error while compiling app text to speech demo

When I have tried to compile

everything was OK. But when I have tried to compile Text to speech demo, I have got series of errors while compiling with javac. I have attached The file.

LAMW with JSON

Hey guys, I think i discovered a bug in LAMW. Whenever I try to retrieve data from a JSON object, the application crashes, and I receive the following message from logcat:

A/libc(30743): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)

I can do almost anything with a JSON object, and the application goes on. But when I try to access the fields of my JSON objects, one of the most crucial things within the application, the crash happens.

I don't know the reason yet, but I think the problem may be general for all LAMW users. Because of that, I've made a smaller application that reproduces the error, here is the unit for it:

unit testgui;

{$mode delphi}

  Classes, SysUtils, And_jni, And_jni_Bridge, Laz_And_Controls, 
    Laz_And_Controls_Events, AndroidWidget, fpjson, jsonparser, fpjsonrtti;

      vdst.CaseInsensitive:= true;
      vmyo:= TMyObj.Create;
      vja:= TJSONArray(GetJSON(json));
      vjo:= vja.Objects[0];

jBluetoothClientSocket

Here's the deal, I'm using the Bluetooth components in a demo application, which will serve as the foundation of a bigger application, which may turned into a commercial application in the future(who knows). Everything was OK, I was able enable the Bluetooth of the device, search for paired devices on the vicinity, and connect to one of the devices. But was after that where the problems started to begin.

First: the application was unable to disconnect from the other device using jBluetoothClientSocket.Disconnect(). I assured that a device should be connected before calling this method, and set the application to inform the user if connection was terminated. But after the call, the other device keep telling me that the connection was active, and due the nature of Bluetooth, this shouldn't be true if the method was successful.

Second:The other device didn't received data sent from the application using jBluetoothClientSocket.Write(), and the application was able to retrieve the data using jBluetoothClientSocket.Read either. And I also had ways to assure and measure if the other device had sent or received data.

I don't know if I'm misusing the components, but they seemed intuitive, so I worked with what I had. But I'm certainly misguided, because LAMW has little to no documentation, and that may had been the cause of these inconsistencies.

Thank you in advance for any help.

jLocation doesn't work if GPS was not enabled at startup

If GPS was initially (before starting the app) disabled, then jLocation will never call back with phone location nor GPS status / satellites.

How to reproduce with AppLocationDemo1 demo:

1. Close apps, disable GPS.
2. Start AppLocationDemo1 (don't press any button)
3. Enable GPS in phone Settings.
4. Press 'Try Start Tracker' button in demo app.
5. The app will return a message 'GPS is On! Starting Tracker...' but will never call any of the jLocation events.

error while compiling Alarm manager sample app

Finally here is detailed log about compilation. I AM helpless to find The cause myself. I have installed all SDK platform tools needed, including Android API 17. Unfortunately, more than 1 or 2 sample projects can not be compiled. I Am also using ANDROID NDK R10E. Or should I use lover supported version instead?
I know, that I AM bothering you but I can not find The cause myself even by reading log carefully.

Why demos/*/bin folders are not cleaned?

version 0.8 can't find SDK build-tools folder on Linux

My SDK path is "/home/user/android/sdk"

android_wizard/androidwizard_intf.pas line 742 removes paths with "android" in them which filters out my path:

742: if ( Pos('W', auxStr) = 0 ) and ( Pos('rc2', auxStr) = 0 ) and (Pos('android', auxStr) = 0 ) then //escape some alien...

on OKAY - press (virt. keyboard) from a textfield a enter is send twice

The on enter event is triggered twice in my app, on a real device and on the emulator. Thanks & with best regards, Thomas.

Sample:
procedure TAndroidModule1.jEditText1Enter(Sender: TObject);
begin
Raten();
end;

procedure Raten is always called twice :-(

Clean up demos

Can we remove demos/*/gen folders?

[LAMW] Build and Run

Exactly this is not issue but a suggestion. When I build LAMW project it's run automaticaly on virtual device. Due to the limited resource of my komputer, so I need build only and not run. Here I make a little modification code at "...\lamw\ide_tools\amw_ide_menu_items.pas as bellow:

procedureBuildApkAndRun(Sender: TObject);
var
Project: TLazProject;
begin
Project := LazarusIDE.ActiveProject;
if Assigned(Project) and (Project.CustomData.Values['LAMW'] <> '') then
try
IDEMessagesWindow.BringToFront;
with TApkBuilder.Create(Project) do
try
if LazarusIDE.DoBuildProject(crRun, []) <> mrOk then
raise Exception.Create('Cannot build project');
if BuildAPK then
begin
// Little modification to have a chance
if MessageDlg('RUN', 'Run Android Apps (APK).?' +
sLineBreak + 'Make sure your android virtual device running on your computer',
mtConfirmation, [mbYes, mbNo], 0) = mrYes then**
RunAPK;
end;
finally
Free;
end;
except
on e: Exception do
IDEMessagesWindow.SelectMsgLine(
IDEMessagesWindow.AddCustomMessage(mluFatal, '[' +
e.ClassName + '] Failed: ' + e.Message, '', 0, 0, 'Exception'));
end
else
ShowMessage('The active project is not LAMW project!');
end;

I'm sorry if this is wrong place. I don't know how to request this suggestion.
Thank you.

android list avds is deprecated, avds will not show in emulator on linux

Discussion about this issue here: http://forum.lazarus.freepascal.org/index.php/topic,42798.msg299155.html#msg299155

In short, android list avds command is deprecated and the avds items are not being shown in the emulators list.

¨Speech to text unit issue

I have tested Speech to text and I have found out very interesting fact.
When I have declared Input variable as Unicodestring
The line of code
Input := jSpeechToText1.SpeakOut(intentData);
Return always only one word. So even if I have spoken more than one words, this variable contain only one word.
Is it possible to store more than one words after using
Input := jSpeechToText1.SpeakOut(intentData);
Or it is internal issue of Android, that it is not possible to find better way for words storage inside variables? Or do I had to use other variable type not Unicodestring?
Because I must test The recognized result in if then condition blocks.
Thank you very much for yours help and support.

Barcode & QR Code Component Please

Barcode & QR Code Component Please

jShellCommand

I tried to make my own example here using jShellCommand and nothing. The application builds and installs all right, but when it tries to run, a white screen appears and a warning from android, saying that the application has stopped working, just remove this component of the application that it works right, does anyone could tell me why this happens?

some advices how to create forms without using form designer

Because you are very friendly and highly hard working developers, who do their best to make this project working, I have one constructive plea to you.
I have found out, that I can not really use Form designer to create forms. FPCJVM compiler lack support of Pointers when calling .so native C libraries, so it is also not good way to make good app which calls .so libraries. And Lamw projects compile many .pas sources directly to machine processor code so speed is much more faster. So I have first plea.
How to correctly specify The object ID when creating .lfm file?
Can I simply specify ID from 1 to 20?
Currently I have found out, that I can remove objects from forms from Lazarus IDE, but for example, I can not change text values of objects on A form. So I mostly use Akelpad text editor to work with forms.
I will try to make a collection of all possible objects types and I will create for example button.lfm, combobox.lfm files to have prepared all possible Lamw compatible Object types.
I will try to use copy and paste operations to build my .lfm form.
And commands in .lfm file
BackgroundColor = colbrDefault
Which values can be put instead of default? It is necessary to type Hexadecimal colour numbers? Or it would be possible to allow developers to simply type colour Adjectives and optional number values?
Such as red, blue, white, and other colour names.
Thank you very much for yours time and for yours answers.

Console apps should be accessible with Talkback

Whe have professional solution, which is capable to create nicely looked applications. But why console applications which uses commands such as writeln or readln can not be made accessible also with Talkback?
So also those apps would be compiled to standard.apk file and could be also executed from a Android launcher such as GUI apps.
I only do not know, if is it technically possible. How much programmers efford would it require to achieve this task.

Is it possible customizing the jListView component such as jCustomDialog?

How to integrate Android support to The Lazarus 2.0 32 bit package?

Would somebody of us give not only Me step by step instructions how to integrate Android support to Lazarus 2.0 so also Lamw will work correctly? Now, I AM getting error when I want to use Lamw create package command by pressing CTRL+F1.
What would I had to do to get Lamw and also Android work by using Lazarus 2.0? I have even tried to use Lamw commands
Get FPC Source [Trunk]
Build FPC Cross Android
But I have got errors after compilation related to Lazarus packages. So what should I do?

gradle_local_build.sh and gradle_local_run.sh don't work (linux)

android_wizard/androidwizard_intf.pas line 2088 and 2101 have a .\ in front of gradle which prevent it from running:

2088: strList.Add('.\gradle clean build --info');
2101: strList.Add('.\gradle run');

Since gradle is in the path, when I remove the .\ it works.

Bug while opening controls.lpi as project

When ever I want to open controls.lpi from every demo sample folder, I Am getting this bug.
"an" is an invalid integer.
Press OK to ignore and risk data corruption.
Press Abort to kill the program.
OK, storno.
When I press OK, there is no issue. I can create .apk package and resulting app is running on Android device like a charm. May be, that this little bug could be fetched as non remarkable. Or do you think, that it would be good idea to think about it?
My configuration.

Thank you for yours programmers analysis of this little issue.
May be, that it is caused by something inside my Windows, I do not know.

Why "-o" compiler option is in two places:

1. androidwizard_intf.pas:1351-1354 - Custom options,
2. androidwizard_intf.pas:1425 - AProject.LazCompilerOptions
   ???
   I think it should be removed from custom options.

System.ChDir should not be used

ChDir blocks directory by Lazarus (it cannot be removed etc.)
If ChDir is used only for check directory existence, it should be replaced by DirectoryExists(Utf8).
Maybe commenting out androidwizard_intf.pas:1470?

Layout library for visually impaired programmers

How complex would be to create Pascal Unit, which would be used to create APP GUI without specifiy pixel values?
How complex would be to create algorithm, which would try to position objects automatically?

How to store data from voice recognition to string variable?

I have decided to bypass GUI creation by simply using voice recognition engine. But I Am helpless to find The way how to test which string have been stored to some variable.
I do not know how to convert data stored in The variable type jObject);
Showmessage write out recognized text but I need to have this text stored in some variable, where I can make congition blocks to test The content of this variable so program will be able to perform AN actions according to recognized value from VOice recognition engine from Google.
But how to do that? If it is currently not possible, please try to consider adding some function or procedure, which will support also string variables or other data type, which can be used inside condition blocks.

jSpeechToText1.SpeakOut(input);
But which data type should I assign to input variable, because when I construct this command, It support only pointer variable data type.

Copy&paste does not assign new IDs

When copying eg. jEditText its ID (visible in lfm) does not change. This is a bug because then Anchor based sizing and positioning does not work as expected.

Quick fix: Make ID visible in object inspector to change it manually.
Better fix: Generate new ID when copied. Then traverse all controls and ensure they have unique ID.

jForm fixed size

Why the size of jForm is fixed (hardcoded as 300x600, see androidwidget.pas:1819-1823)?

Lazarus on Ubuntu 14.04 64

Collect data for use in the lamw on Lazarus 1.4 and FPC 3.0.1 installed on Ubuntu 04.14 64-bit .

Build in Lazarus / Gradle Linux "--info"

Ubuntu 16.04 / x64. Lazarus 2.0.2, FPC 3.0.4.

2 issues.

1. Can't parse "--info" of gradle clean build --info. I worked around it by commenting out --info as a param in apkbuild.pas.

2. Sans --info param though gradle does not try to build in the Project Directory. The terminal pops up, runs gradle, completes 1 task and exits.

A couple of suggestions. Is there any reason gradle isn't used for the entire build process? I also want to mention that a lot of the sh scripts will not work. Ubuntu defaults to dash not bash. Shebang line would help but even something as simple as source in this these scripts needs to be . not source command. The paths are wrong as well. Simple scripts such as install debug apk have the wrong path to the apk.

I have one script in .local/bin

that will do the same

#!/usr/bin/env bash

debug_apk_dir=$(pwd)/build/outputs/apk/debug/
debug_apk=$(find $debug_apk_dir -name "*.apk")

adb install -r $debug_apk

Despite that. Thank you for the great work. I build the APK on the CLI without issue. It would be nice to build in the IDE though.

AudioRecord example

Can someone please provide a simple AudioRecord binding / example?

Many thanx in advance!

Application crash

Hi, while I was developing an application, I've tried to implement a exception handler that writes a log file whenever an unhandled exception is raised, such file should contain the information of the exception. The code for the handler his like this:

function DumpExceptionCallStack(E: Exception): string;
var
  I: Integer;
  Frames: PPointer;
  Report: string;
begin
  Report := 'Program exception! ' + LineEnding +
    'Stacktrace:' + LineEnding + LineEnding;
  if E <> nil then begin
    Report := Report + 'Exception class: ' + E.ClassName + LineEnding +
    'Message: ' + E.Message + LineEnding;
  end;
  Report := Report + BackTraceStrFunc(ExceptAddr);
  Frames := ExceptFrames;
  for I := 0 to ExceptFrameCount - 1 do
    Report := Report + LineEnding + BackTraceStrFunc(Frames[I]);
  result := Report;
end;  

procedure TAndroidModule1.CustomExceptionHandler(Sender: TObject; E: Exception);
var
  s,z: String;
begin
  s:= DumpExceptionCallStack(E);
  z:= FormatDateTime('dd_mm_yy__hh_nn_ss',Now);
  jTextFileManager1.SaveToFile(s,'log_'+z+'.txt');
  Self.CopyFile(Self.GetEnvironmentDirectoryPath(dirInternalAppStorage)+'/log_'+z+'.txt',
                Self.GetEnvironmentDirectoryPath(dirDownloads)+'/log_'+z+'.txt');
end;   

And also, to make the application use this handler, I've done this:

gApp.OnException:= TAndroidModule1.CustomExceptionHandler;

The CustomExceptionHandler works fine when I call it, creating and writing a log file for an exception that I have passed, but when I do this:

procedure TAndroidModule1.jButton1Click(Sender: TObject);
begin
  raise Exception.Create('Testando exceção');
  //CustomExceptionHandler(Sender,Exception.Create('Testando exceção')); //works fine
end; 

the application crashes and no log file is written nor created. What should be the reason of this?

Designer

I'm going to change default color of jForm to (R:240,G:240,B:240), that is default for Android 4.2.2 (api17). Why it is black? Draft classes should be also reworked for white background drawing.
Any objections?

Hi, is there a way to open a password protected sqlite db?
Thanks a lot, Thomas.

Is it possible to load and use .so library in Lamw projects on Android 4.1.2?

Dear specialists,
I have worked with one older Lamw based project. Its aim was to provide simple Internet radio player, which have used bass.so for Android.
Project is still working smoothly on modern devices, but it is not possible to use bass.so on older devices. Developer of bass.so have confirmed Me, that his library should even work with lover versions of Android than 4.1.2. And here is The core of my question.
Is it possible to call and use other .so libraries when using Lamw project on Android 4.1.2? Do you think, that it would be necessary to modify Lamw modules so some hack had to be done to support Android 4.1.2 while using .so libraryes?
To test it. Does somebody of you know about some Lamw compatible project, which uses at least one .so library so I could try it with Android 4.1.2?
I Am getting this bug when I want to use bass.so on Android 4.1.2 and I have done my best to use Lamw from yesterday. I had to combine two various versions of Lamw and two various versions of Lazandroid to be successfull and I had to type
ant release
command after use build command to be able to compile My project with latest Lamw. Sure, app is working on modern devices. But still crash perssists on Android 4.1.2
Here is bug
I/DEBUG ( 1252): signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr deadd00d
And here is one favourite little Radio player which I have compiled on Lazandroid latest stable by using Lamw version 0.8.3

https://github.com/r1me/LAMWBassStreamPlayback
Sure, I have also incorporated latest stable bass.so for Android. And thank you again. My sighted mother have told Me, that GUI which have created by Lamw are very attractive. Form based GUIS are containing nice frames. Very well done.

Space in project folder kills stat

Hi, the new version falis on adb stat on folder with spaces.
I hope this description helps!
Good luck!

The jHorizontalScrollView.java is Error!

In jHorizontalScrollView.java file , The two variable “lgravity” and "lweight" are not defined.
Please check and fix them , thank you!

Project name can be changed only for once

I have found one interesting property of Lamw modules.
When I use project options dialog window, when I choose Lamw dialog, there is one editable field, which can be used to change project name. After changing its name, I press OK, and save all button. Project is correctly stored. But when I open controls.lpy, I can not change project name for The second time. I do not know, if is it cause because of The fact,that it is necessary to change some binary data files. It is only very little issue, but I have discovered it.
