当推送到达时，将cordova应用程序带到前台

Question

I have app up and running. Push notifications are working ok. I need that when push arrives, bring app to foreground, on Android. So, what I found is this piece of code:

Intent toLaunch = new Intent(getApplicationContext(), MainActivity.class);

toLaunch.setAction("android.intent.action.MAIN");
toLaunch.addCategory("android.intent.category.LAUNCHER");

Taken from this question: Bring application to front after user clicks on home button

I am trying to put this code in GCMIntentService.java from cordova push plugin. No matter where I put it, on compile i always get this error:

/appdir/android/src/com/plugin/gcm/GCMIntentService.java:94: error: cannot find symbol
Intent toLaunch = new Intent(getApplicationContext(), MainActivity.class);
                                                      ^
symbol:   class MainActivity
location: class GCMIntentService

Any ideas how to access this "MainActivity.class" from cordova plugin .java file?

Answer 1

The java compiler is telling you that it doesn't know what MainActivity.class is while compiling GCMIntentService.java . You must import MainActivity class from the package where it is defined eg if the package is called cordovaExample then at the top of GCMIntentService.java put

import cordovaExample.MainActivity;

and the class must be declared public

package cordova;

public class MainActivity {

Answer 2

Here is what I did, Changes on GMCIntentService.java file which worked great for me.

import com.package.app.*;


@Override
        protected void onMessage(Context context, Intent intent) {
            Log.d(TAG, "onMessage - context: " + context);

    // Extract the payload from the message
    Bundle extras = intent.getExtras();
    if (extras != null)
    {
        // if we are in the foreground, just surface the payload, else post it to the statusbar
        if (PushPlugin.isInForeground()) {
            extras.putBoolean("foreground", true);
            PushPlugin.sendExtras(extras);
        }
        else {
            extras.putBoolean("foreground", false);

            Log.d(TAG, "force launch event");
            Intent wintent = new Intent(context, MainActivity.class);
            wintent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED | Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(wintent);

            // Send a notification if there is a message
            if (extras.getString("message") != null && extras.getString("message").length() != 0) {
                createNotification(context, extras);
                PushPlugin.sendExtras(extras);
            }
        }
    }
}
