[英]How to execute shell commands through su?
I tried following way but its not working for me : 我尝试了以下方法,但对我不起作用:
public void RunAsRoot(String cmnd){
Process p = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(p.getOutputStream());
os.writeBytes(cmnd +"\n");
os.writeBytes("exit\n");
os.flush();
p.waitFor();
}
I tried this as well : 我也尝试过这个:
public void RunAsRoot(String cmds){
Process p = Runtime.getRuntime().exec("su -c " + cmds);
p.waitFor();
}
But none of the above method is working. 但是上述方法均无效。 However following command is working for me in shell through adb :
但是以下命令通过adb在shell中为我工作:
su -c "input" " keyevent" " 3"
So I even tried this : 所以我什至尝试了这个:
public void RunAsRoot(String cmds){
Process p = Runtime.getRuntime().exec("su -c \"input\" \" keyevent\" \" 3\"");
p.waitFor();
}
But even this didn't work. 但是,即使这样也不起作用。 Can anyone please help me!!!!
谁能帮帮我吗!!!!
I use an OutputStream
instead of a DataOutputStream
我使用
OutputStream
而不是DataOutputStream
sh = Runtime.getRuntime().exec("su", null,null);
String now = c.get(Calendar.YEAR) + "-" + c.get(Calendar.MONTH) + "-" + c.get(Calendar.DAY_OF_MONTH) + "-" + c.get(Calendar.HOUR)+":"+c.get(Calendar.MINUTE);
Log.d(TAG, "Creating screenshot " + now +".png");
OutputStream os = sh.getOutputStream();
os.write(("/system/bin/screencap -p " + "/data/local/" + now +".png").getBytes("ASCII"));
os.flush();
os.close();
sh.waitFor();
