LazSDL2 package for Android development

[Imants]

I have advanced my LazSDL2Design package little bit. Now I am trying to create easy android development inside Lazarus. My main goal is to developer press build button in Lazarus and he gets ".apk" file and do not manipulate any java code or any other android specifics file.

I have written about how I set up my cross compilation enviorment in Ubuntu 64 bit here: https://xp-dev.com/wiki/232197/Installing%20Lazarus%20multi-platform%20environment%20on%20Ubuntu%2064-bit

And I have written little bit about how to configure Lazarus for android development here: https://xp-dev.com/wiki/232197/LazSDL2Design%20package%20configuration

And I have written how to start develop cross compiling Lazarus project using my LazSDL2Design package here: https://xp-dev.com/wiki/232197/LazSDL2Design%20package

Thank you for working on this. 

However, I tried to set-up a working environment and it seems I failed.  I couldn't compile the sdl_android example successfully.

There were no instructions about the binutils so as the compiler failed, unable to find them, I created symbolic links to the ones in the Android NDK (ar, as, ld) in /usr/bin.

The compile now fails at the link stage complaining that there is an invalid STRING in the link.res file which seems to be temporary since I can't open it (Lazarus can't find it).

On investigation, I'm concerned about a $Android(libraries) reference in the configuration.  I'm not sure what this would or should resolve to or how it is configured.  I am uncertain what the error is caused by though.

Further help would be very much appreciated.

Thanks again.

[Imants]

Thanks for trying to use my project I am in very dire need in additional testing

I created symbolic links in $HOME/bin for

arm-linux-androideabi-as -> /<path>/android-ndk-linux_11/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-as
arm-linux-androideabi-ld -> /<path>/android-ndk-linux_11/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ld
arm-linux-androideabi-ld.bfd -> /<path>/android-ndk-linux_11/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ld.bfd
arm-linux-androideabi-ld.gold -> /<path>/android-ndk-linux_11/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ld.gold

I think /usr/bin will work too.

Have you set path to android SDK and NDK in Lazarus->Tools->Options...->SDL2->General ?

I could not set these paths automatically because fpc compiler used them internally and I for now do not know where to set them so that fpc see them

[mewpokemon]

Whoops..  Sorry, I made the links in /usr/local/bin.  I had set the paths in Tools|Options.

Adding the links for *ld.bfd and *ld.gold made the difference.  These weren't in the official instructions I was trying to adapt.  The project now compiles.  I get libexample.so in the dist/arm-android directory.

Would you be able to provide further assistance?  I'm very new to Android development, especially from the linux command-line.  I have really only used Delphi and Flash Builder for it.  How do I package the libs etc into an apk for installation?

Thanks for your help.

[Imants]

Yes I know that this is not in official documentation because I totally forgot about this before you reminded me . I will write it somewhere 

If you have set build mode Android in example project  (witch is default) and set "ant" path in SDL->General options Lazarus should generate ".apk" file automatically. Whole purpose of my package is to create ".apk" file without android knowledge . There was bug in my project that it would do nothing if ant is not specified and no error messages will be given

Now I am making so that you can automatically sign your ".apk" file too.

[skalogryz]

Whole purpose of my package is to create ".apk" file without android knowledge

What about other Android oriented packages, aren't they generating .apk files themselves?

[mewpokemon]

I configured ant to be /usr/bin/ant.  I think it was already installed but I made sure by installing the ant packages.

I don't think its working.  The last message in the output is about copying the libexample.so to libmain.so.  There is no build.xml if there is supposed to be, either.

Could I be doing something wrong?  Do I have the wrong ant?

[Imants]

No at that point ant should not be used.

I library coping was successful
You should get message "Copying resources"
If you do not get this message something went wrong with copiing .so files.
Can you post me Lazarus compiler message log content?

I do not know any android oriented package in lazarus there was some project where was predefined some android stuf but that is it. I am here more striving to get Delphi like experience where you press build in Lazarus and you get working "apk" file

[Imants]

This is how looks Lazarus message for successful compilation. Ant starts to work only at "Progress: Building android" step

It seems it stops just before "Copying resources" and should have output "Progress: Android Dir: ...".  I can't tell what might be wrong.

It was bug from my part a very noob like bug 
But thanks to you I found it

Here are quick fix for the shameful bug I hope you will give a try

I tried with the version set to android-19 and still no good. 

In the bulid.xml file on line 538 it says

Code: [Select]

minSdkVersionOut="project.minSdkVersion"
Should it say?

Code: [Select]

minSdkVersionOut="${project.minSdkVersion}"
I wonder because the other place it references that it uses that syntax.  I don't know anything about ant and build.xml though.

Almost there...

[Imants]

Go to Lazarus->Tools->Options..->SDL2->General and press Update SDK button.
Then Android SDK manager will pop up. Install Android 4.1.2 (API 16) -> SDK Platform package.

[mewpokemon]

Dang!  I thought I'd done that.  Doing so certainly fixes the .apk build problems.  Unfortunately, I'm having trouble with getting USB devices to work with the VM so adb can't see the tablet and the build process can't install the .apk.

I transferred the .apk file over to the host system (Windows...  *sigh*) and used adb to install it.  When I run it, a black screen appears for a brief moment and then the application "exits".

When I check the logs, I can see that SDL is initialising correctly and I'm getting the SDL_Android_Init() message but the SDL thread simply exits soon after and the activity ends.

Is the example application meant to do something other than this or is it just for debugging to show that an activity can be run?
