Huawei Honor 10 Lite No 4g LTE

According to this. the international variant Honor 10 Lite you've got does NOT support 4G with MetroPCS, but apparently it does support 3G with that carrier.

As you're only getting 2G EDGE with this phone on Metro, could be carrier doesn't have 3G service in your area?

Does MetroPCS publish any coverage maps for their network? MetroPCS is an MVNO on the T-Mobile network isn't it?

invoke vittual method java.lang.string java. lang.toString ()' on Null object reference

Bonjour à tous,

Je suis nouveau dans le fabuleux monde de la création d'application android. Je débute avec SKETCHWARE et après avoir suivi un tuto pour créer une base de données avec firebase, en lançant l'application et en allant sur une des pages de mon Menu, cette erreur apparaît :

" Attempt To invoke vittual method java.lang.string java. lang.toString ()' on Null object reference
At
Com.my.newProject.ProduitsActivity
$listview1Adapter.getView(ProduitsActivity.java:293) "


Je ne trouve pas mon erreur,

Pourriez vous m'apporter vos lumières s'il vous plait . Je n'arrive plus à avancer dans mon projet.

Merci d'avance.

Emulator won't display my Hello World app

Since I never seemed to notice any benefit from adding the resources tags and related code, I have removed them. Still I have no ability to bring up my app on the emulator.
Here's my code before removing the resources code: (activity_main.xml)

Code:

How do you delete apps from play store library?

Only one way:!!!

Install “My Phone Explore” in the system.

Install “My Phone Explorer client” from Play Store in your phone

Try to find out the mouse clicking software “AutoMouseKey” or also named as “Automatic Mouse and Keyboard 5.2.9.2” ( find portable cracked version to full access)

Connect the phone via USB ( no other methods wouldn’t works – in Control Phone/Load screen Shot in the My Phone Explore)


After connect the phone go to the phone’s playstore and select the library.

Load screen shot from Tools

Write a script via “Automatic Mouse and Keyboard 5.2.9.2” ( it is very easy ; all are in GUI) (pointing the mouse over the X mark and write delete action via keyboard)

Loop the script, delete all library items one by one.


That’s it..

Help How can I show the time in big numbers while logged-in?

Wait! I got the forum's search feature to work, and I found the answer. You can display the time using a "widget": https://androidforums.com/threads/clock-clock.1119127/

-TC

On Motorola phones that is called the "Time and Weather" widget. Just long-press on the Home screen and scroll down till you see "Time and Weather", then drag it to your home screen.

Android Auto

Im not sure what else would need blue tooth in his case.

You can disable this app. Swipe down, settings, apps&notifications, see all apps, Android Auto

Or there is the "Driving Mode" setting

To set it up on the Pixel 3:

  1. Open the Settings app.
  2. Tap Connected devices > Connection preferences > Driving mode.
  3. Tap Behavior. Choose 'Open Android Auto' or 'Turn on Do Not Disturb'
  4. Tap Turn on Automatically. Choose how you would like your phone to detect driving.

Passing an object of a Usb Service to another activity

Hello,
I'm new to Android development and I'm attempting to pass an object of a USB service from one activity to another.

I've attempted to do it two ways thus far. Implementing Parcelable and Implementing Serializable. Both means cause the system to throw and exception. In regards to Serializable, it threw an IOException.

Here is the code for my USBService, care of Felhr85.

. When I attempt to pass the Object itself I do the following.

Code:
private UsbService usbService;
...
Button swchBtn = (Button) findViewById(R.id.buttonSwitch);
        swchBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick (View v)
            {

                if(usbService != null)
                {
                    Intent swIntent = new Intent(MainActivity.this, SecondActivity.class);
                    swIntent.putExtra("USBService", usbService);
                    startActivity(swIntent);
                }
            }

before I switch activities I have done a quick check to make sure that it wasn't equal to "null". I'll change it up later and say if it is equal to null then I'll jump over but I won't send a intent extra. But for now it just crashes every time.

Any insight?

Send UDP from Application

Hello ,
I'm new at android\java so be patient :)

I want to create a small application that send a udp string to my server when I press the button.
everything is working - but it doesn't seem to send
this is what I have

btnAction.setOnClickListener(new View.OnClickListener() {
@ override
public void onClick(View v) {

try {

String messageStr = "test!";
int server_port = 1111;
DatagramSocket s = new DatagramSocket();
InetAddress local = InetAddress.getByName("My.Public.Server.IP");
int msg_length = messageStr.length();
byte[] message = messageStr.getBytes();
DatagramPacket p = new DatagramPacket(message, msg_length, local,server_port);
s.send(p);
}
catch (Exception e) {

}



}
}

whant could be the reason for it?

Thanks ,

Help Getting google calendar to see hotmail calendar on 10+

That's possible: I would never have considered configuring on a PC as I don't use Outlook on a computer. Back when I last had Outlook installed on my phone there was no such option (believe me, I looked!), but that was a couple of years ago.

(My MS account primarily exists as a backup: I've had Google's subscriptions to shared (non-Google) calendars fall over a few times over the years, so like to have an alternative I can switch to by just toggling visibilities. Plus I refuse to be dependent on any individual company, so for anything important I always have alternatives in place).

Help Transferring files to and from Acer Iconia7 tablet

Hi again, if somebody is out there :rolleyes:,
Earlier I said I can access the file directory in the tablet by way of Storage/Apps/Running/File Manager/LAUNCH/usbotg-sda1/

Now, today, the File Manager step is no longer offered in this series. How can this change? But I have discovered it in the main Apps menu and I am working on discovering how to download files from the USB-OTG drive to the tablet.
This is not yet clear to me: can someone please help?

"my project"? Is this an app or something you're developing? Maybe there's a problem with your code?
