also true for static,final, constants).Often estimatedBefore you start optimization, make sure you have a problem to solve: Make sure you can measure your existing performance accurately, or you will not be able to observe the improvements brought about by optimization.The datum point is created by the caliper's Micro datum frame. The datum points are hard to get right, so caliper does the hard work, even when you're not measuring where you want to measure it. We strongly recommend that you use

Local Reference changes in ICS for more information. checking reference types by Getobjectreftype Prior to Android 4.0, Getobjectreftype was not implemented correctly due to the use of direct pointers. We find through weak global tables, parameters, local tables, and global tables. First it will find your direct pointer and return the type of reference it checks. This means that if you function Getobjectreftype on a global jclass, and this jclass is passed to a static local

using animations on Textureview, some special transition types may not produce the desired effect. Classes that inherit from Adapterview, such as the ListView, manage sub-view in a way that is incompatible with the transition framework. If the view action is animated on top of Adapterview, the device interface may be suspended. If you want the resize animation to work on TextView, the text on the TextView is drawn to a new position before the animation is complete. To avoid this problem

) { mHeadlineSelectedListener.onHeadlineSelected(position); } } ...}Handling Screen configuration changesIf you use a separate activity to implement a separate part of the UI, remember to respond to certain configuration changes, such as screen rotation, to maintain UI consistency.For example, a 7-inch tablet that runs an Android 3.0 system, the news reader app uses the content of separate activity display articles in vertical mode, but uses multi-panel mode in horizontal

lines and curves to the Path object, and then draw the shapes with the DrawPath () method. Just these base shapes can define their path style through the SetStyle () method. You can define a gradient fill pattern by creating a LinearGradient object. Call the Setshader () method to populate the shape. Draws a bitmap by using the Drawbitmap () method. For example, the following code is used to draw a piechart. It mixes text, lines, and shapes.protected void OnDraw(Canvas canvas) {Sup

Set the ACTIVITY to start a new, empty task stack by calling the SetFlags () method and setting the Flag_activity_new_task and Flag_activity_clear_task flags. C. Set the options you need for intent. D. Create a pendingintent from intent by calling Getactivity (). You can use this pendingintent as a parameter to the Setcontentintent () method.

their properties directly. Instead, you can use Valueanimator to make changes. In the following example, modifying the currently selected pie chart will cause the entire pie to rotate, so the selected point appears to be in the middle of the pie chart. Valueanimator changed the rotation time by hundreds of milliseconds.mAutoCenterAnimator = ObjectAnimator.ofInt(PieChart.this"PieRotation"0);mAutoCenterAnimator.setIntValues(targetAngle);mAutoCenterAnimator.setDuration(AUTOCENTER_ANIM_DURATION);mA
