Can't get media metadata compat string

I'm creating a kotlin app. I have an issue with mediaMetadataCompat. Maybe I have to put data to extras? I put data like this
audios = allAudios!!.map { audio ->
MediaMetadataCompat.Builder()
.putString(METADATA_KEY_WRITER, audio.writer._id)
.putString(METADATA_KEY_ARTIST, audio.writer.name)
.putString(METADATA_KEY_DISPLAY_SUBTITLE, audio.writer.name)
.putString(METADATA_KEY_MEDIA_ID, audio._id)
.putString(METADATA_KEY_TITLE, audio.title)
.putString(METADATA_KEY_DISPLAY_TITLE, audio.title)
.putString(METADATA_KEY_DISPLAY_ICON_URI, audio.writer.image)
.putString(METADATA_KEY_DATE, audio.createdAt)
.putString(METADATA_KEY_MEDIA_URI, audio.filePath)
.putString(METADATA_KEY_DISPLAY_DESCRIPTION, audio.description)
.build()
}
Get it like this
fun MediaMetadataCompat.toAudio(): Audio? {
return let {
Audio(
_id = it.description.mediaId ?: "",
title = it.description.title.toString(),
filePath = it.description.mediaUri.toString(),
description = it.description.description.toString(),
writer = User(
_id = it.description.extras?.getString("writerId").toString(),
name = it.description.subtitle.toString(),
image = it.description.iconUri.toString()
),
tags = listOf("Shit"),
listened = 1,
language = "en",
isForKids = false,
duration = 70,
createdAt = "2020:01:01"
)
}
}
It only gives my title, icon_uri, media_uri and media_id

Sharing a small part of my code:
Below is building object of MediaMetaDataCompat. I am adding couple of data there and have used in different parts of app.
var media = MediaMetadataCompat.Builder()
.putString(MediaMetadataCompat.METADATA_KEY_MEDIA_ID, data.id.toString())
.putString(MediaMetadataCompat.METADATA_KEY_ARTIST, data.artist_name)
.putString(MediaMetadataCompat.METADATA_KEY_TITLE, data.title)
.putString(MediaMetadataCompat.METADATA_KEY_MEDIA_URI, data.audio_path)
.putString(MediaMetadataCompat.METADATA_KEY_DATE, data.track_year)
.putString(MediaMetadataCompat.METADATA_KEY_DISPLAY_ICON_URI, data.image_path)
.putLong(MediaMetadataCompat.METADATA_KEY_DURATION, data.duration.toLong())
.build()
mediaItem is object of MediaMetadataCompat and that is how I am getting values of the fields which was added to object.
mediaItem is object of MediaMetadataCompat
var artist = mediaItem.bundle.getString(MediaMetadataCompat.METADATA_KEY_ARTIST)!!
var title = mediaItem.bundle.getString(MediaMetadataCompat.METADATA_KEY_TITLE)!!
var duration = mediaItem.bundle.getLong(MediaMetadataCompat.METADATA_KEY_DURATION)!!
var icon = mediaItem.bundle.getString(MediaMetadataCompat.METADATA_KEY_DISPLAY_ICON_URI)!!

Get JSON tag with random name

I have this JSON:
{
"-1":{
"name":"Ad hoc",
"modifiedBy":"",
}
},
"9":{
"name":"my name",
"modifiedBy":"me",
}
}
}
The tags "-1" and "9" are IDs that I don't know.
I need get the tag "9" using the "name" "my name" with a JSON path.
How can I do that? I use Java.

I'm assuming the JSON in your question is in Java's JSONObject form. Let's call this object myjson. Let's also say you are trying to get the ID of the sub-object that has an internal "name" value of "Ad hoc":
String nameKey = "Ad hoc";
String theID = "";
Set keys = myjson.keySet();
Iterator iter = keys.iterator();
while(iter.hasNext()) {
String key = (String)iter.next();
String name = (String)jsonObject.getJSONObject(key).get("name");
if (name.equals(nameKey)) {
theID = key;
}
}
The variable theID should now contain the ID you want. If no match is found, theID will be an empty string.

Convert JSON response to Array format in Android

I am getting response from server in JSONArray format. I am not able to retrieve the contents of array also my JSONArray has no Square brackets.
I am passing the response in php as json_encode($array) in server side
response {
community = “worker”
communitystr = "<null>";
workspace = abs;
email = "<null>";
admin = false;
persona = "<null>";
userinfo = {
info = {
contact1 = {
firstname = “jon”;
lastname = “Doe”
phone = “9885678905”;
objectname = contact;
id = 9;
};
event1 = {
eventname = “party”;
description = "";
order = 6;
id = 4;
objectname = events;
};
files = {
filename = “sample”;
description = "";
order = 11;
id = 11;
objectname = files;
};
};
};
};
I checked many links and all have used JSONObject(). But same is not working for me.
How do I get each values in this JSON Response ?

You have to use
: instead of =
, instead of ;
...
Watch out following format:
{
"Herausgeber": "Xema",
"Nummer": "1234-5678-9012-3456",
"Deckung": 2e+6,
"Waehrung": "EURO",
"Inhaber":
{
"Name": "Mustermann",
"Vorname": "Max",
"maennlich": true,
"Hobbys": [ "Reiten", "Golfen", "Lesen" ],
"Alter": 42,
"Kinder": [],
"Partner": null
}
}
Your code seems like to be more JavaScript-Object like :-)

Your response is not valid JSON object.
You can validate the JSON via some online tool, like http://jsonlint.com/
Full specification can be found in RFC 7159 https://www.rfc-editor.org/rfc/rfc7159.
Basically you should look how to encode the values into JSON format in correct way. For that you can refer to PHP Array to JSON Array using json_encode();

How to get and set a value for a key in JSON file?

I am working with Java and Samba and Currently I have a file called file.plist that contains a json text that use (), = and ; like this:
{
"sites" = (
{
"sitename" = "default";
"blackList" = (
{
"NAME" = "SQL";
},
{
"NAME" = "CMD";
}
);
}
)
}
From Java I want to read the value of the key "blackList" and also I need to set a new value for that key in the same format, but this JSON is distinct because uses () = ; instead of [] : ,
Exists any way or library to work with this JSON format?
I clarify that the File format is not .json, is .plist

CloudSearch deleteByQuery

The official Solr Java API has a deleteByQuery operation where we can delete documents that satisfy a query. The AWS CloudSearch SDK doesn't seem to have matching functionality. Am I just not seeing the deleteByQuery equivalent, or is this something we'll need to roll our own?
Something like this:
SearchRequest searchRequest = new SearchRequest();
searchRequest.setQuery(queryString);
searchRequest.setReturn("id,version");
SearchResult searchResult = awsCloudSearch.search(searchRequest);
JSONArray docs = new JSONArray();
for (Hit hit : searchResult.getHits().getHit()) {
JSONObject doc = new JSONObject();
doc.put("id", hit.getId());
// is version necessary?
doc.put("version", hit.getFields().get("version").get(0));
doc.put("type", "delete");
docs.put(doc);
}
UploadDocumentsRequest uploadDocumentsRequest = new UploadDocumentsRequest();
StringInputStream documents = new StringInputStream(docs.toString());
uploadDocumentsRequest.setDocuments(documents);
UploadDocumentsResult uploadResult = awsCloudSearch.uploadDocuments(uploadDocumentsRequest);
Is this reasonable? Is there an easier way?

You're correct that CloudSearch doesn't have an equivalent to deleteByQuery. Your approach looks like the next best thing.
And no, version is not necessary -- it was removed with the CloudSearch 01-01-2013 API (aka v2).

CloudSearch doesn't provide delete as query, it supports delete in a slightly different way i.e. build json object having only document id (to be deleted) and operation should be specified as delete. These json objects can be batched together but batch size has to be less than 5 MB.
Following class supports this functionality, you just pass its delete method the array of ids to be deleted:
class AWS_CS
{
protected $client;
function connect($domain)
{
try{
$csClient = CloudSearchClient::factory(array(
'key' => 'YOUR_KEY',
'secret' => 'YOUR_SECRET',
'region' => 'us-east-1'
));
$this->client = $csClient->getDomainClient(
$domain,
array(
'credentials' => $csClient->getCredentials(),
'scheme' => 'HTTPS'
)
);
}
catch(Exception $ex){
echo "Exception: ";
echo $ex->getMessage();
}
//$this->client->addSubscriber(LogPlugin::getDebugPlugin());
}
function search($queryStr, $domain){
$this->connect($domain);
$result = $this->client->search(array(
'query' => $queryStr,
'queryParser' => 'lucene',
'size' => 100,
'return' => '_score,_all_fields'
))->toArray();
return json_encode($result['hits']);
//$hitCount = $result->getPath('hits/found');
//echo "Number of Hits: {$hitCount}\n";
}
function deleteDocs($idArray, $operation = 'delete'){
$batch = array();
foreach($idArray as $id){
//dumpArray($song);
$batch[] = array(
'type' => $operation,
'id' => $id);
}
$batch = array_filter($batch);
$jsonObj = json_encode($batch, JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP);
print_r($this->client->uploadDocuments(array(
'documents' => $jsonObj,
'contentType' =>'application/json'
)));
return $result['status'] == 'success' ? mb_strlen($jsonObj) : 0;
}
}
