当我将手机更新到 Android 12 时，安装失败。无法安装应用程序：INSTALL_PARSE_FAILED_MANIFEST_MALFORMED

Question

自从我将手机更新到 Android 12 以来，我一直在完美地处理我的项目，不幸的是，当我在手机上运行该项目时，会出现此错误：

安装失败。 无法安装应用程序：INSTALL_PARSE_FAILED_MANIFEST_MALFORMED

apk 列表： [0] 'C:\Users\Microsoft\AndroidStudioProjects\YmmyServer\app\build\outputs\apk\debug\app-debug.apk' 安装失败，原因是：“null” 重试

这是我的 build.gradle(Project) 文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.google.gms:google-services:4.3.10'
        classpath 'com.android.tools.build:gradle:4.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是我的 build.gradle(Module) 文件：

plugins {
    id 'com.android.application'
}

android {
    compileSdkVersion 32
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.ymmyserver"
        minSdkVersion 30
        targetSdkVersion 32

        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
apply plugin: 'com.android.application'

dependencies {

}

这是 Mainifest 文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.ymmyserver">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.Ymmy">
        <activity android:name=".FoodList"></activity>
        <activity
            android:name=".Home"
            android:label="@string/title_activity_home"
            android:theme="@style/Theme.Ymmy.NoActionBar"></activity>
        <activity android:name=".SignIn" />
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

我应该做什么，请帮助我

Answer 1

尝试在 Activity 的 AndroidManifest.xml 文件中使用此标记

<activity 
   android:name=".MainActivity"
   android:exported="true">

Answer 2

通过在 Mainifest 文件中的主 Activity 上添加 android:exported="true" 来解决：

<activity android:name=".MainActivity"
        android:exported="true">
