The api isApiSupported return true but SipManager newInstance still return null in Android native Sip

I used Android native Sip api to initialize Sip client.Because I am confused to Sip protocol,I read the android developer document about sip and follow it.When I run my application on Nexus5,it work normally,but when I run it on other device like coolpad, it throw NullPointException from SipManager.The following is my code.For some reason,the username,passwd and domain is private.
public static SipManager manager;
public static SipProfile me;
public static String username;
public static String passwd;
public static void initializeSip(Context context) {
System.out.println("initializeSip");
if (manager == null) {
manager = SipManager.newInstance(context);
}
if (me != null) {
closeLocalProfile();
}
username = SharedPreferences.getLoginInfo().getModel().getVos_phone();
passwd = SharedPreferences.getLoginInfo().getModel().getVos_phone_pwd();
try {
if (!(SipManager.isApiSupported(context) && SipManager.isVoipSupported(context))) {
System.out.println("cannot support");
return;
}
System.out.println("isApiSupported="+SipManager.isApiSupported(context));
System.out.println("SipManager="+SipManager.newInstance(context));
SipProfile.Builder builder = new SipProfile.Builder(username, domain);
builder.setPassword(passwd);
me = builder.build();
manager.open(me);
SipRegistrationListener listener = new SipRegistrationListener() {
#Override
public void onRegistering(String localProfileUri) {
System.out.println("Registering with SIP Server");
}
#Override
public void onRegistrationDone(String localProfileUri, long expiryTime) {
System.out.println("Register success");
}
#Override
public void onRegistrationFailed(String localProfileUri, int errorCode, String errorMessage) {
System.out.println("Registeration failed.Please check Settings.");
System.out.println("errorCode="+errorCode);
System.out.println("errorMessage="+errorMessage);
}
};
manager.setRegistrationListener(me.getUriString(),listener);
manager.register(me,3000,listener);
} catch (ParseException e) {
e.printStackTrace();
} catch (SipException e) {
e.printStackTrace();
}
}
The following is my logcat. Most strangely,I find that the api isApiSupported return true and the SipManager object is not null.I cannot find the reason about it.

Seems an issue of IabHelper. The method queryIntentServices returns a null, instead an empty list.
Try to update the code from this:
Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {
// service available to handle that Intent
mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
}
else {
// no service available to handle that Intent
if (listener != null) {
listener.onIabSetupFinished(
new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,
"Billing service unavailable on device."));
}
}
to this:
Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
List<ResolveInfo> intentServices = mContext.getPackageManager().queryIntentServices(serviceIntent, 0);
if (intentServices != null && intentServices.isEmpty() == false) {
// service available to handle that Intent
mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
}
else {
// no service available to handle that Intent
if (listener != null) {
listener.onIabSetupFinished(
new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,
"Billing service unavailable on device."));
}
}

runOnUiThread: Cant touch the View, Exception

I know this has been posted multiple times now, but nothing seemed to fix my problem. I create a Loading Dialog on the UI thread, then start another thread which is doing some networking stuff and via interface, the class gets a callback, when networking is done. The problem is, after its done, i cant remove the loading dialog, even with "runOnUIThread". Here is the code:
public void onClickLoginButton (View view) {
if (!((EditText)findViewById(R.id.textNickname)).getText().toString().isEmpty() &&
!((EditText)findViewById(R.id.textPassword)).getText().toString().isEmpty()) {
loggingIn = new ProgressDialog(this);
loggingIn.setTitle("Login");
loggingIn.setMessage("Wait while logging in...");
loggingIn.show();
final LoginInterface callbackInterface = this;
new Thread(new Runnable() {
public void run() {
Networking net = new Networking();
net.Login(((EditText) findViewById(R.id.textNickname)).getText().toString(), ((EditText) findViewById(R.id.textPassword)).getText().toString(), callbackInterface);
}
}).start();
}
}
And this is the function that gets called by the networking stuff, after its done:
#Override
public void LoginCallback(final boolean loginSuccess, final boolean isActivated) {
loggingIn.hide();
loggingIn = null;
final Context context = this;
runOnUiThread(new Runnable() {
#Override
public void run() {
if (loginSuccess && isActivated) {
loggingIn.hide();
loggingIn = null;
finish();
} else if (loginSuccess == false) {
Toast.makeText(context, "Login failed! User/Password wrong", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(context, "Login failed! Account not activated", Toast.LENGTH_SHORT).show();
}
}
});
}
And this is the stack trace:

You are calling the loggingIn.hide() method twice, and the first time not on the UI thread. Change your code to this:
#Override
public void LoginCallback(final boolean loginSuccess, final boolean isActivated) {
final Context context = this;
runOnUiThread(new Runnable() {
#Override
public void run() {
if (loginSuccess && isActivated) {
loggingIn.hide();
loggingIn = null;
finish();
} else if (loginSuccess == false) {
Toast.makeText(context, "Login failed! User/Password wrong", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(context, "Login failed! Account not activated", Toast.LENGTH_SHORT).show();
}
}
});
}

NullPointException on algorithm but don't get NPE on same algorithm in another spot in same class [closed]

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

Closed 9 years ago.
In my app, the user has 3 different types of quizzes they can choose. When they choose one of quiz types called "levels", I get a NullPointerException. The order of the algorithm for "levels" is the same as when the game type is "original". You can see this in the code below. It is hard to explain why the algorithms are the same so I will spare you those details but just accept the algorithms are the same for now. :)
Why am I getting this NPE exception with the quiz/game type is "levels" but not when the quiz/game type is "original" even though the code/algorithm for them are the same?

Here's the problem:
Caused by: java.lang.NullPointerException
06-14 20:44:45.413: E/AndroidRuntime(1335): at matt.lyons.bibletrivia.lite.QuestionView.loadLevelsQuizTen(QuestionView.java:195)
Go to line 195 in the QuestionView.java file, look at the object references on that line, and see which one you failed to initialize.
The sooner you stop telling yourself that everything is fine and start looking at what's really happening, the sooner you'll fix the problem and move on.
You should not be duplicating any code. You should encapsulate it in a single method call and calling it in both places. This is a recipe for error.
You have lots of other issues. You use a private data member i to do different things in different methods. It's not synchronized in any way that I can see. I see no reason why that value couldn't be a method parameter and passed in. That would be more more thread safe.
When you're doing things like that, comparing Strings with ==, and duplicating code it puts everything you've done in doubt for me. No wonder you're having trouble. Voting to close.

Set a breakpoint where you are getting the NPE and check the values of your variables. I would guess either queries is null (not setting or getting from intent bundle correctly), or queries.get(i) is null.

you get the error because you are calling 2 different methods. In levels you call loadLevelsQuizTen();, in original you call loadOriginalQuiz();
Despite the fact you say they are the same, they aren't. I'd use a debugger to step through the method and figure out what is null and why.
