android - 错误 : ConnectionResult{statusCode=INTERNAL_ERROR, 分辨率 = null}

Question

我正在开发将 Google Drive 集成到我的应用程序中的应用程序。以下是我的代码，我只是从示例代码中复制而来，但在连接 Google Drive 时出现异常。

异常:onConnectionFailed() 方法中的 ConnectionResult{statusCode=INTERNAL_ERROR, resolution=null}。

请大家分享你的观点。

public class MainActivity extends Activity implements ConnectionCallbacks,
        OnConnectionFailedListener {

    private static final String TAG = "android-drive-quickstart";
    private static final int REQUEST_CODE_CAPTURE_IMAGE = 1;
    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;
                }
                // 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.getContents().getOutputStream();
                // Write the bitmap data from it.
                ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream();
                image.compress(Bitmap.CompressFormat.PNG, 100, bitmapStream);
                try {
                    outputStream.write(bitmapStream.toByteArray());

请注意!开发者控制台出现问题。

如果您在 1) 确保您已使用其对应的 证书指纹 注册 包名称，并且 2) 正在(重新)使用之后仍遇到此错误一个已经存在的项目，那么你应该检查这个项目有一个产品名称和一个电子邮件地址(双检查与它相关的一个特别)，两者都可以在“同意屏幕”部分中找到。

非常古老的项目可能没有填充这两个字段。较新的项目在这些字段中填写了一些默认值。

我花了一天时间才找到这个......
