android7.0之后用系统图片查看器打开应用目录的图片

Intent intent = new Intent(Intent.ACTION_VIEW);

filePath = "这里是图片文件路径";Uri uri;if (Build.VERSION.SDK_INT >= 24) {    File file = new File(filePath);    Log.i("mine",file.length()+"");    uri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", new File(filePath));    intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);//注意加上这句话} else {    uri = Uri.fromFile(new File(filePath));}intent.setDataAndType(uri, "image/*");startActivity(intent);
