Flutter应用程序在Android 12中不起作用。给我错误install_parse_failed_manifest_malformed

Question

Flutter App在Android 12中没有工作。我尝试了各种事情，例如添加exported =“ true”，但我仍然无法在Android 12上运行该应用。

错误：错误：

adb: failed to install D: \Flutter BLE May 2022\ SW_Mobile_Platform\ build\ app\ outputs\ flutter - apk\ app.apk: Failure[INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app / vmdl1121899374.tmp / base.apk(at Binary XML file line #184): org.altbeacon.beacon.startup.StartupBroadcastReceiver: Targeting S+ (version 31 and above) requires that an explicit value for
android:exported be defined when intent filters are present]

这是我的清单文件：

转到AndroidManifest文件（your_project_folder-＆gt; android-＆gt; src-＆gt; src-＆gt; main--＆gt; androidmanifest.xml）：

只需添加android：exported = exported =“ exported =” true code>“ true”“ true” 。检查以下内容：

<activity
            android:name=".MainActivity"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:exported="true" //Just add this to your manifest
            android:hardwareAccelerated="true"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:windowSoftInputMode="adjustResize">
            <!-- Specifies an Android theme to apply to this Activity as soon as
                 the Android process has started. This theme is visible to the user
                 while the Flutter UI initializes. After that, this theme continues
                 to determine the Window background behind the Flutter UI. -->
            <meta-data
                android:name="io.flutter.embedding.android.NormalTheme"
                android:resource="@style/NormalTheme" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
