White/Blank screen on Android Simulator

tonyhhkx

Dear All,

if i run the test HelloWorld application with QT Creator on Android Simulator the system shows a white blank screen.
How is possible to fix this?

I'm using a Mac.

@tonyhhkx
is that the whole output?

If so you need to post your logcat pls. But clear it before you start the app to keep it at small as possible.

adb logcat -c
>>> START YOUR APP AND LET IT CRASH
adb logcat -d > logcat.txt
>>> POST CONTENTS OF logcat.txt HERE

really thanks for the info. Iìm sorry but is my first time with QT. COuld you please explain in which console can i put the lines?

raven-worx

@tonyhhkx
in your system's console. adb comes with the android sdk.

in your system's console. adb comes with the android sdk.

please note that i using QT Creator and lunch automatically the Android Emulator without use Android Studio:

alt text

@tonyhhkx

Please note also that if takes the .APK debug file and installs on my Android Device, seems work fine, but not exactly.
If i switch to home and then switches to application , the application crashed!
Could be a problem linked to this post?

This is a simple application

as i said, adb is part of the Android SDK. Call it directly from there.

sorry but this is my first experience i i don't understand how do this call. Which terminal i need to open? How can i open?

@tonyhhkx
simply with your system's shell.

/path-to-android-sdk/platform-tools/adb.exe ...

@tonyhhkx said in White/Blank screen on Android Simulator:

W/libtestEmulator.so( 3301): (null):0 ((null)): QOpenGLShader::compile(Vertex): ERROR: Valid GLSL but not GLSL ES
W/libtestEmulator.so( 3301): (null):0 ((null)): *** Problematic Vertex shader source code ***

these are the lines i would be suspicious about.

Seems this is only a Emulator related issue.

@raven-worx

so is not possible to fix? Is very strange.

I tried to tun the emulator beforw with hte following command lines but nothing change:

emulator -avd Galaxy_Nexus_API_22 -gpu host
emulator -avd Galaxy_Nexus_API_22 -gpu on
emulator -avd Galaxy_Nexus_API_22 -gpu off
