a few changes of Android 5.0

标签：

1.Service Intent must be explicit

Intent serviceIntent = new Intent(context,MyService.class);
context.startService(serviceIntent);
Note:Implicit intents with startService are not safe

2.Button Text is always Uppercase

<style name="TextAppearance.Material.Button">
<item name="textSize">@dimen/text_size_button_material</item>
<item name="fontFamily">@string/font_family_button_material</item>
<item name="textAllCaps">true</item>
<item name="textColor">?attr/textColorPrimary</item>
</style>

Using <item name="android:textAllCaps">false</item>

3.Material Design Action Bar 默认是有shadow的，是因为新的elevation API,

action bar style 的xml中，定义elevation 属性为0

or getActionBar().setElevation(0)
