在 Unity 中使用自定义清单文件和权限？

您正在修改错误的文件。您正在修改的内容是在每次生成项目时由 unity 生成的。AndroidManifestAndroidManifest<ProjectName>\Temp\StagingArea

要使用自定义文件，必须将自定义文件放在 。AndroidManifestAndroidManifest<ProjectName>Assets\Plugins\Android

1.转到 ，将文件复制到您的<UnityInstallationDirecory>\Editor\Data\PlaybackEngines\AndroidPlayer\ApkAndroidManifest.xml<ProjectName>Assets\Plugins\Android

2.从中打开复制的清单文件并添加清单。<ProjectName>Assets\Plugins\Android

在您的特定情况下，请添加它。保存、构建和运行。<application android:theme="Theme.Light.NoTitleBar" android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="false" android:isGame="true" android:banner="@drawable/app_banner">

Unity 现在将使用该文件。如果您遇到崩溃或任何其他问题，则Unity不希望您更改该问题。AndroidManifest

从Unity 2018开始，您应该实现该界面，该界面将允许您在Unity生成后编辑Android清单。在下面的代码中，我添加了设置麦克风权限，设置硬件加速和设置应用程序主题的方法（替换为您的首选方法，在Unity调用时调用）。IPostGenerateGradleAndroidProjectSetMicrophonePermission()OnPostGenerateGradleAndroidProject()

将以下代码添加到Assets/Editor/ModifyUnityAndroidAppManifestSample.cs

        // For example, specific configuration/app options enabled

        var androidManifest = new AndroidManifest(GetManifestPath(basePath));

        androidManifest.SetMicrophonePermission();

        // Add your XML manipulation routines

        androidManifest.Save();
