Guide to build the project and generate APK

[floviolleau]

Hi,

I would like to compile the project and generate the final APK but I don't see any documentation.

Can you please write basic steps?
I'm familiar with compilation and linux tools but not so much with Qt and Android.

What I did:

1. I'm under ubuntu x64 on a Latitude E7240
2. I already downloaded:

• Qt for Android 5.1.1 x64 (not able to find a 5.2 on their website and I saw in the code: private static final int QT_VERSION = 0x050100; // This app requires at least Qt version 5.1.0)
• NDK r10e,
• Android SDK,
• Android Studio

3. I cloned the official repository of OpenCPN (without doing anything // didn't compiled it)
4. I cloned your repository
5. Changed in the file OpenCPN-Android/app/build.gradle paths:

• Qt_Base => to the place where I extracted Android Qt when running qt-linux-opensource-5.1.1-x86_64-offline.run
• OCPN_Base => to the place where I cloned OpenCPN

And it is complaining in any places where there is an import to Qt:

error: cannot find symbol
import org.qtproject.qt5.android.QtNative

I don't know how to put all pieces together. I'm missing to plug Qt to Android Studio

Can you please help me?

Thanks

I'm having the same issue as floviolleau. Not sure where the QT plugin is originating from. I'm using a fresh installation. Is this a gradle sync issue? I changed everything to use SDK 29.I tried forcing the Qt files in but that just pushed new issues into the mix.

@hellooutthere2 ...
The build process for OCPN Android is under large revision now, pending the upcoming release of wxWidgets 3.2. Suffice to say that the current available instructions are overly complex, and just plain wrong for modern OCPN builds.
Please stand by for a bit as we stabilize the build instructions.
Thanks

Any updates on this. I am trying to compile it now, but are getting all sorts of errors.

The file 'org.opencpn.OCPNChartInstallActivity' is not in the project. Can you share it?

@bdbcat
Is this project complete at present, and can it be run on AS by downloading the source code directly?
I don't see any document.
Can you please help me?
Thanks

No implementation found for int org.opencpn.OCPNNativeLib.onStart()
I got this error, and I don't find 'build_android_64_cci_22b' library in OpenCPN project.
