jnuis wont work after asking android for external storage permission why solutions

The Android operating system has a system of permissions that apps must request in order to access certain features or data on a device. One such permission is the "external storage" permission, which allows an app to read and write files to the device's external storage (such as an SD card).

However, some users have reported that their JNUIS (Jawaharlal Nehru University Indian Server) apps will not work properly after they have granted the app external storage permission. There are several potential reasons for this issue:

1. The JNUIS app may be using an outdated version of the Android SDK (Software Development Kit) that is not compatible with the version of Android running on the user's device. This can cause the app to crash or malfunction when it tries to access the external storage.

2. The app may be expecting a specific file or folder to be present on the external storage, but the file or folder is missing or has been moved. This can cause the app to crash or malfunction when it tries to access the external storage.

3. The app may be trying to access external storage on a device that does not have an SD card or other external storage option. This can cause the app to crash or malfunction as it is not able to access the external storage.

4. The app may be trying to access external storage in a way that is not allowed by the Android security model. This can cause the app to crash or malfunction as the Android operating system will not allow the app to access the external storage.

Solutions

1. Update the JNUIS app to the latest version, which may include updates to the Android SDK that will make it compatible with the version of Android running on the user's device.

2. Check for the missing file or folder and move it to the location where the app is expecting it to be.

3. If the device does not have an SD card or other external storage option, try using a cloud storage service such as Google Drive or Dropbox to store the files that the app needs to access.

4. Check the app's code, If the app is trying to access external storage in a way that is not allowed by the Android security model, update the app's code to comply with the Android security model.

5. If the problem still persists, contact the developer of the app for support. They may be able to provide more specific information about the problem and a solution.

In conclusion, JNUIS app not working after granting external storage permission can be caused by various reasons such as outdated version of app, missing file or folder, device not having external storage option, app trying to access external storage in a way that is not allowed by Android security model. The above solutions can help in resolving the issue.

The Android operating system's permission system is designed to give users control over what data and features apps can access on their device. When an app is installed, it may request certain permissions, such as the ability to access the device's camera, microphone, or external storage. Users can then choose to grant or deny these permissions to the app.

However, it is important to note that granting an app access to external storage does not give the app access to the entire external storage. It only allows the app to access its own designated storage directory on the external storage, known as the app-specific directory. This is a security measure to prevent apps from accessing other apps' data on the external storage without permission.

Another important aspect to consider is that while some apps may require the external storage permission in order to function properly, others may not. For example, a camera app may need the permission to save photos and videos to the external storage, while a simple calculator app may not. Therefore, before granting the external storage permission, it is important to consider whether the app actually needs it and whether the user is comfortable with the app having that level of access to their device.

It's also worth noting that an app may not function properly if the external storage is not available for any reason such as SD card is not mounted, the storage is full, or the storage is corrupted. In these cases, it is important to check the external storage and resolve the issue before trying to use the app again.

In addition, when an app is updated, it may request new permissions that it did not previously have. Therefore, it is a good idea to review the app's permissions after updating it to ensure that the user is still comfortable with the app having access to that data or feature.

In conclusion, the Android operating system's permission system allows users to control what data and features apps can access on their device. External storage permission allows apps to access their own designated storage directory on the external storage. It's important for users to consider whether an app actually needs the permission, check for external storage availability, and review the app's permissions after updating it to ensure that the user is comfortable with the app having access to that data or feature.
