You can use 

`mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);`

 to lock your `DrawerLayout` so it won&#39;t be able to open with gestures. And unlock it with: 

`mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);`

Here you can find more info about `DrawerLayout`: [Android API - DrawerLayout][1]

The default version of the webbrowser control in a C# [Windows Forms][1]
application is 7. I have changed to 9 by the article *[Browser Emulation][2]*, but how is it possible to use the latest version of the installed Internet Explorer in a webbrowser control?

Use latest version of Internet Explorer in the webbrowser control

I am trying to do something like this:

    #include &lt;iostream&gt;
    #include &lt;random&gt;
    
    typedef int Integer;
    
    #if sizeof(Integer) &lt;= 4
        typedef std::mt19937     Engine;
    #else
        typedef std::mt19937_64  Engine;
    #endif
    
    int main()
    {
        std::cout &lt;&lt; sizeof(Integer) &lt;&lt; std::endl;
        return 0;
    }

but I get this error:

    error: missing binary operator before token &quot;(&quot;

How can I correctly make the conditional typedef?

I spent quite sometime figuring how to set up adb on Mac, so I figure writing how to set it up might be useful to some people. adb is the command line tool to install and run android apps on your phone/emulator

I&#39;ve already got a DatePicker which pops up when the user clicks on the EditText field

    eReminderDate.setOnClickListener(new OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    //To show current date in the datepicker
                    Calendar mcurrentDate = Calendar.getInstance();
                    int mYear = mcurrentDate.get(Calendar.YEAR);
                    int mMonth = mcurrentDate.get(Calendar.MONTH);
                    int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);
    
                    DatePickerDialog mDatePicker;
                    mDatePicker = new DatePickerDialog(AddReminder.this, new OnDateSetListener() {
                        public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) {
                            // TODO Auto-generated method stub
                        /*      Your code   to get date and time    */
                            selectedmonth = selectedmonth + 1;
                            eReminderDate.setText(&quot;&quot; + selectedday + &quot;/&quot; + selectedmonth + &quot;/&quot; + selectedyear);
                        }
                    }, mYear, mMonth, mDay);
                    mDatePicker.setTitle(&quot;Select Date&quot;);
                    mDatePicker.show();
                }
            });

I&#39;ve tried doing a TimePicker in a similar way but was unable to get it working. This is my attempt at getting it working

     eReminderTime.setOnClickListener(new OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Calendar mcurrentTime = Calendar.getInstance();
                    int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
                    int minute = mcurrentTime.get(Calendar.MINUTE);
                    TimePickerDialog mTimePicker;
                    mTimePicker = new TimePickerDialog(AddReminder.this, new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                            eReminderTime.setText( &quot;&quot;selectedHour + &quot;:&quot; + selectedMinute);
                        }
                    }, hour, minute);
                    mTimePicker.setTitle(&quot;Select Time&quot;);
                    mTimePicker.show();
    
                }
            });

Is it impossible to do it similar to the way I did it for DatePicker?

I&#39;ve tried even just making a TimePicker pop up once the EditText field is clicked with this code.

          eReminderTime.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                showDialog(TIME_DIALOG_ID);
            }
        });

For some reason when I entered that into Android Studio the &#39;showDialog&#39; was scored out.


Can anyone give me tips on where I&#39;m going wrong? Or am I just going to have to use a Custom DialogFragment?

TimePicker Dialog from clicking EditText

Device used for testing: Nexus 4, Android 4.3

Connection is working fine but the `onCharacteristicChanged`Method of my callback is never called. However I am registering for notifications using `setCharacteristicNotification(char, true)` inside `onServicesDiscovered` and that function even returns true.

Device log (there are actually _no_ messages at all when notifications _should_ appear / are sent via the Bluetooth device):

GATT Notifications work fine using iOS and the app basically does the same as on Android (registering for notification etc.).

Has anyone else experienced this with a possible solution?

Android BLE API: GATT Notification not received

So I added gson-2.2.4.jar to the libs dir (I&#39;m using android studio). My project couldn&#39;t find the Gson stuff so I added it as a library dependency to my module in the &quot;Project Structure&quot;. When I try to run the project, the build is failing with the following errors:

    Error:(12, 23) Gradle: package com.google.gson does not exist
    Error:(37, 3) Gradle: cannot find symbol class Gson
    Error:(37, 19) Gradle: cannot find symbol class Gson

Why can&#39;t I get this working? I read elsewhere that Gradle is supposed to handle everything automatically if it&#39;s put in the lib dir.

Android Gradle cannot find symbol class Gson

I&#39;m using the new v7 appcompat library available starting from Android 4.3 (API level 18).

Regardless of what is specified in showAsAction for a menu item, it&#39;s not shown - it always creates the overflow menu icon, and puts even a single menu item under the menu.

Trying to add menu to an activity like this:

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_sizes, menu);
        return true;
    }

And here&#39;s my menu xml:

    &lt;menu xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
        &lt;item android:id=&quot;@+id/menu_add_size&quot;
            android:title=&quot;@string/menu_add_item&quot;
            android:orderInCategory=&quot;10&quot;
            android:showAsAction=&quot;always&quot;
            android:icon=&quot;@android:drawable/ic_menu_add&quot; /&gt;
    &lt;/menu&gt;

Is it a bug of the new support library v7, or just something wrong with the code?
I&#39;ve been using the similar code with ActionBarSherlock many times before.
