我正在尝试使用Fusiontables.Table.ImportRows将csv文件导入到我的fusion-table中。但是当我运行execute()时,我得到一个没有附加信息的NullPointerException。
我正在使用FusionOAuth2示例代码并实现了另一种方法:
private static void importRows(final String tableId){
try {
final String text = "Text,Number,Location\n" +
"company,13,my street 14";
final ByteArrayContent byteArrayContent = ByteArrayContent.fromString("text/comma-separated-values", text);
final Fusiontables.Table.ImportRows importRows = fusiontables.table().importRows(tableId, byteArrayContent);
importRows.setEncoding("UTF-8");
importRows.execute();
} catch (IOException e) {
e.printStackTrace();
} catch (NullPointerException e) {
e.printStackTrace();
}
}
这是例外:
java.lang.NullPointerException

我错过了什么?
答案 0 :(得分:0)
您是否更改了初始化fusiontables对象的方式(com.google.api.services.fusiontables.Fusiontables)?
