SecurityException (@Parcel:readException:1327) {AdWorker #1}

From my research, this bug seems to be introduced when admob was integrated into Google Play service. You would see this exception when you use r15, r16 of Google Play services.

Currently, there's no solution. But the Google Team is aimming to fix this in r17.

NullPointerException (@ActionBarImplICS:getThemedContext:287) {main}

This most likely shows up when you are trying to hide the actionbar in your app's activities.

You may be using:

requestWindowFeature(Window.FEATURE_NO_TITLE);

However, you may see NullPointerException (@ActionBarImplICS:getThemedContext:287) {main} when users press the menu button in their devices. Some Android devices have the menu button as the hardware button, while Kindle Fire devices have the menu button as a software button.

To prevent the crash from happening, you can override the menu button key code to do nothing:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
   if ( keyCode == KeyEvent.KEYCODE_MENU ) {
       // do nothing
       return true;
   }
   return super.onKeyDown(keyCode, event);
}

Android Strikethrough HTML not rendering in EditText

I was working on supporting strikethrough in EditText of my app. Using StrikethroughSpan, I was able to show it in the EditText element. This strikethrough is converted to <strike></strike> when you use the toHtml() method.

However, when I try to render the strikethrough back to the EditText, I found the Html.fromHtml method does not support strikethough.

The only way to render the strikethough seems to be through the Webview.
