android - Copying from /data/app folder using superuser

Question

I am trying to copy files from /data/app folder, but facing the following issues, please advice.

Process suProcess = Runtime.getRuntime().exec("su");
DataOutputStream os = new     DataOutputStream(suProcess.getOutputStream);

1. Error is, Required : android.os.Process, Found : java.lang.Process in the first line of the code.
2. Cannot resolve symbol, getOutputStream in the second line.

Kindly let me know why these issues occur, and how do I resolve them. Thanks.

Answer 1

android.os.Process，找到：java.lang.Process

确保导入正确的类。

import java.lang.Process;

或者像这样声明你的过程：

java.lang.Process suProcess = Runtime.getRuntime().exec("su"); 

无法解析符号，getOutputStream

getOutputStream是一种方法，那么您需要添加()才能编译您的代码。

DataOutputStream os = new     DataOutputStream(suProcess.getOutputStream());
