The APIs that have been being called recently are found to be unsuccessful and have been entangled for a long time. For more information, see tutorials and official documents, three steps are required.
1. Apply for app_id
2. Enter the package name. 3,
Obtain the MD5 value of the program signature,
You can call these three steps as long as you are right, but you do not know that sometimesThe keystore called by eclipse is different from the MD5 of the program signature obtained by the packaged key
After configuring the development environment (including Java environment variables)
----- 1. Find your Debug. keystore file in the eclipse tool,
Choose windows --> preference --> Android --> build,
The default debug keystore value is the path of DEBUG. keystore.
----- 2. Obtain the MD5 value of DEBUG. keystore.
First, run the CMD command line to enter the path where the debug. keystore file is located,
Run the following command:
