Android Question [SOLVED] [B4A] installing time very large

[sirjo66]

Hi folks,
I downloaded "Camera2" Erel example from https://www.b4x.com/android/forum/threads/camera2-still-images-and-videos.83920/
Then I connected a smartphone to PC (via USB cable) and press F5.
In attachment the screenshot.
I don't like 68 seconds for to install in my smartphone (the APK file is 4.7 MB, very small)
I tried "clean project", I tried disconnect, reconnect, delete adbkey and adbkey.pub files for to ask again RSA key, but no solution.
So, I tried to use and old smartphone with Android 8 and 16 GB (very slow smartphone) and the time was 35 seconds (very well for an old phone)
I think that the problem is the smartphone, but what can I do ?
My main smartphone has 128 GB (83 GB free), Android 12, and I use an app for "to clean" the smartphone every day (app by samsung).
Any idea about it ??
Many thanks
Sergio

Hiya,
I downloaded the Camera2 and ran it.

First run times

Second run times

Absolutely no timing issues here using B4A-Bridge.

Assembled on an Asus duel screen i7, 16GB, M.2 laptop.


Enjoy...

I tried with B4A-Bridge.
For IDE to phone very very fast (about your screenshot), but then on phone time for to install: 51 seconds.
(and I need to click three times on phone, and I don't like so much.)
Why with the USB cable is so slow ??

Hiya,

Why with the USB cable is so slow ??

Try another USB cable. I already know that the cable is faster than the WiFi, it always is in my case.

Note that the installation step, without B4A-Bridge, is 100% managed by Android SDK - with the ADB tool.

And you should use latest version of B4A.

I tried to update B4A, SDK, changed USB cable and used another PC
No change

Edit: I updated also "Samsung USB driver mobile", no change

SOLVED !!!!!!
In the DEBUG settings of the Samsung smartphone, you need to uncheck "Check applications with USB"
See attachment: before was 60 sec, now 1.77 sec

I have never come across that setting before. It does indeed make installation a lot faster! Well spotted.

"Check applications with USB"

I didn't find such a setting in Samsung Galaxy S23. What is the exact name when using the English layout of the device?

Just connect directly over the network using adb. Your device will be seen by B4A like directly connected to the PC and is a lot much faster than connecting over USB.

Just connect directly over the network using adb. Your device will be seen by B4A like directly connected to the PC and is a lot much faster than connecting over USB, especially with big applications.

This is a screenshot from my S23. The actual wording on my phone is "Verify apps over USB". It's about 6 settings down after the "Wireless debugging" setting.

This is a screenshot from my S23.

Thanks, found it!
But on the emulator this option is inactive.
