A developed program needs to be signed. In general, debugkey is used for development. If a program is released, its own signature is generally used, you can use commands to generate your own signature files, or eclipse or other development tools to generate them. The debugkey application method is as follows:
1. Find the debugkeystore File
The certificate path is generally in c: \ Documents ents and Settings \ current user \. androiddebug. keystroe. When eclipse is used for development, you can choose windows> preference> Android> build from eclipse. The default debug keystore value is the path of DEBUG. keystore.
2. Obtain the MD5 value of DEBUG. keystore.
Start> RUN> Enter cmd to open the command window and go to debug. the path of the keystore file. Run the following command: keytool-list-alias androiddebugkey-keystore debug. keystore. The system will prompt you to enter the password. Enter the default password "android" here ".
Debug key parameters:
Keystore name: "Debug. keystore"
Keystore password: "Android"
Key alias: "androiddebugkey"
Key password: "android"
CN: "Cn = Android debug, O = Android, c = us"
If: Android keytool is not an internal or external command
Then keytool is in the Java bin directory, all cmd CD to D: \ Program Files \ Java \ jdk1.6.0 _ 16 \ bin
Run: keytool-list-alias androiddebugkey-keystore "c: \ Documents and Settings \ ll \. Android \ Debug. keystore"
Obtain the MD5 value of DEBUG. keystore: 9f: 3D: 02: 75: 90: F3: C8: 80: CC: B2: F5: 39: 42: 60: A0: FD.
3. Apply for the API key for Android Map
Go to the Website: http://code.google.com/android/maps-api-signup.html, account, apply for adnroid map API key on the google website (if not available, you need to flip the wall, I use fg730x)
In my certificate's MD5 fingerprint, enter the MD5 value obtained in the previous step and click Generate API key to generate the key value, as shown in:
0ftnhhpgrqoec3hlkyg2ouavlqboqk-i5ma81na is the applied key
4. If it is your own key file, use the same method above to generate an MD5 value for it, and then go to the Google website to obtain the corresponding key.
