如何通过凌空或asynctask或Advance网络库在移动数据上运行Android应用？我尝试了很多解决方案，但是我的Android应用无法在移动数据上运行。我已经提高了凌空抽射的超时时间，但无法解决我的问题。
在下面用排球库显示我的所有代码，但是用此代码也无法解决我的问题。
firstName = etFirstName.getText().toString();
lastName = etLastName.getText().toString();
email = etEmail.getText().toString();
password = etPassword.getText().toString();
if (TextUtils.isEmpty(firstName)) {
etFirstName.setError("Required");
etFirstName.requestFocus();
} else if (TextUtils.isEmpty(lastName)) {
etLastName.setError("Required");
etLastName.requestFocus();
} else if (TextUtils.isEmpty(email)) {
etEmail.setError("Required");
etEmail.requestFocus();
} else if (!Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
etEmail.setError("invalid email");
etEmail.requestFocus();
} else if (TextUtils.isEmpty(password)) {
etPassword.setError("Required");
etPassword.requestFocus();
} else {
etFirstName.setError(null);
etLastName.setError(null);
etEmail.setError(null);
etPassword.setError(null);

在某些设备上使用移动数据时，发送的数据长度受到限制，因此请尽量减少数据量。
