Я пытаюсь сохранить видео с VideoView на SD-карте, коснувшись VideoView. Нет ошибок в LogCat, но мой Toast, который я установил, говорит «Ошибка во время сохранения видео», в котором говорится, что моя логическая установка не попала в ту часть, где она установлена в true. Он должен находиться в части ввода-вывода файла. Одна часть, которая работает, является каталогом , делает, создается, но сам файл не найден в каталоге, он пуст.Ошибка сохранения видео Uri на SD-карту
Любые ошибки, которые кто-либо видит?
Я отправлю свои два основных метода, которые важны, затем ниже я выведу весь класс.
UPDATE: Вот мой рабочий код (изменил пару строк в методе saveVideo.)
// save your video to SD card
protected void saveVideo(final Uri uriVideo){
// click the video to save it
mVideoView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
boolean success = false;
// make the directory
File vidDir = new File(android.os.Environment.getExternalStoragePublicDirectory
(Environment.DIRECTORY_MOVIES) + File.separator + "Saved iCute Videos");
vidDir.mkdirs();
// create unique identifier
Random generator = new Random();
int n = 100;
n = generator.nextInt(n);
// create file name
String videoName = "Video_" + n + ".mp4";
File fileVideo = new File(vidDir.getAbsolutePath(), videoName);
try {
fileVideo.createNewFile();
success = true;
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Video saved!",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during video saving", Toast.LENGTH_LONG).show();
}
return true;
}
});
}
Мой старый, unworking saveVideo() метод.
// save your video to SD card
protected void saveVideo(final Uri uriVideo){
// click the video to save it
mVideoView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
String sourceVideoName = uriVideo.getPath();
boolean success = false;
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
// make the directory
File vidDir = new File(android.os.Environment.getExternalStoragePublicDirectory
(Environment.DIRECTORY_MOVIES) + File.separator + "Saved iCute Videos");
vidDir.mkdirs();
// create unique identifier
Random generator = new Random();
int n = 100;
n = generator.nextInt(n);
// create file name
String videoName = "Video_" + n + ".mp4";
fileVideo = new File(vidDir.getPath(), videoName);
try {
bis = new BufferedInputStream(new FileInputStream(sourceVideoName));
bos = new BufferedOutputStream(new FileOutputStream(fileVideo, false));
byte[] buf = new byte[8192];
bis.read(buf);
do {
bos.write(buf);
} while (bis.read(buf) != 0);
success = true;
} catch (IOException e) {
}finally {
try {
if (bis != null) bis.close();
if (bos != null) bos.close();
} catch (IOException e) {
}
}
if (success) {
Toast.makeText(getApplicationContext(), "Video saved!",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during video saving", Toast.LENGTH_LONG).show();
}
return true;
}
});
}
Мой dispatchTakeVideoIntent() метод. Я прокомментировал какой-то код, который может понадобиться ... Я продолжал получать нулевой указатель, хотя на линии fileUri (это было от fileUri или fileVideo?), Поэтому не знаю почему.
// Captures video from Android camera component
protected void dispatchTakeVideoIntent() {
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
// // set name of video
// Uri fileUri = Uri.fromFile(fileVideo);
// takeVideoIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// set the video image quality to high
takeVideoIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(takeVideoIntent, ACTION_TAKE_VIDEO);
}
}

Вы пробовали положить сохраненную часть в обработчик? –
Вероятно, получение Exception.try для печати Исключение в блоках catch. затем опубликуйте журнал ошибок с вопросом –
fileVideo = новый файл (vidDir.getAbsolutePath(), videoName); fileVideo.createNewFile(); и разрешение WRITE в манифесте. –
