错误:ConnectionResult {statusCode = INTERNAL_ERROR,resolution = null}

Question

我正在开发我在我的应用程序中集成G​​oogle云端硬盘的应用程序.下面是我的代码,我只是从示例代码中复制,但在与Google云端硬盘连接时出现异常.

例外:ConnectionResult{statusCode=INTERNAL_ERROR, resolution=null}在onConnectionFailed()方法中.

请各位分享您的观点.

public class MainActivity extends Activity implements ConnectionCallbacks,
        OnConnectionFailedListener {

    private static final String TAG = "android-drive-quickstart";

    private static final int REQUEST_CODE_CREATOR = 2;
    private static final int REQUEST_CODE_RESOLUTION = 3;

    private GoogleApiClient mGoogleApiClient;
    private Bitmap mBitmapToSave;

    /**
     * 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.newContents(mGoogleApiClient).addResultCallback(new OnNewContentsCallback() {

            @Override
            public void onNewContents(ContentsResult 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;
                }

                Log.i(TAG, "New contents created.");
                // Get an output stream for the contents.
                OutputStream outputStream = result.getContents().getOutputStream();
                // Write the bitmap data from it.
                ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream();
                image.compress(Bitmap.CompressFormat.PNG, 100, bitmapStream);

当心!开发人员控制台中存在问题.

如果你在1)确保你已经用相应的证书指纹注册了包名,并且2)(重新)使用已经存在的项目之后你就会收到这个bug ,那么你应该检查这个项目是否有产品名称和一个与之关联的电子邮件地址(仔细检查一个),两者都可以在" 同意屏幕 "部分找到.

非常旧的项目可能没有填充这两个字段.较新的项目将这些字段填入一些默认值.

花了一天时间找到这个......

Answer 2

我按照以下步骤在API控制台上签署Google云端硬盘应用程序来解决此问题

1. 转到Google Developers Console.
2. 选择一个项目,或创建一个新项目.
3. 在左侧的侧栏中,展开API和auth.接下来,单击API.
4. 在API列表中,确保Drive API的状态为ON.
5. 在左侧的边栏中,选择凭据.

如果您的申请需要提交授权请求:

1. 在OAuth下,单击"创建新客户端ID".
2. 选择已安装的应用程序和Android.
3. 在包名称字段中,输入您的Android应用包名称.
4. 将SHA1指纹粘贴到请求的表单中.
5. 单击"创建客户端ID"

Answer 3

我通过注册应用程序并生成签名证书指纹解决了这个问题.

https://developers.google.com/drive/android/auth#generate_the_signing_certificate_fingerprint_and_register_your_application

我按照上面的链接,它解决了我的问题.
