Android :: Difficulty Displaying Alert Dialog - Why Does This Code Force Close App?
Jul 18, 2010
I'm very new to Android so I've been working primarily with information from the android developer's page. Everything was going great until I added the code from the alert dialog section. The code they give alone gives me an error when I try to run it on the last line, saying I must initialize dialog, but I feel like I'm getting the NullPointerException no matter what the case is.If I don't instantiate "dialog" to "null" at the beginning, I cannot run the program. I'm not even trying to do anything crazy yet, any help would be great because I'm having alot of trouble trying to figure out what exactly this code is trying to do.

In my current application I want to show a dialog having "Force Close" and "Report" option at the time of Unhandled Exception. Could anyone please let me know how to have this dialog? right now if I change default Exception Handler to mine It gets control but I am not able to show any dialog after that. I guess UI thread is already closed by the time handler gets control.

I feel a little bit silly asking this, but I haven't been able to find any answers on my own. My Force Close dialog has a "Report" button. I think it's a great idea, and I wish everyone had it. At first, I thought it must be something I turned on without realizing it, but not only can't I find any setting that I might have touched, I also can't find any reference to this button existing on the Internet. I have a Droid, and I know 4 other people with Droids, and they say they don't have the option to report Force Closes. Am I special? Am I just missing something? The "report" button has been there for at least a few weeks now.When I use the Report button, I get a screen with a "feedback" field and a checkbox for "Include system data". Below that , it says "Information from feedback reports will be shown to the developer of the application." Under that are Preview and Send buttons.As a developer, I've never received one of these reports.I'd try to send a report to myself, but it seemingly only shows the button for apps installed from the market, and I don't know of a way to crash my production app.I suppose I could publish a simple crashing app just to try it out, but I thought I'd ask you folks first.Edit:You can view screenshots here: http://bentobin.com/crashReportImages/

I'd like to use AlertDialog as a Login or pin code or password dialog. Here is my code -
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Login"); alert.setMessage("Enter Pin :");
// Set an EditText view to get user input final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText().toString();
Log.d( TAG, "Pin Value : " + value); return;
} } );
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub return;
} } );
alert.show();
How to code that all input text will appear like ' * ' - asterisk. I can't get my pin code value although it shows into asterisk. my code is below
private void accessPinCode_2() {
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.dialog_login, null);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Login"); alert.setMessage("Enter Pin :");
alert.setView(textEntryView);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//String value = input.getText().toString();
EditText mUserText;
mUserText = (EditText) textEntryView.findViewById(R.id.txt_password);
String strPinCode = mUserText.getText().toString();
Log.d( TAG, "Pin Value : " + strPinCode); return;
} } );
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub return;
} } ); alert.show(); } } dialog_login.xml
<?xml version="1.0" encoding="utf-8"?><EditText xmlns:android="http://schemas.android.com/apk/res/android"
id="@+id/txt_password"
android:password="true"
android:layout_height="wrap_content"
android:layout_width="250px"
android:layout_centerHorizontal="true"
android:layout_below="@+id/password_text"
android:singleLine="true" />
I entered the value, but get null! How to solve? Debugging is stopped at this statement. When I pointed above mUserText null value being shown in popup.
String strPinCode = mUserText.getText().toString();
I use Android 1.6. Does it depend on Version?

How many times have you asked users to send you the logcat result to track down a nasty force-close?How many users have actually replied?It's not that users are lazy or busy.Having to run the "logcat" command or download an external log collector app just means too much trouble for them.It should be much simpler. It should be just one tap.In fact I'm surprised (or being ignorant) that an easier error reporting mechanism has not existed yet in the Android API, especially for the infamous force-close. That is why I coded and open-sourced "Android, send me logs!", a small code library that makes it easy to detect force-close and send logs from within your own apps.You can program it to report errors with just one tap, and also include your own tracing information.

After having solved every of my previous issues to get the code running for retrieving videos from the sdcard and displaying them in the GridView, I still cannot see the videos. I don't know what I have done wrong that they won't show and the array isn't passed on.
This is the java file that tries to retrieve and display the videos from the sdcard in the GridView:

I would like the users of my android app to have the option to email me the stacktrace of any uncaught exception that crashes my app. Originally I thought I would just wrap every entry point to my app in a try/catch block, but there are far too many of these even in my tiny app for this to be reasonable.So what I am really looking for is a way to specify some method to be the default handler for any uncaught exceptions.

I am implementing a custom dialog to form an about screen with a simple look and feel (which may become more complex once I get it working). I have a xml layout that loads some text and an icon from R. However when ever showDialog(int) is called I get a force close. I followed the instructions as per the dev guide:
http://developer.android.com/intl/de/guide/topics/ui/dialogs.html
Code is as follows:
@Override
protected Dialog onCreateDialog(int id) { Dialog dialog;
switch(id) { case DIAG_ABOUT:
dialog = new Dialog(getApplicationContext());
dialog.setContentView(R.layout.aboutdialog);
dialog.setTitle(R.string.about_title);
dialog.setOwnerActivity(this);
break; default: dialog = null;
} return dialog;
} DIAG_ABOUT is defined as private static final int DIAG_ABOUT = 0;
The Log cat shows the following trace:
03-04 11:37:08.760: ERROR/AndroidRuntime(726): Uncaught handler: thread main exiting due to uncaught exception
03-04 11:37:08.780: ERROR/AndroidRuntime(726): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

Does anyone have expirience with opengl-ui-opengl threading interraction? I'am developing a small opengl application. I'am a little bit confused with separate opengl thread. Currently, my application is logically separated in two parts - the controlling one and the rendering one. The controlling part interracts with user - accepting user input, changing activities, dealing with files and so on. The rendering part - just render everything it should. Ok, so when I need to load new texture to opengl (unfortunatelly its large and I cant reduce its size), I'd like to show a ProgerssDialog dialog. Trying to show it from the open gl thread brings me an exception: "Can't create handler inside thread that has not called Looper.prepare()". Because the initiator of loading is in the ui thread (for example - user selected a menu option), I'am opening the dialog, adding the load Runnable to stack on Runnables that will be called in Render.onDrawFrame and passing there a callback that will be executed after texture is loaded.

Believe me, I am not trying to create an invisible AlertDialog. But I believe I have one. I'm not making this up. Behavior: main activity starts and is completely unresponsive. No dialog appears. No Force close/ANR appears even after much time in this state. But if I push the back button, it becomes responsive again. This does not occur when debuggable is true in the manifest, so I can't investigate using the debugger. But I found out the following with log statements. MainActrivity:OnCreate starts another activity, a welcome screen. Main Activity: OnResume is called while the other activity is visible. OnResume creates the dialog and calls dlg.Show(); WelcomeActivity is dismissed. MainActivity:OnResume is called. The OnResume method is smart enough to note that the dialog has already been shown and does not create it again. MainActivity is unresponsive. No dialog in sight. When I push the back button, a log statement confirms that the OnCancelListener is called on the dialog. This is Nexus One with 2.2.1. As cool as an invisible dialog is, I'd rather not have it. Can I fix it?

Is there a way to get alert dialog results inline (like you can with most dialogs)? I want to determine what to do next inwith a dialog, but I can't figure out how to get the results back in the same method that I create the dialog from thus allowing me to continue in my logic flow.
void doStuff() { dlg = CreateDialog() dlg.show(); // shows the dialog and doesn't return till the dialog is dismissed
if dlg.getResults() == this) { doThis(); } else { doThat(); }
}

So I have a fairly simple droid app. Part of it is a waterfall of alertdialog boxes makeing sure everything is ready to show the final display. Example Check GPS If (no GPS){ alert.show} The alert has one button that first dismisses the dialog, then performs the check again, and displays another dialog box if GPS is still not enabled.
This all works great if I go at a normal pace. But if I button mash the alert dialog button, eventually I get many alert dialog buttons on top of each other. The program still works, ya just gotta close all of them. .............

I want to display a multichoice list in an alert dialog box. If I'm using an array to store the list of items, then it is working fine :
d.setMultiChoiceItems(R.array.items,
new boolean[]{false, true, false, true, false, false, false},
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int whichButton,
boolean isChecked) {
/* User clicked on a check box do some stuff */
}
})
But in my case, the item list is dynamic, which I'm geting from a database. The database keeps on updating its contents and hence the list is also updating at a fixed interval of time. So, instead of using an array I would like to use a cursor in the argument of setMultiChoiceItems.
