[Solved]Official Qt 5.1 android application deploy error on device ..

p3c0 · wrote on 7 Jul 2013, 11:11

hi all,

I downloaded the latest official Qt-5.1 for android using the offline installer Qt 5.1.0 for Android (Linux 32-bit, 463 MB) , latest ndk (android-ndk-r8e-linux-x86.tar.bz2) sdk(adt-bundle-linux-x86-20130522.zip),Ant tool v1.9 and Java jdk 6. I did the necessary configurations in QtCreator's(Setting ndk,sdk, ant and jdk) Projects > Android.

I'm using GCC 4.4.3 for compiling with arch armv7-a. I have set Android Target Sdk to Android-10
The code compiiles fine and apk is also created but i get error "Your application encountered fatal error and cannot continue".
My target device is android tablet. Following are details

Android 4.0.3
getprop ro.product.cpu.abi = armeabi-v7a

Following is the more detailed log from logcat from device:

"Logcat Error logs on device":http://pastebin.com/43Je5Wxr

So am i using the correct NDK, SDK's for development ? or is there any other configurations to be done ?

Ye, the ndk and sdk are fine.
Do you use openjdk 6?
Ive been using ant 1.8.2 so far and its good, but I dont think 1.9 would cause this.

What are your deploy configurations?
Maybe share the source code? It looks like some simple example

Thanks for reply Moster,

Yes i'm using openjdk 6.
I have kept "Use Qt libraries from devices" and checked "Use Local Qt libraries"

Yes its a simple Test code with QMainwindow nothing else written in code.

The following is first compile output:

P.s: ignore the strikeouts

You can use code tags to avoid strikeouts

I have introduced the code tags for you.

Ive googled your issue: cannot locate '__aeabi_ldiv0'...
Not really satisfying: https://github.com/paddybyers/anode/issues/12
You dont have another device to test it?

p3c0 · wrote on 7 Jul 2013, 12:52

hmm. I also tested it on my HTC Desire V android version 4.0.3. The same problem occurs.
Moster, are you using the latest officially release Qt 5.1 for Android ?
Because i have been using Necessitas which uses qt4.x previously and the Apk built used get deployed with no issues on both devices.
Can you upload a sample .apk built using your toolchain ?

Moster · wrote on 7 Jul 2013, 12:59

I can of course do that, but the problem seems to be ICS (api level 15), since the same error occurs on the emulator. It does not happen with other api levels.

here is some test apk https://mega.co.nz/#!pp8EQCiI!TgGvuE7BL4LaLar9jkwYaivEP04FKO6lrtUS6t6s3d4

It has some buttons on it

p3c0 · wrote on 7 Jul 2013, 13:18

Ok. I have even downloaded the API level 10 which is for ICS 4.0.3 and also compiled against it.

Moster · wrote on 7 Jul 2013, 13:22

I mean, its android 4.0.3 itself (api 15) that causes this error. Api 10 is android 2.3.3 (gingerbread). There seems to be some library or whatever on 4.0.3 that fails while loading the qt5 libs

p3c0 · wrote on 7 Jul 2013, 13:31

Moster, Your Apk worked on my device. 3 Buttons and 2 radiobuttons.
Well now can you just post exact details related to Qt.

Qt version
Android NDK version (Possibly provide exact download link)
Android SDK version (Possibly provide exact download link)
Open JDK version
Ant tool version
Package Configuration > Android Target SDK
Deploy Configuration
Android Kits as seen in "Build & run" > Kits
Qt Versions as seen in "Build & run" > Qt Versions

It would be very very helpful.
Thanks in advance.

Thanks,
The changes that are on my side is that i'm using 32 bit ubuntu 12.10 and Ant 1.9 . I don't know whether it is causing the problem. Also i tried with Open JDK 7 but no success.

I can only test it on the android emulator with ICS(4.0.3).
But it seems to be GCC 4.4.3, with 4.6 and 4.7 it works

p3c0 · wrote on 7 Jul 2013, 14:45

Well thanks for all your support, ill now try with 64 bit ubuntu.

tgriffith · wrote on 17 Jul 2013, 19:34

I was getting the same error as you, and I was using the same Qt details to compile with.

I am no longer getting this error after switching from 4.4.3 to 4.7.

That's what I also said in my latest post. I guess he didnt try it.
