【问题描述】：
我正在尝试将我的应用连接到 Google Play 服务以访问 Google 云端硬盘，但它显示 连接失败 状态代码为 SIGN_IN_REQUIRED.
但它的行为似乎就在 3 天前。我还检查了谷歌的开发者控制台。他们可能在 API 中更改了一些我无法弄清楚的内容。欢迎您的帮助。
我的代码：
/**
* Create a new file and save it to Drive.
*/
private void saveFileToDrive(final byte[] data) {
// 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<DriveApi.DriveContentsResult>() {
@Override
public void onResult(DriveApi.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());
outputStream.write(data);
} 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("application/pdf").setTitle(filename).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 (IntentSender.SendIntentException e) {
Log.i(TAG, "Failed to launch file chooser.");
}
}
});
}
@Override
protected void onResume() {
super.onResume();
if (mGoogleApiClient == null) {
// Create the API client and bind it to an instance variable.
// We use this instance as the callback for connection and connection
// failures.
// Since no account name is passed, the user is prompted to choose.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Drive.API)
.addScope(Drive.SCOPE_FILE)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
}
// Connect the client. Once connected, the camera is launched.
mGoogleApiClient.connect();
}
@Override
protected void onPause() {
if (mGoogleApiClient != null) {
mGoogleApiClient.disconnect();
}
super.onPause();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case REQUEST_CODE_CREATOR:
// Called after a file is saved to Drive.
if (resultCode == RESULT_OK) {
Log.i(TAG, "Image successfully saved.");
Intent intent = new Intent();
intent.putExtra("FILE_PATH",file_path);
PreviewActivity.this.setResult(RESULT_OK, intent);
finish();
progressDialog.hide();
}
break;
}
}
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "API client connected.");
//saveFileToDrive();
}
@Override
public void onConnectionSuspended(int i) {
Log.i(TAG, "GoogleApiClient connection suspended");
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
// Called whenever the API client fails to connect.
Log.i(TAG, "GoogleApiClient connection failed: " + connectionResult.toString());
if (!connectionResult.hasResolution()) {
// show the localized error dialog.
GoogleApiAvailability.getInstance().getErrorDialog(this, connectionResult.getErrorCode(), 0).show();
return;
}
// The failure has a resolution. Resolve it.
// Called typically when the app is not yet authorized, and an
// authorization
// dialog is displayed to the user.
try {
connectionResult.startResolutionForResult(this, REQUEST_CODE_RESOLUTION);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG, "Exception while starting resolution activity", e);
}
}
