Announcement for Qt developers targeting Android 6.0

LucasDanzinger

Starting with Android 6 (marshmallow), Google has moved away from OpenSSL to their own SSL implementation called BoringSSL. This affects all Qt developers targeting Android 6 and later, as libssl.so and libcrypto.so are no longer available from Android, causing https requests to fail in Qt applications. The solution suggested at this time by The Qt Company is to compile these libraries and package them in the APK with the ANDROID_EXTRA_LIBS qmake variable. For example, you could build the two libraries from OpenSSL, copy them into your Android kit’s lib folder, and then add the following line to your project's *.pro file:

android <SPAN class="punctuation token">{</SPAN>
&nbsp;&nbsp;&nbsp; ANDROID_LIBS <SPAN class="operator token">=</SPAN> <SPAN class="token function">$$dirname</SPAN><SPAN class="punctuation token">(</SPAN>QMAKE_QMAKE<SPAN class="punctuation token">)</SPAN><SPAN class="operator token">/</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="operator token">/</SPAN>lib
&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; ANDROID_EXTRA_LIBS <SPAN class="operator token">+</SPAN><SPAN class="operator token">=</SPAN> \
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $$ANDROID_LIBS<SPAN class="operator token">/</SPAN>libssl<SPAN class="punctuation token">.</SPAN>so \
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $$ANDROID_LIBS<SPAN class="operator token">/</SPAN>libcrypto<SPAN class="punctuation token">.</SPAN>so
<SPAN class="punctuation token">}</SPAN> 
<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

This suggestion is applicable to any Qt developer targeting Android 6, whether using ArcGIS Runtime for Qt or not. Therefore, if you are using ArcGIS Runtime SDK for Qt, this suggestion is applicable whether you are using 10.2.5, 10.2.6, or Quartz (which is currently in beta). See the Qt documentation for further details on how to build OpenSSL and integrate the binaries into your project. In addition, licensing requirements for OpenSSL can be reviewed at https://www.openssl.org/docs/faq.html#LEGAL1  and https://www.openssl.org/source/license.html.

Hi Lucas ,

We are using Windows development environment and Arcgis Runtime SDK for Qt 10.2.6 and Qt 5.4.2 (MSVC 2013, 32 bit) Qt Creator QT\QML side. And we are develop and deploy Adroid app with Android Armeobi-v7a (GCC4.9 , QT 5.4.2) kid.

We have Galaxy Tab 2 and our application is correct working (wcf login services wich use "https requests") in Android Operating System 5.0.2 Version but when I update My Android OS to 6.0.1 and then when I tried to use wcf (login) services gives exception .

 Can I sent our sample App example to you for fix this settings in our sample application ? Because I have not been able o do this hard work.I did not fully understand solution because we are using Windows development environment .Can you help me ?

We are using below code (in Main) for passing certificate:

QSslConfiguration config = QSslConfiguration::defaultConfiguration();
config.setPeerVerifyMode(QSslSocket::VerifyNone);
QSslConfiguration::setDefaultConfiguration(config);

Here is also our exception console output below;

D MenuDenemeNumarataj: (null):0 ((null)): int main(int, char**) ApplicationWindow_QMLTYPE_165_QML_191(0x9bbe2460)
D mali_winsys: new_window_surface returns 0x3000, [1536x2000]-format:1
D libGLESv2: DTS_GLAPI : DTS is not allowed for Package : com.mycompany.myappname
D ViewRootImpl: ViewPostImeInputStage processPointer 0
D ViewRootImpl: ViewPostImeInputStage processPointer 1
F libc : Fatal signal 11 (SIGSEGV), code 1, fault addr 0x8 in tid 20871 (QtThread)

How Can I solve this problem ?

Best Regards
