我已经挂载了我的.obb文件，但如何获得资产的最终路径

Question

i have mounted an obb file and i got a path like this /mnt/obb/880f5ef6a6885d1b8937f9625be73850 , but how to get the final path to my assets ( myAssets folder in the .obb file)?

Also when i browse to this directory i find it empty !

I have used this method to mount my .obb file

 public void mountExpansion() {
        final StorageManager storageManager  = (StorageManager) getSystemService(STORAGE_SERVICE);



        String packageName = "com.example.android";
        String filePath = Environment.getExternalStorageDirectory()
                + "/Android/obb/" + packageName + "/" + "main."
                + xAPKS[0].mFileVersion + "." + packageName + ".obb";
        final File mainFile = new File(filePath);
        if (mainFile.exists()) {
            Log.d(TAG, "FILE: " + filePath + " Exists");
        } else {
            Log.d(TAG, "FILE: " + filePath + " DOESNT EXIST");
        }


        if (!storageManager.isObbMounted(mainFile.getAbsolutePath())) {
            if (mainFile.exists()) {
                if(storageManager.mountObb(mainFile.getAbsolutePath(), null,
                        new OnObbStateChangeListener() {
                            @Override
                            public void onObbStateChange(String path, int state) {
                                super.onObbStateChange(path, state);
                                Log.d("PATH = ",path);
                                Log.d("STATE = ", state+"");
                                expansionFilePath =   storageManager.getMountedObbPath(path);
                                if (state == OnObbStateChangeListener.MOUNTED) {
                                    expansionFilePath = storageManager
                                            .getMountedObbPath(path);
                                    Log.d(TAG,expansionFilePath+"-->MOUNTED");

                                } 
                                else {
                                    Log.d(TAG, "Path: " + path + "; state: " + state);
                                }
                            }
                        }))
                {
                    Log.d(TAG,"SUCCESSFULLY QUEUED");
                }
                else
                {
                    Log.d(TAG,"FAILED");
                }

            } else {
                Log.d(TAG, "Patch file not found");
            }
        }else {

        }





    }

I have this message on the log

FILE: /storage/sdcard0/Android/obb/com.example.android/main.1014001.com.example.android.obb Exists
SUCCESSFULLY QUEUED
/mnt/obb/880f5ef6a6885d1b8937f9625be73850-->MOUNTED

Thanks.

obbPath = Environment.getExternalStorageDirectory().getPath() + File.separator + "Android/obb/" + getPackageName() + File.separator + "main.3." + getPackageName() + ".obb";
storageManager = (StorageManager)getApplicationContext().getSystemService(Context.STORAGE_SERVICE);
m_filePathString = storageManager.getMountedObbPath(obbPath) + File.separator + filename;
