How to Fix App Not Installed Error on Android Phone?

Fix the annoying problem of App not installed error on Android with this simple solutions and install the problematic app.

Android system is great when it comes to using Apps and enjoy seamless smartphone experience. Many times you may get annoying messages while you install Apps on your device, especially apps from ‘unknown sources’. One such message is ‘App Not Installed’ or ‘Application not Installed’. And it is a common issue faced by Android KitKat, Lollipop, Marshmallow etc. There are mainly 3 possible reasons for the error of installation.

  1. The App build may have corrupted or some of the core files have been modified knowingly or unknowingly.
  2. Android Manifest is the set of permissions has a lot of permissions where an error might have occurred.
  3. Gradle file – The problem might be in the file itself. Just check the minimum SDK version is suitable for your device.
  4. Installing an unsigned app could also result in this error.

Methods to Fix App Not Installed Error

Here are some of the best solutions to fix Application not Installed error on Android.

1. Change App Codes

You can make some changes in the version code or SDK to do so.

Step 1: Download APK Editor app from Google Play Store.

Step 2: Now open APK Editor App and click on ”Select APK from APP” or “Select an Apk File”

Step 5: Now look for the App and click on “common edit”.

Step 7: Apply the changes in APK Editor App.

Step 8: Uninstall any similar pre-installed app and install the modified App from APK Editor.

2. Sign the Unsigned App

  2. Launch the app.
  3.  You will see the app dashboard. You will see the dashboard,

     4. Now, tap on Choose input/output and locate the apk file

     5. Then tap on ‘Sign the file’.

     6. Let the process be complete and then install the signed apk.

3. Reset All the App Preference

  3. check for All Apps.

4. Avoid Installation from SD Card

If the APK is downloaded or if you are trying to install it from external mount than in many cases it would be not possible due to contamination of the file. The installer may not completely parse the package from an mounted storage.

The best solution, in this case, is to download the APK onto your internal storage and try installing the App. Your mobiles package installer will accept the files without any errors.

5. Use an older version of the App

Any latest version of the App may not support your device due to system limitations. Just download any older version of the App. If this works then your device is not capable to read the latest APK.

6. Clear Data and Cache of Package Installer

  1. Open setting on your Android device.
  2. Look for the option called Apps or Manage apps and tap on it.
  3. Check for the Package Installer App under system Apps
  4. You will find two option of Clear data and Clear cache. (For Android Marshmallow 6.0 users check for option Storage to clear data and cache)
  5. Clear the data and cache to solve the problem.

7. Allow Apps from Unknown Sources

This is the most common issue which could cause the error on mobile or tablet.

Go to Settings → Security → Unknown Sources. Enable Unknown Sources. And then try installing App.

8. For Root Devices

If you have a rooted phone than the success rate increases manifolds.

  1. Download and open any root explorer app on your rooted device.
  2. Copy the Apk then go to system >app and grant permissions to the app.
  3. You will see App installed on your device.

Using Lucky Patcher

  • Download, install and open Lucky Patcher (Google Search to Download File)
  • Tap the option Toolbox
  • Click Patch to android
  • Check “Signature Verification status always true” and “Disable apk Signature Verification” and Apply.
  • Reboot your device if not automatically rebooted.

9. Clear Storage/Set Path

Clear some storage space on the device. Make sure SD Card has properly mounted if the file in located in SD Card.

I also recommend downloading the file in internal storage as downloading some types of APK files in external storage may sometimes cause issues due to improper read by package installer of Android OS.

Download the file from any other source in case the file itself is corrupted.

10. Other Miscellaneous Fixes

  • Delete .android_secure/smdl2tmpl.asec file from your SD Card.
  • Reboot the phone and even remove the battery if possible.
  • Uninstall all previous versions of the app or apps with same resemblance currently installed on your device.
  • Remove the SD card and also do not connect your device to a PC while you install the apk.
  • Free up some space, uninstall unnecessary apps.
