降低Android应用程序CPU使用率 [英] Reduce app CPU Usage in Android
问题描述
我的应用程序显示了4秒的启动画面,然后打开一个Web视图另一项活动。
我使用一个线程尽快Web视图活动开始溅到屏幕并完成()的第一个活动。我也用类似淡入动画和淡出。
它的CPU使用率是8时23%之间%。什么可能的原因波动。我想降低CPU占用率。
我的第一个活动,显示启动画面和启动Web视图活动 -
公共类MainActivity延伸活动{
螺纹splashThread;
@覆盖
保护无效的onCreate(捆绑savedInstanceState){
super.onCreate(savedInstanceState);
overridePendingTransition(R.animation.fadein,R.animation.fadeout); 。getWindow()requestFeature(Window.FEATURE_NO_TITLE);
getWindow()。setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN); 的setContentView(R.layout.activity_main);
}@覆盖
保护无效调用onStart(){
// TODO自动生成方法存根
// ----------------------------------------- splashThread =新主题(){
公共无效的run()
{
尝试
{
睡眠(1000);
}
赶上(例外五)
{
e.printStackTrace();
}
最后
{
意向意图=新意图(getApplicationContext(),OpenWeb.class);
startActivity(意向);
}
}
};
splashThread.start();
// ----------------------------------------- super.onStart();
overridePendingTransition(R.animation.fadein,R.animation.fadeout);
}
@覆盖
保护无效的onStop(){
// TODO自动生成方法存根
完();
super.onRestart();
}
}
可能是你使用进口的东西想了很多。我听说使用的CPU很多?
进口android.graphics。*
您使用的是AVD?
My app shows a splash screen for 4 seconds and then opens another activity with a web view. I am using a thread to splash the screen and finish() the first activity as soon as web view activity is started. I have also used animations like fade in and fade out. It's CPU usage is fluctuating between 8% to 23%.What could be the reason. I want to reduce the CPU usage. My first activity that shows splash screen and starts web view activity-
public class MainActivity extends Activity {
Thread splashThread;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
overridePendingTransition(R.animation.fadein,R.animation.fadeout);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
}
@Override
protected void onStart() {
// TODO Auto-generated method stub
//-----------------------------------------
splashThread=new Thread(){
public void run()
{
try
{
sleep(1000);
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
Intent intent = new Intent(getApplicationContext(),OpenWeb.class);
startActivity(intent);
}
}
};
splashThread.start();
//-----------------------------------------
super.onStart();
overridePendingTransition(R.animation.fadein, R.animation.fadeout);
}
@Override
protected void onStop() {
// TODO Auto-generated method stub
finish();
super.onRestart();
}
}
Could be that you used alot of imports something like. I heard that uses alot of cpu?
import android.graphics.*
Are you using a AVD?
