Android O (api 26)에서 파일을 여는 중 일부 문제가 있습니다.Android에서 파일 열기 O가 작동하지 않지만 api에서 성공 25
성공적으로 다운로드 한 후 알림을 탭하면 아무 것도 나타나지 않습니다 (알림이 삭제됨). 그러나 api 25에서 동일한 작업을 수행하면 파일이 열리고 작동합니다.
디버깅 API에 대한 (26)
내가 뭔가를 바라나요 항상 방법 canOpenFile을 지적 false를 반환? 많은 도움을 주시면 감사하겠습니다.
알림 코드 : 의도 Openfile
public void finishedNotification(int id, String appName, String urlPath, boolean success) {

.setWhen(System.currentTimeMillis())
.setColor(mApplication_.getInstance().getResources().getColor(R.color.apps_color))
.setLargeIcon(BitmapFactory.decodeResource(mApplication_.getInstance().getResources(), R.mipmap.ic_launcher))
.setOngoing(false)
.setPriority(Notification.PRIORITY_HIGH)
.setAutoCancel(true);
if (success) {
if (canOpenFile(urlPath)) { // ALWAYS false on API26??
PendingIntent openFile = PendingIntent.getActivity(getApplicationContext(),
ACTION_OPEN_FILE.hashCode() + id,
openFile(urlPath),
PendingIntent.FLAG_CANCEL_CURRENT);
notification.setContentIntent(openFile);
