Was searching for the answer but couldent find one thats help me.
Im using volley - json request im getting error: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY
This is my Code:
public static JsonTask<GameStatusResponse> PostLiveGames(final Context ctx, ArrayList<GameStatus> liveGames)
{
ArrayList<Integer> gamesIds = new ArrayList<Integer>();
for (GameStatus gameStatus : liveGames)
{
gamesIds.add(gameStatus.ID);
}
JsonObject bodObj = new JsonObject();
bodObj.addProperty("AcceptNotification", true);
bodObj.addProperty("AppVersion", WZApp.getAppVersion(mContext));
String ids = "";
for (int i = 0; i < gamesIds.size(); i++)
{
ids = ids + "," + gamesIds.get(i);
}
ids = ids.substring(1, ids.length());
bodObj.addProperty("games", "[" + ids + "]");
System.out.println("live games object: " + bodObj.toString());
JsonTask<GameStatusResponse> task = new JsonTask<GameStatusResponse>(getURL(APIMethods.GetLiveGames.url),
GameStatusResponse.class, new JsonResponseCallback<GameStatusResponse>()
{
#Override

&& response.response.GameStatusGames.size() > 0)
System.out.println("check " + response.response.GameStatusGames.get(0).GameStatusType);
}
#Override
public void onErrorReceived(Exception error)
{
System.out.println("we got error in live games: " + error.getMessage());
}
});
task.addCustomDeserializer(betStatusTypeDeserializer, DataEnums.BetStatusType.class)

Your output seems odd. Is JSON result being coined by yourself?
Both response and Odd fields seem to start with ( ) instead of [ ] which denotes an array. On top of that, this do not even seems valid JSON at all.
In JSON one doesn't use =, but : and fields are separated by ; instead of ,. For example:
{
meta : {
message : OK,
"operation_message" : "<null>",
operationstatus : 0,
status : 200,
},
response : [{
GameResult : 3,
GameStatusType : 3,
ID : 106448,
Odds : [{
OddID : 84001,
Outcomes : [{
ID : 4,
Name : 1
}, {
ID : 5,
Name : X
}, {
ID : 6,
Name : 2
}],
Result : "<null>",
TypeID : 10,
TypeName : ThreeWay,
Value : "<null>"
}],
"T1_Result" : 0,
"T2_Result" : 0,
TotalBets : 76,
WinnerID : "<null>",
isEnded : 0
}, {

}
The line 329 is this
string level = infoAchie[1];
The problem is coming from the last comma you are adding in the string you are adding to your PlayerPrefs in this part:
if (!PlayerPrefs.HasKey(Achievement_data_key))
{
string achi = "";
for (int i = 1; i <= 22; i++)
{
achi += i + "-1-0-0,";
}
//Debug.Log("Create new achievement " + achi);
PlayerPrefs.SetString(Achievement_data_key, achi);
}
This code generates this string:
1-1-0-0,2-1-0-0,3-1-0-0,4-1-0-0,5-1-0-0,6-1-0-0,7-1-0-0,8-1-0-0,9-1-0-0,10-1-0-0,11-1-0-0,12-1-0-0,13-1-0-0,14-1-0-0,15-1-0-0,16-1-0-0,17-1-0-0,18-1-0-0,19-1-0-0,20-1-0-0,21-1-0-0,22-1-0-0,
Keep in memory that last comma at the end of the string.
You are later doing a split on the ',' character, and iterating over them.
string[] achie = achievement.Split(',');
for (int i = 0; i< dataAchievementCache.Length; i++)
{
//Debug.Log(achie[i]);
string[] infoAchie = achie[i].Split('-');
string group = infoAchie[0];
string level = infoAchie[1];
...
}
The problem is that by doing so, your achie string array contains an empty last element. So when you are later splitting on the "-" character, your infoAchie string array only contains one element: the empty string. The first line:
string group = infoAchie[0];
Still works, but is filled with the empty string. Then:
string level = infoAchie[1];
Can't work, as you are indeed out of the bounds of the infoAchie array.
The solution would be to add the comma to your string only if it is not the last element.
Also, I strongly advise you to use a StringBuilder over a simple string for optimization purposes. Your code could then look like, for instance:
if (!PlayerPrefs.HasKey(Achievement_data_key))
{
StringBuilder achi = new StringBuilder();
for (int i = 1; i <= 22; i++)
{
achi.Append(i).Append("-1-0-0");
if(i != 22)
achi.Append(",");
}
//Debug.Log("Create new achievement " + achi);
PlayerPrefs.SetString(Achievement_data_key, achi.ToString());
}
Which generates this string:
1-1-0-0,2-1-0-0,3-1-0-0,4-1-0-0,5-1-0-0,6-1-0-0,7-1-0-0,8-1-0-0,9-1-0-0,10-1-0-0,11-1-0-0,12-1-0-0,13-1-0-0,14-1-0-0,15-1-0-0,16-1-0-0,17-1-0-0,18-1-0-0,19-1-0-0,20-1-0-0,21-1-0-0,22-1-0-0
I'd like to use ExoPlayer2 with playlists having possibility to dinamically change the tracks (add or remove them from playlist) and change the loop settings.
Since ConcatenatingMediaSource has static arrays (and not lists), I'm implementing a DynamicMediaSource, like Concatenating one but with lists instead of arrays and one mode method addSource to add one more media source to the list.
public void addSource(MediaSource mediaSource) {
this.mediaSources.add(mediaSource);
duplicateFlags = buildDuplicateFlags(this.mediaSources);
if(!mediaSources.isEmpty())
prepareSource(mediaSources.size() -1);
else
prepareSource(0);
}
When I invoke addSource
MediaSource ms = buildMediaSource(mynewuri, null);
mediaSource.addSource(ms);
the track is added to the arrays but it seems something is missing because I always obtain ArrayOutOfBoundsException in createPeriod method.
In createPeriod the method
mediaSources.get(sourceIndex)...
is trying to access the index = mediaSources.size().
Can you help me?
I eventually managed it.
It was my fault during the conversion from arrays to lists.
I had to use SparseArrays for timelines and manifests and everything began to work.
In the DynamicMediaSource simply set the following types:
private final List<MediaSource> mediaSources;
private final SparseArray<Timeline> timelines;
private final SparseArray<Object> manifests;
private final Map<MediaPeriod, Integer> sourceIndexByMediaPeriod;
private SparseArray<Boolean> duplicateFlags;
you have to use sparse arrays to set the proper values into the timelines and manifests in the method
private void handleSourceInfoRefreshed(int sourceFirstIndex, Timeline sourceTimeline,
Object sourceManifest) {
// Set the timeline and manifest.
timelines.put(sourceFirstIndex, sourceTimeline);
manifests.put(sourceFirstIndex, sourceManifest);
// Also set the timeline and manifest for any duplicate entries of the same source.
for (int i = sourceFirstIndex + 1; i < mediaSources.size(); i++) {
if (mediaSources.get(i).equals(mediaSources.get(sourceFirstIndex))) {
timelines.put(i, sourceTimeline);
manifests.put(i, sourceManifest);
}
}
for(int i= 0; i<mediaSources.size(); i++){
if(timelines.get(i) == null){
// Don't invoke the listener until all sources have timelines.
return;
}
}

I can't see the error, I'm having this problem for a long time already... My parcelable class crashes if it is recreated, but I can't find the problem...
I checked the order of writing/reading data.
I checked the functions I use (direct reading/writing vs my custum null save functions)
I marked the line in the first code block that created following exception: java.lang.ArrayIndexOutOfBoundsException: length=5; index=5

you loop from 0 to 4, but source.readInt() was already called once, so you called it 5 times in total.
ContactType contains 5 values, from index 0 to index 4. You are trying to access the index 5, which does not exist.
mMatchesDataLoaded.add(ContactType.values()[source.readInt()]);
source.readInt() gives you a 5, try to figure out, with debug, why does it contain this value.
My guess is that writeToParcel writes this 5, try to inspect mMatchesDataLoaded which maybe contains some additional unwanted data.
i'm using feed.jar of libs-for-android, and i need to parse json data.
