带有Google API的Android应用程序只能在模拟器上使用，而不能在手机上使用

Question

I have an Android App that uses the Google API, displaying a map and some markers on this map. When I run the app on an emulator, the app works as expected, but when downloaded on an actual Andorid Phone it crashes.

The phone runs on Android 2.3.3, and the Google API version 15. I have put this line in the AndroidManifest.xml-file:

<uses-sdk android:minSdkVersion="7" />

I have also signed the Google API key with the release keystore, and ensured that the same keystore was used when signing the application it self.

As mentioned, when run on an emulator the app works fine, BUT i do get this error when the app is starting (after instalation):

MainActivity  couldn't get connection factory client

And then there is a bunch of exeptions/warnings of this type:

System.err    IOExeption processing: 26
System.err    java.io.IOException: Server returned: 3

I'm new to Android programming, so I would appreciate any help that would solve this problem.

Answer 1

First check if appropriate permissions is set in AndroidManifest.xml. Check if you have provided correct google map key. To create Key http://www.pocketvnc.com/blog/?page_id=511 Also try to generate new MAP key and use it instead of using the old one.

Answer 2

For testing on real hardware you need to use a key different from the debug key. Following your post you are using a debug keystore.

https://developers.google.com/maps/documentation/android-api/v1/?csw=1#getfingerprint

Read that paragraph on google.

Is important that the application is exported as a signed application with the same key used for the google api (and NOT the debug key).

For create a valid read that paragraph:

http://developer.android.com/guide/publishing/app-signing.html#releasemode

and then use the same key to obtain the google maps api key.

Once you have the key for your application you can export a signed application by clicking with right button of your mouse on the project select Android Tools and then Export as a signed application package and follow the wizard (probably you can create a new key using that wizard).

hope that help.
