如何阅读的wpa_supplicant.conf文件 [英] how to read wpa_supplicant.conf file

问题描述

谁能帮我读通过Android应用编程在Android设备 /data/misc/wifi/wpa_supplicant.conf 文件。

Can anyone help me to read /data/misc/wifi/wpa_supplicant.conf file in android device through android app programmatically.

我试过低于code读取存储在的wpa_supplicant.conf 文件信息，并返回一个没有显示textview.but信息。

I tried the below code to read information stored in wpa_supplicant.conf file and display information in a textview.but it returns nothing.

try 
{

    Process psProc = Runtime.getRuntime().exec(new String[]{"su","-c"});//root
    File path=Environment.getDataDirectory();
    File myFile = new File("/data/misc/wifi/wpa_supplicant.conf");
    FileInputStream fIn = new FileInputStream(myFile);
    BufferedReader myReader = new BufferedReader(
    new InputStreamReader(fIn));
    String aDataRow = "";
    String aBuffer = "";
    while ((aDataRow = myReader.readLine()) != null) {
        aBuffer += aDataRow + "\n";
    }
    tv.setText(aBuffer);
    myReader.close();
    Toast.makeText(getBaseContext(),"Done reading SD 'TextAreaAppender.java'",
                Toast.LENGTH_SHORT).show();
}
catch (Exception e) 
{
    Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show();
    tv.setText(e.getMessage());
}

TextView中显示任何内容。

Textview displays nothing.

推荐答案

请确保您有重新挂载分区。否则，你无权进行读/写在这里。

Please make sure you have remount the partition. Otherwise, you have no permission to read / write here.

您可以尝试在该文件夹然后再进一步操作如下。

You can try following before further operation on that folder.

Runtime.getRuntime().exec("system/bin/mount -o rw,remount -t rootfs /data");
Runtime.getRuntime().exec("system/bin/chmod 777 /data/misc/wifi");
