I have a PreferenceActivity containing checkboxes amongst other things and worked perfectly. I decided to add an AlertDialog which first prompts the user to ensure they wish to select the check box. Nine times out of 10 everything works fine but on occasion specifically when I try to check a check box as soon as the ActivityPreference has loaded I get the following error when trying to show the dialog:
android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy#45a646d8 is not valid; is your activity running?

I saw this question but the answers didn't appear relevant. Here is my code
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,String key) {
final String k = key;
if (findPreference(key) instanceof CheckBoxPreference) {
final CheckBoxPreference chkPref = (CheckBoxPreference) findPreference(key);
boolean result = sharedPreferences.getBoolean(key,false);
if(result){
new AlertDialog.Builder(AppPreferenceActivity.this)
.setTitle("Confirm Ation")
.setMessage("Do you wish to: " + chkPref.getTitle())
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
pDialog.setMessage("Syncing");
pDialog.show();
new SyncTask().execute(k);
}
})
.setNegativeButton("No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
chkPref.setChecked(false);
}
}).show();
}
}
}
Any help would be much appreciated.

I have a "alertDialogBuilder" to rename an entry when a button is pressed. This works fine when the App is freshly opened. But If I press the back button (meaning the App is minimized and I am back at the Android home-screen), when I relaunch the App and press the button, this time the APP crashes. This happens every time and I have no idea how to debug this. I have checked the lifecycle and "onPause" and "onStop" are called when pressing the back button. But I don't see why that should be a problem.
Any ideas?
Here is the code where I launch the prompt dialogue in a helper class:
public void loadPromptInput(Context promptcontext, final OnOkGetText onOk, String InitialTxt) {
//pathText.setText("Prompt input");
LayoutInflater li = LayoutInflater.from(promptcontext);
View promptsView = li.inflate(R.layout.prompts_dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder( promptcontext);
// set prompts.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialogUserInput);
userInput.setText("");
userInput.append(InitialTxt);
alertDialogBuilder
.setCancelable(false)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
onOk.hereIsYouText(userInput.getText().toString());
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
// make the keyboard shown by default
alertDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}

It would be helpful looking at your code to see where you call:
void loadPromptInput(Context promptcontext...
...most probably you are passing as parameter an instance of a context no more valid.
In any case before calling your method check if the activity is finishing:
//in a fragment
if(getActivity() != null && !getActivity().isFinishing()) {
loadPromptInput(getActivity()...
}
//in an activity
if(!isFinishing()) {
loadPromptInput(this...
}
In my database when a condition is fulfilles i'd like to appear a AlertDialog popup. I've tried to do it in two ways, like this
dataBaseHandler
Cursor c = db.rawQuery(selectQuery, null);
if (c.moveToFirst()) {
result = c.getInt(c.getColumnIndex(KEY_COUPONS_TIMES_TO_USE))
-c.getInt(c.getColumnIndex(KEY_COUPONS_TIMES_USED));
if (result < 4) {
MainActivity alert = new MainActivity();
alert.showAlert();
}
}
MainActivity
public void showAlert() {
AlertDialog.Builder myAlert = new AlertDialog.Builder(this);
myAlert.setMessage("Text").create()
myAlert.show();
}
There's no red errors in the code but when a condition is fulfilled during using the application, critical error appears on the screen. Here's what console says
D/QUERY: UPDATE coupons SET times_used = times_used + 1 WHERE id=1

I have tried also to this around in alternate way

Cursor c = db.rawQuery(selectQuery, null);
if (c.moveToFirst()) {
result = c.getInt(c.getColumnIndex(KEY_COUPONS_TIMES_TO_USE))
- c.getInt(c.getColumnIndex(KEY_COUPONS_TIMES_USED));
if (result < 4) {
PopUpFragment popup = new PopUpFragment();
popup.show(FragmentManager manager, String tag);
}
New java file with Dialog Fragment
public class PopUpFragment extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage("I'm a PopUp")
.setPositiveButton("Button 1", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// POSITIVE BUTTON
}
})
.setNegativeButton("Delete me", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
// Create the AlertDialog object and return it
return builder.create();
}
}
Here i've got some problems with parameters in .show() method.
Any help would be appreciated!
I am using Opencv on my application and it works fine with Android 4.3 but it doesn't even open with Android 6.0.
I looked up for a solution on SO, and found one that says to set the package name. So I did it.
Follow code:
public static boolean initOpenCV(String Version, final Context AppContext,
final LoaderCallbackInterface Callback)
{
AsyncServiceHelper helper = new AsyncServiceHelper(Version, AppContext, Callback);
Intent intent = new Intent("org.opencv.engine.BIND");
intent.setPackage("org.opencv.engine");
if (AppContext.bindService(intent,
helper.mServiceConnection, Context.BIND_AUTO_CREATE))
{
return true;
}
else
{
AppContext.unbindService(helper.mServiceConnection);
InstallService(AppContext, Callback);
return false;
}
}
But now I am getting the following error:
11-18 10:14:43.447 24901-24930/br.com.ibramed.dermos E/AndroidRuntime: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

in the following code:
case InstallCallbackInterface.NEW_INSTALLATION:
{
Looper.prepare();
Log.d("Debug", ""+mAppContext);
AlertDialog InstallMessage = new AlertDialog.Builder(mAppContext).create();
InstallMessage.setTitle("Package not found");
InstallMessage.setMessage(callback.getPackageName() + " package was not found! Try to install it?");
InstallMessage.setCancelable(false); // This blocks the 'BACK' button
InstallMessage.setButton(AlertDialog.BUTTON_POSITIVE, "Yes", new OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
callback.install();
}
});
InstallMessage.setButton(AlertDialog.BUTTON_NEGATIVE, "No", new OnClickListener() {
public void onClick(DialogInterface dialog, int which)
{
callback.cancel();
}
});
InstallMessage.show();
} break;
I have searched and found some people saying to keep track of the main Context, because Threads doesn't have context. But my app already does this and use the main context to create the AlertDialogs and it still doesn't work.
The error is when the app show the AlertDialog.
I really don't know what else to do. Can someone help?
As far as I know in service or Aplication class you cant get context with View for android 6.0, so when OpenCv tries to show AlertDialog it does not know to what activity bind dialog and crashes.
Try to init OpenCv in Activity onCreate method before usage.
My working init method in MainActivity (code on kotlin):
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_9, this, object : BaseLoaderCallback(this#HistoryActivity) {
override fun onManagerConnected(status: Int) {
if (LoaderCallbackInterface.SUCCESS == status)
Log.i(TAG, "OpenCV was loaded")
else
super.onManagerConnected(status)
}
})
}
I have this method in which i want to create an AlertDialog but when I call it the application stops working when it reaches ad.show
public void showSettingsAlert() {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);
// Setting Dialog Title
alertDialog.setTitle("GPS is necessary for Traffic Finder");
// Setting Dialog Message
alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");
// On pressing Settings button
alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
//mContext.startActivity(intent);
startActivity(intent);
}
});
// on pressing cancel button
alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// Create Alert Dialog
AlertDialog ad= alertDialog.create();
// Showing Alert Message
ad.show();
}
I get this:

The Context passed to AlertDialog.Builder seems incorrect. Try YourClass.this instead of mContext.
I have an activity with lot of Dialogs for ex Dialog_1, Dialog_2, Dialog_3, I have implemented a WebView in one of the Dialogs lets say Dialog_2. When navigate through the Dialog's, first time the Dialog_2 with the WebView opens with no problem, but second time when I navigate to Dialog_3 and come back to Dialog_2 OR Dialog_1 to Dialog_2 and touch the WebView I get an error as mentioned bellow.
I have looked at Bad token exception but it does not work still using
if (! this.isFinishing()) {
showDialog(DIALOG_ADD_A_PERSON_BODY_MAP)
}

How do I resolve this error. Your help and suggestions much appreciated.
This happens if your Activity has been killed due to some reason and window token of your activity has expired but you try and access it anyways. So to solve this put this in onPause:
#Override
protected void onPause() {
super.onPause();
if ((progress != null) && progress.isShowing()) {
progress.dismiss();
}
progress = null;
}
