For question 1):

Considering that the error message doesn't seem to say which line of your code is causing the trouble, you can track it down by using breakpoints. Breakpoints pause the execution of the program when the program gets to specific lines of code. By adding breakpoints to critical locations, you can determine which line of code causes the crash. For example, if your program is crashing at a setContentView() line, you could put a breakpoint there. When the program runs, it will pause before running that line. If then resuming causes the program to crash before reaching the next breakpoint, you then know that the line that killed the program was between the two breakpoints.

Adding breakpoints is easy if you're using Eclipse. Right click in the margin just to the left of your code and select "Toggle breakpoint". You then need to run your application in debug mode, the button that looks like a green insect next to the normal run button. When the program hits a breakpoint, Eclipse will switch to the debug perspective and show you the line it is waiting at. To start the program running again, look for the 'Resume' button, which looks like a normal 'Play' but with a vertical bar to the left of the triangle.

You can also fill your application with Log.d("My application", "Some information here that tells you where the log line is"), which then posts messages in Eclipse's LogCat window. If you can't find that window, open it up with Window -> Show View -> Other... -> Android -> LogCat.

Hope that helps!

I had this issue where on a screen orientation change, the activity finished before the AsyncTask with the progress dialog completed. I seemed to resolve this by setting the dialog to null <code>onPause()</code> and then checking this in the AsyncTask before dismissing. 

<pre><code>@Override
public void onPause() {
 super.onPause();

 if ((mDialog != null) &amp;&amp; mDialog.isShowing())
 mDialog.dismiss();
 mDialog = null;
}

... in my AsyncTask:

<pre><code>protected void onPreExecute() {
 mDialog = ProgressDialog.show(mContext, "", "Saving changes...",
 true);
}

protected void onPostExecute(Object result) {
 if ((mDialog != null) &amp;&amp; mDialog.isShowing()) { 
 mDialog.dismiss();

as others have suggested, you should check the status of the activity before performing special operations on your dialogs. 

here's the relavant code, which is the cause to the problem (copied from Android source code) : 

<pre><code>public void updateViewLayout(View view, ViewGroup.LayoutParams params) {
 if (!(params instanceof WindowManager.LayoutParams)) {
 throw new IllegalArgumentException("Params must be WindowManager.LayoutParams");
 }

 final WindowManager.LayoutParams wparams

 ViewRootImpl root = mRoots[index];
 mParams[index] = wparams;
 root.setLayoutParams(wparams, false);

private int findViewLocked(View view, boolean required) {

I am using a custom static class which makes- shows and hides a dialog.
this class is being used by other activities too not only one activiy.
Now the problem you described also appeared to me and i have stayed overnight to find a solution..

Finally i present you the solution!

if you want to show or dismiss a dialog and you dont know which activity initiated the dialog in order to touch it then the following code is for you..

<pre><code> static class CustomDialog{

 public static void initDialog(){
 ...
 //init code
 ...
 }

 public static void showDialog(){
 ...
 //init code for show dialog
 ...
 }

 /****This is your Dismiss dialog code :D*******/
 public static void dismissProgressDialog(Context context) { 
 //Can't touch other View of other Activiy..
 //http://stackoverflow.com/questions/23458162/dismiss-progress-dialog-in-another-activity-android
 if ( (progressdialog != null) &amp;&amp; progressdialog.isShowing()) {

 //is it the same context from the caller ?
 Log.w("ProgressDIalog dismiss", "the dialog is from"+progressdialog.getContext());

 Class caller_context= context.getClass();
 Activity call_Act = (Activity)context;
 Class progress_context= progressdialog.getContext().getClass();

 Boolean is_act= ( (progressdialog.getContext()) instanceof Activity )?true:false;
 Boolean is_ctw= ( (progressdialog.getContext()) instanceof ContextThemeWrapper )?true:false;

 if (is_ctw) {
 ContextThemeWrapper cthw=(ContextThemeWrapper) progressdialog.getContext();
 Boolean is_same_acivity_with_Caller= ((Activity)(cthw).getBaseContext() == call_Act )?true:false;

 if (is_same_acivity_with_Caller){
 progressdialog.dismiss();
 progressdialog = null;
 }
 else {
 Log.e("ProgressDIalog dismiss", "the dialog is NOT from the same context! Can't touch.."+((Activity)(cthw).getBaseContext()).getClass());
 progressdialog = null;
 }
 }


 }
 } 

 }

 dialog = null;

Above solution didn't work for me. So what I did is take <code>ProgressDialog</code> as globally and then add this to my activity

<pre><code>@Override
 protected void onDestroy() {
 if (progressDialog != null &amp;&amp; progressDialog.isShowing())
 progressDialog.dismiss();
 super.onDestroy();
 }
</code></pre>

so that in case if activity is destroyed then the ProgressDialog will also be destroy.
