INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package signatures do not match the previously installed version; ignoring

Ask Question

I get this error when trying generate a debug apk for update an app directly on the device (Android - React Native):

Execution failed for task ':app:installDebug'.

com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package prensa.com signatures do not match the previously installed version; ignoring!

Im sure that version code and version name were incremented and the package name is the same.

Also, the keystore and other keys are same used before.

Where is the error?

It means you already have it installed. Try removing the old instance of the app and reinstalling. – Dan Apr 10, 2018 at 15:51 The app on device has version code 1 and version name 1.0. The new apk has version code 2 and version name 1.1. It should update it ¿right? – Jhonmer Araujo Apr 10, 2018 at 17:43 Unfortunately not, it doesn't go on version numbers/names it goes on package name. Installing two apps with the same package name will simply not be allowed. – Dan Apr 11, 2018 at 8:07

Just in case if somehow your old application is not removed 100% or its data is not removed.

adb uninstall "com.yourapp.yourapp"
Make sure you know which device adb is dealing with.
I had multiple devices available. I couldn't understand why uninstalling on my emulator didn't get rid of the message. It turned out that my hardware phone was plugged into the computer to charge, and also had USB debugging enabled which was confusing adb.
Disabling USB debugging on my hardware phone, and uninstalling the app on the emulator got it sorted.
I met the same error today.And I found thishttp://blog.bihe0832.com/android-v2-issue.html.It's in Chinese.The key points describe below:
  After package your apk file, unzip it,check the file
  META-INF/ANY-NAME.SF.I sign the apk with jarsigner command line
  tool.I found that the alias putted after the jar-file when exec the
  jarsigner, will used as the ANY-NAME.Then open the ANY-NAME.SF, if
  you found a line of X-Android-APK-Signed: 2,That's the cause of the
  error.Resign your apk,if the line of code gone, the apk will be
  installed success.
for me this was because i tried installing a debug version on a phone that already had a production version installed. in other words, the installed app was signed with the release.keystore file, while the debug version is signed with debug.keystore file.
so i just uninstalled the app so that it could install the app that was signed with debug.keystore file.
INSTALL_FAILED_UPDATE_INCOMPATIBLE
Please uninstall your Previous APk and install again updated APK
gradlew clean
npm start -- --reset-cache
react-native run-android
                gradlew clean is a bit confusing. From project directory run cd android && ./gradlew clean.

If you already install app on your device, please uninstall it by delete your app and rerun npx react-native run-android again.
hope this helpful.
