android - 启动 Intent 时拒绝权限。将 ACTION_GET_CONTENT 与设置类型 ("*/*"一起使用)

Question

使用 Aciton_Get_Content。我正在尝试获取链接文件、照片、视频 .... 以供上传。这是我的代码:

Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select file to upload "),88);

一切正常。但是一些选择器使我的应用程序崩溃了。有了这个，我收到以下错误:

有什么想法吗，谢谢你的帮助？

特别是在 Kitkat 中你会得到 Permission Denial exception，为了解决这个问题你可以添加这个权限

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

然后

Intent intent;
if (Build.VERSION.SDK_INT < 19) {
    intent = new Intent();
    intent.setAction(Intent.ACTION_GET_CONTENT);
    intent.setType("*/*");
    startActivityForResult(Intent.createChooser(intent, "Select file to upload "),88);
} else {
    intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("*/*");
    startActivityForResult(Intent.createChooser(intent, "Select file to upload "),88);
}
