驱动器的SDK为Android AuthIntent为null [英] Drive SDK for Android AuthIntent is null
本文介绍了驱动器的SDK为Android AuthIntent为null的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想谷歌驱动器集成到我的Android应用程序，这样我可以在用户的硬盘存储文件。我已经在App控制台启用两个驱动SDK和API驱动器，并设置了我的Oauth 2的ClientID我的SHA1指纹。至于我可以告诉大家，一切看起来都对谷歌的到底好不好。
这里的code，它初始化我Drive对象。
私人布尔initializeService（字符串帐户名）{
如果（服务！= NULL）{
返回true;
}
GoogleAccountCredential凭证= GoogleAccountCredential.usingOAuth2（mContext，DriveScopes.DRIVE）;
mAuthIntent = NULL; 如果（帐户名！= NULL）{
尝试{
credential.setSelectedAccountName（帐户名）;
Log.d（DriveHelper，credential.getToken（））;
服务= getDriveService（凭证）;
}赶上（例外前）{
如果（前的instanceof UserRecoverableAuthException）{
UserRecoverableAuthException authException =（UserRecoverableAuthException）前;
mAuthIntent = authException.getIntent（）;
mError code = CloudHelper.CONNECTION_AUTHENTICATE;
（（活动）mContext）.startActivityForResult（mAuthIntent，REQUEST_AUTHORIZATION）;
}其他{
Log.e（DriveCloudHelper，错误检索身份验证令牌，前）;
} 返回false;
}
getAppFolder（）; 返回mFileLocation！= NULL;
} 活动活动=（活动）mContext;
activity.startActivityForResult（credential.newChooseAccountIntent（），REQUEST_ACCOUNT_PICKER）;
返回false;
}私人驱动器getDriveService（GoogleAccountCredential凭证）{
返回新Drive.Builder（AndroidHttp.newCompatibleTransport（），新GsonFactory（），凭据）
.setApplicationName（驱动器助手）
。建立（）;
}
这些方法称为在后台线程和工作得很好，在帐户选择器出现时，授权窗口，都好。我的 getAppFolder 方法查找特定的文件夹，并创建它，如果没有present没有任何问题（在同一个后台线程）。
然而，当我去上传文件到驱动器，第一个操作我尝试一个新的后台线程导致 UserRecoverableAuthException ，但是当我打电话发生新的异常 getIntent ，因为没有意图提供，并且详细消息是 AppDownloadRequired 。
下面是一个的产生异常的方法。
私人字符串getIdFromFolder（字符串位置，字符串名称，布尔创建）{
尝试{
串maskedName = name.replaceAll（/，）;
查询字符串=标题包含+ maskedName +和+位置+父母;
。文件清单列表= service.files（）名单（）setMaxResults（1）.setQ（查询）.execute（）;
清单＆LT;文件＆gt;文件= list.getItems（）; 如果（files.isEmpty（））{
返回创建？ createSubFolder（位置，名称）：空;
} 返回files.get（0）.getId（）;
}赶上（IOException异常五）{
//在这里吃的例外
Log.w（DriveCloudHelper，E）;
}
返回创建？ createSubFolder（位置，名称）：空;
}
和这里的堆栈跟踪：

解决方案
尝试使用 mContext.getApplicationContext（）在 GoogleAccountCredential.usingOAuth2 通话，而不是 mContext 作为，似乎有固定的类似的问题在其他地方的。
I'm trying to integrate Google Drive into my Android app so that I can store files in a user's Drive. I've enabled both Drive SDK and Drive API in the App Console and set up my Oauth 2 ClientIDs with my SHA1 fingerprint. As far as I can tell, everything looks good on Google's end.
Here's the code that initializes my Drive object.
private boolean initializeService(String accountName) {
if(service != null) {
return true;
}
GoogleAccountCredential credential = GoogleAccountCredential.usingOAuth2(mContext, DriveScopes.DRIVE);
mAuthIntent = null;
if(accountName != null) {
try {
credential.setSelectedAccountName(accountName);
Log.d("DriveHelper", credential.getToken());
service = getDriveService(credential);
} catch(Exception ex) {
if(ex instanceof UserRecoverableAuthException) {
UserRecoverableAuthException authException = (UserRecoverableAuthException)ex;
mAuthIntent = authException.getIntent();
mErrorCode = CloudHelper.CONNECTION_AUTHENTICATE;
((Activity)mContext).startActivityForResult(mAuthIntent, REQUEST_AUTHORIZATION);
} else {
Log.e("DriveCloudHelper", "Error retrieving auth token", ex);
}
return false;
}
getAppFolder();
return mFileLocation != null;
}
Activity activity = (Activity)mContext;
activity.startActivityForResult(credential.newChooseAccountIntent(), REQUEST_ACCOUNT_PICKER);
return false;
}
private Drive getDriveService(GoogleAccountCredential credential) {
return new Drive.Builder(AndroidHttp.newCompatibleTransport(), new GsonFactory(), credential)
.setApplicationName("Drive Helper")
.build();
}
These methods are called on a background thread and work just fine, the Account Picker appears, the Authorization window appears, all good. My getAppFolder method looks for a specific folder and creates it if not present without any issue (on the same background thread).
However, when I go to upload a file to Drive, the first operation I try on a new background thread causes a UserRecoverableAuthException, but a new exception occurs when I call getIntent because there's no Intent provided, and the detail message is AppDownloadRequired.
Here's the method that's generating the exception.
private String getIdFromFolder(String location, String name, boolean create) {
try {
String maskedName = name.replaceAll("/", "");
String query = "title contains '" + maskedName + "' and '" + location + "' in parents";
FileList list = service.files().list().setMaxResults(1).setQ(query).execute();
List<File> files = list.getItems();
if (files.isEmpty()) {
return create ? createSubFolder(location, name) : null;
}
return files.get(0).getId();
} catch (IOException e) {
// Eat the exception here
Log.w("DriveCloudHelper", e);
}
return create ? createSubFolder(location, name) : null;
}
And here's the stacktrace:

解决方案
Try using mContext.getApplicationContext() in your GoogleAccountCredential.usingOAuth2 call rather than mContext as that seems to have fixed similar issues elsewhere.
