Manifest合并失败，出现多个错误|需要Android 12及更高版本才能为“android：导出”指定显式值

Question

我是爪哇和机器人的新手。在运行模拟器时，我面临着合并冲突问题。

完整的错误消息:

执行任务失败：process DefaultsDebugMainManifest。

清单合并失败，出现多个错误，请参阅日志

错误：需要为元素显式指定android:exported

此处为AndroidManifest.xml

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

    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<application

    android:networkSecurityConfig="@xml/network_security_config"
    android:name=".AdApplication"
    android:allowBackup="false"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"

    android:theme="@style/AppTheme"
    tools:ignore="GoogleAppIndexingWarning">
    <activity
        android:name=".AdListActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
    <activity
        android:name=".AdDetailActivity"
        android:label="@string/title_ad_detail"
        android:parentActivityName=".AdListActivity"
        android:theme="@style/AppTheme.NoActionBar">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.iab.omid.sampleapp.AdListActivity"/>
    </activity>
</application>

我已经尝试了StackOverflow上的许多其他解决方案，但仍然没有取得任何进展。

请在评论中告诉我是否需要分享更多细节来解决这个问题。

Answer 1

您的库可能正在对活动定义“intent_filter”

debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.5.4'
releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.4'

如果您的应用程序面向API 31，属性“exported”是必需的。

因此，由于该库的开发人员没有针对API 31，因此导出的标志对他来说不是强制性的。他构建它时没有导出属性。

所以你能做的，就是在你的清单上重新定义那个特定的类，来声明它是否被显式导出。例如:

<activity android:name="com.squareup.leakcanary.internal.DisplayLeakActivity"
         android:exported="true"/>
