问题
I used Android Drive Api to upload my files on Drive.I created a folder("NewFolder") on Google Drive root and created a inner folder("InnerFolder") inside my "NewFolder" from android app using following code.Then I write my files on this "InnerFolder" from my android app.
My app create the "InnerFolder" on first time installation on my device only.Then uninstall and reinstall App will not created folder again(Stored created folder Drive Id(like DriveId:yrjundeen12cnfe) in local file).
My Code works fine on first time Installation.But If I uninstall and reinstall app many times and I try to upload on Google Drive,I got error as "Invalid parent folder" on callback method of createFile.
First Time Folder Creation code:
private void createGalleryFolder() {
DriveFolder folder = Drive.DriveApi.getRootFolder(googleApiClient);
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setTitle(AppConstants.DEFAULT_GALLERY_NAME).build();
folder.createFolder(googleApiClient, changeSet).setResultCallback(
createRootFolderCallback);
}
final ResultCallback<DriveFolderResult> createRootFolderCallback = new ResultCallback<DriveFolderResult>() {
@Override
public void onResult(DriveFolderResult result) {
if (!result.getStatus().isSuccess()) {
showError();
return;
}
// Root folder created Successfully
DriveId mFolderDriveId = result.getDriveFolder().getDriveId();
AppUtilities.saveOnLocalFile(mFolderDriveId, AppConstants.ROOT_FOLDER_ID_FILE);
if (!deviceID.equalsIgnoreCase("")) {
DriveFolder folder = Drive.DriveApi.getFolder(googleApiClient,
result.getDriveFolder().getDriveId());
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setTitle(deviceID).build();
folder.createFolder(googleApiClient, changeSet)
.setResultCallback(createInnerFolderCallback);
} else {
showError(); }
}
};
final ResultCallback<DriveFolderResult> createInnerFolderCallback = new ResultCallback<DriveFolderResult>() {
@Override
public void onResult(DriveFolderResult result) {
if (!result.getStatus().isSuccess()) {
showError();
return;
}
// IMEI folder created successfully inside the Root folder
DriveId mFolderDriveId = result.getDriveFolder().getDriveId();
AppUtilities.saveOnLocalFile(mFolderDriveId, AppConstants.INNER_FOLDER_ID_FILE);
// Success
}
};
File Upload code:
private void saveFileToDrive(final Bitmap bitmapToSave,final File imageFile,final String imageName) {
Drive.DriveApi.newDriveContents(googleApiClient).setResultCallback(driveContentsCallback);
}
final private ResultCallback<DriveContentsResult> driveContentsCallback =
new ResultCallback<DriveContentsResult>() {
@Override
public void onResult(DriveContentsResult result) {
if(!result.getStatus().isSuccess()){
Log.i("Test1", "Failed to create new contents");
return;
}
Log.i("Test1", "New contents created");
//Write image data to OutputStream
OutputStream outputStream = result.getDriveContents().getOutputStream();
ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream();
bitmapToSave.compress(Bitmap.CompressFormat.JPEG, 100, bitmapStream);
try {
outputStream.write(bitmapStream.toByteArray());
DriveFolder folder = Drive.DriveApi.getFolder(googleApiClient, DriveId.decodeFromString(getFolderDriveID()));
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setTitle(imageName)
.setMimeType("image/jpeg")
.setStarred(false).build();
folder.createFile(googleApiClient, changeSet, result.getDriveContents()).setResultCallback(fileCallback);
} catch (IOException e) {
Log.i("Test1","Unable to write file contents");
}
}
};
final private ResultCallback<DriveFileResult> fileCallback =
new ResultCallback<DriveFileResult>() {
@Override
public void onResult(DriveFileResult result) {
if (!result.getStatus().isSuccess()) {
Log.i("Test1","Error while trying to create the file "+result.getStatus().getStatusMessage());
return;
}
Log.i("Test1","Created a file: " + result.getDriveFile().getDriveId());
result.getDriveFile().getMetadata(googleApiClient).setResultCallback(fileUploadedResultCallback);
}
};
final private ResultCallback<MetadataResult> fileUploadedResultCallback =
new ResultCallback<MetadataResult>() {
@Override
public void onResult(MetadataResult result) {
if(!result.getStatus().isSuccess()){
Log.i("Test1", "Failed to upload");
return;
}
Log.i("Test1", "File uploaded");
}
};

Do not rely on GDAA's DriveId for any caching or possibly addressing of Drive object (file/folder) beyond the app and device scope. This ID is coming from Google Play Services instance on your device (so it is not even valid on a different device using the same app - even if file/folder is still visible under the FILE scope). I vaguely remember 'losing' it even when clearing the Google Play Services (GooPS) cache or even re-installing GooPS. But this might have been fixed. My last encounter with GDAA was a few months ago.
Instead, there is a 'ResourceId', that is used in RESTFul API (known as plain 'id') - see SO 21800257. This string uniquely represents the Drive object and can be ported and used everywhere (it is even a part of HTTP address in Drive Web interface).
Unfortunately, ResourceId is not immediately available (until GDAA commits the the object) - SO 22432431
Good Luck

You can't access file and folders created in other apps (including the Drive Web and Android apps) unless the user explicitly authorizes your app to access them using the file picker.
If you created the folder using your Android app, then uninstall and reinstall your app, your app should still be able to access the folder as authorization is tied to your Developer Console application ID which doesn't change between installs.
This behavior also means the Web version of your app can access files created by the Android version.
