when try update my app I get error: Failure INSTALL_FAILED_UPDATE_INCOMPATIBLE

Question

Android 6.0

In my app/build.gradle:

android {
    compileSdkVersion 28

    flavorDimensions "default"
    defaultConfig {
        applicationId "com.myapp"
        minSdkVersion 17
        targetSdkVersion 28
        versionCode 60
        versionName "3.4"

Install from Google play my version (old version). Then I want to test update my sign app by new version of my app (sign apk) like this:

android adb install -r my_app-release.apk

I get error:

adb install -r my_app-release.apk
Performing Push Install
my_app-release: 1 file pushed. 4.5 MB/s (9219518 bytes in 1.946s)
    pkg: /data/local/tmp/my_app-release.apk
Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

P.S. I sign new version of my with same private key as previous version of my app (in Google Play). When I sign APK I select the next signature versions: V1 (jar signature) AND V2(Full APK signature)

I can't remove old version. Because I try to update version from Google Play — Alexei, Aug 23 '19 at 17:24

I found the problem. The old version(in Google Play) of my app was signed by key NOT EQUALS to key that I signed new version of my app.
