I made general Class called BaseActivity.java and in that I define volley function. Also I extends BaseActivity class to each activity and use method to call web api.
Code is given bellow.
public void callVolley(final Context cContext, String mMethodType, final String mMethodname, String URL,
final HashMap<String, String> mMap, int initialTimeoutMs, boolean shouldCache, int maxNumRetries,
Boolean isProgressDailogEnable, Boolean isCancelable, final Activity aActivity) {
// TODO Auto-generated method stub
mMap.put("deviceType", "1");
SharedPreferences setting = getSharedPreferences(Constant.PREFRENCE_NAME, MODE_PRIVATE);
mMap.put("loginUserId", setting.getString("userId", "") + "");
mMap.put("deviceToken", "" + setting.getString("deviceToken", ""));
mMap.put("deviceId", setting.getString("deviceId", "") + "");
if (Constant.d) Log.i(mMethodname + "==>", mMap.toString() + "");
if (!isOnline(cContext)) {
showErrorDailog(aActivity, Constant.PleaseCheckInternetConnection, R.drawable.icon);
} else {
StringRequest jsObjRequest;
int reqType = 0;
String RequestURL = URL.trim();
queue = Volley.newRequestQueue(cContext);
if (isProgressDailogEnable) {
customLoaderDialog = new CustomLoaderDialog(cContext);
customLoaderDialog.show(isCancelable);
customLoaderDialog.dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
// finish();
}
});
}
if (mMethodType.trim().equalsIgnoreCase("GET"))
reqType = com.android.volley.Request.Method.GET;
else if (mMethodType.trim().equalsIgnoreCase("POST"))
reqType = com.android.volley.Request.Method.POST;
if (RequestURL.equals(""))
RequestURL = Constant.WEBSERVICE_URL;
else
RequestURL = URL;
if (Constant.d) Log.d("reqType", reqType + "");
jsObjRequest = new StringRequest(reqType, RequestURL, new com.android.volley.Response.Listener<String>() {
@Override
public void onResponse(String response) {
if (Constant.d) Log.d("response==>" + mMethodname, "" + response);
if (customLoaderDialog != null) {
try {
customLoaderDialog.hide();
} catch (Exception e) {
e.printStackTrace();
}
}
if (response == null || response.length() == 0) {
IVolleyRespose iVolleyRespose = (IVolleyRespose) aActivity;
iVolleyRespose.onVolleyResponse(RESPONSE_ERROR, response, mMethodname);
} else {
JSONObject json_str;
try {
json_str = new JSONObject(response);
int status = json_str.getInt("status");
if (status == 101) {
AlertDialog alertDialog = new AlertDialog.Builder(aActivity).create();
alertDialog.setTitle(Constant.Alert_Name);
alertDialog.setMessage(json_str.getString("message") + "");
alertDialog.setCancelable(false);
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
SharedPreferences setting = getSharedPreferences(Constant.PREFRENCE_NAME, MODE_PRIVATE);
setting.edit().clear().commit();
ExitActivity.exitApplication(aActivity);
finish();
System.exit(0);
}
});
alertDialog.show();
} else {
IVolleyRespose iVolleyRespose = (IVolleyRespose) aActivity;
iVolleyRespose.onVolleyResponse(RESPONSE_OK, response, mMethodname);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}, new com.android.volley.Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError arg0) {
// TODO Auto-generated method stub
IVolleyRespose iVolleyError = (IVolleyRespose) aActivity;
iVolleyError.onVolleyError(RESPONSE_ERROR, "Error", mMethodname);
if (customLoaderDialog != null) {
customLoaderDialog.hide();
}
}
}) {
@Override
protected Map<String, String> getParams() {
String strRequest = "";
try {
strRequest = getWebservicejsObjRequestforvolley(mMethodname, mMap);
if (Constant.d) Log.d("Request==>", strRequest + "");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Map<String, String> params = new HashMap<>();
params.put("json", strRequest);
return params;
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
};
//if(Constant.d) Log.d("Request==>", jsObjRequest+"");
jsObjRequest.setTag(mMethodname);
jsObjRequest.setShouldCache(shouldCache);
jsObjRequest.setRetryPolicy(new DefaultRetryPolicy(initialTimeoutMs, maxNumRetries, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
queue.add(jsObjRequest);
}
}
Above is the code which I used and it gives some time OutOfMemoryError exceptoin

Issue is I cannot found why this error occur Randomly when I use application for 5 to 10 min. If any one face this type of error then solution is appreciated.
