IO EXCEPTION导入Android中的本地.vcf文件

Question

我正在开发需要导入本地.vcf文件的Android 2.3.3上的应用程序。 我尝试导入它启动意图

final String pathDownload = Environment.getExternalStorageDirectory()+"/vcard1.vcf";

    Intent i = new Intent();
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    i.setAction(android.content.Intent.ACTION_VIEW);
    i.setDataAndType(Uri.parse(pathDownload), "text/x-vcard");
    activity.startActivity(i);

但这会导致IOException，即使该文件存在并且可以轻松地从任何文件管理器导入该文件。 有任何想法吗？

更新：更改意向：

     Intent i = new Intent(android.content.Intent.ACTION_VIEW,   Uri.parse(pathDownload));
     i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
     i.setType("text/x-vcard");
     activity.startActivity(i);

我可以导入任何2.1 vcf文件。 但是，如果我使用3.0 vcf尝试相同的操作，将会发生以下情况：

清单权限：

<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>

Answer 1

java.io.FileNotFoundException: No content provider: /storage/sdcard0/vcard1.vcf

它清楚地表明文件不可用

并且您是否已在清单文件中授予权限 ？

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