在Google-Chrome-ARC上本地文件访问? [英] local file access on Google-Chrome-ARC?

问题描述

有什么方法可以在ARC上实现本地文件访问吗?据我了解，Chrome是沙盒存储，因此访问将很困难，但是似乎已定义的android数据目录可能具有用于文件访问的特定文件夹?

Is there any way to implement local file access on ARC? As i understand Chrome is sandboxed, so access would be hard, but it seems that the defined android data directory could have a specific folder used for file access?

推荐答案

是的，ARC上的应用程序已沙盒化，无法访问本地文件系统.

Yes, application on ARC is sandboxed and unable to access to local file system.

但是，您可以通过以下特定意图启动Activity来访问本地文件系统上的文件:ACTION_GET_CONTENT用于读取文件，而ACTION_SEND用于保存文件.

However, you can access to the file on your local file system by starting Activity with specific Intent: ACTION_GET_CONTENT for reading file and ACTION_SEND for saving file.

例如如果您要从本地文件系统打开图像文件，

e.g. If you would like to open image file from your local file system,

private static int REQUEST_CODE = 5;

private void requestImageFile() {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    startActivityForResult(intent, REQUEST_CODE);
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK && requestCode == REQUEST_CODE) {
        ImageView imgView = new ImageView(this);
        imgView.setImageURI(data.getData());
        setContentView(imgView);
    }
}
