github error

git push remote branch時出現

Github “Updates were rejected because the remote contains work that you do not have”

這是因為創建repo時選擇了建立readme

此時readme沒有和本機同步

所以必須先和remote同步

sol:

git remote add origin //your github url

//pull those changes

git pull origin master

//now, push your work to your new repo

git push origin master

git pull origin master時 

error: Your local changes to the following files would be overwritten by merge:

 index.rtf



必須先commit



git commit -m "index.rtf"



git pull origin master



git push origin master



大功告成！

google map要求MD5 SHA1

更新完google play servise 出現Android.r檔無法匯入

為了使用新的google map
必須裝新版的google service
裝完必須更新eclipse
最後要使用android tools ->add support library
解決

zxing

library 用zxing2.1版本
1匯入project "android"
2把core裡面的core.jar放到上1步驟專案的  新建一個libs資料夾下 就沒有錯誤了
3.右鍵點專案選porperty -> android ->islibrary鉤起來
4.到自已專案 porperty-> android ->add library
5.記得把activity加入自己專案
6.Intent intent = new Intent(getActivity(),
      CaptureActivity.class);
      // Intent intent = new
      // Intent("com.google.zxing.client.android.SCAN");
      intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
      startActivityForResult(intent, 0);

//接收訊息
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
  Log.d("tf", "resultCode = " + resultCode);
  if (requestCode == 0) {
   if (resultCode == 1) {
    // Handle successful scan
    String capturedQrValue = intent.getStringExtra("RESULT");
    //String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
  //   Toast.makeText(FragQRCodeScan.this,"Scan Result:" + capturedQrValue, Toast.LENGTH_SHORT).show();

   } else if (resultCode == 2) {
   // Handle cancel
   }
  } else {

  }
 }
