カメラアプリを呼んでビデオを撮る

• AndroidManifest.xml

<manifest ... >
    <uses-feature android:name="android.hardware.camera"
                  android:required="true" />
    ...
</manifest>

• Record a video with a camera app

const val REQUEST_VIDEO_CAPTURE = 1

private fun dispatchTakeVideoIntent() {
    Intent(MediaStore.ACTION_VIDEO_CAPTURE).also { takeVideoIntent ->
        takeVideoIntent.resolveActivity(packageManager)?.also {
            startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE)
        }
    }
}

• View the video

override fun onActivityResult(requestCode: Int, resultCode: Int, intent: Intent) {
    if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK) {
        val videoUri: Uri = intent.data
        videoView.setVideoURI(videoUri)
    }
}

• Android11 では不十分。さらにAndroidManifest.xmlに追記が必要

<queries>
    <intent>
        <action android:name="android.media.action.VIDEO_CAPTURE" />
    </intent>
</queries>

• 詳しくは Managing package visibility

• 別解。このコードでもカメラアプリをビデオモードで呼べる

val takeVideoIntent = Intent(MediaStore.ACTION_VIDEO_CAPTURE)
try {
    startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE)
} catch (e: ActivityNotFoundException) {
    Toast.makeText(this, e.message, Toast.LENGTH_SHORT).show()
}
