Love-native-android - Development

Post by Moe » Sun Mar 18, 2012 11:20 pm

Hi,
let's start a new thread with development updates (for those who do not read the git log - I would not if I were not one of the maintainers :awesome: ). Please put any discussion into a different thread but do not hesitate to ask about unclear posts . And sorry for double, triple etc. posts, but I think a "new post" symbol is nicer to read than looking for "last edited" within posts.
So let's start:
fixed this annoying mutex error; added missing texture parameters for framebuffers
fixed a memory leak
Can somebody please verify that start up problems at the first start are solved (back and start a (new) game crashes always, no need to report, I am working on this point)?

I downloaded the latest source from the github just now, built it, and it crashes every time I start up a .love file, even the first time. Not just böack screen, entire app dies.

Do you happen to have some logcat output available?

Yes, best thing would be a logcat output from console, the one from Eclipse does not always print the stack trace... (call "adb logcat" in a console)
I did some more testing: The deinit method does not work properly and this leads to all the crashes on the second start (object memories are already freed and so on). The first start (or if I kill love apps by ddms before) works always fine on a Tegra2 device on Android 3.2 and a OMAP 3410 device with Android 2.1.
Maybe it would also help to know hardware/software configuration of your device (processor or device name is fine + Android version).

I have a HTC Desire with Android 2.3 (CM7.1), processor is Snapdragon S1 (QSD8250).

I have no idea how to get logcat from my device.

Open a console and type:
Linux:

Code: Select all

cd [ANDROID_SDK_PATH]/platform-tools
./adb logcat
Windows:

Code: Select all

cd [ANDROID_SDK_PATH]/platform-tools
adb logcat
replace ANDROID_SDK_PATH by the path of your SDK installation.

But surely I must connect my phone to my computer somehow? USB? And what settings do I need on my phone?

The same settings as for deploying from Eclipse should be fine.

I have never done that. So far, what I've done is merely exporting apk files and sending them to my phone. I will try to get logcat running and see if it works.

Totally works. Here's my logcat

I have finally set up my devel image (lubuntu 12.04 in VirtualBox, so might be using newer versions of software) and succesfully compiled and tested the project.
Works for me both on emulator and on HTC Desire. I have orderer a HP TouchPad tablet (yes, the only reason being love-native-android), will install Android 4 on it, so there will be another device to test.

My issues so far:
- I have to click twice to execute a *.love file from SD card (but I understand it is a known issue)
- the fonts are unreadable - I get only white blocks
- the volume button does not work - in iyfct.love I could not lower the music volume - had to exit the application (the music was still playing!), then the volume botton worked. However, to stop the music, I had to kill love
- in order to compile the project succesfully, I had to comment out 3 lines with @Override decorators in LoveRenderView.java (as advised by Eclipse)
My lovely code lives at GitHub: http://github.com/miko/Love2d-samples
