In my android application, I want to restart my android device on button click.
But its not working.
I have done this so far.
ImageButton restartmob = (ImageButton) this.findViewById(R.id.restartmob);
restartmob.setOnClickListener(new ImageButton.OnClickListener() {
@Override
public void onClick(View v) {
Process proc = null;
try {
//proc = Runtime.getRuntime().exec(new String[] { "su", "-c", "reboot" });
proc = Runtime.getRuntime().exec(new String[]{"/system/bin/su","-c","reboot now"});
proc.waitFor();
} catch (Exception ex) {
Log.i(TAG, "Could not reboot", ex);
}
}
});
Also I put the following permission in the manifest file.
<permission android:name="android.permission.REBOOT"/>
When I clicked the image button to restart, I got the following exception.
java.io.IOException: Error running exec(). Command: [/system/bin/su, -c, reboot now]

What's wrong with my code? Please help me on this.
For the info, I am testing on android Lollipop (if it matters).
Thanks in Advance.
