Store the .rar file in your project's assets folder. During runtime, you can access and save that file to the phone's internal storage or the SD card. As I understand it, RAR is a propriatary format so you can't unarchive it using Java's SDK. Use a third party library like junrar to do the unarchiving.

I am working with googlemap. I have implemented custom marker window, this window contains photo of the marker. I am taking the url of the photo as string and setting it into imageview with thread. However, the code is not syncronized with user. When I have clicked the marker, it shows the photo of the previeus marker that I have clicked. When I did debug, I can see that true url values are coming from background but the setting image into imageview operation is becoming late. How can I solve this problem? I have tried picasso and glide but still same problem.
Are they expecting floating-point values? If so, then you must use the "decimal values."
Expressed in "Expressed in decimal degrees" as pointed out by the link I gave.
It's either degrees or radians
Assume, I'm quite familiar to distinguish between them;)
The curious Thing:
2.0 * ArcTan2(Sqrt(1.0 - xA), Sqrt(xA));
2.0 * ArcTan2(Sqrt(xA), Sqrt(1.0 - xA));
solved the cross check with Excel for the Moment. While the second one still is ok in c++
Why it solved it? For this I Need to bring back first trigo back into my mind.
All of this aside, where's the Android issue
Do you program for programming sake or do you even program to solve a task?
Ok, it is not Android specific, but while working with Android at the Moment, I thought I will ask this here. Now hang me higher because of this delinquency
