Android finally has the app permission system it should have had all along.

Tap one of the apps in the list to view more information. This shortcut may not be present on every Android device as different devices use different interfaces tweaked by their manufacturers and carriers. Older Android apps automatically get these permissions when you install them, but you can revoke any permission you want from here. Denying permission may cause it to no longer function as intended.

Most of the time, applications should just continue working normally if you revoke their permissions. In other cases, an application may just not function normally. Either way, if you encounter a problem with an app, you can always come back to this screen and grant it these permissions again. This can give you a better idea of what an app is actually doing with those permissions.

Android now hides these more fine-grained permissions. To view and manage all app permissions at once, go to the list of apps by opening the Settings screen and tapping Apps. To view the apps that have access to each type of data or sensor and control this, tap a category. For example, to see which apps have access to your calendar information, tap Calendar. To prevent an app from accessing your calendar information, disable it on the Calendar permissions screen.

We performed this process with Android 6. Android manufacturers often modify the interface on their devices, and some options may be in different places.

Want to know more?The purpose of a permission is to protect the privacy of an Android user. Android apps must request permission to access sensitive user data such as contacts and SMSas well as certain system features such as camera and internet. Depending on the feature, the system might grant the permission automatically or might prompt the user to approve the request. A central design point of the Android security architecture is that no app, by default, has permission to perform any operations that would adversely impact other apps, the operating system, or the user.

This includes reading or writing the user's private data such as contacts or emailsreading or writing another app's files, performing network access, keeping the device awake, and so on. This page provides an overview to how Android permissions work, including: how permissions are presented to the user, the difference between install-time and runtime permission requests, how permissions are enforced, and the types of permissions and their groups.

If you just want a how-to guide for using app permissions, instead see Request App Permissions. For example, an app that needs to send SMS messages would have this line in the manifest:. If your app lists normal permissions in its manifest that is, permissions that don't pose much risk to the user's privacy or the device's operationthe system automatically grants those permissions to your app.

For more information about normal and dangerous permissions, see Protection levels. Only dangerous permissions require user agreement. The way Android asks the user to grant dangerous permissions depends on the version of Android running on the user's device, and the system version targeted by your app. If the device is running Android 6. Your app must ask the user to grant the dangerous permissions at runtime. When your app requests permission, the user sees a system dialog as shown in figure 1, left telling the user which permission group your app is trying to access.

The dialog includes a Deny and Allow button. If the user denies the permission request, the next time your app requests the permission, the dialog contains a checkbox that, when checked, indicates the user doesn't want to be prompted for the permission again see figure 1, right. Figure 1. Initial permission dialog left and secondary permission request with option to turn off further requests right.

If the user checks the Never ask again box and taps Denythe system no longer prompts the user if you later attempt to requests the same permission. Even if the user grants your app the permission it requested you cannot always rely on having it.

In Android 6, the user has finally! However, I couldn't find a way to approve or deny network access, either via Wi-Fi or via cellular data connection. The relevant permission appears in "Other app capabilities" and it's only informative -- apparently there's no way to change it. Normal permissions cover areas where your app needs to access data or resources outside the app's sandbox, but where there's very little risk to the user's privacy or the operation of other apps.

For example, permission to set the time zone is a normal permission. If an app declares in its manifest that it needs a normal permission, the system automatically grants the app that permission at install time. The system does not prompt the user to grant normal permissions, and users cannot revoke these permissions. Dangerous permissions cover areas where the app wants data or resources that involve the user's private information, or could potentially affect the user's stored data or the operation of other apps.

For example, the ability to read the user's contacts is a dangerous permission. If an app declares that it needs a dangerous permission, the user has to explicitly grant the permission to the app. Surprising or not, the following permissions comes under the list of Normal Permissions :. If that doesn't suffice, checkout the permissions managed by AppOps here. If you don't find your permission listed there, you won't be able to do anything with it in GUI.

You could use NetGuard see my list of Internet Firewalls for other alternativeswhich works without root and lets you block internet access for apps selectively WiFi or mobile data, and even always or only if screen is off.

Before you add networking functionality to your app, you need to ensure that data and information within your app stays safe when transmitting it over a network. To do so, follow these networking security best practices:.

For more information on applying secure networking principles, see Android's networking security tips. You can also check out the Android NetworkConnect sample.

On devices running Android 9 and lower, the platform DNS resolver supports only A and AAAA records, which allow looking up the IP addresses associated with a name, but does not support any other record types.

Note that parsing the response is left to the app to perform. To avoid creating an unresponsive UI, don't perform network operations on the UI thread. By default, Android 3. The following Activity snippet uses a headless Fragment to encapsulate asynchronous network operations.

Later, you will see how the Fragment implementation, NetworkFragmentaccomplishes this.

Your Activity should also implement the DownloadCallback interface, allowing the fragment to call back to the Activity in case it needs connectivity status or needs to send an update back to the UI.

At the minimum, your DownloadCallback interface can consist of the following:. Now, add the following implementations of the DownloadCallback interface methods to your Activity :. Since the NetworkFragment runs on the UI thread by default, it uses an AsyncTask to run the network operations on a background thread.

This Fragment is considered headless because it doesn't reference any UI elements. Instead, it is only used to encapsulate logic and handle lifecycle events, leaving the host Activity to update the UI. When using a subclass of AsyncTask to run network operations, you must be cautious that you don't create a memory leak in the case where the Activity that is referenced by the AsyncTask is destroyed before the AsyncTask finishes its background work.

To ensure this doesn't happen, the following snippet clears any references to the Activity in the Fragment's onDetach method. Now, you should implement a subclass of AsyncTask as a private inner class inside your Fragment :. In the snippet above, the doInBackground method runs in a background thread and calls the helper method downloadUrl. Once a connection has been established, you should use the method getInputStream to retrieve the data as an InputStream. Note that the method getResponseCode returns the connection's status code.

This is a useful way of getting additional information about the connection. A status code of indicates success. Once you get an InputStreamit's common to decode or convert it into a target data type. For example, if you were downloading image data, you might decode and display it like this:. In the example shown above, the InputStream represents the text of the response body. This is how you would convert the InputStream to a string so that the Activity can display it in the UI:.

So far, you have successfully implemented an Activity that performs a network operation. But, if the user decides to change the device configuration i. Thus, the network work done on the background thread will have been wasted. To persist through these configuration changes, you need to retain your original Fragment and ensure that the reconstructed Activity references it.When you are working on app which wants to access internet, you need to add extra permission in androidManifest.

If an app needs to use resources or information outside of its own sandbox, the app has to request the appropriate permission. You declare that your app needs a permission by listing the permission in the app manifest and then requesting that the user approve each permission at runtime on Android 6. This page describes how to use the Android Support Library to check for and request permissions.

The Android framework provides similar methods as of Android 6. For example, an app that needs to access the internet would have this line in the manifest:. The system's behavior after you declare a permission depends on how sensitive the permission is. Some permissions are considered "normal" so the system immediately grants them upon installation.

Other permissions are considered "dangerous" so the user must explicitly grant your app access. For more information about the different kinds of permissions, see Protection levels. If your app needs a dangerous permission, you must check whether you have that permission every time you perform an operation that requires that permission. Beginning with Android 6. So even if the app used the camera yesterday, it can't assume it still has that permission today. To check if you have a permission, call the ContextCompat.

For example, this snippet shows how to check if the activity has permission to write to the calendar:. Android provides several methods you can use to request a permission, such as requestPermissionsas shown in the code snippet below. Calling these methods brings up a standard Android dialog, which you cannot customize.

How this is displayed to the user depends on the device Android version as well as the target version of your application, as described in the Permissions Overview. In some circumstances, you want to help the user understand why your app needs a permission.

For example, if a user launches a photography app, the user probably won't be surprised that the app asks for permission to use the camera, but the user might not understand why the app wants access to the user's location or contacts.

Before your app requests a permission, you should consider providing an explanation to the user. Keep in mind that you don't want to overwhelm the user with explanations; if you provide too many explanations, the user might find the app frustrating and remove it.

One approach you might use is to provide an explanation only if the user has already denied that permission request.

Android provides a utility method, shouldShowRequestPermissionRationalethat returns true if the user has previously denied the request, and returns false if a user has denied a permission and selected the Don't ask again option in the permission request dialog, or if a device policy prohibits the permission.

If a user keeps trying to use functionality that requires a permission, but keeps denying the permission request, that probably means the user doesn't understand why the app needs the permission to provide that functionality. In a situation like that, it's probably a good idea to show an explanation. More advice about how to create a good user experience when asking for permission is provided in App Permissions Best Practices.

Some apps depend on access to sensitive user information related to call logs and SMS messages. If you want to request the permissions specific to call logs and SMS messages and publish your app to the Play Store, you must prompt the user to set your app as the default handler for a core system function before requesting these runtime permissions.

For more information on default handlers, including guidance on showing a default handler prompt to users, see the guide on permissions used only in default handlers. If your app doesn't already have the permission it needs, the app must call one of the requestPermissions methods to request the appropriate permissions.

Your app passes the permissions it wants and an integer request code that you specify to identify this permission request. This method functions asynchronously. It returns right away, and after the user responds to the prompt, the system calls the app's callback method with the results, passing the same request code that the app passed to requestPermissions. The following code checks if the app has permission to read the user's contacts.

If it does not have permission it checks if it should show an explanation for needing the permission, and if no explanation is needed, it requests the permission:. The prompt shown by the system describes the permission group your app needs access to, not the specific permission.
