How To Create Multiple Files Programmatically Using Drive Api For Android?
I am able to create a single file in google drive using CreateFileActivity.java.But i want to upload two or more files to the google drive at a time.How is it possible to create mu
Solution 1:
Assuming, you have multiple files on your Android device, represented by java.io.File objects with known names (titles) and mime type(s):
java.io.File[] files = {...};
String[] names[] = {...};
String[] mimes[] = {...};
You can use this construct to create a set of files in Google drive (in the root, for example):
com.google.android.gms.common.api.GoogleApiClient mGooApiClient;
voidfoo() {
for (inti=0; i < files.length; i++) {
createFile(null, names[i], mimes[i], files[i]);
}
}
/***********************************************************************
* create file in GOODrive
* @param pFldr parent's ID, (null for root)
* @param titl file name
* @param mime file mime type
* @param file java.io.File (with content) to create
*/voidcreateFile(DriveFolder pFldr, final String titl, final String mime, final File file) {
DriveIddId=null;
if (mGooApiClient != null && mGooApiClient.isConnected() && titl != null && mime != null && file != null) try {
finalDriveFolderparent= pFldr != null ? pFldr : Drive.DriveApi.getRootFolder(mGooApiClient);
if (pFldr == null) return; //----------------->>>
Drive.DriveApi.newDriveContents(mGAC).setResultCallback(newResultCallback<DriveContentsResult>() {
@OverridepublicvoidonResult(DriveContentsResult driveContentsResult) {
DriveContentscont= driveContentsResult != null && driveContentsResult.getStatus().isSuccess() ?
driveContentsResult.getDriveContents() : null;
if (cont != null) try {
OutputStreamoos= cont.getOutputStream();
if (oos != null) try {
InputStreamis=newFileInputStream(file);
byte[] buf = newbyte[4096];
int c;
while ((c = is.read(buf, 0, buf.length)) > 0) {
oos.write(buf, 0, c);
oos.flush();
}
}
finally { oos.close();}
MetadataChangeSetmeta=newBuilder().setTitle(titl).setMimeType(mime).build();
parent.createFile(mGooApiClient, meta, cont).setResultCallback(newResultCallback<DriveFileResult>() {
@OverridepublicvoidonResult(DriveFileResult driveFileResult) {
DriveFiledFil= driveFileResult != null && driveFileResult.getStatus().isSuccess() ?
driveFileResult.getDriveFile() : null;
if (dFil != null) {
// save dFil, report success
} else {
// handle error
}
}
});
} catch (Exception e) {e.printStackTrace();}
}
});
} catch (Exception e) { e.printStackTrace(); }
}
Don't forget to save the DriveFile (or DriveId) or the created files.
Good Luck
