[Q] Wifi disabler program - Android Software Development

I am trying to make a program that stops WiFi when the screen is locked and turns it on again when the screen is unlocked
this is what i have so far:
Code:
public class NoScreenNoWifi extends Activity {
TextView tvEnabler;
TextView tvExplanation;
TextView tvStatus;
CheckBox cbEnabler;
WifiManager wifi;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tvEnabler = (TextView) findViewById(R.id.tvEnabler);
tvExplanation = (TextView) findViewById(R.id.tvExplanation);
tvStatus = (TextView) findViewById(R.id.tvStatus);
cbEnabler = (CheckBox) findViewById(R.id.cbEnabler);
wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.startScan();
}
}
But the program already crashes on wifi.startScan();

[Q] Schedule with long delay

Hello guys. I'm making an app, its a kind of alarm scheduler but I have a problem with the code. Thats what im using
Code:
ScheduledThreadPoolExecutor scheduler=new ScheduledThreadPoolExecutor(1);
scheduler.schedule(new Runnable() {
public void run(){
alarm(1);
} }, delay , TimeUnit.SECONDS);
It works for low values of "delay" if I put a high value (11000 for example) and leave the device alone, I think it enters in sleep mode and dont execute the timer.
How can I solve that?
Thanks in advance
I dont know about the scheduler but an alarm manager can wake the phone from sleep if you want. Or run the alarm in the background while asleep
From something awesome
Thanks for your answer, worked for me.
Here's the code, it maybe help others

[Q] Dialog out of Activity

Hello app developers!
I have got serious problem. Every time I call alertdialogs or other dialogs I see them only in activity. But my app needs to show this dialog when user works on phone, that's why it must be shown out of activity. Any ideas?

You cannot do this. There is simply no feature for that. I have had that problem, too.
Use a Notification or a Toast message.
There is a work-around for this. If you run a service, you can technically launch an activity that can resemble this.
I have an app that uses a broadcast receiver to listen for the events I want to alert my user to. I created a custom layout for my alert dialog and then when the event happens, my broadcast receiver calls the activity.

Yes, great idea. Launch a transparent Activity and start a dialog. Set an onDismissListener and close the app when the dialog is closed.

If I start a transparent activity user can't see that it was started as I understand. Can you give code for broadcast receiver maybe I misunderstand something
The broadcast receiver is just the mechanism I use to launch the activity. It is a mere intent that I start from it. Below is the class I use for my alertdialog. You won't be able to cut and paste because I also created my own class to dismiss the activity.
Code:

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);

I understood everything except the way how app switch between position before signal came and required activity with alert dialog in it. As I see this code initialize activity and alert dialog but don't contain switching that I need
Are you asking how I call the dialog? If so, a simple intent from a broadcast receiver.
Code:
Intent i = new Intent(context, SilentDialog.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
I would use the AlertDialog.Builder class for compatibility.
Why not use a notification, I think that is more elegant.
Code:
public class InstalledReceiver extends BroadcastReceiver {
private NotificationManager mNotificationManager ;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
if (BaseActivity.DEBUG) System.out.println("Received Broadcast");
Boolean update = intent.getBooleanExtra(Intent.EXTRA_REPLACING, false);
mNotificationManager = (NotificationManager) context.getSystemService("notification");
SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences(context);
Boolean disabledNotifications = getPrefs.getBoolean("disableNotifications", false);
if (!disabledNotifications && !update) makeNotification(context);
}
private void makeNotification(Context context) {
CharSequence label = context.getString(R.string.labelNotify);
CharSequence text = context.getString(R.string.textNotify);
CharSequence full = context.getString(R.string.fullNotify);
final Notification notification = new Notification(R.drawable.ic_launcher,text,System.currentTimeMillis());
notification.setLatestEventInfo(context,label,full,null);
notification.defaults = Notification.DEFAULT_ALL;
mNotificationManager.notify( 0, notification);
}
}

I agree, but if he wants to use a dialog, we help him to make one.
The bad thing about the dialog is that it will interrupt whatever the user is doing. This could be very annoying. And who wants to use an app which has annoying popups?

When I use this code activity don't shows when I am out of application. For example Handcent SMS when SMS comes to user shows up a great dialog over all windows. My aim is the same thing

Start an Activity. Set a transparent layout. Show a dialog. That will result in what you want.

Ah. You need to call setContentView. Create a transparent View and pass it as a parameter.

Doesn't help:

}
});
// Set the Icon for the Dialog

}
If you use another layout, is the Activity opened?
Is the "Here" written to the log? Is there any Error message?
And I recommend configuring the AlertDialog within the AlertDialog.Builder: http://www.mkyong.com/android/android-alert-dialog-example/
(However, I guess that it will not solve your problem.)

Nav drawer reloads fragments each time it closes...

navList.setAdapter(adapter);
navList.setOnItemClickListener(new AdapterView.OnItemClickListener(){

My watch face is acting weird when selected.

I'm having some trouble. I just added watch view stub to my code so I can support both square and round devices. Everything still works but now when the watch face is selected it takes a few min to show the text. The background shows up right on both dim and awake screens right away. Its just the text that takes a while to appear.
It only does this when first selecting my watch face.
Am I doing something wrong?

[Volley] Main UI extremely slow

In my app i just have a splash screen and a main activity. In the main thread i have three EditText boxes and a spinner with a string array. On clicking the Button, input from three EditText and spinner selection is posted to my mysql database. For the button click network operation, i used Volley since its east and i dont have to use AsyncTask which am not familiar with.
Apart from this, on entering the main UI .. app first check for network connectivity using ConnectivityManager class. After onClick app checks for empty/invalid imputs using TextUtils.
Now the problem is that when i run my app, its very slow and taking upto 65mb of RAM. IS something wrong with my code. Should i run something else as AsynTask ? Can someone check my code and refine it .. thank you

Well it's hard to say what exactly is wrong with it. Maybe text is to long. You can try to measure each operation performance with System.nanoseconds(easiest) and localize the problem first. It would be easier to say what to do with it.
Yes you should try to figure out what part is causing the problem. Try to cut the code down to essentials and measure the execution time. Maybe you will be able to tell what part exactly is not working as wanted.
