Hello, I would appreciate any assist with my problem:  
I’ve been struggling for several days compiling and building QGroundControll using QTCreator for Android.  
I’ve succeeded with building an APK package using Qt 5.15.2 Clang Multi-Abi, release mode, deploying and running it on Android Device and Emulators.

Problem: QGroundControll crashes on Android immediately after the App is opened.  
I’ve read in forums and operate accordingly and played with different versions of QTCreator, Android SDK API, Java and Gradle versions and even built a version with an empty main.cc  
Without solving the App Crashing problem.  
Thanks in advance for any assistance.

MY current Settings are (QGroundControll APK isn’t built using Gradle 2):  
Ubuntu 20.04  
QTCreator 4.13.3 Based on Qt 15.5.2 (GCC 5.3.1 20160406, 64 bit)  
Java: /usr/lib/jvm/java-15-oracle (I’ve also tried 8, 1.8, 1.11)  
SDK Version: 3.0, NDK Version: 21.1.6352462  
QT creator “Devices” is configured to run on Android.  
Used Kit: Clone of Android  
Qt 5.15.2 Clang Multi-Abi, Compiler and Debugger Android Clang (C, C++ arm, NDK)  
Gradle:  
Gradle-wrapper.properties - file: distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all.zip  
build.gradle - file:  
classpath ‘com.android.tools.build:gradle:4.1.0+’  
Video Streaming is disabled:  
GStream isn’t compiled when adding gstreamer-1.0-android-universal-1.14.4 and without it, it isn’t recognized even so it is installed.

You are not following the exact instructions as described here: [https://dev.qgroundcontrol.com/master/en/getting\_started/index.html](https://dev.qgroundcontrol.com/master/en/getting_started/index.html). Without that who knows what could be going wrong.

I’m by far after that,  
I did exactly as instructed, and Package wasn’t even built.  
My current settings are after a deep reading in forums and that is the only way I could compile and build the apk package. ☹

Whatever you are reading in forums is wrong. If you wan’t to know exactly how QGC builds android in CI looking at Travis.yml. It will show details on exact QGC, gstreamer and android SDK usage. That obviously works fine. If you replicate that setup it should work. Getting Qt+Android set up correctly is not super easy.

Hi,  
from what I see (correct me if i’m wrong) the dev guide [Getting Started · QGroundControl Developer Guide](https://dev.qgroundcontrol.com/master/en/getting_started/index.html) can not be followed as the mentioned qt version is not selectable.

i would appreciate hints how a correct / not wrong qgc android app dev setup and dev process should look like.  
the dev guide could be updated accordingly.

best regards  
rchrd  
. . . …  
p.s.  
dev guide says:  
“Download and run the [Qt Online Installer](http://www.qt.io/download-open-source)”  
anyway the installer doesn’t offer the version 5.12.6.

but 5.12.6. seems to be avaliable at [Index of /archive/qt/5.12/5.12.6](https://download.qt.io/archive/qt/5.12/5.12.6/) separately

dev guide mentions msvs 2017.  
[Supported Platforms | Qt 5.15](https://doc.qt.io/qt-5/supported-platforms.html) currently also mentions **MSVC 2019** below “The following platforms are supported in Qt 5.15.”

Hello, I have met the same problem that you described above.I’ve succeeded with building an APK package using Qt 5.15.2 Clang Multi-Abi, release mode.But it crashes on Android immediately after the App is opened.

SDK Version: 5.0, NDK Version: 21.3.6528147,jdk Version:1.8.0\_291  
android:versionName:3.0.0-243-gd759437  
versionCode=“300243”

I’ve been struggling for weeks to solve this problem.Have you solved this problem yet？Looking forward to your reply.Thank you.
