[tool] LoveToAndroid - .love to .apk without thinking

[rayaman]

Wow this is amazing! Thanks so much no more head banging for me

[laperen]

anyone have more detailed instructions on how to change the game name and id? I was editing the make-apk.bat. I was only able to change the apk name. changing anything else "that starts with sed" either made the apk assume there was no game, showing the super-toast screen, or outright refuse to run.

laperen: sure, I wrote some more details in the description of the android video on YouTube but let me make a more thorough explanation here.

It seems that if you install two apps with the same name, this can cause installation to fail on some systems unless you uninstall the previous version. I'm guessing it's a safety feature.

For this reason, for speedy development, I made the game name change constantly based on date/time.

I added a keyword to the manifest.xml (the file that defines things like name or orientation of the game), which is then replaced using the command line tool sed.

To change the name in the current version of make-apk.bat, as seen below:

Code: Select all

@echo off
rem get date and hope no participants compile at the same second
set hour=%time:~0,2%
if "%hour:~0,1%" == " " set hour=0%hour:~1,1%
rem echo hour=%hour%
set min=%time:~3,2%
if "%min:~0,1%" == " " set min=0%min:~1,1%
rem echo min=%min%
set secs=%time:~6,2%
if "%secs:~0,1%" == " " set secs=0%secs:~1,1%
rem echo secs=%secs%
rem set year=%date:~-2,2%
rem echo year=%year%
set month=%date:~3,2%
if "%month:~0,1%" == " " set month=0%month:~1,1%
rem echo month=%month%
set day=%date:~0,2%
if "%day:~0,1%" == " " set day=0%day:~1,1%
rem echo day=%day%
set datevar=%month%%day%%hour%%min%%secs%

The important line for you is:

Code: Select all

tools\sed-win\bin\sed -i "s/loveToAndroid Game/Game %datevar%/g" tools\love-android-sdl2\AndroidManifest.xml

If you game is called "Blueberry Escape", change it to:

Code: Select all

tools\sed-win\bin\sed -i "s/loveToAndroid Game/Blueberry Escape/g" tools\love-android-sdl2\AndroidManifest.xml

Alternatively, you can go to StartGamedev-160804-win/tools/love-android-sdl2/original/ and edit the AndroidManifest.xml file there, find the two lines that contain the following:

Code: Select all

      android:label="loveToAndroid Game"

And replace "loveToAndroid Game" with your game name (be careful not to remove anything else, one " less and the file is broken

PS: as for the ID, this is a bit more tricky. You will have to replace every instance of love\.to\.android%datevar% in the script (use ctrl+f in notepad++ or another editor that is not notepad which is too basic to allow keeping track of ugly files) and make sure the right folders exist in StartGamedev-160804-win/tools/love-android-sdl2/src.

Your issue might be the result of other android dev activity. Try temporarily renaming or removing your ~/.android/ directory (solution from http://stackoverflow.com/questions/1115 ... pplication ):

Code: Select all

mv ~/.android/ ~/.android-bak/

Another idea: Try uninstalling (or temporarily renaming) your locally installed Android SDK.

Are you on 32 or 64 bit Linux?

Thank you for the response. I think as far as my small project is concerned changing the game name will suffice. I will follow up on changing the ID in future. thanks again.

Thanks @qubodup for your reply. I'm on Linux 32 bit. A long time ago, before even knowing löve, I unsuccessfully tried to learn Java programming for Android. By that time I could find the SDK for Linux 32 bit, and the files stayed. Right now I can't install SDK for Linux 32 again, but I thought that it was included in your package. I followed your suggestions of deleting old files and renaming folders, but I still can't do anything... the same error you pointed out appears.

[qubodup]

I followed your suggestions of deleting old files and renaming folders, but I still can't do anything... the same error you pointed out appears.

Try:

Code: Select all

sudo chmod -R 777 ~/.android

(from http://stackoverflow.com/a/8783686/188159 )

Or:

Code: Select all

cd ~/.android
keytool -keygen -v -keystore debug.keystore -alias androiddebugkey -storepass android

(from http://stackoverflow.com/a/14078157/188159 )

Or add

Code: Select all

export ANDROID_SDK_HOME="$PWD/tools/android-linux"

under line 16 in make-apk.sh
(from http://stackoverflow.com/a/12362172/188159 )

Another thing to try: move or copy the startgamedev folder to your home or Desktop to shorten the path and try again (seems more of a possible DOS problem though )

PS: yes, you don't have to install Android SDK for StartGameDev. Reading your post, I thought that you did install it just fro StartGameDev though. But when all the ANDROID_... variables are set, the other installation (if there is one) shouldn't be in the way.

[scissors61]

Sadly, no results. Couldn't do your second suggestion, it says something like keygen is not an allowed option. Something that I notice is that start-game.sh doesn't start the game. Only a black screen appears.

[qubodup]

Something that I notice is that start-game.sh doesn't start the game. Only a black screen appears.

No problem, that's for the tutorial in which you write a game inside Game/.

Sadly, no results. Couldn't do your second suggestion, it says something like keygen is not an allowed option.

Ok, looks like that might have been a command for an older Java.

I learned a lot today. The package requires JDK and JRE 8 (1.8) when used on Linux unfortunately. But it would have been too nice if Linux portability would have been possible easily.

If you run java -version, you will probably see 1.7.

What I had to do to make this work on a 64bit Ubuntu 4.2.0-16-generic virtual machine:

Code: Select all

sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install openjdk-8-jre-headless
sudo apt-get install openjdk-8-jdk

and then make-apk.sh works.

It might be possible to download JDK from sun's website of the version you have, and replace the folders in tools/. No guarantees.

[scissors61]

It worked! I installed first JDK 8 on my system, and no luck. Then I did what you told me about downloading JDK from sun's website and replace the files in tools, and that did the trick! Thanks for your assistance and for this great tool.
