对我来说，添加android：exported= "true"并不能解决问题

Question

看到此问题应用程序未安装错误，从主屏幕启动时快捷方式

AndroidManifest.xml:

<application
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.AppTheme">
<activity
android:name=".ui.activity.MainActivity"
android:screenOrientation="fullSensor"
android:label="@string/app_name"
android:exported="true"
android:configChanges="orientation|screenSize">
<intent-filter
>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter
>
<action android:name="android.intent.action.VIEW"/>
<data android:scheme="app" android:host="appname"
/>
<category android:name="android.intent.category.BROWSABLE"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
<nav-graph android:value="@navigation/nav_graph_main"
/>
</activity>
</application>

Gradle [App]:

defaultConfig {
applicationId "com.example.app"
minSdkVersion 19
targetSdkVersion 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}

我得到这个错误:

> Task :app:processDebugMainManifest FAILED
/home/mhrohani/IdeaProjects/PrjName/app/src/main/AndroidManifest.xml Error:

Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported` when the corresponding component has an intent filter defined.

Execution failed for task ':app:processDebugMainManifest'.

Project和android studio配置:

Gradle :                 ** 7.1.1 **  
Android Gradle Plugin :  ** 7.0.0 **  
Android Studio Version : ** Arctic fox 2020.3.1 **  
OS :                     ** Linux Ubuntu **

我尝试重建和同步项目，但不工作。

请注意错误文本

android:exported需要为receiver明确指定

这意味着你必须寻找receiver在main/dependencies manifest中，如果你在main manifest中发现这个标签，你必须添加android:exported的值。如果你在主清单中找不到接收器标签，那么你应该在其他依赖项清单中搜索，我会一步一步地向你展示

1-打开Android Studio的manifest文件

2-在底部点击合并清单

3-按顺序打开所有依赖项清单，查找不包含android:exported

4-我相信这个标签会被发现，找到它后，只是复制整个标签，并将其添加到主清单中，不要忘记添加android:导出的值它

的例子:

接收机标记在依赖项清单文件中:

<receiver
android:name="com.moduletop.push.UserPresentBroadcastReceiver"
android:enabled="false" >
<intent-filter>
<action android:name="android.intent.action.USER_PRESENT" />
</intent-filter>
</receiver>

在主清单中添加这个标签:

<receiver
tools:node="merge"
android:exported="false"
android:name="com.moduletop.push.UserPresentBroadcastReceiver"
android:enabled="false" >
<intent-filter>
<action android:name="android.intent.action.USER_PRESENT" />
</intent-filter>
</receiver>
