public void onStart(Intent intent)
```
    从类复制的说明: Ability
    
    Called back when an ability is started for initialization (it can be called only once in the entire lifecycle of an ability).
    Most initialization operations should be performed by calling this method. For example, you can use the current method to call Ability.setMainRoute(java.lang.String) and Ability.addActionRoute(java.lang.String,java.lang.String) to set the main router and action router for a Page ability.
    
    覆盖:

    参数:
    
    intent - Indicates information carried when this ability is started. Note: For a Service ability, null is passed.

  - onSaveAbilityState
```
public void onSaveAbilityState(PacMap outState)
```
    从类复制的说明: Ability
    
    Saves temporary data and states of this ability. This method should be implemented by a Page ability.
    This method is called when the system determines that the ability may be destroyed in an unexpected situation, for example, when the screen orientation changes or the user touches the Home key. Generally, this method is used only to save temporary states.
    
    覆盖:
    
    onSaveAbilityState 在类中 Ability
    
    参数:
    
    outState - Indicates the PacMap object used for storing user data and states. This parameter cannot be null.

```
public void onRestoreAbilityState(PacMap outState)
```
    从类复制的说明: Ability
    
    Restores data and states of an ability when it is restored by the system. This method should be implemented by a Page ability.
    This method is called if an ability was destroyed at a certain time due to resource reclaim or was unexpectedly destroyed and the Ability.onSaveAbilityState(ohos.utils.PacMap) method was called to save its user data and states. Generally, this method is called after the Ability.onStart(ohos.aafwk.content.Intent) method.
    
    覆盖:
    
    onRestoreAbilityState 在类中 Ability
    
    参数:

  - onMemoryLevel
```
public void onMemoryLevel(int level)
```
    Called when the system has determined to trim the memory, for example, when the ability is running in the background and there is no enough memory for running as many background processes as possible.
    
    覆盖:
    
    onMemoryLevel 在类中 Ability
    
    参数:
    
    level - Indicates the memory trim level, which shows the current memory usage status.
  - onStop
```
public void onStop()
```
    从类复制的说明: Ability
    
    Called back before an ability is destroyed.
    This method indicates the end of the ability lifecycle. It can be executed after the ability calls the Ability.terminateAbility() method or the last ability slice of the ability calls the AbilitySlice#terminate() method. Generally, this method is used to clear resources.
    
    覆盖:
    
    onStop 在类中 Ability
  - onNewIntent
```
public void onNewIntent(Intent intent)
```
    从类复制的说明: Ability

    onBackPressed 在类中 Ability
  - onForeground
```
public void onForeground(Intent intent)
```
    从类复制的说明: Ability
    
    Called back when the state of an ability changes from BACKGROUND to INACTIVE.
    This is an intermediate state callback method. Generally, the system calls this method to refresh data status and then calls back the Ability.onActive() method.
    
    覆盖:
    
    onForeground 在类中 Ability
    
    参数:
    
    intent - Indicates information carried when the ability returns to the INACTIVE state.
  - onBackground
```
public void onBackground()
```
    从类复制的说明: Ability

    onBackground 在类中 Ability
  - onActive
```
public void onActive()
```
    从类复制的说明: Ability

```
public void onInactive()
```
    从类复制的说明: Ability
    
    Called back when an ability enters the INACTIVE state (an ability in this state is not interactive and may change to the BACKGROUND or ACTIVE state).
    INACTIVE is an intermediate state and does not last for a long period of time. Frequent switching between ACTIVE and INACTIVE is possible. Therefore, you can use this method to perform certain simple operations, for example, committing any changes.
    
    覆盖:

  - onStartContinuation
```
public boolean onStartContinuation()
```
    从接口复制的说明: IAbilityContinuation
    
    Asks a user whether to start the migration.
    This method is called back when a local ability initiates a migration request.
    
    If the Ability does not implement this method, this Ability cannot be migrated, and false is returned. If the AbilitySlice does not implement this method, it does not affect whether its host ability can be migrated, and true is returned by default.
    
    指定者:
    
    onStartContinuation 在接口中 IAbilityContinuation
    
    返回:
    
    Returns true if the user allows the migration; returns false otherwise.

```
public void onCompleteContinuation(int code)
```
    从接口复制的说明: IAbilityContinuation
    
    Called back when a local ability migration is complete.

    指定者:
    
    onCompleteContinuation 在接口中 IAbilityContinuation
    
    参数:
    
    code - Indicates the migration result code. The value 0 indicates that the migration is successful, and -1 indicates that the migration fails.

```
    从接口复制的说明: IAbilityContinuation
    
    Saves the user data (carried in the IntentParams object) of a local ability generated during runtime. After the migration is triggered and the local ability is ready, this method is called when the Distributed Scheduler Service requests data from the local ability.
    
    指定者:
    
    onSaveData 在接口中 IAbilityContinuation
    
    参数:
    
    saveData - Indicates the user data to save.
    
    返回:
    
    Returns true if the data is successfully saved; returns false otherwise.
  - onRemoteTerminated
```
public void onRemoteTerminated()
```
    从接口复制的说明: IAbilityContinuation
    
    Called to notify the local device when a running ability on the remote device is destroyed after a reversible migration is performed for the ability from the local device to the remote device. A reversible migration is triggered by calling Ability#continueAbilityReversibly() or Ability#continueAbilityReversibly(String).

```
public boolean onKeyDown(int keyCode,
                         KeyEvent keyEvent)
```
    Called when a key is pressed. When any component in the Ability gains focus, the key-down event for the component will be handled first. This callback will not be invoked if the callback triggered for the key-down event of the component returns true. The default implementation of this callback does nothing and returns false.
    
    覆盖:

```
    从接口复制的说明: IAbilityContinuation

  - setInstanceName
```
public void setInstanceName(String name)
```
    Sets an instance name.
    The instance name must be the same as the module.js.name value in config.json.
    - If the value is MainAbility, call this method in the onStart method of the Ability instance to set the instance name to MainAbility.
    - If the default value is retained, you do not need to call this method to set the instance name for the Ability instance.
    Note that this method must be called before the super.onStart method.
    For an application with multiple instances, the module.js field contains more than one name items. You need to identify the item for the current instance.
    
    Example code:
```
 public class MainAbility extends AceAbility {
     @Override
     public void onStart(Intent intent) {
         setInstanceName("MainAbility");
         super.onStart(intent);

```
public void setPageParams(String url,
                          IntentParams params)
```
    Sets page parameters.
    You can use this method to set the home page URL and parameters. After the home page is successfully loaded, you can use this.xxx (xxx: a parameter key) to obtain the parameter values. Note that this method must be called before the super.onStart method.
    
    Example code:
```
 public class MainAbility extends AceAbility {
     @Override
     public void onStart(Intent intent) {
         IntentParams intentParams = new IntentParams();
         intentParams.setParam("key1", value1);

     }
 }
 
```
    参数:
    
    url - Indicates the page URL to set, which is an item in the pages clause of the config.json file.

public void pushPage(String url,
                     IntentParams params)
```
    Navigates to another page in the application based on the page URL and parameters.
    After the page is successfully loaded, you can use this.xxx (xxx: a parameter key) to obtain the parameter values. Do not call this method in the onStart method.
    
    Example code:
```
 public class MainAbility extends AceAbility {
     @Override
     public void onNewIntent(Intent intent) {
         IntentParams intentParams = new IntentParams();
