creating an app similar to navigator, need help

Thread moved to development forum for dev support.

 

You are essentially asking us to design the app for you. If you can't figure this out, you aren't quite ready to undertake this project. Take a step back, and do smaller apps first, preferably break down your application into smaller pieces and start with those.

 

Maybe the cache is saved in android/data/com.maps...
Or wait, doesnt it loads in the ram..

As a developer, you are in charge of serializing this data. It is not done for you out of the box.

 

Just to point you in the right direction, you need to walk it and endure it along the way


1: for speech to text look @ java - Speech to Text on Android - Stack Overflow

2: As far as I know this is not possible in free version of google map that you're planning to use. You have to pay big-G approx $10K US to get API's that allow you to do this. That said take a look at mytracks - MyTracks for Android - Google Project Hosting, it may give you some idea on using way-points and then using smoothing algorithms [not sure of the name, but look up the code].

3: Take a look at this example TextToSpeechActivity.java | Android Developers

4: Integration of all these is called the app, give it a shot, start out with small code, you'll stumble, fall, but eventually you'll get there

5: Google maps data is stored as binary in your on app private area /data/data/com.xx.yy/cache the files are named *tile*, for map tiles, though thats just the tile cache. Most of the data relevant to coordinates is fetched at runtime from google server, it is proprietary and they protected it and its format close to chest, though not saying you can't guess it i.e. bounding box of port etc.

May I add #6
Please do some research, people here will gladly help you about specific questions. But they won't do the job for you.

Good luck.
