<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.gpstracking"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="8" />

   <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name="com.seven.gpstracking.AndroidGPSTrackingActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>


    <service android:name=".service" 
              android:label="@string/app_name"
              >
    </service>

    <receiver android:enabled="true" android:name=".BootUpReceiver">

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

    </application>


   </manifest>

The main method is working correctly before i tried to start it on boot. Also the app still working after i ignore the android error on boot (The App Closed)

in the log cat am getting a class not found exception

can you please help ?

Answer 1

In your manifest you have assigned package: com.example.gpstracking. When u then define .BootUpReceiver. The system should expect to locate the class at com.example.gpstracking.BootUpReceiver.

Please try and change the package .BootUpReceiver to the full path com.seven.ex.helper.BootUpReceiver. The same goes for AndroidGPSTrackingActivity as this should be com.seven.ex.AndroidGPSTrackingActivity as far as I can tell.

Answer 2

Your Service won't work like it is at the moment. You will have to move the stuff from onStart() to onStartCommand() and then return whether the service is sticky or not. The problem is that the onStart()-method has a good chance of not getting called at all (as it is deprectaed by now).

@Override
public int onStartCommand(final Intent intent, final int flags, final int startId) {

        //do your stuff here

    return Service.START_NOT_STICKY;
}
