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，有人可以帮助我理解这个错误吗？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();
    }
}

这里是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

从开发者设置中禁用Verify Apps over USB 对我有用：

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

您可能需要开启未知来源的安装：

Settings > Security > Then Turn on Unknown sources

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

Answer 2

您可以尝试以下几项检查：

1. 确保您的模拟器上有足够的空间（从其他项目中删除您已安装的所有应用）
2. 确保您没有安装具有不同签名证书的应用程序版本（例如，安装了应用程序的调试版本并且您尝试在其上安装应用程序的发布变体，反之亦然）
3. 在 Android Studio 终端中，输入：adb shell > 输入：settings put global verifier_verify_adb_installs 0（禁用 Google Play Services 验证应用选项）

在 andorid 模拟器中测试我的应用程序时，大多数时候我都会遇到问题 no#1 或 no#2

Answer 3

这对我有用。我在 Manifest 中有一个带有 android:exported="false" 的 Launcher 活动，然后我将其更改为 android:exported="true"
