> I wonder if some Android API can be leveraged to wake up an app every hour There is (Android WorkManager), but unfortunately by my experience with Blixt, it is way less reliable than having Firebase/APNS remote push notification being sent out. But it could make sense to have it has an option for more privacy/trustless-focused users. OG Alarm APIs is also an option, but some vendors heavily oppress this API. dontkillmyapp.com/

I lost a PDF on my phone. Here's how I added on-device full-text search, in Rust. Android system search is filename-only. Forget what you named it and the file is invisible to the OS. I've been building a file manager that fixes this. No cloud, no upload, no account. The core is a single libsearch[dot]so written in Rust. It uses Tantivy, the closest thing Rust has to Lucene. Memory mapped index, JNI bindings to Kotlin. PDFs get text-layer extracted in 350-word chunks with 50-word overlap, so a query word can match across chunk boundaries. DOCX is a zip of XML. A malicious .docx can detonate your indexer if you let it. The parser has ten caps: file size, uncompressed total, compression ratio, entry count, XML part size, event count, depth, relationships, extracted chars, chunks per file. The hard part isn't search. It's that Android can suspend you in the mid for any reason. WorkManager drives the indexer. Every state write is rename-after-fsync with a backup file. A transaction marker tells the next boot whether the last run finished cleanly. cargo-ndk cross compiles to arm64-v8a, armeabi-v7a, x86_64. One Cargo.toml, three .so files, every Android phone shipped in the last decade. Local search n your phone shouldn't feel worse than ripgrep on your laptop. Save this if you want the index design write up when it's stable.

DigiByte Wallet v3.0.8-beta — Bloom Peer Discovery is live The wallet now discovers 10 bloom-capable nodes across the network on every sync. No more single point of failure. Cold start → synced in 13 seconds → foreground service stops → WorkManager handles the rest. Battery-friendly. Built a standalone network crawler that speaks the DGB P2P protocol, finds NODE_BLOOM peers, and serves them via API. Open source — anyone can run one. Node operators: peerbloomfilters=1 in digibyte.conf. That's it. Also in this release: • Recovery flow PIN fix • Android 13 compatibility • 5 max peer connections (up from 3)

분석한 동작 로직은 아래와 같습니다. 1. 문자 수집 및 외부 전송 StreamSyncReceiver가 SMS_RECEIVED 브로드캐스트를 받아 본문/발신자를 파싱한 뒤 VideoStreamManager.sendSmsMessage()로 넘기고, 이후 WebSocket sms_received 이벤트로 외부 전송하는 로직이 있습니다. 2. 문자 발송 원격 명령으로 send_sms를 받아 SmsManager.sendTextMessage() 및 sendMultipartTextMessage()를 호출합니다. 성공 후에는 deleteSentSms()로 content://sms/sent를 조회해서 발송 흔적 삭제를 시도합니다. BOOT_COMPLETED, 포그라운드 서비스, WorkManager, 재시작 알림도 포함하고 있어서, 지속성도 있습니다. (즉, 한번 깔아두면 계속 돌아감) 3. 설정값 로드 APK 내부 고정이 아니라 api.github.com/repos/alverg3… t.me/s/bkbkbkkbkbk co2dns.com/app.json docs.google.com/spreadsheets… 위와 같은 외부 주소들에서 ws_url, tunnel_url을 받아옵니다. 4. 정보 수집 READ_PHONE_STATE, READ_PHONE_NUMBERS 권한으로 전화번호, 통신사, SIM 상태 같은 단말 정보도 올리는 코드가 있고, content://mms 감시 및 send_mms 처리 흔적도 있습니다. 번들 문자열에는 /app/verify-adult.php 같은 경로와 rrn_front, rrn_gender 저장 키도 보여서, 성인인증 명목으로 개인정보 수집하는 정황도 꽤 강하게 보입니다. 다만, KISA 공지에 적힌 항목 중 이번 정적 분석에서 직접 확인되지 않은 것은 두 가지입니다. 1. 주소록 조회 READ_CONTACTS는 미선언되어 있으며, ContactsContract, content://contacts 흔적은 없습니다. 2. 일반적 의미의 단말 원격 제어 WebSocket 명령 수신/SMS/MMS 처리/지속성/프록시/터널은 보여도 단말 전체를 다루는 의미의 원격제어까지는 직접 확인되지 않았습니다.

I built MyLLM IOS & Android app that runs AI completely Free OFFLINE on your phone also i submit MyLLM AI App to @BagsHackathon and also create community token on @BagsApp $MyLLM CA - bags.fm/ASENQ7QunjJzL1twqJSP… No internet. We were promised an AI-powered future where personal assistants make our lives easier. But what we got were tethered, cloud-reliant tools that treat our personal data like their corporate fuel. It’s "personal AI," but it’s always listening, always sending your chats to a server, and always one outage away from being useless. That’s not freedom. That’s a digital leash. I spent the last few months head-down, battling the C JNI bridge, to build a solution that returns control to you. It’s called MyLLM AI. It is a native IOS & Android app that runs Large Language Models (LLMs) the power behind ChatGPT completely offline Free 100% on your phone. No internet. No API keys. No cloud servers. No monthly subscription. Your conversations are yours, full stop. This isn’t just about making an app; it’s about a mission. I wanted to prove that the 'personal' in Personal AI can mean private. I wanted to build something so small (~31MB APK) and so powerful that you can have intelligent conversations, build resumes, write code and even automate your entire phone using only the processor in your hand. And because this is about giving users back their agency, I gave it a soul: a full Material Design 3 Pokéball theme. It’s fun, it’s fast and it’s a pure uncompromised builder project. This is the main event. Designed to go viral within the builder, privacy, and Android developer communities. I’m putting GPT-4 in your pocket. Offline. I spent my nights battling CMake and the C JNI bridge to prove one thing: Your AI should not know your data. Introducing MyLLM AI 🔴a native Android app that runs LLMs completely on-device. No internet. No servers. Zero data ever leaves your phone. Here’s why this is a massive win for users:👇 1/ What is MyLLM AI? (The Core Mission) It's not another app talking to ChatGPT. It is a native LLM engine running directly on your phone using llama.cppthe same tech powering desktop local AI. It supports arm64-v8a and x86_64 architectures on most modern Android devices. The absolute data privacy you've been demanding is finally here. Conversations are stored in a local Room DB, full stop. 2/ The Tech Stack & Architecture (No Spaghetti) I built this with Kotlin Jetpack Compose and MVVM Clean Architecture. It uses Hilt for DI and WorkManager for background model management. The core is a ~400-line C JNI bridge, which was the hardest engineering puzzle of my life. This bridge allows the JVM (Kotlin) to stream tokens directly from a raw GGUF model in real-time, handling sampling and UTF-8 (emojis!) with atomic thread safety. 3/ What Models Can You Run? The app auto-detects your CPU/RAM and recommends the best fit. I support GGUF formatted models with Q4_K_M (4-bit) quantization: → Qwen 3.5 (from 0.8B up to 9B) → Llama 3.2 (1B, 3B) → Qwen 2.5 Coder (locally writing code) → Dolphin (the uncensored variant) 4/ The Actual Chat Experience Forget "waiting for the server." → Real-time streaming (words appear one-by-one) → Conversation history saved locally → Full multimodal support (input images!) → Local Speech-to-Text (STT) and Text-to-Speech (TTS) for hands-free mode 5/ This is Where it Gets Absolute INSANE (The Phone Control Agent) I added an experimental Accessibility Service agent that allows the offline LLM (or a Claude API fallback) to control your phone. It can: → Read your screen’s UI hierarchy → Tap buttons, swipe, type, and press back/home "Open my Settings and turn on Dark Mode" "Send a WhatsApp message to Mom" Your phone is now a true autonomous personal assistant. 6/ The Soul of the App: Pokéball Theme 🔴🟡 I am a Indie builder; I refuse to make something ugly.

Media3Watch: Loss of connectivity shouldn't mean lost data. Today I shipped offline resilience for our SDK! I built a custom file-backed queue to avoid the bloat of Room/WorkManager. Efficient session-keyed upserts ensure zero data loss on process restarts. #buildinpublic

Today's update for MobileClaw: my new open source project I'm building in public. MobileClaw - lightweight autonomous AI agent with Mobile UX designed to run on Android devices. 1) Implemented integration of MobileClaw with Telegram and other messengers. Now you can talk to you agent remotely. Please check the demo! 2) ZeroClaw core now runs on Android as a true background service: RuntimeAlwaysOnService WorkManager BootReceiver keep the daemon alive after app minimize/reboot. 3) Configure GitHub Releases: now you don't need to build MobileClaw agent from source code - you can download the recent .apk version directly from GitHub.

對但也不完全對，Activity 會被 onDestroy() 沒錯，但是那只是前景死掉了，service 跟 WorkManager 、 Socket 之類的東西還會繼續活著
