Store the sqlite Database into google drive
I have tried many example and did not find any good solution.
I want to store the data of my app to store in sqlite database then sync it with the google drive account of the user who installed the app.
There is also a button which will show the data from google drive and user can edit and update the data so the updated data is then store in the google drive. I'm new in Android development please help me.
I also have applied the following example but did not succeed. https://github.com/seanpjanson/GDAADemo Create / Edit / Retrieve DB file with GDAA (Google Drive Api for Android) Unpredictable result of DriveId.getResourceId() in Google Drive Android API https://github.com/googledrive/android-quickstart
Thanks
Answer
first create a db backup in SD-card using below line
Driver_utils.create_backup(SettingActivity.this);
**add below dependencies in build.gradle **
compile 'com.google.code.gson:gson:2.2.+' compile 'com.google.android.gms:play-services-drive:10.0.1'`
in_drive.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (Utils.isInternetWorking()) {
File directorys = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Databackup");
if (directorys.exists()) {
String json = preferences_driverId.getString("drive_id", "");
DriveId driveId = gson.fromJson(json, DriveId.class);
//Update file already stored in Drive
Driver_utils.trash(driveId, google_api_client);
// Create the Drive API instance
Driver_utils.creatBackupDrive(SettingActivity.this, google_api_client);
dialog.dismiss();
Toast.makeText(getApplicationContext(), R.string.backupss, Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), R.string.inportfirest, Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(getApplicationContext(), R.string.nointe, Toast.LENGTH_LONG).show();
}
}
});
**And for Restore use this **
restore_from_drive.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// Launch user interface and allow user to select file
IntentSender intentSender = Drive.DriveApi
.newOpenFileActivityBuilder()
.setMimeType(new String[]{"application/zip"})
.build(google_api_client);
try {
startIntentSenderForResult(
intentSender, REQ_CODE_OPEN, null, 0, 0, 0);
} catch (IntentSender.SendIntentException e) {
Log.w(TAG, e.getMessage());
}
dialog.dismiss();
}
});
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == DIALOG_ERROR_CODE) {
mResolvingError = false;
if (resultCode == RESULT_OK) { // Error was resolved, now connect to the client if not done so.
if (!google_api_client.isConnecting() && !google_api_client.isConnected()) {
google_api_client.connect();
}
}
}
if (requestCode == REQ_CODE_OPEN && resultCode == RESULT_OK) {
DriveId mSelectedFileDriveId = data.getParcelableExtra(
OpenFileActivityBuilder.EXTRA_RESPONSE_DRIVE_ID);
Log.e("DriveID ---", mSelectedFileDriveId + "");
Gson gson = new Gson();
String json = gson.toJson(mSelectedFileDriveId); // myObject - instance of MyObject
editor_drive = preferences_driverId.edit();
editor_drive.putString("drive_id", json).commit();
Log.e(TAG, "driveId this 1-- " + mSelectedFileDriveId);
if (Utils.isInternetWorking()) {
//restore Drive file to SDCArd
Driver_utils.restoreDriveBackup(SettingActivity.this, google_api_client, GOOGLE_DRIVE_FILE_NAME, preferences_driverId, mfile);
Driver_utils.restore(SettingActivity.this);
} else {
Toast.makeText(getApplicationContext(), R.string.nointernets, Toast.LENGTH_LONG).show();
}
}
}

file.mkdirs();
} else {
file.getParentFile().mkdirs();
InputStream in = zfile.getInputStream(entry);
copy(in, file);
in.close();
}
}
} catch (Exception e) {
e.printStackTrace();
return false;
} finally {
try {
if (br != null) br.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
return true;

zout.putNextEntry(new ZipEntry(name));
} else {
zout.putNextEntry(new ZipEntry(name));
copy(kid, zout);
zout.closeEntry();
}
}
}
res.close();
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
