Hi I'm trying to connect to a Chromecast using the Google Cast SDK on a Mac running macOS 10.15.4 and Xcode version 11.4.1 (11E503a) and getting the error:
nw_resolver_start_query_timer_block_invoke [C1] Query fired: did not receive both families in time for 8c3a638c-89a9-b15b-a9e1-6826acf9ee64.local.:8009
In Xcode when trying to connect to a Chromecast. I have done some research and only found this thread How to fix "nw_connection_receive_internal_block_invoke" (console). The error seems related to that the connection to the Chromecast is not over https but have not had any luck trying to allow insecure traffic as a test to see if that solved the problem.
I know that there is not much to go on besides the error code but could not find any related question.
Some things on Chromecast require https; others work over localhost. To check whether Chromecast-on-localhost is the source of the problem, try connecting to Chromecast's default receiver (not your own custom receiver) and streaming your media from public urls, such as those included in the Chromecast iOS codelab. If that doesn't make the errors go away, you need to look elsewhere.
For more detail about when Chromecast requires localhost, see this answer.
I have made a small AndroidTV app that can query a rest api and present the content that it returns. This works without any issues when I am running the app on my Nexus Player with AndroidTV 7 (API 25).
To be able to work on the app, when I'm commuting I would like to be able to develop using the AndroidTV emulator. But when I run my app in the emulator I cannot access my api endpoints.
The emulator does have internet connectivity. In the AndroidTV emulator the "Videos" leanback sample is pre-installed. And that can access the internet and fetch the images from their endpoints.
The code I'm using currently looks like this:
final URL url1;
HttpURLConnection urlConnection = null;
try {
url1 = new URL(url);
urlConnection = (HttpURLConnection) url1.openConnection();
urlConnection.setUseCaches(true);
urlConnection.addRequestProperty("Cache-Control", "only-if-cached");
int maxStale = 60 * 60 * 10; // tolerate stale time in seconds
urlConnection.addRequestProperty("Cache-Control", "max-stale=" + maxStale);
return urlConnection.getInputStream();
} finally {...}
If I use the Google Videos sample resource URL's as input to the above code, I am able to fetch their resources, also when run in the emulator.
Requesting data from my own rest endpoint (also publicly available on the internet) gives a FileNotFoundException.
The urls that cause the exception can be access from my host machine without any problems.
One of the sample resources from the Videos leanback sample is this one:
http://commondatastorage.googleapis.com/android-tv/Sample%20videos/Demo%20Slam/Google%20Demo%20Slam_%20Extra%20Spicy/bg.jpg
The code above can fetch this resource without any problems both when running on the Nexus Player, and in the Emulator.
But it seems as though I cannot fetch resources from other domains than the googleapis.com domain.
I have checked and updated all Android tools to the latest versions. Including platform tools and system images.
I have also tried deleting all AVDs I had that might be outdated and created new ones - but no success.
I am starting the AVD with the "-dns-server 8.8.8.8,8.8.4.4" argument so that it should be able to do DNS lookups.
I might be mistaken, but it seems like the googleapis.com addresses have been whitelisted in the emulator somehow.
Is there some place or setting where I can whitelist my own URL, or similar way that I can get access to my api on the internet when running in the emulator?
Try to check the proxy on emulator settings. Another common issue: check the date/time of emulator. If old, then SSL will not work.
I forgot to update this.
It turned out to be a bug in the Android Emulator. Google fixed it about 6 months after the issue was reported. Or I guess they fixed it earlier than that, but it was not released to the public until 6 months later.
I wanted to use Instagram on my computer, so I decided to use an Android Virtual Device for that task.
I downloaded the Android SDK and the newest apk for instagram for my computer.
Then I created a new AVD and ran it. After it was booted, I installed the instagram apk using adb install instagram.apk.
It installed smoothly and after clicking the app, it started.
Now here's my problem: From there on nothing works.
When I try to login and I press the login button, nothing happens like there would be no internet connection.
Browsers and other apps using an internet connection work just fine, just instagram doesn't work.
How can I fix this?
I think it has something to do that the android Emulator can't really handle a global proxy.
Therefore hostnames get resolved directly to their IP which violates HTTP 1.1 standarts and the request doesn't get send properly.
To fix this, it is needed to change it so the hostname gets send instead of the IP.
You should try creating an AVD with different settings. More RAM and allowing GPU emulation is a good idea. If you insist on using an AVD and you have an appropriate intel CPU then you can make the emulator run much faster by following these steps. They are a bit complicated, but worth it if you want the emulator to run quicker.
I typically try to avoid using the Android emulator while I am developing apps. It has its uses, but it tends to be slow and doesn't have all of the capabilities of actual devices.
As an alternative to using an AVD, I would recommend downloading and installing BlueStacks. BluesStacks was written from the ground up to allow running Android apps on your Windows PC or Mac. I have used it before and it does a great job. Much better than an AVD.
Try visual studio emulator for android. Instagram works on it with enabled and connected wifi. This emulator works better than BlueStacks.
While working with my app that require network access...
The Android 2.2 emulator's network connection stop working...
The net was working properly but after some time it did not respond on emulator,
while it was working f9 on my system...
I have cross checked the net connections and restarted with the emulator(even created a new avd ). But the problem remains same my net is not working on emulator..
I have also checked the connection with F8 key on emulator...
My app manifest net permission is enabled....
Finally After all I have myself found the solution of to the problem:
It's very common problem that must have been faced by most of android developers....
Recently, while developing an Android Application, I was faced with a situation that wasted 2 hours of my time. The issue was simple, my app was not able to access internet from the Android Emulator.
Initially I thought fixing the issue should have been straight forward, but life is not always that simple.
So what was the real issue because of which my app was not able to access internet? There are multiple reasons because of which this issue could occur. Hence, I decided to document my findings so that other could benefit from it.
There are two main symptoms of no internet connection on android emulator.....
**Only your app is not able to access the internet
**None of the apps are able to access the internet
Lets look at what are the reasons behind each of them.
Only your app is not able to access the internet
If only your app is not able to access the internet on the emulator, check if any other apps are able to access the internet or not. For e.g. you could open up the browser application, visit http://news.google.com/. If the page opens up correctly then problem lies in your app itself and its simple to fix.
Basically, your app needs the Permission to access the internet. This can be done by adding the following line just before the end of tag in AndroidManifest.xml file of your application.
Compile and re-install the app in the emulator and try to access the internet from your app. It should work!
What is the use of uses-permission tag:
Android application can request certain permissions so that they can function properly. Some examples of permissions are, get users location, make a call, access the internet etc. App has to explicitly specify this in the AndroidManifest.xml.
When end users install such an app on their device, the android OS will notify the user that, app is requesting certain permissions. If users are fine with that, then only the app will be installed. Else users can deny the permission and the app will not be installed.
This mechanism is Androids way of implementing security and users privacy!
This is the more tricky situation:
None of the apps are able to access the internet
Now this situation is tricky. There are two reasons because of which this could happen
Proxy server is not configured on the emulator
Incorrect DNS used by the emulator
Setting Up the DNS Server:
emulator.exe -avd 'android1.6' -dns-server 8.8.8.8
The android1.6 is your avd name I created an avd with name android1.6
So just replace android1.6 with your avd name.
Run this code in command prompt after setting the path to tools & platform tools of your android sdk
For some reason, I'm no longer able to connect and deploy to my wp7 device. Zune does not show the phone as being connected, despite the fact that it is connected and the phone shows that it's being charged ... and the wpconnect tool gives the following error:
Failed to connect to the device.
Ensure that the device is completely
booted and is connected to the PC.
(0x80070103)
I rebooted the phone, and I've deployed to it before, so it's definitely developer unlocked. I verified that my computer has internet access. Any other troubleshooting thoughts?
Hey, I run into this all the time. Simply restart your phone and connect again. Make sure you plug in and unplug the phone several times, waiting at least a minute if it doesn't work.
In short, it's temperamental, Keep trying.
Make sure that you have switched off WiFi and Bluetooth on your phone.
I have found that I cannot deploy when Wifi and Bluetooth are switched on - even though Zune is syncing music and other content in the usual fashion. The error messages are frustratingly unhelpful!
As a short term workaround try using the Application Deployment utility to deploy the xap file.
I had the same issue. When I changed the Project properties target OS to 7.1 it worked.
I had the same issue. Only restoring to the previous OS version helped me.
Also I would that it usually happens when internet sharing is turned on.
I think I finally found the problem!
When I had this problem a few days ago, I had been charging my phone (Lumia 900) using a faulty charger which keeps on getting disconnected. And now that I've changed the cable and charger, it started working again!
I had the same problem with my previous phone as well (HTC Mozart), and I had a bad cable back then, but never made the connection (geddit?) between the problem and the cable...
My theory is that when the phone is running on bad power supply/not getting enough power, it sets a flag in the registry, which throws that error.
Also, bizarrely I just found that if you have internet sharing turned on then it won't let you connect.
Any of above mentioned did not work for me. I had many different error messages (included the 0x80070103)
What did is this:
Go to https://dev.windowsphone.com, uregister your phone.
Launch registration tool ("C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v8.0\Tools\Phone Registration\PhoneReg.exe")
Unregister in tool from 2) too (if it is showing still as
registered).
Now disconnect phone and connect it again
Register phone in tool from 2)
