I tried below code for a debug key and its working fine. When i make a apk then map is crashing. After searching in google i found debug key is work in release mode.
keytool -list -v -keystore "C:\Users\your_user_name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
So,how can i create a release key for v2 maps. please help me.
I didn't had the chance of doing that, but for my understanding what should be done is:
1. First of all you will need to export you project as a Signed Application:
Right click your project -> Android Tools -> Export Signed Application Package...
This will take you through wizard where you would have to create a new release.keystore with a password or use an existing one you created before.
2. From this point on the process should be identical to the one where you use the debug.keystore.
3. All the steps of creating a debug api key and registering it in Google API Console are described at this blog post I wrote:
4. Just remember that using the debug.keystore will not give you desired result.
Tyr this.. your directory where you have installed java and go to the bin folder.
For example-
C:\Program Files\Java\jdk_your_version\bin>keytool -list -v -keystore C:\Users\your_user_name\.a
ndroid\debug.keystore -storepass android -keypass android
i think it might help you.
C:\Program Files\Java\jdk_your_version\bin>keytool.exe -list -v -alias androiddebugkey -keystore C:\Users\your_user_name\.android\(Application).keystore -storepass YOUR_STORE_PASSWORD -keypass KEY_PASSWORD
Generally YOUR_STORE_PASSWORD and KEY_PASSWORD are same is "android".
