打开少数设备的csv文件时应用崩溃...所有运行相同android版本的设备

File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+File.separator +filename+".csv");
        Intent target = new Intent(Intent.ACTION_VIEW);
        target.setDataAndType(Uri.fromFile(file),"text/csv");
        target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        Intent icsv = Intent.createChooser(target, "Open File");
        try {
            startActivity(icsv);
        } catch (ActivityNotFoundException e) {
            // Instruct the user to install a PDF reader here, or something
            Toast.makeText(this, "get a csv reader", Toast.LENGTH_SHORT).show();
        }

每当您尝试从应用程序内部打开文件时，最佳做法是将打开的意图代码包含在构建版本检查中。请参考下面的示例，并根据您的要求对其进行编辑，这肯定会解决该问题。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                Uri apkUri = FileProvider.getUriForFile(mContext, BuildConfig.APPLICATION_ID + ".provider", toInstall);
                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setData(apkUri);
                intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                mContext.startActivity(intent);
            } else {
                Uri apkUri = Uri.fromFile(toInstall);
                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setDataAndType(apkUri, "*/*");
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                mContext.startActivity(intent);
            }
