定义Uri Android时应用关闭

Question

当我执行此代码时，它可以在模拟器中正常运行（甚至保存图像），但会关闭手机上的应用程序（关系5）

当我在Uri行周围设置try catch时，程序不会崩溃（但是再次，其null值也可能对其下面的代码没有影响）

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode== 0 && resultCode == Activity.RESULT_OK) {
        Bitmap x = (Bitmap) data.getExtras().get("data");
        userImage.setImageBitmap(x);
        ContentValues values = new ContentValues();
        values.put(Images.Media.TITLE, "profileimage");
        values.put(Images.Media.BUCKET_ID, "profileimage");
        values.put(Images.Media.DESCRIPTION, "profile Image");
        values.put(Images.Media.MIME_TYPE, "image/jpeg");
        Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
        OutputStream outstream;
        try {
            outstream = getContentResolver().openOutputStream(uri);
            x.compress(Bitmap.CompressFormat.JPEG, 70, outstream);
            outstream.close();
        } catch (FileNotFoundException e) {
        } catch (IOException e) {
        }
    }
}

干杯!

编辑：（对不起，我的不活跃-记录：D的新Android手机）

这是错误日志：

您的Nexus 5正在运行哪个Android版本？ 如果是棉花糖（或N预览），则很可能是由代码的Media.EXTERNAL_CONTENT_URI部分引起的权限问题。
