Start activity on boot

Question

I'd like to start my app just after the phone boot. Apparently the app is started after the boot but it immediately crashes (just to be clear the app normally works fine). I have already read and tried different solutions (link1, link2) and actually the same code works fine with another app I was developing. Here's the code:

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.bluetoothx10y"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="6"
        android:targetSdkVersion="15" />

    <uses-feature android:name="android.hardware.usb.accessory"/>
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >

        <receiver
            android:name=".StartMyActivityAtBootReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>


        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="landscape" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

            <intent-filter>
               <action android:name="android.hardware.usb.action.USB_ACCESSORY_ATTACHED"/>
            </intent-filter>

            <meta-data 
                android:name="android.hardware.usb.action.USB_ACCESSORY_ATTACHED"
                android:resource="@xml/accessory_filter">
            </meta-data>

        </activity>

        <activity android:name=".DeviceListActivity"
              android:label="@string/app_name"
              android:theme="@android:style/Theme.Dialog"
              android:screenOrientation="landscape" />        
    </application>

</manifest>

StartMyActivityAtBootReceiver.java:

    public class StartMyActivityAtBootReceiver extends BroadcastReceiver {    
    @Override
    public void onReceive(Context context, Intent intent) {

        if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {    

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

            }    
    }   
}

Could it be related the fact that I'm using the a lot of user permissions?

Answer 1

I managed to solve the problem. Inside the OnCreate() I had this code (related to the USB communication) which was causing the crash:

    act_string = getIntent().getAction();
    if( -1 != act_string.indexOf("android.intent.action.MAIN")){
        restorePreference();
    }           
    else if( -1 != act_string.indexOf("android.hardware.usb.action.USB_ACCESSORY_ATTACHED")){
        cleanPreference();
    }   

Deleting this code solved the start after boot issue.
