Step 1 申請微信應用

進入:https://open.weixin.qq.com/ 交300軟妹幣,等通過。

填寫幾個重要資訊

1.應用簽名

2.包名

3.應用名字,重要事情說三遍,由於測試的心裡,應用名沒管它.其它都對,一直報ignore wechat app signature validation,吐血了,最後還好發現了,

不一樣試試改成申請的應用名字.終於好了.

Step 2配製檔案與lib

2.1.配製com.test是你APP包名

 <activity
            android:name="com.test.wxapi.WXEntryActivity"
            android:configChanges="keyboardHidden|orientation|screenSize"
            android:exported="true"
            android:label="@string/app_name"
            android:launchMode="singleTop"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />

                <data android:scheme="sdksample" />
            </intent-filter>
        </activity>
 

2.2匯入libammsdk包

Step 3呼叫的程式碼

3.1發起請求的程式碼

if(api==null){
    api=WXAPIFactory.createWXAPI(WelcomeActivity.this, APP_ID, false);  
    api.registerApp(APP_ID);
}
if (!api.isWXAppInstalled()) {
    //提醒使用者沒有按照微信
	Toast.makeText(WelcomeActivity.this, "沒有安裝微信,請先安裝微信!", Toast.LENGTH_SHORT).show();
    return;
}

SendAuth.Req req = new SendAuth.Req();
req.scope = "snsapi_userinfo";
req.state = "wechat_sdk_demo_test";
api.sendReq(req);
 

public class WXEntryActivity extends Activity implements IWXAPIEventHandler{  
	  
    private IWXAPI api;  
    
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        // TODO Auto-generated method stub  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.flash_activity);  

        if(api==null){
        	//wx30a9402cd2a87cf3
        	   api=WXAPIFactory.createWXAPI(this, APP_ID, false);  
               api.registerApp(APP_ID);
        }

        api.handleIntent(getIntent(), this); 
        handleIntent(getIntent());
    }  
      
 // 微信傳送請求到第三方應用時，會回撥到該方法
 	@Override
 	public void onReq(BaseReq req) {
 		switch (req.getType()) {
 		case ConstantsAPI.COMMAND_GETMESSAGE_FROM_WX:
// 			goToGetMsg();		
 			break;
 		case ConstantsAPI.COMMAND_SHOWMESSAGE_FROM_WX:
// 			goToShowMsg((ShowMessageFromWX.Req) req);
 			break;
 		default:
 			break;
 		}
 	}

 	// 第三方應用傳送到微信的請求處理後的響應結果，會回撥到該方法
 	@Override
 	public void onResp(BaseResp resp) {
// 		int result = 0;
 		String result="";
 		
 		switch (resp.errCode) {
 		case BaseResp.ErrCode.ERR_OK:
 			result = "errcode_success";
 			break;
 		case BaseResp.ErrCode.ERR_USER_CANCEL:
 			result = "errcode_cancel";
 			break;
 		case BaseResp.ErrCode.ERR_AUTH_DENIED:
 			result = "errcode_deny";
 			break;
 		default:
 			result = "errcode_unknown";
 			break;
 		}
 		
 		Toast.makeText(this, result, Toast.LENGTH_LONG).show();
 	}

    

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        handleIntent(intent);
    }

    private void handleIntent(Intent intent) {
        SendAuth.Resp resp = new SendAuth.Resp(intent.getExtras());
        if (resp.errCode == BaseResp.ErrCode.ERR_OK) {
            //使用者同意
        }
    }
}
