Virtual Machine + Lazarus + Android

[felipemdc]

I compressed with the standard Mac OS X zipper, so I am not using any unusual zipper. Probably those utilities have an old version of the zip library. In the case of peazip I vaguely remember the crc problem in the bug tracker if it uses paszlib.

Anyway, I could start the virtual-machine now. But when I start lazarus, I get immediately the error message "Compiler "usr/bin/fpc" does not support target arm-linux.

Ignore this error, it is false. I don't know why it says that, but it works despite that.

Ok, it is uploaded:

https://sourceforge.net/projects/p-tools/files/Lazarus_for_Android_VM_Image/snapshot_30_dez_2011/

Works beautifully.  Thanks much.  It works for me using Qemu/KVM on a headless "funtoo" server and connecting via VNC like this:

 (after extracting image and renaming it to remove spaces)

Code: [Select]

qemu-system-x86_64 \
  -name "Android_Devel_VM.hdd" \
  -drive file=./Android_Devel_VM.hdd \
  -net nic \
  -net user \
  -m 1024 \
  -usbdevice tablet \
  -enable-kvm \
  -vnc :1 \
  -vga vmware \
  -snapshot

(note the "-snapshot" param is for testing, it prevents permanent changes to the base image.)

How do you generate a release version of andriodlcltest/androidlcltest.apk?  Will the APK be smaller with no debug data?

Thanks,

Wayne Sherman

Works beautifully.  Qemu/KVM...

After some more testing in Qemu/KVM, I have seen a little instability, but it looks like it will work for the most part.  I discovered I couldn't run from the image and store changes to it directly so I created a branch/delta file using the image file as the base:

Code: [Select]

qemu-img create -f qcow2 -b Android_Devel_VM.hdd Android_Devel_VM.delta

qemu-system-x86_64 \
  -name "Android_Devel_VM" \
  -drive file=Android_Devel_VM.delta \
  -net nic \
  -net user \
  -m 1024 \
  -usbdevice tablet \
  -enable-kvm \
  -vnc :1 \
  -vga vmware

It seems that it does not support Chinese character in edit field.

Maybe because of the input method of Chinese, as we key in 'wen' first,, the edit field will appear 'wen' with underline, then we pick one Chinese character from the list, and then the right Chinese character would show up in the edit field.

Lazarus seems like that it does not support this kind of input method,so when we key in 'wen', the 'wen' will be right here, we can't pick Chinese character any more.

Maybe it's the reason that  Lazarus treat a string by character one by one, if it can treat a string just like a string, it will be better.

It seems that it does not support Chinese character in edit field.

Which edit field? Running in Android or in the IDE in Linux?

I managed to download and install the virtual machine. Lazarus open the example project, when I do modifications and rebuild it, open the terminal windows and issue the command "ant debug" nothing happens. The output is as follows:

BUILD SUCCESSFUL

I do not know why ant does not see changes in the code
My expertise in Linux is 0

[felipemdc]

Did you test the APK and really check that it didn't reflect your changes?

[IndianaJones]

I know, it is nonsense but can you remove the bin directory (sudo rm -rf bin) and execute the command again. (ant debug)

[joseme]

To Felipe: yes I checked the APK and it's unchanged.
To Indiana: I will try your idea.
Thanks everybody!

[joseme]

Nonsense sometimes is the right option. I removed the entire bin directory and everything is OK. Thanks!!!

yes, i running in android.

[felipemdc]

yes, i running in android.

Ok, so it is expected. I haven't yet finished KeyPress support, so I am aware of various issues with it. KeyDown/KeyUp are very easy in Android, but KeyPress is very hard and underdocumented.

Edit: Try rev 34571 Now I added a new keychar implementation which hopefully should work for chinese. Now the only issue I know with text input is that when longclicking in the virtual keyboard it inputs both the face key and the selected key. No idea why it is inputing the face key too. But probably this doesn't affect chinese input.

Sorry, could you please specifically explain how to 'rev 3451'? Actually I don't know what is 'rev', my English is poor

[BigChimp]

Rev=revision, in this case the revision in the Subversion version control system used by FPC and Lazarus...

See e.g. the Wiki for documentation on how to use subversion (hint: something like: cd <lazarusdir>; svn update; make)

[mdalacu]

Thank you, the VM is working just fine. I have also had to delete the bin folder in order to generate a new apk.
