vittalk commented 4 years ago

I downloaded the libaums-master and opened it in android Studio 4.0.2 .. while trying to build it, I go this error. I am trying to compile this libaums so that I can try out the sample code included... Do I need to add libusb? if so please let me know where do I need to them and how. I am an IOS programmer and newbie to both Android and libaums. So any help will be much appreciated. thanks, -Vittal

Hi, Documentation for the libusb module is here: https://github.com/magnusja/libaums/tree/develop/libusbcommunication

If you build the whole project you need to download libusb and add it to your local.properties.

For example: https://github.com/magnusja/libaums/blob/develop/.travis.yml#L24-L26

HI Davide, Thank you. Your suggestion helped me to compile the code. But now I have a different problem. It fails to install, I get the conflicting provider error.. I have tried various suggestions from the internet.. none of them have worked.. Greatly appreciate any help.

Installation did not succeed. The application could not be installed: INSTALL_FAILED_CONFLICTING_PROVIDER

List of apks: [0] '/Users/vittal/AndroidStudioProjects/LIBAUMS_work/libaums-master/app/build/outputs/apk/debug/app-debug.apk' Installation failed due to: 'null'

Thanks and Best Regards, -Vittal

Do you have another app using libaums on that device?

Try deleting that part https://github.com/magnusja/libaums/blob/develop/storageprovider/src/main/AndroidManifest.xml#L10-L20

vittalk commented 4 years ago

Gentlemen, Thank you very much. I was able to compile and load the libaums. Greatly appreciated

Hi Davide, Magnus, Thank for your help. I am able to load the USB drive and display the directory contents.... I have another question to ask.

I need to read a JSON file stored in the USB flash drive. I am using Google's GSON library to read the json file and analyze the content. Below is the code. As you can see, 'reader' is used as a parameter to gson.fromJson(). and reader holds the content of the file extData.json. I've been trying to make this code work with your UsbFileInputStream but I am unable to do so. Any suggestions please? Greatly appreciate your help

try { // create Gson instance val gson = Gson()

// create a reader

 Reader reader = Files.newBufferedReader(Paths.get("extData.json"));
// ------------convert JSON file to map ----------
val map: Map<*, *> = gson.fromJson(reader, MutableMap::class.java)

val SID_tag : String = "SID"

// print map entries
for ((key, value) in map) {
    println(key.toString() + "  =   " + value)
    val tempString : String  = key.toString() + " = " + value
    Log.i("json file content:   ", tempString)
    if (key.toString() == SID_tag) {
        ssID.text = "SID: " + value.toString()
        Log.i("Found SID IS:----  ", value.toString())
    }

}

// close reader
reader.close()

} catch (ex: Exception) { ex.printStackTrace() }

Thanks and Best Regards, -Vittal

Hi Gentlemen, To summarize my request, I need to read and write a JSON file present in the USB stick. I might later need to copy and transfer files(for which you have sample code already available). I am using GSON now, I am open to use any other library if you can recommend..

Thanks and Best Regards, -Vittal
