I followed http://wiki.lazarus.freepascal.org/Custom_Drawn_Interface/Android#Step_4_-_Creating_the_APK_package_in_Windows, with the latest svn from Lazarus. Here are the "bugs" when I try to build the apk for "example\androidlcl"
D:\Svendi\Lazarus\Android\androidlcl3tbn\android>call javac -verbose -classpath D:\Svendi\Lazarus\Programmes\android-sdk\platforms\android-15\android.jar -d bin\classes src\com\pascal\lclbtn\LCLActivity.java
src\com\pascal\lclbtn\LCLActivity.java:341: error: unmappable character for encoding Cp1252
localpaint.getTextBounds("├?qg", 0, 3, localbounds);
^
In this file you have a strange caracter on line 341
Deleting it (yep I know :)) and trying to relauch ends with http://pastebin.com/MQmy5cpK

It is not a bug in my code, Java should not do that conversion of Unicode->CPsomething. Maybe we are missing some kind of option for javac which will tell it to use Unicode only.
Your Windows is for which language?
-
french. why would it be related with the windows french languague ? I did check the java gile it's encoded in UTF8 (see the file)
lclwidth = lclwidth + (3 * lcltextsize) / 16;
// Don't use just localbounds.height() from the source text
// because it will calculate the minimum necessary height,
// but we can't easily use that to draw text because it draws relative to the baseline
localpaint.getTextBounds("Ãqg", 0, 3, localbounds);
lclheight = localbounds.height();
and then why those all bugs ? (paste.bin)
-
french. why would it be related with the windows french languague ? I did check the java gile it's encoded in UTF8 (see the file)
The error comes from your Java JDK, in my computer there is no error. I have an polish Windows here. Why would it choose this particular encoding for the file? The JDK probably choose the Windows encoding to use for the file.
I read here: http://docs.oracle.com/javase/1.4.2/docs/tooldocs/windows/javac.html
And they say that there is a -encoding directory to javac. Could you try adding "-encoding utf8" or "-encoding utf-8" to the javac call in the batch file and see if this fixes the issue?
and then why those all bugs ? (paste.bin)
You are probably using a non-UTF-8 editor. Use Lazarus to open the file and you will see that the string is correct. You can also use a hexadecimal editor to check that it is correct.

No error with :
-verbose -classpath %APK_SDK_PLATFORM%\android.jar -d bin\classes -encoding utf8 src\com\pascal\lcltest\LCLActivity.java
I will add this to the wiki
Like I said there were others error (see the paste bin links after), this one occurs :

Strange, I never had so much trouble. It sounds like there is some problem with your javac ... but anyway if it works then maybe this can be ignored.
Could you post the 10 warnings too?
THIS TOOL IS DEPRECATED. See --help for more information.
There is no error here. It is just an information. They say it is deprecated but I am not aware of the new way that they recommend, so for now it will stay like that.

Pretty much the same I mentionned above
Deleting it (yep I know ) and trying to relauch ends with http://pastebin.com/MQmy5cpK
http://pastebin.com/s0zKJWVF
Hoping I did not make a silly syntax or path error
-
Ummm ... I have no idea personally, for me and for other people working with me it worked fine. Maybe because I have Windows XP 32 bits. Or maybe I am using an older JDK or older Android SDK...
Anyway, you should try Google too. There are lots of other people which have the same problem as you, and it is completely generic to Android, nothing Pascal specific here. Read:

v7 of what? JDK?
Building the apk : androidlcltest.apk

I/lclapp ( 1181): Trying to load liblclapp.so
E/lclapp ( 1181): WARNING: Could not load liblclapp.so
W/System.err( 1181): java.lang.UnsatisfiedLinkError: Couldn't load lclapp: findLibrary returned null
I think that the message is pretty clear. It cannot find liblclapp.so. Do you have that file in android/libs/armeabi/ from your project? liblclapp.so should be your compiled Pascal library file. If you change it's name you need to reflect that in the .java file.
Also make sure that in your main library project file you change the exported function names to reflect your Package Name.

Yes, I will add this to the wiki, v7 has some pb with android.
I think that the message is pretty clear.
Yep sorry it was a dumb question. And thks not to be angry.
I'm now Ok with androidlcl example : building under the latest lazarus, building apk, running on my android. I will write a short guide too if I'm allowed to. Just have these lines when building androidlcl'apk example, is it bad ? :
[checking com.pascal.lcltest.LCLActivity]
[loading java\lang\Error.class(java\lang:Error.class)]
For my own projetc, I think I have done all the checking with renaming for my project (lclbtn), here the error on logcat when I try to launch on Android :
E/AndroidRuntime( 7115): FATAL EXCEPTION: main
E/AndroidRuntime( 7115): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.pascal.lclbtn/com.pascal.lclbtn.lclbtn}: java.lang.ClassNotFoundException: com.pascal.lclbtn.lclbt
n in loader dalvik.system.PathClassLoader[/data/app/com.pascal.lclbtn-1.apk]
Why does it write .lclbtn.lclbtn ? Like a false renaming path or project ? I searched everywhere
Note : we have to change strings.xml in android\res\values too when building a new project, will add this too...

I don't see any error here. He just writes that it is loading a class.

ummm, maybe this one is wrong:
Look at your file android/src/pascal/lclbtn/LCLActivity.java
What does it's first line say? The original example says:
package com.pascal.lcltest;
In your case you should change the package name to your own.

I do that for a long time now :

I have LCLActivity.java with

Aha, now I see. Reading it carefully I can clearly recognize that it calls JNI_OnLoad and has issues there. See how it throws debug info writting in JNI_OnLoad:
I/lclapp (20374): JNI_OnLoad called
I/lclapp (20374): Reading our Activity Class
F/lclapp (20374): javaEnvRef^.FindClass failed <<<---- Error here
W/dalvikvm(20374): JNI_OnLoad returned bad version (-1) in /data/data/com.pascal.lclbtn/lib/liblclapp.so 0x4051d1e8
And now see the file lazarus/lcl/interfaces/customdrawn/customdrawnobject_android.inc:
line 487 javaActivityClass := javaEnvRef^^.FindClass(javaEnvRef,'com/pascal/lcltest/LCLActivity');
=/ Unfortunatelly there it is required the package name to find the activity class... so you need to change there too. And I can't think of how this could be done in a way as to not require this ...
It would be great if you could document in the wiki all the places that need to be changed, since I myself don't know actually =) Ideally some day the IDE should manage all of this.

In whixh section do you want me to post in the wiki ?

Yes, but I will change something. Having the package name in the LCL is very nasty... the LCL should be usable in any project without changes. I will make a routine in the .java file which returns the package name. Hopefully it will work, because JNI_OnLoad is very early.

Ok, strange that no one else did see that... I think I'm the first to build an apk with Lazarus 8-) ;)

Of course not, a couple of people must have done it, but they just never encounter such a problem or don't take the lazarus way of building andrid apps (I, for example, prefer FPC_JVM instead).

Ok, I commited my change here: http://svn.freepascal.org/cgi-bin/viewvc.cgi?view=rev&root=lazarus&revision=37099
Note that you will need to not only update your lcl but also do the small change in the .java file.
You should now write the package name in your main project file, like this:
library androidlcltest;
............
begin
CDWidgetset.ActivityClassName := 'com/pascal/lcltest/LCLActivity';
CDWidgetset.ActivityOnCreate := @MyActivityOnCreate;
end.
Please test if now you can use your project without altering the LCL

In fact , in China ,i have success build the androidlcltest APK at 28 February with Lazarus and it's work ok at my Lenovo Lepad A107. i also have finished write a Chinese guide to the Chinese Lazarus user.a lot of people have success build his androidlcltest APK at China.
To Felipe:
I have test the SVN 37100 androidlcltest , it's work fine at my Lenovo Lepad A107 .thank you great job!
sorry for my bad english!
