I’m performing the following code to execute linux commands in my android application that I’m creating:
public void RunAsRoot(String[] cmds){
Process p = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(p.getOutputStream());
for (String tmpCmd : cmds) {
os.writeBytes(tmpCmd+"n");
}
os.writeBytes("exitn");
os.flush();
}
I want to know if there is a way to know what the command is returning after it is executing. for example, if I do “ls” I would like to see what the command wold normally output.
Answer
try this code :
try {
Process process = Runtime.getRuntime().exec("ls");
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));
StringBuilder result=new StringBuilder();
String line = "";
while ((line = bufferedReader.readLine()) != null) {
result.append(line);
}
TextView tv = (TextView)findViewById(R.id.textView1);
tv.setText(result.toString());
}
catch (IOException e) {}
