| `https://developer.android.com/reference/java/io/IOException` |   |

### read

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int read ()
```

Reads a byte of data from this input stream. This method blocks if no input is yet available.

<br />

| Returns ||

```
public int read (byte[] b, 
                int off, 
                int len)
```

Reads up to `len` bytes of data from this input stream into an array of bytes. If `len` is not zero, the method blocks until some input is available; otherwise, no bytes are read and `0` is returned.

<br />

| Parameters ||
|---|---|
| `b` | `byte`: the buffer into which the data is read. <br /> |
| `off` | `int`: the start offset in the destination array `b` <br /> |
| `len` | `int`: the maximum number of bytes read. <br /> |

| Returns ||
|---|---|
| `int` | the total number of bytes read into the buffer, or `-1` if there is no more data because the end of the file has been reached. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/io/IOException` |   |

### read

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

public int read (byte[] b)
```

Reads up to `b.length` bytes of data from this input stream into an array of bytes. This method blocks until some input is available.

<br />

| Parameters ||
|---|---|
| `b` | `byte`: the buffer into which the data is read. <br /> |

| Returns ||
|---|---|
| `int` | the total number of bytes read into the buffer, or `-1` if there is no more data because the end of the file has been reached. <br /> |
