我正在尝试共享文本文件。我已经按照所有必需的步骤使用FileProvider为> = Nougat共享文件,但仍然收到FileUriExposedException:

我的共享代码为:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N || Config.ONLY_INTERNAL_STORAGE) {
try {
String packageId = context.getPackageName();
return FileProvider.getUriForFile(context, packageId + FILE_PROVIDER, file);
} catch(IllegalArgumentException e) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
throw new SecurityException();
} else {
return Uri.fromFile(file);
}
}
} else {
return Uri.fromFile(file);
}
,并且还为意图添加了权限:
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
如果有人可以帮助我解决此问题。谢谢。
编辑: 我的意图代码如下:
intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_SUBJECT, "abc");
try {
intent.putExtra(Intent.EXTRA_STREAM, FileBackend.getUriForFile(activity, chatFile));
} catch (SecurityException e) {
Toast.makeText(activity, activity.getString(R.string.no_permission_to_access_x, chatFile.getAbsolutePath()), Toast.LENGTH_SHORT).show();
return null;
}
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
答案 0 :(得分:1)
您不需要此检查(Build.VERSION.SDK_INT> = Build.VERSION_CODES.N)。
目标版本需要为API 24或更高版本,而不是内部版本或android版本。 由于正在生成的uri仍然是file://,因此您将收到此异常。
