Native method not found: com.fazecast.jSerialComm.SerialPort.openPortNative:()J

[mtotaro]

Hi,

Opening ports, or reading bytes. The issue is that it couldnt locate the native jSerialComm shared library.

In SerialPort.class is always failing in this line:

line 707: if (fileContents == null) { System.err.println("Could not locate or access the native jSerialComm shared library."); System.err.println("If you are using multiple projects with interdependencies, you may need to fix your build settings to ensure that library resources are copied properly."); }

and before that

try { InputStream fileContents = SerialPort.class.getResourceAsStream("/" + libraryPath + "/" + fileName); if (fileContents == null && isAndroid) { libraryPath = libraryPath.replace("Android/", "lib/"); fileContents = SerialPort.class.getResourceAsStream("/" + libraryPath + "/" + fileName); }

this line : fileContents = SerialPort.class.getResourceAsStream("/" + libraryPath + "/" + fileName);

is returning always null.

libraryPath is lib/armeabi, and filename is libjSerialComm.so

Can somebody help me please?

[hedgecrw]

It sounds like somehow the jSerialComm native binaries aren't getting copied into your Android installation (APK) file. Can you open that file and verify that the binaries are contained in there? If they are missing, it's some sort of Android build configuration issue, but I'm not an expert on building/configuring for Android, nor is this library completely supported on Android any more since they keep tightening down security for filesystem access of third-party libraries.

[mtotaro]

Yes they are there!. I am trying to configure Gradle, in order to load the files. Apparently now he is loading them, but he throws the following error:

I suppose he charges it but he charges it badly.

Any ideas on how to properly compile the files?

This is my gradle:

Hmmm the cmakeraw error is a native OS system call, so give me a minute to look into why that could possibly be throwing an error.

[mtotaro]

I had to create a jniLibs Folder and extracted all the folders of .jar and put it there. that's why in my gradle is

sourceSets { main { jniLibs.srcDirs = ['lib'] } }

But well im trying all things to get it work.

[hedgecrw]

OK, so it looks like more recent Android systems removed cmakeraw from their libC implementations. I inserted my own version, so please test the following code and let me know if it works:

https://www.dropbox.com/s/b0ojhbwf82qnmlc/jSerialComm-2.4.1.jar?dl=0

You may need to extract its contents to overwrite what you have in jniLibs. Please post back if that works.

[hedgecrw]

Perfect, that's basically the same problem as cmakeraw - looks like Android removed all tc* functions.

Try this one: https://www.dropbox.com/s/so22e6t4nnw7noc/jSerialComm-2.4.1-beta.jar?dl=0

[mtotaro]

Its seems to be working now, but when i do the following:

SerialPort test[]= SerialPort.getCommPorts();

I got nothing.

The min target is API 24. Could that be the error or making some trouble?

[hedgecrw]

Hmmm...probably not, but no idea - Like I said, Android is a moving target when it comes to device libraries. 1) Is your device rooted, 2) I don't think anything enumerates on Android without the device you're trying to talk to already physically connected, and 3) if the device you're trying to talk to doesn't natively show up as a serial port in Posix/Linux (like a USB-to-Serial converter), then it won't show up in this library either.

[mtotaro]

I understand, i tried with a targetversion 17, and im getting /dev/ttyACM0. But im having issues with sending commands to my device attached.

[mtotaro]

1) Is not rooted 2) Its connected 3) Have you tried to get this work on android 8.1?

[mtotaro]

I was wondering if this is a issue of permission? Could it be that i need to know if my device is attached or not?

[mtotaro]

There is something i want to ask you. Is there by any chance that i can add like my own list of USBProber? Something like this:

probeTable.addProduct(0x11CA, 0x0220,Ch34xSerialDriver.class);

Because your driver dont recognize my device.

[hedgecrw]

The problem is most likely that your device is not rooted. More recent Android devices do not allow direct access to their serial ports (emulated or otherwise) on non-rooted devices, but instead require that you go through the Android USB API. This has been a sticking point with providing support for Android in this library, since it is a serial port library and not a USB one. If you are trying to communicate with a USB-based device using non-rooted Android, you will most likely have to use a library designed to be used specifically for that purpose, unfortunately.

[hedgecrw]

Closing this issue. The bug portion of the issue has been fixed, and the non-bug portion (using the library on a non-rooted Android device) is not supported at this time.
