我想在android上获取与gmail帐户相关的个人资料图片.我已经使用帐户选择器意图在我的应用程序中选择/登录gmail(身份验证).我使用了以下代码
mCredential = GoogleAccountCredential.usingOAuth2(
getApplicationContext(), Arrays.asList(SCOPES))
.setBackOff(new ExponentialBackOff())
.setSelectedAccountName(settings.getString("PREF_ACCOUNT_NAME", null));
在启动oAuth后,我最终得到以下结果方法
protected void onActivityResult(
int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode) {
case REQUEST_ACCOUNT_PICKER:
if (resultCode == RESULT_OK && data != null &&
data.getExtras() != null) {
String accountName =
data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
Log.e("ghfyg",""+accountName);
if (accountName != null) {
mCredential.setSelectedAccountName(accountName);
SharedPreferences settings =
AccountSync.this.getSharedPreferences("deep",Context.MODE_PRIVATE);
SharedPreferences.Editor editor = settings.edit();
editor.putString("PREF_ACCOUNT_NAME", accountName);
editor.apply();
}
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this,"Account unspecified.",Toast.LENGTH_SHORT).show();
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
} …我想将待处理数据上传到服务器,然后在同一按钮点击下载服务器数据库中的所有数据.但是我没有得到如何显示进度条显示上传/下载的进度.我尝试使用"setDownloadTaskDidWriteDataBlock"但它永远不会被调用.我的代码:
-(void)asyncTask:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *response))success failure:(void (^)(NSError *error))failure {
NSLog(@"parameters passed to server through services=%@",dictParams);
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
// [manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
[manager POST:strURL parameters:dictParams progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"inside requestPostUrl JSON: %@", responseObject);
if([responseObject isKindOfClass:[NSDictionary class]]) {
if(success) {
success(responseObject);
}
}
else {
NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject …
