如何在設備啓動時啓動服務？

Trying to start a service on boot on Android

廣播接收器

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 

public class StartActivityAtBoot extends BroadcastReceiver{ 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) { 
      Intent i = new Intent(context, CompareIMSI.class); 
      context.startService(i); 
     } 
    } 
} 

CompareSIM.java

import android.app.Service; 
import android.content.Context; 
import android.content.Intent; 
import android.content.SharedPreferences; 
import android.os.IBinder; 
import android.telephony.TelephonyManager; 
import android.widget.Toast; 

public class CompareIMSI extends Service{ 

    Context context; 
    TelephonyManager operator; 

    @Override 
    public IBinder onBind(Intent intent) { 
     return null; 
    } 

    @Override 
    public void onCreate() { 
     super.onCreate(); 
     Toast.makeText(this, "Service Created", Toast.LENGTH_LONG).show(); 
     //compareSIM(); 
    } 

    @Override 
    public void onDestroy() { 
     super.onDestroy(); 
     Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show(); 
    } 

    @Override 
    public void onStart(Intent intent, int startId) { 
     super.onStart(intent, startId); 
     Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show(); 
     compareSIM(); 
    } 

    public void compareSIM(){ 

     final String STORAGE = "Storage"; 
     SharedPreferences unique = getSharedPreferences(STORAGE, 0); 
     final String storedIMSI = unique.getString("simIMSI", ""); 
     final String currentIMSI = getSubscriberId().toString(); 

     if (!storedIMSI.equals(currentIMSI)){ 
      Intent i = new Intent(CompareIMSI.this, ScreenLockActivity.class); 
      startActivity(i); 
     } 
    } 

    public String getSubscriberId(){ 

     String IMSI = null; 
     String serviceName = Context.TELEPHONY_SERVICE; 
     TelephonyManager m_telephonyManager = (TelephonyManager) getSystemService(serviceName); 
     IMSI = m_telephonyManager.getSubscriberId(); 
     return IMSI; 
    } 
} 

我想日e應用程序啓動時啓動compareSIM服務，在啓動過程中，此服務將運行，因爲當前連接的SIM卡IMSI將被檢索並與已保存的IMSI匹配，一旦它們不同，用戶將被帶入登錄佈局。我想引導期間執行此，但未能如願......請諮詢我的編碼，感謝

Answer 1

您需要在Android清單註冊的廣播接收器，像這樣：

<receiver android:name=".StartActivityAtBoot"> 
    <intent-filter> 
     <action android:name="android.intent.action.BOOT_COMPLETED" /> 
    </intent-filter> 
</receiver> 

而且請確保您在清單中擁有此權限：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> 

Answer 2

檢查您的androidManifest文件。您需要在androidManifest文件中添加接收器。

<receiver android:name=".......StartActivityAtBoot" > 
     <intent-filter> 
      <action android:name="android.intent.action.BOOT_COMPLETED" /> 
      <category android:name="android.intent.category.HOME" /> 
     </intent-filter> 
    </receiver> 

Answer 3

floow這些步驟在啓動，說明您的服務：

步驟1：在AndroidManifest.xml中添加BOOT_COMPLETED權限爲：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission> 

步驟2：在AndroidManifest。 xml將您的Reciver註冊爲：

<receiver android:name=".StartActivityAtBoot" android:label="@string/app_name"> 
    <intent-filter> 
     <action android:name="android.intent.action.BOOT_COMPLETED" /> 
     <category android:name="android.intent.category.LAUNCHER" /> 
    </intent-filter> 
</receiver> 

步驟3：在AndroidManifest.xml中註冊您的服務爲：

<service android:name=".CompareIMSI"> </service> 

步驟3：在StartActivityAtBoot啓動的服務爲：

public class StartActivityAtBoot extends BroadcastReceiver 
{ 
    static final String ACTION = "android.intent.action.BOOT_COMPLETED"; 
    public void onReceive(Context context, Intent intent) 
    { 
     if (intent.getAction().equals(ACTION)) 
     { 
        context.startService(new Intent(context, 
        CompareIMSI.class), null); 
      Toast.makeText(context, "CompareIMSI service has started!", Toast.LENGTH_LONG).show(); 
     } 
    } 
} 

這是所有關於啓動服務Boot.Thanks
