Callback From Activity On Cordova

I have an activity Called 'Signature' and i call it from CordovaPlugin; Plugin.java public boolean execute(String action, JSONArray args, CallbackContext callbackContex

Solution 1:

First of all there was some code missing(return-statement for execute-method) and you have to tell android/cordova-plugin to wait until there is a result sent back to your webview-app by using NO_RESULT and setKeepCallback of PluginResult otherwise cordova/android expects to get an result as soon as execute-method has finished:

Plugin.java:

publicbooleanexecute(String action, JSONArray args,
            CallbackContext callbackContext)throws JSONException
    {

    PluginResultr=newPluginResult(PluginResult.Status.NO_RESULT);
    r.setKeepCallback(true);
    callbackContext.sendPluginResult(r);

    Intenti=newIntent(context, Signature.class);
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    cordova.startActivityForResult(this,i,90);

    returntrue;

}

publicvoidonActivityResult(int requestCode, int resultCode, Intent intent){
    // here is your former code
    ...
    ...
    // at last call sendPluginResult this.callbackContext.sendPluginResult(newPluginResult(PluginResult.Status.OK, result.toString()));

    // when there is no direct result form your execute-method use sendPluginResult because most plugins I saw and made recently (Reminder) prefer sendPluginResult to success/error// this.callbackContext.success(result.toString());
}

Have an example here(for your plugin class) and here(for your signature class).

And one of mine: here and here.
