*** ** * ** ***
Class that provides network traffic statistics. These statistics include bytes transmitted and received and network packets transmitted and received, over all interfaces, over the mobile interface, and on a per-UID basis.
These statistics may not be available on all platforms. If the statistics are not supported by this device, `https://developer.android.com/reference/android/net/TrafficStats#UNSUPPORTED` will be returned.
Note that the statistics returned by this class reset and start from zero after every reboot. To access more robust historical network statistics data, use `https://developer.android.com/reference/android/app/usage/NetworkStatsManager` instead.

### getUidTxBytes
Added in [API level 8](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static long getUidTxBytes (int uid)
```
Return number of bytes transmitted by the given UID since device boot. Counts packets across all network interfaces, and always increases monotonically since device boot. Statistics are measured at the network layer, so they include both TCP and UDP usage.
Before `https://developer.android.com/reference/android/os/Build.VERSION_CODES#JELLY_BEAN_MR2`, this may return `https://developer.android.com/reference/android/net/TrafficStats#UNSUPPORTED` on devices where statistics aren't available.
Starting in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#N` this will only report traffic statistics for the calling UID. It will return `https://developer.android.com/reference/android/net/TrafficStats#UNSUPPORTED` for all other UIDs for privacy reasons. To access historical network statistics belonging to other UIDs, use `https://developer.android.com/reference/android/app/usage/NetworkStatsManager`.
| Parameters ||
|---|---|
| `uid` | `int`
|
| Returns ||

### incrementOperationCount
Added in [API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static void incrementOperationCount (int operationCount)
```
Increment count of network operations performed under the accounting tag currently active on the calling thread. This can be used to derive bytes-per-operation.
| Parameters ||
|---|---|
| `operationCount` | `int`: Number of operations to increment count by.
|
### incrementOperationCount
Added in [API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static void incrementOperationCount (int tag,
int operationCount)
```
Increment count of network operations performed under the given accounting tag. This can be used to derive bytes-per-operation.
| Parameters ||
|---|---|
| `tag` | `int`: Accounting tag used in `https://developer.android.com/reference/android/net/TrafficStats#setThreadStatsTag(int)`.
|
| `operationCount` | `int`: Number of operations to increment count by.
|
### setThreadStatsTag
Added in [API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static void setThreadStatsTag (int tag)
```
Set active tag to use when accounting `https://developer.android.com/reference/java/net/Socket` traffic originating from the current thread. Only one active tag per thread is supported.
Changes only take effect during subsequent calls to `https://developer.android.com/reference/android/net/TrafficStats#tagSocket(java.net.Socket)`.
Tags between `0xFFFFFF00` and `0xFFFFFFFF` are reserved and used internally by system services like `https://developer.android.com/reference/android/app/DownloadManager` when performing traffic on behalf of an application.
| Parameters ||
|---|---|
| `tag` | `int`
|
**See also:**

### setThreadStatsUid
Added in [API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static void setThreadStatsUid (int uid)
```
Set specific UID to use when accounting `https://developer.android.com/reference/java/net/Socket` traffic originating from the current thread. Designed for use when performing an operation on behalf of another application, or when another application is performing operations on your behalf.
Any app can *accept* blame for traffic performed on a socket originally created by another app by calling this method with the `https://developer.android.com/reference/android/system/Os#getuid()` value. However, only apps holding the `android.Manifest.permission#UPDATE_DEVICE_STATS` permission may *assign* blame to another UIDs.
Changes only take effect during subsequent calls to `https://developer.android.com/reference/android/net/TrafficStats#tagSocket(java.net.Socket)`.
| Parameters ||
|---|---|
| `uid` | `int`
|

```
public static void untagSocket (Socket socket)
```
Remove any statistics parameters from the given `https://developer.android.com/reference/java/net/Socket`.
In Android 8.1 (API level 27) and lower, a socket is automatically untagged when it's sent to another process using binder IPC with a `ParcelFileDescriptor` container. In Android 9.0 (API level 28) and higher, the socket tag is kept when the socket is sent to another process using binder IPC. You can mimic the previous behavior by calling `untagSocket()` before sending the socket to another process.
| Parameters ||
|---|---|
| `socket` | `Socket`: This value cannot be `null`.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/java/net/SocketException` | |
