Android Question How to eject USB disk

[cxbs]

Hello everyone!

After copying files to the USB disk, if you force the USB disk to be removed, a 0 byte file will be produced. So you want to pop up the USB disk by programming. Here is the source code found on the Internet. I don't know how to convert it to ba4

Hope to get help, thank you!

public void doUnMountU() {
        IMountService service = IMountService.Stub.asInterface(ServiceManager.getService("mount"));
        try {
            service.unmountVolume(App_DataPara.getApp().GetExternalStorageDirectory(), true, false);
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }

App_DataPara.getApp().GetExternalStorageDirectory() It is the file directory of the U disk that needs to be unloaded. String type

You can call this code with inline java. You will need to find the package names and add them with imports.

Hello, Erel
I'm not familiar with Java. I tried to embed Java, but I didn't define imountservice and servicemanager. I tried to use import android.os.ServiceManager; But it still can't be edited

This is a private API so it is a bit difficult to find it, however with a Google search: https://android.googlesource.com/pl...re/java/android/os/storage/IMountService.java

import android.os.storage.*;
