使用驅動器api將sql數據庫上傳到谷歌驅動器

Question

我想在我的android應用程序中將數據庫文件上傳到Google驅動器。

我可以備份數據庫文件罰款保存到/ SD卡/ schoolbinder /備份/注意到

我用這個網站作爲開始：https://github.com/googledrive/android-quickstart/blob/master/app/src/main/java/com/google/android/gms/drive/sample/quickstart/MainActivity.java

這種工作方式是我的應用程序，但它圖片不是文件。關於如何上傳文件的任何想法

Answer 1

您引用的演示已經有選擇文件的示例。

/** 
* Create a new file and save it to Drive. 
*/ 
private void saveFileToDrive() { 
    // Start by creating a new contents, and setting a callback. 
    Log.i(TAG, "Creating new contents."); 
    final Bitmap image = mBitmapToSave; 
    Drive.DriveApi.newDriveContents(mGoogleApiClient) 
      .setResultCallback(new ResultCallback<DriveContentsResult>() { 

     @Override 
     public void onResult(DriveContentsResult result) { 
      // If the operation was not successful, we cannot do anything 
      // and must 
      // fail. 
      if (!result.getStatus().isSuccess()) { 
       Log.i(TAG, "Failed to create new contents."); 
       return; 
      } 
      // Otherwise, we can write our data to the new contents. 
      Log.i(TAG, "New contents created."); 
      // Get an output stream for the contents. 
      OutputStream outputStream = result.getDriveContents().getOutputStream(); 
      // Write the bitmap data from it. 
      ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream(); 
      image.compress(Bitmap.CompressFormat.PNG, 100, bitmapStream); 
      try { 
       outputStream.write(bitmapStream.toByteArray()); 
      } catch (IOException e1) { 
       Log.i(TAG, "Unable to write file contents."); 
      } 
      // Create the initial metadata - MIME type and title. 
      // Note that the user will be able to change the title later. 
      MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder() 
        .setMimeType("image/jpeg").setTitle("Android Photo.png").build(); 
      // Create an intent for the file chooser, and start it. 
      IntentSender intentSender = Drive.DriveApi 
        .newCreateFileActivityBuilder() 
        .setInitialMetadata(metadataChangeSet) 
        .setInitialDriveContents(result.getDriveContents()) 
        .build(mGoogleApiClient); 
      try { 
       startIntentSenderForResult(
         intentSender, REQUEST_CODE_CREATOR, null, 0, 0, 0); 
      } catch (SendIntentException e) { 
       Log.i(TAG, "Failed to launch file chooser."); 
      } 
     } 
    }); 
} 

它只是一個叫它的問題。看來演示正在調用相機應用程序並返回Image。嘗試刪除onConnected方法中的if條件，應該調用saveFileToDrive並顯示文件選取器。
