I uploaded a Flutter app to Google Play Console for some external testers to try.
In the Google Play Console there's a section Pre-Launch Report. In this section's "Overview" there's a subsection called "Performance", in here there are two items:
Cold start time
Your app took 6,982ms to launch for the first time, after being installed on this device model
and
Cold start time
Your app took 8,250ms to launch for the first time, after being installed on this device model
It has an arrow next to both items implying you can find out what device model had these huge start up times.
However, all it does is take me to a list of models that didn't have issues. That's not very useful to anyone.
Is there a way to find out what models it has issues on?
Look closely and you will see the device:

I tried various way's compile and update the firmware on my CC2650 Sensortag, more or less failed that.
Now I want the original functionality back. So I went to where I installed BLE 2.02 (simplelink\ble_sdk_2_02_01_18\examples\hex) and fetched the cc2650stk_sensortag_rel.hex. Programmed that with SmartRF. Now the Sensor tag is back in "near" normal operation. If I detach the programmer, remove the battery, then attach battery. The Simplelink on my Iphone can see a Sensortag 2.0. It notice when I push the buttons, but I can't see anything when using/pushing Sensor view or service explore. What can I do to get it back in it's original working state?
I don't know if I somewhat bricked the device trying to go over to Zigbee OTA and then trying to build/debug the IT resource explorer CC26xx Bluetooth Smart.
This is embarrassing. The SensorTag was working all along, a very important step was missed. Since I already tried uninstall/install the iPhone app I didn't think of switching off/on my bluetooth. The last step fixed the issue. Somehow settings where cashed there.
I need to demo my app to my supervisor. At the minute I have set all the testing up so that it works with the highway drive in cali. When I demo it I will be in an office (stationary) so the real location data for the phone wont show the demo results at all.
Is there anyway to make the iphone do the city drive? - When its running natively i.e. not connected to the machine.
There are various CLLocationManager simulators on github that you could include in your demo build, such as the CLLocationManager_simulator here.
Alternately you can set up your apps to record location data to a file and then create a CLLocationManager simulator that plays back the file. With that testers can record test drives and then devs can play them back in the office to debug or examine what happened or retest with new builds.
If you don't mind using the Simulator to demo it, there's simulated location available. Look in the Simulator menu under Debug -> Location.
I'm trying to figure out a way to mirror an iPad screen to other iPads. This doesn't seem to be supported on the platform though.
Basically, a teacher would have an iPad, then the students would have iPads and see everything that is happening on the teachers screen, but on their screens.
Thoughts?
I have been attempting to find a solution to this problem myself. I have not found any apps that can mirror exactly what is happening on another IPAD, but some come close.
RabbleBrowser and Ideaflight both had potential. Ideaflight appears to be more for business. RabbleBrowser appears to allow the mirroring, except it only works as a browser and a file/picture mirroring.
Both iPads are linked to the same wifi and when you join a session, they will mirror the iPad that started session. Also allows chat (controlled by session starter).
It does NOT continue to mirror if you move out of browser and into another app however. I had dreams of leading a class through a a lesson on google earth, but no go .:(
Another option is attaching a laptop to a projector. Then you download Airserver on the laptop. Go to the menu bar at bottom of iPad and turn on AirPlay. The laptop will mirror the iPad perfectly and project it! It's wireless and works well. I tried the HDMI connector to laptop but it gives a poor quality, shaky image.
Hope they allow mirroring in future updates. The capability is there, don't know why they don't! Guess trying to sell more appletv!
A similar question was asked on the Apple forum (https://discussions.apple.com/thread/3118281?start=0&tstart=0), and the following app seemed to help them or answer their question.
Have a look at Replicate Pro on the app store:
http://itunes.apple.com/us/app/replicate-pro-for-ipad/id363286515?mt=8
One feature listed in the notes:
Share files between two iPads/iPhones that are running this app. (Pro
version only)
I'm not sure if this will cover multiple devices or simply between two, but it may be worth a look. Sadly, the only way to try would be to spend $5.99.
You'll need to create an application for the student iPad that emulates the screen of the teachers iPad. I would suggest that, although i dont know if its possible, the teacher somehow starts up and app that emulates their entire iPad. Meaning, from within the app named "teacher share" (or whatever it is), they can access the music, settings, notes and other apps found on their ipad. Then that information could be sent over a network to the students.
Nearpod is an app that will allow you to mirror a presentation on several iPads. I have had up to 9 at one time. Through the Nearpod program you can make a presentation similar to PowerPoint, and also incorporate interactive questions, which can be multiple choice, short answer, and even drawings. The only drawback is the full version costs $10/month. The free version is still good, you are just limited on the size of the presentation.
After doing lots of research, I found one app which shares iPhone device into another iPhone device. Really great logic they have applied for screen mirroring.
No idea about detailed how they have implemented but after installing and checking the app I came to know that I think they have used iPhone Screen Recording and broadcasting it on to their server and then on another device they are syncing from the same URL.

I have an app that I added a lot of animation to. The app also used "iPhone sleep preventer" to play silent audio. Since then, I noticed that the battery consumption increased by up to 4 times! I'd like to find a method to profile the power consumption (I think I saw an option in Instruments) to find and eliminate the offending method(s).
Where would I start looking for information like this? Currently I have the phone left on the desk for ~3 hours to record power drain over time. Is there a better method to predict when the app will run out of power if running my app continuously?
An extra side question: are the % of battery left displayed in the status bar linear or is there some non-linearity towards the end of the battery life?
Edit: I found a "power" preset in xcode>product>profile>CPU>Energy diagnostics. It doesn't seem to work perfectly, as the power consumption level is always 0/20. But it does tell me how much of the CPU time is spent on app foreground, graphics and music!
Now I dont know how the CPU power is managed, is running the CPU at 75% more power consuming than lets say 30%? Intuitively it feels like it should...
Thank you!
I'm no expert. Im fact I am only starting to power profile a iphone today, and looked upon your question here in hope off learning.
So I will share with what I've found in meanwhile.
On IOS Developer Library I have found the following:
Connect the device to your development system.
Launch Xcode or Instruments.
On the device, choose Settings > Developer and turn on power logging.
Disconnect the device and perform the desired tests.
Reconnect the device.
In Instruments, open the Energy Diagnostics template.
Choose File > Import Energy Diagnostics from Device.
And you have a report of Cpu and energy during the time of the log.
You can find this steps and many more info on this section of the IOS Dev. lib.
I am still a bit fresh on this matter, so if you find anything that you think is meaningful please post that info here.
Edit: The apple dev lib suffered some changes. Updated link
I've got an app I'm building using Appcelerator Titanium that will be a combination alarm clock/url fetcher. The part I'm having problem with is that I need to be able to set a time for the app to go fetch the url and then perform actions as necessary (in this case alert the user if data that should be entered in a time system has been entered). I also want it to do this every day (or every week day) at the prescribed time, and I want it to not have to be 'launched' every time. I'd rather it come up and run as a service, or at least run as a service when sent to the background. I'm most focused on the iPhone, but I've got a few Android users that would like it as well.
Is it even possible to have an Appcelerator app hooked into the system like that? If so, are there any tutorials or examples? I can't even find an alarm clock example, which scares me a bit.
I think that localNotifications should work for you.
there is a sample in the bg.js file included in the kitchenSink.
It is also helpful to know that all of the keys/properties available to you are documented here in the source code.
This guy has a nice alarm module written for android.
