Google ドライブ API を使用して、ファイルのアップロードの進行状況をパーセントで表示したいと考えています。
私の方法は以前にファイルのアップロードに成功しましたが、アップロードの進行状況を確認できません。
この FileUploadProgressListenerを見て追加しましたが、mediaHttpUploader.getProgress()0.0 (進行の開始) と 1.0 (進行の終了時) しか表示されません。時間内に進捗率を取得できません。
それを機能させる方法は？
ここに私のアップロードコードがあります:
public void UploadFile(final DFile uploadFile) {
if (!isLoggedIn()) {
OnUploadGoogleChecked(FALSE, "Not logged in");
return;
}
AsyncTask<Void, Long, String> task = new AsyncTask<Void, Long, String>() {
java.io.File fileContent;
FileContent mediaContent;
com.google.api.services.drive.model.File body;
com.google.api.services.drive.model.File file;
private ProgressDialog mDialog;
long mFileLen;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
mDialog = new ProgressDialog(act);
mDialog.setMax(100);
mDialog.setMessage("Uploading ");
mDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mDialog.setProgress(0);
mDialog.setButton("Cancel", new OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub
}
});
mDialog.show();
}
class FileUploadProgressListener implements MediaHttpUploaderProgressListener {
@Override
public void progressChanged(MediaHttpUploader uploader) throws IOException {
Log.d("Dolphin got percent", String.valueOf(uploader.getProgress()));
switch (uploader.getUploadState()) {
case INITIATION_STARTED:
System.out.println("Initiation Started");
break;
case INITIATION_COMPLETE:
System.out.println("Initiation Completed");
break;
case MEDIA_IN_PROGRESS:
System.out.println("Upload in progress");
System.out.println("Upload percentage: " + uploader.getProgress());
break;
case MEDIA_COMPLETE:
System.out.println("Upload Completed!");
break;
case NOT_STARTED:
System.out.println("Upload Not Started!");
break;
}
}
}
@Override
protected String doInBackground(Void... arg0) {
try {
java.io.File UPLOAD_FILE = new java.io.File(uploadFile.getNameAndDir());
// File's metadata.
fileContent = new java.io.File(uploadFile.getNameAndDir());
mFileLen = fileContent.length();
InputStreamContent mediaContent2 = new InputStreamContent("image/jpeg", new BufferedInputStream(new FileInputStream(UPLOAD_FILE)));
mediaContent2.setLength(UPLOAD_FILE.length());
body = new com.google.api.services.drive.model.File();
body.setTitle(fileContent.getName());
body.setMimeType("image/jpeg");
String parentId = null;
body.setParents(Arrays.asList(new ParentReference().setId(uploadFile.getFileHostFolderId())));
Drive.Files.Insert mInsert = service.files().insert(body, mediaContent2);
MediaHttpUploader uploader = mInsert.getMediaHttpUploader();
uploader.setDirectUploadEnabled(true);
uploader.setProgressListener(new FileUploadProgressListener());
file = mInsert.execute();
if (file != null) {
}
} catch (UserRecoverableAuthIOException e) {
Log.d("Dolphin got error", "not login " + e);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String result) {
mDialog.dismiss();
OnUploadGoogleChecked(TRUE, "Upload complete");
};
};
task.execute();
}
