public static boolean runRootCommand(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) {
Log.d("*** DEBUG ***", "Unexpected error - Here is what I know: "+e.getMessage());
return false;
}
finally {
try {
if (os != null) {
os.close();
}
process.destroy();
} catch (Exception e) {
// nothing
}
}
return true;
}
}
