is this possible to do programmatically in android?

I found this threads: Android: How to turn screen on and off programmatically?

Turning screen on and off programmatically not working on some devices

but there is no timer after 1 minute.

Answer 1

Yes, the method best used in this case is to programmatically set screen timeout instead.

Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, 1000);

1000 is in milliseconds which means 1 second, you can replace it with any value as desired.

Needed permission:

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

UPDATE

It will overwrite the phone system value (Settings/Display/Sleep), so perhaps you need to restore the current settings after finish:

private static final int SCREEN_OFF_TIME_OUT = 13000;
private int mSystemScreenOffTimeOut;
private void setScreenOffTimeOut() {
    try {
        mSystemScreenOffTimeOut = Settings.System.getInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT);
        Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, SCREEN_OFF_TIME_OUT);
    } catch (Exception e) {
        Utils.handleException(e);
    }
}

private void restoreScreenOffTimeOut() {
    if (mSystemScreenOffTimeOut == 0) return;
    try {
        Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, mSystemScreenOffTimeOut);
    } catch (Exception e) {
        Utils.handleException(e);
    }
}
