    text
    copied!<p>I have created an encrypted .obb file using the jobb tool. I use the following code to mount the obb file:</p> <pre><code> public void mountExpansion() { final StorageManager storageManager = (StorageManager) getContext() .getSystemService(Context.STORAGE_SERVICE); String packageName = "name.of.the.package"; String filePath = Environment.getExternalStorageDirectory() + "/Android/obb/" + packageName + "/" + "main." + version + "." + packageName + ".obb"; final File mainFile = new File(filePath); if (mainFile.exists()) { Log.d("STORAGE", "FILE: " + filePath + " Exists"); } else { Log.d("STORAGE", "FILE: " + filePath + " DOESNT EXIST"); } String key = "thisIsMyPassword"; if (!storageManager.isObbMounted(mainFile.getAbsolutePath())) { if (mainFile.exists()) { if(storageManager.mountObb(mainFile.getAbsolutePath(), key, 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("STORAGE","--&gt;MOUNTED"); } else { Log.d("##", "Path: " + path + "; state: " + state); } } })) { Log.d("STORAGE_MNT","SUCCESSFULLY QUEUED"); } else { Log.d("STORAGE_MNT","FAILED"); } } else { Log.d("STORAGE", "Patch file not found"); } } } </code></pre> <p>I am getting the following output: <em>FILE: filePath Exists SUCCESSFULLY QUEUED</em></p> <p>But nothing inside <em>onObbStateChangeListener</em> is getting called. I am calling this function from a custom view and testing this on Nexus 4/ KitKat.</p> <p>What could be the reason for this behaviour?</p>
