Fix App Not Installed As Package Appears To Be Invalid 2023


Nothing to worry about; we have you covered with all the troubleshooting steps to fix the ‘App not installed as package appears invalid’ error. 

Restart Your Phone

Restart

Many times the resolution to the issue may be as simple as restarting your device, and it might save you from the hassle of trying all the possible steps. Try restarting your Android device once, then installing the APK again after restarting. If that fixes the issue, you are good to go, but if it doesn’t, carry on with the next step. 

Ensure You Have Enough Storage

Issues like such are common when there’s not enough storage to install new apps. Ensure you have at least 5GB of minimum storage on your phone to install the app. If you don’t have free storage, try deleting some files and apps you no longer require. Once you have enough storage, try rerunning the installation process. 

Download The App Again

If the app you downloaded got corrupted for some reason, then that can also be the reason behind facing this issue. If you think that’s the real reason behind facing this issue, you can try downloading the app again and installing the newly downloaded APK file. 

Download From Different Sources

If you have downloaded the app again, but the issue is still not gone, then probably the source has the corrupted APK file of the app. You can use some other source to download the APK file of the app. Make sure the source you are using to download the app is reliable to avoid downloading corrupted and malicious files. 

If possible, we recommend you use the Play Store to download the app. Use any other source only if the app is not available on the Play Store and you trust the source you are downloading the file from. 

Verify The Architecture Of Your Device

Apps have different versions built for different architectures. If you try installing an app that is incompatible with your device’s architecture, you will be prompted with an ‘App not installed as package appears to be invalid’ error message. But how can I check the architecture of my device and download the correct app? Here’s how-

  • Open the Play Store on your device. 
  • Here, search for the application named CPU-Z
  • Tap on it from the search result and then tap on Install to install the app.

Disable Google Play Protect

Google Play Protect scans your device for harmful apps and informs you about the action you can take. Also, it scans all the apps you download and installs from third-party sources so that no malicious app is installed. However, it can often show issues with the app even if it is not malicious and downloaded from a trusted source. You can temporarily turn off Google Play Protect while installing the APK and then turn it back on. You can turn off Google Play Protect by following the steps given below-

  • Open the Play Store on your PC.
