Android Boot auto-start app does not lock screen

Main reference: http://life173.blog.51cto.com/2035365/543916/

Realize the function, start the firstactivity automatically after boot, and do not have to unlock.

Paste out the source code:

This is mainly configured in the configuration file:

  <receiver android:enabled= "true"  android:name= " . Bootupreceiver "            android:permission=" Android.permission.RECEIVE_BOOT_COMPLETED ">             <intent-filter>                     <action android:name= "Android.intent.action.BOOT_ Completed " />                     <category android:name= "Android.intent.category.DEFAULT"  / >            </intent-filter>       </receiver> 

and add Permission:   <uses-permission android:name= "Android.permission.RECEIVE_BOOT_COMPLETED"  />    whole Source: <manifest xmlns:android= "Http://schemas.android.com/apk/res/android"      package= "Com.example.activitytest"     android:versioncode= "1"      android:versionname= "1.0"  >    <uses-sdk         android:minsdkversion= "8"         android: targetsdkversion= " />   <uses-permission android:name=" Android.permission.RECEIVE_BOOT_COMPLETED " />      <application         android:allowbackup= "true"          android:icon= "@drawable/ic_launcher"         android:label= "@ String/app_name "      &Nbsp; android:theme= "@style/apptheme"  >        < Activity             android:name= ". Firstactivity "             android:label=" This is my first activity " >                 <intent-filter >                  <action android:name= " Android.intent.action.MAIN "/>                  <category android:name= "Android.intent.category.LAUNCHER"/>              </intent-filter>                                  </activity>        <receiver android:enabled = "true"  android:name= ". Bootupreceiver "            android:permission=" Android.permission.RECEIVE_BOOT_COMPLETED ">             <intent-filter>                     <action android:name= "Android.intent.action.BOOT_ Completed " />                     <category android:name= "Android.intent.category.DEFAULT"  / >            </intent-filter>             </receiver>             </application></manifest>

Add Bootupreceiver class, firstactivity is the activity you want to start;

package com.example.activitytest;import android.content.broadcastreceiver;import  Android.content.context;import android.content.intent;public class bootupreceiver extends  BroadcastReceiver {     @Override     public void  OnReceive (context context, intent intent)  {         // TODO Auto-generated method stub          intent i = new intent (Context,firstactivity.class);          i.addflags (Intent.flag_activity_new_task);          context.startactivity (i);     }} The class to start:firstactivity.java package  com.example.activitytest;import android.app.activity;import android.content.intent;import  Android.net.uri;import android.os.bundle;import android.view.menu;import android.view.menuitem;import android.view.view;import  Android.view.view.onclicklistener;import android.widget.button;import android.widget.toast;public  class FirstActivity extends Activity {     @Override      protected void oncreate (bundle savedinstancestate) {         super.oncreate (savedinstancestate);         // Requestwindowfeature (window.feature_no_title);//To use menu  comment out this sentence          getwindow (). SetFlags (windowmanager.layoutparams.flag_dismiss_keyguard,                 windowmanager.layoutparams.flag_dismiss_ Keyguard)//Boot not lock screen   set          setcontentview (R.layout.first_ layout);         button button1 =  (Button) Findviewbyid (r.id.button_1);         button1.setonclicklistener (New onclicklistener () {              @Override              public void onclick (VIEW V) {                 //toast.maketext (Firstactivity.this, "you click  Button1 ",  toast.length_short). Show ();                 intent intent = new intent (Intent.ACTION_VIEW);                 intent.setdata (Uri.parse (" Http://www.baidu.com "));//setdata, set data tag    mostly Tel, this can't be less                    startactivity (Intent);             }        });             }     @Override     public  Boolean oncreateoptionsmenu (Menu menu) {         Getmenuinflater (). Inflate (R.menu.main, menu);        return  true;//allow created menus to be displayed     }     @Override     public  boolean onoptionsitemselected (Menuitem item) {         Switch (Item.getitemid ()) {        case r.id.add_item:             toast.maketext (this,  "You click add ", Toast.length_short). Show ();             break;         case R.id.remove_item:             Toast.maketext (this,  "You click remove",  toast.length_short). Show ();             break;         default: break;        }         return true;    }      }

PS: Start the app, you need to solve the screen after a while to start, to start the app will take some time.

In fact, you can also set the lock screen when booting up.

GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD,
WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);//boot-lock screen settings are placed in front of this.

Setcontentview (r.layout.first_layout);
