Android Google 地图 API 无法与 debug.keystore 一起使用

Question

I am attempting to create a MapView application following the tutorial from the Android website here . I have got everything set up and the map displays but with empty tiles!

The API key I'm using is generated from the debug.keystore located in "C:\Users\Pete\.android" and all of the correct permissions are set up in the manifest. The maps library is also in the manifest but it still doesn't work. I have tried creating a new debug keystore and placed it in the same folder (obviously also generating a new API key) and still no luck.

The <uses-permission> tags need to go outside of the <application> tag.

Your manifest file needs some reshuffling:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.stringerapps.testing.gps"
        android:versionCode="1"
        android:versionName="1.0">
   <uses-sdk android:minSdkVersion="8" />

     <!-- permissions -->
     <uses-permission
         android:name="android.permission.INTERNET">
     </uses-permission>
     <uses-permission
         android:name="android.permission.ACCESS_FINE_LOCATION">
     </uses-permission>
   <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Home"
              android:label="@string/app_name">
             <intent-filter>
                 <action android:name="android.intent.action.MAIN" />
                 <category android:name="android.intent.category.LAUNCHER" />
             </intent-filter>
        </activity>

     <!-- import the library com.google.android.maps!!! -->
     <uses-library android:name="com.google.android.maps" />


    </application>
</manifest>

Try that and I'll look through your other files to see if I can find anything else.

Important thing here is always to use proper fingerprint (keystore for fingerprint). I had the same problem before:). If you are debugging your application, use debug fingerprint as is described here and you will be safe. Then if you will decide to publish application then you will create own fingerprint for public use.
