++++Object+o+=+this.opt(index);
++++this.myArrayList.removeElementAt(index);

i guess you are using Me version, i suggest to add this block of function manually, in your code (JSONArray.java) :

<pre><code>public Object remove(int index) {
 Object o = this.opt(index);
 this.myArrayList.removeElementAt(index);
 return o;
}
</code></pre>

In java version they use ArrayList, in ME Version they use Vector.

You can use reflection 

A Chinese website provides a relevant solution: <a href="http://blog.csdn.net/peihang1354092549/article/details/41957369" rel="nofollow">http://blog.csdn.net/peihang1354092549/article/details/41957369</a> 
If you don't understand Chinese, please try to read it with the translation software. 

He provides this code for the old version: 

<pre><code>public void JSONArray_remove(int index, JSONArray JSONArrayObject) throws Exception{
 if(index &lt; 0)
 return;
 Field valuesField=JSONArray.class.getDeclaredField("values");
 valuesField.setAccessible(true);
 List&lt;Object&gt; values=(List&lt;Object&gt;)valuesField.get(JSONArrayObject);
 if(index &gt;= values.size())
 return;
 values.remove(index);

In my case I wanted to remove jsonobject with status as non zero value, so what I did is made a function "removeJsonObject" which takes old json and gives required json and called that function inside the constuctor.

<pre><code>public CommonAdapter(Context context, JSONObject json, String type) {
 this.context=context;
 this.json= removeJsonObject(json);
 this.type=type;
 Log.d("CA:", "type:"+type);

 }

public JSONObject removeJsonObject(JSONObject jo){
 JSONArray ja= null;
 JSONArray jsonArray= new JSONArray();
 JSONObject jsonObject1=new JSONObject();

 try {
 ja = jo.getJSONArray("data");

 } catch (JSONException e) {
 e.printStackTrace();
 }
 for(int i=0; i&lt;ja.length(); i++){
 try {

 if(Integer.parseInt(ja.getJSONObject(i).getString("status"))==0)
 {
 jsonArray.put(ja.getJSONObject(i));
 Log.d("jsonarray:", jsonArray.toString());
 }


 } catch (JSONException e) {
 e.printStackTrace();
 }
 }
 try {
 jsonObject1.put("data",jsonArray);
 Log.d("jsonobject1:", jsonObject1.toString());

 return jsonObject1;
 } catch (JSONException e) {
 e.printStackTrace();
 }
 return json;
 }

I am building one app in which I request a PHP file from server. This PHP file returns a JSONArray having JSONObjects as its elements e.g., 

<pre><code>[ 
 {
 "uniqid":"h5Wtd", 
 "name":"Test_1", 
 "address":"tst", 
 "email":"ru_tst@tst.cc", 
 "mobile":"12345",
 "city":"ind"
 },
 {...},
 {...},
 ...
]
</code></pre>

my code:

<pre><code>/* jArrayFavFans is the JSONArray i build from string i get from response.
 its giving me correct JSONArray */
JSONArray jArrayFavFans=new JSONArray(serverRespons);
for (int j = 0; j &lt; jArrayFavFans.length(); j++) {
 try {
 if (jArrayFavFans.getJSONObject(j).getString("uniqid").equals(id_fav_remov)) {
 //jArrayFavFans.getJSONObject(j).remove(j); //$ I try this to remove element at the current index... But remove doesn't work here ???? $
 //int index=jArrayFavFans.getInt(j);
 Toast.makeText(getParent(), "Object to remove...!" + id_fav_remov, Toast.LENGTH_SHORT).show();
 }
 } catch (JSONException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }
}
</code></pre>
