Google Maps API V2 blank map after installation on real device

问题

When I emulate the app from eclipse using the device everything's OK, but after I generate the apk file and have it installed, my map is blank.

I followed these steps:

Generate a new keytool

keytool -genkey -v -keystore my-keystore-name.keystore
        -alias myKey1 -keyalg RSA -keysize 2048 -validity 20000

From Eclipse I "Export signed application package" using the keystore file (and key) I got from step 1.
Copy the apk to the device and select "package installer"

Manifest:

 <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="apt.login"

回答1:

You should try moving the <meta-data/> containing your API KEY to just before the closing tag.

You also don't have the following in there and you should:

<uses-feature android:glEsVersion="0x00020000" android:required="true"/>

回答2:

Why don't you create a new key from eclipse, Android Tools -> Export signed package, create new keystore.

Generate the SHA-1 key, use it to get the API key and place it in the meta data present in manifest file

回答3:

Use the keystore that you use for create .apk file of your project.

Open terminal and write below command keytool -list -v -keystore your_keystore_name -alias your_alias_name after your press enter it will ask you for password give your keystore password. press enter. it will genrate MD5 key & SHA1 key.(key like this)

SHA1: BB:0D:AC:74:D3:21:E1:43:67:71:9B:62:90:AF:A1:66:6E:44:5D:75

use this SHA1 key in googleconsole when you creating browser key for map.

This is work for me.
