Delphi 10.3 and the NOX emulator running Android 7

[Yaron 53]

It seems that Delphi 10.3 generated APKs are not compatible with the NOX emulator running Android 7.

 

The moment I try running the APK, I get a message that the application closed.

 

This happens with every APK I generate (e.g. https://github.com/bLightZP/ElegantCalculator).

Trying to debug the issue, it seems that my first line of code is not even executed before the app closes.

 

Any ideas?

Is this emulator also emulating ARM code to x86?

[Yaron 53]

I believe it does, other apps and games work fine, my own apps used to work fine on v10.2 ...

[Cristian Peța 103]

Time to look in the log.

[Yaron 53]

Which log are you referring to?  The app closes before it reaches my first line of code?

[Cristian Peța 103]

I used "Andoid Device Monitor" from SDK that installed with Delphi (starting  \sdk\tools\monitor.bat) but it doesn't start with Rio installed SDK. At least for me.

You either install Android Studio and use Logcat: https://developer.android.com/studio/debug/am-logcat

Or other solutions: https://android.stackexchange.com/questions/14430/how-can-i-view-and-examine-the-android-log

How did you manage to make Delphi recognise the emulator? I've got a similar situation and cant make it see the emulator. 

 

And something else? Do you use any virtual machines or directly on the main PC?

I am not trying to use NOX as the debugger, I'm trying to get it to run my compiled APKs simply by dragging the APK onto the NOX window which installs just fine.

But as soon as I try to run any Delphi 10.3 app on NOX, it instantly closes with an error message that the app has closed.

 

And I use it on my main PC, no virtual machines (other than NOX of course)

If adb connection is not working then installing a Log visualizer from the market is the easiest solution to see the log.

Have you tried a simple project that does nothing?

Can you post a link to one, I tried a search on the google play store and it only came back with text viewers.

Yes, created a new multi-platform project, compiled & deployed it without any changes, installed the APK on Nox and it crashes with "Project1 keeps stopping" instantly when executed.

[Cristian Peța 103]

Search for Logcat.

But looks like starting from Android 4.1 reading logcat is no longer working without root access.

I have recently (last couple of days) been (re)-introduced to the wonderful world of (trying to) get set up with an emulator to do Android development with Delphi.   🙂😞😫

 

(Had lots of fun and games trying to make the default Android SDK emulators work  ... eventually started looking into alternatives including Nox... hence my response to this post)

 

Suffice it to say that:

• I can successfully run .apk's produced with my newly recently installed 10.3.1 Rio installation by dragging and dropping the .apk onto Nox version 6.2.7.1. 
• I've also managed to make nox show up in Rad studio and deploy directly to nox, with some fiddling with adb:
  • In short, after running Nox and following the instructions here: https://www.bignox.com/blog/how-to-connect-android-studio-with-nox-app-player-for-android-development-and-debug/
  • ... and then also using the adb.exe shipped with RAD Studio, e.g. the one in C:\Users\Public\Documents\Embarcadero\Studio\20.0\PlatformSDKs\android-sdk-windows\platform-tools  to run:
    • adb connect 127.0.0.1:62001
    • system responds: connected to 127.0.0.1:62001
  • ... refreshing the "Target" node then displayed the Nox emulator as a valid android target:
    
• I have however not managed to debug directly on Nox, this fails every time with the app stuck on the firemonkey icon and the Delphi debugger terminating immediately upon startup.  Not sure what's going wrong or how to debug this yet.
• As a digression, I've also found (irritatingly) that out of the 2 phones I have available, debugging also doesn't work on the newer one (Note 8 ) because of "reasons" (something Google changed supposedly and Emba therefore says they won't fix), while it does work on the older phone (note 4). Meanwhile the test app I've tried while starting on both behaves rather inconsistently in regards of camera feature control (flipping between front and back cameras works on one, doesn't on the other, and setting the auto-focus mode doesn't seem to work the same between the phones either.)  Perhaps these are all teething issues and possible to be worked around... 

Hope that helps.

If your Note 8 has Oreo 8.0 OS then debugging does not work because Google screwed up on OS level. You need to update OS to 8.1 that fixes the issue. It was not something EMBT could fix.

Thanks, Correct yes.  That's what I read/was referring to.  And my apologies, I shouldn't have used "won't" in my post, should've been "can't". 

 

As it happens I see I've been prompted with an OS update/upgrade notice last night on said phone (which will upgrade to Android Pie) so hopefully the problem will be gone later today! 🙂

I managed to get a logcat of my app not loading in Nox (this also happens with a blank app):

I'm not proficient enough to understand the debug out, can anyone shed any light?

Are you running Nox with the Android 7 image?  By default Nox will run with older versions of Android.

I am looking for this solution too.
