Using Google Drive to backup and restore SQLite Database

I've managed to create a backup of my database on an SD card and restore from there but realized that the purpose of my backup is to ensure the safety of the data and in this case if the physical device itself is damaged, lost, or spontaneously combusts so will the backup on the SD card. So having the backup in the same place as the original in this case, quite frankly defeats the purpose of having a backup.
So I thought of using Google Drive as a safer place to keep the db file, that and it's free. I've taken a peek into Google's quickstart demo which I got working just fine. But I still have no idea how to get this done for my case.
I've found some code to fiddle with but it's still using some deprecated methods and so far I've only managed to run it when omitting the deprecated area but it only creates a blank binary file in my Google Drive so I think that deprecated area is where it actually uploads the DB backup content. If anyone could help out that would be greatly appreciated.
I'll leave it down below in case anyone can use it to explain things to me better. I've also marked the deprecated method below, it's near the end.

Both APIs used to access Google Drive deal with a binary content. So the only thing you have to do is to upload your binary DB file, give it a proper MIME type and a NAME (title).
The selection of API depends on you, GDAA behaves like a 'local' entity with uploads / downloads handled by Google Play Services, REST Api is more low-level, giving you more control, but you have to take care of networking issues (wifi on/off, etc), i.e. you usually have to build a sync service to do so. With GDAA it is done for you by GooPlaySvcs. But I digress.
I can point you to this GitHub demo, fairly recent (GooPlaySvcs 7.00.+), I use to test different REST / GDAA issues.
The MainActivity is a bit complicated by the fact that it allows for switching between different Google accounts, but if you get through these hurdles, you can use either REST or GDAA CRUD wrappers.
Take look at this line. The byte[] buffer contains binary JPEG data and it goes with "image/jpeg" mime type (and a time-based name). The only thing you have to do if is load your DB file into a byte[] buffer using a construct like this:
private static final int BUF_SZ = 4096;
static byte[] file2Bytes(File file) {
if (file != null) try {
return is2Bytes(new FileInputStream(file));
} catch (Exception ignore) {}
return null;
}
static byte[] is2Bytes(InputStream is) {
byte[] buf = null;
BufferedInputStream bufIS = null;
if (is != null) try {
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
bufIS = new BufferedInputStream(is);
buf = new byte[BUF_SZ];
int cnt;
while ((cnt = bufIS.read(buf)) >= 0) {
byteBuffer.write(buf, 0, cnt);
}
buf = byteBuffer.size() > 0 ? byteBuffer.toByteArray() : null;
} catch (Exception e) {le(e);}
finally {
try {
if (bufIS != null) bufIS.close();
} catch (Exception e) {le(e);}
}
return buf;
}
I don't remember the MIME type for SQLite DB now, but I am sure it can be done since I was doing exactly that once (the code is gone now, unfortunately). And I remember I could actually access and modify the SQLite DB 'up in the cloud' using some web app.
Good Luck
UPDATE:
After I wrote the rant above I looked at the demo you're talking about. If you have it working, the easiest way is actually to plug your DB file right here, set the correct MIME and you're good to go. Take you pick.
And to address your 'deprecated' issue. GDAA is still being developed and the quickstart is over a year old. That's the world we live in :-)

You need to replace the deprecated code with:
contents.commit(api, null);

Create folder in using dropbox api for android

Does anyone know how to create folder programatically using dropbox api for android??I am not using sync api.I have managed to upload images and files but I am unable to create folder.
This is my upload asynctask:

According to dropbox documentation
try {
// creating folder
val fo = client.files().createFolderV2(File.separator + folderPath)
} catch (ex: CreateFolderErrorException) {
if (ex.errorValue.isPath && ex.errorValue.pathValue.isConflict) {
// folder already exist
}
}

You can simply give like this for creating a folder! its very simple
dropbox.putFile("Mynumber2/myregion2/"+"/"+"A"+"/"+"B"+"/"+"ENTRY.db", fileInputStream,file.length(), null, null);
if you do, mynumber2-->myregion2-->A-->B will be your folder structure created on dropbox!

You want the createFolder method of DropboxAPI. See https://www.dropbox.com/static/developers/dropbox-android-sdk-1.6.1-docs/com/dropbox/client2/DropboxAPI.html#createFolder(java.lang.String).

Use the following for DIR:
"/your_folder_name/"

How to replace file in Google Drive?

We can use the Google Drive API to:
- Find the existing file
- Get its ID
- Delete the file
- Write a new file

I open the drive file for writing as follows:
writeDriveFile(DriveFile file, Handler handler){
//see query task below to get a drive file by its name. Be careful you can get multiple data elements in the MetadataBuffer below if you have uploaded multiple files with the same name.
Task<DriveContents> openFileTask = myDriveResourceClient.openFile(file, DriveFile.MODE_WRITE_ONLY);
Then with that task write some object bytes to the stream someObject.getBytes(), no magic here. Then commit the results.
openFileTask
.continueWithTask(task -> {
DriveContents contents = task.getResult();
// Process contents...
try (OutputStream writer = contents.getOutputStream()) {
writer.write(someObject.getBytes());
writer.close();
}
//Add whatever metadata you want here
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setLastViewedByMeDate(new Date())
.build();
//commit the file to Google Drive
Task<Void> commitTask = myDriveResourceClient.commitContents(contents, changeSet);
handler.onWriteResults();
return commitTask;
})
.addOnFailureListener(e -> {
// Handle failure
Log.e(TAG, "Unable to read contents", e);
handler.onDriveError(e);
});
The handler is just an interface I defined for errors or results that I want to process after Drive API execution. You could also add an addOnCompleteListener() to process something once the writing was complete.
file is an instance of DriveFile that can be acquired by a query task. The metadata that come to you in the task code block has a getDriveId() method which has a asDrivefFile() method to get the Drive file you need above.
Query query = new Query.Builder()
.addFilter(Filters.eq(SearchableField.TITLE, "file name"))
.build();
Task<MetadataBuffer> queryTask = mDriveResourceClient.query(query);
Then process the MetadataBuffer
queryTask.continueWithTask(
task -> {
MetadataBuffer metadataBuffer = task.getResult() ;
//I have this loop because I wanted to know if there were other versions of the file on the drive
for(Metadata data : metadataBuffer) {
Log.d(TAG, "******************* metadataBuffer title is " + data.getTitle());
if(data.getTitle().equals("file name")){
//this is just a method I defined that encapsulates the drive writing code above.
writeDriveFile(data.getDriveId().asDriveFile(), jsonContent, handler);
}
}
return task;
})
.addOnCompleteListener(task -> {
//some complete tasks
}
})
.addOnFailureListener(e -> {
Log.e(TAG, "************************** Error searching for " + fileName, e);
handler.onDriveError(e);
});
This code was all for writing to the App folder but you just need to set the right scope when you create you resource client.
Deleting a drive file can be done as follows.
public void deleteDriveFile(DriveResource file){
Task<Void> deleteTask = mDriveResourceClient.delete(file);
deleteTask
.continueWith(task -> {
Log.d(TAG, "************* Deleted drive file: " + file.getDriveId().toInvariantString());
return task;
})
.addOnFailureListener(e -> {
//log some sort of error for yourself
});
}

ProgressDialog is not showing when .3gp file converting to a .zip

I am working on Android app.
I need to show a progress dialog box when I click on button.
In that button I am converting video file to .zip file and calculating that file size.
In this process I need to show a ProgressDialog, but it is not showing.
Screen get struck while calculating and after calculation it shows ProgressDialog and then screen navigating to the next screen.
My Code:
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MediaCheck.this.runOnUiThread(new Runnable() {
public void run() {
pd = ProgressDialog.show(MediaCheck.this, "",
"Checking the video compatability. Please wait", true);
}
});
video_Path= makeZip(video_Path);
if (video_Path.equalsIgnoreCase("File size is too large")) {
pd.dismiss();
Toast.makeText(getApplicationContext(),
"Large video", Toast.LENGTH_LONG)
.show();
return;
}
pd.dismiss();
// Doing screen navigation here.
}
});
Code to make a zip and know the size
private static String makeZip(String videoPath) {
byte[] buffer = new byte[1024];
String[] videoFileName = videoPath.split("/");
File directory = null;
try {
ContextWrapper cw = new ContextWrapper(context_this);
// path to /data/data/yourapp/app_data/imageDir
directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
FileOutputStream fos = new FileOutputStream(directory
+ "/IRCMS_Video.zip");
ZipOutputStream zos = new ZipOutputStream(fos);
ZipEntry ze = null;
ze = new ZipEntry(videoFileName[5]);
zos.putNextEntry(ze);
FileInputStream in = new FileInputStream(videoPath);
int len;
while ((len = in.read(buffer)) > 0) {
zos.write(buffer, 0, len);
}
File videoZip = new File(directory + "/IRCMS_Video.zip");
videoLength = videoZip.length() / (1024 * 1024);
if (videoLength > 3)
return "File size is too large";
in.close();
zos.closeEntry();
// remember close it
zos.close();
System.out.println("Done");
} catch (IOException ex) {
ex.printStackTrace();
}
return directory.toString() + "/IRCMS_Video.zip";
}
}
Please help...

then you should try ASYNCTASK to easily perform your operation and reduce the complexity of using threads
private class Converter extends AsyncTask<String, Void, Void> { //Converter is class name
protected String doInBackground(String... urls) {
//THIS METHOD WILL BE CALLED AFTER ONPREEXECUTE
//YOUR NETWORK OPERATION HERE
return null;
}
protected void onPreExecute() {
super.onPreExecute();
//THIS METHOD WILL BE CALLED FIRST
//DO OPERATION LIKE SHOWING PROGRESS DIALOG PRIOR TO BEGIN NETWORK OPERATION
}
protected void onPostExecute(String result) {
super.onPostExecute();
//TNIS METHOD WILL BE CALLED AT LAST AFTER DOINBACKGROUND
//DO OPERATION LIKE UPDATING UI HERE
}
}

You are doing calculation on UI thread therfore it hangs your app. Do calculation on background thread. You can resolve this by-
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pd = ProgressDialog.show(MediaCheck.this, "",
"Checking the video compatability. Please wait", true);
Thread background = new Thread(new Runnable() {
public void run() {
// TODO Auto-generated method stub
video_Path= makeZip(video_Path);
MediaCheck.this.runOnUiThread(new Runnable()
{
public void run()
{
if (video_Path.equalsIgnoreCase("File size is too large")) {
pd.dismiss();
Toast.makeText(getApplicationContext(),
"Large video", Toast.LENGTH_LONG)
.show();
pd.dismiss();
return;
}
}
});
}
});
background.start();
// Doing screen navigation here.
}
});

Resumable YouTube uploads with YouTube Data API v3 in Android

I'm uploading videos to my YouTube account from my Android application using YouTube Data API v3. Uploading process works perfectly. What I need is, if my upload got interrupted (eg. because of Internet connection) I need to start upload next time where it left.
private void uploadVideo(UploadInfo videoInfo) {

status.setPrivacyStatus("public");
videoObjectDefiningMetadata.setStatus(status);
VideoSnippet snippet = new VideoSnippet();
snippet.setTitle(videoFile.getName());
snippet.setDescription("Uploaded via AnujAroshA Android app");
List<String> tags = new ArrayList<String>();
tags.add("AnujAroshA");
snippet.setTags(tags);
videoObjectDefiningMetadata.setSnippet(snippet);
InputStreamContent mediaContent = new InputStreamContent(VIDEO_FILE_FORMAT, new BufferedInputStream(new FileInputStream(videoFile)));

Have you seen this question?
The answer suggests that you should use;
youtube = new YouTube.Builder(HTTP_TRANSPORT, JSON_FACTORY, new HttpRequestInitializer() {
#Override
public void initialize(HttpRequest request) throws IOException {
credential.initialize(request);
request.setIOExceptionHandler(new HttpBackOffIOExceptionHandler(new ExponentialBackOff()));
}
});
when you initialise your YouTube object.
