[android-developers] how to change sequre settings from my app

Good morning 

I'm trying to change some settings on system using a root device. I'm trying to change the speech rate of the TTS.

I use this code to do that:

int _value = 100; // sample value

Settings.Secure.putInt(this.getContentResolver(), Settings.Secure.TTS_DEFAULT_RATE, _value);

Settings.Secure.putInt(this.getContentResolver(), Settings.Secure.ACCESSIBILITY_ENABLED, 0);

Settings.Secure.putInt(this.getContentResolver(), Settings.Secure.ACCESSIBILITY_ENABLED, 1);

the problem is the application need these permissions in the manifest file:

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

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

I am using a rooted device but the application is still not working.

Please, could you give me any suggestions?

thanks in advance
