I can run my application with an account. But account info seems like null on profile page. and so the app crash because of null value. I searched that there was a bug with butterknife. I am new to android. please help me to solve this problem. first I had an error NPE and I saw that id is null.
my fragment_account.xml is:

my AccountFragment.java is:
@BindView(R.id.user_info)
protected TextView userInfo;
my logcat is:
java.lang.NullPointerException: Attempt to invoke virtual method 'com.applogist.filomotive.network.responese.model.user.UserModel com.applogist.filomotive.network.responese.model.login.LoginModel.getUserInfo()' on a null object reference
my profil page with "üye no..."Normally the first and last name should appear.
my LoginModel.java is:
public class LoginModel extends BaseModel {
@SerializedName("LoginKey")
private String loginKey;
@SerializedName("LogoutTime")
private Date logoutTime;
@SerializedName("UserInfo")
private UserModel userInfo;
public String getLoginKey() {
return loginKey;
}
public void setLoginKey(String loginKey) {
this.loginKey = loginKey;
}
public Date getLogoutTime() {
return logoutTime;
}
public void setLogoutTime(Date logoutTime) {
this.logoutTime = logoutTime;
}
public UserModel getUserInfo() {
return userInfo;
}
public void setUserInfo(UserModel userInfo) {
this.userInfo = userInfo;
}
@Override
public String toString() {
return "LoginModel{" +
"loginKey='" + loginKey + '\'' +
", logoutTime=" + logoutTime +
", userInfo=" + userInfo +
'}';
}
}
my model cannot receive userInfo.
private UserModel userInfo = new UserModel();
in LoginModel.java object creation is required as above. sorry for my poor info about this question
