Native c++ library cant work with kotlin but works with java
HELLO i have kotlin project.
In my project i have to use pos device.
Pos device works with sample java project but my project does not work.
i put all .so files in jniLibs folder
System.loadLibrary method is working but external functions not working
when i try to use external native functions i get this error
E/art: No implementation found for void com.example.alknakralar.comValina.comValina.setLogFile(java.lang.String) (tried Java_com_example_alknakralar_comValina_comValina_setLogFile and Java_com_example_alknakralar_comValina_comValina_setLogFile__Ljava_lang_String_2)
here is the code
if (valina == null) {
try {
valina = comValina()
} catch (e: Exception) {
Toast.makeText(this, "Failed to load native library. " + e.message, Toast.LENGTH_SHORT).show()
}
}
if (valina == null) return
try {
valina!!.setLogFile("debug-Valina.txt")
//valina!!.SetLogFile("debug-Valina.txt")
//valina!!.SetLogLevel(comValina.eComValinaLogLevel.DEBUG_LEVEL_NOTICE)
} catch (e: Exception) {
Log.i("avs", "sa 3$e")
}
this is my code valina!!.setLogFile("debug-Valina.txt") here is the error line
class comValina {
external fun setLogFile(LogFile: String)
private external fun SetLogLevel(LogLevel: Byte)
private external fun InitializeTcpServer(PortNumber: Short): Int
external fun Payment(amount: Int): Int
enum class eComValinaLogLevel constructor(val value: Byte) {
DEBUG_LEVEL_FATAL(0.toByte()),
DEBUG_LEVEL_ERROR(1.toByte()),
DEBUG_LEVEL_WARNING(2.toByte()),
DEBUG_LEVEL_NOTICE(3.toByte())
}
companion object {
init {
try {
System.loadLibrary("comValina-android-armeabi")
} catch (e: Exception) {
} catch (ex: UnsatisfiedLinkError) {
}
try {
System.loadLibrary("comValina-android-armeabi-v7a")
} catch (e: Exception) {
} catch (ex: UnsatisfiedLinkError) {
}
}
}
fun SetLogLevel(LogLevel: eComValinaLogLevel) {
SetLogLevel(LogLevel.value)
}
fun Initialize(portNumber: Short): Int {
return InitializeTcpServer(portNumber)
}
}
and this is library access class
what should i do ?
and here is the java codes
