我正在制作 android 应用程序,它将简单地从 sdcard(电话库)中选择一个图像并将其存储到 Google 驱动器。我在这方面做了很多努力,我从 Google 开发人员在drive quick start上提供的代码中获得了帮助。我在我的 main.xml 文件中创建了一个 Button 控件,当单击此按钮时,它会进入手机图库,当我选择图片时,什么也没有发生

这是我的 Eclipse IDE 中的 Log Cat

最后,我找到了我的解决方案,现在我可以将图像从相机发送到 Google Drive(可在Drive Quick Start上找到),第二部分我已经从图库中选择了一张图片并将其存储到 Google Drive。请参阅下面的代码

@Override
    protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) 
    {
        switch (requestCode) 
        {
        case REQUEST_ACCOUNT_PICKER:
            if (resultCode == RESULT_OK && data != null && data.getExtras() != null) 
            {

                if (accountName != null) 
                {
                    credential.setSelectedAccountName(accountName);
                    service = getDriveService(credential);
                }
            }
            break;

        case REQUEST_AUTHORIZATION:

            {
