点击此按钮
时出现错误twitterbutton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
loginToTwitter();
String token = "" + accessToken;
//Toast.makeText(getApplicationContext(), token, 500).show();
}
});
当我点击这个按钮时它强制关闭这是日志猫

请注意，此代码适用于没有facebook的其他项目 所有需要的权限都已添加
问题是，当我点击推特按钮时，它会强行关闭
答案 0 :(得分：0)
我有同样的问题..几天后我发现了问题：
// We cannot define our own keys for Javascript arrays, so we are using Object
var result = new Object();
var salesIndex = 8;
var idIndex = 0;
var ndiIndex = 7;
for(var i=0; i< array1.length; i++){
// array containing all line's columns
var columns = array1[i].split(",");
// especific columns that is of our interest
var rowSale = columns[salesIndex];
var rowId = columns[idIndex];
var rowNdi = columns[ndiIndex];
// If sale key doesn't exists in the array, add it
if (!(rowSale in columns)) {
result.rowSale.rowId = new Array();
result.rowSale.rowId.push(rowNdi);
} else if (!(rowId in columns.rowSale)) {
// If id key doesn't exists in the array, add it
result.rowSale.rowId = new Array();
result.rowSale.rowId.push(rowNdi);
} else if (!columns.rowSale.rowId.indexOf(rowNdi)) {
// If ndi isn't in the array, add it
result.rowSale.rowId.push(rowNdi);
}
}
noHistory =“true”导致twitter登录后关闭力
