Troubleshooting Intune: App Installation Failures Post Android APK Update
This article focuses on resolving a common issue where users encounter the App installation failed error message on their Android devices following an update to an Android APK application within the Microsoft Intune portal. While the core problem identified in a specific scenario involves user action, understanding the broader context of Intune app deployment and troubleshooting is crucial for effective resolution.
Symptoms of Failure¶
The primary symptom of this issue is the explicit App installation failed notification appearing on the user’s Android device. This occurs after an administrator has uploaded an updated version of an Android Line-of-Business (LOB) application (packaged as an APK file) to the Intune portal and assigned it to a group of users. Devices belonging to users within this assignment group will attempt to install or update the application, and if the process fails, this clear error message is displayed to the user. This symptom indicates that the Intune service initiated an action on the device related to the application, but the action could not be completed successfully.
Beyond the device notification, administrators can also observe these failures within the Intune portal. By navigating to the specific application and reviewing its device status or user status, administrators can see which devices or users reported installation failures. The portal often provides more detailed status information, sometimes including error codes, which can offer further clues about the root cause of the problem.
Understanding the Specific Cause¶
In the particular scenario highlighted, the root cause of the “App installation failed” error after updating an Android LOB APK in Intune is surprisingly straightforward: the end-user had previously uninstalled the application from their Android device.
When an administrator updates an LOB app in Intune, the service instructs the assigned devices to install the new version. If the application is already present, the device’s operating system handles the update process. However, if the user has removed the application, the system attempts to perform an update operation on an app that no longer exists on the device. This mismatch between the requested action (update) and the device’s current state (app not installed) results in the failure. The Intune service, receiving feedback from the device’s management agent (typically the Company Portal app), reports this as an installation or update failure because the intended state could not be achieved. This specific cause emphasizes the importance of understanding user interaction with assigned applications, especially for LOB apps which might not be mandatory or frequently used.
Solution for the Specific Cause¶
Addressing the specific scenario where the user uninstalled the app requires direct user action. The simplest and most effective solution is to instruct the user to reinstall the application from the Company Portal on their Android device.
Here’s why this works:
1. The Company Portal acts as the user’s interface to the Intune service on the device.
2. When the user opens the Company Portal, it displays the applications assigned to them, including LOB apps.
3. Even if the Intune service previously tried and failed to update the app because it was missing, the presence of the app assignment in Intune means the app is still listed as available for installation in the Company Portal.
4. By selecting the app and initiating an installation (rather than an update attempt by the system), the device correctly handles the deployment of the latest version of the APK file made available through Intune.
This user-initiated reinstallation bypasses the failed update scenario by starting fresh with a new installation of the current version. It’s a quick fix but relies on user compliance.
Broader Troubleshooting for Intune App Failures¶
While the user uninstall scenario is one cause, “App installation failed” is a generic error message in Intune that can stem from numerous other issues. Effective troubleshooting requires a systematic approach.
Common Causes Beyond User Uninstall¶
Understanding other potential culprits is vital for diagnosing failures when the user hasn’t uninstalled the app:
- Network Connectivity Issues: The device must be able to reach the Intune service and the distribution point where the application package is stored. Poor Wi-Fi, cellular data issues, or firewall restrictions can prevent the APK from downloading.
- Insufficient Device Storage: Android devices require adequate free space to download, stage, and install applications. If the device is low on storage, the installation will fail.
- App Package Issues:
- Corrupt APK: The uploaded APK file might be damaged or incomplete.
- Signing Issues: Android applications must be signed. If the signing is incorrect or inconsistent (especially when updating), the installation might fail. For LOB apps, maintaining consistent signing keys across versions is critical for updates to succeed.
- App Compatibility: The application might not be compatible with the device’s Android version, architecture (e.g., ARM vs. x86), or specific hardware requirements.
- Manifest Errors: Errors within the application’s
AndroidManifest.xmlfile can cause installation failures.
- Device Restrictions or Policies: Intune policies might be inadvertently blocking app installations from unknown sources (though Company Portal installations are typically trusted) or other security restrictions could interfere. Device compliance status or conditional access policies might also play a role.
- Company Portal or Intune Agent Issues: The Company Portal app or the underlying Intune management components on the device might be outdated, corrupted, or malfunctioning.
- Assignment or Policy Conflicts: Conflicting assignments (e.g., assigning the same app multiple times with different settings) or policy conflicts could lead to unexpected behavior.
- Service Issues: Rarely, temporary issues with the Intune service itself or associated Microsoft services could cause deployment problems.
A Structured Troubleshooting Methodology¶
When facing Intune app installation failures, consider these steps:
Step 1: Verify the Assignment and Targeting¶
- Confirm that the user and device are correctly included in the assigned group for the application.
- Check if the assignment is set to “Required” (for automatic installation) or “Available” (requires user initiation from Company Portal). The issue described in the source is more typical of a “Required” assignment where the system tries to push the update.
- Review any exclusion groups to ensure the user/device is not accidentally excluded.
Step 2: Examine Intune Portal Monitoring¶
- Navigate to
Apps>All appsin the Intune portal. - Select the problematic application.
- Go to
Device install statusandUser install status. - Filter by the user or device experiencing the issue.
- Look for the specific error details or error codes provided. These codes are often the most valuable clue and can be looked up in Microsoft documentation for specific meanings.
Step 3: Check the Device State¶
- Confirm the device is enrolled in Intune and is checking in regularly.
- Verify the device’s Android OS version meets the app’s requirements.
- Check the available storage space on the device.
- Ensure the device has a stable network connection. Test connectivity to external resources or internal network resources if the app requires them.
Step 4: Inspect Company Portal and Device Logs¶
- On the Android device, open the Company Portal app.
- Access the settings or help section (the location varies slightly by version).
- Look for an option to “Upload Logs” or “Email Diagnostic Logs”. Uploading logs allows Microsoft support (if engaged) to analyze detailed activity.
- More advanced troubleshooting might involve using Android Debug Bridge (ADB) to pull system logs (
logcat) for more granular details, though this is typically reserved for deeper investigation. Look for log entries related toIntune,CompanyPortal, or the application’s package name during the time of the failed installation attempt.
Step 5: Re-attempt Installation/Update¶
- For Required assignments: Force a device sync from the Company Portal app on the device or from the Intune portal (
Devices>Android> select device >Sync). This prompts the device to check for new policies and app assignments. - For Available assignments: Instruct the user to open the Company Portal and attempt to install the app manually. This is the specific solution for the user-uninstall scenario but is also a general troubleshooting step.
Step 6: Re-upload or Re-create the App Package¶
- If you suspect the APK file is corrupt or has signing issues, try downloading the original APK again from its source or build system.
- Delete the application entry from Intune and re-upload the fresh APK file as a new LOB application. Reassign it to a small test group first. Note that deleting and re-adding an LOB app will typically require a full reinstallation on all devices, not just an update.
Step 7: Review App Dependencies and Permissions¶
- Does the app require specific Android permissions that the device policy might restrict?
- Does the app depend on other applications or services being installed or configured first?

Relevant Information and Best Practices¶
- App Signing: For LOB apps, always use the same signing key to sign new versions. Changing the signing key requires users to uninstall the old version manually before installing the new one, which is disruptive.
- Versioning: Ensure the version code and version name in the APK’s manifest are correctly incremented with each update. Android uses these to determine if a new version is available.
- Testing: Always test LOB app updates on a pilot group of devices before deploying to a larger audience.
- Communication: Inform users about upcoming app updates and provide instructions, especially if there’s a possibility they might need to take action (like reinstalling).
- Monitoring Strategy: Regularly review app installation status reports in the Intune portal to proactively identify widespread issues before they impact many users.
- Consider Managed Google Play: For apps available on Google Play (even private/internal ones deployed via Managed Google Play), updates are handled directly by the Google Play store services on the device, which can sometimes be more reliable than LOB deployments for standard apps. This doesn’t apply to apps only distributed as APKs outside of the Play Store ecosystem.

Example of Intune Monitoring Detail¶
Within the Intune portal’s app monitoring section, a failed installation might show status details like:
- Status: Failed
- Status details: See error details
- Error code:
0x87D13B64(Example - this specific code relates to an app already being installed with a conflicting signature or version) - Error description: The app could not be installed. This could be due to a variety of factors, including insufficient storage, device compatibility issues, or problems with the app package.
Looking up such error codes in Microsoft’s Intune documentation is a crucial step in diagnosing the specific problem.
Conclusion¶
Troubleshooting Intune app installation failures on Android can involve several potential causes. While a user uninstalling an LOB app before an update is a specific scenario leading to the “App installation failed” error, administrators must be prepared to investigate broader issues like network problems, storage limitations, app package integrity, or device configuration conflicts. By utilizing the monitoring tools within the Intune portal, examining device states, checking logs, and following a structured troubleshooting process, administrators can effectively diagnose and resolve most app deployment issues. Empowering users with knowledge about the Company Portal and knowing when to ask them to simply reinstall the app is also a valuable tool in the troubleshooting arsenal.
