`android:exported needs to be explicitly specified for <activity>` even though I have specifie

Time:11-26

I am trying out the DJI SDK and am following this tutorial on how to integrate the SDK into the Android Studio project I have created. I've replicated everything down to the name of the files, with the only difference being that I added the needed import statements in MainActivity.java.

I get the following error when I try to build the project:

> 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'.

* 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.

I am unsure of how to fix it. One solution mentioned here was to reduce minSdk, but my minSdk attribute is already set to 19.

Any help would be much appreciated.

The codes for MApplication.java and MainActivity.java can be found in this tutorial. Here are some of the other files:

In addition to android:exported="true"

The post android:exported needs to be explicitly specified for . Apps targeting Android 12 and higher are required to specify also mention needing tools:node="merge" or possibly tools:node="replace"

See Android Documentation regarding Inspect the merged manifest and find conflicts

I also believe you need xmlns:tools="http://schemas.android.com/tools" property in your manifest XML tag as stated in merge rule markers

android:exported needs to be set for the activity with an intent filter
