With the release of Android 14, Google added an API to enable app developers to detect screenshots. This API has since been adopted by popular apps such as Snapchat. CaptureSposed is an Xposed module that effectively disables this API as well as the screen recording detection API added in Android 15. The app provides in-app switches to control each hook. You can also add optional Quick Settings tiles that mirror the in-app switches. ⚠️ WARNING: CaptureSposed is intended for rooted devices running Android 14 or newer and requires Xposed. The required Xposed variant to use is LSPosed. Other Xposed variants will not work. This module cannot be guaranteed to work on all devices. In the worst case, it can cause a bootloop. Use at your own risk. Additionally, this module does not protect against screenshot detection from apps that use the pre-Android 14 approach of using file system listeners to detect screenshots (ref 1, ref 2). To use CaptureSposed: 1. Install an LSPosed build with API 101 support. This requires your device to be rooted with Magisk or KernelSU. 2. Install CaptureSposed. 3. Grant root access to CaptureSposed. 4. Activate the CaptureSposed module in the LSposed user interface. 5. Reboot your device and sign in. 6. Open the CaptureSposed app and use the switches to enable or disable screenshot and screen recording detection blocking. Use the Testing card to verify that detection is blocked when expected. 7. Optionally, add the Block Screenshot Detection and Block Recording Detection Quick Settings tiles from the tile editor. These tiles mirror the in-app switches. CaptureSposed is a collaborative project by Keshav Majeti and David Berdik.

ChemSearch is a chemistry reference app for Android. Search compounds by name, CAS number, formula, PubChem CID, or drawn structure. Open formulas, identifiers, 2D structures, 3D models, descriptions, synonyms, and GHS safety summaries when source data is available. The app also includes a periodic table, a built-in chemical database, offline compound saves, recent searches, favorites, compound comparison, and practical chemistry tools such as molar mass, empirical formula, pH/pOH, oxidation state, reaction balancing, precipitation, stoichiometry, dilution, gas laws, SMILES lookup, and a local 3D molecule viewer. Most chemistry data comes from public sources such as PubChem, Wikipedia, Wikimedia Commons, UNECE GHS pictograms, Bowserinator/Periodic-Table-JSON, and the NCI/CADD resolver. AI descriptions are optional and require the user to add their own API key for the chosen provider. These optional providers use non-free network services, so the F-Droid build is marked with the NonFreeNet anti-feature. Safety information is for quick reference only. Always follow the official SDS, lab rules, and local safety requirements for real handling decisions.

Guessing the weight by New APLS Formula is just an approximation. The actual weight may differ markedly. I did not (yet) implement such a thing as a maximum weight nor a maximum dose. E.g. if you enter a weight of 500 kgs the App will calculate 2000 Joules defibrillation energy, 5 mg Adrenaline, and so on.

A TTS engine developed with Kotlin + JetPack Compose + Tensorflow Lite, which works totally offline. There are two models available: FastSpeech and Tacotron, both of which are from TensorflowTTS. Because the voice is generated in real-time, it has high performance requirements. The FastSpeech model works fast but the generated voice has poor anthropomorphic effect. It works well on a middle-end device. The Tacotron has high performance requirements. Though the overall effect is better, the speed is very slow. Therefore it's bundled only for test and can't be used in practice.

Automatic "ching" for practicing Thai music. * Sampled ching and glong sounds from real instruments. * Tempo selection. * Start playing with "chup chup" (the initial double-strike of the ching cymbals.) * Create your own drum patterns. I hope you enjoy this program! Please note that while this app contains both Thai and English translations and instructions for the most complicated functions, the majority of the user interface has been deliberately kept in Thai with the aim of encouraging interest in Thai script and the Thai language, as well as Thai music. I hope that the app also invites you, then, to be curious, push buttons, learn and explore, and have fun!
