}

var attachFile= new Array();

fileSystem.root.getDirectory("RepairMyCar", {
create: true
}, function(directory) {
console.log("Final 63" + directory.fullPath);
attachPaths = directory.fullPath;
var attachPath=attachPaths.slice(7,attachPaths.length);

}
}, function (error) {

});
});

console.log(message1);

答案 0 :(得分：2)
错误在行
中emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(body));
问题是HTML.fromHtml（body）返回一个android.text.SpannableStringBuilder，它不能被转换为java.util.ArrayList。 尝试用
替换那行代码emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(body).toString());
或
ArrayList<String> list = new ArrayList<String>();
list.add(Html.fromHtml(body).toString());
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, list);
答案 1 :(得分：0)
