maven-android-plugin and Android Test Project give INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES

Question

I am trying to use the maven-android-plugin to launch InstrumentationTestRunner tests.

I created an App com.my.app.
I created a simple Android Test Project com.my.app.test2.
I made maven use the jarsigner to automatically sign the apks.

For sining I am using the same KeyStore. Anyway I am getting the following error, when I try to execute the test project by doing maven clean install

Failed to execute goal com.jayway.maven.plugins.android.generation2:android-maven-plugin:3.6.0:internal-pre-integration-test (default-internal-pre-integration-test) on project eticapptest2: 42f7a71e823ebff9_samsung_GT-N7105 :   Install of D:\AndroidApp\com.my.app.test2\target\eticapptest2-1.0.0-SNAPSHOT.apk failed - [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES

What I tried:

When I inspect the APKs which are produced and signed during the maven run - I see, that both (the com.my.app.apk and com.my.app.test2.apk) are signed correctly. The certificates are the same.

What could be the reason for the error?

Answer 1

INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES

The error indicates you have a version of the app installed with a different certificate.

Before running mvn clean install, uninstall both the apps:

1. adb uninstall com.my.app
2. adb uninstall com.my.app.test2
