i have made an application that gives user option to upload and download dropbox application. i am giving my app secret and app key. the question is when some one else use my application do they need to enter their app secret and app key?
if yes, why? and if no then whats the actual purpose of app secret and app key. i am sharing the code as well:

this is the code for reference, please have a look and give some suggestion.my main task is to retrieve a file, encrypt and upload it on dropbox.
No, users don't have to enter a different app key and secret. The app key and secret identifies your app. For example, when a user authorizes your app, they see the name of the app they're authorizing. That comes from the app key.

I am uploading a file in the dropbox using dropbox api in android. I have successfully uploaded file in the dropbox but problem is that each time i need to allow the access of dropbox. Each time i have to go to the browser and allow the access.
I dont know how to solve this issue.
I have used these codes to upload files in dropbox:

Could anyone tell me how to solve this issue??
In order to avoid having to authorize the app to connect to the user's Dropbox account manually each time (i.e., calling startAuthentication), the app should store and re-use the resulting access token, so that this only needs to be done once.
It seems you already have code to do this in buildSession, using storeKeys and getKeys, which use SharedPreferences to persist the access token.
So, you just need to know if the AndroidAuthSession already has an access token loaded. You can use the AndroidAuthSession.isLinked method for this:
https://www.dropboxstatic.com/static/developers/dropbox-android-sdk-1.6.3-docs/com/dropbox/client2/session/AbstractSession.html#isLinked()
Call that before calling startAuthentication so you can know if you already have an access token.
I need to to integrate both Facebook and Google Plus in the same activity but I'm not getting success in it. I have tried both in individual projects and they work fine but when I add both projects together my app gets crashed. Even I have tried them with custom buttons too but they don't work either.
Currently my Facebook part is working fine but I get error when I click on Google's button at the time of login. I get error in these methods:
private void resolveSignInError() {
if (mConnectionResult.hasResolution()) {
try {
mIntentInProgress = true;
mConnectionResult.startResolutionForResult(this, RC_SIGN_IN);
} catch (SendIntentException e) {
mIntentInProgress = false;
mGoogleApiClient.connect();
}
}
}
and
private void signInWithGplus() {

It would be great if anybody helps me in it.
Thanks.
I've solved my problem myself yesterday by adding few lines in onClick part
if (mGoogleApiClient.isConnected()) {
getProfileInformation();
} else {
signInWithGplus();
getProfileInformation();
}
}
It appears that if you call signInWithGplus() the first time, it'll try to access mConnectionResult which is null at that point.
The reason for that is because you're only setting it in onConnectionFailed() which would have not been called.

Need to modify UploadPicture class:
Extract field from this variable:
String path = mPath + mFile.getName();
Put this snippet into onPostExecute method in upload successful case:
DropboxAPI.Entry filesInPath = mApi.metadata(path, 1, null, true, null);
// Basing on provided code, only one file is uploaded
DropboxAPI.Entry uploadedFile = entries.contents.get(0);
String shareUrl = mApi.share(uploadedFile.path).url;
After this manipulations shareUrl variable will contain sharing link for the image.
I think you're looking for share.

I'm making a module that can download all file from apps folder on dropbox to devices.
Now, I'm using Core API to download a file. Everything works fine. But with multiple file, I don't know when the current file finish download to go to the next file.
Here is my download code:
final String cachePath = FileHandler.ROOT_LOCAL_FOLDER_DIR + "/" + mFile.getFileName();
try {
mFos = new FileOutputStream(cachePath);
} catch (FileNotFoundException e) {
mErrorMsg = "Couldn't create a local file to store the image";
return false;
}
ProgressListener mProgressLisenter = new ProgressListener() {
#Override
public void onProgress(long arg0, long arg1) {
// TODO Auto-generated method stub
tmpFile = new File(cachePath);
OnDownloadProgressDropboxChecked(FileHandler.PROGRESS_STATUS_ONPROGRESS, (int) (arg0 * 100 / arg1));
}
#Override
public long progressInterval() {
return 100;
}
};
mDownloaded = mApi.getFile(mFile.getFileId(), null, mFos, mProgressLisenter);
OnDownloadDropboxChecked(TRUE, "Download complete");
} catch (DropboxUnlinkedException e) {
mErrorMsg = "Unlinked";
} catch (DropboxPartialFileException e) {
// We canceled the operation
mErrorMsg = "Download canceled";
} catch (DropboxServerException e) {
}
}
I've tried:
Catch progress download, when reached 100% then notify - On this way, the OnProgress of dropbox isn't show up imediately and sometime It not reach 100%
Put It in a asynctask - Useless
I'm out of idea now, any advance are good for me.
Edited:
the solution is put some trigger under getFile() then It work.

The error caused by 'OnDownloadDropboxChecked()' of Asynctask fired before the one of getFile(). So It return a false notify.
Converting my comment to an answer:
If I'm reading this right, you're using the Android Core API SDK, right? If so, I think that when mApi.getFile returns, the file has been downloaded. So you can do whatever you need to do on the next line.
