问题
I have spent too much time on this so I would like to ask about it. I want to create and upload google spreadsheet using android. I know that I should use Drive API to do this. I know how to create file using this API(even excel file) but when setMimeType is set to application/vnd.google-apps.spreadsheet I receive an error on the device: Error while trying to create the file.
@Override
public void onConnected(Bundle connectionHint) {
super.onConnected(connectionHint);
// create new contents resource
Drive.DriveApi.newDriveContents(getGoogleApiClient())
.setResultCallback(driveContentsCallback);
}
final private ResultCallback<DriveContentsResult> driveContentsCallback = new
ResultCallback<DriveContentsResult>() {
@Override
public void onResult(DriveContentsResult result) {
if (!result.getStatus().isSuccess()) {
showMessage("Error while trying to create new file contents");
return;
}
final DriveContents driveContents = result.getDriveContents();
// Perform I/O off the UI thread.
new Thread() {
@Override
public void run() {
// write content to DriveContents
OutputStream outputStream = driveContents.getOutputStream();
Writer writer = new OutputStreamWriter(outputStream);
try {
writer.write("Hello World!");
writer.write("Hello World!");
writer.close();
} catch (IOException e) {
Log.e(TAG, e.getMessage());
}
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setTitle("Orders")
.setMimeType("application/vnd.google-apps.spreadsheet")
.setStarred(true).build();
// create a file on root folder
Drive.DriveApi.getRootFolder(getGoogleApiClient())
.createFile(getGoogleApiClient(), changeSet, driveContents)
.setResultCallback(fileCallback);
}
}.start();
}
};
final private ResultCallback<DriveFileResult> fileCallback = new
ResultCallback<DriveFileResult>() {
@Override
public void onResult(DriveFileResult result) {
if (!result.getStatus().isSuccess()) {
showMessage("Error while trying to create the file");
return;
}
showMessage("Created a file with content: " + result.getDriveFile().getDriveId());
storeId(result.getDriveFile().getDriveId());
kill_activity();
}
};v

The GDAA does not currently support creation Google Docs files. You will have to use the Google Drive REST API in your Android application to do this.

@user3212019, You can upload a excel spread sheet in google drive from your android app, just follow as below.
I think you aware of Quick Start on Google Android site.
Now create a excel sheet by using jxl jar library
Now follow the Start Integrating Google Sign-In and Integrate Google SignIn with Drive scope (Drive.SCOPE_FILE) in your app.
Now final and last copy paste below activity code in your activity and then give a excel sheet path in saveFileToDrive(file_path) method.
public class UploadFileInGoogleDriveActivity extends Activity {
private static final String TAG = "tejadroid-quickstart";
private static final int REQUEST_CODE_SIGN_IN = 0;
private GoogleSignInClient mGoogleSignInClient;
private DriveClient mDriveClient;
private DriveResourceClient mDriveResourceClient;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
signIn();
}
/**
* Start sign in activity.
*/
private void signIn() {
Log.i(TAG, "Start sign in");
mGoogleSignInClient = buildGoogleSignInClient();
startActivityForResult(mGoogleSignInClient.getSignInIntent(), REQUEST_CODE_SIGN_IN);
}
/**
* Build a Google SignIn client.
*/
private GoogleSignInClient buildGoogleSignInClient() {
GoogleSignInOptions signInOptions =
new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestScopes(Drive.SCOPE_FILE)
.build();
return GoogleSignIn.getClient(this, signInOptions);
}
@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQUEST_CODE_SIGN_IN:
Log.i(TAG, "Sign in request code");
// Called after user is signed in.
if (resultCode == RESULT_OK) {
Log.i(TAG, "Signed in successfully.");
// Use the last signed in account here since it already have a Drive scope.
mDriveClient = Drive.getDriveClient(this, GoogleSignIn.getLastSignedInAccount(this));
// Build a drive resource client.
mDriveResourceClient =
Drive.getDriveResourceClient(this, GoogleSignIn.getLastSignedInAccount(this));
// Excel Sheet path from SD card
final String filePath = "/storage/emulated/0/Expense Manager/ExpenseReport/ExpenseDiary.xls";
saveFileToDrive(filePath);
}
break;
}
}
/**
* Create a new file and save it to Drive.
*/
private void saveFileToDrive(final String filePath) {
// Start by creating a new contents, and setting a callback.
Log.i(TAG, "Creating new contents.");
mDriveResourceClient
.createContents()
.continueWithTask(
new Continuation<DriveContents, Task<Void>>() {
@Override
public Task<Void> then(@NonNull Task<DriveContents> task) throws Exception {
return createFileIntentSender(task.getResult(), new File(filePath));
}
})
.addOnFailureListener(
new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.w(TAG, "Failed to create new contents.", e);
}
});
}
/**
* Creates an {@link IntentSender} to start a dialog activity with configured {@link
* CreateFileActivityOptions} for user to create a new photo in Drive.
*/
private Task<Void> createFileIntentSender(DriveContents driveContents, File file) throws Exception {
Log.i(TAG, "New contents created.");
OutputStream outputStream = driveContents.getOutputStream();
InputStream in = new FileInputStream(file);
try {
try {
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
outputStream.write(buf, 0, len);
}
} finally {
outputStream.close();
}
} finally {
in.close();
}
// Create the initial metadata - MIME type and title.
// Note that the user will be able to change the title later.
MetadataChangeSet metadataChangeSet =
new MetadataChangeSet.Builder()
.setMimeType("application/vnd.ms-excel")
.setTitle("ExcelSheet.xls")
.build();
// Set up options to configure and display the create file activity.
CreateFileActivityOptions createFileActivityOptions =
new CreateFileActivityOptions.Builder()
.setInitialMetadata(metadataChangeSet)
.setInitialDriveContents(driveContents)
.build();
return mDriveClient
.newCreateFileActivityIntentSender(createFileActivityOptions)
.continueWith(
new Continuation<IntentSender, Void>() {
@Override
public Void then(@NonNull Task<IntentSender> task) throws Exception {
startIntentSenderForResult(task.getResult(), REQUEST_CODE_CREATOR, null, 0, 0, 0);
return null;
}
});
}
}
Just debug app and look in to Google Drive there your file exist in root folder of drive.
