around this issue I am not completely sure how running multiple queries in a single query statement works (if it works) because I typically do transactions by running each query separately in a prepare/execute statement. The transaction will still queue up all the changes until commit/rollback as expected. According to this SO answer it appears to work, however the example is not binding values and so that might be another issue.
I would suggest just splitting up the queries into multiple prepare/bind/execute statements and it should work as expected.

I wish this helpful for you If you want to stop a thread instead of using normal thread to do background jobs use Android sdk's AsyncTask, there you can find a cancel().

Why doesnt throwing an XAException from a XAResource still allow an transaction commit to succeed?

should help you out TM behaviour depends not just on the existence of an XAException but on the XAException error code. Any of the (spec compliant) XA_RB∗ codes thrown from end should cause a rollback.

How do I interrupt Java code that doesnt finish and doesnt throw ThreadInterruptionException

By : Isaias Alves

hope this fix your issue I would try Thread.interrupt() as even though the interrupted exception isn't thrown it doesn't necessarily mean that the 3rd party library doesn't handle it correctly in some other way. If that doesn't work then I would consider Thread.stop() even though it is depricated in the hopes that the library's design can handle sudden termination and doesn't end up in an inconsistent state (due to the transactional nature in which you are using it, I doubt there are many shared objects to get corrupted). Thread.stop() will cause the event to stop immediately and throw a ThreadDeath exception no matter what it is doing and it was deprecated by Sun due to the chance of leaving shared objects in an unknown and inconsistent state.

Why Java method doesnt throw exception in test class?

Does that help A far more concise example works just fine. I disagree that test should inherit from Mammal, but left it in there for my example:
Mammal.java:

code :

public class Mammal {
int health =500;
  public void takeDamage(int damage) throws Exception{
    if(damage < 1) {
      throw new Exception("Damage cant be negative!");
    }
    else this.health -= damage;
  }

public class MTest extends Mammal {
public static void main(String args[]) {
    Mammal m = new Mammal();
    try {
        m.takeDamage(-100);
    } catch(Exception e) {
        System.out.println("Exception");
    }
}

Android Mediaplayer doesnt throw IO exception If file not available at the link

I wish this helpful for you If you are playing with remote media resources, I'd recommend other mediaPlayer implementation like google/ExoPlayer2.
The retry count of Android default player is 10. There is no error handling on HTTP 404 response.

code :

struct NuCachedSource2 : public DataSource {

...
enum {
    kMaxNumRetries = 10,
};

      if (retryAction == DONT_RETRY_FATAL) {
        fatalError = currentError;
      } else if (retryAction != DONT_RETRY) { // DONT_RETRY = 2
        errorCount = retryAction == RETRY_RESET_ERROR_COUNT ? 1 : errorCount + 1;
        start(getRetryDelayMillis());
      }
