我在下載 android 檔案夾上有一個 .pdf，我想用顫振打開它。
我試過了：
final AndroidIntent intent = AndroidIntent(
action: 'android.os.Intent.ACTION_VIEW', //android.os.Intent.ACTION_VIEW action_view
data: Uri.encodeFull("/storage/emulated/0/Download/myfile.pdf"), // content:// file://
//type: "application/*",
flags: [
Flag.FLAG_GRANT_READ_URI_PERMISSION,
Flag.FLAG_GRANT_PERSISTABLE_URI_PERMISSION,
Flag.FLAG_ACTIVITY_NEW_TASK
]);
intent.launch();
但我收到以下錯誤：
V/IntentSender( 8997): Sending intent Intent { act=android.os.Intent.ACTION_VIEW dat=/storage/emulated/0/Download/myfile.pdf flg=0x10000041 (has extras) }

我需要額外的許可嗎？提供者？還要別的嗎？有什么建議么？謝謝 <3
