Android java.lang.IllegalMonitorStateException: object not locked by thread before wait()

Question

I define a global static object as a synchronization lock.

public static Object ConfirmationSynObj = new Object();

The following function i

Answer 1

 new Thread(new Runnable() {

            @Override
            public void run() {

Above thread is not owning lock on ConfirmationSynObj object hence throwing IllegalMonitorStateException

Use one more synchronized block inside run method

           @Override
            public void run() {
            synchronized (Config.ConfirmationSynObj) {
                //this is a http request
                appSignInfo = getAPKSignature(context, pkinfo.packageName);
                Config.ConfirmationSynObj.notify();
               }
            }
