1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Manifest () ``` Constructs a new, empty Manifest.
### Manifest Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Manifest (InputStream is) ``` Constructs a new Manifest from the specified input stream.
| Parameters || |------|-----------------------------------------------------------------| | `is` | `InputStream`: the input stream containing manifest data
| | Throws || |----------------------------------------------------------------------------|------------------------------| | [IOException](https://developer.android.com/reference/java/io/IOException) | if an I/O error has occurred | ### Manifest Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Manifest (Manifest man) ``` Constructs a new Manifest that is a copy of the specified Manifest.
| Parameters || |-------|-----------------------------------------| | `man` | `Manifest`: the Manifest to copy
| ## Public methods ### clear Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void clear () ``` Clears the main Attributes as well as the entries in this Manifest.
### clone Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Object clone () ``` Returns a shallow copy of this Manifest. The shallow copy is implemented as follows: ``` public Object clone() { return new Manifest(this); } ```

| Returns || |--------------------------------------------------------------------|----------------------------------------| | [Object](https://developer.android.com/reference/java/lang/Object) | a shallow copy of this Manifest
| ### equals Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean equals (Object o) ``` Returns true if the specified Object is also a Manifest and has the same main Attributes and entries.
| Parameters || |-----|--------------------------------------------| | `o` | `Object`: the object to be compared
| | Returns || |-----------|-----------------------------------------------------------------------------------------------------| | `boolean` | true if the specified Object is also a Manifest and has the same main Attributes and entries
| ### getAttributes Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Attributes getAttributes (String name) ``` Returns the Attributes for the specified entry name. This method is defined as: ``` return (Attributes)getEntries().get(name) ``` Though`null`is a valid`name`, when`getAttributes(null)`is invoked on a`Manifest`obtained from a jar file,`null`will be returned. While jar files themselves do not allow`null`-named attributes, it is possible to invoke[getEntries()](https://developer.android.com/reference/java/util/jar/Manifest#getEntries())on a`Manifest`, and on that result, invoke`put`with a null key and an arbitrary value. Subsequent invocations of`getAttributes(null)`will return the just-`put`value. Note that this method does not return the manifest's main attributes; see[getMainAttributes()](https://developer.android.com/reference/java/util/jar/Manifest#getMainAttributes()).
| Parameters || |--------|-----------------------------| | `name` | `String`: entry name
| | Returns || |--------------------------------------------------------------------------------|----------------------------------------------------| | [Attributes](https://developer.android.com/reference/java/util/jar/Attributes) | the Attributes for the specified entry name
| ### getEntries Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Map getEntries () ``` Returns a Map of the entries contained in this Manifest. Each entry is represented by a String name (key) and associated Attributes (value). The Map permits the`null`key, but no entry with a null key is created by[read(InputStream)](https://developer.android.com/reference/java/util/jar/Manifest#read(java.io.InputStream)), nor is such an entry written by using[write(OutputStream)](https://developer.android.com/reference/java/util/jar/Manifest#write(java.io.OutputStream)).
| Returns || |------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------| | [Map](https://developer.android.com/reference/java/util/Map)`<`[String](https://developer.android.com/reference/java/lang/String)`, `[Attributes](https://developer.android.com/reference/java/util/jar/Attributes)`>` | a Map of the entries contained in this Manifest
| ### getMainAttributes Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Attributes getMainAttributes () ``` Returns the main Attributes for the Manifest.
| Returns || |--------------------------------------------------------------------------------|---------------------------------------------| | [Attributes](https://developer.android.com/reference/java/util/jar/Attributes) | the main Attributes for the Manifest
| ### hashCode Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int hashCode () ``` Returns the hash code for this Manifest.
| Returns || |-------|-------------------------------------------| | `int` | a hash code value for this object.
| ### read Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void read (InputStream is) ``` Reads the Manifest from the specified InputStream. The entry names and attributes read will be merged in with the current manifest entries.
| Parameters || |------|----------------------------------------| | `is` | `InputStream`: the input stream
| | Throws || |----------------------------------------------------------------------------|------------------------------| | [IOException](https://developer.android.com/reference/java/io/IOException) | if an I/O error has occurred | ### write Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void write (OutputStream out) ``` Writes the Manifest to the specified OutputStream. Attributes.Name.MANIFEST_VERSION must be set in MainAttributes prior to invoking this method.
| Parameters || |-------|------------------------------------------| | `out` | `OutputStream`: the output stream
| | Throws || |----------------------------------------------------------------------------|------------------------------| | [IOException](https://developer.android.com/reference/java/io/IOException) | if an I/O error has occurred | **See also:** - [getMainAttributes()](https://developer.android.com/reference/java/util/jar/Manifest#getMainAttributes())
