How to create Android Handler in Java plugin
So, let's say you have a Java plugin, you call into the Java plugin like so
private static readonly AndroidJavaClass m_somePlugin = new AndroidJavaClass("com.unity3d.Plugin.blah.SomePlugin");
using (var unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
{
using (var currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
{
m_somePlugin.CallStatic("onInitialise", currentActivity);
}
}
and it looks something like this
public class SomePlugin
{
static public void onInitialise(final Activity currentActivity)
{
Handler someHandler = new Handler();
}
}
All quite simple. Except it will crash. Creating a Handler is the cause. I'm guessing it's a thread issue.
So the question is, how does one create a handler in a Java plugin? Anyone know?
looks like currentActivity.runOnUiThread may be the way to go. I'll try it and report on here if it is successful.
Best Answer
Yes, the solution to the problem was to use runOnUiThread. So in order to get the above code to not crash SomePlugin should look like so
public class SomePlugin
{
static public void onInitialise(final Activity currentActivity)
{
currentActivity.runOnUiThread(new Runnable() {
Handler someHandler = new Handler(); });
}
}
