Total time: 2 mins …我正在尝试将USB大容量存储设备安装到运行android的Raspberry Pi上.我遇到了这个答案,它展示了如何使用命令行ADB shell安装它.但问题是每次我的设备启动时都必须运行这些命令.我想在onCreate()我的发布活动中安装USB驱动器.这是代码:
//Here is the mount drive function which I called in onCreate of my activity.
private void mountDrive() throws IOException, InterruptedException {
Process mProcess = Runtime.getRuntime().exec("/system/xbin/su");
BufferedReader reader = new BufferedReader(new InputStreamReader(mProcess.getInputStream()));
DataOutputStream dos = new DataOutputStream(mProcess.getOutputStream());
dos.writeBytes("mkdir /mnt/usb\n");
dos.flush();
dos.writeBytes("mount -t vfat -o rw /dev/block/sda1 /mnt/usb\n");
dos.flush();
dos.writeBytes("exit\n");
//Read the response
String line, result = "";
while ((line = reader.readLine()) != null) {
result += line;
Log.d("CMD","RESULT:"+result);
}
reader.close();
dos.flush();
dos.close();
mProcess.waitFor();
} …
