Android Studio The application could not be installed: INSTALL_FAILED_VERIFICATION_FAILURE

Question

Can somebody help me please to understand this error if I try to run Android project in Android Studio + Andy emulator? Error says The application could not be installed: INSTALL_FAILED_VERIFICATION_FAILURE. Its simple application with one spinner widget. This is my MainActivity file

package camo.learn2codeproject3;


import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;
import java.util.ArrayList;


public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener
{

    Spinner spinner;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        spinner = findViewById(R.id.spinner1);

        ArrayList<String> spinnerItems = new ArrayList<>();  // Empty <> == <String>
        spinnerItems.add("bicykel");
        spinnerItems.add("auto");
        spinnerItems.add("lod");
        spinnerItems.add("padak");
        spinnerItems.add("vlak");

        ArrayAdapter adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinnerItems );

        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        spinner.setAdapter(adapter);
        spinner.getOnItemSelectedListener();
    }

    @Override
    public void onItemSelected(AdapterView<?> adapter, View view, int position, long id)
    {
        String item = adapter.getItemAtPosition(position).toString();
        Toast.makeText( this, "Vybrali ste: " + item, Toast.LENGTH_LONG ).show();
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent)
    {
        Toast.makeText( this, "Hey nič ste nevybrali!!!", Toast.LENGTH_LONG ).show();
    }
}

here is activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

</LinearLayout>

As I see application does not work only in Andy emulator. In my phone it works well. I am little lost in it. Thanks.

I have not used Andy emulator but looking at the error message looks like something related to apk signature. Did you try installing a signed apk (if its possible on Andy emulator) ? — inventionsbyhamid, May 08 '20 at 14:34
Please refer to this : [VERIFICATION_FAILURE install fail](https://stackoverflow.com/questions/15014519/apk-installation-failed-install-failed-verification-failure) — Saumya Sinha, May 08 '20 at 19:16
Looks like the signing verification is failing. You can either go to the Andy emulator and turn off the signing verification (in settings, could be "verify apps installed over UDB") or sign the app in Android Studio before installing on Andy. — auspicious99, May 10 '20 at 02:51

Disabling the Verify Apps over USB from developer settings worked for me:

Settings > Developer Options > Then Turn off Verify Apps over USB

You might need to turn on installation from unknown sources:

Settings > Security > Then Turn on Unknown sources

Note in case the option is not available you can also run adb command:

adb shell settings put global package_verifier_enable 0

There are a few checks you can try 1st:

make sure there's enough space on your emulator (remove any apps you have installed from other projects)
make sure you don't have a version of the app with different signing certificate installed (like for example a debug version of the app installed and you trying to install the release variant of the app on top of it or vise versa)
In Android studio terminal, Type: adb shell > Type: settings put global verifier_verify_adb_installs 0 (disables Google Play Services verify apps option)

Most of the time when testing my apps in andorid emulator i run into either issue no#1 or no#2

This worked for me. I had a Launcher activity with android:exported="false" in Manifest, then I changed it to android:exported="true"
