Android BroadcastReceiver not running when designated

Question

I am new to android development, and I have an app that when run from the app icon in the menu / home screens runs just fine. However when I try to make it run on boot completion it crashes (Keeping in mind that if I go back to the Icon it will still work) I am wondering what is wrong here. Keep in mind I am doing testing on my personal phone which is android 2.3 and it is ROOTED. Some how I don't think this should be as hard as it is to do, since 9/10 most android apps work in this way or in a way similar to this. Simply put: What am I doing wrong?

In the mean time here is my code for the Broadcast Receiver:

package path.to.file;

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

public class autoBot extends BroadcastReceiver {
private static final String LOG_TAG = "StartAtBootServiceReceiver";

@Override
public void onReceive(Context context, Intent intent) {
    Log.e(LOG_TAG, "onReceive:");
    if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
        Intent i = new Intent();
        i.setAction("path.to.file.MainActivity");
        context.startActivity(i);
    }
}
}  

As well as the Manifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
installlocation="internalOnly"
package="path.to.file"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="15" />

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

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

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

            <category android:name="android.intent.category.HOME" >
            </category>
        </intent-filter>
    </receiver>
</application>

</manifest>

Answer 1

Is there a specific reason you are adding an action to your intent? If your only aim is to launch your activity at start-up, do this in your BroadcastReceiver:

Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);

Also, remove these lines from your manifest under receiver tag, you won't need them there:

<category android:name="android.intent.category.HOME" ></category>
