Eclipse（模拟器Android tablet）文件未找到，即使文件存在

Question

我在看文件。我不介意位置，所以我尝试了各种位置和方法来做到这一点：

File file = new File("DFirstPdf.pdf");
File file = new File("C:/DFirstPdf.pdf");
File file = new File("C:\\DFirstPdf.pdf");

PackageManager pm = getPackageManager();

List<ResolveInfo> activities = pm.queryIntentActivities(intent, 0);

if (activities.size() > 0) 
{
startActivity(intent);
}
else
{
// Do something else here. Maybe pop up a Dialog or Toast
}

Answer 1

您必须使用classloader来获取资源

getClassLoader（）.getResource（“dfirstpdf.pdf”）；
