我正在创建一个执行OTP验证方法的应用程序。 我按照此链接http://www.androidhive.info/2015/08/android-adding-sms-verification-like-whatsapp-part-2/
中的说明实现了代码但是当我点击app app中的NEXT按钮时强行关闭
我得到错误的函数是：
private void requestForSMS(final String name, final String email, final String mobile) {
StringRequest strReq = new StringRequest(Request.Method.POST,
Config.URL_REQUEST_SMS, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.d(TAG, response.toString());
try {
JSONObject responseObj = new JSONObject(response);
// Parsing json object response
// response will be a json object
boolean error = responseObj.getBoolean("error");
String message = responseObj.getString("message");
// checking for error, if not error SMS is initiated
// device should receive it shortly
if (!error) {
// boolean flag saying device is waiting for sms
pref.setIsWaitingForSms(true);
// moving the screen to next pager item i.e otp screen
viewPager.setCurrentItem(1);
txtEditMobile.setText(pref.getMobileNumber());
layoutEditMobile.setVisibility(View.VISIBLE);
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(),
"Error: " + message,
Toast.LENGTH_LONG).show();
}
// hiding the progress bar
progressBar.setVisibility(View.GONE);
} catch (JSONException e) {
//Toast.makeText(getApplicationContext(),"Error: " + e.getMessage(),Toast.LENGTH_LONG).show();
progressBar.setVisibility(View.GONE);
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
//Log.e(TAG, "Error: " + error.getMessage());
//Toast.makeText(getApplicationContext(),error.getMessage(), Toast.LENGTH_SHORT).show();
progressBar.setVisibility(View.GONE);
}
}) {
/**
* Passing user parameters to our server
* @return
*/
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("name", name);
params.put("email", email);
params.put("mobile", mobile);
//Log.e(TAG, "Posting params: " + params.toString());
return params;
}
};
// Adding request to request queue
MyApplication.getInstance().addToRequestQueue(strReq);
}
记录是：
