Is there any one that can help me with a code to set a password to lock the screen ? thx
Use this code in your App, it works for me:
DevicePolicyManager devicePolicyManager =
DevicePolicyManager.getSystemService(Context.DEVICE_POLICY_SERVICE);
ComponentName demoDeviceAdmin = new ComponentName(this, name of activity);
devicePolicyManager.setPasswordQuality(
demoDeviceAdmin,DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED);
devicePolicyManager.setPasswordMinimumLength(demoDeviceAdmin, 5);
boolean result = devicePolicyManager.resetPassword("123456",
DevicePolicyManager.RESET_PASSWORD_REQUIRE_ENTRY);
Toast.makeText(this,
"button_lock_password_device..."+result,
Toast.LENGTH_LONG).show();
