I can't tell for certain, but it seems like when the main thread is blocked, that the corresponding function doesn't go through... I have a counter that increases everytime I make a call to my addAlarmAtTime(passedTime) function, and the number from the the counter is quite a bit higher than the length of alarms array that I get from getAlarms()...

For example, the counter is 56, when the length of the array that holds the alarms is only 37...

I have to admit to being very confused over the "Plugin should use CordovaInterface.getThreadPool()" message.

The code is already using:

cordova.getThreadPool().execute(new Runnable() {
                    @Override
                    public void run() {
                                             .... 
                    }
                });

This seems to match the example shown in the docs -> http://docs.phonegap.com/en/2.3.0/guide_plugin-development_android_index.md.html

I've seen the warning on my Background Service as well (open issue -> Red-Folder/Cordova-Plugin-BackgroundService#19) - but never understood why it is occurring.

I'll have a fresh look.

Further notes to myself;

Taken from https://github.com/apache/cordova-android/blob/master/framework/src/org/apache/cordova/PluginManager.java:

private static final int SLOW_EXEC_WARNING_THRESHOLD = Debug.isDebuggerConnected() ? 60 : 16;

....

            long pluginStartTime = System.currentTimeMillis();
            boolean wasValidAction = plugin.execute(action, rawArgs, callbackContext);
            long duration = System.currentTimeMillis() - pluginStartTime;

            if (duration > SLOW_EXEC_WARNING_THRESHOLD) {
                Log.w(TAG, "THREAD WARNING: exec() call to " + service + "." + action + " blocked the main thread for " + duration + "ms. Plugin should use CordovaInterface.getThreadPool().");
            }

Within CordovaActivity.java, the getThreadPool as :

    public ExecutorService getThreadPool() {
        return threadPool;
    }

"threadPool" is defined as java.util.concurrent.Executors.newCachedThreadPool()

I believe I've made a fundamental mistake with how I'm using the Runnable class.

While I'm defining the logic with new Runnable.run() (which in then passed to the getThreadPool().execute()), that code if making reference to lots of methods of the parent class (the plugin) - which I suspect is causing locking issues.

I think I need to be creating a new class (SchedulerLogic) which extends Runnable and move the run and logic code into that class. Then on getThreadPool().execute() pass a new SchedulerLogic.

I probably also need to put some syncronization round any dal amendment (addAlarm, updateAlarm & cancelAlarm) and release on save - may try to push this in to the DAL to ensure that its atomic. Likely to need to employ some level of dispose ... example code:

bool disposed;
public void Dispose(){
    Dispose(true);
    GC.SuppressFinalize(this); // tell GC not to call Finalizer() for this object
}

~MyObject(){
    Dispose(false);
}

void Dispose(bool manualDisposing){
    if(!disposed){
        disposed = true;
        if(manualDisposing)
           ... // call Dispose on all IDisposable fields
        ... // dispose all native resources
    }
}

First job will be to create a repeatable test - probably a loop which creates 50 alarms should do it.

[Another note to myself]
Need to review how to make the DAL thread safe

Take a look at Katzer's code for a local notification plugin. When I originally used the plugin it suffered from the same problem, then in an update he documented a fix and it seemed to solve the problem for the most part (instead of nearly a third of added notifications blocking the main thread, I might get 1 or 2 when adding 50-100 notifications).
