APK installation failed: [INSTALL_FAILED_VERIFICATION_FAILURE]

Question

I'm trying to install an APK on a device running an AOSP build of Jelly Bean (4.2).

When I "adb install my.apk", I get the error:

[INSTALL_FAILED_VERIFICATION_FAILURE]

I've tried using "testsign.jar" to "sign" the apk but it does not change the outcome

Is "allow unsigned applications" enabled under settings-> security? — Cookster

That setting does not exist, but the "Unknown sources" checkbox is checked... — dcarr622

You need to disable verification of the APK during ADB install. If the setting in Security is greyed out or isn't working as it should try shelling into the device and, depending on which settings database the setting is in per your API level (Global, System, Secure) run

$ adb shell settings put global verifier_verify_adb_installs 0

If you can actually set it, it will prevent checking of APKs over ADB.

Sometimes you will need to disable the package verifier as well using:

$ adb shell settings put global package_verifier_enable 0

On KitKat, you can see here that these settings are in the Global database:

This is helpful but is missing where exactly I needed to put in that command. Thanks to this answer I found the missing step.

Could you please explain what does "verify APK" means here? Is it signature verification? My app seems to have a one (And there is not any apk without any signature I think)

mjs Over a year ago

"Verification" also requires network, so if you have airplane mode turned on, it will also fail.

Go to developer settings and disable verify apps via USB. Then you can install .apk without any problem.

This what worked for, I was trying to install on device with android 6.0

Settings > Developer Options > Then Turn off Verify Apps over USB See first image

Then

Settings > Security > Then Turn on Unknown sources

Finally

Do not forget to uninstall your app and start afresh.

Got to Settings > Developer Options > Then Turn off Verify Apps over

Settings > Security > Then Turn on Unknown sources

Worked for me. Only step 1 is insufficient, step 2 is also needed. This is the correct answer.

The actual problem is Google play block your app! You need to turn off that

Go to the play store
Open the drawer and select Play Protect
Open the settings and turn off both Scan apps with play protect and Improve harmful app detection
Now it's your turn. Rebuild your app and launch it! Good Luck!

UPDATED ANSWER: with the last Android updates, now the following error may show during installation of the APK because of Play Protect:

Failed to finalize session : INSTALL_FAILED_VERIFICATION_FAILURE
Session 'app': Error Installing APKs

In order to fix this (for developer purposes), you may disable Play Protect as it is shown here: installation app blocked by play protect.

You have to allow unsigned applications. The install is being blocked by Android. Allow install of non-market apps in Settings.

Where is this setting? There is a "verify apps" checkbox, but it's unchecked. i.imgur.com/AX20lnG.png

It's also greyed out...not sure what that means

Are you tethered with USB? Is USB Debugging enabled?

Cookster Over a year ago

Is the application already installed? It will show this when they are signed differently.

Mr. Developerdude Over a year ago

+1 for all the great suggestions. And here is mine: are you sure there is enough space wherever you are trying to install it?

Aside from "settings put global verifier_verify_adb_installs 0", I also need to set package_verifier_enable to 0 in my case to make it work.

e.g.

adb shell

settings put global package_verifier_enable 0

None of the suggestions above worked for me, however factory resetting the device did the trick.

As someone said, you need to have a signed apk to run it.In order to have a signed apk, right click on your project>Android tools>Export signed application package.You will then be prompted to locate your keystore, but if you don't have you can create one.Follow the next steps as guided by eclipse.

You can do this without any instructions like this: Go to settings on your device and then develooper setting and disable the option to confirm apps via usb. (Translation with google translate)

This happened to me in Android Studio after I reinstalled the OS on my PC - I was trying to test a build on a tablet. What ended up working for me was simply uninstalling the application on the tablet (built by the previous installation).

could you be a bit more specific as how to do that? I don't see anything that says "app debug" under developer settings. the closest I see is "Debugging > Select debug app" which doesn't pop up anything helpful.

I faced this issue, for me it was because the developer's option was not enabled for my emulator. you can enable it from settings as we do for real devices.

For Android 14+ you might need to bypass the target check with --bypass-low-target-sdk-block:

adb install --bypass-low-target-sdk-block "myapk.apk"
