Android_Install failed version downgrade

Question

I'm going to update my apk on GooglePlay Store and I know that i have to upgrade the version code and name in manifest file however, it made install_failed.

Installation error: INSTALL_FAILED_VERSION_DOWNGRADE 

Please check logcat output for more details. Launch canceled!

I modified the version code and name like this: android:versionCode="2" android:versionName="1.0.5"

Did i make it wrong?

Solution 1

Just uninstall the application on your device first and then install the fresh one.

Solution 2

When you are installing via adb you can pass -d to allow version downgrade

adb install -d -r your.apk

-r will also replace the existing app

Solution 3

Installation error: INSTALL_FAILED_VERSION_DOWNGRADE Please check logcat output for more details. Launch canceled!

I solved it by using the command prompt,navigating to project folder >adb uninstall package (you can get the package from Manifest.xml file).

In my case : D:\projectFolder\AndriodApp>adb uninstall com.example.app

Again launch the App in emulator or mobile.

Solution 4

just use this:

$ adb -e uninstall your.application.package.name

Solution 5

Apparently the versionCode of your currently installed version of the application is greater than 2, thus resulting in a failed installation on the device.

I made the version code to "105" however i got a dialog "Error, please restart application error code : 20 " on my device. I can't find error on Logcat. Do you have any idea with it? I have no clue.

Please explain your solution.

Great, but exactly where is that versionCode to be found?

1)Programmatically by manifest file to increment versions. 2)Earlier versions in production go stackoverflow.com/questions/14470402/…

This command executes an uninstall on a running emulator instance. This doesn't answer the question.

This sped up my db migration testing by a factor of 2! Thank you

[Roberto Rodriguez]

Perfect. You made my day. Thanks

You should drop the -e flag when not using an emulator.

[Steven Mark Ford]

Sometimes a device restart is also required after doing this.

Since Android 7 (Nougat), for security reasons, adb install -d no longer works unless the package is marked as debuggable.

This will erase any configuration i have in my application. I preffer use adb install -d -r your.apk as said @kemuri.
