Android subscription purchase AccountHold is null

I am using official google example code for user subscription play-billing-sample. I get nullpointexception on checking the account hold when switching google accounts (my phone has two google accounts registered as test accounts to test the purchases).
I log into the first account without any problems and purchase basic or premium subscriptions
when I switch to the second account, I get the error below:

I don't understand it why I have to get NPE. Or if we get if from the server, why don't I get it with the first account (I even tested putting the purchase on pause for the first account) and it works.
PS. Initially in my play console, Account hold feature was not active, but later on, I activated the account hold and account pause feature. But still I get the same error just after switching to the second google account.

Every time when Java uses Boolean object in if statement it unwraps it to primitive which is boolean type with Boolean.booleanValue() method.
To fix the issue you have to change isAccountHold and isEntitlementActive types from Boolean to boolean.
If those fields have to be Boolean type then check them for null before:
public static boolean isAccountHold(SubscriptionStatus subscription) {
return subscription != null &&
(subscription.isEntitlementActive == null || !subscription.isEntitlementActive) &&
(subscription.isAccountHold != null || subscription.isAccountHold) &&
!subscription.subAlreadyOwned;
}

How to remove particular bean object from ArrayList in Java? [duplicate]

This question already has answers here:
When you call remove(object o) on an arraylist, how does it compare objects?
(4 answers)
Closed 8 years ago.
I want to remove particular bean object from ArrayList.
I am using remove and removeAll method for delete the object element from ArrayList, but not remove element.
for example, assume below code,
ArrayList<SystemDetailData> systemDetails = new ArrayList<SystemDetailData>();
SystemDetailData data = new SystemDetailData();
data.setId("1");
data.setName("abc");
data.setHost("192.168.1.2");
systemDetails.add(data);
data = new SystemDetailData();
data.setId("2");
data.setName("asd");
data.setHost("192.168.1.45");
systemDetails.add(data);
System.out.println("Before remove : " + systemDetails);
ArrayList<SystemDetailData> systemDetail = new ArrayList<SystemDetailData>();
SystemDetailData data = new SystemDetailData();
data.setId("1");
data.setName("abc");
data.setHost("192.168.1.2");
systemDetail.add(data);
System.out.println("Old data :" + systemDetail);
//Remove object from arraylist - method1
systemDetails.removeAll(systemDetail);
//Remove object from arraylist - method2
systemDetails.removeAll(systemDetail.getId());
systemDetails.removeAll(systemDetail.getName());
systemDetails.removeAll(systemDetail.getHost());
System.out.println("After remove : "+systemDetails);
Bean Class :
public class SystemDetailData extends BusinessData {
/**
*
*/
private static final long serialVersionUID = 1L;
private static final String DOMAIN_NAME = "domainName";
private static final String HOST_NAME = "hostName";
private static final String USER_NAME = "userName";
private static final String PASSWORD = "password";
private static final String INDEX = "index";
private BigInteger index;
private String domainName;
private String hostName;
private String userName;
private String password;
public BigInteger getIndex() {
return (BigInteger) get (INDEX);
}
public void setIndex(BigInteger index) {
set (INDEX, index);
this.index = index;
}
public String getDomainName() {
return (String) get(DOMAIN_NAME).toString();
}
public void setDomainName(String domainName) {
set (DOMAIN_NAME, domainName);
this.domainName = domainName;
}
public String getHostName() {
return (String) get (HOST_NAME);
}
public void setHostName(String hostName) {
set (HOST_NAME, hostName);
this.hostName = hostName;
}
public String getUserName() {
return (String) get (USER_NAME);
}
public void setUserName(String userName) {
set (USER_NAME, userName);
this.userName = userName;
}
public String getPassword() {
return (String) get (PASSWORD);
}
public void setPassword(String password) {
set (PASSWORD, password);
this.password = password;
}
#Override
public String toString() {
return "SystemDetailData [index=" + index + ", domainName="
+ domainName + ", hostName=" + hostName + ", userName="
+ userName + ", password=" + password + "]";
}
#Override
public String getKeyValue() {
String value = "";
if (index != null) {
value = value + "INDEX =" + index + ";";
}
if (domainName != null) {
value = value + "DOMAIN_NAME =" + domainName + ";";
}
if (userName != null) {
value = value + "USER_NAME =" + userName + ";";
}
if (hostName != null) {
value = value + "HOST_NAME =" + hostName + ";";
}
if (password != null) {
value = value + "PASSWORD =" + password + ";";
}
return value;
}
}
I got below output :
Before remove : [SystemDetailData [index=1, Name=abc, host=192.168.1.2], SystemDetailData [index=2, Name=asd, host=192.168.1.45]]
Old data : [SystemDetailData [index=1, Name=abc, host=192.168.1.2]]
After remove : [SystemDetailData [index=1, Name=abc, host=192.168.1.2], SystemDetailData [index=2, Name=asd, host=192.168.1.45]]
I want below output :
After remove : [SystemDetailData [index=2, Name=asd, host=192.168.1.45]]

If the SystemDetailData Class you have to implement hashcode and equals method. To expand my answer, In java when you want to delete an Object from a collection. Java check if the Object you want to delete is in this collection ( if Collection contains an Object which is equals to the one we want to delete). It uses the method equals. So we have to tell (explain) to Java what is for us the same Object: it can have the same name or the same id or another property ( attribute ). This is a reason why we have to implements equals (and hashcode)

Your SystemDetailData class needs to implement an equals method. When you call remove on the ArrayList, the code is doing something like:
ArrayList<SystemDetailData> items;
void remove(SystemDetailData itemToRemove) {
for ( int i = 0; i < items.size() ++i ) {
if ( items.get(i).equals(itemToRemove) ) {
items.remove(i);
break;
}
}
}
he
So unless the equals method returns true for the item you are passing into the remove method and an item in your collection, nothing wil be removed.
You need to decide exactly what the equals method should look like but if, for example, two items are the same if the ids are the same then you could just add a method to SystemDetailData like:
public boolean equals(Object other) {
SystemDetailData otherData = (SystemDetailData)other;
return otherData.getId() == this.getId();
}
Obviously you'll need to add checks for null, the type of other etc. but that should give you an idea of what the method needs to look like.

How to intercept and change sql query dynamically in mybatis

I use mybatis to perform sql queries in my project. I need to intercept sql query before executing to apply some changed dynamically. I've read about #Interseptors like this:
#Intercepts({#Signature(type= Executor.class, method = "query", args = {...})})
public class ExamplePlugin implements Interceptor {
public Object intercept(Invocation invocation) throws Throwable {
return invocation.proceed();
}
public Object plugin(Object target) {
return Plugin.wrap(target, this);
}
public void setProperties(Properties properties) {
}
}
And it really intercepts executions, but there is no way to change sql query since appropriate field is not writable. Should I build new instance of whole object manually to just replace sql query? Where is the right place to intercept query execution to change it dynamically? Thank.

I hope it will help you:
#Intercepts( { #Signature(type = Executor.class, method = "query", args = {
MappedStatement.class, Object.class, RowBounds.class,
ResultHandler.class
})
})
public class SelectCountSqlInterceptor2 implements Interceptor
{
public static String COUNT = "_count";
private static int MAPPED_STATEMENT_INDEX = 0;
private static int PARAMETER_INDEX = 1;

BoundSql boundSql = ms.getBoundSql(parameter);
String sql = ms.getBoundSql(parameter).getSql().trim();
BoundSql newBoundSql = new BoundSql(ms.getConfiguration(),

MappedStatement newMs = copyFromMappedStatement(ms,

if (index != -1)

You may consider using a string template library (eg Velocity, Handlebars, Mustache) to help you
As of to date, there is even MyBatis-Velocity (http://mybatis.github.io/velocity-scripting/) to help you to do scripting for the sql.

Depending on the changes you want to make, you may want to use the dynamic sql feature of mybatis 3
