How to Call a Custom Module Android Activity from PMC plugin 8.4.3
We recently upgraded from 8.2.7 to 8.4.3 .With the documentation we are able to call the methods from custom module .our requirement is to integrate with third party android module we use for scanning .With the upgrade Android devkit has changed so sdk classes also have changed .What i am looking is how to get the current Activity context and call an Android custom module Activity from a plugin method .
Can any one suggest the methods or sample code that can be used.

Thanks for the response!
I am able to call plugin module and do basic things .Where I am stuck is calling another android activity from within this plugin KT file .Previous versions plugin file used to have a context object which is used to call another Activity.
we have scanbot API which is a custom android module built in kotlin so we are trying to call the scanbot activity from webviewplugin.Grey area is how to preprare an Intent and call this other activity with out having access to Android Context object.

You can get a context out of the webview that is available in the plugin class. And for starting an activity (for result, I assume) you can use our Results.startActivityForResult()
Please refer to the example below for how it's used

val dataToSend = "someData"
intent.putExtra(OtherActivity.REPORT_EXTRA, dataToSend)
scope.launch {
val result = Results.startActivityForResult(it, intent)
if (result.isSuccessful()) {
val data = result.data?.extras?.getString(OtherActivity.REPORT_EXTRA) ?: run {
promise.reject(JavaScriptError("Missing result data"))
return@launch
}
promise.resolve(JavaScriptValue(data))
} else {
PMCLog.d("ReportingPlugin", "Unsuccessful result")
promise.reject(JavaScriptError("Activity cancelled"))
}
}
}
}
override fun onDestroy() {
super.onDestroy()
job.cancel()
}
companion object {
internal const val PLUGIN_NAME = "reporting"
}
}

Very much appreciate the response Radoslaw.
I am using the same code as above no compilation errors but when i execute the method in the plug in which i am calling ScanbotActivity . app is just crashing without giving much information .Any pointers to look .
look at the code below
@JavaScriptAPI
fun openCamera(options: JavaScriptValue, promise: JavaScriptPromise) {
webView?.context?.let {
val intent = Intent(it, ScanbotActivity::class.java)
val dataToSend = "someData"
intent.putExtra(ScanbotActivity.REPORT_EXTRA, dataToSend)
scope.launch {
val result = Results.startActivityForResult(it, intent)
if (result.isSuccessful()) {
val data = result.data?.extras?.getString(ScanbotActivity.REPORT_EXTRA) ?: run {
promise.reject(JavaScriptError("Missing result data"))
return@launch
}
promise.resolve(JavaScriptValue(data))
} else {
PMCLog.d("ReportingPlugin", "Unsuccessful result")
promise.reject(JavaScriptError("Activity cancelled"))
}
}
}

Thanks Mateusz for publishing article on new Client modules.
But, I am not seeing any documentation related to "How to Migrate Existing Custom modules compiled in Mobile Client 7.41 into New mobile client 8.X"
As i see clear difference in the way we implement older versions and newer version.
Will u be able to provide any documentation how easily migrate these modules to newer versions, as we already have hte project code in place. Pega Should not force developer to develop from new as new Custom Module.
Appreciate your help.
