我正在試用 DJI SDK，并正在關注本教程，了解如何將 SDK 集成到我創建的 Android Studio 專案中。我已經將所有內容復制到檔案名，唯一的區別是我在MainActivity.java.
嘗試構建專案時出現以下錯誤：
> Task :app:processDebugMainManifest FAILED
[path to projects]\AndroidStudioProjects\ImportSDKDemo\app\src\main\AndroidManifest.xml Error:
android:exported needs to be explicitly specified for <activity>. 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. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.
Execution failed for task ':app:processDebugMainManifest'.
> Manifest merger failed : android:exported needs to be explicitly specified for <activity>. 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.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
我不確定如何解決它。這里提到的一種解決方案是 reduce minSdk，但我的minSdk屬性已經設定為 19。
任何幫助將非常感激。
可以在本教程中找到MApplication.java和的代碼。以下是其他一些檔案：MainActivity.java

此外 android:exported="true"
后android:exported 需要明確指定。面向 Android 12 及更高版本的應用還需要說明需要tools:node="merge"或可能tools:node="replace"
請參閱有關檢查合并清單并查找沖突的Android 檔案
我也相信您xmlns:tools="http://schemas.android.com/tools"的manifestXML 標記中需要屬性，如合并規則標記中所述
uj5u.com熱心網友回復：
android:exported 需要使用意圖過濾器為活動設定
