# Boot Receiver Testing Guide for DailyNotification Plugin

**Created**: 2025-10-14 05:41:27 UTC  
**Author**: Matthew Raymer  
**Status**: ✅ **PRODUCTION READY**

## 🎯 **Overview**

This guide provides comprehensive testing procedures for the **fixed BootReceiver** that now properly handles Direct Boot and Android 10+ requirements. The BootReceiver works alongside the app startup recovery for maximum reliability.

## 🔧 **What Was Fixed**

### **1. AndroidManifest.xml Updates**
```xml
<receiver
    android:name="com.timesafari.dailynotification.BootReceiver"
    android:enabled="true"
    android:exported="true"
    android:directBootAware="true">
    <intent-filter android:priority="1000">
        <!-- Delivered very early after reboot (before unlock) -->
        <action android:name="android.intent.action.LOCKED_BOOT_COMPLETED" />
        <!-- Delivered after the user unlocks / credential-encrypted storage is available -->
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <!-- Delivered after app update; great for rescheduling alarms without reboot -->
        <action android:name="android.intent.action.MY_PACKAGE_REPLACED" />
    </intent-filter>
</receiver>
```

**Key Changes:**
- ✅ Added `android:exported="true"` (required for API 31+)
- ✅ Added `android:directBootAware="true"` (handles Direct Boot)
- ✅ Added `LOCKED_BOOT_COMPLETED` (early boot recovery)
- ✅ Removed `PACKAGE_REPLACED` (not needed for our use case)

### **2. BootReceiver Implementation Updates**
```java
// Now handles three boot events:
case ACTION_LOCKED_BOOT_COMPLETED:
    handleLockedBootCompleted(context);
    break;
    
case ACTION_BOOT_COMPLETED:
    handleBootCompleted(context);
    break;
    
case ACTION_MY_PACKAGE_REPLACED:
    handlePackageReplaced(context, intent);
    break;
```

**Key Features:**
- ✅ **Direct Boot Safe**: Uses device protected storage context
- ✅ **Early Recovery**: Handles locked boot completion
- ✅ **Full Recovery**: Handles unlocked boot completion
- ✅ **Update Recovery**: Handles app updates

### **3. Exact Alarm Permission Handling**
```java
// Improved exact alarm settings
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
    if (alarmManager.canScheduleExactAlarms()) {
        Log.d(TAG, "Exact alarms already allowed");
        return;
    }
    
    Intent intent = new Intent(Settings.ACTION_REQUEST_SCHEDULE_EXACT_ALARM);
    intent.setData(Uri.parse("package:" + getContext().getPackageName()));
    getContext().startActivity(intent);
}
```

## 🧪 **Testing Procedures**

### **Test 1: Boot Receiver Registration**

**Objective**: Verify BootReceiver is properly registered with all required actions

**Steps**:
```bash
# Check BootReceiver registration
adb shell "dumpsys package com.timesafari.dailynotification | grep -A10 -B5 BootReceiver"
```

```
android.intent.action.LOCKED_BOOT_COMPLETED:
  a440fcf com.timesafari.dailynotification/.BootReceiver filter 4e5fd5c
    Action: "android.intent.action.LOCKED_BOOT_COMPLETED"
    Action: "android.intent.action.BOOT_COMPLETED"
    Action: "android.intent.action.MY_PACKAGE_REPLACED"
    mPriority=1000, mOrder=0, mHasStaticPartialTypes=false, mHasDynamicPartialTypes=false
```

**Success Criteria**:
- ✅ BootReceiver is registered
- ✅ All three actions are present
- ✅ Priority is set to 1000
