Error when receiving Push in Android

[carliskisantiago]

Hello, I'm developing an app using Pushwoosh but now i'm facing an error with Android (iOS works fine). Sometimes when I receive a push using the remote API my app crashes and I get this error log (I'm attaching the complete error log) log.txt . I'm using Titanium SDK 4.1.0. Thanks in advance. Santiago.

Could you please make sure you are calling push callbacks on a main thread?

Try to wrap them in setTimeout as outlined here: http://docs.pushwoosh.com/docs/appcelerator-titanium

pushnotifications.pushNotificationsRegister({
    "pw_appid": "ENTER_PUSHWOOSH_APPID_HERE",
    success:function(e)
    {
        setTimeout(function() {
            Ti.API.info('JS registration success event: ' + e.registrationId);
        }, 0);
    },
    error:function(e)
    {
        setTimeout(function() {
            Ti.API.error("Error during registration: "+e.error);
        }, 0);
    },
    callback:function(e) // called when a push notification is received
    {
        setTimeout(function() {
            //push notifications title: e.data.aps.alert
            Ti.API.info('JS message event: ' + JSON.stringify(e.data));
        }, 0);
    }
});

Yes we're calling push callbacks on the main thread and we set the timeouts as you mention. BTW, we are using 2000 ms insted of 0 because that causes more failures. Everything is working OK but sometimes it fails and only using Android, not iOS. We don't know what we can modify to get it working.

Hi,

I've got the response from the Titanium team. It looks like you have to update to the 5.2.x version of Titanium. Appcelerator made a change that I think was the ultimate resolution to the problem. The 4.x line was pretty buggy overall.

Specifically, they now check for null here: https://github.com/appcelerator/titanium_mobile/blob/384775e13e153620194c874699490fe9524ce9d9/android/modules/network/src/java/ti/modules/titanium/network/TiHTTPClient.java#L1214

@shaders thanks for your response, we made that change and we switched to Titanium SDK 5.2.0 but now we are getting a similiar error from other Proxy. I'm attaching the error log again. Every tip will be useful as we're soon to reach launch date. Thanks again :D log.txt
