When launching Eclipse, the Android SDK Content Loader sometimes stuck at 0%, as shown in Figure 1.

The workaround is to turn off Eclipse first, and if it can't, shut down using Task Manager. Then enter the "C:\Users\Username\.android" folder, where "Username" is the system username. Delete the cache folder and ddms.cfg file in this folder, as shown in Figure 2.
Figure 2 cache folder and ddms.cfg file
Among them, the cache folder saves the Eclipse cache file; ddms.cfg is the configuration file of the Android platform's own debugging tool DDMS (Dalvik Debug Monitor Server). After deleting the cache file and configuration file, Eclipse will import the SDK using the default configuration.
At this point, launch Eclipse, the "Send statistics to Google" dialog box will pop up, as shown in Figure 3. Select "No" and then click the "Finish" button. The Android SDK Content Loader import starts and won't get stuck at 0%.
