After further research and many dead ends, I was able to get my C ++ code to work on Cordova. I am answering here to document some of my problems and provide some good resources for others trying to do the same.
Cordova plugin development
A good tutorial that explains each part of the plugin better than the official documentation: https://blogs.oracle.com/mobile/entry/introduction_to_custom_cordova_plugin
My biggest problem with this part of the development was that removing the Cordova plugin in VS 2015 does crappy work and sometimes searches for files in the wrong places. Be careful with this if you need to modify the XML file of your plugin.
Communication with C ++
VS, .so ( → android). , ARM, x86 . .so /libs/armeabi, .java loadLibrary().
.java :
package com.example.plugin.cpp;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import org.apache.cordova.CordovaArgs;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CordovaWebView;
import org.apache.cordova.CordovaInterface;
import org.apache.cordova.PluginResult;
import org.json.JSONObject;
import org.json.JSONArray;
import org.json.JSONException;
public class Cpp extends CordovaPlugin {
public static final String ACTION_SEVEN = "seven";
public Cpp() { }
@Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) {
if (ACTION_SEVEN.equals(action)) {
alert("Message from Java", "Grabbed the number " + get7() + " from C++", "dismiss", callbackContext);
callbackContext.success();
return true;
}
return false;
}
private synchronized void alert(final String title,
final String message,
final String buttonLabel,
final CallbackContext callbackContext) {
new AlertDialog.Builder(cordova.getActivity())
.setTitle(title)
.setMessage(message)
.setCancelable(false)
.setNeutralButton(buttonLabel, new AlertDialog.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int which) {
dialogInterface.dismiss();
callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.OK, 0));
}
})
.create()
.show();
}
public native int get7();
static {
System.loadLibrary("CppLibrary");
}
}
C++:
CppLibrary.cpp:
#include "CppLibrary.h"
extern "C" {
JNIEXPORT int JNICALL Java_org_example_plugin_cpp_Cpp_get7(JNIEnv* env, jobject thiz)
{
return 7;
}
}
Cpp.h:
#pragma once
extern "C" {
JNIEXPORT int JNICALL Java_org_example_plugin_cpp_Cpp_get7(JNIEnv* env, jobject thiz);
}
