Download software to Google Drive programmatically (Android API)

Question

I followed the Drive API guide ( https://developer.android.com/google/play-services/drive.html ) and my application now smoothly downloads photos, but now I am trying to download video (mp4) without success.

Does anyone know how to achieve this? Video is the newly created mp4 file, and I have a way to where it is stored on the device.

For images made as follows:

Drive.DriveApi.newDriveContents(mDriveClient).setResultCallback( new ResultCallback<DriveContentsResult>() { @Override public void onResult(DriveContentsResult result) { if (!result.getStatus().isSuccess()) { Log.i(TAG, "Failed to create new contents."); return; } OutputStream outputStream = result.getDriveContents().getOutputStream(); // Write the bitmap data from it. ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream(); image.compress(Bitmap.CompressFormat.JPEG, 80, bitmapStream); try { outputStream.write(bitmapStream.toByteArray()); } catch (IOException e1) { Log.i(TAG, "Unable to write file contents."); } image.recycle(); outputStream = null; String title = Shared.getOutputMediaFile(Shared.MEDIA_TYPE_IMAGE).getName(); MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder() .setMimeType("image/jpeg").setTitle(title) .build(); Log.i(TAG, "Creating new pic on Drive (" + title + ")"); Drive.DriveApi.getFolder(mDriveClient, mPicFolderDriveId).createFile(mDriveClient, metadataChangeSet, result.getDriveContents()); } }); } 

I am interested in an alternative to the file, in this case pointing to "video / mp4".

Answer 1

Without going into details, just a few pointers:

Everything you want to download (image, text, video, ...) consists of

• file creation
• installation metadata (name, MIME type, description, ...)
• content customization (byte stream)

The demo you mentioned does this with an image (JPEG bytestream), and you need to do it with the video. So, the changes you need to implement are as follows:

• replace the MIME type "image / jpeg" with the one you need for your video
• copy your video stream (outputStream.write (bitmapStream.toByteArray ()) ...)

to the content.

These are the only changes you need to make. The Google Drive API for Android doesn't care about what your content and metadata are, it just captures it in Google Drive.

In Google Drive, applications (web, android, ...) read metadata and content and process them accordingly.

If you want to upload any file to Google Drive, use the code below with the synchronization task, it will upload your file to Drive.

 AsyncTask<Void, Void, String> task = new AsyncTask<Void, Void, String>() { @Override protected String doInBackground(Void... params) { String file_type="video/mp4"; //write your file type File body = new File(); File FileRtr = null; body.setTitle(myfile.getName()); body.setMimeType(file_type); body.setParents(Arrays.asList(new ParentReference().setId(LocationID))); //LocationID means the path in the drive e where you want to upload it try { FileContent mediaContent = new FileContent(file_type, myfile); FileRtr = mService.files().insert(body, mediaContent).execute(); if ( FileRtr != null) { System.out.println("File uploaded: " + FileRtr.getTitle()); } } catch (IOException e) { System.out.println("An error occurred: " + e.getMessage()); } return null; } protected void onPostExecute(String token) { Toast.makeText(mContext, "Uploaded Successfuly",Toast.LENGTH_LONG).show(); } }; task.execute();

Solution by OP.

Thanks to seanpj, it turns out I overestimated the complexity of this, now I use this method to upload images and videos:

 /** * Create a new file and save it to Drive. */ private void saveFiletoDrive(final File file, final String mime) { // Start by creating a new contents, and setting a callback. Drive.DriveApi.newDriveContents(mDriveClient).setResultCallback( new ResultCallback<DriveContentsResult>() { @Override public void onResult(DriveContentsResult result) { // If the operation was not successful, we cannot do // anything // and must // fail. if (!result.getStatus().isSuccess()) { Log.i(TAG, "Failed to create new contents."); return; } Log.i(TAG, "Connection successful, creating new contents..."); // Otherwise, we can write our data to the new contents. // Get an output stream for the contents. OutputStream outputStream = result.getDriveContents() .getOutputStream(); FileInputStream fis; try { fis = new FileInputStream(file.getPath()); ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buf = new byte[1024]; int n; while (-1 != (n = fis.read(buf))) baos.write(buf, 0, n); byte[] photoBytes = baos.toByteArray(); outputStream.write(photoBytes); outputStream.close(); outputStream = null; fis.close(); fis = null; } catch (FileNotFoundException e) { Log.w(TAG, "FileNotFoundException: " + e.getMessage()); } catch (IOException e1) { Log.w(TAG, "Unable to write file contents." + e1.getMessage()); } String title = file.getName(); MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder() .setMimeType(mime).setTitle(title).build(); if (mime.equals(MIME_PHOTO)) { if (VERBOSE) Log.i(TAG, "Creating new photo on Drive (" + title + ")"); Drive.DriveApi.getFolder(mDriveClient, mPicFolderDriveId).createFile(mDriveClient, metadataChangeSet, result.getDriveContents()); } else if (mime.equals(MIME_VIDEO)) { Log.i(TAG, "Creating new video on Drive (" + title + ")"); Drive.DriveApi.getFolder(mDriveClient, mVidFolderDriveId).createFile(mDriveClient, metadataChangeSet, result.getDriveContents()); } if (file.delete()) { if (VERBOSE) Log.d(TAG, "Deleted " + file.getName() + " from sdcard"); } else { Log.w(TAG, "Failed to delete " + file.getName() + " from sdcard"); } } }); }

  private void saveFiletoDrive(final File file, final String mime) { Drive.DriveApi.newDriveContents(mGoogleApiClient).setResultCallback( new ResultCallback<DriveContentsResult>() { @Override public void onResult(DriveContentsResult result) { if (!result.getStatus().isSuccess()) { Log.i(TAG, "Failed to create new contents."); return; } Log.i(TAG, "Connection successful, creating new contents..."); OutputStream outputStream = result.getDriveContents() .getOutputStream(); FileInputStream fis; try { fis = new FileInputStream(file.getPath()); ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buf = new byte[1024]; int n; while (-1 != (n = fis.read(buf))) baos.write(buf, 0, n); byte[] photoBytes = baos.toByteArray(); outputStream.write(photoBytes); outputStream.close(); outputStream = null; fis.close(); fis = null; } catch (FileNotFoundException e) { Log.w(TAG, "FileNotFoundException: " + e.getMessage()); } catch (IOException e1) { Log.w(TAG, "Unable to write file contents." + e1.getMessage()); } String title = file.getName(); MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder() .setMimeType(mime).setTitle(title).build(); if (mime.equals(MIME_PHOTO)) { if (VERBOSE) Log.i(TAG, "Creating new photo on Drive (" + title + ")"); Drive.DriveApi.getFolder(mGoogleApiClient, mPicFolderDriveId).createFile(mGoogleApiClient, metadataChangeSet, result.getDriveContents()); } else if (mime.equals(MIME_VIDEO)) { Log.i(TAG, "Creating new video on Drive (" + title + ")"); Drive.DriveApi.getFolder(mGoogleApiClient, mVidFolderDriveId).createFile(mGoogleApiClient, metadataChangeSet, result.getDriveContents()); } if (file.delete()) { if (VERBOSE) Log.d(TAG, "Deleted " + file.getName() + " from sdcard"); } else { Log.w(TAG, "Failed to `enter code here`delete " + file.getName() + " from sdcard"); } } }); }

So, this is my complete code, how I got the video uploaded. Steps:

• Extract video file from uri (as in my case).
• Get an array of bytes from the bytearray output stream as indicated in the code
• write an array of bytes to ouputStream
• api will download the file in the background

public class UploadVideo extends AppCompatActivity {

 DriveClient mDriveClient; DriveResourceClient mDriveResourceClient; GoogleSignInAccount googleSignInAccount; String TAG = "Drive"; private final int REQUEST_CODE_CREATOR = 2013; Task<DriveContents> createContentsTask; String uri; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_upload_video); //Fetching uri or path from previous activity. uri = getIntent().getStringExtra("uriVideo"); //Get previously signed in account. googleSignInAccount = GoogleSignIn.getLastSignedInAccount(this); if (googleSignInAccount != null) { mDriveClient = Drive.getDriveClient(getApplicationContext(), googleSignInAccount); mDriveResourceClient = Drive.getDriveResourceClient(getApplicationContext(), googleSignInAccount); } else Toast.makeText(this, "Login again and retry", Toast.LENGTH_SHORT).show(); createContentsTask = mDriveResourceClient.createContents(); findViewById(R.id.uploadVideo).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { createFile(); } }); } private void createFile() { // [START create_file] final Task<DriveFolder> rootFolderTask = mDriveResourceClient.getRootFolder(); final Task<DriveContents> createContentsTask = mDriveResourceClient.createContents(); Tasks.whenAll(rootFolderTask, createContentsTask) .continueWithTask(new Continuation<Void, Task<DriveFile>>() { @Override public Task<DriveFile> then(@NonNull Task<Void> task) throws Exception { DriveFolder parent = rootFolderTask.getResult(); DriveContents contents = createContentsTask.getResult(); File file = new File(uri); ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buf = new byte[1024]; FileInputStream fis = new FileInputStream(file); for (int readNum; (readNum = fis.read(buf)) != -1;) { baos.write(buf, 0, readNum); } OutputStream outputStream = contents.getOutputStream(); outputStream.write(baos.toByteArray()); MetadataChangeSet changeSet = new MetadataChangeSet.Builder() .setTitle("MyVideo.mp4") // Provide you video name here .setMimeType("video/mp4") // Provide you video type here .build(); return mDriveResourceClient.createFile(parent, changeSet, contents); } }) .addOnSuccessListener(this, new OnSuccessListener<DriveFile>() { @Override public void onSuccess(DriveFile driveFile) { Toast.makeText(Upload.this, "Upload Started", Toast.LENGTH_SHORT).show(); finish(); } }) .addOnFailureListener(this, new OnFailureListener() { @Override public void onFailure(@NonNull Exception e) { Log.e(TAG, "Unable to create file", e); finish(); } }); // [END create_file] }
