Android Studio 无法安装应用程序 : INSTALL_FAILED_VERIFICATION_FAILURE

Question

如果我尝试在 Android Studio + Andy 模拟器中运行 Android 项目，有人可以帮我理解这个错误吗？错误提示 无法安装应用程序:INSTALL_FAILED_VERIFICATION_FAILURE .它带有一个微调器小部件的简单应用程序。
这是我的 MainActivity 文件

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();
    }
}

这是activity_main.xml

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

</LinearLayout>

这是错误日志

正如我所见，应用程序不仅仅在 Andy 模拟器中工作。在我的手机中，它运行良好。
我有点迷失其中。谢谢。

Answer 1

禁用 Verify Apps over USB从开发人员设置为我工作:

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

您可能需要打开未知来源的安装:

Settings > Security > Then Turn on Unknown sources

请注意，如果该选项不可用，您也可以运行 adb命令:

adb shell settings put global package_verifier_enable 0
