Soft keyboard doesn't appear

Question

I'm testing my app on android 4.0.4 Samsung galaxy duos, the problem is if I set:

android:textIsSelectable="true"

the keyboard doesn't appear, though it appears on the emulator. Any suggestions?

Here is how my EditBox looks like

<EditText 

        android:focusable="true"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"        
        android:inputType="textVisiblePassword|textCapWords|textMultiLine"
        android:textIsSelectable="true"
        android:gravity="top|left"
        android:minLines="6"
        android:maxLines="10"
        android:minHeight="140dp"
        android:hint="@string/message"
        />
      <requestFocus />

Add a requestfocus. In xml:

<EditText>
    <requestFocus />
</EditText>  

Programmatically

edittext.requestFocus();

To "force" the SoftKeyboard to appear, you can do it dynamically:

InputMethodManager mImm = (InputMethodManager) 
                        getSystemService(Context.INPUT_METHOD_SERVICE);  
mImm.showSoftInput(SearchEdit, InputMethodManager.SHOW_IMPLICIT);  

Set onFocusChangeListener to appear your keyboard:

edittext.setFocusable(true);  
edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {  
   @Override  
   public void onFocusChange(View v, boolean hasFocus) {  
       if (hasFocus)   
           mImm.showSoftInput(SearchEdit, InputMethodManager.SHOW_IMPLICIT);  
       else  
           mImm.hideSoftInputFromWindow(edittext.getWindowToken(), 0);  
   } 
});
