Android Question JavaObject - Seem to i don't understand much here

[Culjko]

In attach SDK for Ciontek C10 android!

Dim jo As JavaObject = Me
jo.InitializeContext
Dim jo1 As JavaObject = jo.InitializeNewInstance("vpos.apipackage.PosApiHelper", Null) 'This work normaly

*Solution for printing UTF-8 on each printer without converting fonts, work faster then SDK converting
Dim newFont As Typeface
Dim textPrint As String = "Any text"
Dim stingheight As Int = 19

Dim bmp As Bitmap
bmp.InitializeMutable(360,stingheight+5)
Dim DravPage As Canvas
Dim fontsize As Int = 10


bmp.InitializeMutable(360,stingheight+5)
DravPage.Initialize2(bmp)
DravPage.DrawColor(Colors.White)
DravPage.DrawText(textPrint,0.1,stingheight+0.5,Typeface.MONOSPACE,fontsize,Colors.RGB(0,0,0),"LEFT")
Dim bitmap As B4XBitmap = DravPage.Bitmap

Log(jo1.RunMethod("PrintBmp", Array(bitmap)))
When i try like this app crash.
How to use this DSK?

1. You posted it in B4R libraries forum. I moved it to Android questions.
2. Please use [code]code here...[/code] tags when posting code.
3. Post logs as text.

[Culjko]

Thank you

 

[Culjko]

I am new, I start to programming in B4A from oct 27 2023

 

[Culjko]

I find this in arr

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="vpos.apipackage"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="16"
android:targetSdkVersion="25" />

<application
android:allowBackup="true"
android:label="@string/app_name"

</manifest>
How to add in manifest

 

[Culjko]

I think I find what is problem, I get this message
java.lang.UnsatisfiedLinkError: dlopen failed: /data/app/com.ciontek.ePos-2/lib/arm/libAndroid.so: has text relocations
but when i open apk that library is not in that folder
Ciontek_RAPID_DEBUG.apk\llib\armeabi\libAndroid.so
is that is problem how to place librarly on right place?

 

[Erel]

Based on the error message, it does find the so file but the so file needs to be updated.

Try to set the targetSdkVersion to 22 and see if it makes any difference.

 

[Culjko]

It looks like this will work like this, my next question is related to variables how to send them to methods?


Dim vposHelper As JavaObject
Dim IconsFont As B4XFont
Log(vposHelper.InitializeStatic("vpos.apipackage.PosApiHelper")) ' log = (Class) class vpos.apipackage.PosApiHelper
Log(vposHelper.RunMethod("getInstance",Null)) ' log = vpos.apipackage.PosApiHelper@4360004


Log(vposHelper.RunMethod("PrintSetVoltage", Array(75)))

'Dim initPtinter As JavaObject = vposHelper.InitializeNewInstance("java.lang.PrintInitException" ,Array(2,24,24,0x33))
Log(vposHelper.RunMethod("PrintInit", Null)) ' log = 0
Log(vposHelper.RunMethod("PrintCheckStatus", Null)) ' log = 0

Dim textstr As String = "This is single line"
Dim stingheight As Int = 19
Dim bmp As Bitmap

bmp.InitializeMutable(360,stingheight+5)
Dim DravPage As Canvas
Dim fontsize As Int = 10
bmp.InitializeMutable(360,stingheight+5)
DravPage.Initialize2(bmp)
DravPage.DrawColor(Colors.White)
DravPage.DrawText(textstr,0.1,stingheight+0.5,Typeface.MONOSPACE,fontsize,Colors.RGB(0,0,0),"LEFT")
Dim SingleLine As Bitmap = DravPage.Bitmap
vposHelper.RunMethod("PrintBmp", Array As Object(SingleLine)) ' log = java.lang.IllegalArgumentException:

' but got java.lang.Class<vpos.apipackage.PosApiHelper>
'Log(vposHelper.RunMethod("PrintStr", Array("Proba\n")))
'Log(vposHelper.RunMethod("PrintStart",Null))

 

[Culjko]

successfully

In the meantime, I started with simpler functions, such as sending a string to the print, but the program remains unresponsive for a while and then reports an error -1002 receive timeout

Dim printer As ciontekPrinter
printer.Initialize(Me,"printer")
printer.PrintString("- - - - - - - - - - - - - - - - - - - - - - - -\n")
printer.PrintStart

user manual reference:
public int PrintInit(int gray, int fontHeight, int fontWidth, int fontZoom)
public int PrintStr(String str)
public int PrintStart()

 

[Culjko]

Now i find aboud

next time i will use it
