handleIntent

boolean handleIntent(android.content.Intent data,
                     IWXAPIEventHandler handler)

Call handleIntent(Intent, IWXAPIEventHandler) in BroadcastReceiver. For example

 class SampleEventProcessor extends BroadcastReceiver implements IWXAPIEventHandler {
 
        // override broadcast receiver
        public void onReceive(Context context, Intent data) {
                final IWXAPI api = WXAPIFactory.createWXAPI(context, null);
                if (api.handleIntent(data, this)) {
                        // intent handled as wechat request/response
                        return;
                }
 
                // process other intent as you like
        }
 
        // process request
        public void onReq(BaseReq req) {
 
                switch (req.getType()) {
                case ConstantsAPI.COMMAND_GETMESSAGE_FROM_WX:
                        Toast.makeText(context, "get message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SHOWMESSAGE_FROM_WX:
                        Toast.makeText(context, "show message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                default:
                        break;
                }
        }
 
        // process response
        public void onResp(BaseResp resp) {
                switch (resp.getType()) {
                case ConstantsAPI.COMMAND_SENDAUTH:
                        Toast.makeText(context, "get auth resp, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SENDMESSAGE_TO_WX:
                        // Process SendMessageToWX.Resp returned by WeChat
                        Toast.makeText(context, "send messsage to wx resp, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                default:
                        break;
                }
        }
 }

and DON'T FORGET to add SampleEventProcessor BroadcastReceiver in AndroidManifest.xml

在BroadcastReceiver中调用handleIntent(Intent, IWXAPIEventHandler)，例如：

 class SampleEventProcessor extends BroadcastReceiver implements IWXAPIEventHandler {
 
        // override broadcast receiver
        public void onReceive(Context context, Intent data) {
                final IWXAPI api = WXAPIFactory.createWXAPI(context, null);
                if (api.handleIntent(data, this)) {
                        // intent handled as wechat request/response
                        return;
                }
 
                // process other intent as you like
        }
 
        // process request
        public void onReq(BaseReq req) {
 
                switch (req.getType()) {
                case ConstantsAPI.COMMAND_GETMESSAGE_FROM_WX:
                        Toast.makeText(context, "get message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SHOWMESSAGE_FROM_WX:
                        Toast.makeText(context, "show message from wx, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                default:
                        break;
                }
        }
 
        // process response
        public void onResp(BaseResp resp) {
                switch (resp.getType()) {
                case ConstantsAPI.COMMAND_SENDAUTH:
                        Toast.makeText(context, "get auth resp, processed here", Toast.LENGTH_LONG).show();
                        break;
 
                case ConstantsAPI.COMMAND_SENDMESSAGE_TO_WX:
                        // 处理微信主程序返回的SendMessageToWX.Resp
                        break;
 
                default:
                        break;
                }
        }
 }

别忘了在AndroidManifest.xml中增加SampleEventProcessor这个BroadcastReceiver：

或者在代码中注册这个事件：

Parameters:: data -; handler -
Returns:: true if handled

isWXAppInstalled
```
boolean isWXAppInstalled()
```
check wechat app installation status

Returns:

true if installed

```
int getWXAppSupportAPI()
```
get api level from installed wechat app

Returns:

api level

openWXApp
```
boolean openWXApp()
```
launch wechat app

Returns:

true if launched

sendReq
```
boolean sendReq(BaseReq req)
```
send request to wechat app

Parameters:

req -

Returns:

true if sent

sendResp
```
boolean sendResp(BaseResp resp)
```
send response to wechat app, make sure that the response have same transaction with request

Parameters:

resp -

Returns:

true if sent

detach
```
void detach()
```

setLogImpl
```
void setLogImpl(ILog log)
```
