This article describes the Android mobile phone access to root permissions and realize the shutdown and restart function, is a very common Android program design important function. I share it with you for your reference in the development of Android program.
The specific function code is as follows:
/*
* Execute the command
* @param command
* 1 , get root permissions "chmod 777 "+getPackageCodePath()
* 2 And turn it off reboot -p
* 3 , restart reboot
*/
public static boolean execCmd(String command) {
Process process = null;
DataOutputStream os = null;
try {
process = Runtime.getRuntime().exec("su");
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(command+"\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (Exception e) {
return false;
} finally {
try {
if (os != null) {
os.close();
}
if(process != null) {
process.destroy();
}
} catch (Exception e) {
e.printStackTrace();
}
}
return true;
}
It is hoped that the examples described in this article will be helpful to your Android programming.
