Can't debug android application - Connecting to remote server failed

lqsa · 7 Jul 2017, 05:57

When I try to debug an Android app with a mobile with Android 7, appears this message:

Connecting to remote server failed:
Remote communication error. Target disconnected.: No error.

The same app with two diferent phones with Android 4 debug without problem.

Any ideas?

Are you trying to connect with USB on windows?

There is a note for windows

Otherwise you need to state your OS and version of Qt.

Yes, from Windows. I've already installed the USB driver, like says on the note, and already debugging on another Android devices.

I'm debugging on a Samsung S4 mini (Android 4) and Energy Colors (Android 4). The problem is with a Motorola G4 Plus (Android 7).

My OS is Windows 10 Pro (with the latests updates) and Qt 5.9.1. The same problem with Qt 5.7. Other versions of Qt hasn't tested.

It's very strange. I've tested two samples, places and contactlist, and can debug it. I suppose that is something on my project.

@lqsa

Did you compile it already as application for windows?
That may help, but you cannot test any specific Android stuff.

Good luck for solving your issues.

I found it. The problem was that I'm using a tools greater than 25.2.5 and QT doesn't detect the SDK (see [https://bugreports.qt.io/browse/QTBUG-61705](link url)). After install and use it, it debugs.
