Genymotion: "Unfortunately <app> has stopped"

I've created an application in React Native that works fine in iOS. I've copied the code over to the Android portion of it, and separated out the platform-specific components. When I hit a certain component, the app crashes with an "Unfortunately has stopped".
There are no logs, no error in the console, nothing. What do I look for and where can I look? Logs? Somewhere in code?
In ~/genymotion-log/Google Nexus 6<...>-logcat.txt, I see the following:

No fix, but the reason is I'm pushing too much data from the server to the client. Once I ran adb logcat, I got this:
java.lang.OutOfMemoryError: Failed to allocate a 2470012 byte allocation with 48508 free bytes and 47KB until OOM.
Turns out I'm pushing my images over and over to the client until it breaks. iOS can handle it but RN can't.

setSupportActionBar() Makes my app disfunction

For some reason when i put the line setSupportActionBar(MyToolBarVariable)... It goes on to my Genymotion Emulator.. But when it opens the app, it says :
Unfourtuanetly "AppName" has Stoped
But if i delete the setSupportActionBar() Everything works fine... Whats the problem here.. Im going to post MainActivity.java file.. If you need to see others please tell me so below. Thanks for helping!
package com.example.amanuel.zoo4;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
setContentView(R.layout.activity_main);

MVVMCross 3.5.1 and xamarin android does not work

I have a question: is there somebody that use MVVMCross 3.5.1 with Api level android 21 and xamarin studio 5.9.3? I have a problem: I reference mvvmcross in an android app. I have a splashscreen and a firstview. When I tried to start with emulator I don't have any problem with level 15 emulator but when I tried it with the last version (Api 21) the app after splashscreen is closed without any error (not open the firstview).
Is there a solution?
UPDATE
I tried with logcat. In the following I attached the log:

UPDATE 2
The bind does not work. Inside the view..
UPDATE 3
I put the code in this repo:
https://onedrive.live.com/redir?resid=1E563B1D1AD8A1C!15847&authkey=!AII01sfuzToQiUQ&ithint=file%2czip
I used this configuration for the test:
1. Nexus 5,
2. Android 5.0-API Level 21,
3. CPU/ABI, I have chosen Google APIs Intel Atom(x86_64),
4. Use Host GPU.
UPDATE 4
new link for code: http://1drv.ms/1MZWf45
Thanks
Alessandro

I found the problem. The problem was the emulator. I tried to change the configuration and now run without problem.
Thanks

android not honoring trigger.io's tabs.openWithOptions for server side redirect

I've got some basic trigger.io code to open a modal dialog for oauth2 authentication:
var url_auth = "http://10.0.0.70/oauth2/authorize";
var oauth_client_id = "123";
var oauth_redirect_uri = "http://done.com/oauth2/complete";
forge.tabs.openWithOptions({
url: url_auth + "?response_type=token&client_id="+ oauth_client_id + "&redirect_url=" + oauth_redirect_uri,
pattern: oauth_redirect_uri + "*",
title: "Authorizing"
}, function(data) { ... });
When the user isn't authenticated, the server redirects to http://10.0.0.70/users to present a login form.
Running the code in an iOS6 simulator yields the correct result:
open modal dialog
server redirects to login form, presented within the dialog
user can authenticate
server redirects to oauth_redirect_uri which trigger catches and closes the dialog
When I run in an android simulator, the initial page is loaded, but then the app crashes.
I see the /oauth2/authorize url being processed on the server
all I see in the debug dialog is "subView load http://10.0.0.70:3000/users"
The more details around the error are (nothing after this in logs):
[DEBUG] Native call tabs.open with task.params: {"url":"http://10.0.0.70:3000/oauth2/authorize?response_type=token&client_id=123&redirect_url=http://www.diveboatbuddy.com/oauth2/complete","pattern":"^http://www.diveboatbuddy.com/oauth2/complete.*$","title":"Authorizing"}
[INFO] Displaying modal view.
[DEBUG] Returned: {"content":null,"callid":"0F7BA94D-08AD-439D-B44F-80BB22540CD4","status":"success"}

[INFO] subView load http://10.0.0.70:3000/users
So it looks like the server has redirected correctly, but the trigger.io app isn't rendering the new server page.
adb logcat output of the problem:

Has anyone come across this issue. Is there a work around or a bug?

This was fixed in v1.4.34 of the Trigger.io platform: http://docs.trigger.io/en/v1.4/release-notes.html#v1-4-34.

Android ListView throwning NullPointerException

I have an android app that gets an HTTP response from a webservice, which I process into an array of strings. I than try to display those strings in a ListView. they do not need to be clicked for any action, just displayed and be scroll-able.
When ran, Everything gets done ok, but when I try to scroll down beyond the amount of items that i have to show (because there are no more strings to display on list) I get a NullPointerException. Obviously I must be doing something wrong.
I don't quite get it. I've written a similar example as a test and it works just fine. the list in the example just scrolls and stops when there are no more items to show. The only difference I can think of is that on the original app the array gets created on a thread, and than the thread runs a runnable using a handler to display the list on the gui.
when the thread that fetches the strings and orders them to the array to display finishes, he runs this code using a handler:
scoreList = (ListView) findViewById(R.id.scorelist);
ArrayAdapter<String> myAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,scoreResult);
scoreList.setAdapter(myAdapter);
than the app crashes when trying to scroll lower than the bottom. this is the error from adb logcat:

When ran, Everything gets done ok, but when I try to scroll down
beyond the amount of items that i have to show (because there are no
more strings to display on list) I get a NullPointerException.
Obviously I must be doing something wrong.
That exception comes from having null values in the list/array(scoreResult) that you pass to the ArrayAdapter. This is because the ArrayAdapter will call, by default,(in it's getView method which is responsible for building the list's rows) the toString method on each item from the data list if the type of that item isn't a CharSequence(you have String), to obtain a text representation of that item to show in the row.
So check the scoreResult list/array and make sure you don't have null values in it. I see you speak of an array, make sure the array is just as big as it needs for the data, if it's bigger than the data you'll have null values at its end.

pls check what is there, somethig not good.
NullPointerException it is the beginner programmer sign: it doesn't verify the parameters and he write multiple statements in 1 line. In this case I would check the scoreResult to not be empty, but at least not null
