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);

一切都好。但是一些选择者撞毁了我的应用程序。有了这个，我收到以下错误：

任何想法，谢谢你的帮助？

特别是在 Kitkat 中，您将获得权限拒绝例外，为了解决此问题，您可以执行此操作添加此权限

<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);
}

启动Intent时权限被拒绝。使用ACTION_GET_CONTENT设置类型（＆＃34; * / *＆＃34;）
