I am running my Angular2/Ionic2 app under Android 4.4.4 on a real device; however, I am getting a white black screen, after inspecting the device I got the following error:
Uncaught Cannot resolve all parameters for 'App'(?, ?, ?). Make sure that all the parameters are decorated with Inject or have valid type annotations and that 'App' is decorated with Injectable.
I've tried to run it on Android 5.1, it worked fine!
I've read some posts saying that in order to hide the error, I should use crosswalk, but I believe that Ionic2 support Android versions >= 4.4.4 So it should work without crosswalk!

I'm having a strange problom where my cordova app on android fails to load js/css files where if I run in the browser It does not.
from remote debugging I got these error messages:
file:///css/all.css Failed to load resource: net::ERR_FILE_NOT_FOUND
file:///js/shims.js Failed to load resource: net::ERR_FILE_NOT_FOUND

For anyone interested in the future, I solved this problem, as I'm using angular 2 in my app, I defined as you can see in my code snippet a base url for my app :
<base href="/">
This becomes a problem in cordova and should be deleted for an android/ios app.
if css and js folder are in same level as index.html you should link them like this :-
<link href="css/android/prelogin.css" rel="stylesheet">
<script type="text/javascript" src="cordova.js"></script>
<script src="scripts/lib/jquery/jquery.1.9.1.js"></script>
<script src="scripts/lib/jquery/jquery.mobile-1.3.2.js"></script>

I load my index.html from my android app which is built using Cordova. I have included my jquery file correctly, but I still get the error uncaught reference error jQuery is not defined.

I get the error Uncaught Reference error jQuery is not defined from document ready function. I get the same error from mydevice.js file.
mydevice.js file looks like below
jQuery(document).ready(function(){

});
My java code to launch index.html looks like below
public class AppActivity extends CordovaActivity
{
public static final String INDEX_FILE_PATH = "file:///android_asset/www/index.html";
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// super.loadUrlTimeoutValue = 1000 * 60;
super.init();
// super.loadUrl(INDEX_FILE_PATH);
loadUrl(launchUrl);
}
}
I have gone through this link uncaught reference error. Not sure what I am missing?
I found out, I get this error when I am using a proxy on my WIFI in android simulator. If I don't use that proxy, I don't get this error.
If I remove the proxy I had added, this works fine without any error. Looks like a cross-domain issue.

I suspect it could be a problem with the JavaScript engine, for older phones which have older JS engines you can use a Polyfill downloaded from https://cdn.polyfill.io/v2/docs/, which I used it to sort out this error which I saw when running adb logcat with my phone connected and opened the app :
Uncaught TypeError: Object function Object() { [native code] } has no method 'assign
Run adb logcat to see what the error is in your case, you probably won't see it from the Chrome console
I was trying to build a sample app through phonegap(3.7)(build.phonegap.com) made using polymer(0.5).The build was successful.
However, when I installed the app in my android(v4.4+) device, I could not see the polymer element(I just inserted a <paper-checkbox> to test). All other simple HTML elements were rendered normally.
I read about the android webview support of HTML import, so I tried to vulcanize the index.html, but it didn't help. But I can see the polymer element by running the python SimpleHTTPServer on my laptop, and there's no error in the browser javascript console (other than failed to load resource.. cordova.js).
Here's the index.html (non-vulcanized version) I have created:

Is there anything I'm missing?? Please help. Thanks!

I saw this issue in from a library that uses Polymer in github. It says its not supporting devices below Android 4.4 (Probably). I am trying to integrate with Cordova Crosswalk and see if I can get it to work. The stock browsers from lower version of Android before 4.4 are really crappy. I am really having hard time making my web apps work on lower-end devices.
Some issues like abysmally slow js performance, exceptions, bugs are rampant on older webviews. What we can do for now is to wrap our app using a different webview such as using Cordova with Crosswalk as also suggested from the link I provided above.
Hope this helps.
I am developing an android app using phonegap. I have added google-play-services library project successfully. Now I want to integrate AdMob for advertising purpose. I have followed these steps https://developers.google.com/mobile-ads-sdk/docs/. My project is built and run successfully but ads are not showing there.
I have added AdMob Cordova Plugin and the SCRIPT in index.html. Here is my index.html

Can anyone tell me what actually I have missed here? I think my project is not finding the plugin anyhow. But I have added the the plugin in config.xml also. Then whats wrong? Please reply!!
No need to add separate sdk's for both GCM and AdMob, google play services contains both sdk you can use it. Use latest android google play services that contains both sdk packages.
You are doing with old way, actually, google have declared updated google_play_services library, which contains all your individual libraries in it. So dont use individual libs, just get updated google_play_service lib and go on...!!!
Ok my problem solved. The problem was not related to google-play-sevices configuration. So I can't accept any answer. Thank you everyone to help me. At least I got the surety that I was not wrong in google-play-services and admob configuration.
