I have a splash screen in which i am checking user is logged in or not if logged in go to dashboard otherwise go to login activity. I am using sharedpref. Issue is (which I am unable to resolve) after splash screen login screen appears for a brief moment than dashboard. Splash > Login > Dash what i Want is Splash > Dash (if user logged in). Login is the main activity of my project. Here is the code:
public class SplashScreen extends AppCompatActivity {

sessionManager = new SessionManager(this);
broadcastReceiver = new CheckNetStatus();
broadcastIntent();
}
#RequiresApi(api = Build.VERSION_CODES.M)
#Override
protected void onResume(){
super.onResume();
new CheckNetStatus().onReceive(SplashScreen.this,new
Intent(ConnectivityManager.CONNECTIVITY_ACTION));
try {
prefs = getSharedPreferences(SessionManager.PREF_NAME, 0); // Declare
SharedPreferences
accessID = prefs.getInt(SessionManager.KEY_ACCESSID, 0); // get Access Id from
SharedPreferences
isLogin = Utils.getLoginStatus(SplashScreen.this); // Check Login is true or false

Hei there,
I m trying to make an App with Android-Studio that can record sound using a Bluetooth-HS.
I know there are a lot of posts close to this, but i tried all the answers and it wont work for me.
My code gives me back a filled bytebuffer, however testing proves, its always the Phones Mic not the Headset-Mic.
If anyone could take a look at my code and point out why it wont use the BT-HS, that would be a huge help for me.
public class Inhalation extends AppCompatActivity {

I'm trying to first create an activity, then after 2 seconds, I want to hide the action bar and then after another 2 secs, I want to start another activity but this code - getActionBar().hide() isn't working. Here is my code -
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
//final ActionBar actionbar = getActionBar();
Thread timer1 = new Thread() {
public void run(){
try{
sleep(2000);
} catch(InterruptedException e){
e.printStackTrace();
} finally{
getActionBar().hide();
}
}
};
timer1.start();
Thread timer2 = new Thread() {
public void run(){
try{
sleep(2000);
} catch(InterruptedException e){
e.printStackTrace();
} finally{
Intent intent = new Intent("app.lost_and_found_0.STARTINGPOINT");
startActivity(intent);
}
}
};
timer2.start();
}
Is there something wrong I'm doing wrong?
My application theme is set to Theme.Holo.Light in manifest file.
Use getSupportActionBar() instead of getActionBar(). As on the class, you need to extend ActionBarActivity.
I have this code which is an Activity that when started will check for internet connection, if there is a connection, then life goes on. Else a dialog appears to turn on the connection. However I made a thread that each 10 seconds will check for connection and in case the connection was lost it will display the dialog again.

I googled alot, I am already using the cliche answer of runOnUiThread, but it doesn't fix it.
What am I missing?
The way you are checking the internet I guess you are causing your UI thread to sleep. You should do it like this.
Create one Handler and Thread running flag:
Handler mHandler = new Handler();
boolean isRunning = true;
Then, use this thread from your onCreate() method :
new Thread(new Runnable() {
#Override
public void run() {
while (isRunning) {
try {
Thread.sleep(10000);
mHandler.post(new Runnable() {
#Override
public void run() {
if(!HomeScreen.this.isInternetAvailable()){
if (!networkSettingsDialogOpened)
HomeScreen.this.createNetErrorDialog();
}
}
});
} catch (Exception e) {
}
}
}
}).start();
Change this method slightly
private boolean isInternetAvailable() {
try {
final InetAddress ipAddr = InetAddress.getByName("google.com");
if (ipAddr.equals("")) {
return false;
} else {
isRunning = true;
return true;
}
} catch (Exception e) {
return false;
}
}
You can't call Thread.sleep() from code that is running on the UI thread. This is your code:
this.runOnUiThread(new Runnable() {
#Override
public void run() {
while (!HomeScreen.this.isInternetAvailable()) {
if (!networkSettingsDialogOpened)
HomeScreen.this.createNetErrorDialog();
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
You jest need to run the bit of code that shows the Dialog on the UI thread. Try this instead:
new Thread(new Runnable() {
#Override
public void run() {
while (!HomeScreen.this.isInternetAvailable()) {
if (!networkSettingsDialogOpened)
// Show the Dialog on the UI thread
HomeScreen.this.runOnUiThread(new Runnable() {
#Override
public void run() {
HomeScreen.this.createNetErrorDialog();
}
});
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
I want to create a MIDlet which automatically starts using push registry function
PushRegistry.RegisterConnection("sms://:50000", this.getclass().getname(),"*");
Following is the code which I have come up with, and cannot find the problem with it as it is not responding in any way to any message.
P.S. I am aware of the fact that dynamic registration requires me to first run the app once.
public class Midlet extends MIDlet implements CommandListener,Runnable {
private Display disp;
Form form = new Form("Welcome");
Command ok,exit;
public void startApp() {
String conn[];
exit= new Command("exit",Command.CANCEL,2);
ok= new Command("ok",Command.OK,2);
form.addCommand(ok);
form.addCommand(exit);
form.setCommandListener(this);
conn = PushRegistry.listConnections(true);
disp=Display.getDisplay(this);
disp.setCurrent(form);
form.append("Midlet");
form.append("Press OK to register sms connection");
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
notifyDestroyed();
}
public void commandAction(Command c, Displayable d) {
if(c.getLabel().equals("exit"))
{
System.out.println("exit pressed");
destroyApp(true);
}
if(c.getLabel().equals("ok"))
{
String[] cn;
cn=PushRegistry.listConnections(true);
form.append(""+cn.length);
for(int i=0;i<cn.length;i++)
{
form.append(cn[i]);
}
Thread t = new Thread(this);
t.start();
}
}
public void run() {
try {
PushRegistry.registerConnection("sms://:50000",this.getclass().getname, "*");
} catch (IOException ex) {
ex.printStackTrace();
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
}
}
}
Your code worked when I replaced this line PushRegistry.registerConnection("sms://:50000",this.getclass().getname, "*");
with PushRegistry.registerConnection("sms://:50000",<actual name of the class>, "*");
everyone! I need to make a Button disabled for 5 seconds, and the caption of the button must be "Skip" plus the time the button will stay disabled.
I have made a class CTimer that extends Thread, and defined the run method with run(Button). The run method receives the Button which Caption will be modified and is as follows:
public void run(Button skip){
for ( int i=5; i<0; i--)
{
skip.setText("Skip (" + i + ")");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
skip.setEnabled(true);
}
The problem is that the code does not work, any thouhts, anyone?
I have tried the following code & it works fine for me:
public class Main_TestProject extends Activity
{
private Button b;
private int index = 5;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
b = (Button) findViewById(R.id.my_button);
b.setEnabled(false);
hHandler.sendEmptyMessage(0);
}
private Handler hHandler = new Handler()
{
#Override
public void handleMessage(Message msg)
{
if(index > 0)
{
try
{
b.setText("Skip (" + String.valueOf(index) + ")");
index--;
Thread.sleep(1000);
hHandler.sendEmptyMessage(0);
}
catch (InterruptedException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else
{
b.setEnabled(true);
}
}
};
}
