Android App Data Extraction / Scraping - CSV Export

@hirujiyu

Hi, ✔️ I see you are looking for a developer who can extract, filter, and organize contact data from an Android application while ensuring the final output meets your CSV formatting requirements. ➥ My approach: • Review the application's available data access methods and determine the most reliable and compliant extraction workflow • Validate the extracted records against your filtering requirements • Generate sample data for approval before processing the complete dataset • Deliver well-organized CSV files with consistent formatting ❓A few questions: 1. Do you have authorized access to the application and its data source? 2. Approximately how many records do you expect in the final dataset? 3. Is there any specific phone number format that should be preserved in the CSV (local or international)? I can start with the sample batch immediately and provide a clear timeline after reviewing the application's data access options. Thank you.

Hi — Elias here from Miami. I understand you're looking to extract contact data from a specific source and export it as a CSV. The goal seems to be efficiently gathering and managing this data for further use. The real challenge often lies in web scraping, especially with mobile app interfaces. A common issue is handling dynamic content and ensuring the scraper adapts to changes in the app's structure. It’s crucial to build a solution that is effective, maintainable, and scalable for future needs. I approach these projects by analyzing the target app’s flow and determining the best method for extraction, whether through API calls or reverse engineering. This ensures a robust solution that can handle changes without significant overhauls. I've worked on similar data extraction projects, ensuring reliability while maintaining performance. This experience allows me to foresee potential pitfalls and design a system that minimizes future headaches. A few questions to better understand the scope: Q1 – What specific data fields are you looking to extract? Q2 – Are there constraints regarding the frequency of data extraction? Q3 – How do you envision handling updates or changes to the data structure in the future? Happy to discuss the details and suggest the best technical approach. Looking forward to hearing from you.

Hi there, I understand the goal is to extract specific contact data from an Android application. Operationally, this means bypassing the UI to access the app's underlying data source-likely an API or a local database-then programmatically filtering all contacts to isolate phone numbers beginning with the digit '7', and finally structuring the resulting 'Name' and 'Phone' pairs into a clean CSV file. Technical approach: I'll start by analyzing the app's network traffic with a proxy like mitmproxy to capture API calls. If certificate pinning or encryption obstructs this, I will use Frida for dynamic instrumentation to hook the relevant functions and intercept the data post-decryption. A Python script will then handle the data processing, filtering, and final CSV generation. Core modules: - Network traffic interception and analysis. - Runtime data hooking (if API is secured). - Data filtering logic (for numbers starting with '7'). - Formatted CSV export. Implementation strategy: First, I will perform reconnaissance to identify the data source. Next, I'll develop the extraction script and provide the sample batch of 50-100 records for your validation. Upon your approval, I will execute the full scrape and deliver the final, complete CSV file. Questions: 1. Could you please provide the exact name and a Google Play Store link for the target Android application? 2. Are we targeting all contacts accessible within the app, or only those from a specific view like call history or search results? 3. For the 'starts with 7' rule, should we include numbers with a different country code but where the local number starts with 7 (e.g., '+44 7...')?

Hello, I will reverse engineer the Who Caller app's API traffic, identify the endpoints serving contact data, and deliver a filtered CSV containing only phone numbers starting with 7, with Name and Phone columns. On a similar extraction project, intercepting the app's API calls with mitmproxy proved far more reliable than scraping the UI layer. I will use the same approach here. Questions: 1) Is the target a specific region or country code prefix (e.g., +7 for Russia/Kazakhstan), or strictly any number where the local portion starts with 7? 2) Do you have a rough estimate of total records in the dataset, so I know whether pagination or rate limiting will be a factor? Share the exact app package name or Play Store link and I will deliver the 50 to 100 record test batch within 48 hours. Looking forward to discussing further. Best regards, Kamran

I can extract the Who Caller contact data and produce a clean CSV containing only the Phone and Name columns. I’ll first analyze the Android app’s network traffic and backend requests using tools such as mitmproxy/Frida, then reproduce the permitted API calls with a robust Python scraper. If the app uses certificate pinning or session protection, I’ll investigate that during the authorized analysis and use the appropriate technical method rather than relying on fragile screen scraping. The filtering will be applied before export: numbers will be normalized and only entries beginning with 7, including the +7 country-code format, will be retained. Other numbers will be excluded. I’ll also handle pagination, authentication/session data where provided, duplicate records, missing names, encoding, and CSV formatting. First, I’ll deliver a sample batch of 50–100 records so you can verify accuracy and filter compliance, followed by the complete CSV after approval. I can complete this in 3 days and bring 10+ years of development experience across Python, Android, APIs, reverse engineering, and scraping projects. Do you have an authorized test account or APK/API access for the Who Caller app? Muhammad Saad

@AhteshamAK

Hi, I understand you need filtered contact extraction from the Who Caller Android app, with only numbers starting with 7 and a clean Phone/Name CSV after a small verification batch. I can approach this carefully by first checking the app’s API traffic, then using controlled Reverse Engineering only where needed to understand request structure, authentication, pagination, and filters. If direct backend access is not possible, I can build a Python-based Web Scraping workflow around the available responses and export a validated CSV with duplicates and non-matching numbers removed. I’ll start with 50-100 records so you can confirm accuracy before full execution. Would you prefer the extraction to preserve the app’s original naming exactly, or should names be cleaned and standardized in the final CSV? Do you already have an account/session for the app that should be used? Also, should +7 country-code numbers be included exactly as-is or normalized into one phone format? Estimated delivery depends on volume and app protection, but the test batch can usually be shared first once access and scope are clear. Best, Ahtesham Ahmed

@opencollar

Hi, I see a challenge with extracting only contact numbers starting with 7 and making sure the data looks clean. I can handle data extraction by analyzing the app traffic and writing a simple script to filter the numbers. I'll make sure only numbers starting with 7 or +7 are included. Is your main concern accuracy of data or speed of extraction? Let's chat about a plan and develop a solution that does more than just this task. Regards, Nick. I’ve worked on projects like the sports app and marketplace, where you have to handle data carefully and efficiently, like in the TicketingHIPAAMedicalRecords or CarCRM demos, ensuring reliability and precision.

@gotucat

Hi, I reviewed the request for extracting contact data from an Android app and exporting a clean CSV with only phone numbers starting with 7, along with the matching Name. The core requirement is strict filtering: exclude every non-7 number from the final output. I’ll approach this using Python-based web scraping and Android data extraction. I’ll analyze the app traffic to locate the contact source (API/requests), or use backend scraping as needed, then parse results and apply the rule that only numbers beginning with digit 7 are kept. Finally, I’ll format the CSV with exactly Phone and Name columns. I focus on accuracy, a clean deliverable, and a verifiable sample batch before the full run. Let’s discuss here now.

@asifdwan

Hi, I can help extract and filter the required data from the target application, provided the information is publicly accessible and the extraction method complies with the app's terms of use and applicable laws. I have extensive experience with Python, API integration, mobile app analysis, and data extraction workflows. My approach is to first determine whether the app exposes an official API or accessible backend endpoints; if not, I'll evaluate other reliable data extraction methods appropriate for the application's architecture. The extracted data will be filtered to include only phone numbers beginning with **7** (or the specified country-code format), deduplicated, and exported to a clean CSV with **Phone** and **Name** columns. I'll first deliver a sample of 50–100 records for your verification before processing the complete dataset. I can also provide clean, well-documented code and an estimated timeline after reviewing the target app and its technical requirements.
