Question:
I have rewritten my question and this time I will be more specific. My problem is that I want to make my application start every time I start my phone. For this I have a java file called bootreceiver.java that has the following:
package my.app.client;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.net.ConnectivityManager;
import android.preference.PreferenceManager;
import android.util.Log;
public class BootReceiver extends BroadcastReceiver {
public final String TAG = BootReceiver.class.getSimpleName();
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "BOOT Complete received by Client !");
String action = intent.getAction();
if (action.equals(Intent.ACTION_BOOT_COMPLETED)) {
Intent serviceIntent = new Intent(context, Client.class);
serviceIntent.setAction(BootReceiver.class.getSimpleName());
context.startService(serviceIntent);
}
}
}
So what I need to know is I have to tell it in my launcheractivity or what steps I should take so that my bootreceiver turns on the application every time I turn on my mobile. As for the manifest, I understand it is just adding:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<receiver android:name="my.app.client.BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
In my case the name of my class is BootReceiver so I would have to put:
<receiver android:name="BootReceiver">
This I will put in the manifest but I don't know what I have to put in my launcheractivity or what I have to do with bootreceiver I just have to add it to the manifest or do I have to do something else?
I have been testing on my phone and muchas veces falla y no se arranca la aplicación there any way to solve it?

If I reformulate the question, it is so that you can explain to me that I am doing wrong from the logcat. Because it shows me not found if in my manifest I have my class.
I have also tried with this and it has not worked:
add the BootReceiver class inside another package, for example:
<receiver android:name="my.app.client.receiver.BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
The project is , that I modify for educational purposes:
This is the project to import, click here
The application is called ZMaster Clean Pro (The application appears at the end), it is a client application, it is in a .zip file so that you can IMPORT BOTH IN ANDROID AND ECLIPSE – The startup is set as a service, the question is that when I open my application is visible, but when I restart in the startup it never opens, but I open it. So the layout of my application should be visible when I turn on my mobile. If you put it as activity, it will return an error in the logcat as I quote.
Answer:
The error is as follows:
Caused by: java.lang.ClassNotFoundException: Didn't find class "my.app.client.receiver.BootReceiver" on path: /data/app/my.app.client-1.apk 01-01 00: 04: 02.830 : E / AndroidRuntime (1464):
You must define the correct package and class in the receiver, apparently it should be:
<receiver android:name="my.app.client.BootReceiver">
In order for your application to run when you fully start your device (BOOT_COMPLETED), it is important to add the permission:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Enable the receiver and add the corresponding intent-filter to start the application when you fully start your device:
<receiver android:enabled="true" android:name=".BootReceiver"
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>
If you define the execution of a BroadcastReceiver from your AndroidManifest.xml , you don't need to start a service, you can directly start the main Activity of your application, therefore the BootReceiver class would be:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class BootReceiver extends BroadcastReceiver {
private static final String TAG = "BootUpReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "* onReceive()");
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
Remember that the complete initialization (BOOT_COMPLETED) takes a few seconds after you see the device turned on, so do not despair.
