Hi I have developed android phonegap app and when dialog is shown and screen orientation changes,showing the error in logcat.How to solve this
Here is my logcat error:
E/WindowManager(5759): Activity com.example.Service.NotificationAlert has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView#412c93c0 that was originally added here

Please tell me the solution.Thanks In Advance.
Here is my code:
AlertDialog alertDialog = new AlertDialog.Builder(NotificationAlert.this).create();
alertDialog.setTitle("Mobilyzer");
msgCountBundle = getIntent().getExtras();
messageCount = msgCountBundle.getInt("Count");
userId = msgCountBundle.getInt("userid");
if (messageCount > 1) {
alertDialog
.setMessage("You have " + messageCount + " New Messages");
} else {
alertDialog.setMessage("You have " + messageCount + " New Message");
}
alertDialog.show();
new Timer().schedule(new task(), 30000);
private class task extends TimerTask
{
public void run()
{
toastHandler.sendEmptyMessage(0);
}
}
private final Handler toastHandler = new Handler() {
public void handleMessage(Message msg) {
if(alertDialog.isShowing())
{
try
{
alertDialog.dismiss();
finish();
Log.i("alertdialog","hide alert dialog");
}
catch(IllegalArgumentException e)
{
Log.e("illegal ","illegal exception in dialog"+e);
}
catch(Exception e)
{
Log.e("illegal ","exception in dialog"+e);
}
}
Log.i("alertdialog","show alert dialog");
}
};
In NotificationAlert Activity you are showing a Dialog that was not dismissed by explicitly calling dismiss() on it when Activity was paused. Keep a reference to your Dialog object and in onPause() call dismiss() on it.
#Override
protected void onPause() {
if (myDialog != null) {
myDialog.dismiss();
}
super.onPause();
}
Check the flow of application .In application you are adding dialog more than one time i think.So, try to solve by adding only one dialog in to activity view.
It is because of some other exception the app is crashing and because the dialog is showing the window leak exception is thrown.
Anyways the window leak exception occurs when the dialog is not null and the activity is finished. So the dialog has to be made null either in onPause() as mentioned above or where the activity is moving to a new screen like before starting an intent. Here you can nullify the dailog in the catch so that the window leak exception can be handled, but there is some other exception in your code. Provide the complete logcat.

I'm developing webview app, the problem in OnJsAlert that when i click on the Dialog it opens after dismiss it and click again it stop my app, for sorry i can't get the problem from debugging.
This is my MainActivity.class
#Override
public boolean onJsAlert(WebView view, String url, final String alertSource, final JsResult alertResult) {
alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
alertDialog.setContentView(R.layout.activity_alert);
alertDialog.setCancelable(true);
TextView alertMessage = alertDialog.findViewById(R.id.alert_text);
alertMessage.setText(alertSource);
alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
alertDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
#Override
public void onCancel(DialogInterface dialog) {
alertResult.cancel();
}
});
alertDialog.show();
return true;
}

Your alertDialog is created before public boolean onJsAlert(...) method called and when it's called second time you got AndroidRuntimeException: requestFeature() must be called before adding content because of you can't use requestWindowFeature() with created dialog. You have to create new instance of dialog in this method or reuse global defined dialog.
I am quite new to android development and I am facing a NullPointerException when I am trying to call an AsyncTask which is an inner class in another class.
I believe it is the way I am instantiating it but this is what I have:
// This onClick is in my adapter class - which is a separate Java File and class
#Override
public void onClick(View v) {
UploadRes uploadRes = new UploadRes();
UploadRes.UploadResConfirm uploadResConfirm = uploadRes.new UploadResConfirm(v.getContext());
uploadResConfirm.execute(fileName, filePath);
}
public class UploadResConfirm extends AsyncTask<String, String, String> {
Dialog dialog;
Context context;
public UploadResConfirm(Context context){
this.context = context;
}
#Override
protected void onPreExecute(){
dialog = new Dialog(UploadRes.this);
dialog.setTitle("Currently uploading");
dialog.show();
}
I believe it has got something to do with the dialog box itself being instantiated in the AsyncTask class.
The error stack trace on Logcat - its the Dialog, I think its in the wrong place...
java.lang.NullPointerException

Some help if any would be much obliged.
Instead of dialog = new Dialog(UploadRes.this);
Try
dialog = new Dialog(context);
your are passing a wrong context to create dialog.
I am beginner and I had a test. I did all tasks, but I have a problem -
public class HttpTask extends AsyncTask<Integer, String, String> {####
ProgressDialog dialog;
Context context;
public HttpTask(Activity activity) {
//init progress dialog
dialog = new ProgressDialog(context);****
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
}
protected void onPreExecute() {
// show progress dialog
dialog.setMessage("Loading...");
dialog.setCancelable(false);
}
protected String doInBackground(Integer... params) {
//freeze system to 5 seconds
try {
int seconds = params[0]*5;####
TimeUnit.SECONDS.sleep(seconds);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(final String success) {
// if there is progress dialog hide it
dialog.dismiss();
}
}
It crashes, when I try to compile it (I showed where are problems with * sign):

Actually, your context is null because you didn't initialize it.
Add one extra line inside your HttpTask:
public HttpTask(Activity activity) {
this.context = activity;
dialog = new ProgressDialog(context);
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
}
and change Context to Activity like this:
Activity context;
Now call this context anywhere in your class.
Yes you must get NullPointer. Because your context is null.
Change this like
public HttpTask(Context _context) {
context = _context;
//init progress dialog
dialog = new ProgressDialog(context);****
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
}
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();
}
}
});
}

You must check activity isFinishing() If the activity is finishing, returns true; else returns false.
