On some devices (for example, Huawei without services Google) application updates come through the company store (AppGallery, Galaxy Store). Check it too.
Update type How to check What to do if there are no updates
Application Google Play → Profile → Updates Uninstall and install again
System Android Settings → System → Software update Check on the forums to see if the model has been discontinued
Services Google Play Settings → Applications → Google Play Services Clear service cache

4. Checking rights and conflicts with other apps

Sometimes applications do not have enough permissions to work correctly. For example, Google Maps can crash without access to geolocation, and instant messengers without permission for notifications. How to check:

  1. Open Settings → Applications.
  2. Select the problematic application → Permissions.
  3. Make sure that all necessary rights are enabled (for example, Camera, Microphone, Storage).

Also, failures can cause conflicts with other apps, especially:

  • 🛡️ Antiviruses: Avast, Kaspersky sometimes block legitimate applications.
  • 🔒 Optimizers: Clean Master, CCleaner can aggressively clear the cache.
  • 🎮 Game accelerators: Game Booster limit background processes.

Solution: temporarily disable suspicious apps or add the problematic application to exceptions.

💡

If a crash occurs after installing a new application, try uninstalling it. apps for changing the interface (Launchers, Icon Packs) or modified APK files often conflict.

5. Safe mode and system diagnostics

Safe Mode (Safe Mode) loads Android only with basic services, disabling all third-party applications. If the problematic application works fine in this mode, other software is to blame.

How to start Safe Mode:

  • 🔘 On most devices: hold the button Power, then tap and hold Turn off → confirm the transition to Safe Mode.
  • 📱 On Samsung: when turning off, hold Turn off power → will appear option Safe Mode.

If the application is running in safe mode:

  • ✅ The problem is a conflict with other software. Remove recently installed apps.
  • ❌ If the failure recurs, the system or the application itself is to blame (damaged files, incompatibility with version Android).
⚠️ Attention: In safe mode, widgets, live wallpapers and some functions are disabled (for example, Google Assistant). Don't be alarmed - this normal.

6. Removing and reinstalling the application

If the previous methods did not help, the only option left is radical. solution to delete the application and install it again. This helps when:

  • 🗑️ The application files are damaged (for example, after an incorrect update).
  • 🔄 The settings are lost and cannot be restored.
  • 📥 The application was installed from a third-party source (not Google Play).

How to correctly reinstall:

  1. Delete the application via Settings → Applications or by holding the icon on the main screen.
  2. Restart the device.
  3. Install the application again from Google Play (or official APK, if it is Huawei AppGallery).
  4. Do not restore data from a backup - this may return an error.

For system applications (for example, Google Chrome, YouTube) instead of deleting, use rollback to factory version:

  1. Open Settings → Applications.
  2. Select an application → Three dots (⋮) → Uninstall updates.
What to do if the application is not uninstalled?

Some system applications (for example, Google Play Services) cannot be deleted without root access. In this case, you can only disable them through the settings or use adbcommands for uninstallation.

7. Reset settings to factory settings (last resort)

If none of the methods worked, and the application is critical (for example, banking or work), it remains factory reset. This will erase all data from the device, so use this method only as a last resort.

How to reset:

  1. Back up your important data (Settings → System → Backup).
  2. Go to Settings → System → Reset settings.
  3. Select Delete all data (factory reset).
  4. Confirm the action (you may need to enter a pattern or password).

After the reset:

  • 🔄 Install only the necessary applications (do not restore everything from a backup copy at once).
  • 📥 Check the operation problematic application before installing other apps.
  • 🔍 If the failure occurs again, the problem is in the application itself or incompatibility with your smartphone model.
⚠️ Attention: On some devices (for example, Xiaomi, Realme), resetting through the settings menu does not always delete the data completely. For deep cleaning, use the mode Recovery (press Power + Volume Up with the phone turned off).

8. Alternative solutions for difficult cases

If standard methods do not help, try these advanced methods:

1. Installing an old version of the application

Sometimes new updates contain bugs. On sites like APKMirror you can download previous versions of APK files. Consider the risks:

  • 🔓 Disable automatic updates for this application in Google Play.
  • 🛡️ Check the file hash (for example, via VirusTotal) to avoid viruses.

2. Using ADB for diagnostics

For advanced users: connect the phone to the PC and run the commands:

adb logcat | grep -i "package_name"

This will show error logs. Look for lines with Crash, NullPointerException or ANR (Application Not Responding).

3. Checking system integrity

On some devices (for example, Google Pixel), you can run diagnostics:

##426##

This will open the hardware testing menu. Check sections RAM and Storage.

4. Contacting the developers

If the failure occurs in only one application, report the problem to its developers:

  • 📧 Through the feedback form in Google Play (section Reviews).
  • 🐦 On official social networks (Twitter, Facebook) or on forums (Reddit, 4PDA).
💡

Before using ADB or installing APKs from third-party sources, disable the "Verify applications" option in Settings → Google → Security, otherwise the system may block the installation.

FAQ: Frequently asked questions about application crashes

🔹 Why does the application crash immediately after launch?

The most likely reasons:

  • Damaged cache (try clearing it).
  • Incompatibility with version Android (check requirements in Google Play).
  • Conflict with other software (run in safe mode).
  • Lack of memory (free up space or close background processes).
🔹 Is it possible to restore application data after a reset?

Depends on the type of data:

  • ✅ Synchronized data (for example, progress in games through Google Play Games, contacts, photos in Google Photos) will be restored automatically after logging into your account.
  • ❌ Local files (for example, game saves without cloud synchronization, application settings) will be lost only from a backup copy (if there is one).

For critical data, use apps like Titanium Backup (requires root).

🔹 Why do crashes only occur on Wi-Fi, but everything works on mobile data?

Possible reasons:

  • 📶 Traffic blocking: some routers or providers limit access to application servers (for example, to save traffic). Check the settings Qos or Parental Control on the router.
  • 🔒 DNS problems: try changing the DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in the Wi-Fi settings.
  • 🔄 IPv6 conflict: disable IPv6 in the settings of the router or on your phone (Wi-Fi Settings → Advanced → IP Settings).
🔹 How to find out which application conflicts with the problematic one?

Diagnostic methods:

  1. Safe mode: if everything works in it, third-party software is to blame.
  2. Disable one by one: disable one at a time application (via Settings → Applications → Disable) and check the operation of the problematic app.
  3. System logs: use applications like Logcat Extreme to analyze logs (look for errors with the name of your application package).

Frequent “culprits”: antiviruses, optimizers, VPN clients, apps for changing the interface.

🔹 What to do if a failure occurs in only one game?

Games have specific problems:

  • 🎮 Lack of resources: close background applications (use Settings → Developer → Not save actions to free up memory).
  • 🔧 Graphics settings: in the game menu, lower the graphics quality and disable unnecessary effects.
  • 🖥️ Emulation: some games (for example, Genshin Impact) require 64-bit architecture. Check support on the developer's website.
  • 🔄 Server problems: monitor the status of the game servers on sites like Downdetector.

If the game crashes on loading screen - delete the save file (usually located in /Android/data/package name/).
