Android Learning (I) Environment Establishment

Here I will not repeat so many installation steps. There are many articles in the garden to learn about.

Here is a link.

 

I encountered some problems during installation:

In general, open SDK manager.exe to download all the required items.

Sometimes panic: cocould not open: C: \ Documents ents and Settings \ Administrator \. Android/AVD/appears.

You need to set android_sdk_home = D:/Android-SDK-Windows/tools; (your location)

Then restart eclipse and you will be OK.

 

The first time you run the simulator, the speed is very slow.

 

After the task is completed, an error is returned when the second task is modified, similar to the following:

[2012-07-26 11:27:46 - demo] Re-installation failed due to different application signatures.[2012-07-26 11:27:46 - demo] You must perform a full uninstall of the application. WARNING: This will remove the application data![2012-07-26 11:27:46 - demo] Please execute 'adb uninstall com.example.demo' in a shell.[2012-07-26 11:27:46 - demo] Launch canceled!

E:\android-sdk\platform-tools>adb uninstall com.example.demoSuccess

Execute the statement as shown in the preceding figure. You can run the project directly without shutting down the simulator.
